Emacs vs HexViewer
Side-by-side comparison of two open source alternatives
Emacs
GNU Emacs is an extensible, customizable, free/libre text editor — and more. At its core GNU Emacs is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. The features of GNU Emacs include: * Content-aware editing modes, including syntax coloring, for many file types; * Complete built-in documentation, including a tutorial for new users; * Full Unicode support for nearly all human scripts; * Highly customizable, using Emacs Lisp code or a graphical interface; * A wide range of functionality beyond text editing, including a project planner, mail and news reader, debugger interface, calendar, IRC client, and more; * A packaging system for downloading and installing extensions. Notes regarding Android support: * The on-screen keyboard is automatically invoked when a non read-only buffer is tapped, and the user option `touch-screen-display-keyboard' arranges for it always to be displayed. * `modifier-bar-mode' may be enabled to display a panel of modifier keys beside the tool bar. * Permissions are not granted by default, but must be explicitly enabled in system settings menu. * External storage permissions may be granted by observing the instructions in the banner that is displayed on the splash screen if they are denied. * Answers to other questions probably exist in the Android appendix to the bundled Emacs manual.

HexViewer
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.
