Android開發之開機啟動沒有介面的應用程式

在Android系統中,有介面的app一定是有Activity的,沒有介面的app,那就是一個Service了。

Service如何啟動呢?辦法和Activity的啟動一樣,也是Intent對象。我講的是如何寫一個開機後台啟動的app。

首先是AndroidMainfest註冊開機啟動許可權:

還要註冊廣播訊息接受者:


接下來是廣播接收者:

public class BootReceiverextends BroadcastReceiver {


private StringLOG = "BootReceiver";

@Override

public void onReceive(Context arg0, Intent arg1) {

// TODO Auto-generated method stub

Log.i(LOG, "onReceive");

Intent mBootIntent = new Intent(arg0, MyService.class);

arg0.startService(mBootIntent);

}

}

MyService.Java:

public class APTServiceextends Service {

private String LOG = "APTService";

public void onCreate() {

super.onCreate();

Log.i(LOG, "Oncreate");

Toast.makeText(getApplicationContext(), LOG + "onCreate start!",

Toast.LENGTH_LONG).show();

run(context);

Toast.makeText(getApplicationContext(), LOG + "onCreate end!",

Toast.LENGTH_LONG).show();

}


@Override

public IBinder onBind(Intent intent) {

// TODO Auto-generated method stub

Log.i(LOG, "onBind");

Toast.makeText(getApplicationContext(), LOG, Toast.LENGTH_LONG).show();

returnnull;

}

}


這樣做,你開機的時候就能收到Toast訊息了!
