我正在創建一個本機擴展，它顯示來自基於Flex的AIR應用程序的本地Google Map。您可以觀看lee brimelow的演示，以獲得這個想法：https://plus.google.com/110495278155587072613/posts/degSYVx8423谷歌地圖ane：RuntimeException：試圖創建多個DataRequestDispatchers
我得到了一個本機擴展的工作演示，只是用一些按鈕顯示一個活動，但當我試圖顯示地圖時卡住了。下面是對的setContentView（layoutID），我發現了異常：

我敢確信AIR和Android之間的通信是確定的，所以我只張貼我的本地代碼。 （當我取出地圖，本機擴展沒有問題的作品）
這裏是佈局的xml文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<fragment android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="300dp" />
</LinearLayout>
這裏是我的FREFunction
public class GoogleMapsFunction implements FREFunction {
@Override
public FREObject call(FREContext ctx, FREObject[] passedArgs) {
int layoutID, googleMapID;
Intent i = new Intent(ctx.getActivity(), WebViewActivity.class);
layoutID = ctx.getResourceId("layout.activity_google_maps");
googleMapID = ctx.getResourceId("id.map");
i.putExtra("layoutID", layoutID);
i.putExtra("googleMapID", googleMapID);
ctx.getActivity().startActivity(i);
return null;
}
}
這裏是我的活動
public class WebViewActivity extends Activity {
private GoogleMap map;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
int layoutID = getIntent().getIntExtra("layoutID", -1);
setContentView(layoutID);
int googleMapID = getIntent().getIntExtra("googleMapID", -1);
map = ((MapFragment) getFragmentManager().findFragmentById(googleMapID))
.getMap();
} catch(Exception e){
System.out.printf("WebViewActivity.onCreate failed with error:\n\"%s\"\n",
e.toString());
Toast.makeText(this, "WebViewActivity.onCreate failed: " +
e.toString(), Toast.LENGTH_SHORT).show();
}
}
}
這是我的AndroidManifest
<?xml version="1.0" encoding="utf-8"?>

android:label="@string/app_name">

</application>
</manifest>
我看到一些com.google.android.gms。條目堆棧跟蹤，所以我假設所有的谷歌庫加載正確。
我爲測試目的創建了一個單獨的純本機android應用程序。 在這個應用程序中，我設法創建了一個顯示地圖的活動，這個活動使用相同的佈局XML，相同的谷歌庫和相同的API密鑰。
任何想法的？
