KNet
Android network client based on Cronet. This library let you easily use HTTP/3 and QUIC protocol in your Android projects. You can see more about QUIC here - mobile or product or backend
Order:

Gradle
You can try this library using Gradle:
dependencies {
implementation 'com.vk.knet:core:1.0'
implementation 'com.vk.knet:cronet:1.0'
implementation 'com.vk.knet:okcronet:1.0'
}Initialization
Short version:
val cronet = CronetKnetEngine.Build(App.context) {
client {
enableQuic(
CronetQuic(hints = listOf(Host("drive.google.com", 443)))
)
}
}
val knetCronet = Knet.Build(cronet)Full version:
CronetLogger.global(
object : CronetHttpLogger {
override fun error(vararg obj: Any) {
Log.e("Logos", obj.toList().toString())
}
override fun debug(type: CronetHttpLogger.DebugType, vararg obj: Any) {
Log.d("[${type.name}]", obj.toList().toString())
}
override fun info(vararg obj: Any) {
Log.i("Logos", obj.toList().toString())
}
}
)
private val cronet = CronetKnetEngine.Build(App.context) {
client {
setCache(CronetCache.Disk(App.context.filesDir, 1024 * 1024 * 10))
enableHttp2(true)
enableQuic(
CronetQuic(
hints = listOf(
Host("drive.google.com", 443)
),
)
)
useBrotli(true)
isClearBrokenHosts(true)

addMetricListener { metric: HttpMetrics, _, _ ->
Metrics.addMetric(metric)
}
}
addInterceptor { p ->
try {
p.proceed(p.request)
} catch (e: Exception) {
try {
println("[KNet] [RETRY ${if (e is ConnectException) e.message else e.localizedMessage}]")
p.proceed(p.request)
} catch (e: Exception) {
e.printStackTrace()
throw e
}
}
}
}
val knetCronet = Knet.Build(cronet) {
bufferPool(ByteArrayPool.DEFAULT)
}OkHTTP
If you're now using OkHttp, you can simply wrap KNet into OkHttp Interceptor... Easy, right?
val knetCronet = Knet.Build(cronet)
val okhttpInterceptor = KnetToOkHttpInterceptor(knetCronet)
val builder = OkHttpClient.Builder()
builder.addInterceptor(okhttpInterceptor)
val client = builder.build()Comming Soon
