I have an app that allows you to record short voice memos. Some users aren't able to record any audio(LG Ally being one device) at all. I'm using the MediaRecorder in android and am curious if there might be a "better" standard way to handle audio recording?

I have a project where I want to implement live audio stream from users with Android phones in my LAN Network and receive them in my laptop, off which I can filter, reduce noise, control volumes of each and write the audio to the speakers.
Please help. If possible Android and Java.
I am implementing automatic call response application in android.In my application the call is respond by the audio file which is recorded by user and that file will play when incoming call is answered automatically by program.I have searched for it to know how to do this but all are saying that this is not possible in android to play audio file during call.So, I want to know what are the alternatives that can be used for doing the same thing.
According to android official docs, it is not possible to play audio while a call.
See the docs here :https://developer.android.com/guide/topics/media/mediaplayer.html
Note: You can play back the audio data only to the standard output
device. Currently, that is the mobile device speaker or a Bluetooth
headset. You cannot play sound files in the conversation audio during
a call.
As an alternative you can use Twilio : https://www.ipragmatech.com/play-audio-file-android-call-using-twilio/
Before I even attempt to write this android app, I need to know if its possible to do the following with the standard Android SDK library or any known 3rd party library.
Output audio from multiple simultaneuosly playing files to both the wired headphone jack AND bluetooth A2DP at the same time.
Each file/output combination will have its own volume control in the app as well. So if the volume on file 1 is turned down on the headphones but not the bluetooth volume, it still can be heard on a bluetooth speaker but not in the headphones. Same would apply on file 2,3,4 etc
I am rather new to Android development but I wish to receive audio and video content on my phone from a pc. I am trying to record gameplay on my pc, and do not have the money to buy the hardware recorder, and I can not do screen capture and maintain acceptable fps.
What I had in mind was to send my screen and audio to my phone like a second screen, where my phone will handle the saving process, reducing cpu load on my pc. I don't think android phones can receive hdmi output, but I can do this with the USB via the android adb library "pull" command. However this requires that the file already be saved.
I can't seem to find any other way to do this, can anyone recommend a library I could use?
No. USBs are slow. And there is no way to transfer what's on your computer screen to your android device without first recording it on the computer itself and then having to pass through the slow USB device and then slowly writing it to your phone's hard drive. You'll be recording at a solid 0.5fps by then.
On Android, you can record audio from the microphone using the MediaRecorder class:
MediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
I want to record some parts of audio being played by a MediaPlayer instance instead (or some other audio playback device). Is that possible? How would I set a custom audio source?
To summarize; how do I stream audio into the MediaRecorder from an arbitrary audio source?
I don't think there is an API for that for now. Though it IS possible, you would have to have access to the device's buffer, down to the kernel/hardware level. Even if you find a way, I don't think Android would give you permission to do this on application level.
