A lightweight Android library which wraps boilerplate code of runtime permission and allows you to request permissions
- from coroutines. (No callbacks yay 🎉)
- request and observe permissions through LiveData.
- through clean and concise Kotlin DSL.
From release
2.0.0onwards library is migrated to AndroidX. If you are still using support library and haven't migrated to AndroidX then check out non-androidX version of the library.
Eazy permissions is available in the Jcenter and divided into three modules so that based on your need you can include either coroutines or livedata or Kotlin DSL support in your project
//For coroutines
implementation 'com.sagar:coroutinespermission:[latest_version]'
//For LiveData
implementation 'com.sagar:livedatapermission:[latest_version]'
//For Kotlin DSL
implementation 'com.sagar:dslpermission:[latest_version]'latest_versionfor coroutines -latest_versionfor livedata -latest_versionfor Kotlin DSL -
This is how you would request permission within coroutines.

launch {
//CoroutineScope
val permissionResult = PermissionManager.requestPermissions( //Suspends the coroutine
this@Fragment,
REQUEST_ID,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.READ_CONTACTS,
Manifest.permission.CAMERA
)
//Resume coroutine once result is ready
when(permissionResult) {
is PermissionResult.PermissionGranted -> {
//Add your logic here after user grants permission(s)
}
is PermissionResult.PermissionDenied -> {
//Add your logic to handle permission denial
}
is PermissionResult.PermissionDeniedPermanently -> {
//Add your logic here if user denied permission(s) permanently.
//Ideally you should ask user to manually go to settings and enable permission(s)
}
is PermissionResult.ShowRational -> {
//If user denied permission frequently then she/he is not clear about why you are asking this permission.
//This is your chance to explain them why you need permission.
}
}

requestPermissions(

Manifest.permission.READ_CONTACTS,
Manifest.permission.CAMERA
) {
requestCode = 4
resultCallback = {
when(this) {
is PermissionResult.PermissionGranted -> {
//Add your logic here after user grants permission(s)

//Add your logic to handle permission denial

This is how you would request permission within Acivity/Fragment.
PermissionManager.requestPermissions(
this,
REQUEST_ID,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.READ_CONTACTS
)Observing permission result requires your Actvity/Fragment to implement PermissionObserver
/**
* Interface definition for a callback to get [LiveData] of [PermissionResult]
*
* Implement this interface to get [LiveData] for observing permission request result.
*/
interface PermissionObserver {
fun setupObserver(permissionResultLiveData: LiveData<PermissionResult>)
}Just as you would observe other LiveData you can observe LiveData<PermissionResult> as follow.
override fun setupObserver(permissionResultLiveData: LiveData<PermissionResult>) {
permissionResultLiveData.observe(this, Observer<PermissionResult> {
when (it) {
is PermissionResult.PermissionGranted -> {
if (it.requestId == REQUEST_ID) {
//Add your logic here after user grants permission(s)
}
}
is PermissionResult.PermissionDenied -> {
if (it.requestId == REQUEST_ID) {
//Add your logic to handle permission denial
}
}
is PermissionResult.PermissionDeniedPermanently -> {
if (it.requestId == REQUEST_ID) {
//Add your logic here if user denied permission(s) permanently.
//Ideally you should ask user to manually go to settings and enable permission(s)
}
}
is PermissionResult.ShowRational -> {
if (it.requestId == REQUEST_ID) {
//If user denied permission frequently then she/he is not clear about why you are asking this permission.
//This is your chance to explain them why you need permission.
}
}
}
})
