Create the object and attach the listener:

...
PermissionManager mPermissionManager = new PermissionManager(this);
PermissionManager mPermissionManager.onAttach(this);
...

Override onRequestPermissionsResult and call PermissionManager method:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    mPermissionManager.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

Override onPermissionsGranted and onPermissionsDenied to handle permission response:

@Override
public void onPermissionsGranted(int requestCode) {
    switch (requestCode) {
        case PermissionManager.PERMISSION_READ_EXTERNAL_STORAGE_CODE:
            // action
            break;
        case PermissionManager.PERMISSION_READ_CONTACTS_CODE:
            // action
            break;
        case PermissionManager.PERMISSION_CAMERA_CODE:
            // action
            break;
            
        ...
            
    }
}
    
@Override
public void onPermissionsDenied(int requestCode) {
    switch (requestCode) {
        case PermissionManager.PERMISSION_READ_EXTERNAL_STORAGE_CODE:
            // action
            break;
        case PermissionManager.PERMISSION_READ_CONTACTS_CODE:
            // action
            break;
        case PermissionManager.PERMISSION_CAMERA_CODE:
            // action
            break;

        ...
            
    }
}

And finally, to use it, ask for the permission you want to use.

mPermissionManager.askForReadExternalStorage();

Don´t forget to add permissions in manifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
