wish helps you First of all: I searched for my question in StackOverflow. , You should pass context to shared_level class via the constructor.
code :
public class shared_level {
    private Context context;

    public shared_level(Context context) {
            this.context = context;
        }
    ...
}
final shared_level shared_level = new shared_level(yourActivity.this);

I wish this help you Sending shared preferences through intents seems overcomplicated. You could wrap the shared preferences with something like the below and call the methods directly from your activities:
code :
public class Prefs {
    private static String MY_STRING_PREF = "mystringpref";
    private static String MY_INT_PREF = "myintpref";

    private static SharedPreferences getPrefs(Context context) {
        return context.getSharedPreferences("myprefs", 0);
    }

    public static String getMyStringPref(Context context) {
        return getPrefs(context).getString(MY_STRING_PREF, "default");
    }

    public static int getMyIntPref(Context context) {
        return getPrefs(context).getInt(MY_INT_PREF, 42);
    }

    public static void setMyStringPref(Context context, String value) {
        // perform validation etc..
        getPrefs(context).edit().putString(MY_STRING_PREF, value).commit();
    }

    public static void setMyIntPref(Context context, int value) {
        // perform validation etc..
        getPrefs(context).edit().putInt(MY_INT_PREF, value).commit();
    }
}

Hope that helps The shared preferences are accessible throughout your application, so you can read them from any activity in the application.
Storing a key/value pair in activity A:
code :
SharedPreferences settings = getSharedPreferences("mysettings", 
     Context.MODE_PRIVATE);

SharedPreferences.Editor editor = settings.edit();
editor.putString("mystring", "wahay");
editor.commit();
SharedPreferences settings = getSharedPreferences("mysettings", 
    Context.MODE_PRIVATE);
String myString = settings.getString("mystring", "defaultvalue");

This might help you I am trying to share a shared preference in between two activities of my project, but for some reason I am not able to pass the data. , You can do simpler - in any activity:
code :
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);

may help you . You can use Singleton pattern to implement global access to the SharedPreferences. Something like this:
code :
    public class SharedPreferencesManager {

    private static final String APP_PREFS = "AppPrefsFile";
    private static final String KEY_FOR_SOMETHING = "KEY_FOR_SOMETHING";

    private SharedPreferences sharedPrefs;
    private static SharedPreferencesManager instance;



    private SharedPreferencesManager(Context context) {
        sharedPrefs =
                context.getApplicationContext().getSharedPreferences(APP_PREFS, Context.MODE_PRIVATE);
    }


    public static synchronized SharedPreferencesManager getInstance(Context context){
        if(instance == null)
            instance = new SharedPreferencesManager(context);

        return instance;
    }

    public void setSomething(String something) {
        SharedPreferences.Editor editor = sharedPrefs.edit();
        editor.putString(KEY_FOR_SOMETHING, something);
        editor.apply();
    }

    public String getSomeKey() {
        String someValue = sharedPrefs.getString(KEY_FOR_SOMETHING, null);
        return someValue;
    }
}
SharedPreferencesManager.getInstance(context).getSomeKey();
