Description
When the app is in the background, I want to use Android's Intent to bring app back to top. When the intent activates, the app instantly crashes and then restarts. This issue occurs with the new toolchain but not with the old one.
Code and Logs
Code to replicate:
***************
from kivy.app import App
from kivy.uix.button import Button
from android.broadcast import BroadcastReceiver

self.broadcast_receiver = BroadcastReceiver(
self.on_broadcast, actions=['provider_changed', 'run'])
self.broadcast_receiver.start()
noti.addAction(0, AndroidString("Start"), pending_intent)
if SDK_INT >= 16:
noti = noti.build()
else:
noti = noti.getNotification()
notification_service.notify(0, noti)
return True
def on_broadcast(self, context, intent):
print "On Broadcast"
activity = PythonActivity.mActivity
notification_service = activity.getSystemService(Context.NOTIFICATION_SERVICE)
notification_service.cancel(0)
intent = Intent(activity.getApplicationContext(), PythonActivity)
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_REORDER_TO_FRONT)
activity.getApplicationContext().startActivity(intent)
TestApp().run()
**************
Put app into background, which triggers notification. Touch notification to re-open app, and the app crashes with the following error:
A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x4 in tid 7199 (SDLThread)
More detailed logging reveals the following SIGSEGV fingerprint:
