I just started looking at the android framework and was wondering what was the best way going about getting good at it. I started with a text game and created a simple bubbleWrap game next. But am not sure if I'm going about it the right way now, so I thought I'd ask some of you more experienced Android people out here. Are there any courses online that would be beneficial? Any books that helped y'all?

View 2 Replies View RelatedWhat has people's experience been in learning Android? I'd be interested in how long it takes to get to the point where you're writing your first app, and how the experience compares to learning some other programming API. I know several professional programmers who have tried to learn Android and failed. Is it inherently more difficult or larger than you might expect? But there's a survey here http://www.infoq.com/news/2010/07/Mobile-Survey that claims Android has the shortest learning curve of all smartphone platforms. I wonder how the survey guys could have got such a perverse and unlikely result. I have my own views and observations on this, which I'll mention as a dialog develops. I don't want to bias the discussion with my perspective at this point.

View 2 Replies View RelatedI am planning an app using the android speech input api (Speech Input | Android Developers). How the learning occurs? So for example initially my phone could not recognize proper nouns, local locations, uncommon names of my friends, etc, but now it recognizes all of these things so clearly it has learned. But are all of these words now available to other users?
I am envisioning an app when each of my users would be contributing to a database constructed by other users, so that a proper noun that someone else entered is now available to be recognized by someone who has never used my app, is this something I can count on happening automatically?

View 2 Replies View RelatedWhy did I do this? Well, I wanted to use Fightspit's circular battery icons. The DX's icons only change every 20% which is kind of useless for the icon set I wanted. It's easy to swap out icons (via 7zip) but adding icons creates a lot of problems. This forced me to come up with a workaround. Here's the process in case anyone else has been trying to do this.
---------------
Whats needed:
ApkManager
The themed framework-res.apk file
Extract framework-res.apk from any themed zip file
Or adb pull it from your THEMED phones system/framework directory
Stock framework-res.apk file
Extract this from TBHs deodexed 2.3.15 leak
Or adb pull from your STOCK phone
Batter and charging icons
I use 0, 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100 battery icons since the DX only reports battery readings in 10% increments.
I have 20 charging pngs. You can have more or less but youll have to modify some XMLs (see below) to get them to work.
You can use UOT Kitchen to generate battery icons. There are, also, other icons floating around on XDA. Just be careful to use HDPI compatible types.
The attached decompiled XML files (these go in the DECOMPILED drawable-hdpi folder along with the batter icons). Edit these if you add or remove pngs.
7zip or Winrar (I prefer the former for modding .apk files)
Working knowledge of DOS (optional) or patience
DIRECTIONS:
Stock framework-res.apk prep
Extract ApkManager (you can put this anywhere. I have it on c: to make things easier in DOS)
Put your STOCK framework-res.apk in the place-apk-here-for-modding folder
Run the script and DECOMPILE (Option 9) the apk. The decompile folder will be in the projects folder.
Delete the STOCK framework-res.apk from the place-apk-here-for-modding folder
Move the DECOMPILED framework-res.apk folder from projects into the main ApkManager folder. This will be your repository of stock files that you will need later
Themed framework-res.apk prep
At this point you should have NOTHING in your modding folder AND project folders
Put your THEMED framework-res.apk in the modding folder
From the ApkManager root folder, DELETE the log text file
Run the script and DECOMPILE (Option 9) the themed apk.
After the decompile is done, close the script and open up the newly created log.txt file
In the log youll see some .9.png errors in /res/drawable-hdpi folder. These are files that were not decompiled properly because some required information (9patch) was missing. Each of those 9.png files will be decompiled (wrongly) and then renamed to .png. Therefore for every SINGLE 9.png error file, there will be one USELESS .png file. NOTE: If you try to recompile with these broken 9patches, the resultant apk WILL cause you to bootloop.
Lets pause here for a bit:
All the 9.png files listed in the error log, as stated before, are BROKEN. The decompile script aapt (apktool) decompiles these broken 9.png files, makes a copy of said files, and renames the copies as *.png.
So, there are, actually, two broken files (one 9.png and one .png) for every error in the log. You have to delete BOTH of these files and replace them with healthy files from the stock framework we decompiled earlier. If you skipped that, go back up and do it. The awesome thing is that there are hundreds of healthy 9.pngs and even more .png files in your THEMED framework decompiled folder. Locating each of this files (sometimes 30 x 2) is a pain. My workaround is to use good ol DOS. You dont have to do the next few steps with DOS but you have to reach the same end.
Enter the dra¦ er decompiled framework-res folder in /projects.
Copy/mark the error 9.pngs into MS Word (or whatever you use). Keep Word and DOS open till were done with this part.
Using find and replace do the following:
Copy everything before the 9.png file and find/replace that with del.
Copy everything after .png and find/replace it with NOTHING (dont type nothing)
The outcome should be:
del first_example.9.png
del second_example.9.png
and should contain all the broken .9.png files
In DOS, cd to decoded frameworks folders drawable-hdpi folder
Copy and paste the contents of the Word file into DOS to delete all the broken 9.png files.
Go back to MS Word and find/replace .9.png with .png
The outcome should be:
del first_example.png
del second_example.png
and should contain all the broken, renamed .png files.
If you didnt close the DOS window, just copy and paste the modified contents of your Word folder into DOS to delete all the broken .png files. If you closed the DOS window, shame on you :P. Youll have to open DOS again and navigate back to the decoded frameworks drawable-hdpi folder first.
You should have removed both the BROKEN .9.png and .png files from the decompiled frameworks drawable-hdpi folder
Head back to MS Word one last time and edit the files to look like this
copy first_example.9.png c:APKManagerprojectsframework-res.apk
esdrawable-hdpi
copy second_example.9.png c:APKManagerprojectsframework-res.apk
esdrawable-hdpi
etc.
The c:... will vary depending on where you put your APKManager folder. If you put it somewhere else, copy the location from your address bar.
Head back to DOS and cd to your STOCK folders drawable-hdpi folder.
Copy the contents from MS Word into DOS and this will copy the healthy .9.png files to your THEMED decoded frameworks drawable-hdpi folder.
You can close MS Word and DOS at this point.
Replacing the battery icons and xml files.
Navigate to your THEMED decompiled frameworks drawable-hdpi folder.
Paste your new battery icons into this folder (overwriting all the existing ones). The files to look for are stat_sys_battery_X.png and stat_sys_battery_charge_animX.png
You should also replace ic_lock_idle_charging and ic_lock_idle_low_battery (I use the fully charged and the battery unknown pngs respectively)
Replace the xml files with your modified ones. The files to replace are stat_sys_battery.xml and stat_sys_battery_charge.xml.
Rebuilding your framework-res.apk
At this point you should have your THEMED framework-res.apk in the modding folder and your THEMED, decompiled framework-res.apk folder in the project folder (with your new png and xml files.)
Go back to the APK Manager main folder and run the script.
Compile the apk (Option 11)
You will be asked if this is a system apk. Choose YES.
You will be asked if you want to copy all unmodified files from the oringal apk. You can choose NO.
Sign the APK (Option 12).
Go into the modding folder, you will find a signedframework-res.apk
Open (DONT EXTRACT) signedframework-res.apk with 7zip or Winrar.
Open (again, DONT EXTRACT) the themed framework-res.apk (also in the modding folder) with 7zip or Winrar
Delete, from within 7zip, the META-INF directory and AndroidManifest.xml file from signedframework-res.apk
Copy, inside 7zip, META-INF and AndroidManifest.xml from your original themed framework-res to signedframework-res.apk Dont unzip anything.
Still in 7zip, navigate to /res/drawable-hdpi in both the original, themed framework-res.apk and signedframework-res.apk. Delete everything BUT the new (stat_sys_battery stat_sys_battery_charge) xmls and battery and charging .pngs from signedframework-res.apk. If you used my files, there will be only 40 items left.
Finally, copy (still in 7zip) everything BUT stat_sys_battery.xml, stat_sys_battery_charge.xml, and the battery and charging .pngs from the themed framework-res.apks drawable-hdpi folder to signedframework-res.apks drawable-hdpi folder.
Your modified framework-res.apk is ready to be pushed to your phone.
Putting the files on your phone.
Either push signedframework-res.apk to your phone via adb or
Create an update.zip for use with clockwork recovery. You can also take the themes zip file and replace the framework-res.apk as well. (I like this). Or you can just make one if you like.
Reboot your phone if you used adb and welcome to 10% heaven.
Im hoping our themers will incorporate the 10% hack into their themes. For them its only a matter of replacing the (2) xml files before compiling the theme.
Ill try to answer any questions as best I can.
Also, please donate to the DEVs (not me!) if you can. This little task took me almost a week (after work and no SSF4 for me ) to figure out. Imagine how much work is required to bring ApeX, RubiX, ZapX etc¦
Grab the Apex rEVO and NexTheme mods and files at:
REVOlution theme with 10% Circle Battery MOD and NexTheme 10% Circle Battery Mod.
Decompiled XML files
If anyone can upload the stock services.jar and stock framework-res.apk from their 2.1 Droid X (it's in the /system/framework folder), I will be forever in your debt. I (stupidly) overwrote mine when installing a theme and now I can't update to 2.2 with my modified files. I know I can flash the .sbf, but I am trying to avoid that.
