简单android Service 创建与启动示例

源码示例如下：

ServiceExample.java

public class ServiceExample extends Service {

final private String LOG_TAG = "ServiceExample";

private BroadcastReceiverHelper rhelper;

@Override

public IBinder onBind(Intent intent) {

return null;

}

@Override

public void onCreate() {

super.onCreate();

rhelper=new BroadcastReceiverHelper(this);

rhelper.registerAction("android.intent.action.menulongpress");

}

@Override

public void onDestroy() {

super.onDestroy();

rhelper.unregisterAction("android.intent.action.menulongpress");

}

...

}

要启动某个service, 如下示例：

...

Intent serviceIntent = new Intent();

serviceIntent.setAction("com.example.android.home.menu_longPressService");

startService(serviceIntent);

serviceIntent.setAction("com.android.phone");

startService(serviceIntent);

如要在Service中启动某个Activity, 示例如下（注意设置FLAG_ACTIVITY_NEW_TASK）：

xxxActivity tb = newxxxActivity();

intent = new Intent();

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.setClass(context, tb.getClass());

startActivity(intent);
