I'm working on a video recording app designed to keep recording despite interruptions (phone calls, etc.). My use case would be a user in the app pushing a button on screen to start a recording, and then at some later time manually locking the phone. I'm trying to keep the app recording video even while the phone is locked.
On devices running earlier versions of Android (tested on Android 4.1, DROID 4), the video recording keeps going when the phone has been locked. Testing on various devices, I have been unable to get the video to continue recording on any Android version past 4.1. On devices past 4.1, the video stops recording, but the audio still continues recording, while the last video frame stays on screen.
Is there any way to keep the app recording when the user locks the phone?
Basically, lock screen does not affect the working of services in an application. So if you use a service, then your recording will proceed. check out this link for more information:

You can check this article for disabling the audio in Android:

I am trying to disable screen record and screenshot in my flutter app and I already did using flutter_windowmanager package.
my problem is with screen recording, the sound of the video inside th app is still running and recorded by screen recording !
any suggestions for also preventing sound record ?
No. If your app is playing loud enough the microphone can hear it, it can be recorded. There's no way to prevent that- algorithmically canceling out sound from one source in an audio recording like that would be difficult, if not impossible. Nor would it really buy you all that much- they could always just hold an external mic up to the phone (they can also just capture your app with a second camera, which makes removing video recording also of limited use, if done to prevent a user from recording).
The one thing you could do is claim the mic yourself and not give it up. But that would be annoying to anyone actually using your app. And wouldn't rpevent capture with an external device of course.
I am trying to record audio using an app that runs WebView. For example, I load the app in the URL https://online-voice-recorder.com/ and records some audio over the mic. I have given enough permissions and able to record and replay the audio. On Windows 10, it works perfectly. But on my Android Oreo 8.1.0 running Chrom version 80, this audio is fully distorted. I tested it another device and the audio is partially legible.
Is this a standard behavior?
What I have tried to see what is the problem: I wrote a backend netcore3.1 app to play the audio and it plays the same distorted sound.
I have also tried using default sampling rates and custom and in either case, the audio remains distorted.
I wonder if this happened to anyone else so far. I am developing an app that is sending Bluetooth strings to Arduino while playing VR video. I am using Note 4 for testing and Android Studio for development.
The video and bluetooth works just fine until i put in the 4k video. It starts playing it and if not in "cardboard mode" it works. But as soon as we go to "cardboard mode", the video freezes. The voice continues to play in the background and if i go out of "cardboard mode" it continues the playback.
Any ideas to why this is happening? I have implemented VR video View just as Google suggests (from their test code). Monitor shows no errors, nothing. When i check the GPU monitor i just some really bad spikes when entering "cardboard mode", but then it just stops.
Hi everyone I recently made an application that is actually a media player of a football club ultras music. I tested it on my phone (Motorola X running Android 4.4.4) when i go back to the dashboard the music keeps playing and everything is OK. But I had a review that on Samsung Trend Plus running Android 4.2.2 the music stops playing when going back to dashboard. I didn't know what may cause this issue? any ideas? Thanx
Most likely your problem is with audio focus. On certain system, when user go to the dashboard, the launcher might take audio focus (and pause your audio play) to play its launch sound (the clicking noise or w/e). Right after that, it should hand back audio focus to you and you will need to resume your playing.
