I have a problem on going back (clicking the Back button) from sub-activity to main activity: from my main activity I launch a new one (with passing some extras). code...
In the started activity I am getting data from extras and showing, etc. So everything works very well until I click Back button to return back to main activity. Then main activity appears but directly after - grays-out. I can't do anything there anymore... This "grayed-out" style looks something like there should be a dialog displayed, but there is no dialog shown, just the whole activity is pushed down/disabled instead...
One another interesting thing I noticed - that activity is still alive in background, because if I click "Search" button the Quick Search Box appears on top of my activity and if I click Back button then (to cancel it) - it disappears and my activity then becomes fully functional again (gray-out effect simply disappears...)
Tried watching logcat, but it shows nothing useful, no exceptions thrown, just this text always comes up:
W/KeyCharacterMap( 564): No keyboard for id 0
W/KeyCharacterMap( 564): Using default keymap: /system/usr/keychars/qwerty.kcm.bin
What could cause this problem?

I have a link in my application that triggers a webview to open from webview.loadUrl. Sometimes it's takes quite a while to load the page, and in these cases I want to be able to use the built in back button on the phone to cancel the loading and go back to my application. How do I do this? Is there some way I can listen to the back button while loading the URL?

When you're in the browser long pressing on the back button takes you straight to the history page, very useful.

I have a TabActivity with several tabs. Each tab corresponds to a specific view, and those views may further switch to other views. For example, one of my tabs displays RSS feed list, after user clicks one of the RSS feed, it will switch to a view displaying a list of articles, and after user clicks one of the titles, a full article view will be displayed.I'm going to add support for "back" button in my application. For instance, in a full article view, after user presses the "back" button, it should switch back to the article list view. And if user presses it the "back" button again, my application should switch back to the feed list view.My idea is to maintain a Stack<View> during navigation, and every time user presses the "back" button, the program will pop a View out of the stack, and set it as the current view. But I would like to know how to set current view in TabHost.

I have the tronsmart CX-919 mini pc running 4.2 and there is an issue with the browser reverting back to the home page or the previous page. When I try to display a webpage on our intranet it reverts back to the homepage or previous page after about 3 hours. I need it to display constantly. I read somewhere that it was a Download Manager issue and disabling it would work but I can't find where to disable it. Also it was stated that Flash was an issue but i tried uninstalling it and it just reinstalled itself and the problem kept occurring. I just want to display a page in a browser and for it to stay on the screen (full screen) until I manually navigate away from it. I plan to leave it on for weeks at a time.

If you click on "Insert Coin" the game starts, and "touching" inside the map changes direction. Works on my PC and my n900...just trying to see if it works on Android. Not sure if its Java or HTML5 based.

This is my first android device and i'm loving it... but one thing that irks me is the use, or lack thereof, of the back button.
As I am navigating menus and options in the Settings, I cannot simply go back one menu using the back key. For example, if I go to Settings->Battery Manager->Battery Profile Options and want to go back to the Settings screen, I cannot.
Pushing the back button does nothing and I can only go back to the Settings menu by going Home, then re-entering.
Another quirk regarding the back button is when reading emails. Using a regular email account such as Hotmail, I cannot simply read an email and go back to the inbox using the button.
It makes navigating the phone very tedious.

if I set up a button in main.xml, I still need to actually create the button in my Activity, right? Like the XML just controls the look of the button, but you need to actually create a button by doing something like
private Button myButton; Just wanted to make sure I had this clear conceptually. You create an object in your class and then just tell Android to do something like myButton = (Button) findViewById(R.id.my_button);

Curious to know the reason behind not allowing updating UI elements from background thread in Android. Will main thread does something more (probably interacting with framework) after updating the UI elements so that changes can be seen on the screen? Is it the same case with other GUI tool kits?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
</LinearLayout>
Since the root element is a LinearLayout, which extends ViewGroup, why does main.xml get turned into a View instead of a ViewGroup? For example, in my main Activity class, I try to get the number of subviews that the LinearLayout contains like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ViewGroup vg = (ViewGroup) findViewById(R.layout.main);
Log.v("myTag", "num children: " + vg.getChildCount());
but it crashes when i call vg.getChildCount(). What is the right way of doing it?
