问题描述
目前，我有一个Android应用程序通过USB OTG连接的设备。通信是通过使用的libusb 1.0.9，它的工作pretty的以及其它设备与API级＆LT; 21。（通信必须是本机由于性能问题）当运行Android的下L时应用程序，我从libusb_init（NULL）以下错误：
I currently have an Android application connecting to a device via USB OTG.The communication is done using the libusb 1.0.9 and it's working pretty well for other devices with api level < 21.(The communication must be native due to performance issues)When running the app under Android L, I get the following error from libusb_init(NULL):
type=1400 audit(0.0:107): avc: denied { read } for name="usb" dev="tmpfs" ino=24433 scontext=u:r:untrusted_app:s0 tcontext=u: object_r:usb_device:s0 tclass=dir
A/libc(12605): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 12605 (mapp.sdk.sample)
我编译的libusb 1.0.9采用最新的NDK 10C在我的Nexus 5。我不认为这是技术运行问题，因为该应用程序的工作原理在Android 4.4.4与ART启用替代的Dalvik。任何人都熟悉这个问题？ （this类似于）可这涉及到PIE？
I'm compiling libusb 1.0.9 using latest NDK 10c on my Nexus 5.I don't think it's ART runtime issue as the app works on Android 4.4.4 with ART enabled instead of Dalvik.Anyone familiar with this issue? (this looks similar )Can this be related to PIE?
感谢你。
