Question

Have recently upgraded to Android Studio 3.1, and at the same time I\'m trying the Android P preview.

I\'m getting the following error on compiling:

Answer 1

this error came,when i connect app to firebase.

no need to add any thing.

just put mouse cursor on error line(below one) and press Alt+Enter

(implementation 'com.android.support:appcompat-v7:28.0.0')

in the list enter first option.(noinspection)

After that it looks like this,

//noinspection GradleCompatible implementation 'com.android.support:appcompat-v7:28.0.0'

Answer 2

I think your gradle file has the below dependency. Add this to your app level build.gradle.

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:mediarouter-v7:28.0.0-alpha1'
implementation 'com.android.support:support-vector-drawable:28.0.0-alpha1'
implementation 'com.android.support:support-v4:28.0.0-alpha1'

Answer 3

You need to override the conflicted libraries by adding the conflicted libraries to your dependencies block. For example, from your error log you'll find the following:

Found versions 28.0.0-alpha1, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0-alpha1 and com.android.support:support-media-compat:26.1.0 less...

You can remove the error by adding the libraries with something like this:

dependencies {
   implementation 'com.android.support:animated-vector-drawable:28.0.0-alpha1`
   implementation 'com.android.support:support-media-compat:28.0.0-alpha1`
}

Answer 4

The above warning is not specific to media-compat dependency. They just added example to explain the issue. The issue get resolved by adding v4 lib for me.

implementation 'com.android.support:support-v4:28.0.0'

in addition to

implementation 'com.android.support:appcompat-v7:28.0.0'

No need include

implementation 'com.android.support:animated-vector-drawable:28.0.0'
implementation 'com.android.support:support-media-compat:28.0.0'
