Firebase Version Conflicts With Support Library

I know this is a common question and I already read several posts and modify many times my gradle file but I can't find the solution. The error message is: All com.android.support

Solution 1:

Using gradle app:dependencies, get a list of dependencies:

 +--- org.jetbrains.kotlin:kotlin-stdlib-jre7:..
|    \--- org.jetbrains.kotlin:kotlin-stdlib:..
|         \--- org.jetbrains:annotations:...
+--- com.google.firebase:firebase-core:16....
|    +--- com.google.firebase:firebase-analytics:16...
|    |    +--- com.google.android.gms:play-services-basement:15....
|    |    |    \--- com.android.support:support-v4:26.1.0
|    |    |         +--- com.android.support:support-compat:26.1.0 ->.......

it shows firebase needed com.android.support:support-v4:26.1.0, so you have to overwritten it with com.android.support:support-v4:28.0.0

Solution 2:

change

dependencies{
implementation 'com.google.firebase:firebase-core:16.0.8'
}

dependency in your app gradle from

dependencies{
   implementation 'com.google.firebase:firebase-core:15.0.0'
}

and then sync your project with these changes.

Solution 3:

override your firebase dependency with

  com.android.support:support-v4:26.1.0

Happy Coding :)
