Buena tarde Tengo experiencia desarrollando aplicaciones Android y automatizando procesos de extracción de información desde documentos PDF. Para este proyecto desarrollaré una aplicación que procese localmente las guías, identifique automáticamente cualquiera de los dos formatos proporcionados y extraiga los datos necesarios (nombre, teléfono y número de guía) de forma confiable. La aplicación mostrará los registros encontrados y, con un solo clic, abrirá el chat mediante el enlace oficial de WhatsApp con el mensaje prellenado, sin depender de la API de WhatsApp. La solución será compatible con Android 8.0+, entregando el APK, código fuente completamente documentado y una arquitectura preparada para incorporar nuevos formatos de guías en el futuro si fuera necesario. Podemos comentarlo por chat para revisar los ejemplos de las guías y definir la mejor estrategia de extracción para garantizar la mayor precisión posible.

✋ ¡Hola! ✋ OBJETIVO DEL PROYECTO: CREAR UNA APLICACIÓN PARA ANDROID QUE EXTRAIGA DATOS DE ENVÍO DE ARCHIVOS PDF Y ABRA CHATS DE WHATSAPP CON INFORMACIÓN PREDETERMINADA. Los requisitos del proyecto se han revisado minuciosamente y la aplicación se puede entregar con una experiencia de usuario sencilla y confiable. • Procesar archivos PDF localmente y reconocer con precisión las dos plantillas de guías de envío. • Extraer el nombre del destinatario, el número de teléfono y el número de seguimiento de cada guía. • Mostrar todos los registros detectados con una acción individual de "Enviar WhatsApp". • Abrir el chat oficial de WhatsApp usando un mensaje predefinido a través de la URL de enlace profundo. • Entregar un APK compatible con Android 8.0+ con código fuente Java bien comentado. Se han desarrollado aplicaciones similares de extracción de PDF y automatización de documentos para Android con análisis de datos preciso e integración de enlaces profundos de WhatsApp. <-- Preguntas --> 1. ¿Las dos plantillas de PDF siempre mantendrán el mismo diseño y la misma posición de los campos? 2. ¿Deben guardarse localmente los registros extraídos para futuras consultas o procesarse solo una vez? Espero poder conversar con usted para llegar a un acuerdo. Saludos cordiales, Elisha Mariam.

With over 5 years of experience in mobile app development, especially on the Android platform, I am confident in my ability to create the app you're looking for. Working with tools such as iText and PDFBox to parse PDF data is well within my skillset, as is customizing deep-links for WhatsApp messages. I have a strong eye for detail that will ensure that I can reliably recognize the two different guía formats you work with, even when they are embedded within a complex document structure. In terms of file management, while automated folder monitoring may not be necessary, I'm comfortable developing processes that allow you to easily select and process PDF files manually. Upon completion, I will provide you not only with an APK installable file but also the entire source code with detailed comments for future understanding and modifications. As evidence of my capabilities to handle this project efficiently, let me share a similar example from my past experience: while developing a tool for an e-commerce company, I extracted relevant logistic data from HTML shipping receipts and automatically sent customized messages through WhatsApp to clients. This demonstrates my expertise in handling semi-structured data extraction and deep-linking Whatsapp messages. Rest assured, by hiring me you are choosing reliability, quality and timely delivery.

I’ve built Android apps handling PDF data extraction and WhatsApp deep-link routing before—so this is straightforward. I’ll use Android Studio, target API 26+, and implement direct file picker integration to avoid folder monitoring. PDFBox will parse the files; I’ll hardcode regex templates for the two given formats to extract phone, name, and tracking ID. The list will show pre-filled WhatsApp URLs in `whatsapp://send?phone={}&text={}` with the exact message template. APK and source in a single repo with minimal dependencies. I can start today. Thanks, Andrii.

Hi, Looks like the main challenge here is reliably extracting the small set of fields from two fixed PDF templates and then opening WhatsApp with the right deep-link message. Since the PDFs are local and the formats are predictable, a simple template-based extractor should work without heavy OCR. I’ve done similar data extraction before on a logistics-related project where we pulled tracking numbers out of PDF invoices and built a small Android utility to open the carrier’s web chat with prefilled data. The same approach applies here—identify the bounding boxes of the key fields, map them to phone, name, and tracking number, then construct the WhatsApp URL. The biggest unknown is whether the PDFs use consistent fonts and spacing. If the layout drifts even slightly between files you may need to tweak the coordinates. I’d start with the two provided examples, hard-code the extraction rules, and add a quick visual check before sending. The deep-link part is straightforward; WhatsApp’s URL scheme is stable across Android 8+, so once you have the data the rest is just string interpolation. If you want to see a minimal example of PDF parsing plus deep-link handling, have a look at the Android utility I built for the logistics project (code is in the portfolio). Thanks, Denis.

Hello, I read your project details carefully. I understand that you need an Android application that can process shipping guide PDFs, extract customer information from two predefined templates and generate WhatsApp messages automatically through the official WhatsApp URL flow. I can develop an Android app that allows PDF upload, extracts the recipient name, phone number and tracking number locally, recognizes both courier guide formats and displays each result with an “Enviar WhatsApp” action. The generated message will be prefilled exactly according to your required format without using WhatsApp API. I have experience with Android development, PDF data extraction, Java/Kotlin, Android SDK and custom mobile workflows. I will focus on reliable template recognition, simple user experience and clean source code with proper comments. The final delivery will include the installable APK, complete source code and setup instructions. I can also test with your provided PDF examples to ensure both guide formats work correctly. One question: are the PDFs generated with selectable text, or are they scanned images requiring OCR? Can you provide the two courier guide samples so I can confirm the best extraction method before development? Best regards

@Lazarone1

hola, su aplicación android necesita automatizar la extracción de datos desde pdf y facilitar el envío de mensajes de whatsapp con un flujo simple y eficiente. puedo desarrollar una app compatible con android 8 o superior, con procesamiento local de pdf, reconocimiento de plantillas, extracción de datos y enlaces oficiales de whatsapp sin api. ¿podría compartir los ejemplos de las dos guías pdf para validar la estructura de extracción y garantizar la precisión?

@abdullahsaeeddev

Hi, I reviewed your requirements carefully, and I understand the complete workflow. The app will process one or multiple shipping guides from your PDF, recognize the two courier formats you provide, extract the required information (phone number, recipient name, and guide number), then display each record with a "Send WhatsApp" action that opens the official WhatsApp chat with your pre-filled message. Since the application only needs to support two fixed PDF templates, I'll build the extraction logic specifically for those layouts, making it reliable, fast, and easy to maintain if the templates change in the future. The entire process will run locally on the Android device, support Android 8+, and I'll deliver a clean APK together with well-structured, commented source code. I can start as soon as you share the final sample PDFs and will keep you updated throughout development. Best regards, Muhammad Abdullah Saeed

@predragr3

✅✅✅ Hi, there ✅✅✅ I have thoroughly reviewed your project requirements for developing an Android application to automate WhatsApp message sending based on shipment guides loaded in PDF format. I understand that the app needs to extract key data like customer phone number, recipient's name, and guide number from PDF templates, and then send pre-drafted messages to customers via WhatsApp without using the API. With my expertise in PDF data extraction using tools like iText and PDFBox, I am confident in my ability to reliably recognize the two specified guide formats and process the PDFs locally on the Android platform. I have experience in developing applications that handle manual file management tasks efficiently. To achieve the desired functionality, I propose a streamlined approach where the app will extract data from the PDF, list each record with a dedicated "Send WhatsApp" button, and upon user interaction, open the customer's chat with the pre-populated message containing the necessary details. I will ensure compatibility with Android 8.0+ and provide you with a well-commented APK and source code upon project completion. I look forward to discussing further details with you and demonstrating my capabilities. ✌️ Predrag ✌️

If the PDFs sometimes come as scanned images, an OCR step will be required to reliably pull the phone, name and guide number. I'd parse the file with PDFBox, find the fixed box for each template, and pull the three fields using a regex that matches the format. The app will then build the WhatsApp deep link and launch it via an intent, keeping everything local. A common pitfall is forgetting to request runtime storage permission, which makes the PDF picker crash on Android 9 and above. I'll add the permission check and fallback to the scoped storage API so the app works on all devices from Android 8 onward. Ready to start right away and deliver a clean APK with commented source.

Hi! I am a Senior Software Developer with extensive experience in mobile application development, and I am confident I can help you automate the WhatsApp messaging process from PDF files. I will utilize libraries like iText or PDFBox to accurately extract the necessary information from the two specified PDF templates, ensuring reliable recognition of key data such as the client's phone number, recipient's name, and tracking number. In a similar project, I developed a mobile app that extracted data from invoices and sent tailored messages to users via SMS, which required precise data extraction and user-friendly interfaces. My strong background in mobile development, combined with my proficiency in backend solutions, allows me to deliver clean and efficient code that meets your requirements. I would love to clarify a couple of points: what specific formats do the PDF templates follow, and do you have any particular design preferences for the app's user interface? Let’s chat further about how I can assist you with this project! Best regards, Jayvince

@JuanGarcia12001

Vi que necesitas una app nativa en Android que extraiga los datos de dos plantillas de PDF fijas y abra el chat con el mensaje prellenado mediante enlaces deep link (whatsapp://send), omitiendo la API oficial. He desarrollado herramientas similares en Kotlin usando PdfBox-Android para leer cajas de texto por coordenadas y renderizar la lista interactiva lista para enviar con un clic. ¿Podrías adjuntarme las dos plantillas de muestra para evaluar la estructura y definir el parser exacto?

Hello APP ANDROID WHATSAPP DESDE PDF needs accurate extraction and a simple delivery workflow, not a complex system — the main goal is turning shipment guides into ready-to-send customer messages with minimal manual work. I would build the Android app with local PDF processing using a library such as PDFBox/iText, extracting the recipient name, phone number, and tracking number from the two known guide templates. After parsing, the app would generate the WhatsApp deep links with the predefined message format so users can review the detected records and send directly through WhatsApp. A common edge case with PDF extraction is that text positions can shift between files even with the same template, causing incorrect field mapping, so I would add validation around phone numbers and tracking formats before generating the message links. Do you already have the two PDF samples with selectable text, or are they scanned images that will require OCR processing? Looking forward to helping you automate this shipment notification flow.
