Android :: Best Way To Handle Preserving Data From Spinners

Jun 14, 2009

This is a general architectural question. I want to offer a user a simple two page form. The first page will have a few Spinners for the user to select options from. The second page will have a series of EditTexts for the user to fill in. After the second page, the user clicks a button to generate a text file based on the values they have input. My question is: What is the best way to handle preserving the data from the spinners on the first page of the form, in order to place them into the text file? I feel like the "architecture" should be something like this: 1. User selects Spinner values on first page and clicks button to move to next page of form.. 2. Spinner values are placed in database 3. User fills in EditTexts on second page. Clicks button to generate text file. 4. Database is queried for Spinner values, which are added to newly created text file, then EditText values are added Does this strategy make sense? Does anyone have advice on a better way of handling the gathering of two pages of form input then using it to create a text file? The user would need to be able to flip back and forth between the form pages as needed.

Android :: How To Handle Application Upgrades From Free To Paid Version / While Preserving Any Data

Jun 10, 2010

I want to have a free version and a premium version of the same application. When people buy the application, I want them to be able to "upgrade" without losing their data, i.e. the premium version should install over the free version.I want to use the same code base and just switch a setting to build the premium version.
Andoid Market does not let me convert a free app to a paid app, so the trivial option is not available.I am curious if someone has tried this successfully. How does Android Market identify an application - will it think that the premium version is a different app and just install it in parallel?

HTC Desire : Preserving Battery Life / Should Background Data Be Switched Off

Jun 26, 2010

It seems that one of the biggest drains on the battery is apps synchronizing constantly but I'm still confused as to how to set the phone up with this in mind! Should Background data be switched off?! What's the difference between Background data and Auto-sync in settings? Which should be on, or should both be off?

I guess what I'm ideally looking for is one button I can press on my Homescreen which will sync everything when I want it to, say a couple of times a day. I'm thinking gmail, news and sports updates, weather, that sort of thing.

Or am I being too fussy? It seems a shame to have such a clever phone but have to have everything switched off because of the battery. I'm tempted to have everything switched on constantly and just charge it all night every night, have it on charge at work and carry a charger in the car just in case. Does anyone else do this?

If people more knowledgeable than me about this (not difficult ) could post how they have their phones set up this would be extremely useful to me and I'm sure lots of other peeps!

I'm in danger of becoming obsessed with this - phone has only been on for 2 hours after an all night charge, I've done practically nothing with it and the battery indicator in the notification bar has already run down slightly!

Android : Can Droid Handle Data?

Jun 8, 2010

I have just gotten my first Android based device, the HTC Droid Incredible.

I am not new to the world of smartphones (I have owned a Blackberry and have worked on many other Blackberries), but I am new to the whole world of Android.

I really do like it so far, but I have a question...

How does Android handle data? What I mean by this question is this: Does Android use a store and forward approach to sending data (emails)? Or does it send it out and if it doesn't have a good connection, it will just fail out, never to try again?

And based on the fact that it uses data, I also assume that it will never lose it's data connection even though a cell phone tower might be buried under voice calls?

The reason I ask this is because during 9/11, many people's cell phones could not make or receive calls but those who had some of the first Blackberries were able to send and receive emails just fine due to the store and forward approach.

Also, another reason is that this device will be used in a SHTF type of situation due to it's capabilities and I want to make sure that it will work with data (sending emails), although I may not be able to make voice calls with it.

I will be making a mobile application in Android. My application is like Google Map's Get Direction feature, but a lot more complex, so I need to store data about points in the map.

Android : Way To Handle Camera Preview Data Without A SurfaceView?

Mar 25, 2009

I want to receive the data from the preview of the Camera, but without having to set a SurfaceView with a SurfaceHolder in the view of my application. I want to do something like this: Camera cam =; cam.setPreviewCallback(new MyPreviewCallback()); cam.startPreview(); This will not work because I need to call setPreviewDisplay (SurfaceHoler) before I start the preview. I can get a SurfaceHolder from a SurfaceView, but I don't want a SurfaceView, because I don't need one. I just want to handle the preview data by myself.

Can't Get Any Spinners To Compile?

Oct 27, 2011

I can't get any spinners to compile. What usually happens is the resource file disappears. I am using the tutorials from the Android site.

Everyone seems to say that resource files disappear when there is an xml error. Everything looks right according to the tutorial. The error is in the xml line android:text="@string/planet_prompt". I can't move on in my project without getting spinners to work.

Jun 12, 2010

I have an app which uses 3 different spinners to allow users to choose from some options.

Iīd like to know if thereīs a way (or a property) so I can force those spinners to show the options list using text in black.

Android :: Best Way To Store Application Data / When Data Stored / Data Format Could Change In Future Versions?

Mar 4, 2010

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

Android :: How Well Does G1 Handle Imap E-mail?

Nov 10, 2008

I briefly owned a blackberry not too long ago so that I could handle work e-mail on the go. However, I was disappointed with its e-mail capabilities (or lack thereof) and quickly got rid of it.Due to the nature of my work, I use several different e-mail accounts and I need to be able to access them using imap so that when I move or delete an e-mail locally, it gets updated on the server. Can the G1 accommodate this? For each e-mail account, can you specify things like imap and smtp server?I use a gmail account, a google apps account and three other accounts with other e-mail providers.
