I'm using advanced task killer to kill the tasks, and then it seems when i check back there are 12-14 apps open.It's destroying my battery. I used startup cleaner to clean up start up, hopefully that'll be useful. but i'm just trying to keep things as streamlined as possible, seems liek a lot of apps dont like to not be active

I want to hide my app screen and then when the user clicks on the app again, I want to bring it to the foreground , but I want the app to maintain the screen that was pushed to background. Is there any way to do that right now?.Because when I try to hide my app, the surface of my app is gettng destroyed and so when I try to relaunch the app a new surface is created and my app status is changing.
View 2 Replies View RelatedI have an activity which pops up a Dialog box, to get some text input from the user. The problem arises when you switch orientation. The Dialog disappears, so I have added code to set and check flags in the savedInstanceState, meaning that the Dialog is displayed again in these circumstances.I know when the window is going to be closed, but can't find a way of closing it manually. I open it with alert.show();but there doesn't seem to be any corresponding alert.destroy() method or similar.Any ideas how I can manually close the dialog box without user input?
View 3 Replies View RelatedIs there a way to keep an Activity in memory after the user hits the back button on it?ActivitySearch is used frequently in my app, however after the user starts it up, then hits the back button, it's destroyed, and the next visit to it requires it be built from scratch again.If after its first construction, I could just request it be paused instead of destroyed on the back button, then I could reuse it. Is there a sensible way of doing this?The only way I could think of reasonably doing it is to combine ActivitySearch with ActivityMainMenu into a single activity, and simply switch views when the user chooses search, but this is probably a bad design.
View 6 Replies View RelatedI'm developing a game for Android. It's got a lot going on but is running reasonably smoothly. That is, of course, until the user touches the screen.While they're touching it, onTouchEvent is called (with action = ACTION_MOVE, x = 0 and y = 0) roughly once every ten milliseconds at what appears to be a fairly high priority, as it absolutely obliterates the framerate. As soon as the touch ends the framerate returns to its nice state.Has anyone encountered this? Is there a way to reduce the rate at which ACTION_MOVE events are generated, or to ensure that they're only generated when there is actual movement, or use a polling method that just gets the current location of the touch? Or even just a way to disable it entirely?
View 4 Replies View RelatedI read up on how Android handles "configuration changes" - by destroying the active Activity.The first question I really want to know from Android Team - why? I would appreciate an explanation on how the reasoning went, cause I dont get it =)In any case, the fact that it acts in that way puts us all, as I see it, in a world of pain.Lets assume you have a Activity which presents a number of EditText:s, checkboxes etc. If a User starts to fill that form with text/data and then changes orientation (or get a Phonecall), then all input the User made is gone. I havent found any way to preserve state. That forces us to make extremely painful coding to not loose all data.
View 3 Replies View RelatedI am finding that performance degrades after one or more screen rotations, and I presume that this is likely to be because an App's main Activity is destroyed and recreated each time the screen is rotated and that my app must be leaking memory when that happens.I have read that, contrary to what one might expect, not all the objects created by an app's main Activity (or in classes called by that Activity) are destroyed when the activity is destroyed. Specifically, I think I have read (although I can't now find where) that if the View uses a large bitmap member object then the Activity's onDestroy() method should be over-ridden and the bitmap should be explicitly recycled.Are there other objects that need to be destroyed or removed when the Activity is destroyed? What about Listeners? Is there a comprehensive tutorial or guide on this subject?

View 2 Replies View RelatedMy service works exactly the way i want as long as i use start and stop and communicate using intents. However my activity needs to change the state of my service as well as retrieving state information.So i thought it would be nice to broadcast some kind of state_changed event from my service and use a binder interface to pull information from the service or change the services state based on user input.This works fine too. The only problem is that my service gets killed when i unbind it just as the documentation says.Is there any way to keep the service alive but still get an interface to control it directly. My activity offers the user a way to stop the service and the service kills itself anyway after it's work is done but i don't want the service to stop every time the activity is destroyed.

I have some requirement as given below:
I have to write an email app that should send a mail to the particular mail id.
I have written a code like this...
It is working fine, I mean sending the mail to the receiver.
But it is launching another Email app (android default app I guess). But I don't want it to be launched, I want directly send the mail to recipient.
My mail goal is that, the user should not know that the mail is sending. The default Email app (android's) should not be visible to the user. The mail sent process should be done in background.
Is there a way to 'preload' a user interfaces but to not display it until I am ready?
I have a service which has a receiver to listen for action_screen_on to occur. When that occurs, I would like to load an activity. However, as it is now, it takes about 1 second to load. I would like to preload the layout in advance so that when the screen is turned on the layout loads as soon as possible.

View 3 Replies View RelatedIn a feeble attempt to learn some Android development am I stuck at graphics. My aim here is pretty simple:Take n small images and build a random image, larger than the screen with possibility to scroll around.Have an animated object move around on it.I have looked at the SDK examples, Lunar Lander especially but there are a few things I utterly fail to wrap my head around. I've got a birds view plan (which in my head seems reasonably sane):How do I merge the tiles into one large image?t each onDraw redraw the background of the previous spot of the moving object, and the moving object at its new location
The problem is the hands on things. I load the small images with "Bitmap img1 = BitmapFactory.decodeResource (res, R.drawable.img1)", but then what? Should I make a canvas and draw the images on it with "canvas.drawBitmap (img1, x, y, null);"? If so how to get a Drawable/Bitmap from that?I'm totally lost here, and would really appreciate some hands on help (I would of course be grateful for general hints as well, but I'm primarily trying to understand the Graphics objects).
