kandi X-RAY | cameraserve Summary
CameraServe is an Android 2.3+ (API level 9) application that allows older (as well as newer) devices to remain useful by becoming IP cameras. The app engages the Android device’s camera and listens for connections on a configurable port (default 8080). A web browser or any number of standard IP cam [monitoring apps] can connect and view the images as an MJPEG (Motion JPEG) stream.

QUESTION
I have a really strange issue. I have an android app with some imagebuttons. When you press the imagebuttons (depending on which imagebutton) the app navigates to a new fragment using the JetPackNavigation. Basically I have been using the app (while developing it) for more than 4 months and the navigation had never been a problem.
Now all of a sudden when clicking some imagebuttons the app in the App Emulator of Android Studio does not react anymore. This is really strange because I did not change anything (I made sure by using the local history of Android Studio). Further for some ImageButton it still works perfectly.
So my question is bascially, whether there is a way to find out what causes the problem? In the logcat there is no error message whatsovever. I only get a timeout report after some while without any hint, as you can see here
...ANSWER
Answered 2021-Jan-10 at 12:24This answer is the synthesis of the discussion we had in the comment section which eventually led to a solution.
Before we do anything in such a situation, it is vital to double-check whether there was some change after all that we did not see for some reason. It is important not to omit this double-check, because this does not take much time, while the systematic approach that leads to the solution involves a lot of effort. So, with this double-check we have a lot of potential gain with virtually no risk/cost. I personally use git as a version control system, but any system that is reliably showing such differences will do the job.
Seeing many not working image buttons looks overwhelming, we need to focus our research to a manageable and understandable problem-space. So, we need to choose one of the not working image buttons and find out why that does not work. If we are lucky, then solving that problem will either automatically solve the others, or give us some strong hints for the others. Naturally, we could have multiple very different problems, which off course means that we need to repeat the process outlined in this answer.
A very important hint is that not all the image buttons show this behavior, so we know that the problem is unlikely to be related to image buttons and it's more likely related to actions triggered by events on the image buttons.
Some debugging and logging is always helpful. Debugging shows us what happens, so if we do debug, we might find some bad behavior at some point which might well be the issue itself. If we do some logging, then we can see what happens while the program is running. We can do either or both.
In some cases there is no solution. For example a remotely working API might stop working, which is an unsolvable issue. In this case detecting this situation is vital. If there is no solution, then at least we need to find this out as quickly as possible, so we do not sweat on it too much.
Some steps towards the solution:
- Reduce the problem space to a small, manageable size (and possibly provide more information into your question)
- Define your problem well (Currently you link your problem to image buttons, but you are wrong to do so, since the fact that some image buttons work disproves the hypothesis that image buttons would work wrongly)
- Look into the undivideable units of work, in your case the actions, choose one of them as a current focus and redefine the problem into an even smaller size)
- Log and debug to collect information
- From the list of the information you have collected plan a few experiments
- Sequentially try all your hypotheses
- If the solution is not yet found, then you might start all over from point 1. or you might decide to remove the action (temporarily) and gradually implement it back, until you either find what the problem is or accidentally solved it

QUESTION
I'm profiling an app in android which makes use of the camera. I'm seeing a high CPU usage of two processes /system/bin/cameraserver and mm-qcamera-daemon I would like to know what are they used for and if both of them are required by the camera.
...ANSWER
Answered 2019-Jun-16 at 16:38cameraserver is the Android service for the camera
mm-qcamera-daemon is a proprietary thing from Qualcomm, according to https://www.spinics.net/lists/linux-media/msg26901.html it is polling the driver (which can explain high CPU load)
If your device is using Qualcomm SoC, you need both
QUESTION
How to get a full list of the Android native servers. To be specific I ask about Android 7.1.2. I try a several approaches but in my opinion both of them are wrong.
First:
...ANSWER
Answered 2017-Aug-15 at 10:26By 'native' people mean 'written in native platforms language' this means C/C++ for android. A service usually means 'object in memory that has exposed binder interface'. Where other processes can call it's IBinder derived interface. So in example that audioserver from ps list it's a server started by init.rc on boot, it's written in C++ you can call it a native server. It has at least 2 services inside: audio_flinger and audio_policy - they are also C/C++ code, they are objects that expose it's IBinder interface so you can call them 'native services'.
a list of all services is here: adb shell service list
some inside runtime info if you like to runtime debug:
adb shell dumpsys
A list of servers/deamons you do it correctly - 'ps' but not all of them like 'rild' or mentioned 'surfaceflinger' has a server in its name.
Read your /system/core/rootdir/init.rc plus device///init*.rc in your android source directory.
