It was working fine. Maybe I need to enable something on my Android device?
My Android device is connected now to the PC via USB and working fine.
When I'm running my program in debug mode and touch the screen it never stop on:
#Override
public boolean onTouchEvent(MotionEvent event)
{
float eventX = event.getX();
I added a break point on the line: float eventX = event.getX();
But touching the screen does nothing.
You are not at all registering the OnTouchListener. First register OnTouchListener using anonymousclass or just implements it in your class
From your code you need the listener for this SingleTouchEventView view. Just add "implements View.OnTouchListenter" for the class. Because you have already overridden onTouch method in your code.
You have to change your style.xml when you remove "Extends ActionbarActivity"!
Check this change appTheme

I have the following code that runs in a service where it captures screenshots from Android. What technology could I use to send a remote command to this service to execute the task? I don't want it to run from a MainActivity button. Firebase cloud messaging ? Websocket ?

I have successfully built a python server which even works but when java from android studio tries to connect to it fails with whole bunch of errors. I have understood that it fails while creating a new socket object but why that I don't know.
This is Java client, see at the end of the code particularly for the issue where I have created new Socket object:

This is my python server code:

print("Socket successfully created")
try:
port = 24224
s.bind(("", port))
print("socket binded to %s" %(port))
except socket.error as err:
print('Bind failed. Error Code : ' .format(err))
s.listen(10)
while True:
conn, addr = s.accept()
print('Got connection from', addr)
message = conn.recv(1024)
print("Client : " + message)
conn.close()

So this is my code.
And when I try to build my apk or debug the project I see the following error:

You need to add HttpClient as project's dependency. Here you will have details on Grade/Maven dependency that you will have to add to your .build or .pom file
https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient/4.5
I have the following code which is working without any errors, but I get this
Skipped 116 frames. The application may be doing too much work on its main thread.
That happens when I press the Single button and the init() method is executed.
How can I execute the method in another thread so it won't break like that ?

Thank you
You are doing the Bluetooth related calls on the UI thread and you blocking the UI thread with these calls.
I have an app that uses a system of plugins. These "plugins" send out a broadcast message which my app then receives and uses the relevant data attached to register the app.
The issues is that I dont know how many plugin are installed on the device at any given time, so I dont know how many messages to wait for, and I don't know of any way to check to see if its the last message being sent.
Right now I'm kinding faking it by waiting for a three second timer to finish, allowing three seconds for the plugins to register, but as more plugins are developed, this isnt going to be enough time.
How can I refresh my UI only when all of the plugins have finished registering?

How can I refresh my UI only when all of the plugins have finished registering?
By definition, it is not possible. You need to revise your plugin system so that either:
You "know how many plugin are installed on the device", or
You do not need to wait (or even really care) at any point "how many plugin are installed on the device"
