android detect amperage from charger

I am trying to detect (if it is possible) the amperage coming from the charger/usb. is getting the intent extra - EXTRA_VOLTAGE will help me achieve that? sometimes the USB produces different amperage - 1000mA and sometimes less. How can I know the amperage?

Thanks!

Yes, ACTION_BATTERY_CHANGED is a sticky broadcast 

this.registerReceiver(this.batReceiver,     
    new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

private BroadcastReceiver batReceiver = new BroadcastReceiver(){

    @Override

    public void onReceive(Context arg0, Intent intent) {
    int voltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, 0);

    int source = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, 0);     

    }    
  };

It seems you want the charger source use EXTRA_PLUGGED 0 for battery, 1 for AC and 2 for USB

u have to use receiver and initilize like this in android manifestfile

 <receiver android:name=".reboot" android:enabled="true"
        android:exported="false" android:label="StartServiceAtBootReceiver">
        <intent-filter>
            <action android:name="android.intent.action.EXTRA_VOLTAGE" />
        </intent-filter>
    </receiver>

in reciver file

@Override
public void onReceive(Context context, Intent intent) {
    if("android.intent.action.EXTRA_VOLTAGE".equals(intent.getAction()))
    {
}
}
