libusb版本：libusb-1.0.20

Ubuntu： 14.04

NDK：android-ndk-r9d

測(cè)試手機(jī)：三星S4

開發(fā)板：GD32

==================

?

Building:

---------

?

To build libusb for Android do the following:

?

1. 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-build".（需要設(shè)置環(huán)境變量或者使用絕對(duì)路徑）

?

The libusb library, examples and tests can then be found in:

"android/libs/$ARCH"

?

Where $ARCH is one of:

armeabi（測(cè)試使用此架構(gòu)，armeabi-v7a未測(cè)試）

armeabi-v7a

x86

?

Installing:

-----------

For a rooted device it is possible to install libusb into the system

image of a running device:

?

1. Connect the device to a machine running ADB.

?

2. 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 /sdcard/libusb1.0.so

?

?

Test:

-----------

1. new project file

1) 任意目錄下mkdir libusb_for_android

2) 在libusb_for_android/ 添加libusb1.0.so、libusb.h、usbtest2.0.c，并且新建jni目錄

3) 在jni/ 新建Android.mk和Application.mk

?

2. 在jni/下運(yùn)行：/opt/android_ndk/android-ndk-r9d/ndk-build

在libusb_for_android/libs/armeabi/下即可找到產(chǎn)生的可執(zhí)行文件usbtest

?

3. 將usbtest adb push到手機(jī)的sdcard/

?

4. 將開發(fā)板和手機(jī)相連，然后再手機(jī)的超級(jí)終端下運(yùn)行:./usbtest

?
