batterymanager

I have tried powerprofile of Android....I have tried this code...but it gives me 1000 answer every time in all the devices... Is there any other way in android to get battery capacity... Eg.if mobile device capacity is 2000mAh it should return me 2000 public Double getBatteryCapacity() { Object mPowerProfile_ = null; double batteryCapacity = 0; 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) { // Class not found? e.printStackTrace(); } try

I just basically want to add about 20 and sometimes 80 Proximity Alerts with no time expiration with a radius of around 500 meters. Just wondering whether by doing this will suck up the battery real quick? also would it make any difference by reducing the radius? This will definitely eat your battery real quick. You never want to be setting more than a couple of proximity alerts in any case, the use-case you describe isn't really catered for in Proximity Alerts. Proximity Alerts should switch between GPS and Network as required, but in my experience they tend to stick to GPS whenever it's

Following this guide https://developer.android.com/training/monitoring-device-state/battery-monitoring.html I made a receiver that should log battery info to a file every time charger is plugged or unplugged. The activity reads the content of this file and displays it on screen. This is supposed to work always regardless of the app running, but it doesn't. It only registers if the app is open/in memory, when I clear the memory or reboot it stops working. Manifest: <receiver android:name=".Receiver"> <intent-filter> <action android:name="android.intent.action.ACTION_POWER_CONNECTED"/> <action

Is it possible to calculate remaining battery time in hours and minutes? Also, would it be able to calculate this time depending on if I'm using a certain app? Is it even possible to get such information? If you could please give me advice on how to do that, I'd be very thankful. Estimating the remaining battery life is based on analytics. As the other people said you have to listen for battery level changes and in addition you have to keep track of them. After some time you will have enough data to calculate what is the average time the battery lasts. In addition you know when the battery

My app has a broadcast receiver to listen for changes to ACTION_POWER_CONNECTED , and in turn flag the screen to stay on. What I am missing is the ability for the app to check the charging status when it first runs. Can anyone please help me with code to manually check charging status? Thanks to CommonsWare here is the code I wrote. public class Power { public static boolean isConnected(Context context) { Intent intent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)); int plugged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1); return plugged ==
