我的安卓平板连钢琴不成功,折腾了一天搞掂。希望能帮助到大家。 连接安卓成功有两个条件:1. android 4.0以上 2. 安卓平板支持usb host 我的联想平板不支持usb host。我是参考这里解决的:http:///questions/11183792/android-usb-host-and-hidden-devices 转帖在这里: To enable USB host API support you should add a file named android.hardware.usb.host.xml and containing the following lines: <permissions> <feature name="android.hardware.usb.host"/></permissions> into folder /system/etc/permissions in that folder find file named handheld_core_hardware.xml or tablet_core_hardware.xml and add <feature name="android.hardware.usb.host" /> into <permissions> section. Reboot your device. Usb host api should work. 另外一种方法是在平板下载运行“usb host check”,它会自动做上面的工作。 两种方法都需要先root安卓。 |
