Toast Plugin

The ToastPlugin is included as a basic example of how the plugin architecture works. It provides a simple way to display native “Toast” messages (short, non-blocking pop-ups).

Features

• Display toasts from native Java code.
• Display toasts triggered from JavaScript in the WebView.
• Configurable default duration (short or long).

Setup & Configuration

1. Enable Plugin: Ensure ToastPlugin is listed in the plugins.enabled property in app/src/main/assets/swv.properties.

   plugins.enabled=...,ToastPlugin
   

2. Internal Logic: The ToastPlugin.java class uses a static initializer block to automatically register itself. During initialization, it adds a JavaScript interface named ToastInterface to the WebView.

Usage

From Native Code

1. Get the plugin instance from the PluginManager.
2. Call its showToast method.

// Example from another class, like Playground.java
PluginInterface plugin = SWVContext.getPluginManager().getPluginInstance("ToastPlugin");
if (plugin instanceof mgks.os.swv.plugins.ToastPlugin) {
    ((mgks.os.swv.plugins.ToastPlugin) plugin).showToast("Hello from Native!");
}

From JavaScript

After the page has loaded, you can call the methods of the injected window.Toast helper object.

// Check if the interface is ready
if (window.Toast) {
  // Show a toast with the default duration
  window.Toast.show("Hello from JavaScript!");

  // Show a toast with a long duration
  window.Toast.showLong("This JavaScript toast stays for longer.");
}
