titanium-mobile - libpng 警告 : iCCP: Not recognizing known sRGB profile that has been edited

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 中:

<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>

当我尝试运行该应用程序时，出现以下错误。
我正在研究 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 发出有关它们的警告。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 1.5.x 版(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)

找出是否有办法让您的应用程序将警告视为警告，而不是错误，然后这样做。
