Android :: Roadmap To Development - Lesson Plan For Starting From The Ground Up?
Mar 27, 2010
I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game.
Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan?
I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

I recently tried out the applicationCache / offline web apps on Android 2.1's WebKit and unfortunately it does not work exactly like on a webkit on the iPhone. I was wondering how I can easily see what features should be implemented and if there is something like a roadmap?
Does that information somewhere exist?

Original article:
http://www.xperiax10.net/2010/09/11/android-roadmap-leaked-for-xperia-x10-family/
We have been sent what is believed to be the Android roadmap for the Sony Ericsson Xperia X10 family. It is in German and originates from last week's IFA show in Berlin. We can't verify whether it is real or not, but it appears legit to us. The roadmap highlights three major firmware releases: Android 1.6x, Android 2.1 and Android 2.1x. It shows that the Android 2.1 update for the Xperia X10 will get 720p video recording with continuous autofocus. HTML5 will also be adopted along with 5 homescreens and a social phonebook (facebook/twitter integration with your contacts). The document also points to a revised menu.
For the X10 mini, X10 mini pro and X8 the 2.1 update will bring with it a slight change in the four-corner navigation along with Bluetooth 2.1. These mobiles will also get the social phonebook and HTML5 adoption. Following this, there will then be the Android 2.1x update that will bring Sony Ericsson's revamped UX platform to Timescape and Mediascape along with more languages. Unfortunately, the roadmap for all handsets stops at 2.1x so I wonder whether we'll ever see Android 2.2 (Froyo) on the X10."
Update: According to forum member steinii1488 of se-world.info the Android 2.1 update is expected in October/November (this could be a regional thing as SE UK have promised an update by the end of Q3). He goes on to say that the Android 2.1x update will fall in December 2010/January 2011. This means that if SE is planning a Froyo update for the Xperia X10, it won't fall in 2010.

I have a weather image I would like to use as an overlay in the google maps android api. I would like to achieve the same result that I get from using GroundOverlay in KML files, such as
<GroundOverlay>
<name>myimage</name>
<Icon>
<href>myimage.png</href>
<viewBoundScale>0.75</viewBoundScale>
</Icon>
<LatLonBox>
<north>75.6088</north>
<south>5.0121</south>
<east>182.2805</east>
<west>120.6795</west>
</LatLonBox>
/GroundOverlay>
The above will ensure that the 4 corners of my image stay anchored to the 4 lat/long points listed, regardless of scrolling, zooming etc. Is there a way to accomplish this using the google api / maps provided for android?

My device is a galaxy tab 7 plus and we currently have a fully functional CM9 build working perfectly. I've been following a few guides on how to port AOKP to this device and non of the guides worked. I also read that cm9 and AOKP are one of the same. So if u get one to work the other should just as easily. But it doesn't seem to be working. So I figured maybe porting won't work. Maybe I have to build it from ground up. Or is there a way I can bring the RomControl menu to the current cm9 build?

I created an application which is asynchronously communicating with the server. When the application makes a server request a new dialog (activity) with "loading" notification is created. The main activity implements methods for handling server responses and I would like to close the foreground activity when the main activity receives the answer from the server.

I have google voice. And the quality is excellent but im on a non data plan so I can't check it out in 3g. I live in a t-mobile edge zone so I want to know about the voice quality & reliability cause I'm planning on getting a nexus with a t-mobile data only plan. Will it be like a regular phone call or will I have poor quality?

I've tried searching for an answer to this in the forums but I can't find someone who has already asked it.In any case I'm wondering whether its possible to use a Nexus One without a data plan. I have access to wifi pretty much everywhere I would use my device and thus a data plan really is not worthwhile for the cost.That being said I know that for other android devices, the very first time they're turned on, the user is required to connect to their Gmail account via data. Would I run into a similar situation with the Nexus One? Is it possible to use the device from the get go without any data? Do any of the primary apps(besides google maps obviously) absolutely require data to be used?

We bought a G1 off of a 3rd Party Carrier (brand new), and activated it via Wifi.Tmobile was able to recognize it when we put the sim card in.(the picture of the phone appeared when we went to account settings within the tmobile website).So basically, we have an unlimited text and messaging plan. and NO data plan.
The internet works fine on the phone when using wifi. However, we are having issues with picture messaging. We receive the text message + picture attached, however, the g1 will not let us download it. I have looked around and seen workarounds for this error.One method was to forward the text to an email and download it from there. However, we could not get this to work.SO my question is,What (if any), is the most up-to-date method to get MMS over Wifi without a data plan.

I'm looking at downloading a golf app that utilizes GPS location for my Droid Eris. I have Verison with the unlimited mobile web and email. Does the GPS service fall into that or is it something seperate? Couldn't find any answers at verisonwireless.com.

I really want to ditch my SMS plan, but the GV notification is spotty at best. I thought SMS was push now? As in, you get an SMS/VM/ETC, Google Pushes a notice to your phone to sync, then your phone syncs? It seems like it's still just checking every 10 minutes or whatever. I also have the extension in Chrome that shows your SMSs, and the two don't correctly correspond on new messages.

I have searched, but cannot seem to find exactly what I'm looking for. I bought the phone unlocked so I'm not held down to their plans, so what do I choose? I want 750-1000 minutes I'd think ( I use around 800 now ) , have to hve unlimited everything else. Currently I have a Tmobile Sidekick LX with 1000 minutes, and unlimited everything and its 69.99 per month.

I'm new to AF, but I've been lurking here for about 2 months. Did my homework and ended up buying the Samsung Moment and Samsung Exclaim for my girlfriend and I with a new Sprint contract. We're both thoroughly pleased with our phones and our plan.But I do have a question that I haven't seen addressed here. I jumped through all the hoops and was finally able to install PdaNet 2.17 on both my computer and phone. I tested it a little after getting it connected and was pretty well pleased with the performance of both the phone and the software. However, I will not be tethering my phone again until I can find out whether or not Sprint will bill me for it.As far as what I can tell from online sources the data plan truly is unlimited and Sprint cannot tell for a fact if my phone is tethered or not, although the bandwidth usage will be significantly higher during tethering sessions. BUT, a friend of mine informed me that Sprint knows when you're tethering and will charge you as if it is a separate line or however they can. All I heard was that it would cost me.I'm sorry for the long post, but I included the details for clarity's sake and as an insight into the kind of posts the AF community can expect from it's friendly neighborhood HampMan. Any input to the subject matter will be greatly appreciated and I thank you all in advance.

I'm thinking of buying an unlocked android phone and using it without a data plan, I can live with wi-fi only. But with which carriers am I able to use my android without automatically being charged for a data plan, unlike AT&T?

I'm new to Android platform but not new to software development. We want (in our company) to create Android software to compliment our truck management software. Basically, it will do couple very specific tasks.
a. Send GPS updates to server.
b. Receive trip information.
c. Send pickup/delivery confirmation to server.
After evaluating i.e. platform and Windows phone 7 platform we came to conclusion that only Android has multitasking that works for us. So, Android it is but I have some specific questions.
1. Data plan we want to use will be very limited. Probably 5M/mo and no voice/text. I figured 5x1024x1024 = 5242280 bytes will give me 1k per transmission every 15 minutes (3000 transmissions per mo). It will leave 2M for other stuff that will happens every couple of days. Does my math look OK or there is lot of "waste" traffic? Our server going to be XML SOAP and messages sent will be just Lon/Lat in XML package. 1K will be OK? If I just calculate bytes it will be even less but I wonder if there is "minimum" packet size, etc. Any insight on this data limitation appreciated.
2. Because of #1 we need to "lock" device somehow so there is no other software that uses network. Possible? If so, what do I need to look for? I found already created app - firewall and it says phone has to be rooted for that.
3. Receiving trip information. What's the best way to accomplish that given my situation? Should I run some kind of listener? Will my phone have IP address or something? Or should I get small text plan and use that for this specific functionality? Can I receive text message in my own application?
So, as you see we trying to shrink $80/mo service to $15/mo service that will do big savings to our company but not sure if it's all possible with constraints we have. Also, we may just give discounts to drivers who have Android phone and will install our app but we don't count on that.

I have two EVO's, and I'm on the absolutely unlimited everything plan for both phones, which means that on a monthly basis Now, if I moved down to unlimited everything plan except for calls to landlines, I could save a lot. As I understand that plan, all calls to any cell phone are unlimited, but I would have a minutes cap on land line calls during the day on weekdays. So, can I use some kind of App to make land line calls during the day on weekdays and avoid the charge to my limited land line minutes? I would want an App that allows calls to be received and placed. I think there is an App for that, but it requires a new number to be registered?

I am finally ditching Vonage. I got tired of taking the receiver everywhere I go. I want to place VOIP calls on my EVO.I am looking for a replacement. Of course I would like to use my data plan and/or WiFi to place VOIP calls.I have read several threads on how to configure SIP clients to get free calls over WiFi; but that's not really what I am looking for. I place a few calls abroad on a regular basis. I need to find a VOIP provider (I don't mind paying) that is compatible with a SIP client on Android.I have looked around and found a couple of companies. these three have caught my attention.Does anybody have any experience with any of these companies? How is the service? Do you really get what you pay for?Would you advise on other solutions?Please share your experience. Any help would be greatly appreciated.

I searched here and on google and did not find a definite answer.
I'm looking for a way to circumvent AT&T's forced data plans (there's wifi EVERYWHERE!!). As far as I know, AT&T towers can read the IMEI number of the phone you are using. That tells them what phone it is, where you got it, and what version it is. So when AT&T sees that you have your sim card in a smartphone, they send you a text saying, "we slapped a data plan onto your account". However, I think that maybe AT&T can only enforce the data plans on phones sold in the US.
My dad got a Nokia N85 (this is a smartphone, right?) from China and has been using it for at least two year now and he's not getting a forced add-on data plan. It could be because he was using the phone without a data plan before the smartphone+data combo that he's not being charged. We just renewed our contract, but my dad did not get a text about adding data charges, or AT&T will charge him without notification at the end of the month.
Does anyone else have a foreign smartphone in the US on AT&T? Any data charges?

Does Sprint or any other carriers provide pay-as-you go service that can work with the Evo 4G? I bare use any minutes per month and have wifi internet access all the time during the week. I see no reason to subscribe a monthly plan that I don't use often.

With all this talk about people buying the i7500 from Germany; I was wondering if T-mobile has any rules/detection against us using an android phone bought from outside, on the network using a normal voice+data plan like the $30+$10 plan. Because given the price difference of a 2 yr contract a new phone would in theory need to be over $560 before it is no longer worth buying outside. So what is the incentive of getting a simlocked phone, that costs more, and be locked into a 2 yr contract? I guess this applies to some of the other smartphones as well.
