It is easier to use     sign in the version number  For example  compile  com android support support-v4 22 0    compile  com android support appcompat-v7 22 0      In this case you won t have to change versions for the same API number

Real path for Support Repository Libraries      You should download Support Repository Libraries    If the problem still exists    Go to the real path of your Support Repository Libraries and check that the following folder exists    ANDROID SDK DIRECTORY extras android m2repository com android support     In that folder there are support libraries that can t be found  for example    ANDROID SDK DIRECTORY extras android m2repository com android support appcompat-v7   Open folder appcompat-v7 and you see folders with all available version  You should use only one of these versions in the build gradle file  dependencies or use    for ex  18 0    dependencies       compile fileTree dir   libs   include      jar        compile  com android support appcompat-v7 18 0        compile  com android support gridlayout-v7 23 1 1      compile  com android support support-v4 23 1 1       That is the path taken from grade build dependencies file   com android support appcompat-v7 18 0 0   Refer to the real path on your HDD --    ANDROID SDK DIRECTORY extras android m2repository com android support appcompat-v7 18 0 0   If there is no such folder  you will receive the error    failed to resolve com android support appcompat-v7 18 0 0      p s   If you have Windows x64  when installing sdk and jdk  make sure that the installation path does not have Program Files 86   Brackets that add Windows may cause additional problems with resolving paths for your project  Use simple paths for your installation folder    For example   c  androidSDK

In order to make that working I had to set   compile   com android support support-v4 22 2 0   compile   com android support appcompat-v7 22 2 0   compile   com android support support-annotations 22 2 0   compile   com android support recyclerview-v7 22 2 0   compile   com android support design 22 2 0     compile   com android support design 22 2 0    Documentation states something different  docs    com android support support-design 22 0 0

NOTE1  All com android support libraries must use the exact same version specification  mixing versions can lead to runtime crashes    NOTE2  Support library should not use a different version than the compileSdkVersion  For API 28 you can use   implementation  com android support appcompat-v7 28 0 0-alpha1  implementation  com android support recyclerview-v7 28 0 0-alpha1    https   mvnrepository com artifact com android support appcompat-v7 28 0 0-alpha1 https   mvnrepository com artifact com android support recyclerview-v7 28 0 0-alpha1  All support libraries  https   mvnrepository com artifact com android support

These are the correct version that you can add in your build gradle according to the API needs   API 24   implementation  com android support appcompat-v7 24 2 1  implementation  com android support recyclerview-v7 24 2 1    API 25   implementation  com android support appcompat-v7 25 4 0  implementation  com android support recyclerview-v7 25 4 0    API 26   implementation  com android support appcompat-v7 26 1 0  implementation  com android support recyclerview-v7 26 1 0    API 27   implementation  com android support appcompat-v7 27 1 1  implementation  com android support recyclerview-v7 27 1 1

Fixed my issue by changing these   compile  com android support cardview-v7 21 0    compile  com android support recyclerview-v7 21 0      to   compile  com android support cardview-v7 23 0    compile  com android support recyclerview-v7 23 0      that means your target SDK version should be same as version of cardView and recyclerView and other google libraries   targetSdkVersion 23

User · Answer

I had such dependancy in build gradle -   compile  com android support recyclerview-v7      But it causes unstable builds  Ensure it works ok for you  and look in your android sdk manager for current version of support lib available  and replace this dependency with   def final RECYCLER VIEW VER    23 1 1  compile  com android support recyclerview-v7   RECYCLER VIEW VER

User · Answer

in support libraries you always need to add three numbers as version number  Suppose for 22 -  you need to write it as 22 0 0  not just 22  for 22 1 -  22 1 0  So your dependencies should look like this  compile  com android support appcompat-v7 22 0 0  compile  com android support support-v4 22 0 0  compile  com android support cardview-v7 22 0 0  compile  com android support recyclerview-v7 22 0 0    I Programmers language you need to pad extra zeros   Hope this solves your problem
