App force closes when plugged in after device reboot

I have a broadcast receiver that has the intent filter: ACTION_POWER_CONNECTED. The receiver is supposed to start a service. The receiver works great when the device has not been restarted, but once I restart the device and plug the device in, the app force closes. In my receiver I'm referencing another activity's static variable. Why does the app force close like that?

"dataSaved" is a SharedPreferences variable in MainActivity

if (MainActivity.dataSaved.getBoolean("User", false)) {
    Intent i = new Intent(context, BatteryService.class)
    context.startService(i);
}

You said the dataSaved is a static SharedPreference, it is not initialized, so getBoolean throws a NullPointerException. You initialized it when somewhere in the MainActivity but after restart no MainActivity to initialize it

Get the sharedprefernce in the reciever

SharedPreferences dataSaved = context.getSharedPreferences("prefs",  Context.MODE_PRIVATE);
 boolean isUser = dataSaved.getBoolean("User", false);
