[FIXED] Solution: java.lang.NoSuchMethodError: No static method isCtrlPressed(Landroid/view/KeyEvent;) OR (Landroid/support/v4/view/KeyEventCompat)

Issue

As I had problems with

java.lang.NoSuchMethodError: No static method isCtrlPressed(Landroid/view/KeyEvent;)

and with

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/view/KeyEventCompat

I wanted to help u and show u how i managed to solve these problems.

I use:

 compileSdkVersion 27
 minSdkVersion 21
 targetSdkVersion 27
 versionName '2.6'
 versionCode 8
 buildToolsVersion '27.0.3'

I needed just to remove all old support dependencies from the gradle (for example: com.android.support:support-v4:25.1.0). And then add those two lines:

- implementation 'com.android.support:support-v4:27.1.0'

- implementation 'com.android.support:appcompat-v7:27.1.0'
