Android Question [SOLVED] UDG AppUpdate issue ...

[Yayou49]

Hi,

I'm using appupdate from UDG.

I'm facing a known problem if I read some threads about "exposed beyond app through Intent.getData()"

Does someone already apply change on appupdate source code to avoid this error ?
I must admit that I'm not really comfortable with explainations given by Erel ....

Problem occur on lines:

Dim i As Intent
i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(File.DirDefaultExternal, "tmp.apk"))
i.SetType("application/vnd.android.package-archive")
StartActivity(i)

So, if someone can help me, it will be very useful for me !
Thanks in advance.

What error? You forget to POST THE COMPLETE ERROR.
Asuming you are targetting Api 26 you need to use FileProvider as it is no longer allowed to use file:// paths...

See this tutorial: https://www.b4x.com/android/forum/threads/version-safe-apk-installation.87667/#content

Thanks for the link, but I already read it and as I said, I'm really not comfortable with this code ......
That's why I was asking if someone already implement this code in appupdating ....

I'm happy to give you (with UDG authorisation) my updated class cl_appupdate (attached).
It has been done with a part of Erel's code about Fileprovider.
I've tested it with my phone (Android 7.0 SdkVersion 24) and it works fine !

So:

1: add to your manifest

AddManifestText(<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="18" />
)

AddApplicationText(
  <provider
  android:name="android.support.v4.content.FileProvider"
  android:authorities="$PACKAGE$.provider"
  android:exported="false"
  android:grantUriPermissions="true">
  <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/provider_paths"/>
  </provider>
)
CreateResource(xml, provider_paths,
   <external-files-path name="name" path="" />
)
AddPermission(android.permission.REQUEST_INSTALL_PACKAGES)

2: Add in your starter class:

Sub Process_Globals
    Public rp As RuntimePermissions
    Public SharedFolder As String 
End Sub

Sub Service_Create
    SharedFolder = rp.GetSafeDirDefaultExternal("")
End Sub

3: update the cl_appudate

If someone can test it with version greater than mines, feel free to give us a feedback.
