In this way, dynamic generation of webview can avoid memory leaks, but this will cause some models of webview to click on the hyperlink and cause the program to crash. The temporary solution is to prohibit clicks and need to rewrite webview.

Public class MyWebview extends WebView {public MyWebview (Context context) {super (context);} public MyWebview (Context context, AttributeSet attrs) {super (context, attrs);} public MyWebview (Context context, AttributeSet attrs, int defStyleAttr) {super (context, attrs, defStyleAttr);} @ Override public boolean onTouchEvent (MotionEvent event) {return false;}}

This avoids program crashes.

Manual release of webview memory is required when 2.activity is closed

@ Override protected void onDestroy () {super.onDestroy (); if (webview_projectinfo! = null) {webview_projectinfo.removeAllViews (); webview_projectinfo.destroy (); webview_projectinfo = null; ll_webview.removeAllViews (); ll_webview = null }} the above is about the article on "how to solve memory leaks when using webview in Android".
