DESCRIPTION
|
|
|
|
This project ports the Windows application Emu48 written in C to Android.
|
|
It uses the Android NDK. The former Emu48 source code 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:

|
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).
|
|
4. And the calculator should now be opened.
|
|
|
|
|
|
NOTES
|
|
|
|
- When using a custom KML script by selecting a folder, you must take care of the case sensitivity of its dependency files.

BUILD
|
|
|
|
Emu48 for Android is built with Android Studio 3.3 (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.
