Getting error permission write_external_storage with runtime permission

I am using permission runtime in app because android 6+ need it for dangerous permission but until force stop app my code not save file in memory even though user allow this permission in dialog.

My code for get permission runtime:

if(ContextCompat.checkSelfPermission(MainActivity.this,
                    android.Manifest.permission.WRITE_EXTERNAL_STORAGE) != 
PackageManager.PERMISSION_GRANTED ){
                    ActivityCompat.requestPermissions(MainActivity.this,new String[]{
                            Manifest.permission.WRITE_EXTERNAL_STORAGE},1);
            }else{
                saveFile();
            }

Listener for check granted or denied from user:

public void onRequestPermissionsResult(int requestCode,String[] permission,int[] grantedResult){
    super.onRequestPermissionsResult(requestCode, permission, grantedResult);
    switch(requestCode){
        case 1:
            if(grantedResult.length > 0 && grantedResult[0] == PackageManager.PERMISSION_GRANTED){
                Log.i("TAG","Permission Granted");
            }else{
                Log.i("TAG","Permission Denied");
            }
    }
}

And error logcat :

 java.io.FileNotFoundException: /storage/1B0A-390B/hamed-baradaran.mp3: open failed: EACCES (Permission denied)

SaveFile method in this :

public void saveFile(){
    InputStream in;
    OutputStream out;

    try{

        in = getResources().openRawResource(R.raw.hamedbaradaran);
        out = new FileOutputStream(Environment.getExternalStorageDirectory()+"/hamed-baradaran.mp3");
        byte[] buffer = new byte[1024];
        int length;
        while((length = in.read(buffer)) > 0)
            out.write(buffer,0,length);

        out.flush();
        out.close();
        in.close();

    }catch(Exception e){
        e.printStackTrace();
    }
}

Please help me

And try this code to saveImage

public static String SaveImage(Bitmap finalBitmap) {
    String filePath;
    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root + "/saved_images_camera");
    myDir.mkdirs();
    Random generator = new Random();
    int n = 10000;
    n = generator.nextInt(n);
    String fname = "Image-" + n + ".png";
    // filePath = "Image-" + n + ".jpg";

    File file = new File(myDir, fname);
    filePath = file.getAbsolutePath();
    //String tmpFilePath = file.getPath().toString();
    IRoidAppHelper.Log("tmpFilePath", filePath);
    if (file.exists()) file.delete();
    try {
        FileOutputStream out = new FileOutputStream(file);
        finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
        out.flush();
        out.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
    return filePath;
}
