Android Apifier

HTTP and API networking library for Android with Cronet and OkHttp.

Features

• Cronet Integration: Multi-provider Cronet support (GMS → Native → Java fallback)
• HTTP/3 & QUIC: Modern protocol support for improved performance
• Configurable Retry: Built-in exponential backoff and retry logic
• Progress Tracking: Download/upload progress monitoring
• Secure Cookies: Encrypted cookie storage with customizable backend
• Connection Optimization: Mobile-optimized connection pooling and timeouts
• DSL Configuration: Kotlin DSL for clean, type-safe configuration

Installation

Add JitPack repository:

repositories {
maven { url 'https://jitpack.io' }
}

Add dependency:

dependencies {
implementation 'com.github.Androidacy:android-apifier:2.0.0'
}

Documentation

API documentation is available at javadoc.jitpack.io

Usage

val client =ApifierClient(context) {
cronet {
enableQuic =true
enableHttp2 =true
quicHint("api.example.com")
cacheDirectory = context.cacheDir.resolve("cronet")
}
timeouts {
connect =5.seconds
read =60.seconds
}
retry {
maxAttempts =3
retryOn5xx =true
}
cookieStorage(MyCookieStorage())
header("User-Agent", "MyApp/1.0")
dynamicHeader("Authorization") { getAuthToken() }
}
client.get("https://api.example.com/data", object:Callback {
overridefunonResponse(call:Call, response:Response) {
// Handle response
}
overridefunonFailure(call:Call, e:IOException) {
// Handle error
}
})

Cookie Storage

Implement CookieStorage interface:

classMyCookieStorage : CookieStorage {
overridefungetStringSet(key:String, defaultValue:Set<String>?) =
encryptedPrefs.getStringSet(key, defaultValue)
overridefunputStringSet(key:String, value:Set<String>) =
encryptedPrefs.edit { putStringSet(key, value) }
overridefunremove(key:String) =
encryptedPrefs.edit { remove(key) }
}

Progress Tracking

client.download(url, object:ProgressListener {
overridefunupdate(bytesRead:Long, contentLength:Long, done:Boolean) {
val progress = (bytesRead *100/ contentLength).toInt()
updateProgressBar(progress)
}
}, callback)

Security

TLS trust for API traffic runs through Cronet, which honors your app's Network Security Configuration. Configure trust anchors, certificate pinning, and cleartext policy there — the library does not override them:

<network-security-config>
<domain-config>
<domainincludeSubdomains="true">api.example.com</domain>
<pin-set>
<pindigest="SHA-256">base64EncodedPin==</pin>
</pin-set>
</domain-config>
</network-security-config>

Cookies are stored encrypted with a hardware-backed AES-GCM key, and DoH bootstrap connections are validated against system CAs only.

Requirements

• Android API 26+
• Kotlin 2.2+
• OkHttp 5.3+
