java.lang.IllegalArgumentException: DrawerLayout must be measured with MeasureSpec.EXACTLY.

昨天把APP装到7.0版本的华为手机后崩了，报错如图，但是之前在5.0和6.0的手机上测试都是没问题的。百度上说要重写onMeasure方法，但我试了没用，后来仔细看了报错问题，有句“ViewGroup.measureChidWithMargins”，我又去仔细看了下我的布局文件，因为我的MainActivity布局上有两个drawerlayout，一个是在外层，还有个是在viewpager的fragment里有，装viewpager的framelayout的高度我设置为wrap_ceontent，改为match_content就可以了。

附记：

之前的APP装到的6.0版本的手机上时崩了，是因为Android 6.0以后许多权限要手动获取，我的引导页里需要读取下本地数据，未获取到文件的读取权限所以崩了，手动向用户请求下权限就可以了。

Android 6.0 危险权限，此类权限需要单独申请，
