[android-developers] Why does it have the same and correct response for USB devices at all Android mobiles or PAD?
Dear Sir: I use USB Device Info App to test usb multi-devices by some Android mobiles or PAD Below is my steps 1. USB Hub with plugging 3 usb the-same devices 2. plug into Galaxy Nexus 3. Open USB Device Info App and switch to Android Page 4. unplug one usb device in order out of USB Hub(finally unplug all devices) 5. plug usb device in order into USB Hub(finally plug into 3 devices) 6. unplug USB Hub out of Android mobiles or PAD Below is my test devices and its response 1. Galaxy Nexus(with Android 4.0.3) = App will show normally 2. Galaxy Nexus(with Android 4.2.2) = It will hold USB-Hub message after unplug USB Hub, if repeat plug/unplug it hold many messages for USB-Hub 3. Nexus-7(with Android 4.1.1)/Galaxy S2(with Android 4.0.4) = It can't detect USB-Hub, so no-device can't found. If plug usb device directly into Nexus-7/S2, it can be detected Do you have any idea for this condition? Why does it have the same and correct response for USB devices at all Android mobiles or PAD??? Because they have the same and correct response, I can't use USB-HOST API to find correct devices Thank you for your advices BR, Alan -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to screen capture through fb0?
Dear Sir: I use screencap to get and it works well, but change screenshot to fail I study source code of screencap, and it uses ScreenshotClient class that passing through SurfaceFlinger to work well, but screenshot that using /dev/graphics/fb0 can't work How do I recognize the GPUs can work when using screenshot? Thank you! BR, Alan On 2月15日, 上午5時39分, Dianne Hackborn hack...@android.com wrote: This has never been guaranteed to work, because GPUs may not be able to give access to the frame buffer like that. Even in the cases when it did work, it could be corrupted since there was no control over the state of the frame buffer when reading it. This is why there is a shell command to do this, which DDMS uses, and is updated appropriately for the platform. Use the shell command. If you are running on 3.0+ and writing system code (which means you are posting to the wrong group anyway) you can use the mechanisms for that... but put this discussion in an appropriate group like android-porting.
