The method requestPermissions on Fragments requires API level 23 or higher.
If your app targets a lower version you can use

FragmentCompat.requestPermissions(this,
            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            ConstantVariables.READ_EXTERNAL_STORAGE);

First you need to add the support-v13 dependency:

implementation "com.android.support:support-v13:$supportLibVersion"
