Android Permission Launcher

Easily request permission with new Launcher API and recommended rationale checks like shouldShowRequestPermissionRationale. All with a simple lightweight class and one liner code. It's basically a wrapper class around Activity Result API with Rationale Dialog shown to the user.

Installation

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
    implementation "com.github.kevintorch:PermissionLauncher:1.1.0"
}

Usage

class MainActivity : AppCompatActivity() {
    // just add a field in Activity or fragment. 
    private val permissionLauncher = PermissionLauncher(this, ::onPermissionGranted)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // then request permission
        permissionLauncher.launch(Manifest.permission.CAMERA)
    }

    private fun onPermissionGranted() {
        // Do Something if Permission Granted.
    }
}

Extra Features

permissionLauncher.setEnableRationale(false)   // default is true.

// or

permissionLauncher.setEnableRationale(true, "Your Cuatom Rationale Message.")

Note

Requires sdk >= 21
