+# CorePatch
+
+```
+A Module For Xposed Framework
+Disable signature verification For Android
+ ```
+![Android CI](https://github.com/coderstory/CorePatch/workflows/Android%20CI/badge.svg)  ![GitHub release (latest by date)](https://img.shields.io/github/v/release/coderstory/CorePatch)  ![CRAN/METACRAN](https://img.shields.io/cran/l/devtools)
+
+### Description
+```
+branch master -> support  android 4.4-7.x
+Android8.x ->  maybe you need find the commit what change version name to 2.1,then compile by you self
+branch Q -> support android 9.0-10.0
+branch main -> support android 10-15
+```
+
+## Features
+```
+ allows to downgrade application, suppresses [INSTALL_FAILED_VERSION_DOWNGRADE]
+
+ allows to directly install apps after modifing APK file [ignore invalid digest error etc..]
+
+ allows overlay install apps with inconsistent signatures
+```
+
+### History
+You can download history version from https://soft.shouji.com.cn/down/32512.html
