OverlayHelper

This utility library aims to help Android developers handle "draw overlays" (also called "draw over other apps") permissions and queries in a version-agnostic way.

Installation

Add the following dependencies to your main build.gradle:

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

Add the following dependencies to your app's build.gradle:

• For Gradle < 4.0

  dependencies {
      compile "com.github.adriangl:overlayhelper:1.1.0"
  }

• For Gradle 4.0+

  dependencies {
      implementation "com.github.adriangl:overlayhelper:1.1.0"
  }

Example usage

• Create a new OverlayHelper with a OverlayPermissionChangedListener.
• Start watching settings changes with OverlayHelper.startWatching(), for example in onCreate().
• Stop watching changes with OverlayHelper.stopWatching() in onDestroy().
• If you want to check if the app has their "draw overlays" permission enabled, use OverlayHelper.canDrawOverlays().
• Call OverlayHelper.requestDrawOverlaysPermission() wherever you want in your activity. You'll have to also add OverlayHelper.onRequestDrawOverlaysPermissionResult(int) in the activity's onActivityResult(), so the helper can retrieve the needed data.
• You'll receive your permission results in the OverlayPermissionChangedListener that you registered when creating the helper.

Check the example app for more implementation details.
