1.之前遇到个App主页黑屏但是投屏工具或者截屏工具可以显示出来的问题，很早之前版本是可以的，于是挨个版本对比，终于查出来是在Manfest里Application关闭了hardwareAccelerated引起的，于是设置为true问题解决了。但是不久就开始报各种crash，如下

从上面log看主要错误是glViewport error! GL_INVALID_VALUE (0x501)，网上查都说是OpenGL调用Rander API不对(https://stackoverflow.com/questions/11299643/openg-gl-2-0-android-error-0x501-gl-invalid-value)，有说关闭硬件加速就可以解决，但是app默认就是开启硬件加速的，应该不会有问题。遇到此问题应该是native层出问题了。
