Android Enables automatic conversion of mobile phone vibrations and ringtones based on conditions

Android content:

• Why is the webpage view of Android displayed on a black screen?
• In Android, how does one handle changes in the screen direction when the progress dialog box and background thread activity?
• How does Android call oncreat () multiple times in an activity ()
• How does Android create a textview with a folding effect?
• Android app auto-start

In this example, the current mode of the mobile phone is changed based on the "status" of the mobile phone.
When the front of the phone is up, the phone is in the ring state, and when the back of the phone is up, the phone is in the mute state.
To implement this example, you need to use the built-in sensors of the mobile phone and implement corresponding methods to determine the status of the mobile phone. At the same time, you also need to use the audiomanager class of the mobile phone to change the Mobile Phone mode.
First, add the following content to the androidmanifest. xml file:Code:
<Uses-Permission Android: Name = "android. Permission. Vibrate"/>

The function of this line of code is to makeProgramYou can use the vibrate mode of the mobile phone.
The specific implementation code and corresponding comments are given below:
