This article illustrates the Android implementation of a dynamic display of battery status, power and charge, and is a very common feature in the development of Android applications. Share for everyone to use for reference. The specific methods are as follows:
Use the battery
minimize the power consumption, you can use the intent obtained above to obtain the level and scale of the current power, and then calculate the percentage of the current power.
Sample Code:
int level = battery.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);int scale = battery.getIntExtra(BatteryManager.EXTRA_SCALE, -1);float batteryPct = level / (float)scale;Monitor significant changes in battery power
Generally, we do not need to constantly monitor th

This article describes the implementation of Android programming to monitor battery status. Share to everyone for your reference, specific as follows:
Recently in the development of a GPS-related project, because it involves the use of GPs, it is well known that GPS is quite power consumption, so think how to know the current electricity, and when the electricit

Android Battery status monitoring
If you want to monitor changes in the battery status, you need to dynamically register: android. intent. action. BATTERY_CHANGED: After receiving the Action, you can obtain the information you nee
Android Developers can use the broadcastreceiver mechanism to obtain the action_battery_changed intent of the battery change, and then obtain the battery status of the current Android device.Procedure:1. Create an intentfilter that listens to the action_battery_changed event
status
In general, if you keep monitoring the battery status, it may have a great impact on the battery itself, or even exceed the influence of the program itself, which is a little worth the candle, therefore, it is necessary to monitor only major changes in the battery

Inspired by colleagues, suddenly found a few interesting and useful Web API, did not think of the front end there are so many interesting things to play ~ ~ Too much.1. Battery Status APINavigator.getbattery (): This API returns a Promise object that gives a Batterymanager object that contains information such as whether the device is charging, power, and how long and how long it will take to charge.Chrome
The share of mobile devices is growing exponentially in network traffic, and the amount of network traffic it contributes is so great that we have created some APIs and design ideas for mobile devices alone. A very typical example is the common-system battery status API, which allows an application to learn about the battery state information of a device. This ar
