Are you struggling with Gradle errors, build failures, or APK debugging issues in Flutter? You're not alone! Many developers face these problems when setting up their Flutter Android projects. Here’s a complete troubleshooting guide to fix them.
Common Issues & Fixes
1️⃣ Gradle Version Conflict (AGP Issues)
💡 Error:
"AGP version is incompatible with Java 21."
✅ Solution: Update android/build.gradle:
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:8.2.1'
}
}
---
2️⃣ Java Compatibility Issues
💡 Error:
"Java version is not supported for AGP"
✅ Solution: Downgrade to Java 17 by setting the correct JAVA_HOME.

✅ Solution: Run this command:
flutter doctor --android-licenses
and accept all licenses.

✅ Solution:
Make sure your minSdkVersion is at least 21.
