关于Android中的shrinkResources的一个奇怪的错误

Question

shrinkResources在build.gradle中被标记为true。

然后我发现了这个奇怪的错误：

在我的应用程序的java文件中，有一行如下：

String unit = String.format("%%s %s", getResources().getString(R.string.XXXX));

请注意%%s %s

中有空格

如果我添加这个空格，我的一些PNG将被ShrinkResources标记为未使用的资源，并且不会被打包到apk文件中。

但如果我省略了空间，一切都很好。

对我而言，这简直令人难以置信。它会让我疯狂......对此有什么看法？

更新

试图让我的问题更加明确：

如果我的java代码是

String unit = String.format("%%s %s", getResources().getString(R.string.XXXX));

然后部分输出（实际上我在resources.txt中找到了它）：

Skipped unused resource res/drawable-xxhdpi-v4/head02.9.png: 822 bytes (replaced with small dummy file of size 77 bytes) Skipped unused resource res/drawable-xxhdpi-v4/appointment_normal.png: 1827 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/cg_normal.png: 1850 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/pre_normal.png: 1822 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/doctor_normal.png: 1963 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/infor_normal.png: 1605 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/btn_check.png: 716 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/btn_check.png: 898 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/navigation_arrow_left_normal.png: 184 bytes (replaced with small dummy file of size 67 bytes) Skipped unused resource res/drawable-xxhdpi-v4/dameon_killed.png: 913 bytes (replaced with small dummy file of size 67 bytes)

不会显示跳过的png。

如果我的java代码是

String unit = String.format("%%s%s", getResources().getString(R.string.XXXX));

没有我上面发布的输出，一切都很好。
