android - 将 Google Maps API 实现到 Google Glass 时出错

Question

注意:我们是在 Glass 上运行它，而不是模拟它

所以，当我包括:

<uses-library android:name="com.google.android.maps"/>

在 list 文件中。我收到错误:

Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY

因此，如果我删除 list 中的行，应用程序将在到达 map Activity 时崩溃，该 Activity 显示为:

package com.example.mapping;
import android.app.Activity;
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.os.Bundle;
import android.app.ActionBar;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;

public class MapActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

    // Get a handle to the Map Fragment
    GoogleMap map = ((MapFragment) getFragmentManager()
            .findFragmentById(R.id.mapView)).getMap();

    LatLng war = new LatLng(-33.867, 151.206);

    map.setMyLocationEnabled(true);
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(war, 13));

    map.addMarker(new MarkerOptions()
            .title("Mission Drop Zone")
            .snippet("Navigate to Enemy Hideout")
            .position(war));



}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.map, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.mapView) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_map, container,
                false);
        return rootView;
    }
}}

据我了解，Google map 需要 Google Play 服务。目前，谷歌眼镜仍未正式提供 Google Play 服务。另外要注意的是，Glass 没有设备上的 GPS，它实际上使用手机中的 GPS 进行高精度定位。
