Android :: Detect The Usb Device
Dec 11, 2009
I have ported the Android to a x86 platform. And i want to detect the USB plug-in.But follow the information about the android.intent.action.MEDIA_MOUNTED in the SDK's DOC, i can't receive the event of the USB's plug-in. i have checked my code and it can receive the other event ( ps:intent action) .
Besides, in the CLI, i could mount the USB device to /sdcard but it couldn't mount automatically. have seen some source code about the mount and mountlistener and it should be effective. my SDK's version is 1.5.

Is there a way to detect the device model of a user through Java code on Android? To return htc-magic or htc-dream or something like that, somehow? I have been trying to detect this through the user agent when the client is accessing an web page, however this is always Java0 through Android. Has anyone done this? Any ideas?

On Launch of the application, I want to detect if the device running is rooted. Is there proper way of detecting it? I don't think trying to write a file to 'data' to see if rooted is a good solution.

Is it possible to detect whether the android device has moved in a certain direction and how much it has moved? For example, if I move my device 100 pixels to the left, a number would be displayed saying x is -100 pixels. If this is possible, which sensor would I use?

Is there a simple way to detect that your code is running on the android emulator and not on a real device? I want to work around differences between emulator + real, e.g. with respect to network connectivity detection.

Is there any way in Android to determine whether a device is running Sense UI? I'm working on an app that is working fine with vanilla Android, but Sense UI is messing with layouts and sizes. I'd like to be able to see whether the device is running Sense UI and so I can take appropriate action.

I would like to know if and how it is possible to detect if my application have run in the past on a given android device. I would like every time the phone reboots to be able to check if my application has run on the past and retrieve some private data. If not just create those data.

I'm writing a software that checks events in user's calendars and does some manipulations over them. But I would like to touch only those events which are present in synced calendars only. I'm using Google Calendar API, but don't know how to list only synced calendars and ignore others.

I need to use my phone as emulator/target/virtual device when I run my application. I have installed HTC Sync and the USB driver is in order. I have enabled the USB Debugging in Settings. What more do I need to do to make Eclipse AVD Manager to detect my phone?

I've got an app that needs to handle Android versions 2.2.1 and above differently than 2.2. I'd rather not create two separate apps, but I haven't been able to find a way to identify what version of Android is running on the user's device.

I would like to ask, what are some of the core files that wifi depend on to be able to work?
And what permissions are set for those files? I am using a Cowon Z2 which runs on Android 2.3.5, and it suddenly stops detecting hotspots. It just keeps scanning endlessly with no hotspots. My Nexus S can detect and connect still.
I tried a couple of things like, removing the data/misc/wifi/wpa_supplicant.conf file to allow it to generate a new file, but it still fails.
know what are the files I should see to ensure that wifi works.
OR
How do I know if my wifi hardware is dead?

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.

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'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 would like to have my code run slightly differently when running on the emulator than when running on a device. (For example, using 10.0.2.2 instead of a public URL to run against a development server automatically.) What is the best way to detect when an Android application is running in the emulator?
