I need a lightweight Android utility that does just one thing: the user opens the app, manually types or pastes a mobile number (with country code), writes a short text, taps a single button and that text is delivered to that number through WhatsApp. No registration, no extra screens—only the two input fields and the action button. I am fine with Java or Kotlin in Android Studio, as long as the final APK runs smoothly from Android 8 onward and follows WhatsApp’s allowed intent or API approach. If direct sending is blocked, opening the chat pre-filled and ready to hit “Send” is acceptable, but please highlight in advance which behavior you will be able to achieve. Deliverables: • Installable APK for testing • Clean, commented source project I can re-compile in Android Studio If you have a quick, reliable method to fulfill this, let’s get started.

Let me update you steps So your app will work exactly like: =>User pastes number with country code =>User types message =>Taps Send via WhatsApp =>WhatsApp opens → chat is opened → message is already written → user taps Send. No login, no permissions, no background tricks, no Play-Store risk. directly by third Party app could not send message because whatsapp does not provide public API to send. other way is to send by Business API of wahtsapp. Let we chat for short time so decide what needs to do I am ready to start Immediately Best Regards Jitendra Sharma

Hello. I can deliver a lightweight Android utility built in Kotlin or Java that allows users to enter a phone number with country code, write a short message, and open WhatsApp with the chat pre-filled using the official WhatsApp Intent API. The app will consist of a single screen with two input fields and one action button, following Android Material guidelines for clarity and stability. Since WhatsApp does not allow silent or direct message sending without user interaction, the implementation will open the WhatsApp chat with the message ready to be sent, fully compliant with WhatsApp’s policies. The app will support Android 8.0 (API 26) and above, with proper intent handling, validation, and graceful error messages if WhatsApp is not installed. I will ensure clean, well-documented code that can be easily recompiled in Android Studio without additional configuration. Input validation will include phone number formatting checks and empty-field handling to prevent runtime errors. The final deliverables will include an installable APK for testing and the complete Android Studio project source. The solution will be optimized for fast launch time, minimal permissions, and long-term maintainability. Regards, Justin.

Hello, I hope you are doing well. I’m a lightweight Android dev who builds focused tools that do one task well. I’ll deliver a two-input app (phone with country code and message) plus a single action button, targeting Android 8+. It will use a WhatsApp Intent to either send directly or open a pre-filled chat, with a clear note if only the pre-fill is possible. You’ll get a clean, commented source project ready to recompile in Android Studio and an APK for testing. In similar small projects I’ve implemented WhatsApp intents using Java/Kotlin and Android Studio, keeping the code minimal, reliable, and easy to customize. I’ll ensure the app is fast, tiny, and well-documented. I can complete this in 3 days for a budget around the range. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan
