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:

        return eventID;

    }
}

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.

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) {...}

already give runtime both permission then also throw error permission denial — Makvin, Jun 27 '19 at 05:49
Thanks Gabriel! For those who stumble across this answer in the future please keep in mind that onRequestPermissionsResult is now deprecated. See this [SO answer](https://stackoverflow.com/a/66552678/848353) for the current method that will need to be adapted for Calendar permissions. — yerty, Jun 11 '21 at 13:34
