Right way of requesting permissions for location coordinates in Android 10

Below code does not work on Android 10 until you manually enable the location from settings. When I go through the Android 10 documentation, it says if you are fetching location from the visible activity, if that was the case you don't need any foreground service, that's the reason I haven't used any service here.
And also as per Android 10 guidelines, after permission getting granted I am calling getLastLocation function.
Implementation is like, on main activity I am fetching location coordinates.
Please help, where in the code am I going wrong?

Well there is a problem. Official documentation states that it can be null in some cases
https://developer.android.com/training/location/retrieve-current
Location is turned off in the device settings. The result could be null even if the last location was previously retrieved because disabling location also clears the cache.
The device never recorded its location, which could be the case of a new device or a device that has been restored to factory settings.
Google Play services on the device has restarted, and there is no active Fused Location Provider client that has requested location after the services restarted. To avoid this situation you can create a new client and request location updates yourself. For more information, see Receiving Location Updates.
In your case you can get location only if GPS is ON. Even for last known location.
https://developer.android.com/training/location/retrieve-current#last-known

Please add this permission in AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
and add this to application tag
android:usesCleartextTraffic="true"

Am I missing something to get google maps to open from android webview

Iam new to the android programming environment and am creating my first app. I am trying to get webview to open google maps when a google maps link is clicked within webview. Am I missing something as to why this is still opening the link in webview and not executing google maps instead? And when it is opening in webview it shows the destination fine but it does not show my location and states it is unable to determine my location on the bottom of the page being displayed

Found the problem.
if( url.startsWith("http:") || url.startsWith("https:") ) {
was preventing google maps from opening as it was forcing any url with https to stay within the webview. modified it to
if( url.startsWith("http:")) {
and all is good now.

avoid of send null from destroyed activity to restarted service

I want to programing app for data track in background , so I use service .
I want to write a program that monitors all data sent and received by the device, and when the total volume of received or received messages reaches a specified value, the Internet device is turned off.
So I used the following code to monitor the data:
 
mStartRX = TrafficStats.getTotalRxBytes ();
mStartTX = TrafficStats.getTotalTxBytes ();
And I used the services to work on the background in the background.
To specify the download or upload limit from the user with edittext, I requested this limit in mainactivity and send this value to the service.
The problem is when: When I destroy the program, I will restart the service and get the NULL value and the program crashes.

please help me ...

The problem is with this line
public long dl=MainActivity.DLL;
You're referring to a variable in the Activity, surly when the Activity is destroyed, this variable is no longer in scope, thus you get Null Exception.
You must get this value using the intent.
The other problem is that you can't prevent any service from being killed by the system except foreground services which need to show a notification to the user. But this is not suitable for your situation.
Therefore, the best approach for you is to check whether intent is null or not. If it is not null, you get the value and save it into Preferences or Database or somewhere, if it is null, you retrieve the value from where you stored it before.

This code is not working. The service starting when the startService calling in MainActivity. But when a dialer open it not working.

I think maybe you can try changing getApplication () to MainActivity.this.
And I think you need to jump from the dialer to MainActivity to get the service started

Where am I wrong with broadcasting info from Java and receiving in Unity?

So I just started working on this project and part of it is sending packages of information from an app in Java to another Unity app.
I have been trying to follow this tutorial but I have problems getting it to work and even somewhat understanding it a bit since I have not worked with Java before.
