问题 I'm developing an app that should alert an user if is near a place. and of course have to do that also if the phone is in idle. With DOZE now I understood that I have to whitelist my app, and to do that I saw that I can start an intent with the action request thanks to Buddy's answer in this post Intent intent = new Intent(); String packageName = context.getPackageName(); PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); if (pm.isIgnoringBatteryOptimizations

问题 I am using Arduino Nano and various Li-Fe , Li-Po batteries of 9.9V , 6.6V and 3.7V. I can read the voltage of the battery using Arduino . My Arduino works at 5V so for batteries like 9.9V and 6.6V I have used a voltage divider using two 10k resistors.But the problem is I need to read the the % of charged battery , I tried something in the code but I am not sure about it. Please anyone help me with it. My code is: #define cellPin A0 const float mvpc = 4.55 ; //measured voltage of arduino

问题 Here my question is, can we identify, how much battery life my android application is utilising. Because I developed an app based on GPS as well as network, service, broadcast receivers, so I have battery drain problem, so first of all i want to know that how much battery percentage is my application using. Any idea. Thanks in advance. 回答1: It is difficult to say exactly how much battery life is used by specific application. But, you can refer following links which may give you a little idea.

问题 I found that in the manifest can not be registered (intent-filter battery low, battery changed). I need to get the notification when the battery is fully charged. when I have a running app so it is working, but when I close the application so it does not work. I need the receiver to run in the background when the application is closed. Main.class IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED); mContext.registerReceiver(this.batteryInfoReceiver,filter); private

问题 How can I obtain the temperature of the Battery in IOS programatically. Also are there any API's in IOS that would give us any information on the Battery Manufacturer etc. Currently I am able to obtain the Battery level and charging status . Wanted to check if there is any other Battery related information that we can obtain in IOS 回答1: That is not possible in the public API. 回答2: As @Fogh correctly indicated, that isn't possible using the public API. The data is available in IOKit , but

问题 I'm just wondering if is there any possibility to obtain battery status in broadcast receiver class that fires on ACTION_POWER_CONNECTED? Documentation suggest not, but it is always worth to ask :) Cheers Ray 回答1: Call registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)) . The Intent that is returned is the last-broadcast ACTION_BATTERY_CHANGED broadcast, which has your battery status in its extras (see BatteryManager for the keys). If you determine that you are calling it
