A Glossary
(1) SDK: a set of software development kit (Software Development Kit) application software development tools
(2) JDK: Java development tools, the main provider of basic libraries, Java compiler, runtime JVM (Java Virtual Machine), debugger, etc.
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
(3) JRE: Java Runtime Environment (Java Runtime Environment) Java Runtime Environment, when a part of the JDK
(4) Android SDK: Software Development Kit Andrews, on the basis of added additional JDK class library android.jar, Android provides a virtual machine DVM and ART
(5) JNI: Java Native Interface JNI is the Java Native call a specification language, you can make Java and C / C ++ models interact through JNI
(6) NDK: The official explanation Native Develp Kit as follows: Android NDK is a set that allows you to use native code languages (such as C and C ++) implementation tool set some of the features, in short, Android besides Java can be used to achieve, part can be done with C ++, NDK does not depend on Dalvik Java virtual machine
NDK is mainly the Native language is compiled into a dynamic link library (.dll files, .so file, .jnilib)
(7) .NET: Microsoft .NET Framework, .NET technology framework consisting of specific implementation in the Windows system, in short the equivalent of Java jdk, that is the most basic development package, the most basic framework
(8) Mono: .net framework is an open source, cross-platform, not Microsoft's products, it is also composed of mono mono compiler and run-time
(9) IL: .NET code into the machine language into an intermediate language, the code that is compiled after .NET does not generate direct machine language, but will become Mr. IL, similar to assembly code
Two main components Android program
(. 1) the AndroidManifest.xml: Unity path corresponding to Assets / Plugins / the AndroidManifest.xml the Android manifest file containing the application name, icon, package name, the four assembly modules, permissions
(6) libs: correspondence Unity path Assets / Plugins / Android stored inside a jar and class libraries written in Java aar
Unity call three Android
(1) AndroidJavaClass is a general representation of instances of java.lang.Class Unity
(2) AndroidJavaObject are generic examples of java.lang.Object representation Unity
example:
（3）Activity和UnityPlayerActivity
https://www.jianshu.com/p/476087b4c087
UnityPlayerActivity is the default unity Android package Activity
（4）application
application can be inherited, the following is an example
Then referenced in the androidmanifest
(5) android code calls a function of Unity
UnityPlayer.UnitySendMessage(string gameObject, string runtimeScript, string arg);
Four examples of mobile MM
application
package com.xx.Racing;
import android.app.Application;
import android.content.Context;
import com.secneo.sdkp.DexHelper;
public class MMApplication
extends Application
{
protected void attachBaseContext(Context ctx) {
super.attachBaseContext(ctx);
DexHelper.install(this, "mmbilling.3.1.8.jar.protected.jar");
}
}
AndroidforUnity to the library unity call
package com.mm.payforunity;
import android.content.Context;
import mm.purchasesdk.Purchase;
public class PayForUnity
{
private static final String APPID = "300009265921";
private static final String APPKEY = "065DF5E770AE73C7ECDE5EE7FA174999";
private static IAPListener listener;
public static void InitSDK(Context context, String gameObject, String runtimeScript) {
try {
Purchase.getInstance().setAppInfo("300009265921", "065DF5E770AE73C7ECDE5EE7FA174999");
}
catch (Exception e1) {
e1.printStackTrace();
}
listener = new IAPListener(context, gameObject, runtimeScript);
try {
Purchase.getInstance().init(context, listener);
}
catch (Exception e) {
e.printStackTrace();
}
}
public static void doPay(Context context, String paycode) {
try {
Purchase.getInstance().order(context, paycode, 1, listener);
}
catch (Exception e1) {
e1.printStackTrace();
return;
}
}
}
