我是Android的初学者...我正在创建一个应用程序来加载谷歌地图v2.But它没有加载并且每次都有一个消息不断崩溃不幸关闭。请帮我解决错误。谢谢你提前..我是一个普通的追随者堆栈溢出..
**my code**
**Main activity.java**
package com.mypack.test;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import android.os.Bundle;
import android.app.Activity;
import android.widget.Toast;
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();
}
}

感谢您花费宝贵的时间。我得到了解决方案......这是我的错误...... 正如Reghunandan和Patrik所说。引用谷歌Playstore服务是一个问题..我的应用程序引用了SDK目录中的google playstore服务，而不是我工作区中加载的google playstore版本。所以上面的错误被清除了..而且正在运行应用程序地图没有加载..我用以下代码检查了它
package myapp.mypack;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.widget.Toast;
public class MapActivity extends FragmentActivity {
String msgtype,sendernum;
// Google Map
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(check())
{
setContentView(R.layout.app_main);
Toast.makeText(this, "In Google play service.", Toast.LENGTH_LONG).show();
initFun();
}
else
{
Toast.makeText(this, "Google play service not available.", Toast.LENGTH_LONG).show();
}
}
private Boolean check()
{
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if(status==ConnectionResult.SUCCESS)
{
return true;
}
return false;
}
public void initFun()
{
SupportMapFragment sp = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
googleMap = sp.getMap();
googleMap.setMyLocationEnabled(true);
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
@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;
}
}

但我的地图正在加载......相反，它会提供一段时间的屏幕并显示 “谷歌播放服务不可用。”在代码中指定..但我检查了我的项目＆gt;属性＆gt; android。 google playstore库中有绿色刻度标记。 所以认为这是我的Playstore版本的问题.. * 我在我的galaxy s3 mini中运行应用程序。但它也显示相同的白色屏幕 ..我的手机中的Playstore构建版本是：4.3.11 。我唯一的解决方案就是更新Playstore并重新运行我的应用程序.logcat还显示我的手机的playore版本需要更新..请大家看看在我的查询..这是我的手机的Playstore版本的问题.. *
