Android monitors Battery status

Recently, a GPS-related project has been developed, because it involves the use of GPS. As we all know, GPS consumes a lot of power, so I want to know how to know the current power, when the power usage reaches a lower limit, the user is reminded in time to disable GPS as needed to save power for urgent calls. Later, the user checked the information and looked at the API and finally found a method, how to monitor the power, how to obtain the current power according to the power change, and manage the Mobile Phone Based on other statuses to achieve optimal management.

Below isCode:

Code

  Private  Broadcastreceiver mbatinforeceiver  =     New  Broadcastreceiver (){
  Int Intlevel  =     0  ;
  Int  Intscale  =     0  ;

  Public     Void  Onreceive (context, intent ){
String action  = Intent. getaction ();
  /*  
* If the captured action is action_battery_changed, run onbatteryinforeceiver ()
  */  
  If  (Intent. action_battery_changed.equals (Action )){
Intlevel  =  Intent. getintextra (  "  Level  "  ,  0 );
Intscale  =  Intent. getintextra (  "  Scale  "  ,  100  );

  //  Batteries  
  Log. D (  "  Battery v  "  , ""     +  Intent. getintextra (  "  Voltage  "  ,  0  ));
  //  Battery Temperature  
  Log. D (  "  Battery t  " ,  ""     +  Intent. getintextra (  "  Temperature  "  ,  0  ));
Batteryv  =     "  Current voltage:  "    +  Intent. getintextra (  "  Voltage  "  ,  0  );
Batteryt  =     "  Current temperature:  "     +  Intent. getintextra (  " Temperature  "  ,  0  );

  Switch  (Intent. getintextra (  "  Status  "  ,
Batterymanager. battery_status_unknown )){
  Case  Batterymanager. battery_status_charging:
Batterystatus  =    "  Charging status  "  ;

}
  Switch (Intent. getintextra (  "  Plugged  "  ,

  Case  Batterymanager. battery_plugged_ac:

  Break  ;
 Case  Batterymanager. battery_plugged_usb:

  Break  ;
}

  Switch  (Intent. getintextra (  "  Health  " ,

  Case  Batterymanager. battery_health_unknown:

  Break  ;
  Case  Batterymanager. battery_health_good:

  Break  ;
  Case  Batterymanager. battery_health_dead:

  Break  ;

  Break  ;

}
}

This information is used to listen to the broadcast. It is determined based on the broadcast information. If it is a broadcast with a change in power, it is used to update the data for analysis!
