WebViewRenderProcessClient

public abstract void onRenderProcessResponsive(
    @NonNull WebView view,
    @Nullable WebViewRenderProcess renderer
)

Called once when an unresponsive renderer currently associated with view becomes responsive.

After a WebView renderer becomes unresponsive, which is notified to the application by onRenderProcessUnresponsive, it is possible for the blocking renderer task to complete, returning the renderer to a responsive state. In that case, this method is called once to indicate responsiveness.

No action is taken by WebView as a result of this method call.

public abstract void onRenderProcessUnresponsive(
    @NonNull WebView view,
    @Nullable WebViewRenderProcess renderer
)

Called when the renderer currently associated with view becomes unresponsive as a result of a long running blocking task such as the execution of JavaScript.

If a WebView fails to process an input event, or successfully navigate to a new URL within a reasonable time frame, the renderer is considered to be unresponsive, and this callback will be called.

This callback will continue to be called at regular intervals as long as the renderer remains unresponsive. If the renderer becomes responsive again, onRenderProcessResponsive will be called once, and this method will not subsequently be called unless another period of unresponsiveness is detected.

The minimum interval between successive calls to onRenderProcessUnresponsive is 5 seconds.

No action is taken by WebView as a result of this method call. Applications may choose to terminate the associated renderer via the object that is passed to this callback, if in multi-process mode, however this must be accompanied by correctly handling onRenderProcessGone for this WebView, and all other WebViews associated with the same renderer. Failure to do so will result in application termination.
