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?

View 1 Replies View RelatedIt would appear on a G1 (with the latest software update) that onUpdate () runs even when the widget is not visible. Is there a way of sensing that the widget is or is not visible or is otherwise in foreground? That is, running the code below shows a logcat message at whatever interval the Widget is scheduled to update, whether it's in foreground or not, whether even the screen is dim or otherwise in deep sleep. It would seem onUpdate should only be scheduled to run when the Widget is in the foreground or visible. Is this a defect in the G1, or is there some other API call to detect if the Widget is visible?

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?
View 4 Replies View RelatedSay 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.

View 4 Replies View RelatedI 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.

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...)

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.

View 1 Replies View RelatedI 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 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.

View 1 Replies View RelatedI 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.]

Lets suppose that i have an activity A, that activity is moved to background(function moveTaskToBack is used), and after while i want to bring this activity to front again. This code is used: Activity A = getActivity(); Intent i = new Intent(A, A.getClass()); i.setAction(Intent.ACTION_MAIN); i.addCategory(Intent.CATEGORY_LAUNCHER); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); A.startActivity(i);
Activity is on screen, but when i invoke later moveTaskToBack on A activity, activity is not moved to backgorund. Does anyone know why?

I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)
I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.
Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)
Here is a simple test I put together that loads a game on Kongregate which has some background music:
CODE:..............
I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.
I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?
The documentation for the mobile Flash player says:
Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.
This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!
Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

I am aware my issue is against the philosophy of Android, but I have no choice, this application will run on a embedded car gps and I need to bring an activity to prevent from car accident, for example, when it's happen around the user. I have to put other activity on the back and bring my alert pop up without user manipulation like notification on the front. Is there a way to bring manually an activity to the front, by resuming it like when you click on the android task switcher?
