## How To Solve
1. Decompile the APK, (e.g. using JADX or online: http://www.javadecompilers.com/apk). 
2. Figure out the (rather simple) logic of the app, which is located in the `MainActivity.java` file: 
    - The decoded flag is shown in a toast whenever the code is correct.
3. The code is a construction of strings fetched from `resources/res/values/strings.xml`.
4. Reconstruct the code, enter the code in the app and the flag will be shown.

The correct code is 7402583711.
