Android Broadcast Receivers no funciona
¡ Atención !
Según Android Developers:
https://developer.android.com/codelabs/android-training-broadcast-receivers
Starting from Android 8.0 (API level 26 and higher), you can't use static receivers to receive most Android system broadcasts, with some exceptions. So for this task, you use dynamic receivers:
Los static receivers son los que se especifican en el archivo androidmanifest.xml.
