What is an Intent?

An Intent is a 'passive' data structure that holds an abstract description of an action to be performed. It acts as the glue between different components—even those in different applications. For your Revochamp project, Intents are the mechanism used to transition from your Flutter UI to a native Android 'Preview' or to share a generated code snippet to an external editor.

Explicit Intents

Explicit intents specify exactly which component (class name) should be started. You use these for internal navigation within your native Android Runner code where you know the exact target class.

// Navigating to a specific native Activity
val intent = Intent(this, AIEditorActivity::class.java).apply {
    putExtra("WIDGET_TYPE", "FAB")
    putExtra("THEME_COLOR", "#007AFF")
}
startActivity(intent)

// Navigating to a specific native Activity
val intent = Intent(this, AIEditorActivity::class.java).apply {
    putExtra("WIDGET_TYPE", "FAB")
    putExtra("THEME_COLOR", "#007AFF")
}
startActivity(intent)

Implicit Intents

Implicit intents do not name a specific component. Instead, they declare a general action to be performed (e.g., 'view a map' or 'send an email'). The Android system then finds all apps that can handle that action using Intent Filters and lets the user choose. This is vital for Revochamp's 'Export' and 'Share' features.

// Sharing generated code to any available editor app
val sendIntent = Intent().apply {
    action = Intent.ACTION_SEND
    putExtra(Intent.EXTRA_TEXT, "// Generated by Revochamp\nprintln('Hello World')")
    type = "text/plain"
}

val shareIntent = Intent.createChooser(sendIntent, "Export Code To:")
startActivity(shareIntent)

// Sharing generated code to any available editor app
val sendIntent = Intent().apply {
    action = Intent.ACTION_SEND
    putExtra(Intent.EXTRA_TEXT, "// Generated by Revochamp\nprintln('Hello World')")
    type = "text/plain"
}

val shareIntent = Intent.createChooser(sendIntent, "Export Code To:")
startActivity(shareIntent)

Intent Filters: Receiving Requests

If you want the Revochamp app to open when a user clicks a specific link (Deep Linking), you must declare an Intent Filter in your AndroidManifest.xml. This tells the OS, 'My app is capable of handling this specific type of data or action.'

Frequently Asked Questions

How do I pass large amounts of data through an Intent?

Intents have a size limit (approx. 1MB). For passing large AI models or long strings in Revochamp, do not use 'putExtra'. Instead, save the data to a file or a database and pass the 'URI' or 'ID' through the Intent.

What is a PendingIntent?

A PendingIntent is a token that you give to another application (like the Notification Manager), which allows that application to execute an Intent on your behalf later, even if your app's process is killed.

Why is my Implicit Intent crashing on some devices?

If no app on the device can handle your implicit intent, the app will crash. In 2026, you must always check if there is an available app using 'resolveActivity' or wrap the 'startActivity' call in a try-catch block.

// Navigating to a specific native Activity val intent = Intent(this, AIEditorActivity::class.java).apply { putExtra("WIDGET_TYPE", "FAB") putExtra("THEME_COLOR", "#007AFF") } startActivity(intent)

// Sharing generated code to any available editor app val sendIntent = Intent().apply { action = Intent.ACTION_SEND putExtra(Intent.EXTRA_TEXT, "// Generated by Revochamp\nprintln('Hello World')") type = "text/plain" } val shareIntent = Intent.createChooser(sendIntent, "Export Code To:") startActivity(shareIntent)
