在 Delphi 中实现 addDefaultNetworkActiveListener

你需要构建这样的东西：

uses
  Androidapi.JNIBridge, Androidapi.JNI.Net;

type
  TNetworkActiveListener = class(TJavaLocal, JConnectivityManager_OnNetworkActiveListener)
  public
    procedure onNetworkActive; cdecl;
  end;

然后声明一个变量：

  FNetworkActiveListener: TNetworkActiveListener;

创建它并添加它：

  FNetworkActiveListener := TNetworkActiveListener.Create;
  // Use the code from the other answer for GetConnectivityManager
  GetConnectivityManager.addDefaultNetworkActiveListener(FNetworkActiveListener);
