    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


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

    2. Visit

    3. Please contact me ( if you have any issues, problems, comments, questions, or suggestions regarding this app.

    4. Permissions: READ_EXTERNAL_STORAGE - used for the file browser (Select App) to allow you to navigate to and select a file to execute a function (calc checksum, etc.) against.

    Thanks and enjoy!

    This is the only app I've found that makes checking *.md5 files a rapid process. Since that is by far my most common use of checksums, it's an easy decision to give this app five stars.
