can the android emulator play audio

Question

I wanted to record and pass through the recorded sound to the phone\'s speaker, but I could not get the recording code to work (app crashes, SEE MY ATTEMPT HERE) so I am now

Answer 1

Yes, you can do audio related work on emulator.

Your code sequence should be -

mp1 = new MediaPlayer();
mp1.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp1.setDataSource(PATH_TO_FILE);
mp1.prepare();
mp1.start();

And for setting permissions in the manifest file.

Use these for record feature-

and these for playing feature -

There is a guide article on official android developer website

Guide to audio capture and Guide to media playback

and if it dosn't work, then post your log cat screenshot.
