[Espinosa4]

Hi,

I've just compiled with the b4a 6.5 my program and when I try to install in a mobile with another version Android system give an error.


can you help me please to fix it?

Starting with Version B4A 6.50, if you compile with 6.50 and already have an older app, you need to first uninstall the older version app and then install the new one with 6.50 version. You only do it once to that older app.

Hi Mahares,

and the tables? will be deleted

 

[Mahares]

If the tables are in File.DirRootExternal, they are safe, but if in DefaultExternal or Internal, you need to make copies of the database first, otherwise, they are deleted when you uninstall the old one.

Thank you Mahares!

I have the tables defaultexternal.
I'll install an old version of B4A for continuing working with that version.
Thank you

Cheers

The debug key was changed in v6.30. You can use the old one if you like: https://www.b4x.com/android/forum/threads/conflicting-signature.71219/#post-452635
