# Android Hidden Api Bypass
[](https://github.com/LSPosed/AndroidHiddenApiBypass/actions/workflows/android.yml)
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](https://lovesykun.cn/archives/android-hidden-api-bypass.html)
LSPass: [Property.of()](https://github.com/michalbednarski/LeakValue?tab=readme-ov-file#putting-it-all-together)
## Integration
Gradle:
```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*/)
```
1. Invoke restricted constructor:
```java
Object instance = HiddenApiBypass.newInstance(Class.forName("android.app.IActivityManager$Default")/*, args*/);
```
1. 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());
```
1. 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());
```
1. 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);
```
1. Get specific class method or class constructor
```java
var ctor = HiddenApiBypass.getDeclaredConstructor(ClipDrawable.class /*, args */);
var method = HiddenApiBypass.getDeclaredMethod(ApplicationInfo.class, "getHiddenApiEnforcementPolicy" /*, args */);
```
1. 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("");
```
