• User had to accept all permissions

• Declare permissions in AndroidManifest.xml

Permissions in SDK 23

• Activation during runtime

• Request dialog will not launch automatically

• User is also able to revoke the granted permission

Android M perimission flowchart

final private int REQUEST_CODE_ASK_PERMISSIONS = 123;

if (ContextCompat.checkSelfPermission(thisActivity,Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { // Should we show an explanation? if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, Manifest.permission.READ_CONTACTS)) { // Show an expanation to the user *asynchronously* -- don't block // this thread waiting for the user's response! After the user // sees the explanation, try again to request the permission. } else { // No explanation needed, we can request the permission. ActivityCompat.requestPermissions(thisActivity, new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_CODE_ASK_PERMISSIONS);

// REQUEST_CODE_ASK_PERMISSIONS is an // app-defined int constant. The callback method gets the // result of the request. } }

Show request rationale

Heandle permission request • @Override

public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case MY_PERMISSIONS_REQUEST_READ_CONTACTS: { // If request is cancelled, the result arrays are empty. if (grantResults.length > 0 && grantResults[0]==PackageManager.PERMISSION_GRANTED) { // permission was granted, yay! Do the // contacts-related task you need to do. } else { // permission denied, boo! Disable the // functionality that depends on this permission. } return; } // other 'case' lines to check for other // permissions this app might request } }

Permissions Best Practices

• Consider Using an Intent

• Only Ask for Permissions You Need

• Don't Overwhelm the User

• Explain Why You Need Permissions

• Test for Both Permissions Models

•Put the code in some util class

3rd party Libriaries

• EasyPermissions Link

• PermissionHelper Link (Educating UI) that explains why you need to use that particular permission.

• RxPermissions (for RxJava) Link asynchronous and event-based programs

• Let Link Aspect-oriented handler for new Android runtime permission model
