android - 如何在android中打開kml文件

Question

我得到了一個kml文件存儲在我的sdcard.I想通過我的應用程序中的谷歌地圖打開它，所以我用下面的代碼，但我得到錯誤說「android illegalstateexception無法執行活動的方法「

我不想繪製地圖，所有隻是我想打開一個已存儲在我的SD卡並顯示它的kml文件。

當我谷歌我有很多項目相關的基於數據繪製地圖，這我不想要。

我的代碼：

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); 
} 

我的Android清單文件

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.lyold" 
    android:versionCode="1"

      </intent-filter> 
     </activity> 
     <activity 
      android:screenOrientation="landscape" 
      android:name=".Home" /> 

     <activity android:name="com.google.earth.EarthActivity" android:screenOrientation="landscape"/> 




    </application> 

</manifest>

檢查AndroidManifest.xml FILE相關權限，並確保您嘗試打開的文件路徑（10.kml）。除此之外，您的代碼中一切都很好。
