Google said that
“As an open-source platform, Android is built upon the collaboration of the open-source community,” a Google spokesperson told VentureBeat. “In our upcoming release of Android, we plan to move Android’s Java language libraries to an OpenJDK-based approach, creating a common code base for developers to build apps and services. Google has long worked with and contributed to the OpenJDK community, and we look forward to making even more contributions to the OpenJDK project in the future.”
And they imported OpenJDK files as a part of the project. OpenJDK is under a GPL license.
What parts of android will not have to be under the GPL? What about android apps?
