android permissions READ_CALENDAR & WRITE_CALENDAR

Question

even though i have declared the uses-permissions in the manifest, it gives me an error saying i need to add the permissions.

android manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="groep2.project4">
    <uses-permission android:name="android.permission.READ_CALENDAR"/>
    <uses-permission android:name="android.permission.WRITE_CALENDAR"/>
    <uses-permission-sdk-23 android:name="android.permission.READ_CALENDAR"/>
    <uses-permission-sdk-23 android:name="android.permission.WRITE_CALENDAR"/>

error:

    }
}

i cant figure out why it doesn't work. ive even tried adding the other SDK version of the permission but it still didn't work.

Answer 1

Once you are targeting android SDK 23 you should work with RunTime permissions, below is a simple method to help you on getting started.

private void checkPermissions(int callbackId, String... permissionsId) {
    boolean permissions = true;
    for (String p : permissionsId) {
        permissions = permissions && ContextCompat.checkSelfPermission(this, p) == PERMISSION_GRANTED;
    }

    if (!permissions)
        ActivityCompat.requestPermissions(this, permissionsId, callbackId);
}

You can use it like this:

 final int callbackId = 42;
 checkPermission(callbackId, Manifest.permission.READ_CALENDAR, Manifest.permission.WRITE_CALENDAR);

The requestPermissions method returns a callback in witch you can proceed to deal with the permissions being denied or accepted:

@Override
public void onRequestPermissionsResult(int callbackId,
        String permissions[], int[] grantResults) {...}
