Android : Required APKs To Maintain Running Droid OS?
Jul 2, 2010
Well, not sure if this was already somewhere else, but I looked and couldn't find it, so I'm gonna ask here...
What are the required APKs to maintain running the Android OS? I have root access on my Eris, and was tinkering around with a bit with removing some of the preinstalled APKs such as YouTube and stuff like that, just wondering how much I can delete and work to create my own system to a certain extent. Anyone that can let me know what I need would be nice.

I recently moved and had the opportunity to view my TV-channels on my phone. However it is required to have a device who is not rooted, and I don't really want to unroot just to view tv on my phone.
Any small program, script etc. which can tell the app that the phone is unrooted, even though it is rooted? My phone is a Samsung Galaxy Nexus, running stock unlocked and unrooted JB yakju 4.2.2.

I'm developing one of my first Android apps. I come from an ASP.NET world where it's trivial to have separate Web.config files for dev, test, and production. Does anyone have a good, automated way of doing this for Android via Eclipse?

I have a DIR-655 and just got my Droid X. It will not maintain a connection to it. I tried all the obvious things... Forced it to G only, tried using the guest zone with different encryption.

Why 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¦

The requirement is totally simple: I want to have a lite and pro version of an app. There is a little bit of difference between those two apps, but they are 99% identically. Unfortunately it seems that the best choice is to really treat this as two projects that are one and the same and copy over the source code and assets from one to the other. The Android Manifest file must be different, because the Android Market - for some reason - makes the implementation's package name the ID. Working around this ID issue the straight forward approach would be to have a third project with the common code that exports its code, libraries and in a best case scenario also the ressources to the other two objects. Unfortunately this doesn't work. Only the actual Android projects generate the R.class and so the common project would need to be dependent on it..

I just got the Droid 2 after using Blackberry phones for many years. I had the Blackberry Curve, and then went to the Blackberry Tour. For other users that have switched from a Blackberry, what sorts of things should I be aware of that might have been something I took for granted on a Blackberry that might require more of a work around on a Droid? I'm trying to get fully integrated to google apps for simplicities sake. I know there's the Push email thing, but I'm hoping just using everything through GMail will help that problem. I transferred my calender to Gmail from my Blackberry by exporting it to a Yahoo in syncing, and then going to Yahoo and exporting it to Outlook CSV, and then importing the CSV to Google.

According to the instructions found here, to make your app state which screen sizes you can support, you'll need to compile your app against Android 1.6.

During my game loop I am constantly loading images using BitmapFactory.decodeResource(getResources(), R.drawable.objectx); Most of the time I'm calling images that have already been decoded earlier. Am I slowing down execution by decoding the resource every time? Is it better to store every image into a Map (or Dictionary) at the beginning of the program? If so, how do you get the resource IDs for all images in the drawable folder?

Rooted tonight, and playing with ROM Manager and Bugless Beast V0.4 (Froyo). I'm wondering when installing a ROM using RM, it asks if you want to do a backup and wipe before installing. I have already done a backup and don't really want to start over with a completely blank slate once Bugless is installed. Is it possible to just install a ROM without doing a wipe first? If possible, should it still be avoided to prevent issues? Basically just wondering if a full wipe is needed/recommended before installing a new ROM.

This is more a question for those who have experience with rooted phones. For me, the biggest feature of Sense UI is how smooth it is in terms of transitions between screens, scrolling within things such as the Apps menu, etc. (couldn't really care less about the social networking integration).
Now, there are some homescreen apps out right now that are definitely (in my opinion) better in these regards than the standard Android UI, but they all still fall short of what Sense (or Rachael or even MotoBlur) has achieved.
Is this same smoothness, though, something that can be achieved if/when (since it really is just a matter of time) people figure out how to root the Droid and make custom ROMs?

I would like to know if its possible to prevent my application from looking different every time I run it on a different android phone. For example, on stock 2.2, my seek bar (with default values and theme) has an orange color for the selected portion, whereas on a Samsung Galaxy S (with 2.1), it is green. Also the tab background is grey in stock 2.2, but blue in Galaxy S. On a similar note, my rating bar changes size too. I do not implement multiple screen resolutions and all my drawables are located in the "drawables" folder under "res". I donot specify a minimum sdk requirement.

My ListActivity is bound to an ArrayAdapter where I have overriden the getView() method. If I change the visibility of a widget in that method or modify the view's background color, those changes somehow get lost once that modified list item returns after being scrolled off the screen. In fact, some other view in the list is picking up the changes. How do I get the modified view to look the same when it's redisplayed after scrolling?

This usually happens when the user hits "Home", does something else, then eventually wanders back into the app - it attempts to go back to where it was before, but the application Context has mysteriously lost all its previously-saved state information (in my case, a few integers and a few Strings). I know this is a very vague question, but are there any cases (other than the user using "back" to back completely out of the application) where the application Context gets completely destroyed even though the application is not terminated? Is there a better way to maintain persistent state information?

All this talk about different rooting methods and how some are unreliable makes me want to learn exactly what's required.
So far from looking at different exploits and methods to root different phones, the most simplest to understand is Peter Alfonso's Galaxy S rooting method posted today it seems all you need is to find a way on your device to install the following:
/system/bin/su (is this included in stock and replaced or just doesn't exist in stock systems?)
/system/app/Superuser.apk (it seems the Android OS has a "super user access" intent that this listens for -- so when apps try to access su this picks app it up?)

Is there an app that I can use to maintain the balances of multiple credit cards? The app does not need to be able to directly access the credit card's balances online (straight thru online banking), but I must be able to add transactions and update it manually. I also should be able to manage multiple cards without the app adding the balances of all cards into a grand total (balance).

Yahoo Mail. Looks pretty but wont download attachments and has no way to log out so there's no way to secure the account. Worst of all it screwed up the on-off switch and incoming calls wouldn't turn the phone on.(how I don't know) and required a hard reset to fix.

I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen.
With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition.

While developing a sample android application I have constructed two activities
1)Activity 1
2)Activity 2
Now Activity 2 is the foreground activity whereas Activity 1 is the background one. Now user presses Home key. The application(i.e. both the activities) disappear. Now is we relaunch the application we see Activity 1 as the foreground activity. My question is:
1)Does the platform maintain any history entry when pressed home key?
2)How do we take the user to the last launch activity on relaunching the application?

I'm interested in knowing how other people maintain good battery life with their evo. I get about 5 hours a day with moderate usage. I don't do much but put the screen brightness in the middle and occasionally going into "running applications" and closing the ones I don't need or use (most of them being the trashy default stuff); Turn off syncing when not needed; turn off GPS and other seetings that are not continuously needed to be left on.
I also configured my send and receive settings for each mail account. I know there is no official way to close out an app when your done using it, I usually just press the home button when i need to exit an app. Does everyone else do the same? Or is there a better technique to officially close apps and stop them running when you are done using them? Without DLing a task killer app cause I don't want one.? Feel Free to share your ideas or techniques.
