I want to show a simple toast, when exiting an application. The problem is, that the toast is not shown. I assume it is because the acitivity is finished or because of System.exit(0), but I don't know how to solve it. Does anyone have a tip?
In my activity I have the following code...

How can i make an activity go to background without calling its finish() method and return to the Parent activity that started this .I tried so much but it really dint help.So if you guys could help i would be very thankful.

When you click on the different tabs, no matter how many times you navigate between them, when you press the back key you leave the entire tab group, instead of navigating to a previous tab. My problem is, I am not using an actual TabActivity.
Does anyone know how to specify to Android that I'd like to mimic that behavior with a group of activities? The classic solution (that I know of) would to simply finish() the activity as you navigate away from it. That clears the stack, so that when you went from A1 and then to A2, and pressed back, you don't go back to A1.
The problem with using finish() is that I don't want the activity removed from memory. These activities load data from the network, so unless the data was cached, it would need to be reloaded on every navigation which would not be a great user experience.
I was looking at the flags which you can specify how to change this behavior: http://developer.android.com/guide/topics/fundamentals.html#acttask I tried using these: intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); But no matter what, when I go from A1 to A2 and press back, I always get back to A1.
In trying to clear the navigation stack without using finish()?
Hopefully the title wasn't to confusing but what I meant was the following:
Lets say activity A starts activity B by calling:
Intent myIntent = new Intent(Activity_A.this, Activity_B.class);
Activity_A.this.startActivity(myIntent);
Could I save/free up some memory by finishing Activity_A after Activity_B is begun (if thats even possible). Maybe through the following:
Intent myIntent = new Intent(Activity_A.this, Activity_B.class);
Activity_A.this.startActivity(myIntent);
Activity_A.finish();
Or would Acitivty_A call startActivity() and wait for Activity_B to finish before it called finish()?
The idea would then be that when the users end with Activity_B, it would just restart Acitivity_A (and finish itself in a similar fashion)? Would this create too much overhead? Thanks for any answers and I apologize if the formatting of this post isn't correct.
If I am running a service, and I want to sent a toast, the phone lights up. Is there a way to show the Toast without turning on the light?

View 2 Replies View RelatedI am working on learning Android programming. I am attempting to build an app that shows a list of items, and when the user clicks on an item, it will display an image of that item, as well as information about it. I'm not sure the best way to present this information. Would using the Toast widget be best? Or TextView? Or, is there another way, like creating a new activity, that makes more sense?
After the user clicks on the list item, and reads the presented info, they should be able to return to the list.
I noticed that a toast isn't displayed when it's used inside a catch block.
Does anyone know how to show toasts when catching exceptions?
I have a Activity called main. If I call Toast.makeText(this, "Hello World from main", Toast.LENGTH_SHORT); this works fine. However, for every other activity in my application, I cannot display a Toast. No exception, nothing in the Log but I don't see the Toast. Code...
View 1 Replies View RelatedI am currently working on my first app which grabs a ZIP from the internet and the extracts it to a certain location. Everything works great but I can not figure out how to show a Toast message when the extraction operation is done.
The code I am using for unzipping is:
Code:
package mmarin.test.download;
import android.util.Log;
import java.io.File;
[Code]....
As I said above, only issue is displaying a message that everything is done.
When using setDuration for a Toast is it possible to set a custom length or at least something longer than Toast.LENGTH_LONG?

View 4 Replies View RelatedI am trying to write an application that will dynamically load data to map while user pans or zooms it.
So I need to track when map finished to change its view state (stops panning or zooming) and then load a new portion of data for creating markers. But in fact Google Maps API doesn't have any events to handle this.
There are some methods like creating empty overlay to control onTouch events and so on, but map panning could last long after user finished his touch (cause GMaps use some kind of inertion to make pan smoother).
I've tried to subclass MapView but its draw() method is final thus cannot be overriden.
Any ideas how to make precise handling of pan and zoom finishing?

View 2 Replies View RelatedI try to show a ProgressDialog at the beginning of my application from an Activity. I debug the application and in theory the dialog is created because it prints a line from onCreateDialog... method.
For more test, I try to show a toast with:

And nothing is showed.
If is useful, the application is a widget.
I want to show many listviews in one activity. Something like

Every listview has different type of adapter. For this, I made the activity class like:-

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.
Here are the classes:

The second class that should show when the button is clicked, but never does:

How do I create a button that will show the second activity?

View 1 Replies View RelatedI'm writing an android application which listens the phone calling events. What I want to do is, if there is a call incomes or outgoes, an activity shows with my customized info.I want to this screen keeps showing during the calling period. However, if a call is coming, the system UI which shows the contact always appears on top of my activity.I've found some apps already realized this function, but mine can't.
View 1 Replies View RelatedI'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.

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.
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.
