Android uses service to implement background send mail function instance _android

This article describes the use of service in Android to implement the background send mail function. Share to everyone for your reference, specific as follows:

The procedure is as follows:

Import android.app.Activity;
Import android.content.Intent;
Import android.content.res.Resources.NotFoundException;
Import Android.os.Bundle;
Import Android.widget.TextView;
 public class A05activity extends activity {private TextView TV;
 Private string[] receiver;
 Private String subject;
  Private String body; /** called the activity is a.
    * * @Override public void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Setcontentview (R.layout.main);
    tv= (TextView) Findviewbyid (r.id.tv);
    Tv.settext ("Waiting to receive mail");
  try {//Get SMS from Bundle Bundle b=this.getintent (). Getextras ();
  if (b!=null) {//Bundle string s=b.getstring ("input")
  Receiver=new string[]{"1650967185@163.com"};
  subject= "Mailbox Send";
  Body=s.tostring ();
  Customize a Intent industry to perform the work of sending e-mail Intent i=new Intent (Android.content.Intent.ACTION_SEND); I.settype ("Plain/text");//Set Message format to "Plain/text" I.putextra (Android.content.intent.extra_email,receiver);Into the recipient address I.putextra (Android.content.Intent.EXTRA_SUBJECT, SUBJECT);//Incoming message subject I.putextra (Android.content.Intent.EXTRA
  _text, body);//Incoming message content startactivity (Intent.createchooser (i, Getresources (). getString (R.string.message)));
  else{finish ();
 The catch (Notfoundexception e) {//TODO auto-generated catch block E.printstacktrace ();

 }
  }
}

Import Android.content.BroadcastReceiver;
Import Android.content.Context;
Import android.content.Intent;
Import Android.os.Bundle; Import android.telephony.gsm.smsmessage;//is used to receive SMS import android.widget.toast;//inform users to receive SMS @SuppressWarnings (" Deprecation ") public class ServiceA05 extends broadcastreceiver{public static final String maction=" Android.provider.Te
  Lephony.sms_received ";
 Private String str_receiver= "received SMS"; @Override public void OnReceive (context arg0, Intent arg1) {//TODO auto-generated Method Stub Toast.maketext (arg0, St
 R_receiver.tostring (), Toast.length_long). Show ();
  if (Arg1.getaction (). Equals (Maction)) {//construct a string Set variable SB StringBuilder sb=new StringBuilder ();
  Receive Data Bundle B=arg1.getextras (); Determine if the intent transfer data is null if (b!=null) {//pdus for Android built-in SMS parameters indentifier/* Returns an Object containing Bundle.get via PDUs ("") * * * object[]
  Myobjpuds= (object[]) b.get ("PDUs");
  Constructs the short message object array, and according to the text message content size to determine the array size smsmessage[] sm=new smsmessage[myobjpuds.length]; for (int I=0;I<MYOBJPUDS.Length;i++) {SM[I]=SMSMESSAGE.CREATEFROMPDU (byte[]) myobjpuds[i]);
   ///merge SMS with custom information in StringBuilder for (Smsmessage sm01:sm) {Sb.append ("received from: \ n");
   The telephone number of the addressee Sb.append (sm01.getdisplayoriginatingaddress ());
   Sb.append ("\ n--------message---------\ n");
   Obtain the content of the text message Sb.append (Sm01.getdisplaymessagebody ());
  Use Toast to display incoming call information Toast.maketext (arg0, sb.tostring (), Toast.length_long). Show ();
  } toast.maketext (arg0, sb.tostring (), Toast.length_long). Show ();
  Return to the main activity Intent i=new Intent (arg0,a05activity.class);
  Define a Bundle Bundle b01=new Bundle ();
  The text message is deposited in the bundle b01.putstring ("Input", sb.tostring ()) by the putstring () method;
  Put the bundle into the intent I.putextras (B01);
  Set the Intent FLAG to run I.setflags (Intent.flag_activity_new_task) with a new TASK;
 Arg0.startactivity (i);

 }
 }
}

The

Androidmanifest.xml is as follows:

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android= "http://schemas.android.com/apk/res/" Android "package=" Com.my.a05 "android:versioncode=" 1 "android:versionname=" 1.0 "> <uses-sdk android:minsdkve
    Rsion= "/>" <application android:icon= "@drawable/ic_launcher" android:label= "@string/app_name" > <activity android:name= ". A05activity "android:label=" @string/app_name "> <intent-filter> <action android:name=" Andr Oid.intent.action.MAIN "/> <category android:name=" Android.intent.category.LAUNCHER "/> </intent -filter> </activity> <receiver android:name= "ServiceA05" > <intent-filter> <a ction android:name= "Android.provider.Telephony.SMS_RECEIVED"/> </intent-filter> </receiver>
 ;/application> <uses-permission android:name= "Android.permission.RECEIVE_SMS"/> </manifest>

Register a broadcastreceiver in Android and set up this receiver Intent-filter (Android.provider.Telephony.SMS_RECEIVED), Let it respond to SMS events. And also add a permission: Android.permission.RECEIVE_SMS.
