我创建了一个简单的应用程序来测试泄漏.我在xml布局文件中使用WebView启动一个Activity,并使用活动上下文进行膨胀. Js off.一切都默认期望一个简单的webViewClient在WebView中保持重定向.它每次泄漏.
我做了大量的研究,防止这种情况的唯一方法是使用另一个进程启动WebViewActivity并在onDestroy中杀死它.但这种方法有其自身的缺点.
每次运行5.0的所有设备都会发生泄漏,未检查4.3及以下版本.
泄漏信息粘贴在下面：
In com.example.webviewmemoryleaktest:1.0:1.
* com.example.webviewmemoryleaktest.WebViewActivity has leaked:
* GC ROOT android.os.ResultReceiver$MyResultReceiver.this$0
* references org.chromium.content.browser.ContentViewCore$2$1.this$1 (anonymous class extends android.os.ResultReceiver)
* references org.chromium.content.browser.ContentViewCore$2.this$0
* references org.chromium.content.browser.ContentViewCore.mContext
* references com.android.webview.chromium.ResourcesContextWrapperFactory$WebViewContextWrapper.mBase
* leaks com.example.webviewmemoryleaktest.WebViewActivity instance

感谢是否有人可以提供帮助.谢谢！
解决方法
private ResultReceiver mResultReceiver = new ResultReceiver(new Handler()) {
@Override
public void onReceiveResult(int resultCode,Bundle resultData) {
getContentViewClient().onImeStateChangeRequested(
resultCode == InputMethodManager.RESULT_SHOWN
|| resultCode == InputMethodManager.RESULT_UNCHANGED_SHOWN);
if (resultCode == InputMethodManager.RESULT_SHOWN) {
// If OSK is newly shown,delay the form focus until
// the onSizeChanged (in order to adjust relative to the
// new size).
// TODO(jdduke): We should not assume that onSizeChanged will
// always be called,crbug.com/294908.
getContainerView().getWindowVisibleDisplayFrame(
mFocusPreOSKViewportRect);
} else if (hasFocus() && resultCode
== InputMethodManager.RESULT_UNCHANGED_SHOWN) {
// If the OSK was already there,focus the form immediately.
assert mWebContents != null;
mWebContents.scrollFocusedEditableNodeIntoView();
}
}
};
@Override
public ResultReceiver getNewShowKeyboardReceiver() {
return mResultReceiver;
}
使mResultReceiver成为私有的.
