<component name="libraryTable">
<library name="Gradle: com.android.support:drawerlayout-28.0.0-alpha1">
<CLASSES>
<root url="file://$USER_HOME$/.gradle/caches/transforms-1/files-1.1/drawerlayout-28.0.0-alpha1.aar/f65a939895672f396c5831b3b24607b0/res" />
<root url="jar://$USER_HOME$/.gradle/caches/transforms-1/files-1.1/drawerlayout-28.0.0-alpha1.aar/f65a939895672f396c5831b3b24607b0/jars/classes.jar!/" />
</CLASSES>
<JAVADOC />
<SOURCES>
<root url="jar://$USER_HOME$/.gradle/caches/modules-2/files-2.1/com.android.support/drawerlayout/28.0.0-alpha
