If you go into the standard Note pad accessory application, the first available note menu entry is going to be...
<untitled>
My question is this: Where is "<untitled>" coming from in the code? The code is in the NotePad sample in the SDK if you want to built a project from existing source real fast. I just can't find where "<untitled>" is spelled out anywhere in the source or resources.
(Else, is this instead some kind of ultra low level string that Android's API hands to the GUI if there's nothing specified for a title? Which can't be changed?)
In the NotePadProvider.java appears that this string cames from android.R.string. To find that file you need to go here: SDKpath/platforms/version_you_are_programming/data/res/values. There is the string.xml file and that file is internal to the OS, I doubt you can change it.

I'm creating my applications. but i want to use android default drawables icon (calendar, camera or etc...)
some of icons can be use.
but some of cannot.
here is my code
android.R.drawable.ic_menu_camera it's okay to use.
but android.R.drawable.ic_menu_cc_am is error in Android studio
this file(ic_menu_cc_am) exists in android sdk and can jump to declaration like this.
why I can't use of this file (some of files also can't using on android studio, but file is exists!)
sorry for my bad english.
thank you.
How can i know which java file is used at the current time at that current interface. I know we can do this with a logcat when we know the source code , we can make everything log.i and stuff. but what happens when we don't know the source code or while assessing a black box android app
If you don't have access to the files how you supposed to know which file you are getting?
The best way to achieve what you want is to use a decompiler in your APK and do a debug.

I've build an application that uses Tesseract (V3.03 rc1) to identify some specific text strings. These are, unfortunately, printed on a custom font that requires that I build my own traineddata file. I've built the application on both iOS (using https://github.com/gali8/Tesseract-OCR-iOS for inspiration) and Android (using https://github.com/rmtheis/tess-two/ for inspiration as well).
The workflow for both platforms is as follows:
I select a bounding box on the preview screen for where I can crop out the relevant text, and crop the image accordingly.
I use OpenCV to get a binary image (using OpenCV's adaptive threshold function with the same parameters for both platforms)
I pass this binary image to Tesseract. Both platforms (Android and iOS) use the same traineddata file.
And yet, iOS recognizes the text strings perfectly, while Android keeps misidentifying certain characters (6s for Ss, As for Hs).
On both platforms, I use the same white list string, I disable load_type_dawg and load_system_dawg, and also choose to save the blob choices.
Has anyone encountered this kind of situation before? Am I missing a setting on Android that's automatically handled in iOS? Is there something particular about Android that hasn't crossed my mind?
Any thoughts or advice would be greatly appreciated!
So, after a lot of work, I found out what was wrong with my Android application (thankfully, it wasn't an issue with Tesseract at all). As I'm more familiar with iOS apps than Android, I wasn't sure how I could load the traineddata file onto the application without requiring the user to have the file loaded on their external storage device. I found inspiration in this project (http://www.codeproject.com/Tips/840623/Android-Character-Recognition), as they autoload the trained data file.
However, I misunderstood how it worked. I originally thought that the TessDataManager did a file lookup on the project's local tesseract/tessdata folder in order to get the trained data file (as I do this also on iOS). However, that's not what it does. It, rather, checks the internal file structure (data/data/projectname/files/tesseract/tessdata/traineddatafilegoeshere) to see if the file exists and if it doesn't, it copies over the trained data file it keeps in the Resources/Raw directory. In my case, it defaulted to the eng file, so it never read my custom font file.
Hopefully this helps someone else having similar issues. Thanks to Robin and RmTheis for all of your help!
I am having some difficulties with my android app parsing an xml that contains links to PDF files. It should open a listView showing all of the files listed in the xml. However, most of the time it just freezes up on me. The app was made by a developer no longer with us, and all I have is the apk and not the source files. Is there a way to use the apk to get the source files and figure out what the issue is? Android is not my forte and I'm at a loss with how to fix this.
UPDATE:
It appears that devices running 2.2 display all the songs just fine, while the newer versions of Android crash when ran.
I've had problems with android 2.2 on my HTC desire taking a long time to parse large XML files. There wasn't much I could do other than switch from DOM to SAX which for some reason was a lot quicker
However debugging this without source code is likely to be pretty difficult. Not least because fixing the issue when and if you find it will require you to re-compile a new class in replacement for the one which keeps freezing.
I would suggest you look into decompiling the APK back into source code.
According to Wikipedia APK files are based on the Jar file format which in turn is a Zip file:
http://en.wikipedia.org/wiki/APK_%28file_format%29
That makes this task a little easier as you won't need to look for a decompiler that is specific to android but a more generic Java Decompiler.
A quick search on google suggests this one:
http://java.decompiler.free.fr/
If you can decompile the app back to source code and then get that source code into eclipse and rebulild from source then you can start to debug.
I've created an app which pulls data from a JSON file and displays it.
Now that app is specific for one sports team. I want to create the same app for 10 other teams.
Plus there will be an accompanying pro version of the app.
I'll be doing the same thing for the iOS version.
The only difference between the apps will be colors, logos and url of the data source.
I wanted to know if there was a better way to create apps. Instead of individually creating 40 different projects.
It will help me in updating the app as opposed to copy pasting the same code 40X.
Are there any special features available in eclipse and xcode to do that?
Thanks
I would simply swap out the resources for each team and rebuild the app.
For example, with Android, maintain an AndroidManifest.xml and a res/ subdirectory tree for each team. When it is time to build, simply copy over the resources into the project, overwriting the previous team.
I don't know of any existing tool to do this automatically, however.
Have you looked into using PhoneGap and just create a "mobile site" that detects the app that is connecting and adjusts the data/styles accordingly.
There's always the possibility of creating ONE app allowing the user to set the team preference upon first load, and swapping out resources programmatically.
With Titanium Studio you can write code using Javascript and it convert your code in native objective-c code, native android code, native html 5 code and soon also in windows phone code. It`s the best free cross platform IDE
Upon reviewing your responses, you seem to want a strategy to manage your resources. Since different OS has different resource requirements (screen-size, iOS 2x png for example). The most common strategy is to keep a separate resource structure and setup build target to copy/xcopy replace these image resources before build. Source control + an OSX build server would be most beneficial.
After creating these apps I've found the following way to be the most easiest way to create a similar app.
Android:
1. Select the project from the project explorer sidebar copy it and then paste it. Give it a new name.
Select the new project and then right click > Android Tools > Change Package Name.
Give it a new package name. Eclipse will give you an option to refactor the code, say yes.
Go to res/values and change all strings.
Change the icons and other images.
Go to src click the package and then refactor it. Give it the new package name.
Go to manifest file and rename any old names which might still be lingering.
