Question

注意：我们在Glass上运行它，而不是模仿它

因此，当我加入时会出现问题：

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

清单文件中的

。我收到错误：

Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY

因此，如果我删除清单中的行，应用程序将在访问以下内容的地图活动时崩溃：

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;
    }
}}

根据我的理解，Google地图需要Google Play服务。目前，Google Play服务尚未在Glass正式上市。另外另一个注意事项是，Glass没有设备上的GPS，它实际上使用手机上的GPS进行高精度定位。
