Answer 1

I fixed that adding:

compile ('com.facebook.android:facebook-android-sdk:3.22.0@aar'){ exclude module: 'support-v4' }

Answer 2

Try this :

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
}

Answer 3

Remove google analytics V2 helps for me

Answer 4

I got this error today out of nothing, after that i tried to update every single thing available, tried to change my gradle build as suggested here but none of it worked.

After hours of dispair and AS updates, a simple "clean project" and "rebuild project" worked for me.

Answer 5

Just rebuilding project fixes the issue (Build->Rebuild Project). You can also clean project

Answer 6

If you have support-v4 and support-v7 (with different version) in build.gradle then add this line into your build.gradle at top.

configurations { all*.exclude group: 'com.android.support', module: 'support-v4' }
