SMS short message service processing and contact acquisition method developed by Android API

This paper describes the method of SMS service processing and obtaining contacts developed by Android API. Share with you for your reference, as follows:

The Android API supports the development of applications that can send and receive SMS messages. At present, the Android simulator used in our development process does not support sending SMS, but it can receive SMS. Now let's explore Android's support for SMS. We will build a small application to listen to SMS messages received on mobile devices (or simulators) and display them. Let's define an intent receiver to handle SMS receiving events:

We need to configure the intent receiver so that it can get SMS receiving events, Android provider. Telephony. SMS_ Received this event status indicates that the SMS has been received. We can do it at Android manifest XML is configured as follows:

In order to enable our application to receive SMS, we must specify the permission first, which can be found in androidmanifest XML is configured as follows:

Now, our intent receiver can be called when the Android device receives the SMS. The rest is to obtain and display the received SMS message text:

The SMS received by the Android device is in the form of PDU (protocol description unit). android. telephony. gsm. The smsmessage class can store SMS related information. We can also create a new smsmessage instance from the received PDU. The toast interface component can display the received SMS message text in the form of system notification.

Running program:

Now let's run the application in the simulator and send SMS messages to the simulator. We can send SMS messages to the simulator in the DDMS view (Dalvik debug monitor service) provided by the Android plug-in of eclipse (in the 'emulator control' panel; in addition, we need to specify the phone number, but it can be arbitrary)

Method of issuing broadcast intent:

Need to write another broadcast receiver:

Get contact information:

In Android manifest Add in XML:
