Question

我仍在努力完成我的第一次Android挑战（对我自己;））我现在处于一个我想测试/调试某些基于位置的功能的位置，但我根本无法让它工作......

这是我订阅导航更新的代码：

LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// We create the mock location provider
try {
    locationManager.addTestProvider("mockgps", false, false,
            false, false, true, true, true, 0, 5);
} catch (IllegalArgumentException e) {
    Log.w(getString(R.string.debug_tag),String.format("%s: mockgps was already created...", this.getClass().getSimpleName()));;
}

// Debugging we have the providers we need
List<String> providers = locationManager.getAllProviders();
Log.v(getString(R.string.debug_tag),String.format("%s: location provider ={%s}...", this.getClass().getSimpleName(), providers));

locationManager.requestLocationUpdates("mockgps", 100L, 0, locationListener);

// Some code removed
locationManager.setTestProviderEnabled("mockgps", true);

这是我推送到 / data / misc / location / mockgps / nmea

的NMEA文件

我确实在监听器中有相当全面的日志记录，绝对没有发生...... 我没有获得GPS状态更新，也没有任何位置更新...

您将非常感谢您的帮助。这是一个真正的痛苦，因为我甚至无法想到必须在真实手机上进行任何单一测试的麻烦（除了砖块的风险，我只有自己的“真正的”手机）。

我仍然使用模拟器，我的测试设备是2.3.3。

对于记录，这里是监听器代码：

LocationListener locationListener = new LocationListener() {

    public void onLocationChanged(Location location) {
        // Called when a new location is found by the network location provider.
        Log.v(getString(R.string.debug_tag),String.format("%s: got new location (%s)",
                NavManager.class.getSimpleName(), location.toString()));
        if (currentLocation != null) {
            lastLocation = currentLocation;
            currentLocation = new Location(location);
        }

        if (navigation == null) {
            navigation = new Navigation();
        }

        navigation.setLocation(currentLocation);
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
        locProvider = provider;
        locProviderStatus = status;
        Log.v(getString(R.string.debug_tag),String.format("%s: location provider status changed (povider=\"%s\", status=%d)",
                NavManager.class.getSimpleName(), locProvider, locProviderStatus));
    }

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
  };

Answer 1

您只需从DDMS透视图发送坐标即可测试代码，无需加载NMEA文件。对于坐标，高度，速度，跨度，strings等数据非常多。从该文件中提取的速度，航向，卫星数量，跟踪卫星。做简单的方法。提取所有这些字符串将花费你很多时间。

使用DDMS中的位置控制，您仍然可以发送一些模拟坐标，实际上您可以模拟同时发送相同NMEA文件的GPS设备，但使用比解析/提取所有字符串更简单。

请在此处查看提供NMEA文件http://aprs.gids.nl/nmea/

的信息

Answer 2

模拟器中存在一个错误，因此NmeaListener onNmeaReceived（long timestamp，String nmea）从未收到任何内容。

无法使基于NMEA文件的模拟位置提供程序工作
