Commencez par la trace de la pile et common/func/broadcastreceiver.py, en particulier BroadcastReceiver.Callback.__init__ et sa déclaration d’interface GenericBroadcastReceiverCallback. Reproduisez l’échec à l’exécution de l’APK et déterminez quelle modification permet au callback de s’initialiser sans la JavaException signalée ; le travail est terminé lorsque le récepteur de broadcast démarre correctement.
