Java developers had used reflection
It's the-same-just-different: instead of Java reflection, you'd use JNIEnv.
Assume you want to port this Java reflection-based code:
try {
TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class c = Class.forName(manager.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
ITelephony telephony = (ITelephony)m.invoke(manager);
telephony.endCall();
} catch(Exception e){
Log.d("",e.getMessage());
}
If you squint just right, you can get this (entirely untested!) C# code:
var manager = (TelephonyManager) this.GetSystemService (Context.TelephonyService);
IntPtr TelephonyManager_getITelephony = JNIEnv.GetMethodID (
manager.Class.Handle,
"getITelephony",
"()Lcom/android/internal/telephony/ITelephony;");
IntPtr telephony = JNIEnv.CallObjectMethod (manager.Handle, TelephonyManager_getITelephony);
IntPtr ITelephony_class = JNIEnv.GetObjectClass (telephony);
IntPtr ITelephony_endCall = JNIEnv.GetMethodID (
ITelephony_class,
"endCall",
"()Z");
JNIEnv.CallBooleanMethod (telephony, ITelephony_endCall);
JNIEnv.DeleteLocalRef (telephony);
JNIEnv.DeleteLocalRef (ITelephony_class);
