用于 Unity 的 Android 插件

Question

嗨，我正在尝试为 Unity 使用登录插件。 我将 java 文件放在 Unity 中，并自定义了 AndroidManifest 和 build.gradle。

构建成功，但是当我单击登录按钮时没有任何反应。

我认为这是关于上下文问题。 但是我是初学者，所以我不知道我该怎么做。 ：（ 请帮我！！！！！！！！

这是统一代码。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Login : MonoBehaviour
{
AndroidJavaClass unityClass;
AndroidJavaObject unityActivity;
AndroidJavaObject unityContext;
AndroidJavaClass plugin;

private void Awake() 
{

//Get Unity Context
unityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
unityActivity = unityClass.GetStatic<AndroidJavaObject>("currentActivity");
unityContext = unityActivity.Call<AndroidJavaObject>("getApplicationContext");

plugin = new AndroidJavaClass("com.company.example.javaPlugin");
}

public void NavLogin()
{
plugin.Call("CallAndroid", unityContext);
}
}

---

这是 java 代码。

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.content.Context;

import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;

public class javaPlugin extends UnityPlayerActivity {

private Context context;

@Override
protected void onCreate(Bundle savedInstanceState)
{
 Log.d("#####", "onCreate()");
super.onCreate(savedInstanceState);

}

public void CallAndroid(Context context)
{
this.context = context; 
Log.d("#####", "CallAndroid()");

Intent loginIntent = new Intent(this, naverLogin.class);
context.startActivity(loginIntent);
      
}


@Override
public void onBackPressed() {
Log.d("#####", "onBackPressed()");
//super.onBackPressed();
}
}

编辑 Java

package com.company.example;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.content.Context;

import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;

public class javaPlugin extends UnityPlayerActivity {

private Context context;
Activity activity;

@Override
protected void onCreate(Bundle savedInstanceState)
{
Log.d("#####", "onCreate()");
super.onCreate(savedInstanceState);
}

 public void CallAndroid(Activity activity)
{
 this.activity = activity; 
 Log.d("#####", "CallAndroid()");

 Intent loginIntent = new Intent(this, naverLogin.class);
 activity.startActivity(loginIntent);
          
}


@Override
public void onBackPressed() {
    Log.d("#####", "onBackPressed()");
    //super.onBackPressed();
}
}

编辑统一

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Login : MonoBehaviour
{
AndroidJavaClass unityClass;
AndroidJavaObject unityActivity;
//AndroidJavaObject unityContext;
AndroidJavaClass plugin;

public void Start() 
{
    //Get Unity Context
    unityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    unityActivity = unityClass.GetStatic<AndroidJavaObject>("currentActivity");
    //unityContext = unityActivity.Call<AndroidJavaObject>("getApplicationContext");
    plugin = new AndroidJavaClass("com.company.example.javaPlugin");
}

public void NavLogin()
{
    plugin.Call("CallAndroid", unityActivity);
}
}

我创建了一个演示项目来帮助您。

它有 C# class：

using UnityEngine;

public class Test : MonoBehaviour
{
    void Start()
    {
        var unityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        var unityActivity = unityClass.GetStatic<AndroidJavaObject>("currentActivity");
        var javaClass = new AndroidJavaClass("com.company.example.Test");
        javaClass.CallStatic("CallAndroid", unityActivity);
    }
}

Java class：

package com.company.example;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.content.Context;

public class Test {

    static Activity _activity;

    public static void CallAndroid(Activity activity)
    {
        _activity = activity;
        Log.d("#####", "CallAndroid() - Telemetry is fine.");

        //Continue doing what you need...
    }
}

请确保您像这样创建了 java class ：
