Today I got my first android phone. It is the Samsung Galaxy Spica.I don' t know anything about android phones so I need someone to show the first steps and explain to me the specifications of this operating system.I have a problem with my WiFi. The phone finds my network, I give the password but it says "Connection failed". Can anyone help me?

I seem to have an intermittent error when trying to start WiFi. Mostly (>95%) of the time I get "unable to start WiFi". Occasionally it works but this is rare and usually when it has been switched off for a few days. The problem occurs when I try to start via the wi-fi widget or via the MenuSettingsWireless controls path. I'm reluctant to do a factory reset unless I really have no other option.

View 2 Replies View RelatedHere http://source.android.com/submit-patches/code-style-guide#shortmethods it is stated that :
"Field Names
* Non-public, non-static field names start with m.
* Static field names start with s.
* Other fields start with a lower case letter.
* Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.
also states that : "The rules below are not guidelines or recommendations, but strict rules. You may not disregard the rules we list below except as approved on a need-to-use basis." I don't like the "m" convention before private or package fields in a class... I really find this uninspired. I mean, if we try to apply good designs, the low coupling of the classes implies having few public fields. actually, in my programs I usually have no public fields, even when I need some I use getters and seters. so, why should I be forced to have almost all my fields in the program with an "m" in front of them? wouldn't be easier to have the few public fields, if there are any, with some "g" in front or something? or just use setters and geters as beans suggest? this really makes my code harder to read. also, following these guidelines, local temp variables used in the methods have no restriction so they could easily be mistaken for public global fields (also without restriction). this also I find to be wrong, as it is a probable source of mistakes. I understand to have a way of differentiating from fields, but private/protected member fields are the most used in an application, they shouldn't be less "readable". what do you think? should I follow the guidelines?
Im trying to prepare a set of guidelines and project template for my future Android projects. Im already implementing the basic MVC architecture modularity. Im trying to have add more advanced level of design to my Android projects to make my development easier and maintainable. For example can someone suggest me a way to make Intent calls to Activity without explicitly mentioning the class while creating the Intent. Im trying to loose couple the intent calls and hopefully use AndroidManifest to assign action to an activity which then can be called globally within the application.Any other type of suggestions are welcome. Also please suggest any kind of coding conventions that you might be using yourself.

View 1 Replies View RelatedI'm making an ecommerce application on Android and, as it is my first serious project, I'm trying to figure out beforehand the best approach to do this.The application talks to a web service (magento api, meaning soap or xml rpc unfortunately) and gets all the content on the phone (product categories, product details, user credentials etc.). I think it should do lazy loading or something like that.
So, I was thinking to keep the user credentials in a custom Object which will be kept in a SharedPreferences so that every Activity cand easily access it. I'll use a couple of ListViews to show the content and AsyncTask to fetch the data needed. Should I keep all the data in memory in objects or should I use some sort of cache or a local database? Also, I'm planning to use a HashMap with SoftReferences to hold the bitmaps I am downloading. But wouldn't this eat a lot of memory?How cand all the activities have access to all these objects (ecommerce basket etc.)? I'm thinking of passing them using Intents but this doesn't seem right to me. Can SharedPreferences be used for a lot of objects and are there any concurrency issues?
Any pointers would be really appreciated. What are some good guidelines? What classes should I look into? Do you know of any resources on the Internet for me to check out?
calling MediaPlayer.onStart() from Activity.onResume() (after the Activity has been paused) causes the following messages in logcat: MediaPlayer start called in state 64 MediaPlayer error (-38, 0) MediaPlayer Error (-38,0) Now the question is, what are the messages trying to tell me? What state is 64?

View 3 Replies View RelatedI accidentally imported a resource file with a capital letter in the name (SDK 8) and as we all know, that corrupts the R.java file in a way that rebuilding the project doesn't fix (I renamed the file to something legal from within Eclipse, of course). So now the build chokes with the error above when it hits the first xml file in res. In SDK 7 the only fix was to build a fresh project and move everything over. I'm hoping there is something better in SDK 8.

I have created the Client-Server application. At the Server site i have used the AIDL to impliment the interfaces in my Service class. At Client site i have exposed the AIDL interfaces and have one Activity that mainly do the IPC mechanism , i mean ServiceConnection, bindService and then call the Serivce of the Client site. But i am getting the error i mentioned during the bindService call.
Could you please let me know the steps mainly i have to follow to run the Client -Server Application. For time being i am running the Client .apk first and then the Server .apk, but the server one giving me error.
It would be great if you could let me know what all permission short of thing to take care, as my Client and Server code are placed at different APks, so do i need to import the Client project in my Server Project, if yes then how to impliment that.
I am getting this and can't seem to find out why?

Here is the code where I am trying to start the activity

Also the activity will start if I take out the intent.putExtra(BeerForm.INTENT_BEER_ID, String.valueOf(id));
I am looking for a way to get my wifi to start on boot. I hate going to the settings every time especially when some programs start searching for the connection automatically. I didn't know if there was a setting or an app to get it going.

I just got a htc hero today. When I first got home with it, I used the wifi to connect to my router. Now it says "unable to start wifi" Have I done something or do I have an issue with my phone?
View 20 Replies View RelatedI'm getting this problem where I can connect to WiFi the first time with no problem but once I disconnect and the phone sleeps, it can't connect to the network again and says "Unable to Start WiFi", I can't even get to Wireless settings because it can't start the WiFi.
It's the same story with Bluetooth. It'll work once.
If I turn the phone off and then on again, it will work once more but only ONCE before doing the same thing again.
I do know that downloading on Wi-Fi is faster than using data (or so I've read). My question is if I start a download using data connection then turn Wi-Fi on will the download see the Wi-Fi and jump on that to speed up our do I have to start on Wi-Fi for it to use Wi-Fi?
