We have to developed an Multimedia Application, should record audio and playback and video as well,
i googled, and it seems, Audio capturing is not supported in Android Emulator,
Is this correct, Is there any way, i can test it on the Emulator.
Also i am starting with Samsung Galaxy Tab as an Android Virtual Machine, please let me know if this is correct way to start.

I've written a Android module for an App which required a way to make a voice recording. The app is cross-platform and thus required a way to record and play cross-platform, the only problem is that a recording made with a Samsung device doesn't play on iOS but other devices (OnePlus 3 & Nexus 7) do play on iOS even though there is no difference in the way the file is processed as far as I know. Does someone have experience with this or is able to help me out?
I want to use an audio capture feature at my app. I followed this link at developer.android.com.
I'm using Android Studio 1.4 and a Nexus 5 with Api21 as virtual device. At developer.android it is descripted that it's not possible to use the audio capture feature with an simulator:
Note: The Android Emulator does not have the ability to capture audio, but actual devices are likely to provide these capabilities.
But is this an information that is up to date? I'm able to use the record button but the activity crashes after pressing stop. I can see the audiorecordtest.3gp file on the simulated device and if I save it to my computer I can play my recorded audio. The crash comes without any shown exception. If I ask for
context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_MICROPHONE);
I got back a true. It seems like the simulator is able to capture audio but can't handle correctly the stopping of it? Is there a way to get around?
One aspect of Tamper Checking involves testing for an Emulator running your app...
In THIS article (Paragraph 4.1), Emulator detection is described... The tests detect many emulators, but throw some "false positives", depending on the device.
False positives render some emulator test's, described in the article, not appropriate for production, but are fine in a test environment where you know your devices and their test responses.
Based on previous thread, getUserMedia is supported in Chrome on Android now (version 40).
I got this working using the usual getUserMedia idiom (see, for example, http://www.html5rocks.com/en/tutorials/getusermedia/intro/).
This works on desktop (any mic) and on mobile (default mic).
However, when a USB mic is plugged in, this does not seem to work. The usual permission dialog is shown. However, the input audio will actually come from the phone's default mic (ie, scratching/tapping the usb mic produced no noise), even though the USBmic is clearly connected (ie, it lit up).
On desktop, you can fix this by selecting the audio input source, but I'm not sure how to do that on Android.
The really funny thing is that typical audio recording APPs can actually CORRECTLY get the audio input from the USB mic on the same device.
Has anyone experienced this problem?
I can reproduce this issue it appears to be specific to some Android phones and Android tablet devices that I have tested, including a Samsung Tab A7 and the Amazon Fire 10".
Currently testing Samsung Tab A7 with Chrome 103.0.5060.129 Android 11; SM-T220 Build/RP1A.200720.012
I do not have this issue in chrome on my Android Oneplus 8 running Android 11.
More information for reproducing:
The expected behavior does not work in Chrome, but does work as expected in Firefox.
Plug in an external USB microphone device
Open a site such as https://vdo.ninja/ or a https://www.webrtc-experiment.com/
Capture audio.
The default audio will be captured from the devices internal microphone instead of the USB microphone.
On sites such as the vdo.ninja, where you are able to select the audio source, even if the source is listed, such as "Wired Headset", changing the input will result in using the internal microphone.
My Android application is targeting non-rooted Samsung Galaxy Note 2 phones running Android 4.4.2.
When my USB microphone is plugged into the phone, it appears as /dev/snd/pcmC1D0c, so I know it is being recognizing as an audio capture device.
Is there a way to capture the Audio from this device into my app without rooting the Galaxy Note 2?
I tried AudioRecord with all the MediaRecorder.AudioSource options and they all use the phone's internal mic.
I did not find any option in Settings/Sound to change the input device.
I investigated Samsung's Professional Audio SDK and it looked very promising until I found the Galaxy Note 2 device I am targeting is unsupported by this SDK.
If there is no way to access it from Java, is it possible to use native c code (JNI) to access the existing tinyALSA driver and capture the audio without rooting the phone?
I know I can use use libusb to capture the audio packets directly, but I was hoping for an cleaner/easier way since the phone already recognizes my audio input device.
I am developing few multimedia solution, for same I am dealing with Camera, i Have webcam but there are some limitations in android so that I cannot use it in emulator.
Now my question is, how android play sound, I could hear mp3 files from android emulator, how speaker is accessed through Android ?
Please do the needful,
