My Headless
in foreground everything is ok but when i kill the app the headless run the code faster x10
this is my headless method:

void backgroundGeolocationHeadlessTask(bg.HeadlessEvent headlessEvent) async {
print("LOCATION PLUG-IN in BACKGROUND...");

PreferenceUtils.init();
kill();
bleStatus();

gps();
// checkInterNetLive();

helper.initializeDatabase();
getUserLocation(helper);
}

Debug logs

Additional context
this happened after i set the switch event on my headless, then everything works fine and good but every time i killed the app the app crashed and stopped working ,
Many thanks

This line shows your app has been upgraded to flutter sdk >= 1.12. You no longer need a custom Application.kt.

<meta-data android:name="flutterEmbedding" android:value="2" />

See the Android Setup

Modify your AndroidManifest.xml

<application
+        android:name="io.flutter.app.FlutterApplication"

i applied this changes and after that the background not worked at all

christocracy · 2020-06-14T20:07:28Z

Then you must figure out that problem.

Do NOT use a custom Application.kt with Flutter sdk >= 1.12

I also same issue? If your problem resolved Please Can you suggest me how to solve it?

uzirthapa · 2020-07-09T04:06:04Z

I Ran the example application for iOS and when I kill the application, and try to open it again, the app crashes on startup. Any fixes for this?

Also, please let me know if you need more details.

My version is iOS 14.0 and using on IPhone XR

christocracy · 2020-07-09T12:23:36Z

If the app crashes, provided the stacktrace here.

uzirthapa · 2020-07-09T12:41:18Z

When launching through XCode it is okay, this only happens once you kill the app and then try to reopen it.

Termination Reason: Namespace CODESIGNING

Open your app in XCode and configure your code-signing as required.

christocracy · 2020-07-09T12:54:05Z

Also see this that I found while googling "Termination Reason: Namespace CODESIGNING".

uzirthapa · 2020-07-09T12:59:46Z

I do have XCode Automatically Signing for me as well. I am trying the release build to see if that works.

uzirthapa · 2020-07-09T13:13:14Z

The release build works! But its interesting that if I close the app in debug mode, it crashes on restart. Will see if we can find a better solution for that. Otherwise I will work with the release build for now.

Thank you!
