Android Studio:“libpng 警告:iCCP:无法识别已编辑的已知 sRGB 配置文件"

问题描述

我已经从 :

dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }

到:

dependencies {
        classpath 'com.android.tools.build:gradle:1.4.0-beta3'
    }

但我收到错误:

AAPT err(Facade for 1057495093): E:\android_studio_workspace\P2JN\p2jn\src\main\res\drawable-mdpi\reload_data.png: libpng warning: iCCP: Not recognizing known sRGB profile that has been edited

编辑 buildToolsVersion 在我的 gradle 项目中:

edited buildToolsVersion on my gradle project:

buildToolsVersion "23.0.1"

那怎么解决?

推荐答案

这是一个警告，您的 png 图像有一些无效的元数据.最简单有效的解决方案是使用 pngcrush 和 optipng 实用程序.

It's a warning that you png images has some invalid metadata.Most simple and effective solution is to optimize your png images with pngcrush and optipng utilities.

运行

pngcrush -ow -rem allb -brute -reduce image.png

和

optipng -o7 image.png

在每个导致错误的图像上.

on every image that causes error.

在 macOS 和 Linux 上，您可以使用 bash 脚本查找当前目录及其所有子目录中的所有 png 图像并对其进行优化:

On macOS and Linux you can use bash script that finds all png images in current directory and all its subdirectories and optimizes them:

#!/bin/sh

for i in `find . -name "*.png"`; do
    pngcrush -ow -rem allb -brute -reduce $i
    optipng -o7 $i
done

对于 Windows，将以下内容保存到批处理文件并运行:

And for Windows save the following to batch file and run:

@echo off
set /p UserInputPath= What Directory would you like?
cd %UserInputPath%
for /r %%i in (*.png) do ( pngcrush -ow -rem allb -brute -reduce "%%i" & optipng -o7 "%%i" )

要在 macOS 上安装 pngcrush 和 optipng，请使用 Homebrew 包管理器:

To install pngcrush and optipng on macOS use Homebrew package manager:

brew install pngcrush optipng
