gradle dependency error in android

Question

Answer 1

Found a solution to this:

1. Removed the config section in the build.gradle that excludes support-v4

2. It turns out that .aar files are basically a zip, so removed the support-v4 jar from the dependency .aar library (using 7-zip). And now, I don't get the top-level exception and at the same time able to use recyclerview-v7.

If you are using dependency projects instead of .aar files, try removing the support-v4.jar files in the dependency projects before compiling.

Shouldn't the gradle build tool be intelligent enough to exclude the duplicate packages rather than having the users go thru this kind of workarounds and headaches?

Answer 2

I fixed that adding:

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

Answer 3

If you're having a dependency conflict with the v4 support library, you can just exclude it from one of the libraries via the gradle script:

compile ('com.android.support:recyclerview-v7:+') {
    exclude module: 'support-v4'
}
