Android Question Cant write to root external

[robots4life]

Hello, I am new to this software and am just learning the basics. I tried writing to the root external on my device (nexus 4) with this:

Dim textwriter1 As TextWriter
textwriter1.Initialize(File.OpenOutput(File.DirRootExternal, "random.txt", False))
textwriter1.Close

And it gives me the error that permission is denied.

I then tried dirdefaultexternal which gave me the error that no such file or directory exists which makes sense as the nexus 4 has not sd card.

Does anyone know what I am doing incorrectly?


Thanks

Both File.DirDefaultExternal and File.DirRootExternal should work with Nexus 4 (and almost all phones today).

They point to the external storage which is actually not the SD card but rather a secondary internal storage.

Have you checked project - Do not overwrite manifest file? If yes then remove this.

I did not edit the manifest. I did, however, make the manifest.xml read only before I added the textwriter segment of the code. May that be the problem?

This is the problem. You should use the manifest editor to modify the manifest file.

Yes, the checkbox should NOT be set so B4A can add permissions if a lib needs that.
