How to find the battery recharge time of android mobile programatically?

I wanted to know that how can we find how much time android device will take to fully charge its battery.

For example if my battery is 0% charged then how long it will take to charge full i.e. 100%, same if my device is 70% charge so if i connect charger now then how long it will take to full charge my device.

This worked for me:

private void batteryLevel() {
        BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver() {
            public void onReceive(Context context, Intent intent) {
                context.unregisterReceiver(this);
                int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
                int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
                int level = -1;
                if (rawlevel >= 0 && scale > 0) {
                    level = (rawlevel * 100) / scale;
                }
                batterLevel.setText("Battery Level Remaining: " + level + "%");
            }
        };
        IntentFilter batteryLevelFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
        registerReceiver(batteryLevelReceiver, batteryLevelFilter);
    }

You should read the official documentation about this. Basically you'll need to use BatteryManager class to find out current state of battery level.
