Is there any design guideline on the number of Activities an application could have? If there is a limit, what would be the ideal number of Activities that can be bundled in an Android application.

In my application, I currently have several activities that consist of a TextView and a scrollbar. The only difference between them is the string that the TextView displays. Is there a way to consolidate all of these into one single activity, and depending on how/where the activity is started from, changes the TextView? Perhaps send the name of the string as an argument to startActivity, or something along those lines?

Probably it is possible for Froyo at least. I found application called Easy Call Forwarding. But many people reckon it dosen't work actually. We can notice forwarded call by onCallForwardingIndicatorChanged() from PhoneStateListener but I have no idea how to set forwarding mode.

View 2 Replies View RelatedI've experienced two problems with Google Voice that are causing me to get charged minutes I wouldn't usually get charged. If I can't solve them, I'll have to go back to using my Verizon number. First, let me say that I'm using a new Google Voice number that isn't Verizon cell phone number or any other preexisting number. Second, my girlfriend is on my family plan, but she doesn't have GV yet. We're using the 700-minute plan, so we don't have a friends circle.
Problem 1: When I call my girlfriend's Verizon wireless phone using the GV on my Verizon phone, I get charged, and when she calls my GV number on my Verizon Wireless phone from her Verizon wireless phone, she gets charged. We don't cash in on our free in-network calling. I know, this should have been obvious, but it just never occurred to me until after I looked at the bill. I'd be able to work with that, though, and just select "Call without using Google Voice" or whatever when calling her if it weren't for the second problem. When people call my Google Voice number, I get charged when I don't answer. Usually, it's just a one-minute charge, but sometimes it's two or three minutes (don't know why). With anything less than an unlimited plan, minutes count. Not good.
Basically, i use my personal cell phone for work and personal use, i have multiple exchange accts that keep things sorted and seperated.
recently though i have been getting more and more business calls to my cell phone, during and outside of normal business hours.
what im looking for is an app that will take a selective group of contacts/phone numbers/CID strings and if it is a "business" call then forward it to a specific phone number (external number, the actual business line).
I have seen apps on the market and around that will forward calls to voicemail if they match certain filters, but i cant really seem to find an app that will forward to an external number. Any way I could accomplish this?
I'm selling my house, and my old phone number (which is still active), is on the advertisment signs and MLS. So, I'm going to keep paying my bill month to month for that account until I sell the house.
However, I'd rather not carry around 2 different phones. I did not port my number to my new service as my old number was not "local" to where I live now.
So, I have service with T-mobile and now Verizon with two different numbers. Can I set-up something where anyone who calls my T-mobile number, will ring through to my my Verizon phone/number?
I am trying to get the contacts from the phone but all I can get is the name, the phone numbers return null.

I have an Activity which is an OpenGL view. I also have an xml layout to use for preferences. Until now, to show the preference menu, I just brought it to front by setContentView(). And the same to get back to the OpenGL view. But is this a case where I should give the preference menu its own Activity? I guess this would make a few things much easier. For example, the back button would just work, opposed to now where I have to code it or it will just exits the application.And if this is a good idea, how do I pass data both ways? I have a class that store all preferences. Can I send it to the Activity and back again? Or is the best way to store the preferences in a sqlite database and then use it for passing data?

View 3 Replies View RelatedI have an application with three tabs. Through various interactions with the items in the tabs I end up launching other activities. The client has reviewed this and would like the activities launched "within" the tabs, so the tabs remain visible and if the user clicks the tab it goes back to the original activity defined in the setContent function. Is this possible and how would I go about this from other activities? (ie the child activities, not the one that defines the TabHost and has access to call setContent)?

View 1 Replies View RelatedI need to have two activities in an Android app that can be switched between each other with UI persistence.I would like the changes made in step 2 to be visible in step 4.I have tried using the singleInstance activity tag on Activity B to no avail. I would also prefer a more elegant solution than simply writing all object properties to a file or SQLite table.It seems that this behaviour must be easily achievable given that Android does it automatically for calls to onBackPressed() where the parent Activity's UI is saved.
View 2 Replies View RelatedI'm trying to create multiple tabs, each with a different Activity. The only downside is i'm using a custom layout file thus my class extends an Activity rather than a TabActivity. While trying to run, it fails and suggests calling TabHost.Setup(ActivityGroupManager agm)
View 3 Replies View RelatedI am working on an Android app that has multiple screens the user will need to navigate between and I am curious what the best practices are when switching between those screens. I am torn between creating a new Activity for each screen and simply changing the view (setContentView(R.layout.whatever)). The screens all share at least some variable values so I'm leaning toward changing views and using class level variables, but I'm worried a single activity could become very large and confusing with logic for multiple screens in a single file. I'd like to keep the code clean and separated, but I also don't want to be passing several variables around between views if that isn't needed.Being new to Android development, I'm hoping some more experienced members of the community could share their thoughts and let me know how best to handle it

Where shall I look?
