在我的.aspx
页面中,我有下载按钮,其中onclick
下载.apk
文件。Error使用Android手机浏览器从Asp.net网站下载.apk
当我在我的电脑上运行它工作正常.apk
文件得到我的电脑下载。
但是,当我用我的android手机去那个网站,并点击下载按钮,它将开始下载,但文件点击给出了错误解析软件包时出现问题。
而且实际文件大小604KB(而来自的Andorid手机下载给22KB)
下载的文件(22KB)包含HTML内容。
private void DownloadFile()

string getPath = "demo_Android/demoAndroid.apk";
System.IO.Stream iStream = null;

// Length of the file:

// Total bytes to read:

// Write the data to the current output stream.
Response.OutputStream.Write(buffer, 0, length);
// Flush the data to the HTML output.
Response.Flush();

dataToRead = dataToRead - length;

else

}

finally

,你可以下载你的文件,当你直接去下载链接,HTTP://yourwebsite/demo_Android/demoAndroid.apk – TimVK
这不是错误,但我认为在它的每一个冲水1K太快了!也没有理由在每个循环上重新创建缓冲区。有没有任何情况下,Android有保护,不允许下载.apk文件? – Aristos
这行也可能会产生你的错误'Response.Write(“Error:”+ ex.Message);' - 你需要记录你的错误。如果你发送数据中间,这个错误文本,然后你的包被打破。 – Aristos
