RxPermissionsResult

Following the same approach that RxActivityResult does, RxPermissionsResult is a reactive wrapper around the permission's Android Api, which allows to get the data without breaking the observable chain.

Features:

• Request permissions at runtime from any class, as long as you supply a valid Activity or Fragment instance.
• Get the data back encapsulated in an observable and keep chaining.
• Survive to configuration changes.

SetUp

Add to top level gradle.build file

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

Add to app module gradle.build file

dependencies {
	//RxJava1
    compile 'com.github.VictorAlbertos.RxPermissionsResult:rx1:0.0.4'
    compile 'io.reactivex:rxjava:1.2.1'

	//RxJava2
    compile 'com.github.VictorAlbertos.RxPermissionsResult:rx2:0.0.4'
    compile 'io.reactivex.rxjava2:rxjava:2.0.0'
}

Usage

Call RxPermissionsResult.register in your Android Application.

public class SampleApp extends Application {

    @Override public void onCreate() {
        super.onCreate();
        RxPermissionsResult.register(this);
    }
}

You can call RxPermissionsResult.on(this).requestPermissions(permissions) supplying both, an Activity instance or a Fragment instance.

Limitation:: Your fragments need to extend from android.support.v4.app.Fragment instead of android.app.Fragment, otherwise they won't be notified.

String[] permissions = {Manifest.permission.ACCESS_FINE_LOCATION};

RxPermissionsResult.on(this).requestPermissions(permissions)
  .subscribe(result ->
      result.targetUI()
          .showPermissionStatus(result.permissions(), result.grantResults())
  );

void showPermissionStatus(String[] permissions, int[] grantResults) {
    boolean granted = grantResults[0] == PackageManager.PERMISSION_GRANTED;
    if (granted) {
		textView.setText(permissions[0] + " Granted")
	} else {
		textView.setText(permissions[0] + "Not granted")
	}
}

Please pay attention to the targetUI() method in the Result object emitted.

This method returns a safety instance of the current Activity/Fragment. Because the original one may be recreated (due to configuration changes or some other system events) it would be unsafe calling it.

Instead, you must call any method/variable of your Activity/Fragment from this instance encapsulated in the Result object.

For a complete example about RxPermissionsResult, refer to this module if you are using RxJava1, or to this other one if using RxJava2.
