Android SharedPreferences after reboot device

My English very very BAD cause i'm Russian. :)

In my application I use SharedPreferences to store my values. The data has stored in the SharedPreferences, when application is running, and after exit from it. And everything works fine until I reboot my device. After reboot I can't use SharedPreferences, and the application doesn't read and write the data from there. I use the function getPreferences(0) to get preferences from application data folder. I also tried to use the getSharedPreferences(myPref, MODE_PRIVATE), but the effect is the same. Saves only one solution - data cleaning application after reboot device.

    favoriteButton = (ImageView) findViewById(R.id.favorite_button);
    SharedPreferences favorite = getSharedPreferences("Favorites", MODE_PRIVATE);
    if(favorite.getString(""+Loader.currentVideo.getTitle()+"", "") == "true") {
        favoriteButton.setImageDrawable(getResources().getDrawable(R.drawable.fav_selected));
    } else {
        favoriteButton.setImageDrawable(getResources().getDrawable(R.drawable.fav_empty));
    }
    favoriteButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            SharedPreferences favorite = getSharedPreferences("Favorites", MODE_PRIVATE);
            SharedPreferences.Editor editor = favorite.edit();
            if(favorite.getString(""+Loader.currentVideo.getTitle()+"", "") == "true") {
                favoriteButton.setImageDrawable(getResources().getDrawable(R.drawable.fav_empty));
                Loader.favoriteVideos.remove(Loader.currentVideo);
                editor.remove(""+Loader.currentVideo.getTitle()+"");
            } else {
                favoriteButton.setImageDrawable(getResources().getDrawable(R.drawable.fav_selected));
                Loader.favoriteVideos.add(Loader.currentVideo);
                editor.putString(""+Loader.currentVideo.getTitle()+"", "true");
            }
            editor.commit();
        }
    });
