ProcessEngines.getDefaultProcessEngine()
return me null when I try init a new process in activiti engine.
Do you know what could be the reason ?
Taken from the Activi forums user frederikheremans:
As stated in the Javadoc for ProcessEngines, this class is used by a
ServletContextListener, which calls the ProcessEngines.init(). The
init() will scan the classpath for activiti.properties an tries to
build a ProcessEngine for each file found.
The getDefaultProcessEngine() only works [if] the ProcessEngines.init()
has been called (by
org.activiti.impl.servlet.listener.ProcessEnginesServletContextListener
or by calling it yourself once) and if a process-engine with name
'default' is available.
The OP of the thread I got that from stated that he too received null from getDefaultProcessEngine. Hope that helps.

Imagine I have two async methods and a main method. In the main method, one is called in line of code 1 and another in line of code 2. I want the code to be blocked in line of code 3 because I need the results of those 2 methods.
Is this possible in Spring Boot? What could I use?
You can use completableFuture.

CompletableFuture.allOf() or CompletableFuture.join() ll help;

How to get value of Thread-local from current Thread?
I am trying to get the value of Thread-local from current Thread but can't find any help online.
Read the Javadoc for ThreadLocal. There are only 4 methods on ThreadLocal; the one you need is obviously ThreadLocal.get():
Returns the value in the current thread's copy of this thread-local variable.

So the question is basically if to have
getDriver().findElement(by).clear();
or to have
String text = getDriver().findElement(by).getText();
if (!text.equals(""))
getDriver().findElement(by).clear();
and after that a sendKeys.
Note: Most of the times, the field is empty.
This is simple math
getDriver().findElement(by).clear();
Costs as
getDriver().findElement(by).getText();
To the second line you add an if check and maybe getDriver().findElement(by).clear(); anyway.
So just call clear() without a check.

I have loadGraphics() function in my app. It takes a lot of time to be executed. I want to make loading screen, while this function is running. Can I create inside callback, which would have notified me about the function succeeds? Thanks in advance.
Yes. Just create a private boolean that can only be accessed in the class, setting it to false initially. Before beginning that loadGraphics(), just start a basic thread that has a callback in it if that boolean is true.
Then just add a statement at the end of loadGraphics() that sets the boolean to true.

So I got this bit of code http://pastebin.com/RMh4eHLq from the Android dev blog (modified) but when I try and call it via
ImageDownloader.download(image, image_main, image_table);
it tells me to change the download modifer to static but if I do that the ImageDownloader class tells me no portion is accessible. Any ideas?
Have you tried with:
ImageDownloader imgDwn = new ImageDownloader();
imgDwn.download(image, image_main, image_table);
