Hexadecimal viewer for Android
About this app
This application offers the following features :
- Opening all files without a corresponding Android application (1). - Display of the file in hexadecimal (or plain text) with the possibility to modify the content (in hexadecimal only). - Saving the file on the smartphone/tablet (2). - Search option in the open file (hexadecimal and plain text modes).
(1) At first, the file can only be saved via "save as" and due to Android permissions reasons, the only way to make it appear in the list of recent files is to reopen it. (2) Due to file permissions, after a "save as", the list of recent files cannot be updated with the new file location.
Caution: Opening files that are too large seriously degrades application performance and can suddenly stop the application on low-resource devices.
**WARNING:** This application cannot open files larger than ~20 MB on recent smartphones and less for older smartphones.
**WARNING:** Searching within the plain text view may become excessively slow when handling large files.
A special thanks to @OmlineEditor for her patience and help, without her this application would not be at this level.

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be fr.ralala.hexviewer is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.59.7 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall HexViewer first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of HexViewer, and a listing is removed when the evidence for it stops holding up.
