Use soot to transform an APK file into Jimple files<br>2. Use soot to transform the Jimple files into a DEX file<br>3. Repack the new DEX file with the original resources/assets/...<br>4. Sign and zipalign the APK</p><p>Although none of these steps produces an error, the final APK is not executable and crashes instantly when launched (see [2]).</p><p>My questions are:<br>1. Is my goal as described above achievable with Soot at all?<br>2. If so, which of the previously described steps is most likely the culprit?</p><p>Any help is highly appreciated!</p><p>[1] <a
