手动添加位置更新停止在Eclipse工作 [英] Manually added location updates stop working in Eclipse
问题描述
我工作的一个1.5的Android应用程序。在Windows XP上开发在Eclipse 3.4.2。我有一个图形页面，都要求更新等。
I'm working on a 1.5 Android application. Developing in Eclipse 3.4.2 on Windows XP. I have a MapView, have requested updates, etc.
的问题是，经过第一手动注入的GPS坐标，该应用停止认识到了GPS坐标已发送。
The problem is that after the first manually injected GPS coordinate, the app stops recognizing that a GPS coord has been sent.
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
MapController mc = mapView.getController();
TextView locationText = (TextView) findViewById(R.id.LocationBar);
LocationListener locationListener = new MyLocationListener(mc, itemizedOverlay, locationText);
lm.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0,
locationListener);
然后MyLocationListener只需在一个TextView以匹配新的GPS坐标的变化值。
Then MyLocationListener simply changes the value in a TextView to match the new GPS coordinate.
public void onLocationChanged(Location loc) {
if (loc == null) {
return;
}
double lat = loc.getLatitude();
double lng = loc.getLongitude();
GeoPoint p = new GeoPoint(
(int) (lat * 1E6),
(int) (lng * 1E6));
mc.animateTo(p);
itemizedOverlay.addOverlay(new OverlayItem(p, "title", "snippet"));
String location = String.format("%f lat %f long", lat, lng);
locationText.setText(location);
}
我添加了一些记录在onLocationChanged方法，它永远只能看到一个位置的第一的时候，我尝试发送更新。所有后续的不火的onLocationChanged方法。
I added some logging in the onLocationChanged method and it only ever sees a Location the first time that I attempt to send an update. All subsequent ones don't fire the onLocationChanged method.
附加信息：
在logcat的输出如下：
The logcat output is as follows:
10-02 17:22:34.423: INFO/gps(6671): Provider gps is has status changed to 1. Extras: Bundle[mParcelledData.dataSize=52]
首先GPS更新是伪造的：
First GPS update is faked:
10-02 17:22:49.383: INFO/gps(6671): Location provided by location provider: Location[mProvider=gps,mTime=-1000,mLatitude=25.0,mLongitude=23.0,mHasAltitude=true,mAltitude=0.0,mHasSpeed=false,mSpeed=0.0,mHasBearing=false,mBearing=0.0,mHasAccuracy=false,mAccuracy=0.0,mExtras=Bundle[mParcelledData.dataSize=52]]
10-02 17:22:49.444: INFO/gps(6671): Provider gps is has status changed to 2. Extras: Bundle[mParcelledData.dataSize=52]
据的http://developer.android.com/reference/android/location/LocationProvider.html#AVAILABLE ，即2映射到可用。
According to http://developer.android.com/reference/android/location/LocationProvider.html#AVAILABLE , that 2 maps to "Available".
只要是可用被设定，没有其他地方获得通过。似乎有点违反直觉。
As soon as that "Available" gets set, no other locations get passed through. Seems a bit counterintuitive.
推荐答案
我相信你正在经历模拟器的GPS驱动程序的bug。
I believe you are experiencing a bug in the GPS driver of the emulator.
一个解决方法的1.5版本的SDK包含在的错误报告。从那里引述如下：
A workaround for the 1.5 versions of the SDK is included in the bug report. To quote from there:
在模拟器，在主屏幕上，preSS菜单 - >设置 - > 日期和放大器;时间 - >取消选中自动 - >选择时区， 并选择合适的时区（即你的）。
In the emulator, on the Home Screen, press "Menu" -> "Settings" -> "Date & Time" -> Uncheck "Automatic" -> "Select Time Zone", and choose the right time zone (ie, yours).
A <一个href="http://android.git.kernel.org/?p=platform/hardware/libhardware%5Flegacy.git;a=commit;h=613d25b8c0fd1ab92c566d965e3cd7da85c31ee0"相对=nofollow>修复包含在1.6版本的SDK。
A fix is included in the 1.6 release of the SDK.
