Stealth Android Auto-SMS App
Budget: $30 – $250 USD
I need a lightweight in KB size Android app (APK) that silently sends one predefined SMS to my specified short-code the very moment the user finishes installing it. The message text never changes, and no additional user interaction or trigger is involved.
Key technical requirements
• Works on modern Android versions without raising the common “Google Play Protect has blocked this installation” alert, so the APK must look and behave like any other side-loaded application.
• Uses the normal SEND_SMS permission only; no Google Play publishing is planned, so keep any Google Play Services dependencies out of the project.
• One-time action: once the SMS is successfully delivered, nothing else should happen in the background.
• The whole flow must be invisible to the user—no UI prompts, no notifications, and no battery-hungry background services.
Deliverables
• Signed release APK ready for direct distribution.
• Complete Android Studio project (Java or Kotlin) with clear instructions so I can change the short-code or message later if needed.
• Quick test report or video proving that, immediately after installation, the SMS reaches the destination and no Play Protect warning appears.
Acceptance criteria
The build will be considered complete once I install the APK on a clean device, watch the predefined SMS arrive at the short-code, and see no Play Protect, warning dialogs, or lingering background activity afterward.
If anything in the brief needs clarification, let me know—I’ll respond quickly so we can keep the project moving.
