Google states that it aims to address the needs of the Android community, and has evidently began working on early device development for Android 11 based on client feedback, the existing situation during the coronavirus pandemic, and the other goals that come with that. In this case, delaying the release by one month seems to be a fair solution.
Google will launch a virtual conference starting with # Android 11: the Beta Launch Show. The tentative launch dates from june 1 to 3. At the beginning of June, the organization will host an online developer experience named # Android11: the Beta Launch Series. The latest beta launch date of June 3 is around a month later than originally expected, said Google’s Vice President.
