android battery monitor app

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 status, such as when the device enters a low

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

But after all, this program is based on the premise that the official does not support, and home button monitoring in many devices will have compatibility issues, so we do not recommend this.Scenario Three: Use Activitylifecyclecallbacks to monitor the life cycle of all activ
