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 predefined faceplate (or select a custom KML script folder with Android >= 5.0).
|
|
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.
|
|
But it works exactly like with Windows. If you can write in the ROM file,
|
|
it should save the content of port 2 in the ROM file with Android too.
|
|
To save the port 2 in the HP49/50 with Emu48 for Android:
|
|
* copy "real50g-lc.kml", "real50g-lc.png", "keyb4950.kmi", "rom.49g" in a FOLDER of your Android device,
|
|
* in the menu:
|
|
- touch "New..." to create a new device
|
|
- or touch "Change KML Script..." to change the current KML script and ROM location
|
|
* select "[Custom KML script...]"
|
|
* select the FOLDER
|
|
* pick the calculator (which should be "Eric's Real 50g (Large Cropped)")!
|
|
And because, the file "FOLDER/rom.49g" is not readonly anymore, you can save your port 2.
|
|
BUT for the moment, it is saved ONLY when you CLOSE (or change) the state file. Not when you end the application.
|
|
- To speed up printing, set the 'delay' to 0 in the calculator's print options.

|
|
|
|
- Autosave only works once a manual save has been done (William Hostman from comment).
|

|
|
- The timezone seems to be GMT (localtime_r not right?)!
|
|
- 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?).
|
|
- Add a separation between the pixels (Suggestion from Jaime Meza).

BUILD
|
|
|
|
Emu48 for Android is built with Android Studio 3.4 (2019).
|
|
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.
