Problem :

After updating my android studio to android studio 2.3 I facing below error message. I know it is giving me just the hint as my app is running normally but it looks really strange.

“All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0”

Solution :

You need to add explicitly a library with your old version but with the new version number which was my case it was com.android.support:customtabs:26.1.0 so I need to add the below one :

implementation "com.android.support:customtabs:27.0.2

Take your library from the second item, and just implement it with a version number from the first.

Note: Please do not forget to press the sync now so that the graddle can rebuild your dependency graph and it can also make sure if there are any more conflicts.

Detailed Explanation:
you may be baffled by your error message as it reads do not use the customtabs so how I have the conflict!!
Well you didn't use it straight but one of the libraries uses an older version of the customtabs internally, that’s why you need to ask for it directly.


Hope this solves your issue.

Few or one of your libraries exercise an old version of customtabs internally, that's why this warning message is displaying. In case you implement this with the latest version then the warning will be gone.

implementation 'com.android.support:customtabs:28.0.0'

Afterwards including this I have also displayed the same error for another older version of dependencies. After including this also all warning is gone.

implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'

Hope this will help you to solve your issue.


As of Android studio 3.0, it turns much easier as it currently shows a more helpful hint, so we just require to follow this hint.
for example:

All com.android.support libraries should employ the exact similar version specification (mixing versions can lead to runtime crashes). Found versions 27.0.2, 26.1.0. Examples included com.android.support:animated-vector-drawable:27.0.2 and com.android.support:customtabs:26.1.0

There are frw summation of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or specifically, a version lower than your targetSdkVersion.)

Include apparently the library with the old version however with a new version number.
in my instance com.android.support:customtabs:26.1.0 so I require to include:

implementation "com.android.support:customtabs:27.0.2"  

For example- Take the library from the second item, and performed it with the version number from the first.

Note: don't forget to press sync now so gradle can rebuild the dependency graph and view in case there are any more conflicts.


You may be distracted by the error message as don't employ customtabs so how I have a conflict!!
well. you didn't employ it directly however one of your libraries uses an old version of customtabs internally, so you require to ask for it directly.

In case you are inquisitive to know which of your libraries is responsible for the old version and maybe ask the author to update his lib, Run a Gradle dependency report, view the old answer to know how.

Problem: After upgrading to android studio 2.3 I get this error message. I know this is just a suggestion as the app runs normally, but it's really weird. All com.android.support libraries must use the exact same version of the specification (mixing of versions can lead to ... .maps.android:android-maps-utils:0.4.4' compile 'com.github.jd-alexander:library:1.1.0' } Hope I could find some help.
