安卓错误 : Binary XML file line #16: Error inflating class fragment when adding map fragment

Question

我正在尝试使用 map api v2 显示 map 。

这是我的 xml 代码:

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

这是 Activity 中的代码:

 import com.google.android.gms.maps.GoogleMap;
 import com.google.android.gms.maps.MapFragment;


 public class MainActivity extends Activity  {

 private GoogleMap map;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

我正在尝试在我的设备上运行它(Andorid 4.1.2，即 api 16)我在我的项目中添加了 google-play-services-lib。当我运行应用程序时，它就崩溃了。

这是完整的 logcat 日志:

Answer 1

你的meta标签应该在application标签下

 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
   ...// rest of the code
   <meta-data
     android:name="com.google.android.maps.v2.API_KEY"
     android:value="**MY KEY**"/>
 </application>

查看主题将 API key 添加到您的应用程序下的文档

https://developers.google.com/maps/documentation/android/start

编辑:

你也不见了

  <permission
    android:name="stringbind.nikolacjenolomacdemo.permission.MAPS_RECEIVE"
    android:protectionLevel="signature"/>

也使用你的包名

   <uses-permission android:name="stringbind.nikolacjenolomacdemo.permission.MAPS_RECEIVE" />

也不见了

    <uses-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>
