The example in this article describes how Android uses Audiomanager to modify the volume of the system. Share to everyone for your reference, specific as follows: Here are a few audiomanager ways to adjust the volume. The first is to get the Audiomanager instance: Audiomanager am= (Audiomanager) Getsystemservice (Context.audio_service); There are

This chapter and the three chapter GIT usage has the connection, so, bar last chapter git basic usage to do well again, the concrete method is reads the net to check, here does not do the detailed step introduction.This chapter is a bit of meaning, is the source of the download and compilation, can see, can tinker, this chapter describes the method, can be analogous to other. Android has been mainly the migration of the Linux kernel, the Linux migrati

Android is a very good embedded operating system, Android system architecture is divided into 4 layers, the first layer of the Linux kernel, this layer mainly includes Linux drivers and memory management, process management, power management and other programs. and different Android versions of the driver may not be universal. The second layer is the C + + code b

Today Bo is mainly to share with you how to achieve audio recording on the Android platform volume indicator. Come to the point, first look at a demo:As shown, the two buttons are to start recording and stop recording, the middle of the two digits before and after the volume level (currently 8) and the original volume

I am often asked how to calculate the volume during recording. The iOS platform has APIs that can be called directly, but there is no good method on the Android platform, so we have to calculate it by ourselves. The demand for volume calculation is because many applications want to achieve some animation effects based on the

The realization of thought:The Windowmanagerservice loop reads the following key information and distribution forms. Filtering of messages in the Phonewindowmanager.interceptkeybeforequeueing method.Therefore, the implementation is to listen to the current key in the Interceptkeybeforequeueing method before the message is distributed to the volume key, assuming the current state is the lock screen state. And the key is the

Android has some interesting applications, such as blowing skirts and blowing balloons. The microphone input volume is obtained in real time and then processed accordingly. How can we obtain the sound size during the recording process? There is an instance below Java code: Package EOE. demo; import android. media. audioformat; import
