Android Question Threads

[Semen Matusovskiy]

Hi, guys --

In my app activities and services change process global variables.
Under Windows all is simple - mutexes, semaphores, critical sections etc. But what about B4A ?

Somehow Erel wrote that it's not neccessary to lock something, because B4A use one thread only.
Meanwhile I worry about common executing of activities, from one side, and services, from another side.

I made a simple experiment - main activity and Starter service have the same process and threed id (I checked android.os.Process.myTid and android.os.Process.myPid)
Is it correct that it's not nessesary to worry about locks at all ?

All your code runs on the main thread. Many tasks are asynchronous which means that they are executed with background threads, however the events are raised again on the main thread.
