A crash will happen, if my shared library compiled with NDK for Android M

[ulim...@gmail.com]

 Description ：

 

1. my apk will crash，if it uses a shared library（libX.so） compiling with NDK ,  while it runs ok if the shared library compile in Android source code environment

2. the Crash stack always be same everytime，and if I add a variable Declaration in the class defined in Acodec.h(my codes), the crash stack would change.

 

3. my shared library（libX.so）is used for hardware encode/decode， and I use the API of MediaCodec (MediaCodc.h in libstagefright.so), it will be ok, and if my libX.so contains MediaCodec.cpp and Acodec.cpp, using the API of IOMX, the libX.so must crash

 

4. I decomplied the libX.so compiled with NDK and Android source code environment respectively，they are different

NDK version:

android-ndk-r10d

 

Consultation
     the difference of the defualt option of compiler in android Source code and NDK
     the reasons may result in the crash
