googleMap.setMyLocationEnabled仅在从手机启动时有效

Question

我添加了行googleMap.setMyLocationEnabled(true);在我的代码中。

当我从手机上启动应用程序时，地图和用户的位置就会显示出来，一切都很好。

然而，当我从电脑上启动它时，我得到了一个错误：

08-28 11:19:01.524: W/dalvikvm(30617): VFY: unable to resolve static field 20875 (t) in Lyo; 08-28 11:19:01.524: D/dalvikvm(30617): VFY: replacing opcode 0x62 at 0x000e 08-28 11:19:01.529: W/dalvikvm(30617): VFY: unable to resolve static field 20875 (t) in Lyo; 08-28 11:19:01.529: D/dalvikvm(30617): VFY: replacing opcode 0x62 at 0x000d 08-28 11:19:02.129: I/dalvikvm(30617): Failed resolving Lcom/google/android/gms/location/internal/ParcelableGeofence; interface 4023 'Lglm;' 08-28 11:19:02.129: W/dalvikvm(30617): Link of class 'Lcom/google/android/gms/location/internal/ParcelableGeofence;' failed 08-28 11:19:02.129: E/dalvikvm(30617): Could not find class 'com.google.android.gms.location.internal.ParcelableGeofence', referenced from method gls.a 08-28 11:19:02.134: W/dalvikvm(30617): VFY: unable to resolve check-cast 2086 (Lcom/google/android/gms/location/internal/ParcelableGeofence;) in Lgls;

它似乎找不到Class ParcelableGeofence。为什么？

在这两种情况下，都会向谷歌API发出请求。所以API密钥是可以的

如果我从代码中删除googleMap.setMyLocationEnabled(true);，一切都会很好。

Answer 1

试试这个：

    googleMap = ((MapFragment) getFragmentManager()
            .findFragmentById(R.id.map)).getMap();
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    googleMap.setMyLocationEnabled(true);

如果这不起作用，请发布您的代码、清单、布局xml

Answer 2

这只是一个黑暗中的镜头，但如果仅在加载地图时启用位置层，会发生什么？像这样：

googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
    @Override
    public void onMapLoaded() {
        googleMap.setMyLocationEnabled(true);
    }
});

地图加载是否正确，然后崩溃？

问题是计算机没有GPS或任何其他方式来跟踪位置
