Android Webview: Cannot call determinedVisibility() - never saw a connection for the pid

Question

I have a Android Webview and when I click on a link to download a file (image of pdf etc) I got a error message.

Error message:
Cannot call determinedVisibility() - never saw a connection for the pid

Any idea what I do wrong? Who can help please!?

Solution 1

Just a bit of configuration:

    webview.getSettings().setJavaScriptEnabled(true);
    webview.getSettings().setDomStorageEnabled(true);

Solution 2

I got the same error and Burhans solution was not helping me. I think things went wrong when you´re trying to load different urls too fast.

Edit: Found a better solution credits go to user2652394 WebView must be loaded twice to load correctly

You have to do something like this:

        webView.postDelayed(new Runnable() {

            @Override
            public void run() {
                webView.loadUrl(landingpage);
            }
        }, 500);

Solution 3

I faced the same issue.

Was solved by giving a WebView a static height (ie 300dp) or specifying minHeight value.

Background

Here is the source code of the method in the browser engine that gives the error (BindingManagerImpl.java), from Chromium source:

@Override
public void determinedVisibility(int pid) {
    ManagedConnection managedConnection;
    synchronized (mManagedConnections) {
        managedConnection = mManagedConnections.get(pid);
    }
    if (managedConnection == null) {
        Log.w(TAG, "Cannot call determinedVisibility() - never saw a connection for the pid: "
                + "%d", pid);
        return;
    }

Analysis

It's a rendering warning from content.

Consecutive calls to loadUrl cause a race condition. The problem is that loadUrl("file://..") doesn't complete immediately, and so when you call loadUrl("javascript:..") it will sometimes execute before the page has loaded.

This problem in my case produce by incorrect settings in layout properties. I had used:

    <WebView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/webView"
    android:layout_below="@+id/textView"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="false"
    android:layout_alignWithParentIfMissing="false" />

Instead of setting:

    <WebView
    android:id="@+id/webView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_below="@+id/textView" />

The problems had been solved, when I removed "layout_alignParent" settings.

A helpful answer should always explain why the problem (error) is occurring as well as explaining why the suggested answer (your code) should work or fix it. Without any explanation this answer is not helpful - this is very important especially for a question that already has a number of answers submitted.
