How to use

Push the xinjector and the so to be injected into /data/local/tmp on the android device.

$ adb push libs/arm64-v8a/xinjector /data/local/tmp
$ adb push libnative-lib.so /data/local/tmp

Execute the xinjector file:

$ adb shell
$ su
$ cd /data/local/tmp
$ ./xinjector package_name /data/local/tmp/libnative-lib.so entry_point_function_name entry_point_parameters

package_name --> the package name of the app that you want to inject into.
/data/local/tmp/libnative-lib.so --> injected so file path.
entry_point_function_name --> the function to be called in the injected so, this is alternative.
entry_point_parameters --> the function parameter to be passed in, this is alternative too.
