Take a look at the documentation on Battery Manager.
You'll be able to see what these constant values mean. For example, the value 2
that you get corresponds to BATTERY_HEALTH_GOOD
. You can check that here: Link.
In your activity, you can check your integer variable health
against these values like:
if (health == BatteryManager.BATTERY_HEALTH_GOOD) {
// do something, update a textview, show a Toast
} else if (health == BatteryManager.BATTERY_HEALTH_OVERHEAT) {
// do something else, show a warning
} else if. . . . // check for however many values or check for all
This way, you won't need to consider the actual value(numerical value) that health
variable holds.
