Failed to compile Android studio project

Question

I want to add a materialdrawer library to my project. When I add the dependency, my build.gradle looks like this

dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:22.1.1' compile('com.mikepenz:materialdrawer: 4.4.8@aar ') { transitive = true } } 

But then I get the following error:

 >Error:A problem occurred configuring project ':app'. > Could not resolve all dependencies for configuration ':app:_debugCompile'. > Could not find com.android.support:appcompat-v7:23.1.1.

How to fix it?

Answer 1

Be sure to update both the Android Support Repository and the Android Support Support .

And also make sure Gradle Sync is complete in Android Studio, as suggested by @diptia.

Answer 2

com.mikepenz: materialdrawer: 4.4.8@aar

A third-party library seems to require appcompat v23.1.1.

To solve this problem:

1) Make sure com.android.support:appcompat-v7:23.1.1 installed. Check through the SDK Manager.

2) Add compile 'com.android.support:appcompat-v7:23.1.1' to the build.gradle file.

3) Remove compile 'com.android.support:appcompat-v7:22.1.1' from your dependencies.
