Fail to find annotations.jar after updating to ADT 23

Question

So, seeing that the new Android L is out, I said I should give it a try. I installed the new ADT update from SDK tools and then from the updates. After Eclipse restart, I get the error that Android Dependencies failed to load because \android-sdk\tools\support\annotations.jar cannot be found.

I checked the folder and it does not have the file.

Well, I said to myself that maybe the ADT update didn't go well so seeing that the new eclipse 4.4 is out I thought I could do a fresh install. So downloaded eclipse 4.4, installed the ADT tools and android sdk... and I get the same error.

Any ideas on how to fix this ?

Answer 1

Uninstall/install Support library didn't help, so I did this:

Found ..\android-sdk\extras\android\support\annotations\android-support-annotations.jar and copied it to ..\android-sdk\tools\support\annotations.jar

The problem is gone since then. Doesn't look as incredibly awesome solution but at least now I can build my project in Eclipse.

A temporary solution from someone at google has been posted on the issue tracker: http://code.google.com/p/android/issues/detail?id=72419#c12

Please wait for an updated version within a day or two. Until then, your workaround is to do download one of:

• http://dl.google.com/android/android-sdk_r22.6.2-linux.tgz
• http://dl.google.com/android/android-sdk_r22.6.2-windows.zip
• http://dl.google.com/android/android-sdk_r22.6.2-macosx.zip

and copy over the following files:

• tools/hprof-conv
• tools/support/annotations.jar
• tools/proguard

Answer 3

Right click on your project --> project.properties --> target=android-19

Answer 4

Tomorrow I had the same problem after the update to ADT 23.

The problem is related to the annotations.

There are two libraries with annotations in the Android SDK:

android-sdk/extras/android/support/annotations/android-support-annotations.jar

this package contains:

• AnimRes
• AnimatorRes
• AnyRes
• ArrayRes
• AttrRes
• BoolRes
• ColorRes
• DimenRes
• DrawableRes
• FractionRes
• IdRes
• IntDef
• IntegerRes
• InterpolatorRes
• LayoutRes
• MenuRes
• NonNull
• Nullable
• PluralsRes
• RawRes
• StringDef
• StringRes
• StyleRes
• StyleableRes
• XmlRes

and

android-sdk/tools/support/annotations.jar

that...with the new ADT update, for some reason disappeared.

This package contains the two annotations (probably the most used :-)):

• SupportLint
• TargetApi

Without them, if your code (or dependencies use them) Eclipse will complain.

To fix this problem, we need the previous annotation.jar.

So I downloaded the file from the link suggested by @aarati:

http://central.maven.org/maven2/com/google/android/annotations/4.1.1.4/annotations-4.1.1.4.jar

Renamed it in annotation.jar and moved to: android-sdk/tools/support/

Restarting Eclipse everything will be fine.

Adding http://central.maven.org/maven2/com/google/android/annotations/4.1.1.4/annotations-4.1.1.4.jar as annotations.jar resolved my errors
