Unity calls a collection of various methods of Android

Easy way to call Android

public class SDKInterfaceAndroid
{

    private AndroidJavaObject jo;
    private static ASCSDKInterface _instance;
    public static ASCSDKInterface Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = new SDKInterfaceDefault();
            }
            return _instance;
        }
    }
    public SDKInterfaceAndroid()
    {
        using (AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
        {
            jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
        }
    }

    public T SDKCall<T>(string method, params object[] param)
    {
        try
        {
            return jo.Call<T>(method, param);
        }
        catch (Exception e)
        {
            Debug.LogError(e);
        }
        return default(T);
    }

    public void SDKCall(string method, params object[] param)
    {
        try
        {
            jo.Call(method, param);
        }
        catch (Exception e)
        {
            Debug.LogError(e);
        }
    }
}

Using the above code directly, you can easily call Android methods with or without return values.
For example :

//调用无返回值方法
SDKInterfaceAndroid.Instance.SDKCall("你的安卓方法名");
//调用返回值为bool类型
bool isOn=SDKInterfaceAndroid.Instance.SDKCall<bool>("getbool");
//调用返回值为int类型
int Num=SDKInterfaceAndroid.Instance.SDKCall<int>("getInt");
//调用方法并传入参数
SDKInterfaceAndroid.Instance.SDKCall("安卓方法名","要传入的字符类型参数");
