according to XDA Developers Report, Google releasedNew policyTo restrict the ability of the Android app to view other apps installed on the device. It is written in the developer plan policy, which will be implemented and updated on May 5, that access to the QUERY_ALL_PACKAGES permission will be restricted, that is, other installed apps on the device can be viewed on Android 11 or newer systems Ability.
According to the new policy, “Google Play treats the list of installed applications on the device (obtained from the user’s device) as personal and confidential information; unless the application requires information about the applications installed on the user’s device A wide range of browsing permissions can provide users with core functions or purposes. Otherwise, QUERY_ALL_PACKAGES permissions must not be used.”
So what app is suitable for the permitted purpose? Google lists device search capabilities, anti-virus applications, file management tools, and browsers. At the same time, if the developer believes that his “application only obtains less intrusive application browsing permissions, it will not be able to provide users with core functions that comply with the policy requirements, they must be able to fully explain the reason.”
This policy update is to prevent the device from being tracked by malicious programs and advertisers to what apps it contains. It also inherits Google’s 2018 to prevent the abuse of personal information by Android apps, which restricted viewing of communication records and SMS Content permissions. Later, Google said that it found that apps with access to relevant permissions in the Play Store have decreased by as much as 98%.
