If you searched for "sellmyapp teen patti not working" and landed here, you're likely troubleshooting a Teen Patti app or template bought from a marketplace like SellMyApp. I’ve fixed similar template issues for clients and indie teams: the problem often looks catastrophic at first—crashes on launch, blank screens, failed multiplayer lobbies—but most failures trace back to a short list of configuration, dependency, or server mismatches. This guide walks you through practical, prioritized steps to diagnose and fix the common causes so you can get your Teen Patti app back to a playable state.
Overview: Where things usually go wrong
When a purchased template shows “not working” behavior, issues typically come from one or more of the following:
- Missing or incorrect server endpoints / environment variables
- Outdated SDKs, Unity/Gradle/iOS build settings
- API keys, billing, or ad configuration not replaced
- Build-time minification or signing problems (ProGuard, R8, key signing)
- Permissions, entitlements, or platform-specific requirements
- Platform differences (emulator vs. real device) or network issues (SSL/CORS)
Quick checklist (try these first)
- Reproduce the issue and capture logs (adb logcat or Xcode console).
- Read the template README and developer notes—often the required server URL or seed data are documented.
- Replace placeholder API keys (AdMob, Firebase, Facebook, payment gateways).
- Confirm server is running and accessible from the client (curl the endpoint from a desktop).
- Build for a real device and test network calls—emulators can mask permission or certificate issues.
Step-by-step troubleshooting
1) Reproduce and collect evidence
Before changing anything, reproduce the problem and collect logs. For Android:
adb logcat -v time > logcat.txt
adb shell pm list packages | grep teen
For iOS, run the app from Xcode and watch the console. Capture crash traces, Unity stack traces, or JS errors if the project uses WebView/ReactNative. A clear error message (e.g., NullReferenceException, SSLHandshakeException) narrows your path quickly.
2) Confirm configuration and assets
Open config files (often named config.json, settings.plist, or in Unity as ScriptableObjects) and verify:
- API base URLs (production vs. development)
- App IDs and API keys are not the seller's placeholders
- Any required seed data or database setup steps were followed for the backend
Example: if the multiplayer server URL in config still points to the seller’s demo backend, the app will fail to join rooms or will show empty lobbies.
3) Backend & database checks
If the template ships with server-side code (Node, PHP, Laravel, Java, .NET), ensure:
- Dependencies are installed (npm install, composer install)
- Environment variables (.env) include correct DB credentials and API keys
- Database migrations and seeders were executed
- CORS and HTTPS are correctly configured
Test an endpoint with curl or Postman:
curl -I https://your-teengame.example.com/api/status
A 200 OK with a JSON status proves the server is up.
4) Dependency and SDK version mismatches
Templates are built against specific versions. If you import into a different Unity, Android Gradle Plugin, or iOS SDK version, runtime errors can occur. Check:
- Unity project version (open ProjectSettings/ProjectVersion.txt)
- Android Gradle Plugin and Gradle versions in build.gradle
- iOS deployment target and Swift version
Common solution: match the original build environment or follow the template author’s upgrade notes. If you must upgrade, do so incrementally and run tests at each step.
5) ProGuard / R8 / Code minification
If parts of the app crash only in release builds, minification is suspect. Temporarily disable minify to verify:
// in module build.gradle
minifyEnabled false
If the crash disappears, add keep rules for libraries or reflection-based classes used by the template. Check the README for required ProGuard rules—authors typically include them.
6) Permissions, entitlements, and platform policies
Mobile platforms require runtime permissions for camera, microphone, network, or storage. Missing runtime prompts cause features to silently fail. On Android, verify uses-permission in AndroidManifest and request at runtime. On iOS, ensure Info.plist includes usage descriptions (NSCameraUsageDescription, NSSpeechRecognitionUsageDescription, etc.).
7) Ads, analytics, and in-app purchases
Ad SDKs and in-app purchase flows often require proper account setup. Replace seller test IDs with your own. Use sandbox/test modes to validate the flows before going live. If the app shows black screens around ads or crashes when requesting an ad, ensure the SDKs are initialized with valid keys and the network is accessible.
8) SSL, certificate pinning, and CORS
Network issues are common. If your app fails on HTTPS calls:
- Check that the server certificate is valid and trusted on the device.
- If certificate pinning exists, update pins to the server’s cert.
- For web or hybrid components, ensure CORS headers allow your app’s origin.
Use openssl:
openssl s_client -showcerts -connect your-backend:443
9) Emulator vs. real device differences
Always test on a real device. Emulators may bypass certain hardware or permission behaviors. Network, sensors, and push notifications often behave differently on a real phone.
10) Clean builds and caching
Many issues vanish after a clean rebuild:
- Delete build caches, do a Clean and Rebuild.
- On Unity, delete Library and temp folders (with caution and backups).
- On Android, run ./gradlew clean and then assembleDebug/assembleRelease.
11) Multiplayer and real-time systems
For Teen Patti multiplayer, timing and network reliability matter. Verify:
- Game server is reachable and using compatible protocol (WebSocket, socket.io, UDP/TCP)
- Firewall or hosting provider isn’t blocking required ports
- Server tick rate and room-management logic match the client
Use websocket clients to test connectivity independent of the app:
wscat -c wss://your-game-server:port/path
12) When you need author or marketplace support
If you’ve exhausted local debugging, gather a concise bug report before contacting the template author or marketplace support. Include:
- Device model, OS version, and whether the problem is on emulator or real device
- Steps to reproduce and expected vs. actual behavior
- Relevant logs and screenshots/video
- Unity/Gradle/Xcode versions and a list of changes you made
Marketplace authors respond much faster with a clear, reproducible report.
Real examples and fixes I’ve applied
Example 1 — Crash on launch: The app crashed instantly with a NullReferenceException in a script that initializes Firebase. Fix: developer left a placeholder google-services.json in the Unity project. Replacing with a valid json for my Firebase project fixed startup.
Example 2 — Multiplayer lobby empty: The client showed no rooms. Investigation found the client was pointing to a demo endpoint that was down. Solution: update config to our hosted server URL and restart the server processes; added a health endpoint for future checks.
Example 3 — Ads cause freeze on iOS: Ad SDK was initialized before AppTrackingTransparency consent prompt, causing a deadlock on some iOS versions. Fix: request ATT permission first, then initialize the ad SDK in the completion handler.
Checklist to share with support (copy/paste)
- App version and build number
- Exact reproduction steps
- Platform: Android/iOS and device details
- Unity/SDK/Gradle/Xcode versions
- Log extracts (attach full logs as files)
- Network endpoints and whether they are reachable from my location
Resources and next steps
If the template specifically references Teen Patti external documentation or demo resources, consult the official site for gameplay rules, server integration notes, or assets. For quick reference you can check the demo resources here: keywords. If the marketplace copy or author mentions an external demo, verify the demo endpoints are still active.
When you contact the template seller, include the checklist above. If you are comfortable sharing logs or a reproducible minimal project, many authors will patch issues quickly. If you prefer to continue on your own, follow the prioritized steps: logs → config validation → dependency match → server checks → clean rebuild.
Finally, keep a short-lived staging environment for future testing and version control snapshots of working builds. That discipline reduces downtime and makes diagnosing regressions far easier.
Need help interpreting logs or want a second pair of eyes on your configuration? Share the core log excerpt and the exact message you see after following the steps above. If the issue is specific to the Teen Patti template server integration, you may also find useful resources at: keywords.
Good luck—most "not working" issues with purchased app templates are resolvable with systematic debugging. If you tell me the platform (Android or iOS), the error from your logs, and the Unity/SDK versions, I can suggest targeted next steps.
