Nexus 7中Skskivas :: drawPosText-> AutoDrawLooper :: next(SkDrawFilter :: Type)附近的libskia上的Android
作者：互联网
我最近开始在我们的应用程序中获取此SIGSEGV,并试图找出原因或解决方法.我们的应用程序仅是Java,我们不使用NDK,因此我们不会破坏内存.
这是运行4.2.2的普通Nexus 7.
该错误是间歇性的,但始终在堆栈中包含SkCanvas :: drawPosText(以下是几个完整的堆栈转储)：
backtrace:
#00 pc 01010200 <unknown>
#01 pc 0005ce24 /system/lib/libskia.so (AutoDrawLooper::next(SkDrawFilter::Type)+96)
#02 pc 0005e320 /system/lib/libskia.so (SkCanvas::drawPosText(void const*, unsigned int, SkPoint const*, SkPaint const&)+152)
我们最近进行了一项更改,导致对用作OpenGL纹理的位图进行更频繁的文本渲染(我认为是在GL线程上进行文本渲染),也许这与某种原因有关？
顺便说一句,这只是一个普遍的问题-是否有办法弄清楚哪种Java方法触发了此调用？我在堆栈中看到了各种dvmInterpret,但不知道是否有办法找出正在运行的代码.
