An update question!

Question

Hi,

Here's the problem I'm facing: trying to do my own application update I download the update apk from a web server on the sd card and then I launch the Package Installer with the downloading path (while the old application is running). So far after the package installer starts and the user agrees to install the application I get the following message "MyApp Could not be installed on this phone" and in the logcat then following message is printed: "No package identifier when getting value for resource number 0x00000000". I could not find a reason for this behaviour, so please if there is something that I'm missing do point it to me!

try
 {
   BufferedInputStream getit = new BufferedInputStream(new URL("http://mywebserver:8080/myapk.apk").openStream());
   FileOutputStream saveit = new FileOutputStream(path);
   BufferedOutputStream bout = new BufferedOutputStream(saveit,1024);
   byte data[] = new byte[1024];
   int readed = getit.read(data,0,1024);
   while(readed != -1)
    {
        bout.write(data,0,readed);
        readed = getit.read(data,0,1024);
    }
    bout.close();
    getit.close();
    saveit.close();
}
catch(Exception e)
{
   e.printStackTrace
}

Try to use the following sample intead of the "package installer" version. The sample will not explain how to download the file from the server. It will assume it's already in a byte array.

byte[] data = dataReadFromServer;

FileOutputStream outStream = openFileOutput("somename.apk", Context.MODE_WORLD_READABLE);
outStream.write(data);
Intent intent = new Intent();
String absolutePath = "file://" + getFilesDir().getAbsolutePath() + "/" +
"somename.apk"; 
intent.setAction(android.content.Intent.ACTION_VIEW); 
intent.setDataAndType(Uri.parse(absolutePath), "application/vnd.android.package-archive"); 
startActivity(intent);
