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.suppo

Answer 1

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

Answer 2

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.

So the error "package android.support.v4.util does not exist" simply means you have to copy the above jar file to your libs subdirectory and recompile.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

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 :)
