为什么我的SharedPreferences项不被重新安装时清除？(Why are my Share

在重新安装我的if语句中我的应用程序代码被尽管尚未已经建立了我的SharedPreferences进入访问。我使用的是日食的模拟器，它需要的数据被清除比重新安装一些其他的方式？谢谢

prefs = getSharedPreferences("appData", 0);
        Gson gson = new Gson();
        String gsonStr = prefs.getString("playerString", null);

        if(gsonStr != null)
        {
            //This code is being accessed on the apps first onCreate() call prior to being reinstalled 
            Player[] tempArray = gson.fromJson(gsonStr, Player[].class);
            Log.d("First Player", "" + tempArray[0]);
        }

protected void onPause() 
{
    super.onPause();
    if(savedPlayers != null)
    {
        Gson gson = new Gson();
        String gsonStr = gson.toJson(savedPlayers.toArray());

        prefs = getSharedPreferences("appData", 0);
        SharedPreferences.Editor editor = prefs.edit();
        //editor().clear();
        Log.d("GSONString",gson.toString());
        editor.putString("playerString", gsonStr);
        editor.putInt("ArraySize", savedPlayers.size());
        editor.commit();
    }
}
