shrinkResources设置为true，但所有未使用的资源（特别是可绘制）未被删除 [英] shrinkResources set to true, but all unused resources (specifically drawables) not getting removed

问题描述

我将shrinkResources设置为true，如下所示：

I'm setting shrinkResources to true as follows:

releasepro {
    minifyEnabled true
    shrinkResources true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    applicationIdSuffix ".pro"
}

但是这只消除了一些未使用的资源。我知道，gradle会做一些猜测，并留下不确定的资源是否未使用。有没有办法删除所有未使用的资源100％？

But this is removing only a few unused resources. I am aware that gradle does some guessing and leaves resources that is is not sure are unused. Is there a way to remove all unused resources 100% ?

我读过关于在另一个线程中将shrinkMode设置为strict的方法。这会有帮助吗？我无法尝试，因为我无法确定它在哪里设置。查看示例和文档，但很遗憾，无法进入正确的页面。

I read about setting the shrinkMode to strict in another thread. Will that help? I could not try it as I could not figure where to set it. Looked for examples and documents but unfortunately could not get to the right page.

有没有办法确保100％清除未使用的资源？

Is there a way to ensure 100% removal of unused resources?
