我是stackoverflow的新手 我有使用的谷歌地图测试项目 here 我喜欢教程，但应用程序崩溃。
我完成了教程中的每一步，获得了android键，添加了库等等： 我的类似问题是这个链接： here 但它没有任何有效的答案。 我完全删除eclips，卸载java JDK和JRE，甚至我的整个系统java。但应用程序崩溃了。 任何身体可以帮助我吗？非常感谢你
这里是我的代码：
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.SupportMapFragment;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.NavUtils;
public class MainActivity extends FragmentActivity {
private GoogleMap googleMap;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
private void initilizeMap() {
if (googleMap == null) {
//googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
googleMap = ((SupportMapFragment) getSupportFragmentManager().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();
}
}
}
}
和清单文件是：

android:value="AIzaSyBYju6h2BWvZOaSDQpe5f9tv6fJsZy6cY8" />
</manifest>
和布局是：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

android:layout_width="match_parent"

</RelativeLayout>
这是logcat：

答案 0 :(得分：0)
更改
public class MainActivity extends FragmentActivity {
到
public class MainActivity extends Activity {
更改此
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
到
googleMap = ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
您还需要清单
中的应用程序标记中的以下内容<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
这是google play services rev 13的要求
编辑：
移动
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyBYju6h2BWvZOaSDQpe5f9tv6fJsZy6cY8" />
清单
中的应用程序内部标记答案 1 :(得分：0)
试试这个。
您的MainActivity
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
// Valida si el mapa no se creo correctamente
if (googleMap == null) {
Toast.makeText(getApplicationContext(), "Sorry! el mapa no pudo ser cargado", Toast.LENGTH_SHORT)
.show();
}
}
}
在你的布局中
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
在清单中，我在MAC中使用了这些行，因为在Windows中正常工作没有它们
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
答案 2 :(得分：0)
我有类似的问题。我添加：
import com.google.android.gms.maps.SupportMapFragment;
将xml更改为
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/header" />
解决了这个问题。我希望你也解决它！
