Android audio recording

The corresponding permission must be set in androidmanifest: Android: Name = "android. Permission. record_audio"

1. first determine whether an SD card exists and obtain the corresponding path

/* Check whether an SD card exists */

If (environment. getexternalstoragestate (). Equals (Android. OS. environment. media_mounted ))

{

/* Get the path of the SD card */

Mrecaudiopath = environment. getexternalstoragedirectory ();

/* Update all Recording files to the list */

Musiclist ();}

2. Start recording

/* Create a recording file. The first parameter is the prefix of the file name, the second parameter is the suffix, and the third parameter is the SD path */

Mrecaudiofile = file. createtempfile (strtempfile, ". Amr", mrecaudiopath );

/* Instantiate the mediarecorder object */

Mmediarecorder = new mediarecorder ();

/* Set the microphone */

Mmediarecorder. setaudiosource (mediarecorder. audiosource. Mic );

/* Set the output file format */

Mmediarecorder. setoutputformat (mediarecorder. outputformat. Default );

/* Set the encoding of the audio file */

Mmediarecorder. setaudioencoder (mediarecorder. audioencoder. Default );

/* Set the path of the output file */

Mmediarecorder. setoutputfile (mrecaudiofile. getabsolutepath ());

/* Prepare */

Mmediarecorder. Prepare ();

/* Start */

Mmediarecorder. Start ();

 

3. Disable recording

Mmediarecorder. Stop ();

4. Play the recording file

Intent intent = new intent ();

Intent. addflags (intent. flag_activity_new_task); intent. setaction (Android. content. intent. action_view);/* set the file type */intent. setdataandtype (URI. fromfile (file), "audio"); startactivity (intent );

 

5. filter file types to implement filenamefilter

Class musicfilter implements filenamefilter {public Boolean accept (File Dir, string name) {return (name. endswith (". Amr "));}

}
