libpng 警告：iCCP：无法识别已编辑的已知 sRGB 配置文件

Question

我正在尝试更改 Titanium android 应用程序中 TextField 中光标的颜色。 为此我创建了platform/android/res/values/ 文件夹。

我将以下代码放在tiapp.xml：

<android xmlns:android="http://schemas.android.com/apk/res/android">
  <manifest>
    <application android:theme="@style/Theme.Titanium">
    </application>
    <uses-sdk android:minSdkVersion="22" android:targetSdkVersion="22"/>
  </manifest>
</android>

当我尝试运行应用程序时，出现以下错误。 我正在开发 3.4.1。 API 级别仅为 22。

Answer 1

正如警告所说，您有一堆带有无效颜色配置文件的 PNG 文件。 Libpng16 发出关于它们的警告。您的应用程序将警告视为错误。

要解决此问题，您可以执行以下一项或多项操作：

• 使用 PNG 编辑器从列出的 PNG 文件中删除 iCCP 块 在错误报告中，例如，使用 ImageMagick 的“convert -define png:exclude-chunk=iCCP,zCCP"

• 使用 PNG 编辑器删除所有辅助块，例如 convert -strip

• 将您的 libpng 降级到版本 1.5.x（当前为 libpng-1.5.23）

• 使用“-DPNG_sRGB_PROFILE_CHECKS=-1”重新安装 libpng-1.6.x（当前为 libpng-1.6.17）

• 了解是否有办法让您的应用程序将警告视为警告而非错误，然后执行此操作。
