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?

I've been looking the source code available from the Restlet official tutorial.
I am trying to hit the Restlet server using the Android app from he tutorial adn I only get the JSON response, not the Java Object. I tried using all libraries and extensions, nothing works. When I hit the tutorial url though (http://restlet-example-serialization.appspot.com/contacts/123) I get the desired response. Any ideas? BTW, I am just using the server (GAE) in the example, not the GWT frontend.
Yesterday I looked at my phone and I noticed that for the mobile network data thing said G. Not Ev or Ev-Do or 1x or whatever else is the normal. I tried going online but it didn't work. Just restarted it and its back to normal, just wondering what was that.

What am I doing wrong?
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?

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?
View 6 Replies View RelatedI 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.

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 am using static Arrays and HashMaps to store some values in my AppWidgetProvider class. But they are becoming null when the process dies, so the widget does not work anymore. Are there any alternatives to using static members to store data for an AppWidgetProvider in Android?

View 15 Replies View RelatedI know I've asked a lot of questions about getting the stock Android apps and keyboards, etc. But I am very concerned as it may mean taking back my Eris.
For some reason, I just cannot stand the HTC apps. For example, the Messaging app, the black notification bar and different battery icon, the Mail app, etc. They just look cheap or something. I don't use Sense UI, I have it set to Default Home. I don't really like HTC's keyboard as much as the stock Android one either. I bought the Eris because of the price, and how much lighter and thinner it is and how much better it looks than the Motorola Droid. However, I would really love to know if we can get the stock Android look and feel, for example the stock Android keyboard, stock notification bar color, stock messaging app, after the 2.0/2.1 update or after it is rooted. It just looks so much more dark and rich. I don't like white color schemes like in the HTC messaging app. (And don't say use Handcent because I don't like it either and I don't want to replace any apps.) Is it possible to just install the stock Android OS after it is rooted?

View 1 Replies View RelatedI'm still a noob droid owner so maybe I just don't get it but here are some things that drive me nuts with the contacts interface.please note* I have (2) gmail email accounts, and a facebook account.
1. some of my contacts say they have "profiles" linked. so I tap the profiles and it will say for example "google: bob, google: bob, phone contacts: bob" why? I don't want anything linked. I feel like I don't have any control over my contacts.
2. I noticed that my fiance is a contact "julia" and then today I noticed another contact with her full name and a picture. so I ctapped that to investigate and it was her facebook info and email. where the heck did that come from? why on earth would I want more than one option for her as a contact?I am really lost. I mean REALLY lost. it took me a while to figure out how to make contact groups, so that I can organize some of my professional contacts but the rest of this is killing me. I created a new professional contact which happens to be a pest control guy. I chose to create a new contact. I entered his name and phone number, also email address. then I saved it. then when I looked at it somehow it had 3 linked profiles like what I was saying in point #1 above. what the heck?Why can't I just have a contact list period. and the only thing in this contact list are contacts which were entered into the phone by me. for each contact, I have the option to store their many numbers, email, etc. so when I tap on contacts, I get a contacts list and not a thousand people some of which are duplicates, some of which are emails I've responded to in gmail who I never talk to like customerservice@whateverbusiness.com.I'm mystified. can someone explain to me that either I am confused or this system is over complicated?
