android - 代号 一个以较低分辨率运行的应用程序 (Android)

Question

我正在 Samsung Galaxy Tab A 10.1 (2019) 上测试我的应用(调试版本)。设备分辨率为 1200 x 1920。但是，当我使用 getDisplayWidth() 和 getDisplayHeight() 时，我得到 900 x 1359(= 1440 - 状态栏)。所以应用程序以较低的分辨率运行，而且图形确实看起来有点粗糙。但是当我截屏时它的分辨率为 1200 x 1920。Galaxy Tab A 没有更改屏幕分辨率的选项，我找不到解决这个问题的方法。

这是一个已知问题吗？有解决方案吗？

编辑:临时解决方案是更改(已知应用程序的)包名称。使用 NativeLogsReader.cn1lib 我们得到

1) 加上原来的包名:

--------- beginning of main
05-17 13:09:35.879 24347 24347 D ViewRootImpl@34e19e6[MainStub]: Relayout returned: 
old=[0,0][1200,1920] new=[0,0][900,1440] result=0x7 surface={true 3890690048} changed=true

2) 更改包名:

--------- beginning of main
05-17 13:22:46.459 26231 26231 D ViewRootImpl@34e19e6[MainStub]: Relayout returned: 
old=[0,0][1200,1920] new=[0,0][1200,1920] result=0x7 surface={true 3890690048} changed=true

因此，对于原始包名称，分辨率减少，而对于更改包名称，分辨率保持原始状态。我用谷歌搜索了这个问题，没有找到其他示例或线索。

编辑 3:使用原始包名称的新测试。初始情况:应用以降低的分辨率 900x1440 运行。

Steps:
1. deinstall app
2. switch off wifi/internet
3. install app (from downloads)
4. optional: switch on wifi/internet
5. run app

结果:应用的原始分辨率 1200x1920。结论:通过在线检查软件包名称在安装过程中设置了降低的分辨率。

1) 没有互联网连接:

注意 'com.xx.yy 未定义'。

2) 有互联网连接:

注意'com.xx.yy as game'。

于是就有了以包名为参数的请求https://service.game-mode.net。这使我找到了以下链接:

Display density and size reduced by Samsung Game Optimization

Galaxy Note 5: Density Reduced Automatically

https://www.xda-developers.com/samsung-shuts-down-the-game-tuner-service/

综上所述，有一个应用程序(包名称)的在线注册，在安装过程中会被查询。这可能会导致应用程序的分辨率降低。唯一已知的解决方案，即 Samsung Game Tuner 应用程序，已不复存在。

由于注册归三星所有，我问他们是否可以更改我的应用程序的状态。 (这是一个 CPU 使用率高但图形很少的游戏 AI - 当然我仍然想要高分辨率图形。)

Answer 1

导致此问题的原因是在线检查 https://service.game-mode.net (参数:包名称)在三星设备上安装期间。这可能会导致默认分辨率发生变化，例如如果该应用程序被称为“游戏”(我的应用程序是棋盘游戏)。这可以由用户使用游戏启动器等游戏性能调整服务进行更改。这适用于所有三星手机和大多数三星平板电脑。但碰巧不是我的平板电脑，三星 Galaxy Tab A 10.1 2019 (SM-T510)。联系三星开发人员支持后，他们更改了此设备类型的设置，现在我的应用程序以原始分辨率运行。
