QUESTION
I created a file called JoyStickView which extends SurfaceView.
In my JoyStickView.java file, I have the following function which calls the AsyncTask to draw two joysticks:
ANSWER
Answered 2018-Jun-03 at 22:39You are accessing a UI element from a separate thread which is not recommended. The NullPointerException is pretty straightforward. myCanvas = getHolder().lockCanvas(); is setting a null reference to the myCanvas attribute when you are finishing the activity using the back button press.
If the code was inside your UI thread (i.e. inside any function which is in your activity life-cycle), this could have handled by the activity life-cycle functions like onStop or onDestroy. However, you are trying to change a UI element (myCanvas in your case) from a separate thread other than UI thread which is out of the Activity resource management scope. Hence the getHolder().lockCanvas() is getting a null reference for the canvas and you are getting the NullPointerException on drawing.
This can be easily avoided by implementing an interface as a listener to your AsyncTask, so that the listener function resides in your Activity and handles the resources properly. For example, you might consider creating an interface like this.

I am trying out the github examples referenced in the Affectiva AI docs.
See: Affectiva Android example on github
The examples work, shipping with the following project gradle configuration:
build.gradle
...ANSWER
Answered 2018-May-28 at 20:27Android introduced the runtime permissions feature in API level 23. An app that targets 23+ must implement runtime permissions logic and request camera permission in order to access the camera.
The purpose of the sample you are referencing is to demonstrate use of the Affectiva SDK, so to avoid the need to add a bunch of runtime permission logic which would be irrelevant to that purpose, it targets API level 22.

The basic sample project of OpenTok shows how to make a VideoCall, showing the subscribers videostream in a small frame above the publishers stream.
I'm trying to achieve the same, only vice versa. Problems:
- Simply changing the two container views in the layout xml doesnt work. What happens is, that the publisher stream (the one that should now be on top of the other stream) is not showing up (is invisble)
- This issue describes the exact problem, hinting me towards using
setZOrderMediaOverlay(true); setZOrderOnTop(true);The problem with this approach is that now the publisher stream is on top of everything, even the android gui which is not tolerable for my use case. - Using only
setZOrderMediaOverlay(true);does not work. The publisher view still is invisble.
Any idea on how to achieve this?
