WebViewの終了処理

投稿日: 2014/09/02 作成者: skelabo

ログにエラーがつらつらと出てくるので。

web.stopLoading();

web.clearCache(true);

web.clearHistory();

try

{

Thread.sleep(100);

}

catch(Exception e)

{

e.printStackTrace();

}

web.setWebChromeClient(null);

web.setWebViewClient(null);

unregisterForContextMenu(web);

web.destroy();

web = null;

キャッシュクリア後sleepしないとクリアされない模様。参考
