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.

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'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.
I am programming an android application and I'd like to use the system icons for mail, phone, calendar and contacts inside this application. The problem is, that these icons differ from system to system (different android versions and different smartphones) and I want to keep the application and the system consistent. Is there an easy way to achieve this?
In XML use default android drawables from #android:drawable/... and in code use android.R.drawable....
You can use the standard drawable using
#android:drawable/[icon_name] in your xml file
android.R.drawable.[icon_name] in your java code
You can see different icon in your file system in
[SDK PATH]/platforms/platforms/[ANDROID_VERSION]/data/res
Some images are standard...like contacts, calendar :)
You can't keep system consistent. For what? New versions of Android are usually prettier than older ones (well, it's my opinion).
The only way to keep system icons same for your app - copy them into your drawables instead of using direct reference to them (like #android:drawable/).
First of all if you intend to use the default images (icons) for mail , phonr etc.
This default can be used as android.R.drawable.name in code or #android:drawable/ in xml from http://docs.since2006.com/android/2.1-drawables.php
But as this will vary from OS versinos to Versions.
So , if you need to use an unique GUI for the app for all versions and devices.
Please do not use android provided images , simply use your own graphics or images supplied in drawables resources explicitly by you for your app.
If you're ok with icons from each system you can get it via PackageManager and getApplicationInfo method.
If you're not, you should copy the resources from the platform into your own application.
I remember seeing how to do this somewhere, but I'm totally drawing a blank right now. I'd like to use the Android "Refresh" graphic in my application, how do I reference it? Is there a chart somewhere of all graphics which are provided?
Easiest way is to look in your Android SDK location (on my machine, that is *C:\projects\android\android-sdk-windows-1.5_r1*): in the platforms folder is a separate directory for each version of Android. Pick your version of choice and then open the *data\res* folder: there will be a number of drawable folders with the platform graphics.
Go wild copying them into your own app.

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.
