Android Question Libraries versions and new B4A versionS.

[LucaMs]

I got a strange error (already solved but understanding the reason could be useful).

If I compile my app, which uses my SuggestionsEditText library, using B4A 7.01, I get a very strange error, the app crashes with this error message:

SuggestionsEditText was compiled with B4A 6.80 and my app does not crash if compiled using this version of B4A.

Since I'm very clever , I assumed that it would be enough to recompile the library using the latest version of B4A and in fact it works; but why that error? Obviously, ExecNonQueryBatch exists.

Also, the test project I attached along with the library (SuggestionsEditText) seems to work when compiled using both 6.80 and 7.01 (this is so strange that I have to try again!).


As I said, I don't need help, now all works, but perhaps better understanding this situation could be useful.

Maybe you compiled your lib with Java 7 and now with B4A 7 you use Java 8.
I had an almost identical error with my lib (Java, no B4A). I recompiled with Java 8 and the lib works with B4A 7.

C:\Program Files\Java\jdk1.8.0_66\bin\javac.exe

As usual I've read too quickly and superficially.

I do not know when I installed Java 8 but if I compile the library today, using b4a 6.80, I get that error (instead the app used to test the library works).

Could be this the reason?

SQL library updated to make it simpler to use with Wait For.

You need to post the full error message from the logs.

I assumed that it would be enough to recompile the library using the latest version of B4A and in fact it works; but why that error?

ExecNonQueryBatch now returns a value. This change doesn't affect B4A code, but it does affect compiled libraries as the method signature has changed. You will need to recompile the library.
