AndroidHiddenApiBypass

Bypass restrictions on non-SDK interfaces.

Why AndroidHiddenApiBypass?

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: unsafe, art structs and setHiddenApiExemptions are stable APIs.

How it works (Chinese)

Integration

Gradle:

repositories {
    mavenCentral()
}
dependencies {
    implementation 'org.lsposed.hiddenapibypass:hiddenapibypass:4.3'
}

Usage

Invoke a restricted method:

HiddenApiBypass.invoke(ApplicationInfo.class, new ApplicationInfo(), "usesNonSdkApi"/*, args*/)

Invoke restricted constructor:

Object instance = HiddenApiBypass.newInstance(Class.forName("android.app.IActivityManager$Default")/*, args*/);

Get all methods including restricted ones from a class:

var allMethods = HiddenApiBypass.getDeclaredMethods(ApplicationInfo.class);
((Method).stream(allMethods).filter(e -> e.getName().equals("usesNonSdkApi")).findFirst().get()).invoke(new ApplicationInfo());

Get all non-static fields including restricted ones from a class:

var allInstanceFields = HiddenApiBypass.getInstanceFields(ApplicationInfo.class);
((Method).stream(allInstanceFields).filter(e -> e.getName().equals("longVersionCode")).findFirst().get()).get(new ApplicationInfo());

Get all static fields including restricted ones from a class:

var allStaticFields = HiddenApiBypass.getStaticFields(ApplicationInfo.class);
((Method).stream(allStaticFields).filter(e -> e.getName().equals("HIDDEN_API_ENFORCEMENT_DEFAULT")).findFirst().get()).get(null);

Get specific class method or class constructor

var ctor = HiddenApiBypass.getDeclaredConstructor(ClipDrawable.class /*, args */);
var method = HiddenApiBypass.getDeclaredMethod(ApplicationInfo.class, "getHiddenApiEnforcementPolicy" /*, args */);

Add a class to exemption list:

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:

HiddenApiBypass.addHiddenApiExemptions("");
