圖片有點霧抱歉 感謝大大浪費時間 幫我看這麼多的程式碼

 java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=100, result=-1, data=Intent { dat=content://com.android.providers.downloads.documents/document/msf:12 flg=0x1 }} to activity {com.example.wells.testfire/com.example.wells.testfire.MainActivity}: java.lang.NumberFormatException: For input string: "msf:12"
at com.example.wells.testfire.MainActivity.getPath(MainActivity.java:253)
at com.example.wells.testfire.MainActivity.onActivityResult(MainActivity.java:211)   
  他的253行以及211程式碼:
253:    Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
211:  imgPath = getPath(MainActivity.this, uri);

我有參考其他網友的檔案 可是我還是會跳錯誤 請幫幫我感恩

java.lang.NumberFormatException: For input string: "msf:12"
我猜是這個 : Long.valueOf(id)

檢查一下你的id可能有問題
