I'm releasing my first app soon, and this is the first time I'm doing any of this on my own. Looking into the future of it, there are features I plan to implement within the coming months. But looking at me adding features, I realize I would be altering the original source, so if someone finds a bug, I need to either wait, or completely undo everything to fix it. What are some options for managing my source code and stuff?

I've been working at adding music, and installed iSync to pull playlists and tracks from iTunes (other computer software is not an option as the wife LOVES iTunes and her iPod.)Than being said, the iSync program is easy-to-use and nice, but I'm finding that the EVO's music app is taking its own sweet time to recognize the tracks from the SD card.I can wait, but my fear is that it will need to do this each time I launch the app? Is this the case, or is it a one-time thing?Any suggestions on other ways to manage music and playlists on the EVO?

Deleting the file doesn't clear the error, and Eclipse won't compile the project. It just reports that your project contains errors. The solution is to go to Project/Clean. This will clear the error in the project and allow it to compile.

But there's still an issue: I are trying to have an Android class call a non Android Hello World class. I tried compiling our non-Android Hello World class in a separate Eclipse workspace. I then packaged it into a jar. I imported that jar into our Android Hello World class.
I then called one of the methods in the non-Android Hello World class. When I ran the Android Hello World class as an Android application, the following runtime error occurred. Here are the Android debug logs:

I have 2 android projects out of which I modified one to work as a library. I want the main project to refer to this library to perform few functions. While this scenario works just as expected, I want to introduce one more functionality. I want to link this library project with another just a java project which has code common to both Android and Blackberry applications. This second part however doesn't seem to work and throws "The application <appname> (<package name>) has stopped unexpectedly. Please try again" with a ForceClose button. I would greatly appreciate if someone can give a brief information on how to make this work.
View 2 Replies View RelatedI am a C# developer and getting started with Android. I am attempting to duplicate a couple applications I already have in VS. The project is made of 2 executables and 1 common assembly. The 2 executables contain the application specific logic while the common contains centralized forms and logic (such as login form). I am using Eclipse. So how can I accomplish this layout?
View 1 Replies View RelatedI followed the instructions here on how to create an Android library project, and use it in an Android application:
http://developer.android.com/guide/developing/eclipse-adt.html
But it is not working. I can see the library project is added to my application but I cannot reference anything in it because it won't build. The R.java file from the lib is NOT being added to my application project, so the lib project contains tons of errors, everywhere it tries to reference it's own R.java file.
I don't know if this has anything to do with it, but in the console there are messages stating that the there is "No resource identifier found for attribute 'X' in package 'Lib Package'. My library package has a a few styleable attributes defined for a custom view I made, all of which are being complained about in this console message. The library builds just fine, and I don't get those messages in the console until I hook the library to my application, so I don't know what's up with this.

Very different launcher in a lot of ways.
Has left to right scrolling in the app drawer instead of vertical.
Has 2 main dock spaces for icons but if you swipe up on the app drawer instead of pressing it you will see what he calls the dock bar which has space for 6 more dock spots.
Tons of customization options.
When I right click the project in the eclipse, select "Properties". In the property page, select Android. According to the document, you can add the library project through that page. But my problem is that, there is no library information on the page. It only lists "project build target"

View 4 Replies View RelatedI'm looking for ways to back up the database of my app on an Android phone. I know that SQLite databases are just files, so I'd expect to be able to just copy the file to SD-card if one is available.However, I'm unsure as to how I'd prepare my database/activity for backup/restore.
When starting, my main activity reads the entries from one table in the database and displays them in a ListView. As shown in the API's "Notes" sample, I have a cursor that is automatically notified about changes to that table (ListView is automatically updated when I add/remove/update records in the table).When I copy the database file to SD-card, I should not have a problem. But what if the user wants to restore a database file? I can't just copy the file back to the data folder, can I (EDIT: ... while a view displays data from the database and thus maybe holds an open connection)?
What would be "best practice" when implementing backup/restore? One approach I've considered is:Open a special "restore" activity that holds no open database connections
Call finish() for the main activity to remove it and close database connections Copy back the database file Open a new "instance" of the main activity all finish() for the "restore" activity,....Would that be the way to go? Thanks for any advice!

Horizontal label turned 90 degrees counterclockwise (letters on the side)

View 1 Replies View RelatedMy application has an IntentService which runs periodically to download data from a remote server. The download task is run inside an AsyncTask which has reference to Application context only.
The data downloaded is for entire application and is displayed across four different activities. When the download completes(AsyncTask completes) the service is notified of the same. Now, the service needs to notify appropriate activity to update its view. The service is not aware of which Activity of what application is in foreground.
How do I make that connection? How does the service pass a message to the activity in foreground that new data is available and it should update its views?
I have a free app that has 64% of ratings at 5 starts, but still has 9% of ratings at only 1 start, some of them even said that my app is an "useless garbage", so I think maybe I need to leave a reply to those users to explain something or answer their questions.

I have an application I am currently working on for a client which is suffering from a particularly hard to debug problem. Every so often, the device screen will go blank, not just while running my application, but entirely. If I press the home button, for instance, it's still blank. This happens fairly rarely ( I myself have only seen it once or twice in a couple of months, and unfortunately couldn't gather log information immediately when it happened. What log info I was able to gather seemed to show that the phone continued to run properly - I was still seeing events in the log file - the screen was just blank ). So far, this has only been observed while running on Motorola Milestones ( this may or may not be coincidence - it's hard to tell given the infrequency of occurance ). Has anyone else observed anything similar? Any suggestions as to possible causes/ways of debugging?
