These are artifacts published in the JitPack repository. These are not functional and only provides stubbed implementations. All methods in all classes throw a runtime exception. Because an Android app runs on a device, it will never use these libraries for execution, but the API compatibility allows an app to be compiled as if it was the real library.
That would be useful if you are trying to build a java part of your Android code.
Add it in your root build.gradle at the end of repositories:
ext {
androidArtifactsVersion = "5278588d80-2017-07-24"
}
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
For the latest androidArtifactsVersion
value see the builds section: https://github.com/Scarabei/AndroidArtifacts/releases
dependencies {
compile "com.github.Scarabei.AndroidArtifacts:%put-dependency-name-here%:$androidArtifactsVersion"
}
Now you can develop/compile your java library aganst the Android API without Android framework. Also you can publish it on a Maven repo.
This part is on you. Should look something like:
dependencies {
compile "com.your.java-lib"
}
That would be necessary if you fail to compile your Android app with errors like:
Error:Execution failed for task :app:transformClassesWithDexForDebug.
Error:Error converting bytecode to dex
or similar.
Edit your gradle settings:
android {
defaultConfig {
minSdkVersion ...
targetSdkVersion ...
...
multiDexEnabled = true
}
dexOptions {
javaMaxHeapSize "4g" //specify the heap size for the dex process
}
See the link for details: https://developer.android.com/studio/build/multidex.html
android {
...
configurations {
all*.exclude group: "com.github.Scarabei.AndroidArtifacts", module: "put-dependency-name-here"
}
}
By this we tell AbdroidStudio to discard the stub jar to use the real Flutter API on a device.
