使用以下代码时，我的Google地图会在意图开始时崩溃。请帮我修复代码。提前谢谢。
MainActivity.java
package com.example.googlemaps;
import info.androidhive.googlemapsv2.R;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
public class MainActivity extends Activity {
// Google Map
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* function to load map. If map is not created it will create it for you
* */
private void initilizeMap() {
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();
}
}
}
@Override
protected void onResume() {
super.onResume();
initilizeMap();
}
}
activity_main.xml中

就是这样。我使用eclipse Juno和api是4.4.2 API 19
答案 0 :(得分：1)
在AndroidManifest.xml文件中添加以下MAP_KEY。
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
