In computer using a browser to download and install directly on the phone is good , but with the mobile phone to access action downloaded file is inconsistent with the original file size , and installation errors TIP: An error occurred while parsing package .
action code is as follows :
public ActionForward execute (ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
URL downUrl = new URL ("/ APPDown / android / HGT.apk");
URLConnection conn = downUrl.openConnection ();
InputStream is = conn.getInputStream ();
BufferedInputStream in = new BufferedInputStream (is);
response.addHeader ("Content-Disposition", "attachment; filename =" + "HGT. apk ");
/ / response.setContentType ("application / vnd.android.package-archive");
response.addHeader ("Content-Type", "application / vnd.android.package-archive");
OutputStream outputStream = response.getOutputStream ();
byte [] data = new byte [1024];
int size = 0;
int l = 0;
while ((l = in.read (data))> 0) {
size + = l;
outputStream.write (data, 0, l);
}
response.addHeader ("Content-Length", size + "");
outputStream.flush ();
outputStream.close ();
in.close ();
is.close ();
return null;
}
files can be downloaded to the phone normally . But the installation fails.
------ Solution ------------------------------------ --------
this APK APK than what non-
What is the phone project
------ Solution -------------------------------- ------------
computer access is normal, mobile access is a problem, another good point phone? May be related to content , capacity and other limitations on ( unfortunately mobile access to some of the details can not see )
------ Solution -------------------- ------------------------
this mobile browser is not what difference does ( check under this item is better ) , I think the most may still limit the differences of resources .
How much of your apk file ? If the change is small enough will not have a problem
------ Solution ----------------------------- ---------------
I also tend to believe that the development up to now is not no difference , the difference should not big , but it is the performance and pc web a difference, indicating there are still differences .
phone down after a different browser to download a file is not the same size ? How much specific size
------ Solution ------------------------------------ --------
is accurate to the byte is also the same? ( Which is exactly the same , the problem would be much easier )
installation error occurs What do
------ Solution ------------------------------ --------------
critical attention to this section :
response.addHeader("Content-Disposition", "attachment;filename=" + "HGT.apk");
//response.setContentType("application/vnd.android.package-archive");
response.addHeader("Content-Type", "application/vnd.android.package-archive");
probably the phone that supports this type of environment ministry , leading download exception.
------ Solution -------------------------------- ------------
hard top, in which finally have a bosom friend ! I start phone Huawei G510T8951 months , is this situation , no matter how the phone can not install the APK file , the computer can be in the phone under normal installation , solution ?

while ((len = in.read (buffer))! = -1)
{
out.write (buffer, 0, buffer.length);
total + = len;
pg.setProgress (total);
Thread.sleep (20); ------------- download when you can let sleep for a while !
}
out.flush ();
in.close (); ----- Note stream shutdown sequence
out.close ();
return file;

not a mobile phone project, which is written in java me backstage , when the phone asked me when this action will download an installation file to the user's mobile phone.

likewise for the other phone , click on the downloaded file to install it on an error message: There was a problem parsing package .
but the original file is good, it may be corrupted files . But details unclear. Expect someone pointing.

simply, it is a problem with mobile downloads
phone to download the details of what ? Is installed in the phone 's browser url to access or direct access to mobile apps , the program , then what kind of procedures.

is installed in the phone 's browser url to access

should be no difference , and I use the phone on multiple browsers for testing , and finally downloaded files are out of this problem , not paper 1.06M. the Internet looking for a long time no information in this regard , but had to post to ask.

I do not want the top of this post, but my question is not resolved , look prawn Ariadne .

there are many complex issues bias is likely to be no ready-made answers , we need to find answers to actively communicate with it

have time to first understand the mobile browser characteristics and differences , hoping to find some clues

modified under way yesterday , and now mobile phone to download the file size with the same size as the original file (1.06mb), but it still occurs during installation error: parse package problems.
------ For reference only -------------------------------------- -
is the same, when you install the phone prompts an error message: There was a problem parsing package
------ For reference only ---------------- -----------------------
no stack information do ? Just one problem parsing package for the analysis that much
You said manual installation is good , but now installed automatically when the installation files and manually when it is consistent, then it is automatically installed programs write their own ?
------ For reference only -------------------------------------- -
No, the installer did not write , this feature I found in the U.S. group net , that is, when the user simply take a mobile phone to scan a two-dimensional code and it will return a corresponding mobile installation file, click on the download is complete after the phone will automatically prompt the user to install .
------ For reference only -------------------------------------- -
I do not understand since it is exactly the same installation file , but also through the phone comes with the installation program to install, how will install fail?
------ For reference only -------------------------------------- -
This is where the problem lies , puzzling in ......
------ For reference only ----------------------- ----------------
which aspect is certainly not the same as , or from known conditions that some of them are wrong , but also a good check .
------ For reference only -------------------------------------- -
the same results .
------ For reference only -------------------------------------- -
downloading is possible only under the down time of installation files at the click of a mistake . Error message just exactly the same as described above .

mobile Brush up on March 1 of the package , the situation remains the same , the phone can not be installed under the APK , in addition to problems when parsing package , as well as the software is not installed and so prompt situations < br> ------ For reference only ---------------------------------------
because there are other things in the busy so this abeyance , but the problem still exists there a way upstairs is feasible , and therefore can not bear stickers.

I also encountered the same problem , can be downloaded using a computer installed properly , but the phone downloaded apk file is only 1K, parsing errors when installing .
