This skill teaches how to diagnose CometChat Android integration problems systematically. It covers Gradle build errors, runtime crashes, rendering issues, and version compatibility.
---
Use this skill when
- "CometChat isn't working"
- "I'm getting a build error"
- "The chat screen is blank"
- "Messages aren't loading"
- Gradle sync failures
- Runtime crashes with CometChat in the stack trace
Do not use this skill when
- Setting up a new integration → use
cometchat-android-v5-core - Customizing appearance → use

1. Common issues
| Symptom | Likely cause | Fix |
|---|---|---|
Could not resolve com.cometchat:chat-uikit-android | Missing Maven repo | Add maven { url "https://dl.cloudsmith.io/public/cometchat/cometchat/maven/" } to repositories |
Duplicate class com.cometchat.* | Multiple CometChat versions | Check dependency tree: ./gradlew app:dependencies |
| Blank conversation list | Not logged in, or no conversations exist | Verify getLoggedInUser() != null. Send a test message from dashboard. |
CometChatException: ERR - Authentication null | init() not called or failed | Call init() before login(). Check isSDKInitialized(). |
CometChatException: appIdErr | App ID not set in UIKitSettings | Verify setAppId() in UIKitSettingsBuilder |
| Components show but no data | Login succeeded but wrong region | Verify region matches dashboard: "us", "eu", "in" |
ClassNotFoundException in release build | ProGuard stripping CometChat classes | Add -keep class com.cometchat.** { *; } to proguard-rules.pro |
UnsupportedOperationException: Failed to resolve attribute when inflating CometChat views | App theme inherits Theme.AppCompat.* or Theme.Material3.* — the kit's attrs are resolved against Material 2 (CometChatTheme.DayNight itself parents on Theme.MaterialComponents.DayNight.NoActionBar) | Change app theme parent to CometChatTheme.DayNight |
NetworkOnMainThreadException | Calling CometChat sync methods on main thread | Use callbacks (all CometChat methods are async) |
minSdkVersion 21 error | CometChat requires API 24+ | Set minSdkVersion 24 in build.gradle |
| Message list shows wrong messages | setUser()/setGroup() called with wrong object | Verify UID/GUID matches the intended conversation |
| Calling buttons not showing | Calling SDK not added | Add com.cometchat:calls-sdk-android:4.+ dependency |
java.lang.NoSuchMethodError | Version mismatch between UI Kit and Chat SDK | Use compatible versions — UI Kit 5.x requires Chat SDK 4.x |
---
2. Diagnostic steps
1. Check init: CometChatUIKit.isSDKInitialized() — must be true 2. Check login: CometChatUIKit.getLoggedInUser() — must not be null 3. Check Gradle: ./gradlew app:dependencies | grep cometchat — verify versions 4. Check manifest: Verify INTERNET permission 5. Check region: Must match dashboard exactly 6. Check logs: Filter logcat for CometChat tag
---
Hard rules
- Always check init + login first. 90% of "it's not working" issues are init/login failures.
- Never guess at the cause. Check logcat, check the dependency tree, check the dashboard.
- ProGuard is the #1 release-build issue. Always add keep rules before the first release build.
