private void updataMedia() {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)//版本号的判断  4.4为分水岭，发送广播更新媒体库

    {

MediaScannerConnection.scanFile(this,new String[]{mRecorderView.pathFile()},null,new MediaScannerConnection.OnScanCompletedListener() {

public void onScanCompleted(String path, Uri uri) {

Intent mediaScanIntent =new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);

mediaScanIntent.setData(uri);

sendBroadcast(mediaScanIntent);

}

});

}else {

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.fromFile(mRecorderView.getFilePath())));

}

}
