There's no need to initialize the Android interface from JavaScript. The WebView automatically makes it available to your web page. So, when a user clicks the button, the showAndroidToast function uses the Android interface to call the WebAppInterface. Note: The object that is bound to your JavaScript runs in another thread and not in the thread in which it was constructed.

This can be a very useful feature or a dangerous security issue. You should also not allow the user to navigate to other web pages that are not your own, within your WebView. Instead, allow the user's default browser application to open foreign links—by default, the user's web browser opens all URL links, so be careful only if you handle page navigation as described in the following section. When the user clicks a link from a web page in your WebView , the default behavior is for Android to launch an app that handles URLs.

Usually, the default web browser opens and loads the destination URL. However, you can override this behavior for your WebView , so links open within your WebView. You can then allow the user to navigate backward and forward through their web page history that's maintained by your WebView.

If you want more control over where a clicked link loads, create your own WebViewClient that overrides the shouldOverrideUrlLoading method. Now when the user clicks a link, the system calls shouldOverrideUrlLoading , which checks whether the URL host matches a specific domain as defined above. If the URL host does not match, then an Intent is created to launch the default Activity for handling URLs which resolves to the user's default web browser.

When your WebView overrides URL loading, it automatically accumulates a history of visited web pages. You can navigate backward and forward through the history with goBack and goForward.

For example, the following shows how your Activity can use the device Back button to navigate backward:. The canGoBack method returns true if there is actually web page history for the user to visit.

Likewise, you can use canGoForward to check whether there is a forward history. If you don't perform this check, then once the user reaches the end of the history, goBack or goForward does nothing. These changes cause a WebView object's activity to be destroyed and a new activity to be created, which also creates a new WebView object that loads the destroyed object's URL. To learn more about handling configuration changes during runtime, read Handling configuration changes. By default, requests to open new windows are ignored.

This is true whether they are opened by JavaScript or by the target attribute in a link. You can customize your WebChromeClient to provide your own behavior for opening multiple windows. Caution: To keep your app more secure, it's best to prevent popups and new windows from opening. The safest way to implement this behavior is to pass "true" into setSupportMultipleWindows but not override the onCreateWindow method, which setSupportMultipleWindows depends on.

This module exploits CVE in Android to install a payload into another application. The payload APK will have the same signature and can be installed as an update, preserving the existing This module is a stub that provides all of the features of the Metasploit payload system to exploits that have been launched outside of the framework.

This module suggests local meterpreter exploits that can be used. The exploits are suggested based on the architecture and platform that the user has a shell opened as well as the available exploits Platforms : all Refs : source , docs. Allwinner 3.
