In debug, not receiving any location entries on physical device (Android Redmi Note 7, MIUI 12)

[torian257x]

I copied your example over along with the extra files and packages needed to fix all errors from https://github.com/rekab-app/background_locator/tree/master/example/lib

problem is that no entries appear in

Last run: ?

Status: is running

I thought maybe something is off with my gps / location settings but if I enable mock locations https://play.google.com/store/apps/details?id=ru.gavrikov.mocklocations&hl=en&gl=US I am able to see that my gps signal moves on a path (I check in google maps) no updates anyway

btw I feel like, to enable the request permission in debug, I had to change my debug manifest to this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.locatortest1">
    <!-- Flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.
    -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>

If I left it like you had in the example, it wouldn't receive permission for location updates I think. There would just be no popup to give permission. After updating this manifest, and running flutter clean and redeploy the app, the popup did come.

here is my output:

once I press stop I receive:

just doesn't seem to work.

solution could be for me to switch plugins - this one works after following the steps I outlined: https://github.com/Lyokone/flutterlocation/issues/502

notice: doing the same steps for the plugin of this repo, doesn't work.

This might be a permissions issue. If you go to Settings > Location > Give your app the 'Allow all the time' permission. You could reach the permissions by going through the App's settings page too.

Like I mentioned in #184, its possibly due to the permission request not working as desired.

I tried just doing that right now. Doesnt work either. I tried flipping it on and off a couple times (the service).
