Android :: Avoid Restarting Background Threads On Orientation Change
May 19, 2010I start a number of background threads in my Activity onCreate that do work to keep the UI free. I was originally destroying these threads in onDestroy. However, the idea of shutting down and restarting these background threads every time there is an orientation change seems like a waste of time to me. What is the preferred way of avoiding the shutdown of my background threads on an orientation change? I supposed I could set a flag in onSaveInstanceState and then not destroy my threads if this flag is set. Is this a valid approach or is there a more standard framework approach that I am overlooking?

View 4 Replies View RelatedAndroid :: Screen Flip Doesn't Trigger An Orientation Change And Activity Destruction/recreation
Aug 29, 2010I'm testing an app on a Droid. It's a kind of card matching game. I'd like to keep the cards physically located in the same place on the screen regardless of a screen rotation. For example, I can put my thumb on a card, rotate the phone any way I please and the card stays fixed under my thumb. However, the orientation of the content of the card will change to match the current phone rotation. I handle this by transforming the card grid in onCreate. This works fine for 90 degree rotations, but if I do a fast 180 degree flip from one landscape mode to another the screen simply flips and the Activity is NOT destroyed and recreated.
This seems contrary to the documentation:
http://developer.android.com/reference/android/R.attr.html#configChanges
"public static final int configChanges Since: API Level 1
Specify one or more configuration changes that the activity will handle itself. If not specified, the activity will be restarted if any of these configuration changes happen in the system. Otherwise, the activity will remain running and its Activity.onConfigurationChanged method called with the new configuration. "
I am NOT specifying any configChanges in my AndroidManifest.xml file, so it seems that the activity SHOULD be destroyed and recreated. Why isn't it? Is there some way I specify that it should be destroy/ recreated?

Mar 12, 2010I have a TabActivity. Each tab points to a sub activity. Works great.
Is there any clever way to refresh one of the activity tabs? I just want to 'restart' the activity in tab #3 for example. Not sure of a good way to do this other than building in refresh support to the activity itself, or clearing ALL the tabs and recreating all of them.
Android :: Avoid History Of Activity?
Oct 13, 2010I have total 3 activities.
First activity(A) starts second activity(B). From Activity B, 3rd activity(C) is called.
Activity B, shows list with checkbox to select items and single OK button. On clicking OK button Activity C is called with selection.
When user clicks BACK button in Activity C, by default Activity B is displayed (with selected checkbox).
I want to display Activity A when BACK button is clicked in Activity C.
How to achieve that?
I have handled OnKeyDown() in Activity C to startactivity(A). it is working. But when user clicks BACK button on Activity A, again Activity C is displayed. while application should end.
In this direction how to skip Activity B is ever called?
Android :: Refresh RelativeLayout When Orientation Changes Without Restarting The Activity?

Android :: Avoid Non Static Inner Classes In Activity?
Jun 17, 2010Since I seem to have caught two activity references in a heapdump, where the Activity is set to singleTask. Romain's advice on avoiding memory leaks includes: "Avoid non-static inner classes in an activity if you don't control their life cycle, use a static inner class and make a weak reference to the activity inside"
What does this mean exactly? I can't find any examples, positive, or negative for this rule. I do have some non static inner classes in my activity. Most of them are anonymous inner classes like this one. I see hundreds of them in the samples:....................

Android :: "Keyboard Not Responding" In Emulator / How To Avoid It
Jan 19, 2010I'm using Android 2.1 SDK on MacOS 10.6.2.
When I try to run the standard Notepad app in the emulator, I get the expected messages from Eclipse. code..
deprecated. Apps should cease use of QuickDraw and move to Quartz.code...
Then it starts to go wrong. A dialog flashes on to the screen too fast for me to read it.
Then notepad starts (I have to "unlock" the screen manually by dragging the lock tag)
Then there is a "Force close or wait" dialog that announces "Application Android keyboard (in process com.android.inputmethod.latin) is not responding."
The app won't do anything further at this point. I have not made any changes to the app.
Has anyone else seen this error?
Does anyone have advice on how to avoid it?
Android :: Orientation Change Crash In Tab Activity With List Activity
Jan 21, 2010When views with different type have same id and screen orientation changes,
either java.lang.ClassCastException: android.view.AbsSavedState$1 or java.lang.IllegalArgumentException: Wrong state class -- expecting View State will occur. (depends on the view's order)
Because View.dispatchRestoreInstanceState() checks id only.
You may wonder why anyone would make views with different type to have same id.
But it can happen when you use tab activity.
Imagine you have tab activity with two children activity.
Tab1 is ListActivity and Tab2 is ExpandableListActivity.
Both activity have id of "@android:id/list" but the type of view is different.
This means we cannot use ListActivity & ExpandableListActivit at the same in one tab activity.

View 10 Replies View RelatedAndroid :: Change Intent Bundle Data Before Activity Recreated After Orientation Change
Jul 30, 2009I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?
Android :: Soft Keyboard On Activity Startup
Jan 12, 2010I am struggling trying to have the soft keyboard appear in a search screen and from the looks of numerous pleas on various forums, I am not the only one. I have tried many variants, culling from the byzantine attempts of those others.
InputMethodManager imm = (InputMethodManager) getSystemService
(Context.INPUT_METHOD_SERVICE); imm.showSoftInput (query, 0);
(for 0, substitute InputMethodManager.SHOW_FORCED or InputMethodManager.SHOW_IMPLICIT.)
The problem seems to be that showSoftInput doesn't work from onCreate. This is a very common need. Surely there is a reasonable solution to this problem, or is it botched here?

Android :: Soft Keyboard Appears When Activity Starts
Aug 13, 2010I have an activity which loads a TableLayout. This is made up of TextView and EditView fields. When I run my app within the emulator the layout appears correctly (WITHOUT the soft keyboard appearing). When I run the app from a device (HTC Evo) and enter the activity the soft keyboard ALWAYS appears. I tried doing an OnFocusChange() for the first field in the layout and then doing:
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(tvIndications.getWindowToken(), 0);
It doesn't work. The soft keyboard always appears.
Android :: Show Soft Keyboard When Activity Starts
Mar 17, 2010I have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult() to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input. The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible" set in the manifest under the <activity> tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show.

Apr 26, 2010I have added android:windowSoftInputMode="stateAlwaysVisible" to my Activity in AndroidManifest.xml and here's my layout:
<?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">

<Button android:id="@+id/Button01" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Send"></Button>

When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts?

Android :: Disable Keypad Or Whole Keyboard Support On Activity?
Nov 2, 2010I have a layout with lots of different imagebuttons on it. Application is developed in full-touch, so there should be no response to keyboard or keypad on all activities except one, where user can input his name.
Is there a way to achieve that?
I've checked on debug, keypress and keypad press result in onKeyDown event. I've set it to return 'false' for all keys. But, for some reason, android keeps selecting my imagebuttons when keypad is pressed. And pressing Enter key result in View.onClick event.
How to totally disable all keyboard input for activity? I use Motorola Milestone for tests - a slider with a keyboard.
