I searched the other topics that relate to this matter and tried all the solutions but still it\'s driving me mad: <

Answer 1

You must update your

compileSdkVersion 28   &   targetSdkVersion 28

then Use

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

This is the stable release of Support Library 28.0.0 and is suitable for use in production. This will be the last feature release under the android.support packaging, and developers are encouraged to migrate to AndroidX.

Answer 2

add the below implementation in gradle file :

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

Answer 3

compileSdkVersion 28 & targetSdkVersion 28

change

Answer 4

add implementation 'com.android.support:support-v4:28.0.0' in your gradle

as an old version of com.android.support:support-v4:26.1.0 is there imported by some other library which is causing the issue with com.android.support:appcompat-v7:28.0.0, similarly add the other implementations that occur after this one. so final would be like

implementation 'com.android.support:appcompat-v7:28.0.0' 
implementation 'com.android.support:support-v4:28.0.0'
