Download and install

I want to create a button on my app where the user click and the app download the apk and tell the android to install it. How can I do it ?
I know how to download but how can I tell the android to install it with my own app being running ?

After downloading the file you could install it like this:

B4X:

Dim iIntent As Intent 

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

StartActivity(iIntent)

Nice! But the download method on FTP dont require a URI, how can I convert an absolute FTP local path to a URI ? Im download things on the path File.DirInternal how can I access File.DirInternal using a URI format ?
See the download code:

B4X:

mFTP.DownloadFile("App.apk", _
         True, _
         File.DirInternal, _
         "App.apk")

Thanks

You just need the location of the downloaded file:

B4X:

TheFile = File.DirInternal & "/MyApk.apk"

iIntent.Initialize(iIntent.ACTION_VIEW, "file:///" & TheFile)

...

You download first, finished downloading, then install.

Ok, I downloaded the file and verified that the file was there. But Im getting this BIG error see:

Oops!, I made a boo-boo, I have corrected the example, it should work now.

Vinians2006 · Mar 23, 2012

Thanks a lot. Its seems that worked 50%, now Im getting this message "Há um problema com a anaslise do pacote" in english "There's a problem analising the package". Its because its a not signed apk ?

NJDude · Mar 23, 2012

What do you mean by signed?, hey, if you want, go to the chat room it will be faster.

Erel · Mar 24, 2012

It is not related to the signing key.

The file must be located in the storage card. The installer cannot access files stored in the internal folder.
