How to enable auto-start on Android

Compiling the Android operating system in the simulator can help us implement the auto-start function of the application at startup. Here, we will use a piece of code to fully master the implementation of Android boot auto-start, to help you master this application.

1. Define a BroadcastReceiver

Java code

 
 

  
  
public class BootReceiver extends BroadcastReceiver {   
  
  
public void onReceive(Context ctx, Intent intent) {   
  
  
Log.d("BootReceiver", "system boot completed");   
  
  
//start activity   
  
  
String action="android.intent.action.MAIN";   
  
  
String category="android.intent.category.LAUNCHER";   
  
  
Intent myi=new Intent(ctx,CustomDialog.class);   
  
  
myi.setAction(action);   
  
  
myi.addCategory(category);   
  
  
myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   
  
  
ctx.startActivity(myi);   
  
  
//start service   
  
  
Intent s=new Intent(ctx,MyService.class);   
  
  
ctx.startService(s);   
  
  
}   
  
  
}   
  
  
public class BootReceiver extends BroadcastReceiver {  
  
  
public void onReceive(Context ctx, Intent intent) {  
  
  
Log.d("BootReceiver", "system boot completed");  
  
  
//start activity  
  
  
String action="android.intent.action.MAIN";  
  
  
String category="android.intent.category.LAUNCHER";  
  
  
Intent myi=new Intent(ctx,CustomDialog.class);  
  
  
myi.setAction(action);  
  
  
myi.addCategory(category);  
  
  
myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
  
  
ctx.startActivity(myi);  
  
  
//start service  
  
  
Intent s=new Intent(ctx,MyService.class);  
  
  
ctx.startService(s);  
  
  
}  
  
  
} 
 
 

2. Configure the license for the consumer to allow the system to receive startup messages. In AndroidManifest. xml:

Xml Code

 
 

  
  
< uses-permission android:name=
"android.permission.RECEIVE_BOOT_COMPLETED"/>   
  
  
< uses-permission android:name=
"android.permission.RECEIVE_BOOT_COMPLETED"/> 
 
 

3. Configure the consumer er to receive system startup messages. In AndroidManifest. xml

Xml code for Android auto-start

 
 

  
  
< receiver android:name=".app.BootReceiver">   
  
  
< intent-filter>   
  
  
< action android:name="android.intent.action.BOOT_COMPLETED"/>   
  
  
< category android:name="android.intent.category.HOME" />   
  
  
< /intent-filter>   
  
  
< /receiver>   
  
  
< receiver android:name=".app.BootReceiver"> 
  
  
< intent-filter> 
  
  
< action android:name="android.intent.action.BOOT_COMPLETED"/> 
  
  
< category android:name="android.intent.category.HOME" /> 
  
  
< /intent-filter> 
  
  
< /receiver> 
 
 

4. Start the simulator. A dialog box is displayed after the system is started.
