Since Android Studio is going to be default IDE for Android Development, I decided to migrate my existing project into Android-studio. The project stucture seems different and the hierarchy of folders in my Project is as follows:
Complete Project
->.idea
-> build
-> Facebook SDK
-> MainProject
-> ... (Other Libraries)
build.gradle
local.properties
settings.gradle
...
External Libraries
-> Android API 8 Platform
-> Android API 18 Platform
-> Android API 19 Platform
-> 1.7 Java
-> support-v4-19.1.0
My MainProject has a libs folder which contains different jars used within the project. It surprisingly does not contain the android-support-v4 jar which was present in my eclipse project. So, it seems that the external Libraries folder at the root must take care of it.
But after import, when I tried to compile the project started throwing "Symbol not found error" for Certain Classes all relating to android support library.
For Eg: The auto complete in Android Studio gives me suggestion for NotificaitonCompat from android.support.v4.app.NotificationCompat, but when I try to compile my Project Module it says
Error:(17, 30) error: cannot find symbol class NotificationCompat Error:Execution failed for task ':app:compileDebugJava'.> Compilation failed; see the compiler error output for details.
This happens in many other classes too for the same support library. I tried to insert a jar and changed the same in the build.gradle for the MainProject, but the error persists.
I even tried restarting and building the project again, but nothing changed.
EDIT:
I am attaching the Gradle file inside the MainProject
build.gradle in MainProject Module
apply plugin: 'com.android.application'
android {
compileSdkVersion 19
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "package.app"
minSdkVersion 8
targetSdkVersion 19
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
}
dependencies {
compile project(':facebookSDK')
compile project(':library')
compile project(':volley')
compile 'com.google.android.gms:play-services:+'
compile 'com.actionbarsherlock:actionbarsherlock:4.4.0#aar'
compile 'com.android.support:support-v4:19.1.0'
compile files('libs/FlurryAnalytics_3.3.3.jar')
compile files('libs/universal-image-loader-1.8.4.jar')
....
}
This part of your build file:
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
}
is telling the build system to ignore support-v4, which is why it isn't compiling. Remove that.
In your build file, you have this, which is the correct way to include support:
compile 'com.android.support:support-v4:19.1.0'
If you have the support library jar file in the libs directory of any of your modules, remove it and make sure you refer to it this way -- if you include the library as a jar, you're likely to run into a problem where the jar is included multiple times which will result in a dex error.
If you have jar files in a 'libs' directory, you can specify it in you build.gradle file :
dependencies{
compile fileTree(dir: 'libs', include: ['*.jar']
compile 'com.android.support:support-v4:21.0.3' //to automatically add up-to-date support lib
}
Hope this helps!

i saw similar questions, but not found accepted answers.
Problem - i have my own android library with some tiny functions.
My library uses others - f.e. Hawk (no sql database).
My library gradle file:
apply plugin: 'com.android.library'
buildscript {
repositories {
maven { url "https://www.jitpack.io" }
}
}
android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
minSdkVersion 18
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'library.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.0.2'
compile 'com.github.orhanobut:hawk:1.23'
testCompile 'junit:junit:4.12'
}
Library works fine. And if i use it as project inside another project - it work too. But when i generate *.aar file (with gradle -> assembleRelease) and include into separate project - it fails. Project see ONLY MY library's class. Hawk com.orhanobut.hawk package and ofc others (if i will use then) are not visible. So ClassNotFoundException comes.
If i remove
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'library.pro'
the result doesnt change.
I tried to add the following line into proguard file (library.pro)
-keep class com.orhanobut.hawk {public *;}
-keep class com.orhanobut.hawk.* {public *;}
Result is the same.
So i have two question:
1 - what should i do to make my main project see my library's third party dependencies?
2 - is is possible to obfuscate my library's code (only mine, not dependencies)?
what should i do to make my main project see my library's third party dependencies?
The aar file doesn't contain the transitive dependencies and doesn't have a pom file which describes the dependencies used by the module.
It means that, if you are importing a aar file using a flatDir repository you have to specify the dependencies also in your project.
You should use a maven repository, private or public, to avoid the issue.
In this case, gradle downloads the dependencies using the pom file which will contains the dependencies list.
Another way to solve the problem of dependencies is to get the jar files of the dependencies you want to use and place them in the libs folder of your module. This will copy all the your dependency jars into your library's jar or aar.
Note that I have emphasized jar because you cannot include aar file in libs folder, gradle still doesn't support aar file inside aar out of the box. There are a few gradle plugins like fataar which solve that problem.
I'm getting an error right after I installed Android studio and Created a simple app.

Android compile error; Java plugin has been applied, not compatible with android
Gradle error "Java plugin is not compatible with android plugins"
After File > Invalidate Cache/Restart
I think path has not been set as enviorment variable.
check have you declared the java sdk path . set the path as environment variable.
type "javac" in cmd(cmd must have admin previlliage).
If compile is not successfful
1 . Open the jdk location and copy the path of "bin"
2 . Open system properties in control panel.
3 . Advanced system settings -> then select "environment variables"
4 . click on "new"
5 . set variable name as "path" and variable value copied address
then try again
This means the Java plugin is being applied on top of the Android plugin. I don't see anything that stands out in your build files though. Some things to try:
Try doing a clean build from command-line. That will tell you if it's an Android Studio problem.
Create an empty app from a clean slate and see if it builds.
Update Android SDK to latest
Update Android Studio to the latest
Remove Android Studio project files and re-import
Make sure correct Java version is in your path and JAVA_HOME is set correctly
Check if there is any jars in your local lib folder that could be conflicting
Try using beta version of Android plugin compile 'com.android.tools.build:gradle:2.3.0-beta2'
I experienced this error while updating from KAPT to KSP. The docs say to add
id 'org.jetbrains.kotlin.jvm'
to the plugins block, but it appears that adding the Kotlin jvm plugin to the mix was causing my java plugin error. Remove the reference and it compiles. FYI the linked docs are more figurative than literal.
Not sure if this would help, but maybe you can try to explicitly add the java compilation option:
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
Try removing these two lines of code from your build.gradle
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
and
testCompile 'junit:junit:4.12'
Try this one
Procedure :-
1.right click on project ->Open Module Settings or F4
2.then goto SDK Location
3.after that Check on use embedded jdk(recommended)
you can see image given below
build and run project.
You can also add this in your build.gradle file
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
check if more than one jdk is installed.
I am not sure what this error means.

What could be the problem?
You've probably fixed this by now but just so this doesn't stay unanswered,
Try adding this to your build.gradle:
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
}
You need to check that you have inserted v4 library and compile library? You must not repeat library in your app or your dependence program.
delete the repeat library so that just one V4 remains.
in your app dir build.gradle file
add this command:
android{
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
all*.exclude group: 'com.android.support', module: 'support-annotations'
}
}
it works for me! You can try it!
I also came across this kind issue when re import old eclipse project. It occurred some old dependency as jar file in the project.
just remove
compile fileTree(dir: 'libs', include: '*.jar')
in gradle file
and add dependency in the gradle file.
It works for me ..
In my case the mentioned "duplicate entry" error arised after settingmultiDexEnable=true in the build.gradle.
In order to fully resolve the error first of all have a look at Configure Apps with Over 64K Methods (espescially "Configuring Your App for Multidex with Gradle").
Furthermore search for occurences of the class that causes the "duplicate entry" error using ctrl+n in Android Studio. Determine the module and dependency that contains the duplicate and exclude it from build, e.g.:
compile ('org.roboguice:roboguice:2.0') {
exclude module: 'support-v4'
}
I had to try multiple module labels till it worked. Excluding "support-v4" solves issues related to "java.util.zip.ZipException: duplicate entry: android/support/v4/*"
My understanding is that there are duplicate references to the same API (Likely different version numbers). It should be reasonably easy to debug when building from the command line.
Try ./gradlew yourBuildVariantName --debug from the command line.
The offending item will be the first failure. An example might look like:
14:32:29.171 [INFO] [org.gradle.api.Task] INPUT: /Users/mydir/Documents/androidApp/BaseApp/build/intermediates/exploded-aar/theOffendingAAR/libs/google-play-services.jar
14:32:29.171 [DEBUG] [org.gradle.api.internal.tasks.execution.ExecuteAtMostOnceTaskExecuter] Finished executing task ':BaseApp:packageAllyourBuildVariantNameClassesForMultiDex'
14:32:29.172 [LIFECYCLE] [class org.gradle.TaskExecutionLogger] :BaseApp:packageAllyourBuildVariantNameClassesForMultiDex FAILED'
In the case above, the aar file that I'd included in my libs directory (theOffendingAAR) included the Google Play Services jar (yes the whole thing. yes I know.) file whilst my BaseApp build file utilised location services:
compile 'com.google.android.gms:play-services-location:6.5.87'
You can safely remove the offending item from your build file(s), clean and rebuild (repeat if necessary).
check your dependencies versions, you must have compatible versions put attention specially to com.google packages, must have same version like:
compile 'com.google.android.gms:play-services:8.3.0'
compile 'com.google.android.gms:play-services-maps:8.3.0'
Both are 8.3.0, if you have another version compilation will throw that exception.
Simple Remove Your Jar file from dependencies gardle.project as v7
and run your project
For Expose.class Error i.e
java.util.zip.ZipException: duplicate entry: com/google/gson/annotations/Expose.class
use the below code
configurations {
all*.exclude module: 'gson'
}
find out the lib depends on the support v4, and exclude it.
code in build.gradle is like this:
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
// http://stackoverflow.com/a/30931887/5210
exclude group: 'com.android.support', module: 'appcompat'
exclude group: 'com.android.support', module: 'support-v4'
exclude module: 'recyclerview-v7'
}
In my situation, the lib 'espresso' has a jar called support-v4 and in my project 'app' have the same support-v4, exclude the support-v4 when import espresso.
PS: it seems compile project can not work with the exclude
This is because you have added a library and given its dependency on a module more than once.
In my case, I had added a library as a module and as a gradle dependency both.
Removing one source of adding library (I removed gradle dependency) solved my problem.
For Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug' com.android.build.api.transform.TransformException java.util.zip.ZipException duplicate entry com/google/gson/annotations/Expose.class
Here is what I did:
1) Delete the gson-2.5.jar file.
2) configurations { all*.exclude module: 'gson-2.5' }
I have faced this issue as i have manually copied the jar in libs as well as mentioned the dependency in gradle file. You also check in your project structure, whether the same jar file is copied in any other folder like libs or in project folder.
I had the same problem after upgrading the android SDK. I was able to run the application in the buildToolsVersion '23.0.1', I got the same error when I changed to buildToolsVersion '24.0.3'
I resolved the problem by updating my java version from 1.7 to 1.8 with compileSdkVersion 24
This problem cost me one whole day. I finally downgraded the firebase-ui library version from 2.0.0 to 1.2.0 and added the following code inside Project level build.gradle file:
allprojects {
repositories {
jcenter()
// Add the following code to your project level build.gradle
maven {
url 'https://maven.fabric.io/public'
}
}
}
I also have the issue because of i have compile 'com.android.support:appcompat-v7:24.0.0-alpha1' but i added recyclerview liberary compile 'com.android.support:recyclerview-v7:24.0.2'..i changed the version as same as compat like (24.0.2 intead of 24.0.0).
i got the answer..may be it will help for someone.
In my case the mentioned "duplicate entry" error arised after settingmultiDexEnable=true in the build.gradle.
and exact error which i was getting was below :
Error:Execution failed for task
':android:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException:
java.util.zip.ZipException: duplicate entry:
com/google/android/gms/internal/zzqx.class
So first thing I search for class which causes "duplicate entry" error using ctrl+n in Android Studio and searched for com/google/android/gms/internal/zzqx.class and then it was showing 2 entries for gms class with one version 8.4.0 and 1 with version 11.6.0 .
To fix it i made both to use 11.6.0 and it was fixed example
earlier
compile "com.google.android.gms:play-services-games:11.6.0"
compile "com.google.android.gms:play-services-auth:8.4.0"
compile "com.google.android.gms:play-services-ads:11.6.0"
After
compile "com.google.android.gms:play-services-games:11.6.0"
compile "com.google.android.gms:play-services-auth:11.6.0"
compile "com.google.android.gms:play-services-ads:11.6.0"
Rebuilding Fixed .
In my case exact error was below
':android:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/internal/zzqx.class
I was using another version of google apis i.e. in one modules gradle file
if (!project.hasProperty('gms_library_version')) {
ext.gms_library_version = '8.6.0'
}
however in other modules version 11.6.0 as below
compile "com.google.android.gms:play-services-ads:11.6.0"
compile "com.google.android.gms:play-services-games:11.6.0"
compile "com.google.android.gms:play-services-auth:11.6.0"
However to find this i did a ctrl + n in android studio and entered class name zzqx.class and then it displayed 2 jar files being pulled for this class and then i understood that somewhere i am using version 8.6.0 . On changing 8.6.0 to 11.6.0 and rebuilding the project the issue was fixed .
Hope this helps .

For me something similar happened when I had accidently added
apply plugin: 'kotlin-android'
to my android library module. Removing the line fixes the issue.
I tried all the above solutions but not working for me. I tried update libraries by goto project structure > app. And it works for me! Hope this answer helpful to someone.
Try this:
android {
configurations {
all*.exclude module: 'PhotoView' //去除重复依赖库
}
}
I need to use the commons-codec-1.9.jar from the commons-codec-1.9 library supplied by Apache. I've used this as a library in another project in NetBeans, so I already had the required .jar file that I needed to import. I copied the jar file from the NetBeans project and put it in my app project (app:libs folder) and right-clicked and chose the "Add as library..." option. I added it to my project dependencies as well via File > Project Structure > Dependencies. I created the import for the library in the classes I've written that use the library, and I get no errors and the code builds. However, when I run the app, it breaks and throws a NoSuchMethod exception... even though it is there.
Here are the contents of my build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion '20.0.0'
defaultConfig {
applicationId "com.example.<path_stuff>"
minSdkVersion 17
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/commons-codec-1.9.jar')
}
Here is my settings.gradle
include ':app'
I have also recently been getting a build error after I removed the commons-codec stuff from the libs folder and tried to re-add it. The error says something along the lines of "Build failed: could not find task 'assemble' in project " as if Android Studio thinks this is another project. Can someone please help me understand what is going on here and where I am going wrong?
No such method error details:
java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Base64.encodeBase64String
Edit: Realized I included the incorrect build.gradle file. Updated settings.gradle to remove the include statement. Included correct build.gradle and NoSuchMethod error.
Remove include ':libs:commons-codec-1.9: from your settings.gradle.
Add compile fileTree(dir: 'libs', include: '*.jar') to your dependencies block in your module's build.gradle file.
android {
...
}
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
This will automatically compile any .jar file in your libs folder into your project.
In my Android app, I'm getting a java.lang.NoClassDefFoundError when the code that references code in a dependent .jar is executed. My project includes an Android module as well as a java-only library module, which is where the jar dependency is. I'm using gradle 1.10 to build the project. Here is my project layout:
myProject
- app (Android)
- src
- build.gradle
- lib (java)
- src
- libs
- local-dependency.jar
- build.gradle
- build.gradle
- settings.gradle
The main project build.gradle is blank while the main project settings.gradle looks like:
include ':app', ':lib'
The Android app build.gradle looks like:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.8.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 18
buildToolsVersion "19.0.2"
defaultConfig {
minSdkVersion 18
targetSdkVersion 18
versionCode 1
versionName "1.0"
}
}
dependencies {
compile project(':lib')
}
The library build.gradle is:
apply plugin: 'java'
repositories {
mavenCentral()
}
dependencies {
compile <some-dependency-in-maven>
compile files('libs/local-dependency.jar')
}
Everything compiles and packages with no errors and I'm not seeing any errors in the IDE (IntelliJ 13). For some reason, my local-dependency.jar is not getting added to the dex-ing process during the Android compile. Any maven dependencies specified in the lib project get added to the Android .apk just fine; it's just my local jar dependency. Is there something I'm missing?
Thanks!
This is not directly possible as local jars are not declared as transitive dependencies in Gradle.
You have two options:
merge the two jars in your java library so that the output contains the local jar.
create a different project with no source, only the jar, and make the project depend on it.
The second option gives you the ability to have more than one project depend directly on the local jar (on top of it becoming a transitive dependency). To do it, create a new gradle project and just put in its build.gradle the following:
configurations.create("default")
artifacts.add("default", file('somelib.jar'))
This simply register your jar as the default artifact published by the project and this will get consumed by the other projects.
In recent (4+, IIRC) versions of gradle, you can achieve this with the following configuration:
compile (project(':ProjectIDependOn')) {
transitive = true
}
Setting transitive to true when depending on another project will expose all of that project's libraries to this project.
