Background knowledge: when Android starts, it emits a system broadcast with the content action_boot_completed,Its string constant is represented as Android.intent.action.BOOT_COMPLETED. just "snap" to this message in the program and start it again .。 Remember, the Android framework says, "Don ' t call me, I'll be back." What we have to do is prepare to receive the message, and the means to achieve it is to achieve a broadcastreceiver.
Code parsing:
1. Interface Activity:SayHello.java
 PackageCom.ghstudio.BootStartDemo; Importandroid.app.Activity; ImportAndroid.os.Bundle; ImportAndroid.widget.TextView;  Public classSayHelloextendsActivity {@Override Public voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate); TextView TV=NewTextView ( This); Tv.settext ("Hello." I started! ");      Setcontentview (TV); }  }  
This code is simple, when the activity starts, create a textview and use it to display "Hello." I started! " Words.
2. Receive broadcast message: Bootbroadcastreceiver.java
 PackageCom.ghstudio.BootStartDemo; ImportAndroid.content.BroadcastReceiver; ImportAndroid.content.Context; Importandroid.content.Intent;  Public classBootbroadcastreceiverextendsBroadcastreceiver {Static FinalString ACTION = "Android.intent.action.BOOT_COMPLETED"; @Override Public voidOnReceive (Context context, Intent Intent) {if(Intent.getaction (). Equals (ACTION)) {Intent sayhellointent=NewIntent (Context,sayhello.class);       Sayhellointent.addflags (Intent.flag_activity_new_task);    Context.startactivity (sayhellointent); }   }    }  
The class derives from the Broadcastreceiver, and in the method OnReceive, detects whether the received intent conforms to the boot_completed and, if so, initiates the SayHello activity.
3. configuration file: Androidmanifest.xml
<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android= "Http://schemas.android.com/apk/res/android" Package= "Com.ghstudio.BootStartDemo"Android:versioncode= "1"Android:versionname= "1.0" > <application android:icon= "@drawable/icon" android:label= "@string/app_name" > <activity A Ndroid:name= ". SayHello "Android:label= "@string/app_name" > <intent-filter> <action android:name= "android.intent.action . MAIN "/> <category android:name=" Android.intent.category.LAUNCHER "/> </intent-f ilter> </activity> <receiver android:name= ". Bootbroadcastreceiver "> <intent-filter> <action android:name=" Android.intent.action.BOOT_COMPLETED "/&     Gt       </intent-filter> </receiver> </application> <uses-sdk android:minsdkversion= "3"/> <uses-permission android:name= "Android.permission.RECEIVE_BOOT_COMPLETED" ></uses-permission> </ Manifest>
Note that in the bolded part, the node registers a receiver with the system, and the child node Intent-filter represents the receiving Android.intent.action.BOOT_COMPLETED message. Don't forget to configure Android.permission.RECEIVE_BOOT_COMPLETED permissions.


===========================================

1. To do is to listen to the system issued by the broadcast

 Public class extends broadcastreceiver{        publicvoid  onreceive (context context, Intent Intent) {                 if(Intent.ACTION_BOOT_COMPLETED.equals (Intent.getaction ())) {                        start (context);        }}}

2. Add receiver to the Androidmenifest.xml and indicate that the entrance to the program is Florencetest

    <application        android:icon= "@drawable/ic_launcher"        android:label= "@string/app_name ">        <receiver android:name=". Main. Florencetest "                android:exported=" true "                android:process=": Remote ">            < Intent-filter >                        <action android:name= "Android.intent.action.BOOT_COMPLETED"/>                        <category Android:name= "Android.intent.category.HOME"/>            </intent-filter>        </receiver>  </ Application>

This allows the program to run automatically at boot time.
