Download the latest NDK from: - http://developer.android.com/tools/sdk/ndk/index.html - - 2. Extract the NDK. - - 3. Open a shell and make sure there exist an NDK global variable - set to the directory where you extracted the NDK. - - 4. Change directory to libusb's "android/jni" - - 5. Run "$NDK/ndk-build". - -The libusb library, examples and tests can then be found in: - "android/libs/$ARCH" - -Where $ARCH is one of: - armeabi - armeabi-v7a - x86 - - -Installing: ------------ - -If you wish to use libusb from native code in own Android application -then you should add the following line to your Android.mk file: - - include $(PATH_TO_LIBUSB_SRC)/android/jni/libusb.mk - -You will then need to add the following lines to the build -configuration for each native binary which uses libusb: - - LOCAL_C_INCLUDES += $(LIBUSB_ROOT_ABS) - LOCAL_SHARED_LIBRARIES += libusb1.0 - -The Android build system will then correctly include libusb in the -application package (APK) file, provided ndk-build is invoked before -the package is built. - - -For a rooted device it is possible to install libusb into the system -image of a running device: - - 1. Enable ADB on the device. - - 2. Connect the device to a machine running ADB. - - 3. Execute the following commands on the machine - running ADB: - - # Make the system partition writable - adb shell su -c "mount -o remount,rw /system" - - # Install libusb - adb push obj/local/armeabi/libusb1.0.so /sdcard/ - adb shell su -c "cat > /system/lib/libusb1.0.so < /sdcard/libusb1.0.so" - adb shell rm /system/lib/libusb1.0.so - - # Install the samples and tests - for B in listdevs fxload xusb sam3u_benchmark hotplugtest stress - do - adb push "obj/local/armeabi/$B" /sdcard/ - adb shell su -c "cat > /system/bin/$B < /sdcard/$B" - adb shell su -c "chmod 0755 /system/bin/$B" - adb shell rm "/sdcard/$B" - done - - # Make the system partition read only again - adb shell su -c "mount -o remount,ro /system" - - # Run listdevs to - adb shell su -c "listdevs" - - 4. If your device only has a single OTG port then ADB can generally - be switched to using Wifi with the following commands when connected - via USB: - - adb shell netcfg - # Note the wifi IP address of the phone - adb tcpip 5555 - # Use the IP address from netcfg - adb connect 192.168.1.123:5555 - -Runtime Permissions: --------------------- - -The default system configuration on most Android device will not allow -access to USB devices. There are several options for changing this. - -If you have control of the system image then you can modify the -ueventd.rc used in the image to change the permissions on -/dev/bus/usb/*/*. If using this approach then it is advisable to -create a new Android permission to protect access to these files. -It is not advisable to give all applications read and write permissions -to these files. - -For rooted devices the code using libusb could be executed as root -using the "su" command. An alternative would be to use the "su" command -to change the permissions on the appropriate /dev/bus/usb/ files. - -Users have reported success in using android.hardware.usb.UsbManager -to request permission to use the UsbDevice and then opening the -device. The difficulties in this method is that there is no guarantee -that it will continue to work in the future Android versions, it -requires invoking Java APIs and running code to match each -android.hardware.usb.UsbDevice to a libusb_device.
