Cannot find symbol class Intent | Android

This error may come when using Intent, and compiler throws above error. Possible solution for the above are

• Check the import statements at the top and make sure it includes the line:

  import android.content.Intent;

• Make sure both Activities are defined in your Manifest file.

  Intent intent = new Intent(this, NextActivity.class);
  startActivity(intent);

• Make sure the class dependencies are added in gradle.

  dependencies {
      ...
      implementation 'androidx.viewpager:viewpager:1.0.0'
  }
