Permissions

Easy Permissions Management Library for Android

An easy to use permissions management library written in Kotlin.

Import the Library

The library is deployed on JitPack here. To add it to your project, add to settings.gradle:

dependencyResolutionManagement {
  ...
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

And to your module level build.gradle:

dependencies {
  ...
  implementation 'com.github.lorenzofelletti:permissions:0.4.2'
}

Usage

To use the library in your project, just:

• Declare the permissions your app will use in your application's Manifest
  • Example: add to the app AndroidManifest.xml

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

• Create a PermissionManager in your Activity
  • Example: in your MainActivity

    private val permissionManager = PermissionManager(this)

• Decide a request code for each set of permissions that you will require simultaneously (each request code is a positive integer of your choice, but do not use the same code for different set of permissions)
  • Example: add to your MainActivity

  companion object {
        private const val POSITION_REQUEST_CODE = 1
        private val POSITION_REQUIRED_PERMISSIONS = arrayOf(
            android.Manifest.permission.ACCESS_FINE_LOCATION,
            android.Manifest.permission.ACCESS_COARSE_LOCATION
        )
    }

• Build the RequestResultsDispatcher
  • Example: in the MainActivity's onCreate function add

  permissionManager.buildRequestResultsDispatcher {
      withRequestCode(POSITION_REQUEST_CODE) {
          checkPermissions(POSITION_REQUIRED_PERMISSIONS)
          doOnGranted {
              Log.d(TAG, "Location permission granted") 
          }
          doOnDenied {
              Log.d(TAG, "Location permission denied")
          }
      }
  }

• Call permissionManager.checkRequestAndDispatch where you want to check for a set of permissions (and ask them if not granted)
  • Example: in your Activity, where you want to check (and request) permissions add

  permissionManager checkRequestAndDispatch POSITION_REQUEST_CODE

• Override onRequestPermissionsResult and call PermissionsUtilities.dispatchOnRequestPermissionsResult in it
  • Example: inside your MainActivity

  override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        permissionManager.dispatchOnRequestPermissionsResult(requestCode, grantResults)
    }
