Get battery informations from android device
<p>I try to get some informations about the android device battery like actual current, voltage,...
I succeed to get voltage, level, ... but unfortunately I have a phone which run with API 16 and the parameter BatteryManager.BATTERY_PROPERTY_CURRENT_NOW doesn't exist with this API because it appears with API 21.</p>

<p>So, how to get the current information and battery capacity info for example for this device ?</p>

<p>Thanks in advance.</p>
