Update

I think, You are having problem with Android SDK. Remove and reinstall Android SDK will solve the issue

First try to manually import ImageButton inside your ViewActivity for checking class inside the library is available or not

import android.widget.ImageButton;

then Add

implementation 'androidx.legacy:legacy-support-v4:1.0.0'

and remove

buildToolsVersion "29.0.2"

Sync and try again... let me know

  • I have try as you have suggested @majuran,But still the same. It seems that the class is not inside the library. – Gabriel Rogath Feb 02 '20 at 17:02
  • I have just Added it – Gabriel Rogath Feb 02 '20 at 17:17
  • Seems everything is fine. Close your Android studio then delete .gradle directory inside your project. Again open your project in Android studio. It'll download libraries again – majurageerthan Feb 02 '20 at 17:20
  • Deleted .gradle directory inside the project but still the same. I think as you @majuran have suggested that the class is not inside the library, and if this is the case how can you handle this? – Gabriel Rogath Feb 02 '20 at 17:34
