Android(6.*) : Permission denial although permissions are assigned, and are not requested

Question

I am working on an Android project in which I am displaying the contacts. I have added contacts permission in android, still I kept getting error for the app. I am trying out the app on Marshmallow and it didn't even ask me for permission, but I went in apps, selected permissions and enabled contacts. After that, the app was not crashing anymore, But I am still getting an error.

ANdroidManifest.xml :

<uses-permission android:name="android.permission.READ_CONTACTS"/>
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
    <uses-permission android:name="android.permission.read_contacts" />
    <uses-permission android:name="android.permission.read_phone_state" />
    <uses-permission android:name="android.permission.READ_CALL_LOG" />

Error log :

Can you tell me what does REQUEST_RUNTIME_PERMISSION = 123; mean? What's it for? For network operations? — We are Borg, Sep 01 '16 at 11:34
its identifier for used for different permission against it ...like your are getting set of other permissions and want to do some tasks against every single of them then this identifier will you let you know which set of permission is trigger by user. — Sohail Zahid, Sep 01 '16 at 11:40

The Android will not ask for permission itself, You have to add code to

ask the user everytime to check whether the required permissions are

available or not and act accordingly.

I just checked the link, and when I add the checkSelfPermission, I get an error call requires Api level 23, min is 16. – We are Borg Sep 01 '16 at 11:12
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) you have to add your permission check inside this – Ashish Shukla Sep 01 '16 at 11:17

The problem is that in Android 6.0 (API level 23) you must check permissions at runtime. You can find more info here.

Refer this for a better understanding.

Since Android 6, (targetSdkVersion >=23 in your build.gradle file) you need to explicitly request for those permissions that are dangerous.

To check for permissions you should use ContextCompat.checkSelfPermission(). To request for permission you should useActivityCompat.requestPermissions().

More info here.

Check here for the list of normal/dangerous permissions.

You should first have to check READ_CONTACTS permission. Here is the code to check the permission.

   public boolean checkPermissionForReadContacts() {
      int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.READ_CONTACTS);
   if (result == PackageManager.PERMISSION_GRANTED) {
        return true;
    } else {
        return false;
    }
   }

This might help!

If the permission is not granted then display an alert of permission request. Try out this library for permissions it will handle everything: https://github.com/Karumi/Dexter – Abdullah Mehmood Sep 01 '16 at 11:19
