Hi All
In my Android app, I need to call a non static java method from C/C++.
But i get a blunt crash when i do it using
GetMethodID/CallVoidMethod()1 methods.
I have done like this:
1. Register the method using GetMethodID() as follows (mine is a cpp file):
jmethodID xyz = (env)->GetMethodID( cls, "showxyz", "()V");
2. And I call this method as follows:
env->CallVoidMethod(cls, xyz);
3. In java, my showxyz() is defined this way(this basically enables a
button which was disabled)
void showxyz()
{
findViewById(R.id.btnPass).setEnabled(true);
}
And this crashes.
But I have been using this method of calling Java funcs from C using a
set of GetStaticMethodID/CallStaticVoidMethod()(for nonstatic
methods) and that works always.
But in this case, I have to call a non-static method and i get a crash.
Can anybody please tel me where I am going wrong. I know this is a
basic JNI knowledge. But I am left high and dry. Please do advise.
thanks
Latha
