Android开机自动启动程序

1.定义一个BroadcastReceiver

 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.配置Receiver的许可,允许接收系统启动消息，在AndroidManifest.xml中：

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

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

 3.配置Receiver,可以接收系统启动消息，在AndroidManifest.xml中

 <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>
