format of strings

[hackhack]

Can a string hold characters from 0 to 255 ascii?

When the http library talks about reading things into 'strings' does that include binary files?

You should not use strings to hold binary data. You should use a bytes array.
Strings cannot hold all the possible values. Strings are much more complicated as they hold Unicode code points.

Aww, the old days are really gone, eh.

Ok 2 questions:

How do i write them to a file then? Seems there is only file.WriteString not WriteBinary

And, byte arrays can't be open ended right? You have to dim their size in advance of using them?

 

[Erel]

You can use OutputStream or RandomAccessFile to write the data. What are you trying to do, maybe their is a simple way to do it?

I'm trying to download an apk from a website, and once downloaded start the install to allow the user to update the app.

I tried just launching the browser to the URL, and that sorta works, the apk gets downloaded, but I'm not sure if the download would always be in the same place. I can't be sure of the name necessarily, and I don't know how the app would know when the browser had finished. So I thought I should try and download it myself (so to speak)

This should not be too difficult.
You are using HttpUtils, right?
To copy a file you should use code similar to:

Dim out As OutputStream
out = File.OpenOutput(File.DirRootExternal, "1.apk", false)
File.Copy2(HttpUtils.GetInputStream(...), out)
out.Close

Yes, I saw you said that was the easy way

To copy a file you should use code similar to:

Dim out As OutputStream
out = File.OpenOutput(File.DirRootExternal, "1.apk", false)
File.Copy2(HttpUtils.GetInputStream(...), out)
out.Close

Thanks, I'll try that.

See B4A-Bridge source code for an example of installing a saved apk: Basic4android Search: B4A Bridge source code

Your example code further up worked excellently
