卸载了我的应用。并且当重新安装的应用程序值不会更改时

Question

我的应用程序是一个大亨游戏，用户点击按钮以增加他的分数，因此他购买升级以增加他的快速得分。

好吧，出于好奇，我卸载了我的应用程序并通过Android Studio重新安装它，当我运行它时，应用程序无效。我试着点击按钮来增加分数，但仍然没有增加。为了保存用户分数，我在关闭应用后使用 SharedPreferences 。也许这与它有关？

Android Manifest：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.navjeevenmann.mytycoon">

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

<application

        </intent-filter>

    <activity android:name=".SecondActivity" />
