Battery Intent API Reference

Overview

This document describes functionality of battery intent APIs of Zebra devices. It is intended for Android developers familiar with Android intent mechanisms and applies to devices running Android 4.4 KitKat and later.

On Zebra devices, battery information can be retrieved using Android battery intents just as on consumer devices. On devices equipped with Zebra Power Precision or Power Precision Plus batteries, additional information can be retrieved as indicated in the Battery Extras table shown below.

Programming Interface

Function Prototype


mIntent_Receiver = new Intent_Receiver();
mIntentFilter = new IntentFilter();
mIntentFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(mIntent_Receiver,mIntentFilter);

Parameters

Please refer to the Android Battery Manager API.

Return Values

In addition to the battery information Android returns by default, some Zebra batteries return information for the following additional parameters:

bkvoltage
mfd
serialnumber
partnumber
ratedcapacity
battery_decommission
battery_usage_numb
health_percentage
present_capacity
base_cumulative_charge
total_cumulative_charge
present_charge
time_to_empty
time_to_full
seconds_since_first_use
battery_percent_decommission_threshold
battery_usage_decommission_threshold

See Battery Extras table above for usage info.

Example


public void onReceive(Context context, Intent intent) {
    if (BATTERY_STATE_CHANGED_INTENT.equals(intent.getAction())) {

        int bkvoltage = intent.getExtras().getInt("bkvoltage");
        String mfd = intent.getExtras().getString("mfd");
        String serialnumber = intent.getExtras().getString("serialnumber");
        String partnumber = intent.getExtras().getString("partnumber");
        int ratedcapacity = intent.getExtras().getInt("ratedcapacity");
        int cycle = intent.getExtras().getInt("cycle");

    }
}
