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.
