Android :: How To Lock Down Device
Feb 10, 2009
I am developing for an event marketing company that wishes to have event staff use the device with android at events and capture data from people with an app I'm gonna write. What I want to know is if it is possible to lock down the device, e.g. disable the dialer, messaging, not allow them to run programs we don't want them running, etc, because the event staff can't be trusted. The only solution I found so far was to make my own home screen app and set it as default home app and not display the programs/settings in this app and remove shortcut keys. But incoming calls will still bring up the dialer, text messages will still bring p messages program, etc. If you cant disable or lock dialer, messages, etc., is there a workaround?

Currently I can have playback controls on the lock screen of my idevices, as you can see in the screenshot below. Pandora is one example on when I would use this. How can do this same thing on my android device? I currently have a Galaxy Tab 2 7" & I'll be getting the GS3 soon.

So two days ago while i was in the gym, i dropped a dumbbell and unfortunately it landed right on my Driod Razr M. So the screen has no functionality what so ever, i cant reset it or anything, broken. It was rooted and I loved all my settings on it. I have a pattern unlock for it and such, however, USB debugging is disabled (worst thing ever, second to it breaking) So i want all of my data off my old phone and into my new one. Is there anyway from my laptop that I can get all of my data off it and onto my new Driod Razr M? Any way i can bypass my pattern lock, and get everything back?

Is there anyway to disable the initial swipe lock screen and replace with the pattern lock? Seems silly to have a double lock.....the pattern seems much better to me.

I am plan B and AVG security installed, both don't always work, I have pattern lock on the phone but even in pattern lock mode when i press and hold power button the phone gives me option to shutdown.
If someone steals my phone they will be able to shut it off without unlocking it since holding down power button still works. So is there a way to lock the power button from shutting off phone when the phone is in pattern unlock mode?

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

Is there a way to have a phone lock on the Desire, in the way it is used on "normal" phones? What I mean is that I need a phone lock for security reasons - however it is a pain to use it every time I turn the screen on. Is there a way to have it work only when you turn the phone on? Right now if yu don't have a phone/screen lock security set if someone steals your phone they take out the sim card and use the phone normally ... if you do have it, then you must use the password every time you want to use the phone (I hate it). I know the best thing is to have a secured access but I was just wandering if it was possible to do seomething different?

We recently purchased the Moment for my daughter, she has had the phone for 2 days. It seems she does not remember the lock pattern and we have not signed up yet for a gmail account. We have tried holding the left and center button then holding the right after a battery pull but when the progress bar comes up(grey) it goes a little over halfway then stops, it never finishes. I have done a search and came up with nothing else. She has 2.1 if that helps.

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 donīt know if this is the right place to report bugs, but there it goes:
Android: 1.5 Phone: Samsung Galaxy Firmware: Any
I found an annoying bug when the screen stops locking, and the workaround is to restart the phone or restart the dialer application. This bug happens when you use a SIM card that changes the dialed number (there are SIM cards that inserts a operator code automatically in the number) Steps to reproduce the bug:
- Activate "Auto insert operator code" feature in your SIM card (usually in "SIM Toolkit") - Make a distance call (without the operator code) - It will show a dialog in screen saying "Number changed by SIM card" or something similar - You donīt have to complete the call. From this point, if you try to lock the screen, it just turns off the LCD, but the screen is not locked (if i press any button the phone goes on, unlocked)

Im having a problem where my eris answers calls when its in my pocket. I carry my phone in my front pocket and any lock app that Ive tried does not keep it from answering in my pocket. the default slider lock doesnt work, its simply way too easy to move the slider down, especially while in your pocket. if the phone stops ringing before you slide it down, the screen is still activated with a missed call notification, so the slider is still there. the pattern lock isnt an option because it doesnt apply to incoming calls.
A lot of these lock apps just dont work because you can unlock them by hitting the soft keys, or they dont apply to incoming calls. is there a lock app that only works with the hard keys or the trackball?
Im looking for a lock app that will replace the default slider so I cant activate it in my pocket and that will keep it locked down after a missed call. any developers out there interested in working on this? I think something similar to the iphone slider would work, as long as it applies to incoming calls and cant be unlocked with any other key.
