The import android.support cannot be resolved

For me they were appearing when i transferred code manually to another laptop. Just do

File>Invalidate Cache/Restart

click on 'Invalidate Cache and Restart' and your are done.


Another way to solve the issue:

If you are using the support library, you need to add the appcompat lib to the project. This link shows how to add the support lib to your project.

Assuming you have added the support lib earlier but you are getting the mentioned issue, you can follow the steps below to fix that.

  1. Right click on the project and navigate to Build Path > Configure Build Path.

  2. On the left side of the window, select Android. You will see something like this:

  1. You can notice that no library is referenced at the moment. Now click on the Add button shown at the bottom-right side. You will see a pop up window as shown below.

enter image description here

  1. Select the appcompat lib and press OK. (Note: The lib will be shown if you have added them as mentioned earlier). Now you will see the following window:

enter image description here

  1. Press OK. That's it. The lib is now added to your project (notice the red mark) and the errors relating inclusion of support lib must be gone.

andorid-support-v4.jar is an external jar file that you have to import into your project.

This is how you do it in Android Studio:

Go to File -> Project Structure enter image description here

Go to "Dependencies" Tab -> Click on the Plus sign -> Go to "Library dependency" enter image description here

Select the support library "support-v4 (com.android.support:support-v4:23.0.1)" enter image description here

Now to go your "build.gradle" file in your app and make sure the android support library has been added to your dependencies. Alternatively, you could've also just typed compile 'com.android.support:support-v4:23.0.1' directly into your dependencies{} instead of doing it through the GUI.

Rebuild your project and now everything should work. enter image description here


Please follow these Steps:

For Eclipse:

  • Go to your Project's Properties
  • Navigate to the Java Build Path
  • Then go to the Libraries tab. There click the Add External JARs Button on the Right pane.
  • Select the android-support-v4.jar file, usually the path for the Jar file is :
    YOUR_DRIVE\android-sdks\extras\android\support\v4\android-support-v4.jar
  • After adding android-support-v4.jar Library, navigate to the Order and Export tab and put check mark on the android-support-v4 Library file.
  • After doing the above, Clean the Project and Build it.
  • Problem Solved.

For Android Studio:

Short Version:

  • Add the following line to your build.gradle file:
    implementation 'com.android.support:support-v4:YOUR_TARGET_VERSION'

Long Version:

  • Go to File -> Project Structure

  • Go to "Dependencies" Tab -> Click on the Plus sign -> Go to "Library dependency"

  • Select the support library "support-v4 (com.android.support:support-v4:YOUR_TARGET_VERSION)"

  • Navigate to your "build.gradle" inside your App Directory and double check if your desired Android Support Library has been added to your dependencies.

  • Rebuild your project and now everything should work.
