I am trying to modify my code to include the latest nav drawer as seen in Google play stand. For this the first step is to add the app compact v7 to my project. I first updated my SDK and then imported the library project. It threw some errors, I gooogled and set the version to 21 in Project properties. The errors were resolved.
Now when I try to add this to my project by importing the library I get all sort of resource not found errors. I am clueless as only after adding the app compact v7 to my project as a lib I get these errors what can be possibly wrong here?
I am following steps exactly as defined here
Here is the screen shot without any errors on app compact v7:
Right click on project --> Go to properties --> Go to Android --> Set Project Build Target as Android 5.0 or 5.0.1 --> Apply......Hope this will solve your problem

When i go to :
File > Project Structure
I have the following 5 errors:
Library 'appcompat-v7-19.0.1' is not used
Library 'Gradle: 19.0.1' is not used
Library 'Gradle: support-v4-19.0.1' is not used
Library 'Gradle: 4.2.42' is not used
Library 'play-services-4.2.42' is not used
I can fix the problem with the icon on the right, add to dependencies and i add to the selected module, it works but if i exit Android Studio and i run it again, the errors appears again.
Those errors are spurious and you can ignore them; that they appear at all is bug https://code.google.com/p/android/issues/detail?id=60958. Having said that, unless you're running a very old version of Android Studio, they shouldn't be appearing.
I have been on this problem for a couple hours. After downloading a repository from github, the only error in any .xml file is:
No resource found that matches the given name '#style/Theme.AppCompat.Light'
The code is very straightforward, but there is not one straightforward answer I have found, on how to alleviate the error.
here is the code (in file res/values/styles.xml):
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light">
<!-- API 14 theme customizations can go here. -->
</style>
The project is located at: https://github.com/erikswed/InstaChatX
I am on Windows, using Eclipse Kepler
What are the steps for that? where is AppCompat located?
Download the support library here:
http://developer.android.com/tools/support-library/setup.html
If you are using Eclipse:
Go to the tabs at the top and select ( Windows -> Android SDK Manager ). Under the 'extras' section, check 'Android Support Library' and check it for installation.
After that, the AppCompat library can be found at:
android-sdk/extras/android/support/v7/appcompat
You need to reference this AppCompat library in your Android project.
Import the library into Eclipse.
Right click on your Android project.
Select properties.
Click 'add...' at the bottom to add a library.
Select the support library
Clean and rebuild your project.
If you are looking for the solution in Android Studio :
Right click on your app
Open Module Settings
Select Dependencies tab
Click on green + symbol which is on the right side
Select Library Dependency
Choose appcompat-v7 from list
The steps described above do work, however I've encountered this problem on IntelliJ IDEA and have found that I'm having these problems with existing projects and the only solution is to remove the 'appcompat' module (not the library) and re-import it.
Below are the steps you can try it out to resolve the issue: -
Provide reference of AppCompat Library into your project.
If option 1 doesn't solve the issue then you can try to change the style.xml file to below code.
parent="android:Theme.Holo.Light"
instead.
parent="android:Theme.AppCompat.Light"
But option 2 will require minimum sdk version 14.
Hope this will help !

I have a project target to API Level 10 and i want to implement the new ActionBar support library.
After follow all the instrutions in the Support Library Setup, when adding the library to my project I came across with dozens of error messages like this:
android-support-v7-appcompat\res\values-v14\styles_base.xml:24: error: Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Holo.....
OK, i know that they are many answers to this question, but, after trying all the more obvious, i still could not solve the error.
I kept searching and found the cause, which is not so obvious, at least for newbies like me.
My intent is provide a full answer to help all those who are like me and do not master all the secrets of the Android development.
This is what you have to do for use the ActionBar support library correctly.
Follow the instructions in the Support Library Setup - Adding libraries with resources.
One thing that can bring some doubt is add the library to your aplicattion project:
(1) In the Project Explorer, right-click your project and select Properties.
(2) At the left pane select Android.
(3) At th bottom of the right pane click Add
(4) Select the library project android-support-v7-appcompat and click OK.
Click OK to close the properties window.
If you not get any of the errors I mentioned it´s all done.
However if you are like me, you dont´t followed the advice of Android team that suggests you always compile your source using the latest SDK, you get the error.
The error ocurrs because my Project Build Target was Android 2.3.3 and need to be at lest 3.0.
It was not immediately clear to me because of the fact that I'm specifically developing for Android 2.3.3 and I'm using support libraries.
OK, I hope this helps.
You should add that support library to your project. To add:
Right click on project, then go to :
properties > Java Build Path > Libraries
here Add External JARs...
add android-support-v7-appcompat.jar (path/to/sdk/extras\android\support\v7\appcompat\libs)
Additionally you also have to copy that jar to libs folder of your project, if it is not there automatically.
and you should use the #style/Theme.AppCompat theme for your application for support-v7 to be working
also keep one thing in mind you should change min sdk version to 11 if you want to support("android:windowActionBar")property in your project.
Why am I having such a hard time getting into the swing of Android development? I've been developing in various languages over the years and, for some reason, just can't seem to get beyond that "jeez-i-still-feel-a-total-noob" stage with Android.
So I'm trying to add an Action Bar to my Android 2.3.3 project. No problem, right? The Android developers website has a nice and clear article explaining exactly how to do it. Of course it involves adding the appcompat v7 support library. No problem, even this is documented step-by-step on this page. But, as with just about every such exercise in Android, I find that you can do exactly what the page tells you to do, it still won't work without significant amount of Googling to fix the errors that you encounter afterwards.
So I've followed the steps under "Using Eclipse" in the section "Adding libraries with resources" in the above link. The first error I get is Unable to resolve target 'android-16'. No problem, this one I could figure out for myself but I'm curious, is there anything in the documents I've been following that would have suggested to me that I need Android 4.1.2 (API16) installed? Did I just read right over it or should I have known by myself that, to do what I'm trying to do, I would need API16?
Never mind, at least I can fix that but then I get a new problem. As soon as I add the android-support-v7-compat library to my project and click the OK button, the console output lights up with errors, the first one being:
C:...\android-support-v7-appcompat\res\values-v14\styles_base.xml:24:
error: Error retrieving parent for item: No resource found that
matches the given name 'android:Widget.Holo.ActionBar'.
and the other 60 odd errors are similar but for different given names.
I would really appreciate if anyone could help me out here. Obviously I'd like to know how to solve this particular problem but if anyone could give me some tips on how to get past this very frustrating stage of learning this new development environment, I would be ever so thankful. What is it that I should have done differently not to run into these kinds of errors, other than following the instructions on the Android Developers website step by step?
OK, I guess I should post an answer as I've eventually managed to solve my own problem.
It turns out I have to use a build target of Android 4.2.2, regardless of the fact that I'm specifically developing for Android 2.3.3 - I mean, that's why I'm using support libraries after all. I imagine it might be possible that some other lower target (but higher than 2.3.3) would still work I just used the highest one I have installed and it solved the problem.
How I was supposed to know this from following the step-by-step instructions on the Android Developers website is a mystery to me. The reason I decided to try changing the targetSdkVersion was because of the final section in the page referenced in the question. It reads "If you are increasing the backward compatibility of your existing application to an earlier version of the Android API with the Support Library, make sure to update your application's manifest." Now I'm not increasing the backward compatibility of my existing application. I'm changing an existing application that targets 2.3.3 to be able to include an Action Bar (seems more like "forward compatibility"). I tried upgrading the targekSdkVersion though as I was out of ideas and lo and behold, it worked.
Don't know if it helps you at all, but I've been struggling with a similar issue for several hours and finally managed to resolve it. In my case, inside my own project's styles.xml file, I was referencing the AppCompat style in the wrong way in the parent attribute.
I was using:
<style name="AppBaseTheme" parent="android:Theme.AppCompat">
where I should have used:
<style name="AppBaseTheme" parent="#style/Theme.AppCompat">
My mistake was in the reference to the theme.
I found that setting the Android target to 2.3.3 for the library project android-support-v7-appcompat solves this issue. You don't need to set your project's target higher, but the library's target lower.
You have pinpointed the all important document and the relevant section "adding libraries with resources":
http://developer.android.com/tools/support-library/setup.html
The error suggests that your project is not able to find these resources. Please double check the following :
You have checked "is library" on the library project
You have exported the jars IN THE LIBRARY PROJECT as described in that section
You have added the library project as a reference to your app project
You have added the android-support-v4.jar to your libs folder in your app project
If this is all definitely correct, check eclipse for any error messages - is it the library project or the app project that lights up like the proverbial Christmas Tree ?
First of all check if you have done all the described steps as explained on the developers site. Then, for the errors :
Unable to resolve target 'android-16'
Make sure that you have installed API16, this errors occurs if you have mentioned your targetsdk to 16 in your Manifest while the sdk for API16 is not installed. You can either install the API or edit the targetApi of your project to the minimum required version, for the support library you are using I think API 11 is the minimum required android version.
android:Widget.Holo.ActionBar
This error should also be fixed once the targetsdk is fixed in your project. Since to use Holo.ActionBar you'l need to target your project to minimum supported api level ie. 11 or higher.
I met similar problems. Using API 18, ADT.
To solve the "Unable to resolve target 'android-16' problem", I remove the import lib project and repeat what the tutorial says.
Then I found I couldn't really "add" the library to my project. (The instruction "In the Library pane, click Add." there is not that detail.
1. In your project -> properties -> Java build path -> Libraries -> Add Library... -> Android Classpath Container -> Select the lib project
2. In your project -> properties -> Android -> add... -> choose the lib -> apply
cheers
Here is how I avoided the error, " Unable to resolve target 'android-16'", when adding v7.
First, I followed the instructions for adding support libraries with resources in eclipse. Following step 4, I clicked Finish. That's when I saw the error message, android-support-v7-appcompat] Unable to resolve target 'android-16'.
Second, I read this post. I also opened the download manager, but did not need anything updated. In order to make sure that I followed the steps exactly as correctly as I could, I deleted the android-support-v7-appcompat project and started over.
This second time I didn't check any different boxes, after all. But, I also got no errors at step 4. Who can say why?
Thanks, Dewald, you expressed in this question the same frustration I have. Is experience the only way out?
If some of your resource xml files cannot find their respective AppCompat references, make sure you also add the support libraries to your project properties. You do this by:
1.) right clicking on your project in the project
2.) Select properties. (Bottom of the menu)
3.) click Android on the left hand side menu of the new pop up window
4.) In the libraries section, click the "add button"
5.) Select the respective libraries. (If none show up, check to see if they are already displayed in the "libraries" window of the pop up menu. If there is a red x by the desired library, try and resolve that issue first.)
6.) Once there is a green checkmark next to the desired libraries, make sure the "Is Library" option in the libraries section IS NOT selected.
7.) Click apply.
8.) Close the pop up menu.
If this doesn't work, let me know and I can help you out. I spent three hours on the problem so I know pretty much all the possible things that can go wrong with the set up.
Go to Project -> uncheck Build Automatically
Go to Project -> Clean... , clean both the library project and your app project
Export your app as a signed APK while Build Automatically is still disabled
Hi I am a newbie to android and I am trying to run the Sliding Menu Example but i am getting so much errors
I have downloaded the package from here:
http://github.com/jfeinstein10/SlidingMenu/
and setup the actionbarsherlock
Also followed the instructions listed over here: http://boroniatechnologies.com/installing-slidingmenu-android-library-and-example/
and i am getting the following errors:
I am using Eclipse 22.0.0 and recent version of Android SDK
try this...
add actionbarsherlock library to slidingmenu library
in your project libraries, use only sliding menu library, not
actionbarsherlock.
delete the android support library in libs
folder in slidingmenu library, and in libs folder in your project
and clean all projects, and try it.
If you have updated SDK means,
select project->right click->go to properties->order and export>select Android Private Libraries. Click Ok.
Clean the project and run it.
The usual suspect for such errors is the minSdk/targetSdkVersion of your Android project. Try minSdkVersion of 7 and targetSdkVersion 17 (latest as of now). That is, your AndroidManifest.xml should be having this line
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="17" />
And also, from project properties, set Android 4.2 (latest as of now) as the target. Project properties -> Android -> target:4.2
That should solve it. But, if you are still getting errors (on account of different versions of SlidingMenu), experiment with higher minSdkVersion.
