这似乎是申请不能加载libpjsua2.so库。我从来没有使用NDK的过，所以我没有对这个问题的任何想法，请帮助我...
It seems like appl cannot load libpjsua2.so library. I have never used the NDK before, so i don't have any ideas about this issue, please help me...
推荐答案
这会发生，如果你建立你的本机组件与的android-21 目标，但正在努力与较旧的Android版本的设备上运行。除非你采取非常特别的照顾，你不能运行构建与旧设备的的android-21 目标二进制文件。对于基本的C函数，它不应该不管哪个目标之间 Android版本-3 的android-20 您使用，它应该在所有的人，但如果你使用的android-21 它仅适用于该版本和更新。
This happens if you've built your native components with the android-21 target, but are trying to run it on a device with an older Android version. Unless you take very special care, you can't run binaries built with the android-21 target on older devices. For basic C functions, it shouldn't matter which target version between android-3 and android-20 you use, it should work on all of them, but if you use android-21 it only works on that version and newer.
