如何在android studio中存储用户选择的铃声？

Question

public void onRingtone(View view) {
        final Uri currentTone= RingtoneManager.getActualDefaultRingtoneUri(Setting.this, RingtoneManager.TYPE_ALARM);
        Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_RINGTONE);
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Ringtone");
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, currentTone);
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);
        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
        startActivityForResult(intent, 999);
    }

I have this onClick method to select available Ringtone from it's own device. When startActivityForResult() method is called it redirects to custom popup dialog from where user can select a Ringtone and at same time it starts that Ringtone. That's Ok. But I want to save that Ringtone to play it on another activity. So what should I do? Can I store it in database(SQLite), or in SharedPreference or any other way?

Edit: I don't know why my question got closed even if I provided all information. But still giving more information, to understand my question better.

Xml file:

<RelativeLayout
                android:id="@+id/Ringtone"
                android:layout_width="match_parent"
                android:layout_height="60dp"
                android:layout_below="@id/sp2"
                android:layout_marginTop="1dp"
                android:background="@drawable/pressed"
                android:clickable="true"
                android:focusable="true"
                android:onClick="onRingtone"
                android:gravity="center"
                android:paddingTop="15dp"
                android:paddingBottom="15dp">

The above method is called when the user selects the Ringtone. I got one answer which told me to use SharedPreference to store uri. I want to keep the selected ringtone even after app gets closed. So SharedPreference is a better option but how to make it global so other activity can also use it?

If I create object of SharedPreference in this java file, how can I get access to other acivity?

To save ring tone Uri , you can use:

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("currentTone", currentTone.toString()); 
editor.commit();

To retrieve ring tone Uri you need to parse the string to Uri :

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
String currentToneString= settings.getString("currentTone", null);
Uri currentTone= Uri.parse(currentToneString);
return currentTone;
