I can't run an android app because of a seemingly missing unknown parent resource? [duplicate]

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.

'java' plugin is not compatible with the Android plugins

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.

SafePassmaster ---> Error:(1, 0) Plugin with id 'com.android.application' not found

I have imported a android source code from Github and while syncing the gradle process I have got an error
Error:(1, 0) Plugin with id 'com.android.application' not found.

Try changing the classpath in the top level build.gradle file to 'com.android.tools.build:gradle:2.0.0-beta7' and the distributionUrl value in gradle-wrapper.properties file to https://services.gradle.org/distributions/gradle-2.10-all.zip.
Make sure that in the settings for gradle in the 'Build, execution and deployment' section, you have set the preference to 'Use default gradle wrapper'.

As the other answer described, try changing the classpath in the top level build.gradle file. The file you show is the application build.gradle, not the top level build.gradle file. For Android Studio 3, you can try using 'com.android.tools.build:gradle:3.0.1'. The problem is that the gradle dependency is not downloading properly, usually because of improper settings for the url to use to download gradle. This is a common problem. If the problem persists look into solutions for how to set up gradle, such as Manually install Gradle and use it in Android Studio
A quick-and-easy fix is to look at your previous projects which work on your IDE, look at what version of gradle they are using. If you use that version of gradle in this project it will most likely work.
However, the 'proper' solution is to set up the distributionUrl properly. Worst come to worst, if that does not work, you could also try manually downloading Gradle to use it in your project.

Gradle fails to resolve dependencies in Android Studio

Whenever I add a dependency from an remote repository (jcenter) in Android Studio 1.1 (OS X) I get the following error upon syncing Gradle:
Error:(26, 13) Failed to resolve: <packagename:version>
My app's build.gradle is as follows:

compile 'com.google.android.gms:play-services:6.5.87'
compile 'org.json:json:20141113'
}
I have tried changing repositories (jcenter(), mavenCentral(), etc.), reinstalling Android Studio, JDK (7 and 8), changing Gradle version and Android SDK version, none of which worked. Upon running ./gradlew build I get:
Could not resolve com.android.tools.build:gradle:1.1.0.

This is an error I get in other cases as well, for example when trying to use Intellij Idea instead of Android Studio. Running the app without the dependency does work though.

A similar problem here, and when I choose Build -> Clean Project
there is a "peer not authenticated" error.
solved by using "http://jcenter.bintray.com/" instead of "https://jcenter.bintray.com/"
repositories {
jcenter({url "http://jcenter.bintray.com/"})
}
hope this work for you.

I had a similar problem with a library on github, which stated to install it as:
dependencies {
compile 'com.github.chrisbanes.photoview:library:1.2.4'
}
This workaround seem to work, although it's suboptimal because it doesn't fetch a specific version and leads to Android Studio warnings:
dependencies {
compile 'com.github.chrisbanes.photoview:library:+'
}

In my case, the problem was I was declaring jitpack in buildscript.repositories instead of allprojects.repositories in my package build.gradle.
Instead of:
buildscript {
repositories {
...
maven {
url "https://jitpack.io"
}
}
}
It should be here:
allprojects {
repositories {
...
maven {
url "https://jitpack.io"
}
}
}

Rather late but probably your gradle works in offline mode.
Go to File->Settings->Gradle and uncheck the offline mode.
Then try to refresh gradle and it should work

I am behind a corporate firewall. I had my http settings set, but not my https settings. So, I added the following to my gradle.properties file:
systemProp.https.proxyPassword=...
systemProp.https.proxyHost=...
systemProp.https.nonProxyHosts=...
systemProp.https.proxyUser=...
systemProp.https.proxyPort=...

When I added this com.droidninja:filepicker:2.2.5 dependency in my build.gradle (Module Level) file then I got this error.

dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
// Add this line
gradlePluginPortal()
}

It worked for me.

In my case I added this to my build.gradle (module:app):

However, it gave me an error today. My solution is to use this instead:
compile 'com.github.glomadrian:velocimeterlibrary:+'

Gradle Android Maven Plugin doesn't create the pom file automatically

I would like to know how to create a pom file with "Gradle Android Maven Plugin".
I followed the steps on http://www.gradle.org/docs/current/userguide/maven_plugin.html (chapter "Convention Methods"). I also created the directory "buildDir" and get no errors. The App was build successfully but nevertheless the pom file doesn't exist. I am using Android Studio IDE.
Is it possible that the newpom.xml file exists on runtime only and does not exist in my project folder buildDir after runtime? Maybe I am looking for something which can't be found.
My app/build.gradle looks like this:
apply plugin: 'android'
android {
compileSdkVersion 19
buildToolsVersion "19.1.0"
defaultConfig {
minSdkVersion 16
targetSdkVersion 19
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
apply plugin: 'maven'
task writeNewPom << {
pom {
project {
inceptionYear '2008'
licenses {
license {

}
}
}
}.writeTo("$buildDir/newpom.xml")
}

compile 'com.google.code.gson:gson:2.2.4'
compile 'com.android.support:appcompat-v7:+'
compile files('libs/retrofit-1.5.1.jar')
}
Can someone tell me if I missed something? :)

No need to create buildDir manually, it has default value and refer to /build folder that place in same folder as build.gradle file.
Did you run follow command?
gradle writeNewPom
after run it I got newpom.xml file in projectroot/build folder, BUT it contains no dependencies however I have dependencies in build.gradle file.
