In my activity, I show a dialog under some condition like this:
CODE:.......................
My question is what do I need to do to ensure there is no resource leak? From the logcat, i see there is a case where it said a window is leaking or something like that.

I intended to show a dialog in a service process, then I tried to use the AlertDialog but got the below error message: WindowManager$BadTokenException: Unable to add window -- token null is not for an application The reason seems to be that the dialog is not used in a application context (activity should be fine?) Was there any way that can solve this problem?

I started two days ago with android, gone through the hello android stuff and also started to read the Hello Android book, which is great.
PROBLEM:
I use in my app - VERY EASY APP- the XML output. So basically the main activity just tells the android to show the XML layout of main.
But what if I have in the activity - code defined integer variable and I want this integer variable also be shown on the display?
How do I PUSH the integer variable to the XML??? From main XML reference to other strings in XML is easy - @string/app_name ... but how do I use the integer variable from the activity?
I have a service that downloads something from the Internet, it shows progress in notifications and in MyActivity (only when MyActivity is on foreground of course). How should the service post the progress to MyActivity? I know this could be done somehow with IBind but can I just simply do this in MyActivity:
MySevice.myActivity = this; startService(new Intent(....));
From MyService I can now call MyActivity's methods because I have a static reference to it in MySevice.myActivity, so I can call e.g. myActivity.sendProgress(63).
In my Android application, I have two activity classes. I have a button on the first one and I want to show the second when it is clicked, but I get an error.

In my activity I have the following code...
I'm experiencing kind of strange behavior of my application after hard Home button is pressed. When you press Home, everything is OK - my app goes to the background, showing Home screen. But if you try to choose my app in the main menu or in the list of last tasks it behaves like it was not started before and does not show the last activity you were on - it just starts from scratch, namely, shows the splash screen and starts next corresponding activities. Moreover, old activities of this app remain on the activities stack, and previous instance of the app is not terminated - so if you press Back for a few times you'll just run into those activities which were undoubtedly started during the previous session of work with my app. Splash screen activity is filtered by "android.intent.action.MAIN" filter and "android.intent.category.LAUNCHER" category. The strange thing is that all of that happens despite the fact that I do not intercept any Back key hits, or override any onPause or onResume methods. What's happening contradicts with my understanding of Android app lifecycle - I was sure that when you hit Home an app just goes to the background, and when you choose it in the menu later - it just unwinds and does not start anew. (Of course, unless stuff like that is stated in the app manifest or corresponding methods are overridden or something else). I also checked it for some other lifecycle events - such as changing orientation or flipping hard keyboard out - and none of those led to such strange results. It appears that the problem occurs when you try to start the app from main menu or menu of last applications.

Can we show the dialog when our application/activity startup?
View 4 Replies View RelatedI 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.
View 2 Replies View RelatedI 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">
<EditText android:id="@+id/EditText01" android:layout_width="wrap_content"
android:layout_height="wrap_content"></EditText>
<EditText android:id="@+id/EditText02" android:layout_width="wrap_content"
android:layout_height="wrap_content"></EditText>
<Button android:id="@+id/Button01" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Send"></Button>
</LinearLayout>
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?
Im trying to show a ProgressDialog while the activity is loading. my problem is that although i completed all the work in the activity. it takes a long time for the activity to load, i suspect this is because i use
multiple views with multiple listviews with custom array adapters inside a viewflipper. it takes a long time for the UI to show.how would i go about checking that all the UI inside the activity finished loading? or is there a way to preload all the activity and the UI?

I am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.

View 3 Replies View RelatedHow do I close a whole hierarchy of activities and show a new activity not present in the current task?
Context
Consider a FTP browser that resumes the previous session on launch. Each folder is displayed in its own activity. When I click on a folder, a new activity is started for the folder. If I press the back button, the app returns to the previous activity, which corresponds to the the parent folder.
I can logoff from the menu at any time. Logging off should bring me to the login activity (not present the current task when the app has resumed the session), and close all the other activities. How can I do this?
From what I've read, if the activity were in the current task I could use FLAG_ACTIVITY_CLEAR_TOP in the intent, but this is not my case.
