I know many similar questions have been asked for example this one. Mine is slightly different. I create a new android project using all the default settings (target SDK 4.2 Jelly Bean, min SDK 2.2 Froyo). The project is created without an R file. I tried cleaning the project and nothing happens. I tried looking for errors in the res folder and nothing happened. All my XML file names are lower case. What could I have messed up to cause brand new projects to not generate R files? Is there some Eclipse configuration that needs fixing? Is there some Android module that I haven't installed? Any help would be greatly appreciated.
make sure you have android sdk build tools installed from the sdk manager if you have updated adt to rev 22
Install it resart the eclipse and make clean and rebuild project it will work

I am used to developing for android with android studio. But since my Project (OCR) doesn't seem compatible, I wanted to switch to eclipse.
Since the eclipse version downloaded with the SDK was outdated, I dowloaded the newest Eclipse for mac.
After linking it with my NDK and SDK it had a problem, so I used copied the code (not the files) from an working android studio app into the right files.
My Problem is that eclipse can't recognize R. And I can't run my project.
So again, I am running an mac with newest NDK and SDK as well as freshly dowloaded eclipse.
Eclipse didn't recognise R. because it can't build it. R. sometimes can't be generated from xml problems (like layouts or androidManifest). Last thing is the project.properties file. Try modifying it using only the neccessary things.. (target= ... and your references).
Recently I updated my eclipse Juno to Luna, but now the new project don't generate the android.R file. This probably caused by this AndroidManifest.xml error:
Error: No resource found that matches the given name (at 'theme' with value '#styles/AppTheme').
When I check the values folder, there is no styles.xml.
This only happens with the new projects, the existing projects (which I created in Juno) work fine.
I've tried updating everything in SDK manager, but I still get the error.
I don't know the specifics, but I just fixed this on both my Linux machine and Windows machine. It stops producing the style.xml after you upgrade your Android SDK Tools to revision 24 or higher.
I fixed mine by downgrading as seen at this other SO discussion using the version 23.0.5 (I'd post direct links, but I don't have enough points here to post more than two).
Again, I have no idea WHY this is happening, only that it prevents me from creating new projects with the latest SDK.
I met the same problem when I updated my Android SDK Tools. When I build a new Android project, it doesn't generate the styles.xml in res/values/. But after I builded a new styles.xml and copied content from other project, the problem disappeared.
The error has been corrected in Android SDK Tools 24.0.2. I just test it now.
If it happened during your first Andriod App build, it must be just like my case.
It happened to me when Eclipse(Luna)/AndroidSDK(not Android Stduio) were used with the latest tools and library as of Jan. 14, 2015 during the project like HelloWorld. When I installed those tools and made HelloWorld the first app, I accepted all the defaults. - This is the problem in my case.
First, check whether or not the "Android Support Library" library is installed.
If not, install it. It is not installed by default.
You may do it all in "Android SDK manager" available in the menu.
(Android SDK Manager -> Extra -> Android Support Library)

First of all, i know this question has been asked a lot, but nothing seem to be working for me.I have installed Eclipse ADT On MAC 10.9.5 from android.developer.com and have installed latest Android SDK tools, and all other platform and tools required for Android 5.0, android 4.4W and Android 4.4.2. I have also installed Android support library. But when i try to run the project with the default properties,
http://postimg.org/image/4lf8ayl99/
Minimum Required : SDK-API8:Android 2.2(Froyo)
Target SDk-Android; 4.x(L Preview)
Compile With ; API 21: Android 4.x( L Preview)
It always give me error,
The container 'Android Dependencies' references non existing library '/Users/xxx/Documents/workspace/appcompat_v7/bin/appcompat_v7.jar'
I went through all the solutions listed on web and on this website too, but nothing worked for me.
appcompat_v7 library gets generated, and then i click on add to build path for android-support-v7-appcompat.jar and android-support-v4.jar, and then from build path add the two libraries and untick android dependencies and add the library to my project from android library. From other posts i get to know that after clean and build appcompat_v7 library project , appcompat_v7.jar would be generated in bin directory, but it doesn't happen in my case.
Please help. I have spent too much time looking for the solution, but didn't find any.
I finally found the solution, I had to update the jdk to 1.8, The jdk installed by default by eclipse ADT form android.developer.com doesn't seem to be updated and Since API 21 requires jdk 1.7 or above thus i had to install it from JDK official website http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html. Finally i got the support library appcompat_v7 working.
I had the same problem and I tried and after that message I got another from the res folder. Anyways what I did was switch work space and it worked fine . it should create those files for you as long as you downloaded the extras from android manager downloader.
I have an Android SDK which I keep updated with the tools and platforms that I need,I recently felt that it was time to migrate to Google's new Android Studio IDE after Eclipse destroyed my workspace for the zillionth time,instead of unzipping Eclipse I downloaded and installed Android Studio and tried to import a project,it looks like the IDE comes with an SDK of it's own.I would like to add path to my SDK folder and my NDK folder as well.
You've got SDK manager just as in ADT. It didn't let me change the SDK directory, though.
So, go to "Project Structure" menu (or "Other Settings/Default Project Structure"), and set the home path for Android SDK. here is a bit outdated tutorial: the GUI has changed since v.0.1, but the substance is still completely relevant.
A week ago, v.0.4 preview has been released - maybe the menus have been shuffled a bit again, I don't know.
PS: note that NDK integration is still not official, but some workarounds have been accumulated here.
I downloaded Android Studio, fixed the JDK Environmental Variable, but when I try to create a New Project, I get an error that says
Your Android SDK is out of date or is missing templates. Please ensure you are using SDK version 22 or later.
I opened up android.bat in the SDK but it said I was already running version 22.
Anyone else getting this?
It just happened because you already have your SDK setted up for Android Developers Bundle with eclipse. Simply open your SDK manager in the ADT Bundle and update you Android SDK Tools from 21.1 to 22 and you are good to go.
Worked for me.
First of all, on Windows and Mac, the individual tools and other SDK packages are saved with the Android Studio application directory.
Windows: \Users\<user>\AppData\Local\Android\android-studio\sdk\
Mac: /Applications/Android\ Studio.app/sdk/
Make sure your android-sdk-path is correct and the sdk tool version is 22 or later.
Then open the Configure--> Project Defaults --> Project Structure, set your project sdk is Android SDK.
enjoy.
As for me, I make next:
Start Eclipse -> start SDK -> install selected packages
Eclipse -> Help -> check for updates -> update all
Android Studio -> configure -> Project Defaults -> Project structure -> Press plus -> Android SDK -> put path to the same sdk that you use in eclipse (run SDK and in top panel you can see this path).
Apply
I did all of the above and still got the ....missing templates blah blah. What worked for me was to go to Configure>Project Defaults>Project Structure>Project and select Android SDK, then Configure>Project Defaults>Project Structure>SDKs map the Android SDK home path to the sdk folder in the ADT bundle (for me it was C:\Users\home\Toolbox\adt-bundle-windows-x86\sdk).
I then selected Android 4.1.2 clicked apply and it worked.
I then went back to the Configure>Project Defaults>Project Structure>SDKs and then selected Android 4.2.2 and now that worked too (strange though as when I selected Android 4.2.2 first time the Apply button was grayed out)
I ran into this problem because I wanted to update from an old version. In doing this, I downloaded the latest version from the Project Tools Site, then unzipped and copied over my existing Android Studio install which did have the sdk folder inside.
Going back and looking at it, I see quite plainly that there was a note that I previously ignored:
NOTE: These .zip files do not contain an embedded SDK install. If you have an existing install of Studio which contains an embedded SDK, if you upgrade by installing one of these zips, make sure you copy over the SDK as well.
For OS X users, this means going to your old version of Android Studio (if you haven't copied over it yet) and right-clicking and selecting Show Package Contents, then copying the sdk folder that's inside, then putting that into the new version of Android Studio.
If, like me, you already copied over the old version, then you'll need to redownload the old version first which does contain the SDK.
They released a new sdk today. You need to update to it.
I was still hitting this, and figured it was due to something I had misconfigured (which turned out to be the case). The error message is a little confusing, too, because I believe that they are referring to is the version of the ADT tools, not the SDK. For example, the version of Android 4.3 (which is about the latest) is 18.
As of the latest source for Android Studio (which you can clone from here: https://android.googlesource.com/platform/tools/adt/idea), that message is generated from NewProjectWizard.java at about line 75 if TemplateManager.templatesAreValid() is false. And it checks that by looking for the existence of the file [rootTemplatesFolder]/gradle/wrapper/gradlew .
It gets the [rootTemplatesFolder] from the SDK(s) you specified in the "Project Structure" settings for default projects. In my case, I had several specified - both the new ones pointing to the sdk directory that's (thankfully) part of the Android Studio, and a few old ones I had somewhere else. I should not have included the old ones at all, but I'm a newb to this and the GUI let me do it. The NewProjectWizard was checking the tools area of that one first, which did not have that file, since the tools version with it was older than version 22.
I had to use dtruss to watch the system calls of Android Studio to see where it was looking for that file, at which point I could tell what my silly problem was.
I have a few more notes on this, including a screenshot of my particular misconfiguration, at http://www.nowherenearithaca.com/2013/08/solved-android-studio-and-your-android.html
Note: It seems you have to restart Android Studio for the "New Project Settings" here to take effect.
for ubuntu:
Open sdk manager from Android Studio or configuration.
make sure you download or update the latest release SDK and build tools.
Set the sdk location as (your android folder/sdk)
It'll download and install sdk
just Update sdk with sdk manager
it worked for me
