From Android Studio in Kotlin, im trying to pass my prompts over to my lambda function in aws. Im getting an exception that doesnt really matter. i will point out where in a moment. i want to by pass this exception and keep running my code, as the exception doesnt matter, and i think everything will be working just fine.
Here is part of my code:
findViewById<Button>(R.id.vcsendButton).setOnClickListener {
Thread(){
// taking user input, and changing the lambda function to process it
val userPromptvc = inputFieldvc.text.toString()
val userPromptvcTwo = inputFieldvcTwo.text.toString()
val userPromptvcThree = inputFieldvcThree.text.toString()
val userPromptvcFour = inputFieldvcFour.text.toString()
val userPromptvcFive = inputFieldvcFive.text.toString()
val userPromptvcSix = inputFieldvcSix.text.toString()
// below is letting our Lambda Function Env Var take a second to update
// then we will go ahead and invoke it now that its done updating with user input.
// invokeLambdaNova()
// invoke lambda actual function code below for testing
//Log.d("LambdaInvokeNova", "Starting invokeLambda()")
val client = OkHttpClient.Builder()
.connectTimeout(30000, TimeUnit.SECONDS)

//Below is myNovaReelFunction function URL
// val url = "https://[lambdafunctionurl].lambda-url.us-east-1.on.aws/"
//Below is myNovaReelFunctionTwo function URL
val url = "https://[lambdafunctionurl].lambda-url.us-east-1.on.aws/"
// temp changing
//val jsonPayload = "{\"prompt\":\"$userPromptvc\"}"
//Log.d("LambdaInvokeNova", "Payload prepared: $jsonPayload")
val jsonPayload = """

"prompt": "$userPromptvc",
"prompt2": "$userPromptvcTwo"
}
""".trimIndent()
val requestBody = jsonPayload.toRequestBody("application/json".toMediaType())
Log.d("LambdaInvokeNova", "Request body created")
//inputFieldvc.setText("")
val request = Request.Builder()
.url(url)
.post(requestBody)
.build()
Log.d("LambdaInvokeNova", "Request built: $request")
client.newCall(request).enqueue(object : Callback {
override fun onFailure(call: Call, e: IOException) {
Log.e("LambdaInvokeNova", "Failed to hit API: ${e.message}", e)
}
override fun onResponse(call: Call, response: Response) {
Log.d("LambdaInvokeNova", "Received response from API")
// Ensure response body is not null
val responseBody = response.body?.string()
if (responseBody == null) {
Log.w("LambdaInvokeNova", "Response body is null")
return // Exit if no body
}

// Parse the JSON response
val jsonResponse = JSONObject(responseBody)

val futureObjectKey = bodyJson.getString("futureObjectKey")
// Log.d(

val actualLink = presignedUrlString // <-- Replace with your link
// Create the HTML string with the hyperlink
val htmlLink = "<a href=\"$actualLink\">Click here to download your video!</a>"
// Set the text to the TextView, interpreting the HTML
// Use HtmlCompat.fromHtml for better compatibility across Android versions
@Suppress("DEPRECATION") // For older versions of Android
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
linkTextView.text = Html.fromHtml(htmlLink, Html.FROM_HTML_MODE_COMPACT)
} else {
linkTextView.text = Html.fromHtml(htmlLink)
}
// Make the links within the TextView clickable
linkTextView.movementMethod = LinkMovementMethod.getInstance()
}
} else {
Log.w("JSONParsing", "Missing key: futureObjectKey")
}
} catch (e: org.json.JSONException) {
Log.e("LambdaInvokeNova", "Error parsing JSON: ${e.message}", e)
}
} else {
Log.e("LambdaInvokeNova", "HTTP error: ${response.code} - ${response.message}")
}
}
})
}.start()
}
This is the line giving me the exception:
val bodyString = jsonResponse.getString("body")
If you provide code, please update my existing code so it works please. Thank you!
