Referring the Frida tutorial.
public class MainActivity extends AppCompatActivity {
static {
System.loadLibrary("native-lib");
}
public native int Jniint();
In the tutorial Frida is used to intercept the call to the JNI method Jniint().
Activity.Jniint.implementation = function () {
// console.log is used to report information back to us
console.log("Inside Jniint now...");
// return this number of our choice
return 80085
};
I know Xposed can be used to hook Java methods and not native code, but is it also allowed to intercept calls to native methods (using findAndHookMethod) like Frida so that it can block any actual native code from an app to be executed and just return dummy result ?
