Get current milliAmps of battery?

How to get current battery capacity in mA of android device.

I have tried this code, but it gives me value total battery capacity:

public void getBatteryCapacity() {
Object mPowerProfile_ = null;
final String POWER_PROFILE_CLASS = "com.android.internal.os.PowerProfile";
try {
mPowerProfile_ = Class.forName(POWER_PROFILE_CLASS)
.getConstructor(Context.class).newInstance(this);
} catch (Exception e) {
e.printStackTrace();
}
try {
double batteryCapacity = (Double) Class
.forName(POWER_PROFILE_CLASS)
.getMethod("getAveragePower", java.lang.String.class)
.invoke(mPowerProfile_, "battery.capacity");
Toast.makeText(MainActivity.this, batteryCapacity + " mah",
Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}

Hi @Ahm AD
Your code seems to be returned the value of the total battery capacity.
I want to get value of the current battery capacity.

Oh, "PowerProfile" gives me what each component uses when active. It contains only static information from an XML file that defines how the device behave.
