libpng警告:iCCP:无法识别已编辑的已知sRGB配置文件

Question

我想在Titanium android app中改变TextField中光标的颜色.为此,我创建了platform/android/res/values/文件夹.

我将以下代码放入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.

正如警告所说,你有一堆PNG文件具有无效的颜色配置文件.Libpng16发布有关它们的警告.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编辑器从错误报告中列出的PNG文件中删除iCCP块,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libpng降级到1.5.x版(目前为libpng-1.5.23)

• 使用"-DPNG_sRGB_PROFILE_CHECKS = -1"重新安装libpng-1.6.x(目前为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,并执行此操作.
