Unity and Android Coordination work considerations

Original address: http://blog.csdn.net/u012085988/article/details/17436191

1. Unity Tune Android function

[CSharp]View Plaincopy

1. Androidjavaclass JC = new Androidjavaclass ("Com.unity3d.player.UnityPlayer");
2. Androidjavaobject activity = JC.  Getstatic<androidjavaobject> ("currentactivity");
3. Activity. Call ("func")

Activity is the current Activity,call function prototype call<re-type> (FName, args). Within the angle brackets is the return value, the first argument is the function name, the second is the argument

Note: The number of arguments

1, the number is the same, and more than 1. Executable

2. Unity brings in fewer parameters than Android defines. Error: Nosuchmethoderror

3. Unity brings in more parameters than the number of Android-defined parameters. Error: Nosuchmethoderror

Note: When the Android side has overloaded functions

According to the parameter table, find the corresponding function

Note: The JNI is based on similar (ljava/lang/string; Ljava/lang/string;i) v This format to match the function. So the number of parameters, parameter type must be one by one corresponding

2. Android Callback Unity function

[CSharp]View Plaincopy

1. Unityplayer.unitysendmessage ("Androidmanager", "Androidcallbackunlockgame", " " ");

The first argument is Gameobject, the second argument is the function name, and the third is the argument (string)

Note: The names are case-sensitive. and the parameter type, the number of parameters should be corresponding to each.

Note: The third argument cannot be null, to pass an empty string, you can write "", but you cannot write null. Otherwise it will crash!

3. UI processing in Android

[CSharp]View Plaincopy

1. Runonuithread (new Runnable () {
2. public Void Run () {
3. Text (msg);
4. }
5. });
