App showing ANR(App Not Responding)

[mpriyanka2k]

Below are the older stable and functional versions of the libraries and tools integrated into my Flutter application:

1.flutter_background_geolocation(Version: 4.12.3) - Transistor Software
2. Flutter SDK: Version 3.16.9
3. Android Studio: Giraffe | 2022.3.1
4. permission_handler: Version 11.0.1
5. location: Version 4.0.0

The current versions of libraries and tools integrated into my Flutter application are as follows:

1. flutter_background_geolocation: Version 4.16.6 (Transistor Software)
2. Flutter SDK: Version 3.24.3
3. Android Studio: Hedgehog | 2023.1.1 Patch 2
4. permission_handler: Version 11.3.1
5. location: Version 7.0.0

Additionally, the following configurations have been added to the AndroidManifest.xml file:

<meta-data android:name="com.transistorsoft.locationmanager.license" android:value="our_key" />
<service android:name="com.transistorsoft.locationmanager.service.TrackingService" android:foregroundServiceType="location" android:exported="false" />
<service android:name="com.transistorsoft.locationmanager.service.LocationRequestService" android:foregroundServiceType="location" android:exported="false" />
<uses-permission android:minSdkVersion="34" android:name="android.permission.FOREGROUND_SERVICE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Application Overview (CDP EAS):
My application leverages flutter_background_geolocation 4.16.6 for consistently tracking user location in the background. This functionality ensures accurate activity tracking and precise distance calculations for users.

Issues Encountered:

1. Slow Execution and ANR During Registration:

   • When location permissions are granted on the Android device, the registration process (via RegisterHeadlessTask) takes a significantly long time to execute and respond.
   • Additionally, during execution, the application encounters ANR (App Not Responding) errors.
   • Note: Within the RegisterHeadlessTask specifically, tasks related to latitude and longitude processing are being performed.

2. Functionality Despite Denied Location Permissions:

   • After successful registration on RegisterHeadlessTask, the application continues to function properly, even when location permissions are subsequently denied.
