Android targetSdkVersion 23 checkSelfPermission method

I am facing checking permission value in Android 6.0 (API 23). Always get 0 value even permission enable or disable from app's settings.

Below is step which I taken.

Contact permission manually disable from device

settings->apps-> My apps-> permission -> Disable contact permission

Still In Android 6.0 every time got 0 value when execute below line of code.

ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CONTACTS)

Below is my code. which I define in main launcher activity class

// Identifier for the permission request
private static final int WRITE_CONTACTS_PERMISSIONS_REQUEST = 9;

public void onCreate(Bundle savedInstanceState) {
if (android.os.Build.VERSION.SDK_INT <= android.os.Build.VERSION_CODES.LOLLIPOP_MR1)
sharedPreferencesEditor.putBoolean(getString(R.string.ALLOW_ACCESS_PHONEBOOK), true);
else {


// Called when the user is performing an action which requires the app to read the
// user's contacts
public void getPermissionToReadUserContacts() {
// 1) Use the support library version ContextCompat.checkSelfPermission(...) to avoid
// checking the build version since Context.checkSelfPermission(...) is only available
// in Marshmallow
// 2) Always check for permission (even if permission has already been granted)
// since the user can revoke permissions at any time through Settings
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {

// The permission is NOT already granted.
// Check if the user has been asked about this permission already and denied
// it. If so, we want to give more explanation about why the permission is needed.
if (shouldShowRequestPermissionRationale(
Manifest.permission.WRITE_CONTACTS)) {
// Show our own UI to explain to the user why we need to read the contacts
// before actually requesting the permission and showing the default UI

// Fire off an async request to actually get the permission
// This will show the standard permission request dialog UI
requestPermissions(new String[]{Manifest.permission.WRITE_CONTACTS},

// Callback with the request from calling requestPermissions(...)
public void onRequestPermissionsResult(int requestCode,
@NonNull String permissions[],
@NonNull int[] grantResults) {
// Make sure it's our original READ_CONTACTS request
if (grantResults.length == 1 &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Write Contacts permission granted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Write Contacts permission denied", Toast.LENGTH_SHORT).show();
} else {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);

Answer Source

If you target SDK 23 (Android 6), all of the permissions (in your manifest) are disabled by default, whereas if your targetSDK is 22 (Android 5.1) and your app is running on Android 6, all of the permissions are enabled by default when the user installs the app, and even if the user revokes the permissions later on, checkSelfPermission returns incorrect value of PERMISSION_GRANTED

It is also available in the documentation of PermissionChecker

In the new permission model permissions with protection level dangerous are runtime permissions. For apps targeting M and above the user may not grant such permissions or revoke them at any time. For apps targeting API lower than M these permissions are always granted as such apps do not expect permission revocations and would crash. Therefore, when the user disables a permission for a legacy app in the UI the platform disables the APIs guarded by this permission making them a no-op which is doing nothing or returning an empty result or default error.
