我的 android 服务出现问题,无法启动:
这是我的代码片段 -
public class MainActivity extends Activity
{
static String exp_name = "";
@SuppressLint("SdCardPath")
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i("here", "1");
}
public void onStart(View view)
//triggered by start button viz present on R.layout.activity_main
{
startService(new Intent(MainActivity.this, ExperienceLoggerService.class));
Log.i("here", "2");
}
... code....
//inner class service (needs to be inner class for certain features of my APP)
public class ExperienceLoggerService extends Service
{
@Override
public void onCreate()
{
Log.i("here", "3");
super.onCreate();
}
.....code....
}
//back to outer class
....other code......
}
我的问题是我的android活动正常启动,
(即)“here 1”在活动启动时打印(LogCat),“here 2”在按下开始按钮时打印。
但是服务永远不会启动,“here 3”也不会打印!我只是不明白为什么?
这是我的android清单文件供参考:
