机器人 - 如何打开Android的KML文件 [英] android - how to open kml file in android

问题描述

我保存在我的sdcard.I希望通过谷歌地图在我的应用程序中打开KML文件，所以我用下面的code，但我得到错误说机器人IllegalStateException异常无法执行的方法活动

I got a kml file stored in my sdcard.I want to open it through the google map in my app, so i used the below code but i am getting error saying "android illegalstateexception could not execute method of the activity"

我不想要绘制地图，一切都只是我想打开它已经存储在SD卡我的KML文件并显示它。

I dont want to draw map and all just i want to open a kml file which is already stored in my sdcard and show it.

当我谷歌，我得到了很多相关的基础上，借鉴DATAS地图项目，这个我不想。

我的code：

public void showmap(View v){

    File file = new File(Environment.getExternalStorageDirectory(), "10.kml");
    Intent map_intent = new Intent(Intent.ACTION_VIEW);
    map_intent.setClassName("com.google.earth", "com.google.earth.EarthActivity");
    map_intent.setDataAndType(Uri.fromFile(file), "application/vnd.google-earth.kml+xml");
    startActivity(map_intent);
}
