If you using renderscript support library, and you try to upgrade the android tools version to 23.0.0. you will get the issue likes when compile your project :

UNEXPECTED TOP-LEVEL EXCEPTION:com.android.dex.DexException: Multiple dex files define Landroid/support/annotation/AnimRes;
at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554)
at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535)
at com.android.dx.merge.DexMerger.merge(DexMerger.java:189)

it cause the renderscirpt support library includes the annotation library's source code. you can solve this issue by adding a few of code in build.gradle

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