[Android Note] on the dial-up interface, you can call a specified number to start a secret interface.
Solution Description: 1. listen to the user's call operations by registering a broadcast receiver; 2. when a user makes a call, the broadcast receiver receives the number and compares it with the specified "dark". If the number matches, an interface is started and the user's call is terminated.
Implementation:

1. Configure the broadcast receiver in the configuration file and add permissions:

<receiver             android:name="cn.edu.chd.mobilesafe.receiver.CallPhoneReceiver"            >            <intent-filter                 android:priority="1000"                >                <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>            </intent-filter>        </receiver>  

Permission:

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

2. process in the OnReceive method of the broadcast receiver:

Public class CallPhoneReceiver extends BroadcastReceiver {private static final String CODE = "110"; @ Override public void onReceive (Context context, Intent intent) {String number = getResultData (); if (CODE. equals (number) {Intent myIntent = new Intent (context, DemoActivity. class); myIntent. addFlags (Intent. FLAG_ACTIVITY_NEW_TASK); context. startActivity (myIntent); // terminate the outbound call setResultData (null );}}}
