Question

我有一个kml文件存储在我的SD卡中。我想通过我的应用程序中的谷歌地图打开它，所以我使用下面的代码，但我收到错误说“android illegalstateexception无法执行活动的方法”< / p>

我不想绘制地图，只是我想打开一个已经存储在我的SD卡中并显示它的kml文件。

当我谷歌它我有很多与绘制地图相关的项目基于数据，这我不想要。

我的代码：

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);
}

检查AndroidManifest.xml FILE相关权限，并确保您尝试打开的文件路径（10.kml）。除此之外，你的代码中的一切都很好。
