Issue
Generating signed APK in Android Studio 2.3 fails with following error:
Error: The WIFI_SERVICE must be looked up on the Application context or memory will leak on devices < Android N. Try changing to .getApplicationContext() [WifiManagerLeak]
Resolution
As the error suggest it seems that WiFiManager must use Application Context (not Activity Context), otherwise a memory leak can occur. The error was triggered by following code:
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
To fix the issue I replaced the above line with:
WifiManager wifi = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
