Disconnect a call programatically not working in android 8.0(Oreo)

Question

Up to Android 7.1 it was possible to end an incoming call by using the ITelephony.endCall() method and giving your app the permissions android.permission.CALL_PHONE and android.permission.READ_PHONE_STATE.

When doing the same on Android 8.0 Oreo (API 26), i get this error

Here is the code for READ_PHONE_STATE run time permission.

String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.READ_PHONE_STATE,
        Manifest.permission.ANSWER_PHONE_CALLS};
void permissionCheck() {

    if (!hasPermissions(this, PERMISSIONS)) {
        ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
    }
}

public static boolean hasPermissions(Context context, String... permissions) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

Can anyone please help me ?

Looks like you relied on an undocumented method that you called through reflection. What you did was not intended to be done by the Android team, and they most likely just stuffed that security hole. — 323go, Dec 15 '17 at 13:48
@WaleedAsim updated the question with run time permission code. Please check. — Santosh, Dec 18 '17 at 08:23

Looks like you forgot adding runtime permission for CALL_PHONE Caused by: java.lang.SecurityException: Neither user 10304 nor current process has android.permission.CALL_PHONE.

Thank you for your answer. But I added String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.READ_PHONE_STATE}; if (!hasPermissions(this, PERMISSIONS)) { ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL); } – Santosh Dec 15 '17 at 13:54

One possible solution is via Android Accessibility Service. You can find the resource id of Cancel call button and Click that via 11y Service!

Check out this link which uses Android Accessibility Service to press "Force Stop" button just like Greenify App.

How to click button in settings using AccessibilityService?

Hope this helps!
