Parsing Error when install apk

[yuhong]

Case "downloadjob"
      If HttpUtils.IsSuccess(downloadurl) Then 
           src=HttpUtils.GetInputStream(downloadurl)
           'target=File.OpenOutput(File.DirDefaultExternal,"dj.apk",False)' if I use File.DirDefaultExternal then no install error.
           'target=File.OpenOutput(File.DirInternalCache,"dj.apk",False)'
           target=File.OpenOutput(File.DirInternal,"dj.apk",False)
           File.Copy2(src,target)
           target.Flush
           target.Close
           Dim i As Intent
           'i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(File.DirDefaultExternal,"dj.apk"))'NO ERROR
           'i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(File.DirInternalCache,"dj.apk"))
           i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(File.DirInternal,"dj.apk"))'ERROR
           i.SetType("application/vnd.android.package-archive") 
           StartActivity(i)
   End If

when I use File.DirDefaultExternal path,Application can download apk file, then install it,But I use DirInternalCache or dirInternal save file of download file,when install it show "Parsing Error" error!

The APK file must be in the storage card. Otherwise it is not accessible to the installer.

:BangHead:

For the device without the SD card can not be achieved automatically updated? !For example: Samsung 7500

The device may still have some external memory, even if it's not a separate SD Card. On one of my devices I have a NAND partition that would suffice.

Check what File.DirDefaultExternal actually points to.

Log(File.DirDefaultExternal)

Parsing error

Hi,

My application works fine on my testing device. But when I try to install this on a random device with the apk file I get a parsing error message. I found out that when the B4A Designer application is installed on that device, installing the the app with the apk-file works fine. How to install the app with the APK-file without the B4A Designer application???

 

[Erel]

I don't see how B4A Designer can affect the installation of any other application. How do you install the APK? Are you sure that it is not corrupted? Is it signed with your own key?

 

[frevacom]

Thanks for your reply.
I copied the APK on the SD card and selected it in the file explorer.
I don't think it's corrupted. The application works fine on my test device. How can I be sure?
The application is signed with my key.

 

[Erel]

How are you installing it? With the intent mentioned in the first post?

 

[frevacom]

I Compile & Run the project.
In the folder "Objects" I copy the apk file to a SD card. I put the SD card into the Android device and select the apk file.

What is the name of this APK?

It might be a problem in your specific device.
