1月21日的Reveal Hidden Media应用程序分析

This application searches for all images and videos that are not showing in the gallery. These, sometimes legitimate files, can be unnecessary and take up valuable space on your device. These are for example: - Ads - Files sent with WhatsApp (and therefore duplicated) - etc ... Images and videos can be masked with basically three techniques: 1. .nomedia files placed in directories to tell Android not to index files there. 2. Hidden directories or files by giving them a name starting with a period. 3. Files disguised by giving them an extension that is not that of an image or a video. This application is able to detect all these cases. The results are presented in two lists (images and videos) which can be filtered. A long press allows you to select the files to be able to delete them (be careful not to delete the files required by the applications). This application is guaranteed without collection of personal data! AUTHORIZATIONS REQUIRED In order to access all files on the device, the app requests the permissions below: • MANAGE_EXTERNAL_STORAGE - Allows an application wide access to storage. • WRITE_EXTERNAL_STORAGE - Allows an application to write to storage.
