1.     定义一个BroadcastReceiver

代码:

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

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