Question

我实施了谷歌地图android api v2。虽然我可以看到地图区域，我已经尝试了所有其他来源..！这就是我可以查看的所有输出...请帮助..！

我的MapActivity.java

package nav.android.app.navigationsystem;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;

import android.os.Bundle;
import android.app.Activity;

import android.util.Log;
import android.widget.Toast;

import android.view.Menu;

public class MapActivity extends Activity {

// Google Map
public GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

   try {
        Log.e("loading map. . . .","loading map. . . ");
        // Loading map
        initilizeMap();

    } catch (Exception e) {
        Log.e("catch. . .", "catch. . .");
        e.printStackTrace();
    }
  /* MapFunctionality mf = new MapFunctionality();
   mf.currentLoc();
   mf.addMarker();*/
}
/**
 * function to load map. If map is not created it will create it for you
 * */
private void initilizeMap() {
 // MapFunctionality mf = new MapFunctionality();
    Log.e("initializing map. . . ","initializing map. . ");
    if (googleMap == null) {
         googleMap= ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT).show();
        }
     // mf.currentLoc();
    //  mf.addMarker();
    }
}

@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
protected void onResume() {
    super.onResume();
    initilizeMap();
}

}

我的activity_map.xml文件是

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

       android:layout_height="match_parent"
       android:layout_alignParentTop="true" />

</RelativeLayout>

Answer 1

这是小清单

API密钥
包名称
最新的Google Play服务设备（Availability）
您的密钥库（用于签署应用）

顺便说一句。您可以删除MapsReceive权限
