ndk crash in constructor

在這篇post有講到
http://groups.google.com/group/android-porting/browse_thread/thread/5e1464ad78aaab5f

如果code在constructor就掛掉的話
在trace dump裡是看不出結果的

得要把notify gdb跟call cstor順序調換一下

早期的renderscript是在eclair時的 libacc

不過最特別的是renderscript號稱 portable 跟 performance
不過心裡還是抱著很大的問號就是了

另外也有些地方不太了解
C++ on the other hand was very desirable but ran into issues with portability. The advanced C++ features are very difficult to run on non-cpu hardware
這裡的c++ advance feature 是什麼??

 For example, some compute hardware can support pointers and recursion while others cannot
什麼hardware會沒support pointer 跟recusrion呢??
