新創建的聲音文件，我創建了一個文件，並用它來保存我的聲音文件，但不能在音樂的Android無法找到音樂
File f;
boolean recording=false;
public void startStopRecording(View view){
try {
if (!recording) {
do {
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = new Date();
String filename = "rec_" + dateFormat.format(date)+".gpp";
outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myRec/"+filename;
f = new File(outputFile);
f.getParentFile().mkdirs();
}while(f.exists());
myAudioRecorder = new MediaRecorder();
myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
myAudioRecorder.setOutputFile(outputFile);
myAudioRecorder.prepare();
myAudioRecorder.start();
recording=!recording;
}else{
myAudioRecorder.stop();
myAudioRecorder.release();
myAudioRecorder = null;
recording=!recording;
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(Uri.fromFile(f));
sendBroadcast(mediaScanIntent);
MediaScannerConnection.scanFile(this, new String[]{f.getAbsolutePath()}, null, null);
}
} catch (IOException e) {
e.printStackTrace();
}
}
我也試過這個可以添加文件，還是不行
ContentValues values = new ContentValues(4);
long current = System.currentTimeMillis();
values.put(MediaStore.Audio.Media.TITLE, "audio file");
values.put(MediaStore.Audio.Media.DATE_ADDED, (int) (current/1000));
values.put(MediaStore.Audio.Media.MIME_TYPE, "audio/3gpp");
values.put(MediaStore.Audio.Media.DATA, f.getAbsolutePath());
ContentResolver contentResolver = getContentResolver();
Uri base = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Uri newUri = contentResolver.insert(base, values);
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, newUri));
如何將我的聲音文件添加到音樂？
