Solution from Android Documentation is below
android {
defaultConfig {
// Required when setting minSdkVersion to 20 or lower
multiDexEnabled true
}
compileOptions {
// Flag to enable support for the new language APIs
coreLibraryDesugaringEnabled true
// Sets Java compatibility to Java 8
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.0.9'
}
This is working fine for Native android app, But this configuration is not working for React-Native app and throwing below error while building the app.
A problem occurred evaluating project ':app'.
Could not find method coreLibraryDesugaringEnabled() for arguments [true] on object of type com.android.build.gradle.internal.CompileOptions.
Half knowledge in always dangerous, and it happens here. As per the documentation above solution worked only for gradle version greater than 4. My gradle version was
classpath("com.android.tools.build:gradle:3.5.3")
I changed it to
classpath "com.android.tools.build:gradle:4.0.1"
Now it's working.
I've always programmed Android with Eclipse and decided to start migrating to Android Studio. I decided to use the same SDK I already had for Eclipse, then:
Started a new project
Set minimum SDK 4.0 (API Level 14)
Choose Blank Activity option
Used Default names for Activity Name and Layout Name
Hit Finish
After a few seconds Gradle finishes the build, and it throws me two errors with the following messages in file Teste4\app\build\intermediates/exploded-aar\com.android.support\appcompat-v7\23.0.0\res\values-v23\values-v23.xml:
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'.
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'.
Under File -> Project Structure -> Modules: app (left column) -> Properties tab, I have the following versions set up:
"Compile Sdk Version": Android 5.1 (API Level 22)
"Build Tools Version": 23.0.2
What should I do in order to fix this?
I already tried what was suggested in Stack Overflow question appcompat-v7:21.0.0': No resource found that matches the given name: attr 'android:actionModeShareDrawable', but it didn't work.
Your compile SDK version must match the support library's major version.
Since you are using version 23 of the support library, you need to compile against version 23 of the Android SDK.
Alternatively you can continue compiling against version 22 of the Android SDK by switching to the latest support library v22.
This happens because after updates Android Studio uses API version 23 by default.
The following worked for me:
Press Ctrl + Shift + Alt + S to get to the project structure page. Go to the properties tab and change 23.0.0 to 22.0.1 (or equivalent to what you were using earlier) in the build tool area and rebuild your project.
If that doesn't work, go to gradle:app and then
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
Edit v7:23.0.0 to v7:22.2.1 as shown above and sync gradle. This will definitely work.
When you update your Android Studio, it uses API version 23 by default,
which is the main reason for its occurrence. So,
At first, check your AppCompat version in build.gradle(Module:app)
That is,
If after changing to 23 there occurs an error then just download
Compile Sdk Version to API 23, and Build Tools Version to 23.0.0
from SDK Manager. If already downloaded then:
1. Go to SDK Manager and
2. Under Project Structure, change *Compile SDK Version* to API 23, and *Build Tools Version* to 23.0.0
Click the SDK Manager Button and open the dialog.
Click SDK Platform and check if Android 6.0 is downloaded or not.
if not, then download that first. After completing the download, click Apply.
Now you need to apply changes to your project from setting.
Then press Ctrl + Alt + Shift + S to open setting
Click the app from the list.
Click properties
Change your Compile SDK Version to API 23
Change your Build Tools Version to 23.0.0
Don't forget to rebuild your project.
Then your error will be gone.
If you've tried to change target to a previous GooglePlayServices or AppCompatv7 version and it doesn't work, check if you have any project-libraries dependency, this project will be targeting the latest version of any of these libraries. It happened to me with the Google Maps Utils Library project:
replace:
compile 'com.google.android.gms:play-services:+'
to
compile 'com.google.android.gms:play-services:8.3.0'
Then you can continue full targeting API 22
If it still doesn't compile, sometimes is useful to set compileSdkVersion API to 23 and targetSdkVersion to 22.
I agree with the previous answer. Your compile SDK version must match the support library. Here is what I did.
You can go to SDK Manager and under SDK Platform, install the Android 5.X with API level 23.
Under Project Structure, change compile SDK Version to API 23, and Build Tools Version to 23.0.0
Then it should build without problem.
You need to set compileSdkVersion to 23.
Since API 23 Android removed the deprecated Apache Http packages, so if you use them for server requests, you'll need to add useLibrary 'org.apache.http.legacy' to build.gradle as stated in this link:
android {
compileSdkVersion 23
buildToolsVersion "23.0.0"
...
//only if you use Apache packages
useLibrary 'org.apache.http.legacy'
}
This issue is raised because now the compile SDK version must match the Android Support library's major version.
In my case i have the Android Support Library version 23, so i had to compile against the Android SDK version 23, and I had to change this in my build.gradle file:
Well some of you will need to install the SDK, Android 6.0 (API 23)
and don´t forget to Sync project with gradle files
android {
compileSdkVersion 23
buildToolsVersion '23.0.1'
defaultConfig {
applicationId ""
minSdkVersion 14
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.android.support:recyclerview-v7:23.0.0'
compile 'com.android.support:appcompat-v7:23.0.1'
}
I found the solution, Problem started when I updated sdk, after that I used different buildToolsVersion ('22.0.1') and I was using different support library like compile 'com.android.support:appcompat-v7:23.0.0', showing you in image below
This was raising problem of "android.widget.Material..."
Then I used same version for support library like compile 'com.android.support:appcompat-v7:22.0.1' and its DONE. (Showing you in below screenshot)
You should compile your project with latest version so update & install from your SDK. Sync your project with sync project with Gradle file Button.
You can also continue with the existing version but check it installed properly below image indicate to API 22 that is properly installed.
And sync your project if needed.
it may help.
As pointed out by Tanis.7x, the support library version (23) does not match the targetSdkVersion (22)
You can fix this by doing the following:
In the build.grade file of your app module, change the following line of code
compile 'com.android.support:appcompat-v7:23.0.0'
To
compile 'com.android.support:appcompat-v7:22.+'
This will use the latest version of the appcompat version that is compatible with SdkVersion 22.
Your compile SDK version must match the support library major version. This is the solution to your problem. You can check it easily in your Gradle Scripts in build.gradle file.
Fx: if your compileSdkVersion is 23 your compile library must start at 23.
compileSdkVersion 23
buildToolsVersion "23.0.0"
defaultConfig {
minSdkVersion 15
targetSdkVersion 23
versionCode 340
versionName "3.4.0"
}
dependencies {
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:recyclerview-v7:23.0.1'
}
And always check that your Android Studoi has the supported API Level. You can check it in your Android SDK, like this:
In my case it was an higher version of Google-play-services. I set them to 7.0.0 (not 8.x) and all was ok.
I wanted to downgrade from API 23 to 22 and got this error. I had to change all build.gradle files in a project in order to compile.
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.yourapp.app"
minSdkVersion 14
targetSdkVersion 22
}
...
dependencies {
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:support-v4:22.2.1'
compile 'com.android.support:design:22.2.1'
compile 'com.google.android.gms:play-services-gcm:10.0.1'
}
This is what helped me: Adding specific android platform
What should be done is the following... In my case it was cordova but the same is relevant for ionic, phonegap and other frameworks like these:
list all platforms installed for your project: cordova platform list. You'll see something like this:
remove the android platform: cordova platform remove android.
then add the specific android platform: cordova platform add android#5.0.0.
Good luck! :)
I got the same problems. I solved my problem by updating gradle.build for each sub-module to latest compiler version.
Another solution :
navigate to
\sdk\extras\android\m2repository\com\android\support\appcompat-v7\23.x.x
open .aar file with 7-zip or winrar , in res folder remove values-23 folder and save changes .
on module: app (Gradle)
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.namepack.nameappxxxxx"
minSdkVersion 16
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}
project: nameAppXXXX (Gradle)
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.2.3'
}
}
allprojects {
repositories {
jcenter()
}
}
and edit your activity of AppCompatActivity to for example Activity:
package com.namepack.nameappxxxxx;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
public class NameClass extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
}
}
Everything is great but none of you explained where to download the SDK build tools
Make sure that all these are in upto date.
Upgrade Android Studio.
I had this issue with Android Studio 1.3.1 and none of the other answers worked for me, but after updating to 1.5.1 there were no problems.
If you are using phonegap(cross-platform) and got same issue above,
just remove the android platform using below command.
phonegap platform remove android
And add it again.
phonegap platform add android
Then problem solved for me.
If you are getting errors even after downloading the newest SDK and Android Studio, here is what I did:
Download the most recent SDK
Open file-Project structure (Ctrl + Alt + Shift + S)
In modules, select app
In the properties tab: Change compile SDK version to API 23 Android 6.0 marshmallow (latest)
I hope it helps someone so that he won't suffer like I did for these couple of days.
As others have already mentioned your compile sdk version must match your support library's major version. This is however, also relevant for subprojects should you have any.
In case you do, you can set your subprojects compile sdk versions with the following script:
subprojects { subproject ->
afterEvaluate{
if((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion
}
}
}
}
Add this script in your root build.gradle file.
The library I'm using is bychan, I can't even include it in a Nougat empty app project either loaded as module or through jar.
So this is an example of what was returned in Android Studio's messages:
Can someone explain what they mean by "unknown interface" in the errors below?
Error:TokenDefinitionBuilder.java:118-119: Lambda coming from jar file need their interfaces on the classpath to be compiled, unknown interfaces are java.util.function.Function
Error:TokenDefinitionBuilder.java:118-119: Lambda coming from jar file need their interfaces on the classpath to be compiled, unknown interfaces are java.util.function.Predicate
...
Error:com.android.jack.JackAbortException
This came from a library I've used. I thought adding the types in angle brackets would help? I don't know if it did anything though.
This is the line 118-119 in that library:
strings.stream().<StringMatcher>map(StringMatcher::new).map(
m -> m.tryMatch(input, searchStart)).filter(Objects::nonNull).findFirst().orElse(null));
I'm not sure what it is complaining about? What should I do or change to evade this problem? I had thought that maybe Android doesn't support Lambda Expressions, but the error clearly stated "Lambda coming from...", which means it recognized I used a lambda expression.
Please help.
Update
I have included the library by compiling it in a jar inside another jar library, if that helps. I'm new to the world of Android if you can't tell.
Updates 2
I don't think this is related to the API version? I've set my build target to 25. But the build is still failing.
Also, if you look below, I don't see an option for 1.8? But I've set the build JDK to my 1.8 JDK location.
Gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
applicationId "this.is.where.i.have.my.id"
minSdkVersion 25
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
jackOptions {
enabled true
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.android.support:support-v4:25.0.0'
compile 'com.android.support:design:25.0.0'
compile 'com.android.support:preference-v7:25.0.0'
compile 'com.android.support:preference-v14:25.0.0'
compile 'com.google.android.gms:play-services-appindexing:9.8.0'
testCompile 'junit:junit:4.12'
compile 'com.google.code.gson:gson:2.8.0'
compile files('libs/my_lib_that_contains_lambda.jar')
}
I would not suggest to use java 8. It is not supported nowadays. But, even, it will: remember, that each devices has got its own java machine that will not update. I mean, if you wanna be sure your app works properly setup your project as java 6. Old devices this never support up-to-date JMV
Read this discussion too
Which JDK version (Language Level) is required for Android Studio?
Android SDK < 24 does not support java.util.function.Function and java.util.function.Predicate interfaces because Java 8 allows functional interfaces to contain default methods which is only supported in SDK 24 and above. I had this problem when I was using consumers, and the way I fixed it was to create my own clown of java.util.function.Consumer interface without all the default methods.
You can also fix this issue by increasing the minimum SDK of your app to 24.
Update
Add the following to your build.gradle file
defaultConfig {
jackOptions {
enabled true
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
Overall set up looks good to me except for the Java JDK 1.8 part.You need to set a correct path to JDK installation folder in Android Studio in order to use all the new Java 8 features.
So I update my project to use the new jack compiler, but for some unknown reason my AntiVir blocks the task transformClassesWithPreJackPackagedLibrariesForDebug
It works if I disable AntiVir real-time protection. I really don't want to do that and I don't want to start putting my android project in the exception list.
I am using Android Studio 2.2 and this is my build.gradle
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
minSdkVersion 21
targetSdkVersion 24
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
jackOptions {
enabled true
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
My project.gradle
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0'
}
}
And the error when I try to run the app on my hardware device.
Error:Execution failed for task ':app:transformClassesWithPreJackPackagedLibrariesForDebug'.
> Failed to delete temporary file C:\Users\User\AppData\Local\Temp\jill-1475579265083-0.jack
While compiling disable real-time protection in your anti-virus package. It is the only workaround that is reliable at this time.
You could add your Android SDK, Android Studio and project folders to your antivirus whitelist. This way you will still be protected while building.
Guide here.
Fixed using 'com.android.tools.build:gradle:2.2.0-alpha5'
if not working than please add your Android SDK, Android Studio and project folders to your antivirus whitelist:

[Fixed]
Thanks to #Visil below (accepted answer). I added the recommended code to build.gradle and waited after syncing gradle. The following popped up shortly after that...
Original Question
I am doing some Android programming with Android Studio 0.5.9, and I wanted to have some String switch statements. I set up everything, but the compiler is complaining that it cannot handle them.
String Switch-statements were introduced in JDK 1.7 so I am confused as to why I cannot do this.
Just to prove I am using JDK 1.7, you can check the image below...
...also, my machine has JDK 1.8 installed...
...what's up with this?
[UPDATE]
File >> Other Settings >> Default Settings
File >> Other Settings >> Default Project Structure
Build.gradle
Please check your gradle source compatibilty configuration:
With Android KitKat (buildToolsVersion 19) you can use the diamond
operator, multi-catch, strings in switches, try with resources, etc.
To do this, add the following to your build file:
android {
compileSdkVersion 19
buildToolsVersion "19.0.0"
defaultConfig {
minSdkVersion 7
targetSdkVersion 19
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
Note that you can use minSdkVersion with a value earlier than 19, for
all language features except try with resources. If you want to use
try with resources, you will need to also use a minSdkVersion of 19.
You also need to make sure that Gradle is using version 1.7 or later
of the JDK. (And version 0.6.1 or later of the Android Gradle plugin.)
