I'm developing on Android. I have to restart home and all its components (widgets, shortcuts, etc..).
For example, when we have a Force Close, the home screen restart and reload all its components.

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?
View 2 Replies View RelatedMy Android app Transdroid offers several home screen widgets. Every AppWidget has 2 'buttons' (ImageButton), one starts the app and one starts some activity that refreshes the AppWidget content. Pretty simple. Here is a screenshot.The problem is: the widget's onUpdate is not called after the Home process is restarted, and hence the PendingIntents used to attach functionality to the buttons is lost.
More precise: no onReceive and thus no onUpdate is called when the android.process.acore Home process is restarted. In turn, no Intent is attached..Anyone experienced the same problem and knows how to circumvent this problem?
I have a requirement to implement an Exit button in my Android application. I don't really care about killing the activity stack, I just want to have the same effect as pressing the Home button. So that application state is saved and can be returned to. But this doesn't accomplish anything, the PhoneWindowManager does not get the key press.I assume I need to launch an Intent with the right info, but I haven't been able to figure out how that would be done.

View 1 Replies View RelatedI need my activity to handle HOME button press with a receiver programmatically, but the event is not firing. I can,however, successfully register and capture this intent filter if I declare it in a manifest.xml activity section.Does anyone know why this doesn't capture the home button click?By the way, I tried working around this by creating another activity and specifying its intent filter in the manifest. I set the activity enabled="false" in the manifest but I couldn't figure out how to enable that activity at run time. Bottom line, I only want to register the home button intent filter for my application only when my application is running, and I can't figure out how to do that.
View 2 Replies View RelatedI have some questions related to Android's home-screen contents:
1) Is there a way to programmatically delete a home-screen shortcut on Android? I know that it can be done manually but I want to do it in code.
2) Is there a directory where all the contents of the home-screen are stored and, if there is, is there a way to update the contents of this directory?
I am trying to capture my activity to handle HOME button press with a receiver programmatically, but the event is not firing. I can, however, successfully register and capture this intent filter if I declare it in a manifest.xml activity section.
Here's the code for the receiver:

I put a breakpoint here to see if this gets called } };
I've a widget which i would like to delete programmatically if the user gives the command by clicking on some button or so.. But as per my knowledge the app programme and the widget programme will be running in different processes. So how is it possible to get the controll of another process remote view and delete the same clearing all the db contents related to the widget?

This works on intents and broadcasts and is pretty straight forward stuff with putextras using the reminder id from the db. My problem is, if some one restart the phone, i guess all the scheduled alarm and vibrator tasks for the reminder will be killed. Once the phone restart again how to recreate the scheduler tasks.

View 2 Replies View RelatedI'm building a game which works as some type of a quiz. I ask user the question and when he submits the answer(click or touch correct answer) I need to refresh the page with some other question.
How should i implement this? How to wait for users answer and continue when onClick or OnTouch listener finishes?
Should i use Handler class, intents or something else?
I want next scenario:
On the screen I have a question and 3-4 clickable ImageButtons. I'm building some of the layout dinamically from custom showQA() function. User choose the answer and if he clicked the correct answer i should start some type of animation on the screen. I've done that from the onClickListener. Now, i need to build layout again(show new question and answers) from the showQA() function which must be called after that animation showed to the user. How can i know when the onClickListener() finished its work?

Also, is there a way the video can be resumed from where it left off?
I am testing an android device with eclair using the 2.1 CTS version. When CTS completes a set of tests and restarts the device a "device disconnected" messages appears on the CTS console. However after the device completes the restart to the android home screen CTS does not detect that the device is back online. I have to physically disconnect the USB cable and re-connect it. Do you think this is a device side issue or a USB driver issue on the Ubuntu machine (intrepid) where I am running the CTS?

View 3 Replies View RelatedIn my android app i have an ui-update-thread that keeps all my views up-to-date.
Code...
within onStop() to prevent the thread from running all the time. if i don't do this, it would keep running even if i close the app!
problem is: how do i bring this thread back to life when returning from some other activity to this one? run() doesn't work, calling the initial start() in some other method like onResume() crashes the app.
I've searched and I know it seems some people frown upon using activities within tabs, but moving past that...how would I restart a tabbed activity while still keeping the tabs visible? I have an activity in a tab, I use the menu to create a new activity to update the tab's activity displayed info, when I return from the menu activity I want the new information to be displayed in the tab's activity. I am using startActivityForResult() from the menu choice, but when I return and try to restart the activity...it wipes out the tabs above(I guess as expected, but I want to re-launch the refreshed activity within the tab).
Creating the tabs:
TabHost host = getTabHost();
Intent home_intent = new Intent(constants.HOME_ACTION,
null, this, homeTab.class);
Intent inbox_intent = new Intent(constants.INBOX_ACTION,
null, this, inboxTab.class);
Intent stats_intent = new Intent(constants.STATS_ACTION, null,
this, infoTab.class);
host.addTab(host.newTabSpec(constants.HOME_TAG)
.setIndicator(getText(R.string.home_label),
getResources().getDrawable(R.drawable.icon))
.setContent(home_intent));
host.addTab(host.newTabSpec(constants.INBOX_TAG)
.setIndicator(getText(R.string.inbox_label),
getResources().getDrawable(R.drawable.icon))
.setContent(inbox_intent));
host.addTab(host.newTabSpec(constants.STATS_TAG)
.setIndicator(getText(R.string.stats_label),
getResources().getDrawable(R.drawable.icon)).setContent(
stats_intent));
Return from the menu activity in the tab's activity(updating database info): code...
Activity SplashScreen is the launching activity for my app. It sends a request to my server and gets back a user data it then uses to populate a user object which is a static object. Once it has that it calls the MyMapView activity and finishes itself. A force close occurs when I hit the home button and then open up enough other apps so that Android kills MyMapView to get more resources. Now when I open my app again it tries to start MyMapView and bypasses SplashScreen. There is no user object so I get null pointer exceptions. I have tried to Override the onSaveInstanceState and OnRestoreInstanceState but it seems that those are not available when Android kills the activity. I also tried android:finishOnTaskLaunch with the SplashScreen (maybe this should be put on MyMapView but the article I read said different) and that seems to have no effect. What I would like is for the activity to not restart after Android has killed it. What can I do about this?

I'm writing a Tetris application on Android for my bachelor thesis at the University of Hasselt. Currently I have a working Tetris base game, but it just keeps on ticking when the activity gets in the background. I'm trying to fix this by overwriting the onStop()and onRestart()methods.when I press my home button on my device I will go to my home screen and onStop() is called. Because the gamemode is now "PAUSE", the game wil not tick anymore. But now, when I longpress my home button and select my tetris activity again, the activity pops up, but it isn't ticking! This is because the onRestart() is never called when I return to play my application.What is the reason that this method is never called? Am I understanding the activity lifecycle wrong?
