八達通App將會監控Android裝置上所有App

Effective May 5, 2021, the permission will be limited to only those apps that are used for device search, as well as antivirus apps, file managers, and browsers. Other apps such as a dedicated banking app or a digital wallet app can qualify for this permission solely for security-based purposes.

Google also said it wouldn't allow apps to request the QUERY_ALL_PACKAGES permission when the "data is acquired for the purpose of sale" or the required task can be achieved by an alternative method.

"Apps that fail to meet policy requirements or do not submit a Declaration Form may be removed from Google Play," the company noted. "If you change how your app uses these restricted permissions, you must revise your declaration with updated and accurate information. Deceptive and non-declared uses of these permissions may result in a suspension of your app and/or termination of your developer account."
