Intent is very common in Android programming, and it has been shown in "Android" to use bundles to transfer values between multiple activity (clicking the Open link) to wake up other activity and pass data between the activity. In fact, the role of intent is far from this, it can also invoke other inherent programs in the system, such as making calls, sending text messages and so on. OnKeyDown is also the c

Android deep exploration and HAL-driven development (Volume 1)-Chapter 7, android-driven developmentRelationship between applications, libraries, kernels, and drivers
From top to bottom, a software system can be divided into applications, libraries, operating systems (kernels), and drivers. Developers can focus on what they are familiar with. For adjacent layers,

The first step to creating an excellent audio experience is to understand the type of audio stream that your application will use.
The Android system maintains independent audio channels for playing music, alarms, notifications, incoming call ringtones, system sounds, and call calls.) volume, an
Today, we have a requirement in the project to use seekbar to control the volume.
I thought it was a very simple thing (it was indeed a very simple thing), but at the beginning it could not achieve what I wanted. After some modifications and searches, the solution was finally solved. In the process of solving this problem, I also found some shortcomings in my understanding of Android.
So, let's discuss it

Good user experience is predictable. If your application needs to play multimedia, it is vital that you can use the hardware or software of your device to control the volume, such as Bluetooth headsets or microphones.
Similarly, when appropriate, your application should provide media playback operations s

However, the possible disadvantage of the maximum value is that the extreme data will be affected, so that the subsequent calculation of the decibel value fluctuation is relatively large.
