Writing files in Android KitKat?

Question

Android

I opened my old project, before my application created files in the following way:

final String FilesFolder = Environment.getExternalStorageDirectory().getAbsolutePath()
                                                + File.separator + "Android" + File.separator + "data" + File.separator
                                                + this.context.getPackageName() + File.separator + "files" + File.separator;

File creation

final File imageFile = new File(FilesFolder + (inputData[0].type == ImageProvider.ImageSizeType.FULLSIZE ?
                        "images" + File.separator + imgFileName : "image_miniatures" /*+ File.separator*/ + imgFileName));

permissions are written in the manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

In Android KitKat, this method does not work - writes access is denied.
