Download and Install APK

To install an app you need a code like this:

However, you cannot install from File.DirInternalCache or File.DirInternal, you must copy the file to File.DirDefaultExternal for example, the reason is because only your app has access to the DirInternal directories, the installer don't.

B4X:

Dim i As Intent 

i.Initialize(i.ACTION_VIEW, "file:///sdcard/MyAPK.apk")
i.SetType("application/vnd.android.package-archive")

StartActivity(i)

Thanks NJ, the problem is how do i copy the file from the cache? I tried this,


but i cant seem to ever find the file to copy it?? Is it a permission issue? Is there a way for me to view the internal cache via some sort of file explorer?

I don't use httputils or httputils2, but, you should copy the file when the download is successful.

Hi,

I could able to download file(httputils2) from given location, but where in mobile it shall store, unable to see the downloaded file..Can share the path.

You must save the downloaded file in Sub JobDone to a place where you want it to be...
See the examples in my signature (create dynamic jpg) and be inspired by that code. Look JobDone-sub and try to understand how i write the image (or in your case the apk) to disc.

You may use my AppUpdating library as is or be inspired by its source code.
Sorry to post without any link and in a so concise way, but currently I am on the road with a very small device.

Hi,

Thanks for your inputs and example shared. i could able to download, but file name as is not coming as-is. coming as java.lang.object@..I am new to this concept..I am downloding a zip file from a url downloading with the mentioned name..not the same name with extension coming.

I am using the same code you shared in the example.

Case "Job4"
'print the result to the logs

Dim OutStream As OutputStream
Log("DownloadReady: "&Job.Tag)
OutStream = File.OpenOutput(File.DirRootExternal, Job.Tag, False) ' Job.Tag is read to set the Original Filename we specify earlier in the creation of the Job
File.Copy2(Job.GetInputStream,OutStream) ' save the file
OutStream.Close
Log(Job.Tag&" written to "&File.DirRootExternal) ' Write the Originalname to the log to see what happens ;-)

Dim i As Intent
i.Initialize("android.intent.action.MEDIA_SCANNER_SCAN_FILE", _
"file://" & File.Combine(File.DirRootExternal, Job.Tag))
Dim p As Phone
p.SendBroadcastIntent(i)

ToastMessageShow("Download Complete", True)
ToastMessageShow("Sucess", True)

Thanks.. problem resolved..
