[@nativescript/geolocation] - Error: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference

[jeanpaulattard]

The following exception is being thrown whenever I call the enableLocationRequest() method.

 Error: Uncaught (in promise): Error: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference

In the ngOnInit of my component, I'm calling the following piece of code

import { enableLocationRequest, isEnabled } from '@nativescript/geolocation';

...

isEnabled().then((enabled: boolean) => {
    if (!enabled) {
        return enableLocationRequest(true, true);
    }
});

This is happening on Android 11. Below are my gradle files and the permissions I have in the AndroidManifest.xml

android {
  defaultConfig {
    minSdkVersion 22
    generatedDensities = []
  }
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
}

    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Am I missing something? This is happening every time that method is called, and according to the docs that's all that is required to request location. Thanks in advance.

Any soution? I ran into the same issue

[Cersin]

• anybody?

[yencolon]

@Cersin be sure the permissions are in the manifest file and check this known issue (check the bottom of the page). That helped me.

[Cersin]

@yencolon still not working, i got all permission in manifest.
Same on ionic with geolocation works...

[Cersin]

@yencolon i have this error:
JS: Error: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.app.Activity.shouldShowRequestPermissionRationale(java.lang.String)' on a null object reference

@jeanpaulattard, @Cersin
The plugin versions 7.2.1 and 7.2.2 were thrown the same error on Android. Downgrading to the previous version that I was using (7.0.0 in my case) has worked for now. I haven't tried the versions between them

[canmertc]

Upgraded the plugin to v8.0.1. But still throws the same error

JS: Error: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.app.Activity.shouldShowRequestPermissionRationale(java.lang.String)' on a null object reference

Workaround:
Checking if there is a foreground activity on Android, before requesting the location has cleared the error.

if (isAndroid && !Application.android.foregroundActivity) {
    return
}
geolocation.enableLocationRequest();
