PI57332: WHEN RESUMING MOBILEFIRST APPLICATION FROM BACKGROUND, A NEW WEBVIEW INSTANCE IS CREATED AND PREVIOUS INSTANCE IS NOT CLEARED.

IBM MobileFirst Platform Foundation Interim Fix README for 7.1

APAR status

• Closed as program error.

Error description

• The Cordova Webview does not get destroyed when the MobileFirst
  Platform Foundation application goes to the background. When the
  application resumes, a new WebView instance is created and the
  old WebView is still not cleared. These uncleared WebViews will
  take up memory and should be properly destroyed.

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * All users that use the Cordova WebView for Android.          *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * The Cordova WebView does not get destroyed when the          *
  * application goes into the background. It remains in a        *
  * detached state, and will get cleared only when the Android   *
  * OS kills it to free up memory. Resuming the application will *
  * create a new Cordova WebView instance. When the Cordova      *
  * WebView handles being destroyed, it never calls the Android  *
  * WebView's destroy() method, thus it lingers around in a      *
  * detached state. Calling that method, the Cordova WebView     *
  * will have the expected behavior.                             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *
