Buggy source:

Fixed version (ground truth):

  Bundle data=msg.getData();
  String error=data.getString(Apg.EXTRA_ERROR);
  if (error != null) {
    Toast.makeText(EncryptActivity.this,getString(R.string.errorMessage,error),Toast.LENGTH_SHORT).show();
    return;
  }
switch (mEncryptTarget) {
case Id.target.clipboard:
{
      String message=new String(data.getByteArray(Apg.EXTRA_ENCRYPTED_MESSAGE));
      ClipboardManager clip=(ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
      clip.setText(message);
      Toast.makeText(this,R.string.encryptionToClipboardSuccessful,Toast.LENGTH_SHORT).show();
      break;
    }

    if (mReturnResult) {
      Intent intent=new Intent();
