Android :: Detect Car Acceleration In App

Jun 5, 2010

I want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well.

General :: Getting Rid Of Mouse Acceleration In Android?

Jun 7, 2014

Has discovered a way to rid of mouse acceleration in android?

Here is a good explanation of what mouse acceleration is:

Without mouse acceleration, the movement of the mouse and the movement of the crosshair will be 1 : 1.

With mouse acceleration, the movement is based on speed. Meaning, if you move the mouse 1 inch, slowly, it'll move one distance. If you move it still 1 inch, but fast, it'll move a lot farther.

Android :: Unused Java Hardware Acceleration On G1

Mar 31, 2009

Can you confirm that the G1's Qualcomm MSM7201 CPU does not support java hardware acceleration? (Re: Android game developers desperately need optimised game engine example code). I'm reading here[1]:

"528 MHz ARM11 Jazelleâ„¢[2] Java® hardware acceleration"

And from what I've read on the net, MSM7201A-a is the dual-core CPU powering the G1. So, can you confirm that Android could be faster, if Android could use the Java, instead of the Dalvik VM, and that this didn't happen because of Sun?

Android :: Inconsistency On Definition Of Sign Of X Acceleration?

Oct 4, 2009

I'm just wondering...on Android Web, I could find two completely opposite ways of defining which direction the positive X acceleration is. At the bottom, it says "When the device lies flat on a table and is pushed on its left side toward the right, the x acceleration value is positive. " However,, it says "When the device is pushed on its left side toward the right, the x acceleration value is negative (the device applies a reaction force to the push toward the left) "

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.

Android :: Detect End Of Scroll

Jun 6, 2010

I need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with neither flings nor arrow key press.

I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling animation ends.

In theory there should be a way to say that fling movement is over. Is there such API?

Android :: Detect If An App Was Uninstalled

Apr 21, 2010

Is there a way to get a system notification when an app has been uninstalled?I would like to maintain a table of all clients' info currently using my app. However, that seems impossible if there is no way to detect this event. The first solution I can think of is to have an always running service in the background listening for android.intent.action.PACKAGE_REMOVED. But then would that service be killed once the uninstallation process has ended, or would it be stopped just before the process has kicked off? Also even if this is a solution it's has the potential to put off a lot of people when they realise that part of the app is running in the background.

Android :: How To Detect Homescreen?

Jun 5, 2009

I've asked "how to detect home screen" before. I'm still searching. I noticed when I press "home" button on Android emulator, I got this statement in catalog so I went to ActivityManager to see if I can find a clue there. Here is my findings: 1. I can not instantiate ActivityManager because it's constructor is not public, and it's not a singleton 2. it has a function called: getRunningAppProcesses sounds promising -- would it give me all the running processes? 3. since I can not instantiate ActivityManager I tried to use one of the derived class: RunningAppProcesseInfo to see if I can use it's parent methods: getRunningAppProcesses. Nope.

Android : How To Detect Correctly APN Changes?

Feb 10, 2010

In my application I need to react on APN changes (including going back and forth between WiFi and GSM connections) and change proxy settings in case it needs to be taken into account to connect with the network. I'm listening for ConnectivityManager.CONNECTIVITY_ACTION broadcasts to check for APN changes which contains 'reason' extra among others. Unfortunately the 'reason' for APN change is not documented, maybe it should not be used? I was using (with limited success) reason:apnChanged and reason:apnSetupComplete as indicators of APN change being done but that does not work well with going back and forth between WiFi and mobile connection. What is the correct way of listening for changes of current network APN/Interface?
