Couldn't compile android studio project

Question

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

 dependencies {
    compile fileTree(dir: \'lib         


        

Answer 1

com.mikepenz:materialdrawer:4.4.8@aar

It seems like the third party library requires the appcompat v23.1.1.

To solve it :

1) Make sure that com.android.support:appcompat-v7:23.1.1 is installed. Check via your SDK Manager.

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

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

Answer 2

Make sure to update both "Android Support Repository" and "Android Support Library".

And also ensure the Gradle Sync is completed in Android Studio as @diptia suggested.
