最近在項目開發中用webview去顯示加載h5內容，而h5內容中有一些圖片，並且可以點擊放大看圖。在比較變態的測試方法（點擊圖片放大，關閉當前界面，再進入，再點擊圖片放大，大概10次左右）後，會導致圖片點擊沒反映了（其實就是webview內存泄漏了）。錯誤信息如下：

話不多說了，直接分享一下解決方法吧！
1、在初始化時，customWebView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
2、在Activity的onDestroy時，添加下面兩句話：
customWebView.removeAllViews();
customWebView.destroy();
