General :: Emulating HID Device?
Feb 19, 2013
I'm developing a solution that allows one to use a PC keyboard+mouse to control an Android game (e.g Shadowgun) as a Gamepad.
I want to do this via emulating an HID device connection (as one would connect a real gamepad), but instead I want to inject my own events to this virtual device. there is a shocking amount of material and I'm not quite a kernel/linux professional.
For example, injecting events to the touch input subsystem is easy: just write appropriate events to /dev/input/event2.

I was wondering if it would be possible to emulate touch controls with a USB keyboard similar to how you can emulate touch controls with a PS3 controller using the sixaxis app. I want to do this for some rhythm games.

I am trying to develop a device which would attach to my Droid and send keystrokes to it, but I need help understanding how the USB OTG works. I have the basic pinout, but is there a reference and instruction set guide anywhere, preferably with example code? Has anyone had any luck developing similar peripherals?

Basically I have an old iPod touch 2g on iOS 4.x and a Nexus 5.
I want to use my iPod as my media player but I'd like to be able to control music from my Nexus (only basic controls).
Is there an app on either device that allows this? I know tsk skipping can be done by some Bluetooth headphones so I'm hoping there's a way to make iOS accept command from my Nexus

I have 3 Galaxy Player 5 ( YP-G70 with 3 capacitive buttons ), only one of the actually have a working rom that i flashed a while ago.
The other two have a different rom that only have the back and menu button working ( the home button doesn't respond )
Is there a way for me to take the Rom and kernel off the working galaxy player so i can install it into the other two ?

Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

I have developed and tested my app on the emulator, and now want to install it on my HTC device. the apk installs successfully, however my database is not going with it. I have created my database using sqliteman browser b/c I have to insert a bulk data before the app starts. I have four tables in my db and call each in different activities and created all on the sqliteman. after the data is inserted I pull back the db onto the data folder of the emulator. it works perfect on the emulator but failed on the device. when I try to pull my db on the real device, it shows access denied problem

How do I map the device Y axis to the screen Y axis?I can't figure this out.I'm the developer of Tricorder, and I'm trying to make it so that the accelerometer and magnetometer indicators I draw always point in the right direction.On the G1 phone with the slider closed, all is well.But when I open the slider, I end up showing that gravity is pulling me to the left (if the phone is held with the display vertical).So, I know that the device, and hence sensor, Y axis is always in the direction of the earpiece; and the screen Y axis changes when I open the slider.And I know that I can use remapCoordinateSystem() to change the device axes to match the screen axes.But where do I find out what the device's orientation is?In other words, how do I compute the correct values for the X and Y parameters to remapCoordinateSystem()?
Configuration.orientation seems quite useless.Suppose it is set to LANDSCAPE.What does this mean?Does it mean a device which is "naturally" portrait (i.e. the sensor Y axis points to the narrow end), and which has been turned into landscape mode?If so, which way was it turned?Or does it mean a device which is naturally landscape?In other words, LANDSCAPE could mean that the screen axis is off from the sensor axis by +90, 0, OR -90 degrees.Not much help.So how do I do this?Obviously I want my app to work on all devices, not just the G1 phone.

I have a standalone GPS enabled data recorder in my car that can function as either a USB host or device. (Its a class 0x00h USB device). I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.

I'm using the android plugin for eclipse, and when I try to run my program using a real device through the android device chooser, my phone is not listed as a device. I have updated eclipse and all of the android packages, but it still isn't showing up. My phone is running 1.6, which is also the target version listed in the eclipse project.Also, the reason I decided to try testing on a real device is because the emulator doesn't seem to be working right anymore when I run my project. The emulator launches, but the program never does. Any ideas?(using windows 7/t-mobile mytouch 3g)

I updated a popular word game and the new version simply doesn't work. I've waited a few weeks and no update. This is on my tablet and I still have the older version on my phone. How can I copy the older version from the phone to the tablet? Or can I? Neither are rooted and I can't seem to find where the file is stored.

I came from WEBOS and ROOTING a device meant typing a string into the device and the Superuser icon will show up.
In and Android device I would like to know what exactly the rooting process is doing. Is it turning on a icon? is it actually creating the icon? is it different for different devices? etc

I've just started looking into porting ROMs (more specifically, ICS themes to Gingerbread), and I found a few tools that port the ROM for you. If it were really that easy, isn't it possible to port any ROM to any device?

As I was nervously trying to install a custom rom, i wipe everything off my device ( HTC Desire X ds ), as per required by the instruction. But before in could install the rom, the device shut itself off. Now I can't even start it on bootloader, it just simply display a black blank after a short htc logo appears. Then after a while it vibrate 7 times in a row.

I'm new to Android (LG Optimus S) so maybe I'm missing something but I downloaded a lock screen widget today - and I can't uninstall it to save my life. I am not totally ignorant, I read the special instructions to remove the widget as a device administrator and tried that first but it just lets me select Deactivate but does not actually deactive, it stays as an administrator no matter what I do, so then the app won't uninstall.
