Please, I’m begging you!

Solution

find the relevant code in decompiled apk:

  
public class SndActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(1);
        getWindow().setFlags(AccessibilityNodeInfoCompat.ACTION_NEXT_HTML_ELEMENT, AccessibilityNodeInfoCompat.ACTION_NEXT_HTML_ELEMENT);
        setContentView(C0085R.layout.activity_snd);
        Intent intent = getIntent();
        String action = intent.getAction();
        String type = intent.getType();
        if ("android.intent.action.SEND".equals(action) && type != null && HTTP.PLAIN_TEXT_TYPE.equals(type)) {
            String text = intent.getStringExtra("android.intent.extra.TEXT");
            if (text != null && "c95259de1fd719814daef8f1dc4bd64f9d885ff0".equals(sha1(text.toLowerCase()))) {
                ((TextView) findViewById(C0085R.id.sndTextView)).setText("Thank you!!");
                ImageView image = (ImageView) findViewById(C0085R.id.sndImageView);
                byte[] decodedString = Base64.decode(new StringBuilder(getString(C0085R.string.f16e) + "ROBVi").reverse().toString(), 0);
                image.setImageBitmap(BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length));
            }
        }
    }
