Android :: How To Navigate From HOME Back To A Paued Task?
Jan 21, 2009
I'm having trouble to figure out how to bring the paused Task back to foreground. As far as I understood, when I click HOME button while a task is running, the task will be paused (onPaused() of the current top-level activity will be called,right?). I think there might be a way to bring this paused task back to foreground since the task is still ALIVE, but I don't know how. Do I have to put some more codes in the activity (I mean the one that is paused)?

I am using an LG Enlighten, not as a phone but simply something to connect to hotspots with, check my email, and such things. Since I was not doing anything vital with it, I didn't put much thought into backing anything up.
Now, irritated with the default web browser, Bing and suchlike, I downloaded a bloatware remover and deleted the browser, along with two or three programs that looked like Verizon bloatware. As it turns out, one of those was my home launcher.
I did back these apps up in the program itself, but that isn't much use since I can't even access the program without a home screen.
I realized what had happened when I pressed Back to get out of the app. Instead, it went to the last app I had used. And then the one before that, and before that, and so on. I tried to keep pressing back until it would take me to the market, where I could open up the bloatware removal app and restore the backups, but eventually I came to a black screen where I could do nothing at all.
I turned off the phone, and was unable to turn it back on without performing a factory reset. Now, the phone goes to the Activation screen, and I am able to connect to USB, but that's it. The escape sequence won't bring me to the home screen - the launcher is apparently still gone.
Is there a way that I can restore the home launcher?

I have haptic feedback turned off, but the arrows you use to navigate the home screen still vibrate, as well as the luck buttons and widgets. Is this normal, or is this an issue? Also while in low light, or dark conditions, shouldn't the for hard keys light up?? Is this an issue if they don't, or just an affect of not having brightness set to auto?

Whenever I am using any app and press the home button, the home screen blacks out for a few secs and it takes around 10 sec to get all the icons back and before I can start using my phone again. I am using a non rooted mytouch 3g.
This problem does not happen if I exit an app by pressing the back button. It becomes very annoying at times.

Ive had open home downloaded for over a month and i only used it for a short period of time before switching back to the default homepage setting. Now, because of the new features added to Open Home i want to switch back, and every time i open 'Open Home' it only opens until i hit the home key. Then it does not ask me what i want to use as my default as it used to. I went to settings>applications>manage applications>open home to clear all defaults but it is not highlighted for me to select it. How can i set Open Home to my default again?

Is there a way to tell when my task gets put on the back of the UI stack (user pressed "home" say?) I have some resources I'd like to free when not foregrounded. The lifecycle routines seem dicey to use to try and infer this. The "home" key does not seem to be passed to onKeyDown(), and moveTaskToBack() is never called by the system so I can hook it. I can poll the ActivityManager for running activities with my task id, but hard to find a good time to call this.

My application has two activities, that I start in this order: HOME > A > B Now I press HOME and launch "A" again. I would like to see activity "B" on a top of "A", but instead I get "A" - so the activity stack is cleared. Manifest: <activity android:name=".activity.A" android:label="A" android:always Retain Task State = "true">What should I do?

I am just starting on an Android app and I am puzzled about why my Task activity stack is being reset any time the application is launched from the Home screen. I used the ADT tools to create the application in Eclipse. The main activity is ".UserLaunch" and it starts the activity ".About" when the user presses a button. If the user then presses HOME and then relaunches the app, .UserLaunch is displayed and is the only thing on the stack.
.UserLaunch has the launchMode singleTask. .About is standard. According to the documentation at http://developer.android.com/guide/topics/fundamentals.html#lmodes: "However, a "singleTask" activity may or may not have other activities above it in the stack. If it does, it is not in position to handle the intent, and the intent is dropped. (Even though the intent is dropped, its arrival would have caused the task to come to the foreground, where it would remain.) "The Task stack should be brought to the foreground and .About should still be displayed. I added Logging to all of the lifecycle events (edited to remove timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can see that when HOME is pressed, .About cycles through onPause and onStop (as expected). Then when the app is again launched, .About is destroyed and .UserLaunch is restarted D/UserLaunch:(670): onCreate() D/UserLaunch:(670): onStart() D/UserLaunch:(670): onResume() I/ActivityManager(52): Displayed activity com.cequint.cityid/.UserLaunch: 4910 ms I/ActivityManager(52): Starting activity: Intent { comp= {com.cequint.cityid/com.cequint.cityid.About} } D/UserLaunch:(670): onPause() D/About(670): onCreate() D/About(670): onStart() D/About(670): onResume() I/ActivityManager(52): Displayed activity com.cequint.cityid/.About: 1031 ms D/UserLaunch:(670): onStop() I/ActivityManager(52): Starting activity: Intent { action=android.intent.action.MAIN categories= {android.intent.category.HOME} flags=0x10200000 comp= {com.android.launcher/com.android.launcher.Launcher} } D/About(670): onPause() D/About(670): onStop() D/dalvikvm(670): GC freed 413 objects / 34128 bytes in 72ms I/ActivityManager(52): Starting activity: Intent { action=android.intent.action.MAIN categories= {android.intent.category.LAUNCHER} flags=0x10200000 comp= {com.cequint.cityid/com.cequint.cityid.UserLaunch} } D/About(670): onDestroy() D/UserLaunch:(670): onRestart() D/UserLaunch:(670): onStart() D/UserLaunch:(670): onResume() Here is the relevant section of the Manifest: <application android:icon="@drawable/icon" android:label="@string/ app_name"> <activity android:name=".UserLaunch" android:label="@string/app_name" android:launchMode="singleTask" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".About" android:launchMode="standard"> </activity> </application> Anyone have any ideas why this is always resetting the Activity Stack?

When I DL'd the GDE app, I accidentally set my stock droid "HOME" screen as the default screen when the popup box came up asking me to choose between stock Home and GDE. Now when I click on GDE and click the home button, it switches back to the stock Home screen. How to I switch the settings now to set the GDE app as the new home screen?

One of the best features IMO of Home++ was not having the task bar visible at top of screen. I really liked just having the scrolling toolbar at bottom. Recently the task bar at top has shown back up. Anyone else experiencing this? Was this part of a recent update that I didn't pay attention to until just now?
I still really like Home++, even with that bar, just prefer not to have it.

I took of Advanced Task Killer when I put Fresh and Gumbo on since some have said that they don't play nice. I sometimes mess up and don't close out the app by hitting the back button. My phone starts to warm up and the battery starts draining. How do I see what apps are running so I can close them out so that I don't kill my battery? Can I put Advanced Task Killer back on?

According to previous screen shots before buying evo yesterday, the home screen gmail envelope has a green circle with # of unread messages but while testing out and sending multiple messages from my desktop to myself, it just shows in the task bar and not on the gmail envelope. Am I missing something her?

I set my screen to use HOME versus Sense UI. Well, I put the ATM widget on my screen for single click app ends...when I do this, though, it kills home.
Anyway I can exclude Home from this. It doesn't appear to be an option in my Apps list when i open Advanced Task Manager
I have YET to receive a single email from androidforums.com when I use "Instant Email Notification" for thread replies.

This has been brought up before, but I was unable to find a satisfying answer. And I know it's a newbish question.
What is the difference between exiting an app with the back button compared to the home button? I am not talking about switching to the home screen, I am talking about a scenario when you want to exit an app. For example, you play a game, you're done - do you press home or back? Or, you're in the Facebook app and you want to exit to the homescreen - what do you press - back or home? At first, I thought both buttons do the same with the difference that home brings you to the homescreen instantly while back goes through your previous steps/pages/screens in the current app and then returns you the homescreen.
But later I noticed that 'reactivating' some apps that were exited via the back button cause them to 'reload' (the loading screen shows up - with certain games, grooveshark's loading screen, etc.) while they switch back instantly when "exited" with the home button.
I gather the way to 'leave' an app you don't plan on using for at least a short while (I am not talking about closing the app, I know it's up to Android, or some task-killer) is the back button, while home is more for task switching/starting new apps while old ones are running.

My application is composed by several activities,I would like to give the user the option to go back to the home screen of my application by pressing a button on the screen.At the same time I can't call the finish() function on activities between the home screen and the currently visible activity because by pressing the back button the user will go back only one step and see the previous activity.Any idea on how to achieve this?Is it possible to access the activity stack and e.g. close all the activities it contains except the first one?

Say a user runs my app from the HOME screen. The app has 3 tabs. Say he/she selectes a different tab, so he/she is in a different screen (same task). Now - if the user presses BACK - the device returns to the HOME screen. If the user launches my app again - the default tab is shown. BUT - if the user presses HOME - the device returns to the HOME screen (same). If the user launches my app again - the OTHER tab is shown.
I understand (sort of) the logic - BACK returns to previous app, popping my app from the history stack, so when launched again - it is started from scratch. But this is confusing my customers - they say it's a bug ! They dont understand the different between two keys doing the same thing as far as they see (returning to HOME). Moreover - I see a different behavior with the built-in DIALER app - I change tabs, press HOME, launch the app again - and it starts with the default tab.

I am writing a count down timer, using .postdelayed(), that speaks each second as the timer goes down to zero. I have trouble understanding the consequences of the user hitting the back or home button.
The countdown continues when hitting either button. When home is pressed and you reclick the app, it goes back to the same count(this is what i always want) and continues to count down. When you hit the back key and then reclick the app, you get a new clock that has not started but I still here the sounds from the original timer. How can I code an app so it only can have one instance and chicking the app icon will always go to the active version if it is running?

I am working on a device that does not have a hardware Home, Back or Menu button. I am trying to create a soft keyboard with only these three keys but I have not been able to get it working. Does anyone have any insight into my problem?
I first looked into injecting keypresses into a WindowManager but this functionality seems to have been removed.
I then looked at creating a custom soft keyboard but that will not work either. Custom soft keyboards only inject their input into the text fields they are attached to. I can't send a Home, Back or Menu keypress to the Android system.
I finally got the Home button working by using this intent to tell Android to go to the Home screen: Intent HomeIntent = new Intent(); HomeIntent.setAction(Intent.ACTION_MAIN); HomeIntent.addCategory(Intent.CATEGORY_HOME);
Unfortunately, I have not found an Intent to send for Menu and Back.

I would like to know how could i block the dial, home , back and the end call button on an android device.
I know this is possible because there is an application : TheftAware which does block all the buttons so they have no effect at all.
And I also would like to know how to make a dialog window or any kind of window which would stay on top no matter what (this is also done in theftaware).
They are also able to block(hide) the call screen... does someone know how are they doing that ?
Does all this means that android is not that secure after all ?

I have a device with no hard buttons, on which I need to get Android running. The basic port is done, but I need to provide access to Home, Menu, and Back. The Archos tablets put soft buttons in the status bar, and I'm told that the android-x86 folks have implemented this as well (though I haven't found it in their source yet).
