本文主要完成两个功能，附上完整流程代码，以便后续查看

使用Unity5.6.3    JavaEclipse（Androidsdk同级目录）

ps:已测2017.3通过，需要增加定位权限

 

功能一：Unity应用实现开机自启动 获取电量WIFI等

1：创建项目 File--Android Application Project

2:导入class.jar     BuildPath-->Add External Archieves-->class.jar（使用Unity5.6.3测试）

D:\Program Files\Unity5.6.3\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes 

注意工程上方的Package Explorer！选错了就不会有Add External Archieves选项

增加WIFI权限（也可以在Unity里手动增加）

3：代码模块

MainActivity.java

package com.example.getinfo;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import com.unity3d.player.UnityPlayerActivity;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;


public class MainActivity extends UnityPlayerActivity {

	private static Context instance;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        instance = getApplication();
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    //获取手机当前电量、总电量（默认其实都是100）、当前状态（充电还是放电）
    //其余数据例如电压、电池温度用的较少
    public String MonitorBatteryState()
    {
        IntentFilter iFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
        Intent intent = instance.registerReceiver(null, iFilter);
        int rawLevel = intent.getIntExtra("level", 0);      //获得当前电量
        int scale = intent.getIntExtra("scale", 0);         //获得总电量
        int status = intent.getIntExtra("status", 0);       //电池充电状态
        int health = intent.getIntExtra("voltage", 0);      //电池健康状况
        int batteryV = intent.getIntExtra("voltage", 0);    //电池电压(mv)
        int temperature = intent.getIntExtra("temperature", 0); //电池温度(数值)
        double t = temperature / 10.0;  //电池摄氏温度，默认获取的非摄氏温度值，需做一下运算转换
        String targetStr = "";
        int level = -1;
        if(rawLevel > 0 && scale > 0)
        {
            level = (rawLevel * 100) / scale;
            targetStr = level + "|" + scale + "|" + status;
        }
        return targetStr;
    }

    //获取Wifi信号强度
    @SuppressWarnings("deprecation")
    private String ObtainWifiInfo()
    {
        String result = "";
        WifiManager wifiManager = (WifiManager)getApplication().getSystemService(WIFI_S
