Nativescript Android 8.0 READ_CALL_LOG Failed - nativescript

Question

Using Nativescript 5.0.
Below piece of code works well in Android ver 6.0.1
But fails to get permission in Android 8.0
Permission seeking message box does not appear.
Difference observed in both phone's permission details is, in Android 8.0, additional permission is seen as "Dial through contacts" which can not be set manually.
Permissions.requestPermission(android.Manifest.permission.READ_CALL_LOG, "Needed for connectivity status").then(() => {
console.log("refresh - Permission granted!");
this.readCallLog();
alert("in refresh Permission granted");
}).catch(() => {
console.log("Permission is not granted (sadface)");
alert("in refresh Permission NOT granted");
});

Answer 1

Try including READ_PHONE_STATE permission.
But to be precise nothing was changed in Android 8, but Android 9 introduced breaking changes to read call log permission which now requires phone state permission too to work.

Answer 2

While with earlier Android versions you could just request permission READ_CALL_LOG the newer Android versions are introducing some changes in how you could request the user call logs. The idea is to provide more information to the user explaining why you need these permissions.
An explanatory strings values should be provided in the Andorid resources
<string name="permgroupdesc_calllog">read and write phone call log</string>
<string name="permgrouprequest_calllog">Allow <b>%1$s</b> to access your phone call logs?</string>
Also, you will need to ask for a number of permissions and not just READ_CALL_LOG:
CALL_LOG
READ_CALL_LOG
WRITE_CALL_LOG
ROCESS_OUTGOING_CALLS
