Hi,
I need to test USB 3.0 output bandwidth rate on Android device.
Anyone knows an app that could help with testing such issue?
Thanks

Does anyone know at what rate the accelerometer makes sensor data available for use?
For instance, is it real-time? Can I capture data from the sensor every .0001secs? Or is there a set rate?
Any information about this would be greatly appreciated.
Thanks
Hello,
I'm trying to get higher quality audio input (sample width and conditioning, don't care about sampling rate above 32k) than is available through the microphone jack and was looking for an overview of where the development of such capabilites stands today. From what I gather:
Android 3.1 (maybe 3.2) added some support for USB Audio, though I can find almost no details on the capabilities. I can't post links, but a post on computeraudiophile with google search terms "usb audio enabled galaxy s3" claims support for a bunch of USB DACs on the Galaxy S3, but there is no mention of using the ADC.
Android 4.1 added support for USB audio docks -- these are generally (as far as I can find) speaker systems with a USB cable -- which only support audio output.
Software such as USB Audio Recorder Pro can record from a number of devices but this is of no use to a developer wishing to get the data into a separate application.
Lots of devices have HDMI ports but I found nothing about anyone managing HDMI input.
I can't find any such device for Bluetooth, but also nothing suggesting that it isn't possible. If so, can anyone speculate on audio quality limitations?
Now, I understand that the vast majority of users who want USB audio want output so it can go to their speakers, but there are some who need the other direction (or both...). Can anyone more familiar with the subject comment on the state of external audio input on Android devices?
Thanks,
Ben
i have been wondering for a while now how i could make an application that is like the bluetooth voltmeter., but is capable of reading other sensors and sending the information to a gui interface program or app? i saw someone who used the headset input as a voltmeter with an app but i figure it would have to be through usb . power shoulldnt travel through the headset port but i have had chargers were it connected to the headset port? what is the reason for this?
Is it possible to output display of an Android device through USB? Let say the this Android device doesn't have a screen (just like any Android media player where it uses HDMI for display output) but now I want to use USB for display output. Is it possible? If so, could you give me some information link?

Not an option. The USB protocols don't allow for something like that
hi everyone, i use mouse and keyboard with a otg hub on my tablet, i made a polling hate test and my result was that my max polling rate is 55hz(i'm using a poor mouse) i'm wondering if i can increase this or if is a issue that i can't change, i don't know what is my mouse polling rate.
ps:i already buy a new mouse(i not with him right now)
