Android Hidden Api Bypass

Bypass restrictions on non-SDK interfaces.

Why HiddenApiBypass?

• Pure Java: no native code used.
• Reliable: does not rely on specific behaviors, so it will not be blocked like meta-reflection or dexfile.
• Stable: does not rely on internal ART structures on Android 10+. Unsafe and setHiddenApiExemptions are stable APIs.

And LSPass?

• Fast: no I/O, initializing faster than HiddenApiBypass.
• Safe: no Unsafe.
• Unreliable: can be blocked as easily as meta-reflection.

How it works

HiddenApiBypass: Unsafe

LSPass: Property.of()

Integration

Gradle:

repositories {
    mavenCentral()
}
dependencies {
    implementation 'org.lsposed.hiddenapibypass:hiddenapibypass:+'
}

Usage

This library has two variants of bypassing, they have the same API. When initializing, LSPass is faster than HiddenApiBypass, but LSPass maybe blocked in future Android releases. Replace HiddenApiBypass with LSPass if you do not want to use Unsafe.

1. Invoke a restricted method: java HiddenApiBypass.invoke(ApplicationInfo.class, new ApplicationInfo(), "usesNonSdkApi"/*, args*/)
2. Invoke restricted constructor: java Object instance = HiddenApiBypass.newInstance(Class.forName("android.app.IActivityManager$Default")/*, args*/);
3. Get all methods including restricted ones from a class: java var allMethods = HiddenApiBypass.getDeclaredMethods(ApplicationInfo.class); ((Method).stream(allMethods).filter(e -> e.getName().equals("usesNonSdkApi")).findFirst().get()).invoke(new ApplicationInfo());
4. Get all non-static fields including restricted ones from a class: java var allInstanceFields = HiddenApiBypass.getInstanceFields(ApplicationInfo.class); ((Method).stream(allInstanceFields).filter(e -> e.getName().equals("longVersionCode")).findFirst().get()).get(new ApplicationInfo());
5. Get all static fields including restricted ones from a class: java var allStaticFields = HiddenApiBypass.getStaticFields(ApplicationInfo.class); ((Method).stream(allStaticFields).filter(e -> e.getName().equals("HIDDEN_API_ENFORCEMENT_DEFAULT")).findFirst().get()).get(null);
6. Get specific class method or class constructor java var ctor = HiddenApiBypass.getDeclaredConstructor(ClipDrawable.class /*, args */); var method = HiddenApiBypass.getDeclaredMethod(ApplicationInfo.class, "getHiddenApiEnforcementPolicy" /*, args */);
7. Add a class to exemption list: java HiddenApiBypass.addHiddenApiExemptions( "Landroid/content/pm/ApplicationInfo;", // one specific class "Ldalvik/system" // all classes in packages dalvik.system "Lx" // all classes whose full name is started with x ); if you are going to add all classes to exemption list, just leave an empty prefix: java HiddenApiBypass.addHiddenApiExemptions("");
