AFV File Verifier for Android™

Calculate MD5 & SHA1 checksums, verify signed files & Nandroid backups & more!

The AFV File Verifier for Android™ application is a tool for helping to verify & validate that files transferred to your Android™ device are whole and uncorrupted. Functions include:

* MD5 / SHA1 checksum calculation (also: SHA-224, SHA-256, SHA-384, SHA-512 algorithms)

* Validation of signed jar-type files (.jar, .apk, .zip); you can use this to verify a signed .zip file even if you don't know the MD5 checksum

* Nandroid backup directory MD5 verification

Excellent tool for root users (but does not require root).

How To Use:

* From the home screen, press the "Select File" button to enter the file-selector

* Top row (folder icon with the green up arrow) always displays the currently selected directory (touch this row to navigate UP one directory level)

* Back key can also be used to navigate UP one directory level (will return to main screen when back key is pressed at the root directory)

* Navigate to other subdirectories by touching a directory row (folder icon)

* Touch screen and drag up and down to scroll through all files and directories in currently selected directory

* Long-press on a file to view the available functions:

- Calc MD5 Checksum

- Calc SHA1 Checksum

- Verify Jar-type file

- Verify Nandroid Backup (long-press nandroid.md5 file to use this function)

- md5sum -c Type Check (operates on any .md5 file)

- Calc SHA224 Checksum

- Calc SHA256 Checksum

- Calc SHA384 Checksum

- Calc SHA512 Checksum

Notes:

1. Does not require root, but is useful for root users to validate ROMs, signed update.zip-type files, etc.
