我正在尝试制作一个Android模块，并在模块内获得WiFi SSID

但是,

getApplicationContext（）
in

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService (Context.WIFI_SERVICE);
WifiInfo info = wifiManager.getConnectionInfo ();
String ssid  = info.getSSID();
函数在模块内部不起作用

如何在Android模块中获取WiFi SSID字符串？

您需要在Android模块中创建一个方法来初始化
上下文。然后从您的
主android应用程序调用该方法，初始化模块上下文的最佳位置是应用程序#onCreate
