我正在开发一个使用Google地图更新位置的应用程序。到目前为止，我只有一个问题，那就是获得精确的位置许可。 这是我的清单文件。

这是我的IntentService，通过它我可以将控制传递给我的服务类。
public class MyLocationUpdate extends IntentService {
double latitude,longitude;
AppLogic app = new AppLogic();
HelpMe activity;
IETrackerDTO iedto= new IETrackerDTO();
public MyLocationUpdate() {
super("MyLocationUpdate");
}
@Override
protected void onHandleIntent(Intent intent) {
Log.d("Inside", "Intent Service");
/*IETrackerDTO ide = intent.getExtras().("currentUser");*/
ScheduledThreadPoolExecutor s = new ScheduledThreadPoolExecutor(1);
s.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
LocationFinder gps;
Log.d("Calling other service", "Calling other service");
gps = new LocationFinder(MyLocationUpdate.this);
latitude = gps.getLatitude();
longitude = gps.getLongitude();
Log.d("Location", latitude + " " + longitude);
updateLocation();
toast();
}
}, 0, 10, TimeUnit.SECONDS);
}
public void toast() {
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "Lat: " + latitude + " long:" + longitude, Toast.LENGTH_SHORT).show();
}
});
}
这是我的Service类，可以及时更新用户的lat长度

除了编译器要求位置权限而没有控件没有传递给服务类方法的事实外，一切运行得很好

包名必须是唯一的，因此按照惯例，您拥有的后向域名。这有助于将您识别为供应商，并授予对具有相同包名称（或供应商ID，如果您愿意）的任何服务，其他活动，应用程序，等等的访问权限。由于android是个人设备，因此没有用户授予权限。此外还列出了任何外国特权 uses-permission android：name =＆＃34; android.permission.ACCESS_FINE_LOCATION＆＃34; 将被授予供应商，假设他们被用户/运营商接受。
