My program looks like:
(Android 7.1.2, SdkVersion=25)

B4X:

If phone.SdkVersion >= 24 Then     
     i.Initialize("android.intent.action.INSTALL_PACKAGE", GetFileUri(apkname))
     i.Flags = Bit.Or(i.Flags, 1) 'FLAG_GRANT_READ_URI_PERMISSION
Else
     i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(SharedFolder, apkname))
     i.SetType("application/vnd.android.package-archive")
End If
StartActivity(i)

Nothing special. But my getfileuri throw an exception in the return line.

B4X:

Private Sub GetFileUri (FileName As String) As Object
Dim FileProvider As JavaObject
Dim context As JavaObject
context.InitializeContext
FileProvider.InitializeStatic("android.support.v4.content.FileProvider")
Dim f As JavaObject
f.InitializeNewInstance("java.io.File", Array(SharedFolder, FileName))
Return FileProvider.RunMethod("getUriForFile", Array(context, Application.PackageName & ".provider", f))
End Sub

My file was here:
/data/user/0/b4a.selfupdater/files/shared/update.apk
But FileProvider.RunMethod() throw an exception:
error: Caused by: java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/b4a.selfupdater/files/shared/update.apk
Who said to them, that my file is in "/data/data/..." ?!
I had to make some change in the manifest!

Good:


It works now. But I don't know, that is some special what valid for this android device (X96mini), or valid for other type devices also?
Thanks Erel for the quick reply!
