Android : Beginning Programmer Interested In Phone - Should I Start With Java?
Apr 21, 2010
I'm a beginner in programming. My experience so far is only in Actionscript 2 and 3. So I have a basic understanding of declaring variables, loops, arrays, if/then, do/while... I'm wanting to move to developing for Android phones so I'm wondering what suggestions people have for where to go next. Should I jump right to Android? Start with a 'beginning Java' approach? Or should I go some other route to beef up my knowledge of OOP concepts before launching into Android? I have my Dev environment set up and completed the Hello Android tutorial and I'm just wondering if I am going to be in over my head quickly?

I have a native application that I would like to start from a Java interface. Does anyone know of a good way of doing this? can start the application using adb, with no problems. I can also start the application using Runtime.exec(), but that doesn't work so well for me; I need the application to run outside of a Java Runtime Process. Any ideas?

I wrote an android app and so far it works perfect except for on one phone. It is the exact phone that I have with 2.2 on both phones and mine works perfect. The other phone is getting force close all the time but only when opening an activity that queries my image DB and tries to show a gallery. Every activity crashes in the same place, the viewimages. At first I thought it was the intent that was doing it but one of the activitys does not have the intent, it opens the images below the gallery. This works on the emulator, on my moto droid and on a few other different droids. Here is the code for the gallery and my bitmap decoder.
The error is below that.
CODE:..............
Here is the error

I am making an app for Android, in my Activity I need to load an array of about 10000 strings. Loading it from database was slow, so I decided to put it directly into one .java file (as a private field). I have about 20 of these classes containing string arrays and my question is, are all the classes loaded into memory after my application is started? If so the Activity in which I need these strings would be loaded quickly, but the application as a whole would have a slow start...
Is there other way, how to very quickly load an 10000 string array from a file?
UPDATE:
Why I need these strings? My Android app allows you to find "journeys" in Prague's public transit - you choose departure stop, arrival stop and it finds your journey (have a look here). My app has a suggestions feature - you enter leter "c" as your departure stop and a suggestions ListView appears with stops starting with "c". For these suggestions I need the strings. Fetching the suggestions from database is slow (about 400ms on G1).

I know about camel case rules, but I'm confused with this m rule. What does it stand for? I'm a php developer, "we" use first letters of variables as indication of type, like 'b' for boolean, 'i' for integer and so on.
Is 'm' a java thing? Does it stand for mobile? mixed?

create or has in the past created an app for android. I have a very good idea, that ide like to put to work, and cannot do it because I dont know how. Also dont know if this is the right section really. If this works, or can work, it might revolutionize, lets say, Blackberry to Android and vice versa, messaging.

I have one year of experience in programming. After getting laid off in cuts I managed to get a job in telecommunications planning. I'm good at my new job and don't want to leave it but I miss programming. I'd like to be able to code in my free time (which is about 4 hours every evening 7 days a week.)
I can code pretty well in C#, reasonably well in SQL and poorly in a unix shell.
What sort of job should I get on the side? Would anyone hire me as a free lancer? Should I focus on making apps for phones (android) instead?

Is there a way of telling the phone with apps (not necessary for the proper functioning of the phone) start at start-up and which don't? I hate for unnecessary apps to auto start.

My music just started skipping, or hanging up, especially at the beginning of a track.
I think it might have something to do with scrobbleing. I just signed up for Last.fm, and discovered that I could scrobble the tracks I play from my other music players, which I think is a pretty great feature.
I have several music players: Tunewiki, MixZing, 3, and Zimly. (I'm trying to figure out which one I like best to stick with.) I downloaded ScrobbleDroid for the players that don't support scrobbleing natively.
Now, I don't know if the scrobble feature has anything to do with my music hang ups, but this is the only thing I've changed relating to music.

Happy Fourth of July weekend to all the US folks here. Now, before I go on I just want to say I am not sue happy nor am I looking to make a bunch of lawyers a bunch of money.I am wondering if anyone has heard of any class action by Android users against Apple for its Programmer exclusivity policy. I am referring to the agreement that requires programmers only to write an app for Apple using Apple tools. I am not an apple hater. The reason I ask is that I have noticed there are quite a few event specific apps that are only available to the iPhone that just dropped (don't judge but the one I really wanted was the official Tour de France app as it started today)I feel that is safe to assume that the Official Android app is not yet available because of the aforementioned agreement that I believe most on here are aware of.ie: hurdles of not being allowed to cross platform develop forces developer to choose one store over the other. I know the FTC has started some investigating of Apple's policy for anti trust violations. I am just wondering if Android users as a consumer group can be proactive through litigation (sounds like such a dirty word *sigh*) to help end that policy.
I do not need my nice Evo 4g to be an iPhone. I like no dropped calls the ability to customize my pocket computer/phone as I see fit, but I am bothered knowing that when a new app is released that I want there is no way to get it because the developer has been FORCED to agree not to make it. (By only being allowed to use Apple supplied programmer tools).I understand the developer can make the app for Android using other tools, but for time sensitive events like sporting events most will not have the time or willingness to put out the capital to make both. Please do not turn this into another Apple sucks thread. I am just interested in exploring the legal option of Android users arguing they are negatively impacted by Apple's exclusivity policy.

Does anyone else have problems with the screen scrolling without being touched? My eris will scroll all the way to the left and will stay there for a few seconds. The most annoying thing is when I am texting it will scroll to the beginning of the message and then freeze and will continue to force close until I turn the phone off then back on then it does the same thing. This is the 2nd Eris I have had and if I cant upgrade soon then Im down-grading back to my LG.

I was wondering if anyone knows how to sort pictures so that the newer pictures are at the beginning of the list? The default is that new pictures are all the way at the bottom, and since I have over a hundred pictures its annoying to scroll all the way to the bottom. I don't see any option to sort the pictures in any other way.
