Here is the structure of my program: - 2 independent modules libA and libB, each one is a single shared library libA.so and libB.so - A java activity creating 2 threads thA and thB, each one of them calling native JNI functions from one library (thA calling functions from libA.so and thB calling function from libB.so).
我想通过两个图书馆之间的土著类型数据( Java不了解任何情况,如Java能够操作的线人),但我无法找到任何途径来进行交流。
两个图书馆都知道土著类型“类型A”的定义,因此可以通过一种类型的物体。 A from libA to libB(最好不必在考试和测验记忆中复制数据)。 可以通过一个记忆点?
增 编
我在一份申请中就这样做了。 我在校正中分配记忆,并将点击器作为<条码>长期,直至通过国家情报机构报到。 然后,我打电话给B校一个功能,穿透点,以便能够进入。
However, this naive approach has problems. Although it may work sometimes, if libA and libB live on different pages of RAM, touching the pointer in libB may crash the program. The reason reported for the crash may vary on the build and run, making it a difficult situation to debug. Even worse, if the memory allocated partially resides on one page of RAM and partially on another, only when you hit the boundary you will crash whatever lies beyond, and therefore may not detect the problem immediately. I have managed to kill the OS numerous times and produce any number of various errors. If your libraries are small and loaded in adjacent memory, odds are good you will be okay. Native applications on Android can get away with things that vanilla Java apps cannot.
<>Solutions:
Passing a pointer to a typeA from A to B may be an option. It depends on the live cycle of typeA in the libraries though. Make sure that the typeA object is not deleted in one library while it s still in use in the other.
