Neither user 10102 nor current process has android.permission.READ_PHONE_STATE

Question

I am trying to call getCallCapablePhoneAccounts() method of android.telecom.TelecomManager class. Though i have added required user-permission, i am getting Security exception.

Here is the line of code where i am getting exception

List<PhoneAccountHandle> list = getTelecomManager().getCallCapablePhoneAccounts();

user permission added in manifest

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

Exception stacktrace Caused by: java.lang.SecurityException: getDefaultOutgoingPhoneAccount: Neither user 10102 nor current process has android.permission.READ_PHONE_STATE. at android.os.Parcel.readException(Parcel.java:1599) at android.os.Parcel.readException(Parcel.java:1552) at com.android.internal.telecom.ITelecomService$Stub$Proxy.getDefaultOutgoingPhoneAccount(ITelecomService.java:615) at android.telecom.TelecomManager.getDefaultOutgoingPhoneAccount(TelecomManager.java:439)

Answer 1

On Android >=6.0, We have to request permission runtime.

Step1: add in AndroidManifest.xml file

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Step2: Request permission.

int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);

if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE);
} else {
    //TODO
}

Step3: Handle callback when you request permission.

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_READ_PHONE_STATE:
            if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                //TODO
            }
            break;

        default:
            break;
    }
}

Are you running Android M? If so, this is because it's not enough to declare permissions in the manifest. For some permissions, you have to explicitly ask user in the runtime: http://developer.android.com/training/permissions/requesting.html
