Java Google maps v2 API集成问题

我试图将谷歌地图集成到我的android应用程序中，但在创建apk并在手机上启动（android 4.4.4）后，它崩溃了。若我在emulator上启动，我会收到消息“Failure[安装失败\缺少\共享\库]”。我能做什么

这是我的档案

MainActivity.java

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tieride);

    SupportMapFragment mapFragment =
            (SupportMapFragment)     getSupportFragmentManager().findFragmentById(R.id.map);

    if (savedInstanceState == null) {
        // First incarnation of this activity.
        mapFragment.setRetainInstance(true);
    } else {

        mMap = mapFragment.getMap();
    }
    setUpMapIfNeeded();
}

@Override
protected void onResume() {
    super.onResume();
    setUpMapIfNeeded();
}

private void setUpMapIfNeeded() {
    if (mMap == null) {
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
        if (mMap != null) {
            // Enabling MyLocation Layer of Google Map
            mMap.setMyLocationEnabled(true);
        }
    }
}

这是我的布局

<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"
            tools:context=".MainActivity" >


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

</RelativeLayout>

您的模拟器目标是否设置了谷歌API（谷歌公司）？上次我使用google map api时，我也有同样的体验，在我将目标设置为google api（google Inc.）-api级别（版本）后，它就工作了。

如果你读过同样的帖子，请检查一下：我这么做了。现在emulator像电话一样崩溃，因为您正在使用

SupportMapFragment

确保正确添加了支持库。
