Are there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.
I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.
What advantages of multiple activities am I missing?
I'm working on an application using xml layouts.
I wish to know which is better:
1. Use few activities and change its contentview
2. Use an activity for each 'view' needed
If both works, in which case which option would be better?
I'm planning to develop and app that presents the users with several different screens (of different information).
Was wondering what would be the best way to implement this?
Is it better to have separate XML layouts and an activity to display and allow the user to interact with each screen of data?
OR would handling all of these in the same activity be more efficient (and dynamically load / unload each layout)?
I can capture an audio stream from the mic, but can I capture the currently playing audio stream?

I want to setup an app or if possible in another way, to play a certain song when booting the tablet. Or even after it has booted. I just want it to start playing a song all of a sudden If this is possible , I might want to start working on it asap, since I will give the gift on Thursday.
I've had Handcent sms app for a long time and never had any problems, I love it. But with the newest update it has begun playing a long annoying song when I get an sms, even though I've set it to a normal single sound. I've tried reinstalling it, but it doesn't help. Can anyone help me? Or recommend another sms program, just as good.

After this happened I uninstalled mixzing but that didnt help. I can change the notification sound in handcent but that dont work. Any idea why handcent is firing up my music player or folder? Im back to using the stock player but it still happens.

View 4 Replies View RelatedWe're developing an Android game and we play some background music for our intro (we have an Intro Activity) but we want it to continue playing to the next Activity, and perhaps be able to stop or play the music again from anywhere within the application. What we're doing at the moment is play the bgm using MediaPlayer at our Intro Activity. However, we stop the music as soon as the user leaves that Activity. Do we have to use something like Services for this? Or is MediaPlayer/SoundPool enough? If anyone knows the answer, we'd gladly appreciate your sharing it with us.

View 3 Replies View RelatedMy situation is the following: I have written one MapActivity class that is able to display a set of places as well as single places. On startup, the application creates an instance of this MapActivity and displays multiple places. If the user clicks on a certain place, then a new Activity is launched that shows the details of the selected place. This activity has a menu item that allows the user to view the place on a map - this causes that a new instance of the MapActivity is created, except that now only this single place is displayed.
The problem now is that if the user navigates back to the first MapActivity (the one that shows multiple places) the tiles won't be loaded anymore + sometimes OutOfMemoryErrors are encountered. According to the Android JavaDocs, it is only possible to have one MapActivity per process. However, I don't want to define my MapActivity as a singleInstance/singleTask, since the user should always be able to navigate back to the first MapActivity that shows multiple places. I have seen that the Google Places app (which has come with Google Map 4.4) for Android uses multiple MapActivity instances. How is this possible?
I'm having a problem when I create a Sub-Activity to my main activity. Both activities have their own GLSurfaceViews. Nothing on Logcat. Basically It just opens up the new view and it's black and it never renders with the new opengl stuff. I've tried a bunch of stuff, just want to know if there's some special way I need to pause the first opengl activity to get the second to run, or if there's some toggle which I am missing, or if it just can't be done. When I open the second activity with a GLSurface View, the first activity stops drawing frames, but the second one, never initializes or starts to draw.

i have an android app with several activities. I need to start a timer when the first activity starts and end the timer when the last activity starts and show the elapsed time. How can i use Asynctask to do this.
View 2 Replies View RelatedI have developed a simple android application, which when started opens a Timer. User is given two buttons, start/ pause. This is working fine.What i want to do is to add a way to support multiple timers when a user swipes his finger on the screen.When he swipes from left to right, a new timer should show up, but the previous timer should not stop. This is a way to add multiple timers.Also, when he swipes from right to left, i want a previous timer to show.This is what i have done so for. I have a timer activity. I have added a touch event on it. When, a person swipes his finger, i get the co-ordinates and decide whether its from left to right or right to left.This functionality is working fine, as i can see the appropriate log messages.The problem is when I'm trying to load Timer Activity.It just loads the previous Activity and doesn't really create a new one (I figured this from the timer).Is there any way to do it?
View 1 Replies View RelatedI need to be able to use one object in multiple activities within my app, and it needs to be the SAME object. What is the best way to do this?
I have tried making the object "public static" so it can be accessed by other activities but for some reason this just isn't cutting it. Are there any other ways of doing this?
I have tried to make a series of dialogs, like a questionnaire, that the user needs to answers a series of questions selecting one or more checkboxes. I can do one, just fine, but when I try to make more than one question (lets say 10), it does not show, or show all the dialogs. I tried using dialogs or new acitivities.
So, my problem is I have multiple questions, one to be presented each time, and I need to wait for one to be responded so I can ask the next one. How do I accomplish this?
My first attempt was with a dialog box... but obviously it got all the boxes stacked in each other:
CODE:.................
I have a service component (common task for all my apps), which can be invoked by any of the apps. I am trying to access the service object from the all activities, I noticed that the one which created the service [startService(intent)] has the right informaion. But rest does not get the informaion needed.
My Code is as below:
CODE:................
If I invoke startService(intent). it creates a new service and runs in parallel to the other service.
If I don't invoke startService(intent), serviceObj.getData() retuns null value.
I'm trying to refactor/redesign an Android app. Currently, I've one UI activity (Activity 1) that creates a DataThread. This thread is responsible for network I/O and interacts (provides data) with the UI activity via a handler.
Now, I want to add another activity (a new UI screen with Video) - Activity 2. Activity 1 is still the main activity. Activity 2 will be invoked when the user clicks a button on Activity 1. Activity 2's data also comes from the DataThread.
My idea is to put the logic of my DataThread inside an Android Service (DataService). My question is - can more than on activity bind to my DataService at the same time? Is there a way to tell the service to provide data to a specific activity only?
Were looking into Android for writing a tablet based system. Part of the design is for the system to be as modular as possible. One aspect of this is to display any "STATUS" activities in a side view on the screen. It looks like I can use PackageManager queryIntentActivities() to find the activities that show status information. But, can I display these in a single view all at the same time (via a linear layout)? The activities would be installed in separate apk's (features). Can this be accomplished using ActivityGroup? Is this even allowed in Android? Everything I've read implies that Activities take the whole screen or float on top. This implies only one activity can be active at a time where as the design I'm thinking of uses the activities more like widgets.
View 1 Replies View Relatedis it possible to show two activies on same screen at a time.and each activity is showing data which changes with time.
View 1 Replies View RelatedWe are building a complex Android application consisting of many screens and workflows spread across many Activities. Our workflows are similar to what you might see on a Bank's ATM machine, for example, there is an Activity to login in that transitions to a main menu Activity which can transition to other activities based on the user's choices. Since we have so many workflows we need to create automated tests that span multiple activities so we can test a workflow from end to end. For example, using the ATM example, we would want to enter a valid PIN, verify that sends us to the main menu, choose withdraw cash, verify that we are on the withdraw cash screen, etc., etc., and eventually find ourselves back on the main menu or "logged" out. We've toyed with the test APIs that come with Android (e.g. ActivityInstrumentationTestCase2) and also with Positron, but neither seem capable of testing beyond the bounds of a single Activity, and while we can find some utility in these tools for some unit testing, they won't meet our needs for testing scenarios that cut across multiple Activities. We are open to an xUnit framework, scripting, GUI recorders/playbacks, etc. and would appreciate any advice.
