如何在Nexus 5X上启动本机调试会话？
我尝试过运行＆＃39; ndk-gdb＆＃39;它无法启动调试会话。本机代码是使用NDK_GDB = 1构建的，部署的应用程序是可调试的。
尝试在Nexus 5X上启动gdb会话时，这是ndk-gdb的输出：

但是，在使用Android 5.0的HTC One M8上启动时，对ndk-gdb的同一调用也能正常工作。
当HTC One M8插入PC时，以下是同一应用程序的ndk-gdb输出：

Continuing.
这是Android 6.0问题还是仅仅是64位设备问题（调试也无法在Samsung Galaxy S6上运行，但我相信这是由于run-as无法正常工作）。
有没有人设法在Nexus 5X上调试NDK？
