All Com.Android.Support Libraries Must Use the Exact Same Version Specification

All com.android.support libraries must use the exact same version specification

You can solve this with one of the following solutions:

Update:

As of Android studio 3.0, it becomes much easier as it now shows a more helpful hint, so we only need to follow this hint.

for example:

All com.android.support libraries must use the exact same version
specification (mixing versions can lead to runtime crashes). Found
versions 27.0.2, 26.1.0. Examples include
com.android.support:animated-vector-drawable:27.0.2 and
com.android.support:customtabs:26.1.0

there are some combinations 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 in particular, a version lower than your
targetSdkVersion.)

Solution:

Add explicitly the library with the old version but with a new version number.

in my case com.android.support:customtabs:26.1.0 so I need to add:

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

ie: Take the library from the second item, and implement it with the version number from the first.

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

Explanation:

you may be confused by the error message as don't use customtabs so how I have a conflict!!

well.. you didn't use it directly but one of your libraries uses an old version of customtabs internally, so you need to ask for it directly.

if you curious 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, see the old answer to know how.

Note this

Old answer:

inspired by CommonsWare answer:

Run a Gradle dependency report to see what your full tree of
dependencies is.

From there, you will see which one of your libraries are asking for a different version of the Android Support libraries.
For whatever it is asking for, you can ask for it directly with the
25.2.0 version or use Gradle's other conflict resolution approaches to get the same versions.

Update:

As of gradle plugin version: 3.0 compile has been replaced by implementation or api see this answer for the difference.

hence use instead:

./gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath

or for windows cmd:

gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath

and search for the conflicted version.

For me, the error disappeared after removing com.google.android.gms:play-services:10.2.0

And only include com.google.android.gms:play-services-location:10.2.0 and com.google.android.gms:play-services-maps:10.2.0 as they are the only two play services that I use.

I think the gms:play-services depend on some old components of the support library, so we need to add them explicitly ourselves.

for AS 3.0 an older.

Run:

./gradlew -q dependencies <module-name>:dependencies --configuration implementation

Example:

./gradlew -q dependencies app:dependencies --configuration implementation

if someone knows a better way in the new gradle plugin please let me know.

Why do I get All com.android.support libraries must use the exact same version specification in Android Studio 3.2.1?

Some or one of your libraries use an old version of customtabs internally, that's why this warning message is showing. If you implement this with the latest version then the warning will be gone.

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

After adding this I have also shown the same error for another older version of dependencies. After adding 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 problem.
