    Guys, I solved my problem, First of all I deleted ' Trusted_Connection=true ' at the end of line 21.
    Secondly,
    I got this error on my screen "Encoding 1254 data could not be found. Make sure you have correct international codeset assembly installed and enabled.'" this can be 1252 or any number for you.

    The code mean:

    CodePage BodyName HeaderName WebName Encoding.EncodingName
    shift_jis 932 iso-2022-jp iso-2022-jp shift_jis Japanese (Shift-JIS)
    windows-1250 1250 iso-8859-2 windows-1250 windows-1250 Central European (Windows)
    windows-1251 1251 koi8-r windows-1251 windows-1251 Cyrillic (Windows)
    Windows-1252 1252 iso-8859-1 Windows-1252 Windows-1252 Western European (Windows)
    windows-1253 1253 iso-8859-7 windows-1253 windows-1253 Greek (Windows)
    windows-1254 1254 iso-8859-9 windows-1254 windows-1254 Turkish (Windows)
    csISO2022JP 50221 iso-2022-jp iso-2022-jp csISO2022JP Japanese (JIS-Allow 1 byte Kana)
    iso-2022-kr 50225 iso-2022-kr euc-kr iso-2022-kr Korean (ISO)

    In the the Android project, go to Properties -> Android Options

    Then Linker Options, in the "Additional supported encodings" check "your location".

    And the problem is fixed.
