## 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.
