android - Android 4.2 cache error

Question

I have this error when i try to :

File file = new File(cacheDir, fileName);
Bitmap bmp = BitmapFactory.decodeFile(file.getAbsolutePath());

cache dir is from :

context.getCacheDir();

And the error is:

11-30 12:38:34.029: E/BitmapFactory(18814): Unable to decode stream: java.io.FileNotFoundException: /data/data/com.android.test/cache/file_name: open failed: ENOENT (No such file or directory)

This is my void to write the file:

public static void writeFile(Bitmap bmp, File f) {
        if (bmp == null)
            return;

        FileOutputStream out = null;

        try {
            out = new FileOutputStream(f);
            bmp.compress(Bitmap.CompressFormat.PNG, 80, out);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (out != null)
                    out.close();
            } catch (Exception ex) {
            }
        }
        Log.i("app", "path: "+f.getAbsolutePath());
    }

In this void, the Log.i in the end print the same file path as the error one.

I have this error ONLY on device with android 4.2. till android 4.1.x all works fine.
