package android.support.v4.util does not exist

Question

Since the last update for android support libraries, I am having issues with importing LruCache. Eclipse, and now even android studio, keep saying that package android.support.v4.util does not exist.

I am using actionbarsherlock and it has included android support v4 and shows no errors. My application was working fine before this last SDK update. What has changed? How do I fix this?

Here is the error that shows:

java: /Users/amit/App/src/com/app/EMCache.java:5: package android.support.v4.util does not exist
java: /Users/amit/App/src/com/app/EMCache.java:9: cannot find symbol
symbol  : class LruCache
location: class com.app.EMCache
java: /Users/amit/App/src/com/app/EMCache.java:20: cannot find symbol
symbol  : class LruCache
location: class com.app.EMCache

This might be related to [ClassNotFoundException after ADT update](https://stackoverflow.com/questions/16610190/classnotfoundexception-after-adt-update/16610247#16610247) or [Eclipse giving error, missing R.java file after recent update](https://stackoverflow.com/questions/16608524/eclipse-giving-error-missing-r-java-file-after-recent-update/16608570#16608570), which were solutions to common problems in the rev. 22 update. — Krauxe, May 18 '13 at 06:45

In my case, the solution was eventually found as documented here:

Make sure you have downloaded the Android Support Library using the SDK Manager.
Create a libs/ directory in the root of your application project.
Copy the JAR file from your Android SDK installation directory (e.g., <sdk>/extras/android/support/v4/android-support-v4.jar) into your application's project libs/ directory.

I got here without checking this answer, as evidenced by my ability to upvote it. Hopefully I will find it more easily next time I get this error, ie when moving IDE's. – John Jan 15 '15 at 22:13

After trying tweaking build.gradle different ways, ended up with solution found here: https://github.com/kmagiera/react-native-gesture-handler/issues/394#issuecomment-508358572

in short - you can solve it with jetifier:

npm install --save-dev jetifier npx jetify

From the package docs:

If you use React Native modules with native Java code that isn't converted to AndroidX, and your app is AndroidX, you probably need this.

If you're using Gradle, I had to also add this line to the dependencies section of my inner build.gradle, the file where you specify your minSdkVersion and targetSdkVersion:

dependencies {
  compile "com.android.support:support-v4:19.0.+"
}

I believe the '19' is supposed to be whatever your compileSdkVersion. If I'm wrong, it will tell you what it's supposed to be.

You will probably have to update the version to the version in your environment. eg, for me the version was: "com.android.support:support-v4:23.0.+" – steven smith Feb 19 '17 at 22:10

For those importing the support libraries using gradle like this:

// compat libraries
compile 'com.android.support:support-v4:23.2.0' // v4
compile 'com.android.support:appcompat-v7:23.2.0' // v7
compile 'com.android.support:support-v13:23.2.0' //v13

Remember to remove this all*.exclude module: 'support-v4' from configurations

configurations {
    //all*.exclude module: 'support-v4'
}

...might have been a dummy mistake from my part though :)

Thank you. Updating the gradle file to use the latest support library ( 23.3.0 as of 2016-04-14) has solved my problem. It was using 23.2.1, and had this problem after an SDK update. – Hong Apr 14 '16 at 21:08

In my case I was porting an Android Googlemaps app API1 to API2, and after many hours I realized I was not adding

C:\Program Files\..(your_path_)..
  ..\adt-bundle-windows-x86_64\sdk\extras\android\support\v4

to External Libraries..

Hope this helps

Step-1: Open Project in AndroidStudio3.3 or above, wait until loading of the project completes.

Step-2: Right click 'app' -> Refactor -> Migrate to AnroidX

Step-3: Review the changes in AndroidStudio console below and click 'Do Refactor'

The issue will be fixed.

I replace 'import androidx.core.util.LruCache;' with 'import android.util.LruCache;', and then no error – Venus May 25 '21 at 09:12

craned's answer:

dependencies {
    compile "com.android.support:support-v4:19.0.+"
}

worked for me. But (in my case at least) the '19' should match the compileSdkVersion

Go to your Android SDK's directory and:

jar tvf ./extras/android/support/v13/android-support-v13.jar |grep v4.*util

And within this jar file you can see one of the classes (under v4/util) you have used in your applications.

In my case the problem was referencing the jar from sdk installation folder, copying the jar to project's libs folder adding to build path actually resolved the issue.

In my case with Android Studio, this error appeared in the middle of a working project and refused to disappear despite much fooling around. I finally forced a Gradle Sync operation by adding a single space character to a Gradle file. The Gradle Sync fixed it instantly.

add dependency

dependencies { compile 'com.android.support:support-v4:+'}

Change Build Tool

 dependencies {  classpath 'com.android.tools.build:gradle:2.3.0'}

Worked for me.
