[Solved] Android appcompat v7 error
Being new to Android developent I followed the simplest of tutorials, built a new android project, accepting all default settings (built it for kitkat). To my dismay I have an un-planned project –
appcompat_v7, along with the errors:
The container ‘Android Dependencies’ references non existing library
and twice the following
The project cannot be built until build path errors are resolved
Is there a quick way to fix these?
Is this a sign of how difficult, and bugged with unpleasant surprises learning Android is going to be?
(Hope it will not be similar to learning IOS 6 years ago…)
appcompat_v7 library is added by default to an Android project. You will most likely need it for any demo projects you start making.
To correctly add this library, follow these steps:
For Android Studio:
2. In your
build.gradle file, include the following
3. Perform a Gradle sync with the
Sync Project button.
The trick is, you need to clean & build the
appcompat_v7 project. Go to
Project -> select Clean -> select the project.
After doing this, if the project does not get built automatically, right click on the project in the package explorer and select
Build Project. Now the
.jar file will be generated in the project’s
bin folder. After that, clean & build all projects that reference
Now the library should be correctly referenced by all projects that need it.
Note also that:
- You must have the latest versions of SDK Tools / Build Tools
/ Platform Tools. If you try this and it doesn’t work, then go to
the Android SDK Manager and make sure you have the latest versions of
the required tools.
- In case your project only requires API level 14 (Ice Cream Sandwich)
& above, select API level 14 for “minimum required SDK” in the
project wizard when you create a new project. Now the appcompat_v7
library will not be required for this project, and the application
will use the native ActionBar class which is present in AOSP builds
from ICS onwards.
The accepted answer worked for me but only after I’d installed the latest Java JDK (which was a solution to the problem detailed here Android – “Parsing Data for android-21 failed”)
Need to update your SDK manager
click ur sdk manager icon in the ecilipse then update android support Repository in the extras
go to File->import->existing project
abt bundle->sdk->extra->android->support->v7 to workspace
after import v7 to workspace go to lib folder choose both jar and right click and choose build to workspace then again right click v7 project go to java build path choose the checkbox and click apply and ok..
if u have updated sdk then follow this steps
Right click ur project then go to
property->choose java build path
click Add External jar
Browse to ur adt bundle go to ur workspace choose the folder
android-support-v7-appcompat -> lib -> appcompat_v7.jar
Appcompat_7 error solved!
Hi, im a complete beginner, i solved my problem by go to SDK manager update/install all the new android sdk build tools (as im not sure which is which i should update/install so i update/install all the build tools. after updated/installed all the new build tools i closed my eclipse and relaunch the eclipse again. if you see any error again? go to the top bar click PROJECT and choose CLEAN. and run your application again and i think it will work fine..
it worked for me when i changed project build tarjet to API 21 for the android_support_v7_appcompact project
I had the same problem and I tried all of mentionded above advices and much more from, but no one helped me to solve my issue. My solution was creating a progect with minimum required SDK API 14: Android 4.0 (IceCreamSandwich). Doing this way Eclipse will not create appcompat_v7 project.
Also I found another, better, solution:
- Go to Android SDK Manager and install Android 5.0.1 (API 21) or newer. If you don’t use the emulator you can install only SDK Platform and Google APIs;
- Go to appcompat_v7 -> Properties -> Android and check Android 5.0.1 in the Project Build Target;
- Then go to Java Build Path -> Order and Export and check Android 5.0.1;
- Do the same procedure for your project.
Strange fix but this worked for me ( My minimum SDK for my project is 10 – can’t use 14)
- Right-click on the “appcompat_v7” project and go to
-> Properties -> Android.
- Your target build should already be set at the latest build (in my case Android 5.0.1). Click any other android package (apart from its current target) and click “Apply”. Click “Ok” to close the box.
- Re-open the Properties box by the same method but this time check the latest build (in my case Android 5.0.1) as the Project Build Target. Click “Apply”, then “Ok” to close the box.
- Clean the appcompat_v7 project. You’ll probably need to clean/build all other projects that reference this library.
This solved it for me.
I was having with same Issue and fed up but finally I got the answer . I resolved this by Copy appcompat library E:adt-bundle-windows-x86_64-20140702sdkextrasandroidsupportv7appcompat and paste appcompat Library in the the Project which I want to Import . I close the Eclipse and reopen. But One thing I want to consider before these stuff I updated Android Support Repository and Android Support Library as well.
I solved it by downloading the file manually somewhere on the internet (be careful) and putting it into the needed
appcompat_v7in folder before creating a new Android project. After that, also my
R.java file was generated successfully.
Honestly, no other way seemed to fix it. Could not obtain the file via the SDK manager.
