Android :: Detect User Idle Time
Jul 21, 2010
I would like to know if android has some kind of 'idle time broadcast message'. So for example if the user is currently using one activity of my application but haven't touched the screen or used any keyboard (and doesn't have the autolock at phone level or any screensaver) for a while, I would like to be informed (let's say after 60 seconds). I would like to avoid doing it manually (by tracking each user click, touch, activity changes...)

I would like to know if the user is using the application for the first time. I am using SharedPreferences, but I am not sure if I have the right logic. How can I set my isFirstLaunched boolean to true when the user first launches, and then immediately set to false after work has been done?
protected void onStart() {
super.onStart();
if(isFirstLaunch()){
populateDefaultQuotes();
//Save the preferences, isFirstLaunch will now be false
SharedPreferences settings = getSharedPreferences(Constants.PREFS_NAME, 0);....................

All I want to do is from time to time check my mails. For this, I want to activate the mobile network connection (3G) manually for a short period of time, and then de-activate it again.
The problem is that enabling the "mobile network" checkbox after my phone has been idle for some time, doesn't actually activate the 3G connection. (no "H" or "G" icon in the notification bar)
So when I open the mail app it complains with a "connection failed" message.
Even better would be if I could find a way to have my mails automatically checked whenever the connection is activated ...
Other than that I'm very happy with the phone.

I want a countdowntimer to halt on a menu and also when the user goes from that menu to another activity. When the user comes back from that activity or when the menu is closed, the timer should still halt. However when the user went to the home screen and clicks on the icon again, I want the timer to restart. So my question is, is there a way to detect if the user has just opened your application, or if the user comes back from another activity or menu?

Say that TaskA is currently in the foreground and my ActivityA is somewhere within its stack. Is there a way for ActivityA to get notified or detect when the user switches from TaskA to TaskB? As a use scenario, when the user launches my app, my ActivityA will always be the root Activity of the newly created Task. ActivityA will make use of Activities from other Apps, which will be pushed on the same Task. I would like to get notified when the user has switched to another application. In this case, onStop() in MyActivityA does not suffice as that will also get invoked if the user navigates to another screen within my app.

I want this same behavior even when the app is in the foreground but user doesn't interact with the app for a long-time say 6-7 mins... Assume the screen is ON all the time... I want to detect kind of USER INACTIVITY (No interaction with app even though the app is in the foreground) and kick start my count down timer.

I'm writing an application and I have a feedback screen. When the user presses submit button, it takes him to the default email client and prefills the email address, subject etc. ("mailto:") When the user presses Send, my application appears and I thank the user for giving feedback. However, how can I tell if the user has pressed the Discard button and did not send the email?

I want to detect when a user taps anywhere in a view in my Android application. My code looks like this:
linearLayout = (LinearLayout) findViewById(R.id.linearLayout); // main layout
// ...
linearLayout.setOnTouchListener(this);
// ...
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(this, "Touch!", 1000);
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Toast.makeText(this, "Down!", 1000);
return true;
}
return false;
}
but when I click on the view, I don't get Toast! Do touch events work in the emulator -- or have I got something wrong in my code?

I'm currently working on a project which requires the detection of user state (walking, running, driving), I've looked through some of the existing solutions on Android platform such as pedometer or calculating velocity with given acceleration, but I'm still unsure how I can approach this problem. Is there a way to accomplish this without much of data mining/signal processing? How can I solve this with simple logic? Or is this better solved with gps instead of accelerometer? The program will only need to return simple user-state descriptions like walking.

I would like to launch an intent when any of my activity is visible, otherwise I will put it up as a notification, and will be fired by the user. To decide this, I need to know if any of my activity is front-most, how do I that?

I have a code that will prompt user to send a message by selecting the desired application, how can I detect if the user actually have chose from the options or instead pressed Back? I tried to check if the intent returned something, but is running asyncronous so cannot be tracked. Also I have tried to run the intent with startActivityForResult, what I noticed in onActivityResult that resultCode is always 0(RESULT_CANCELED) even if user selected, or not from the chooser.

I'm trying to get an Android background service to be "notified" when the user chooses a phone number (he wishes to call) from the phone's contacts list. My goal with this is to prevent the system from placing the call and present a user with a choice dialog, then go from there.

I need to know when the user is panning the map so I can check if they've panned outside of the initial radius that I fetch data from the API with when the app launches. If the user pans outside this radius, when they stop panning I will get the new center point of the map and fetch new data with that geo-point. So far I can't find anything in the Google Maps API docs [and I've inspected the entire class tree] that notifies developers when any animation actions are occurring or completed.. It seems weird that Google wouldn't give us some sort of event listener or protected method to override on the MapView or something to do this.
I looked into what methods were available to override on the View class and it does have onAnimationEnd() but I guess panning or zooming the map doesn't count as an animation or is never passed up from the MapView or something... I tried running a simple log in onAnimationEnd() and it is never being called. Searching the interwebs gave me nothing but some never-successfully-answered posts.

Visiting www.google.com on the Android browser (or even with an android spoofed user-agent), presents the option to "Share Location". When clicked, it uses the GPS/Cell phone towers to figure out the location. I tried the google.loader.clientLocation but that only works using the IP address. Is there a method to tap into the Android OS and access GPS data from a regular web application (and not an Android application) similar to the way Google does? [Perhaps Google uses the Google Gears app on Android to access this data.]

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 be able to detect when a user types a key in the Search Dialog. I plan on using this to hook in to custom suggestion functionality.
Note: The built-in Search Manager custom suggestions functionality won't work for me because I need to customize the layout of the suggestions.

I am using a VideoView to display a video. I am using setOnPreparedListener and setOnCompletionListener to do stuff before and after the video starts and ends.
I was wondering how I could go about detecting some point of time in the video. For eg, say I want to write log to a file when the video has played for 10s. How can I detect the 10s mark?

For my site I need to be able to tell the difference between when an Android tablet visits and when an Android phone visits. It needs to be detected before the page is sent to the user so using JavaScript to check the screen res isn't an option.At the moment I use this to detect an android device: stripos($ua,'android')Is there anything unique thar a tablet has in it's user agent?
