I am making an app which allows users to record audio clips and access them. I am trying to save the recorded audio files inside a custom folder in my gallery.
I have a function that creates a File and sets its location:
private File getOutputMediaFile(int type) {
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + "dirName" + File.separator);
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
return null;
}
}
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"IMG_" + timeStamp + ".jpg");
} else if (type == MEDIA_TYPE_VIDEO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"VID_" + timeStamp + ".mp4");
} else if (type == MEDIA_TYPE_AUDIO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"AUD" + timeStamp + ".WAV");
}
else {
return null;
}
return mediaFile;
}
I use getOutputMediaFile
to save recorded audio file like so:
audioRecorder = new MediaRecorder();
audioFilename = getOutputMediaFile(MEDIA_TYPE_AUDIO).getAbsolutePath();
//more code
audioRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_AUDIO).getAbsolutePath());
When I log audioFilename
, I get the following path: /storage/emulated/0/DCIM/folderName/AUD20160425_172620.WAV
I am able to save and play the audio file, but with a caveat:
gallery/myFolder
; I can only view the audio file if I run the default play music
app and look inside "my playlists". I have the following permissions in my manifest:
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.RECORD_VIDEO" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
What am I doing wrong?
I guess we need to tell MediaStore that "a new file is created". Try this:
public void refreshGallery(File file, Context context) {
Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
scanIntent.setData(contentUri);
context.sendBroadcast(scanIntent);
}
