我已經實施谷歌地圖android api v2。雖然我可以看到地圖區域，但我嘗試了所有其他來源..！這就是我可以查看的所有輸出...請幫助..！我無法查看地圖，只顯示谷歌地圖區域
我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();
}
}

你檢查谷歌地圖API的Android v2是ON ??? – Namy
首先檢查您的LOGCAT是否存在來自Google地圖API的警告或錯誤！ –
它說谷歌播放存儲缺失... BT我已經安裝谷歌播放服務的API 19 – Manisha
