This will not help. Service code is also executed on the main thread.

Making network calls on the main thread will eventually lead to ANR errors. You can use the Threading library to make the calls in the background however it can cause other errors.

What About using a .BAS file instead a Service File ?

In my personal case:
As you can see, my game is now ANR safe. You won't be able to implement the same solution as me, but to my knowledge, your alternatives are:
- ProBundle CallSubExtended (paid)
- Threading library

Thanks Friend

But in my APP some operations depends from others.. I can't do anything Async... I need to Connect to a Host Server, to load the Databases, to Show the Tables, etc.

Is a MySQL Manager for Android..

I have too much good comments to this APP.

My APP has begun in the post 250 and today (at a month of life) is ranked 9th

I will learn too much about Main Thread.

Thanks !!

Then Friends,

What can I do ?

Can you remake your Lib DonManfred ?
Can you include an Error Management in the Wrong Connection Credentials ?

I'm sure that the ANR is for this missing feature.
