DESCRIPTION This project ports the Windows application Emu48 written in C to Android. It uses the Android NDK. The former Emu48 source code (written by Sébastien Carlier and Christoph Giesselink) remains untouched because of a thin win32 emulation layer above Linux/NDK! This win32 layer will allow to easily update from the original Emu48 source code. It can open or save the exact same state files (state.e48/e49) than the original Windows application! Some KML files with theirs faceplates are embedded in the application but it is still possible to open a KML file and its dependencies by selecting a folder. The application does not request any permission (because it opens the files or the KML folders using the content:// scheme). The application is distributed with the same license under GPL and you can find the source code here: https://github.com/dgis/emu48android QUICK START 1. From the left side, slide your finger to open the menu. 2. Touch the "New..." menu item. 3. Select a default calculator (or with Android >= 5.0, "[Select a Custom KML script folder...]" where you have copied the KML scripts and ROM files (Android 11 cannot use the folder Download)). 4. And the calculator should now be opened. NOTES - The Help menu displays Emu48's original help HTML page and may not accurately reflect the behavior of this Android version. - When using a custom KML script by selecting a folder, you must take care of the case sensitivity of its dependency files. - Starting with the version 1.4, a RAM card generator for the port 2 of the HP48SX and HP48GX has been added. Like with the MKSHARED.EXE on Windows, you can generate the card in a file (i.e.: SHARED.BIN). And then, to use with the HP48SX or the HP48GX, you must select this generated file in the "Settings/Port2 File". - By default when you create a new HP49/50 with the embedded readonly file "rom.49g", everything that you store in port 2 is lost just because the file "rom.49g" is READONLY. Since version 2.0, it is now possible from the menu to manage the Flash ROM file (it will fully replaces the ROM). - To speed up printing, set the 'delay' to 0 in the calculator's print options. - The serial ports, wire or infrared (infrared limited to 2400 baud) can now be used through the USB port in mode OTG. It uses the library https://github.com/mik3y/usb-serial-for-android, which allows to plug most of the serial USB adapters (only tested with Prolific and Ch34x), without the need to be root. If it is not automatic, please, activate the OTG mode in your Android device, and then, you should be able to see it in the Emu48 settings. It is still experimental and I see some issues when sending characters from the emulator to a real HP48 or HP49 with the kermit protocol. For the moment, the communication has been artificially slowed down in this direction. If the adapter is unplugged then plugged back in, you may need to call OPENIO/CLOSEIO.

The Eric's Real scripts ("real*.kml" and "real*.bmp/png") are embedded in this application with the kind permission of Eric Rechlin. Portions of this source code (about the usb-serial) were originally created by Google Inc. in 2011-2013 and Mike Wakerly in 2013. TODO - Add a Cancel button to the HP48 memory card creator dialog. - Manage the HP 48 port 2 with the same kind of interface for the memory card. - The render pixels are very nice. A solution to obtain uniform pixel size could be a preset (a multiplier, auto) so the user could decide and upscale/downscale (Michael P). - Somehow LEFT (Shift on the keyboard) + 7 activates the DIVIDE-key (z-Key)..., but with the NUM-Key it can make it work without problems... I think it might have something to do with the "/" sign on the Shifted-7-key. - The clock seems not synchronized sometimes (Michael P). - Sometimes, the calculator seems to lag and finally freeze. - In Chrome OS, sometimes there is no OK button in the KML Script Compilation Result. - Add KML script loading dependencies fallback to the inner ROM (and may be KML include?). BUILD Emu48 for Android is built with Android Studio 2021.1.1 (2022). And to generate an installable APK file with a real Android device, it MUST be signed. Either use Android Studio: * In menu "Build" * Select "Generate Signed Bundle / APK..." * Select "APK", then "Next" * "Create new..." (or use an existing key store file) * Enter "Key store password", "Key alias" and "Key password", then "Next" * Select a "Destination folder:" * Select the "Build Variants:" "release" * Select the "Signature Versions:" "V1" (V1 only) * Finish Or in the command line, build the signed APK: * In the root folder, create a keystore.jks file with: ** keytool -genkey -keystore ./keystore.jks -keyalg RSA -validity 9125 -alias key0 ** keytool -genkeypair -v -keystore ./keystore.jks -keyalg RSA -validity 9125 -alias key0 * create the file ./keystore.properties , with the following properties: storeFile=../keystore.jks storePassword=myPassword keyAlias=key0 keyPassword=myPassword * gradlew build * The APK should be in the folder app/build/outputs/apk/release Then, you should be able to use this fresh APK file with an Android device.
