[Android article]android 4.4 SMS adaptation

Andorid 4.4 (KITKAT) has made changes to many aspects of the system, in the current project, the text has a direct impact. Let's take a look at the following document description:

Advice for SMS backup & Restore Apps

Because the ability to write to the Smsprovider are restricted to the app the user selects as the default SMS app, Anyexist ing app designed purely to backup and restore SMS messages would currentlybe unable to restore SMS messages on Android 4.4. An app, backs up andrestores SMS messages must also is set as the default SMS app so that it canwrite messages in the SMS Provider.

Therefore, we need to do a corresponding adaptation of 4.4

• In a broadcast receiver, include an intent filter for SMS_DELIVER_ACTION ( "android.provider.Telephony.SMS_DELIVER" ). The broadcast receiver must also require the BROADCAST_SMS permission.

  This allows your app to directly receive incoming SMS messages.

public class Smsreceiver extends Broadcastreceiver {@Override public void onreceive (context context, Intent Intent) {        Bundle extras = Intent.getextras ();        if (extras = = null) {return;        } object[] Smsextras = (object[]) extras.get ("PDUs");        if (Smsextras = = NULL | | smsextras.length = = 0) {return; } contentresolver Contentresolver = Context.getcontentresolver (); for (Object Smsextra:smsextras) {try {byte[] smsbytes = (byte[]) Smsextra; Smsmessage smsmessage = SMSMESSAGE.CREATEFROMPDU (smsbytes); Contentvalues values = new Contentvalues (); Values.put (Sms.address, smsmessage.getoriginatingaddress ()); Values.put ( Sms.body, Smsmessage.getmessagebody ()); Values.put (Sms.date, Smsmessage.gettimestampmillis ()); Values.put (Sms.READ , 0); Values.put (Sms.type, Sms.message_type_inbox); Contentresolver.insert (Uri.parse ("content://sms"), values);}    catch (Exception e) {e.printstacktrace ();}} }}

• In a broadcast receiver, include an intent filter for WAP_PUSH_DELIVER_ACTION ( "android.provider.Telephony.WAP_PUSH_DELIVER" ) with the MIME type "application/vnd.wap.mms-message" . The broadcast receiver must also require the BROADCAST_WAP_PUSH permission.

  This allows your app to directly receive incoming MMS messages.

public class Mmsreceiver extends Broadcastreceiver {@Overridepublic void OnReceive (context context, Intent Intent) {//TOD O}}

MMS does not use much in daily life, does not do the corresponding treatment

• In your activity this delivers new messages, include an intent filter for ACTION_SENDTO ( "android.intent.action.SENDTO" ) with schemas, sms: , smsto: , mms: , and mmsto: .

  This allows your app-to-receive intents from the other apps, the want to deliver a message.

public class Composesmsactivity extends Activity {}

• In a service, include an intent filter for ACTION_RESPONSE_VIA_MESSAGE ( "android.intent.action.RESPOND_VIA_MESSAGE" ) with schemas,,,, and sms: smsto: mms: mmsto: . This service must also require the SEND_RESPOND_VIA_MESSAGE permission.

  This allows users and respond to incoming phone calls with an immediate text message using your app.

public class Headlesssmssendservice extends Intentservice {public headlesssmssendservice () {Super (headlesssmssends        Ervice.class.getName ());    Setintentredelivery (TRUE);        } @Override protected void Onhandleintent (Intent Intent) {String action = intent.getaction (); if (!        TelephonyManager.ACTION_RESPOND_VIA_MESSAGE.equals (ACTION)) {return;        } Bundle Extras = Intent.getextras ();        if (extras = = null) {return;        } String message = Extras.getstring (Intent.extra_text);        Uri Intenturi = Intent.getdata ();        String recipients = getrecipients (Intenturi);        if (textutils.isempty (recipients)) {return;        } if (Textutils.isempty (message)) {return;        } string[] Destinations = textutils.split (recipients, ";");    Sendandstoretextmessage (Getcontentresolver (), destinations, message); }/** * Get quick response recipients from URI */PRivate string getrecipients (Uri uri) {string base = Uri.getschemespecificpart ();        int pos = Base.indexof ('? '); return (pos = =-1)?    Base:base.substring (0, POS); }/** * Send text message to recipients and store the message to SMS Content Provider * * @param contentres Olver Contentresolver * @param destinations recipients of message * @param message message */private void Sendandstoretextmessage (Contentresolver contentresolver, string[] destinations, String message) {Smsmanager SmsMan        Ager = Smsmanager.getdefault (); for (String destination:destinations) {try{smsmanager.sendtextmessage (destination, NULL, message, NU            ll, NULL);            Contentvalues values = new Contentvalues ();            Values.put (sms.address, destination); Values.put (sms.body, message); Values.put (Sms.date, System.currenttimemillis ()); Values.put (sms.read, 0); values.put            (Sms.type, sms.message_type_sent); COntentresolver.insert (Uri.parse ("content://sms"), values);        }catch (Exception e) {e.printstacktrace (); }        }    }}
