I was able to solve the problem in my react native project by simply adding

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

at the end of my android\app\build.gradle file

I started getting this error when upgrading to ButterKnife 8 5 1   None of the other answers here worked for me   I used gradle -q  app dependencies to see the tree  and then looked through jar files until I found the conflict   The conflict was that butterknife s dependency on com android support support-compat 25 1 0 contains a version of the accessibility class  and com android support support-v4 23 1 1 also contains the class   I solved it by changing my dependency from this   compile  com jakewharton butterknife 8 5 1    to this   compile  com jakewharton butterknife 8 5 1         exclude module   support-compat      It doesn t seem to affect ButterKnife s operation so far   Edit   There is a better solution  which was to upgrade my android support libraries to match ButterKnife s   compile  com android support appcompat-v7 25 2 0   compile  com android support design 25 2 0   compile  com jakewharton butterknife 8 5 1

Run gradle -q dependencies  or gradle -q  projectName dependencies  to generate a dependency report  You should see where r7 is coming from  such as   compile - Classpath for compiling the main sources   --- com commonsware cwac camera-v9 0 5 4       --- com actionbarsherlock actionbarsherlock 4 4 0            --- com google android support-v4 r7       --- com commonsware cwac camera 0 5 4       --- com android support support-v4 18 0   - gt  18 0 0  --- com android support support-v4 18 0   - gt  18 0 0   Then  use the exclude directive to block that dependency  In my case  it is coming from my CWAC-Camera library  and so I use   dependencies       compile  com commonsware cwac camera-v9 0 5 4           exclude module   support-v4             compile  com android support support-v4 18 0         where the second compile statement indicates what version you actually want   That should clear matters up  as you will see if you run the dependency report again   compile - Classpath for compiling the main sources   --- com commonsware cwac camera-v9 0 5 4       --- com actionbarsherlock actionbarsherlock 4 4 0       --- com commonsware cwac camera 0 5 4  --- com android support support-v4 18 0   - gt  18 0 0

exclude module   support-v4    Would not work for me with a project dependency  the only way I could get it to work was via the following syntax   configurations       dependencies           compile project   Android-SDK                  compile exclude module   support-v4                      Where  Android-SDK is your project name

This is an annoying problem  that can take some time to find out the root case  The way you should proceed is  CommonsWare answer    I faced this problem recently and found it hard to resolve    My problem was i was including a library by     version in build gradle  Latest version of library contained one of older dex and bang   I reverted to older version of library and solved it   It is good to run your androidDependencies and see what is really happening  Its also good to search in your build folder    Above all Android Studio 2 2 provide in build features to track this problem    Happy Coding Guys

Got it working for a compile file        conflict by increasing minSdkVersion to 21 and enabling multidex   Not sure if that is the best solution but the only way I could get it working in my case   Note  for compile file        it appears that you cannot put in an exclude clause so that option was not available
