# Keyman for Android & Keyman Engine for Android
|
|
|
|
## Prerequisites
|
|
See [build configuration](../docs/build/index.md) for details on how to configure your build environment.
|
|
|
|
## Keyman Minimum Android Requirements
|
|
Keyman for Android has a minSdkVersion of 21 for [Android 5.0 Lollipop](https://developer.android.com/about/versions/lollipop)
|
|
|
|
## Keyman for Android Development
|
|
Keyman for Android (formerly named KMAPro) can be built from a command line (preferred) or Android Studio.
|
|
|
|
Building Keyman Web is a precursor for compiling KMEA, so verify your system has all the [Minimum Web Compilation Requirements](../web/README.md#minimum-web-compilation-requirements)
|
|
|
|
### Crash Reporting
|
|
Keyman for Android uses [Sentry](https://sentry.io) for crash reporting at a server https://sentry.keyman.com. The analytics for Debug are associated with an App Bundle ID `com.tavultesoft.kmapro.debug`.
|
|
|
|
### Compiling From Command Line
|
|
1. Launch a command prompt and cd to the directory **keyman/android**
|
|
2. Run the top level build script `./build.sh -debug` which will:
|
|
* Compile KMEA (and its KMW dependency)
|
|
* Download default keyboard and dictionary resources as needed
|
|
* Compile KMAPro
|
|
* Note: to force an update to the latest keyboard and dictionary packages, use the `-download-resources` flag.
|
|
|
|
3. The APK will be found in **keyman/android/KMAPro/kMAPro/build/outputs/apk/debug/kMAPro-debug.apk**
|
|
|
|
### Compiling From Android Studio
|
|
1. Ensure that [Keyman Engine for Android](#how-to-build-keyman-engine-for-android) is built.
|
|
2. Launch Android Studio and import the Gradle project **keyman/android/KMAPro/build.gradle**
|
|
3. From the project view, *configure* anything that Gradle reports.
|
|
4. Create a run configuration for kMAPro
|
|
1. Select Run --> Edit Configurations...
|
|
2. Select Add New Configuration (+) --> Android App
|
|
3. Change Module to kMAPro
|
|
4. Name your run configuration kMAPro (or as desired)
|
|
5. Run your new configuration: Select Run --> Run 'kMAPro'
|
|
6. Select a physical device or create a new virtual device to match your target API version
|
|
For Ubuntu 18.04, you will need to add your user to the `kvm` group for permission accessing the emulator.
|
|
```
|
|
sudo apt install qemu-kvm
|
|
sudo adduser <username> kvm
|
|
```
|
|
|
|
### Running From Command Line
|
|
1. Launch a command prompt
|
|
2. Ensure that a physical device is connected or an emulator is running.
|
|
1. To list physical devices: `$ANDROID_HOME/platform-tools/adb.exe devices`
|
|
2. To list created emulator devices: `$ANDROID_HOME/tools/emulator.exe -list-avds`
|
|
3. [Create a new virtual device](https://developer.android.com/studio/run/managing-avds.html) if there are no
|
|
existing devices.
|
|
4. Start an emulator: `$ANDROID_HOME/tools/emulator.exe @nameofemulator`
|
|
3. Load the APK: `$ANDROID_HOME/platform-tools/adb.exe install -r path/to/apk.apk`
|
|
* If multiple devices are connected you may need `$ANDROID_HOME/platform-tools/adb.exe install -r -s SERIAL path/to/apk.apk`. Replace `SERIAL` with
|
|
the device serial number listed in step 2.
|
|
|
|
### Compiling the app's offline help
|
|
Keyman for Android help is maintained in the Markdown files in android/help/.
|
|
The script `build-help.sh` uses the `pandoc` tool to convert the Markdown files into html.
|
|
|
|
```bash
|
|
./build-help.sh htm
|
|
```
|
|
|
|
This script is automatically called when Keyman for Android is built.
|
|
|
|
### Sample Projects
|
|
|
|
There are two included sample projects that can be modified to test a keyboard.
|
|
|
|
**android/Samples/KMSample1** app runs a bare Keyman app for testing a keyboard.
|
|
|
|
**android/Samples/KMSample2** app provides prompts for setting KMSample2 as a system level keyboard.
|
|
Both sample apps include a default Tamil keyboard.
|
|
|
|
Building these projects follow the same steps as KMAPro:
|
|
|
|
1. Build KMEA
|
|
2. cd to the desired KMSample directory
|
|
3. `./build.sh`
|
|
4. Open Android Studio to run the app
|
|
|
|
### Tests: KeyboardHarness
|
|
|
|
**android/Tests/KeyboardHarness** app is a test harness for developers to troubleshoot keyboards.
|
|
|
|
1. Copy the keyboard js file and applicable ttf fonts to *android/Tests/KeyboardHarness/app/src/main/assets/*.
|
|
2. In Keyman Developer
|
|
* Open the `keyboardharness.kpj` project and add your keyboard files to the keyboard package.
|
|
* Build the keyboardharness.kmp keyboard package
|
|
3. Add the keyboard in *android/Tests/KeyboardHarness/app/src/main/java/com/keyman/android/tests/keyboardHarness/MainActivity.java*
|
|
4. cd to android/Tests/KeyboardHarness/
|
|
5. `./build.sh`
|
|
6. Open Android Studio to run the app
|
|
|

## How to Build Keyman Engine for Android
|
|
1. Open a terminal or Git Bash prompt and go to Keyman Engine for Android project folder (e.g. `cd ~/keyman/android/KMEA/`)
|
|
2. Run `./build.sh`
|
|
|
|
Keyman Engine for Android library (**keyman-engine.aar**) is now ready to be imported in any project.
|
|
|
|
## How to Use Keyman Engine for Android Library
|
|
|
|
1. Add **keyman-engine.aar** into **[Your project folder]/app/libs/** folder.
|
|
a. We recommend [downloading](https://keyman.com/downloads/#android-engine) the the latest stable release of Keyman Engine and extracting the .aar file.
|
|
b. If you choose to use your own build of the Keyman Engine, get the library from **android/Samples/KMSample1/app/libs/keyman-engine.aar**
|
|
2. Open your project in Android Studio.
|
|
3. Open **build.gradle** (Module: app) in "Gradle Scripts".
|
|
4. Check that the `android{}` object, includes the following:
|
|
```gradle
|
|
android {
|
|
compileSdkVersion 30
|
|
buildToolsVersion "30.0.2"
|
|
|
|
// Don't compress kmp files so they can be copied via AssetManager
|
|
aaptOptions {
|
|
noCompress "kmp"
|
|
}
|
|
compileOptions {
|
|
sourceCompatibility = JavaVersion.VERSION_1_8
|
|
targetCompatibility = JavaVersion.VERSION_1_8
|
|
}
|
|
```
|
|
5. After the `android {}` object, include the following:
|
|
````gradle
|
|
repositories {
|
|
flatDir {
|
|
dirs 'libs'
|
|
}
|
|
google()
|
|
mavenCentral()
|
|
}
|
|
|
|
dependencies {
|
|
implementation fileTree(dir: 'libs', include: ['*.jar'])
|
|
implementation 'androidx.appcompat:appcompat:1.3.0-rc01'
|
|
implementation 'com.google.android.material:material:1.3.0'
|
|
api (name:'keyman-engine', ext:'aar')
|
|
implementation 'io.sentry:sentry-android:4.3.0'
|
|
implementation 'androidx.preference:preference:1.1.1'
|
|
|
|
// Include this if you want to have QR Codes displayed on Keyboard Info
|
|
implementation ('com.github.kenglxn.QRGen:android:2.6.0') {
|
|
transitive = true
|
|
}
|
|
}
|
|
|
|
````
|
|
5. include `import com.tavultesoft.kmea.*;` to use Keyman Engine in a class.
