[Android] mobile guard blacklist function (SMS interception), android guard

Previously, we stored and displayed all the mobile phone numbers to be intercepted. Next, we used the broadcast receiver to intercept text messages. This broadcast receiver needs to be bound to a service. when the service is enabled, the receiver exists, when the service is stopped, the receiver closes

 

Define a class CallSmsSafeService under the service package to inherit the system's Service

Override the onCreate () method

Obtain the BroadcastReceiver object.

Call the registerReceiver () method to register the broadcast. parameters: BroadcastReceiver object and IntentFillter object

 

 

Override onDestory () method

Call the unregisterReceiver () method. Parameter: BroadcastReceiver object

The BroadcastReceiver object is set to null.

 

Defines an InnerSmsReceiver class that inherits the BroadcastReceiver of the system.

Override the onReceive () method and pass in parameters: Context object, Intent object

Call the getExtras (). get ("pdus") method of the Intent Object to obtain the Object [] array.

For Loop Object [] array, each of which is an Object

Call the SmsMessage. createFromPdu () method to obtain the SmsMessage Object. The parameter is an array of byte [] and is strongly converted to an Object.

Call the getOriginatingAddress () method of the SmsMessage object to obtain the String sender.

Call the database query method of the Dao object to find the interception mode of this text message.

Determine the interception mode. If all requests are intercepted 3 or 2, call the abortBroadcast () method.

 

 

Configure the service in the configuration center to enable and disable the service.
