Hi I am new to android and jetpack compose. I have a class 'PermissionHandler' to handle the permission request for android app. It is extended by 'AppCompatActivity' class. I am able to request permission. But the overridden func 'onRequestPermissionsResult' is not called when the options are selected.
Below is the class>>
class PermissionHandler(context: Activity): AppCompatActivity(){
private val context: Activity = context
private lateinit var permissionClass: String
private lateinit var alertBody: String
private lateinit var toastMessage: String
companion object {
const val PERMISSION_REQ_CODE = 100
}
private fun checkPermission(): Boolean{
return (ContextCompat.checkSelfPermission(context, permissionClass) == PackageManager.PERMISSION_GRANTED)
}
private fun checkPermissionRationale(): Boolean{
return ActivityCompat.shouldShowRequestPermissionRationale(context, permissionClass)
}
private fun requestPermission(){
ActivityCompat.requestPermissions(context, arrayOf(permissionClass), PERMISSION_REQ_CODE )
}
@Composable
fun ShowPermissionExplanation(){
val alertInput = remember { mutableStateOf(false) }
if(!alertInput.value) {
AlertExplanation(
title = "Permission Needed",
body = alertBody
) { value -> alertInput.value = value }
} else {
requestPermission()
}
}
@Composable
fun CheckAndReqPermission(
permissionName: String,
permissionValue: (Boolean) -> Unit
){
permissionClass = permissionName
alertBody = "The app requires ${permissionClass.split('.')[2]} permission for particular feature to work as expected"
toastMessage = "Please allow ${permissionClass.split('.')[2]} permission to the APP."
if(checkPermission()){
permissionValue(true)
} else if (checkPermissionRationale()){
ShowPermissionExplanation()
}else{
requestPermission()
Toast.makeText(context, toastMessage, Toast.LENGTH_SHORT).show()
permissionValue(false)
}
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
Log.d("permission result", grantResults.toString())
Log.d("permission result", "checking Log if the callback is happedning or not")
}
}
The class object is simply called from a compossable func>>
@Composable
fun CheckBluetoothPermission(context: Activity) {
val permissionValue = remember{ mutableStateOf(false) }
val permissionHandler = PermissionHandler(context = context)
permissionHandler.CheckAndReqPermission(AppPermission.ACCESS_FINE_LOCATION.permission) { value ->
permissionValue.value = value
}
I want the callback func 'onRequestPermissionsResult' to be triggered when the user selects any of the below option>>
