问题描述
我最近偶然发现了一个问题与Android 4.0.3，其中林尽快得到以下异常在应用程序启动（在其他Android版本，它工作正常）：
I have recently stumbled upon an issue with android 4.0.3, where Im getting the following Exception as soon as the application starts (on other android versions it works fine):
java.lang.NullPointerException

这涉及具有硬件加速启用，只要我禁用它在清单中的应用程序开始工作就好了。
This is related to having hardware acceleration enabled, as soon as I disable it on the manifest the application starts working just fine.
这样做搜索，我发现一个登录（里面那个文档搜索上罗曼盖伊的一些谈话，在那里他讨论什么可能会造成这一点，虽然目前还没有解决方法或修复提出了drawPatch），我不知道我是否应该禁用硬件加速仅为此版本的Android ，或者如果有解决方法吗？
By doing a search I found a log (inside that doc search for "drawPatch") on some conversation of Romain Guy, where he discuss a little bit of what could be causing this, although there is no workaround or fix proposed, I wonder if I should disable hardware acceleration only for this version of android, or if there is a workaround for it?
感谢您的时间。
推荐答案
所以AC提到这在他的评论，但让我解释。
So A-C mentions this in his comment but let me elaborate.
您可以创建一个值文件布尔值和坚持在正确的版本的文件夹。在您的清单下
看看这篇文章： https://plus.google.com/+AndroidDevelopers/posts / DcsFABkyuYM 。
You can create a boolean in a values file and stick it in the correct version folder. In your manifest under
Check out this post: https://plus.google.com/+AndroidDevelopers/posts/DcsFABkyuYM.
看起来你会想目标值-V15 / bools.xml
Looks like your going to want to target values-v15/bools.xml
