A high-performance webkit kernel browser is built in the Android mobile phone. It is encapsulated as a WebView component in the SDK.
What is webkit
WebKit is a software framework included in Mac OS X v10.3 and later versions (for v10.2.7 and later versions, you can also obtain it through software updates ). WebKit is also the foundation of Mac OS X's Safari web browser. WebKit is an open-source project. I

Activity level: To control whether each activity turns on hardware acceleration, simply add the android:hardwareaccelerated attribute to the activity element3. Window level: Note: It is not supported to turn off hardware acceleration at the window levelGetWindow (). SetFlags ( WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED, WindowManager.LayoutPa

Detailed explanation of WebView in Android:
1. Concept:
WebView (network view) can load a display page, which can be viewed as a browser. It uses the WebKit rendering engine to load the Display Web page.
