Buggy source:
@Override public void doneCallback(Message msg){
  super.doneCallback(msg);
  removeDialog(Id.dialog.encrypting);
  Bundle data=msg.getData();
  String error=data.getString("String_Node_Str");
  if (error != null) {
    Toast.makeText(EncryptActivity.this,getString(R.string.errorMessage,data.getString("String_Node_Str")),Toast.LENGTH_SHORT).show();
    return;
  }
 else {
    String message=data.getString("String_Node_Str");
switch (mEncryptTarget) {
case Id.target.clipboard:
{
        ClipboardManager clip=(ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
        clip.setText(message);
        Toast.makeText(this,R.string.encryptionToClipboardSuccessful,Toast.LENGTH_SHORT).show();
        break;
      }
case Id.target.email:
{
      Intent emailIntent=new Intent(android.content.Intent.ACTION_SEND);
      emailIntent.setType("String_Node_Str");
      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,message);

      }
      EncryptActivity.this.startActivity(Intent.createChooser(emailIntent,getString(R.string.title_sendEmail)));
    }
case Id.target.file:
{
    Toast.makeText(this,R.string.encryptionSuccessful,Toast.LENGTH_SHORT).show();

Fixed version (ground truth):
@Override public void doneCallback(Message msg){
  super.doneCallback(msg);
  removeDialog(Id.dialog.encrypting);
  Bundle data=msg.getData();
  String error=data.getString("String_Node_Str");
  if (error != null) {
    Toast.makeText(EncryptActivity.this,getString(R.string.errorMessage,data.getString("String_Node_Str")),Toast.LENGTH_SHORT).show();
    return;
  }
 else {
    String message=data.getString("String_Node_Str");
switch (mEncryptTarget) {
case Id.target.clipboard:
{
        ClipboardManager clip=(ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
        clip.setText(message);
        Toast.makeText(this,R.string.encryptionToClipboardSuccessful,Toast.LENGTH_SHORT).show();
        break;
      }
case Id.target.email:
{
      Intent emailIntent=new Intent(android.content.Intent.ACTION_SEND);
      emailIntent.setType("String_Node_Str");
      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,message);
      if (mSubject != null) {
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,mSubject);
      }
      if (mSendTo != null) {
        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{mSendTo});
      }
      EncryptActivity.this.startActivity(Intent.createChooser(emailIntent,getString(R.string.title_sendEmail)));
      break;
    }
case Id.target.file:
{
    Toast.makeText(this,R.string.encryptionSuccessful,Toast.LENGTH_SHORT).show();
    if (mDeleteAfter.isChecked()) {
      setDeleteFile(mInputFilename);
