Error: "the Following Classes Could Not Be Found: - Android.support.v7.widget.gridlayout" After Upgrading Android Sdk Tools

Solution 1:

Apparently, you do not have the Android library project containing GridLayout referenced from your project, perhaps because the old reference is now broken.

Solution 2:

Edit you project's (and library project's too) .classpath file like this:

<?xml version="1.0" encoding="UTF-8"?><classpath><classpathentryexported="true"kind="con"path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/><classpathentryexported="true"kind="con"path="com.android.ide.eclipse.adt.DEPENDENCIES"/><classpathentryexported="true"kind="con"path="com.android.ide.eclipse.adt.LIBRARIES"/><classpathentrykind="src"path="src"/><classpathentrykind="src"path="gen"/><classpathentrykind="output"path="bin/classes"/></classpath>

Solution 3:

It probably updated your default support v4 lib and now the on in your projetc/lib folder is probably a different version from the one inside v7.

Delete the support v4 jar file in your project/lib folder.

You can have it there and work with the support v7 lib, but v7 already has a v4 lib and they must have the same version to work.

Remove the v4 jar file in your lib folder, then add the v7.

Solution 4:

Important Change

You should replace android.support.v7.widget.Space with android.support.v4.widget.Space
