Starting from Android 9 (API level 28), the platform enforces restrictions on non-SDK interface usage. These restrictions apply when apps attempt to access non-SDK interfaces through reflection or JNI.
These measures were implemented to enhance stability by reducing unexpected crashes and minimizing emergency updates for developers.
For more details, see Google's official documentation: Improving Stability by Reducing Usage of non-SDK Interfaces.

try { val clazz = Class.forName("dalvik.system.VMRuntime") val method = clazz.getDeclaredMethod("setHiddenApiExemptions", Array<String>::class.java) Toast.makeText(context, "API access succeeded: $method", Toast.LENGTH_SHORT).show() } catch (e: Throwable) { Toast.makeText(context, "API access failed: ${e.message}", Toast.LENGTH_SHORT).show() }

• Zero Code Modification - Works with existing codebase without any changes
• Automatic Exemption Handling - Transparently manages hidden API access restrictions
• Lightweight Integration - Single initialization call for seamless operation
• Cross-Version Support - Compatible with Android 9+ (API 28 and higher)

Add dependency in your app's build.gradle:

dependencies { implementation 'io.github.chanjlee:hiddenapi:1.1.0' }

Initialize once in your Application class:

class MyApp : Application() { override fun onCreate() { super.onCreate() HiddenApiCompat.compat(this) } }

The library implements the following mechanisms:

• Automatic Signature Bypass - Utilizes Android's hidden API exemption protocol
• Reflection Optimization - Smart handling of reflection requirements
• Runtime Safety - Maintains original app behavior while enabling privileged access
