I am building a call forwarding application and have used the **21*xxxxxx# ussd code to activate call fowarding using ACTION_CALL Intent. But I have not found a solution to check whether Call forwarding is active or not.

是否有任何解决方案可以从android系统检查呼叫转移是否处于活动状态?

Is there any solution to check from the android system if call forwarding is active or not?

推荐答案

您可以让Brodcast类对其进行注册，并且可以跟踪呼叫

you can make Brodcast class register it and you can track out going call like

public class CallBroadcastReceiver extends BroadcastReceiver
{
    public static String numberToCall;
    public void onReceive(Context context, Intent intent) {
        Log.d("CallRecorder", "CallBroadcastReceiver::onReceive got Intent: " + intent.toString());
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
            numberToCall = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.d("CallRecorder", "CallBroadcastReceiver intent has EXTRA_PHONE_NUMBER: " + numberToCall);
        }

    }
}
