How to End Incoming Call in Monodroid?

Question

Java developers had used reflection for reaching endcall method of ITelephony until 2.3, in order to end incoming call, but this method has been prevented later, so it is nonaccessible via c# in monodroid neither.

Is there any way to do it in 'Mono For Android'?

Java开发人员使用了反射

它是相同的 - 只是不同的:而不是Java反射,你使用JNIEnv.

假设您想要移植这个基于Java反射的代码:

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());
}

如果你恰到好处地斜视,你可以得到这个(完全未经测试!)C#代码:

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);
