As Google strongly restricts the use of SMS permissions for applications in the Play-Store, S2MSP provides an API for third party applications to send and receive SMS to specific phone numbers via a secure SMS proxy.S2MSP acts like a local firewall for SMS communication.Each application that wants to send/receive SMS to a phone number can register itself on S2MSP. S2MSP asks the user for permission, whether the requesting application is allowed to send/receive SMS from and to the requested phone numbers or not.All SMS exchanged with third party applications are strongly encrypted.S2SMP itself requires SMS permissions (SEND_SMS and RECEIVE_SMS) from the Android system and will request these permissions upon startup. S2MSP does not need any other permissions. This ensures the integrity and security of S2MSP.The API to integrate a third party application with S2MSP is available in Maven-Central.

Scans SAF (Storage Access Framework) paths for audio files and builds a database to be used by Unpopular Music Player or Opus 1 Music Player. Contrary to the Android service it knows about composers, works, movements, conductors etc. Application Field: * The SAF scanner can access USB memory devices, like USB sticks via OTG adapter, in Android 6, 7 and 8. Note that Android 9 and 10 natively allow (read) file access to USB memory, just like to SD cards. * The SAF scanner can extract album art on SD cards and USB memory devices, this is currently not possible with the classical scanner, because without SAF it is limited to read-only access. * The SAF scanner can access SMB or SFTP servers, if the respective document provider is installed. * The SAF scanner even deals with non-seekable files by reading them completely into memory before further processing. Features: * Can be run manually whenever audio files have been added, removed or changed. * Auto scan (incremental) or complete scan (rebuild) selectable. * Various audio file types (mp3, mp4, flac, ogg, ...). * Multi CD albums: sub-subdirectories "CD1", "CD2", ..., with common folder image. * Common and non-common text tags. * Composer and grouping (work, movements). * Proprietary Apple iTunes tags for classical music. * Extracting of embedded images if none already exists. * Downscaling of both extracted and existing album images. * Original images can be kept as backup, if desired. * Maximum image size is configurable. * Creates a standard SQLite database in /ClassicalMusicDb that can be accessed from PC or other apps.

The "AppCleaner" tool finds apps with expendable files. 📦 Manage all of your apps Get a comprehensive list of all apps installed on your device. Enabled, disabled, user or system app: no app can hide from you. The "AppControl" tool is an app manager that lets you search, sort and control your apps. 📊 What is using all your space Storage management can be complex with apps, media, system, and other files across device storage, SD cards, and USB devices. "StorageAnalyzer" is a file manager that displays how space is used on your device, simplifying your storage management. 📷 Find duplicate data Duplicate downloads, photos sent through social media or just similar pictures of the same scene: Over time copies can accumulate.

This app does not use the AccessibilityService API to collect information. SD Maid 2/SE is a File Manager & Cleaner App.

Rescan storage media like SD cards for changes. SD Scanner uses a method compatible with 4.4 KitKat and 5.0 Lollipop. In Android 4.4 KitKat, the method used by most older programs to rescan a storage medium no longer works. Instead, an interface must be used that only allows one file to be specified at a time. This app works by determining what files/folders might need to be scanned again, and then by calling the correct API on each file/folder. SD Scanner can be used with Tasker by using the "Send Intent" action listed under "System." Use the following settings, leaving the ones I don't list at the default: * Action: android.intent.action.RUN * Package: com.gmail.jerickson314.sdscanner * Class: com.gmail.jerickson314.sdscanner.MainActivity * Target: Activity

This app can display the data produced and managed by Song Database if the file is accessible via URL (web address). It cannot be used for anything else, so if you don't use Song Database, this app isn't meant for you! You can view the song lyrics, any available translation and the guitar chords (if available). Translation and chords can be disabled in the settings. The app keeps a local version of the data until it can fetch an update (after a timeout which is three days by default) so you can use it offline as well. If you are the administrator of your Song Database installation and don't want to upload the file containing the songs every time you modify it, you could set up a synchronisation solution like Nextcloud and use the "share link" functionality - the resulting link has to be used in the app. In case you don't want to force all users to enter the link manually: The app can be configured by scanning a QR code. For more information on that, see the homepage.
