Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Start with the first specific error in the build output—not the final “build failed” line. Identify whether the failure happens during Gradle configuration, dependency resolution, compilation, resource or manifest processing, or a later task. Then check the project’s JDK and version compatibility before changing generated source code. The same diagnostic approach applies to AI-generated and hand-written Android projects; official documentation does not establish a separate error-frequency ranking for AI-generated code.
How to diagnose an Android build failure
- Capture the full error. In Android Studio’s Build output or the terminal log, find the first actionable message and note the Gradle task or sync step that failed. Record the module, build variant, file and line if shown. A later generic failure message may only report the consequence.
- Reproduce it with the project’s Gradle Wrapper. Run
./gradlewon macOS or Linux, orgradlew.baton Windows, followed by the failing task or another relevant task. The wrapper selects the Gradle distribution configured for this project; see Android’s build configuration guide. - Separate configuration failures from task failures. Gradle’s troubleshooting guide suggests running
gradle help: if the same problem remains, investigate build configuration; if it succeeds, focus on the requested task or its inputs. For an Android project, use its wrapper when reproducing the failure. See Gradle’s build troubleshooting guide. - Check the environment and version set. Compare the JDK used in Android Studio with the one used by the terminal, then check the JDK requirement for the project’s Android Gradle Plugin (AGP) version. Review the wrapper’s Gradle version, AGP, Kotlin or other compiler plugins, SDK settings and dependency versions together.
- Follow the error to its source. Inspect the dependency tree for resolution and duplicate-class errors; inspect the selected source set, resources or merged manifest when those are named; and use compiler diagnostics to trace missing symbols or type mismatches.
- Make the smallest relevant change, sync and rebuild. After editing build files, sync the Gradle project in Android Studio, then rerun the failing task. If a different error appears, treat it as the next diagnostic rather than assuming the first fix resolved every issue.
Fix JDK and Java-version mismatches
Android Studio and a terminal build can launch Gradle with different JDKs. Android Studio uses the configured Gradle JDK; terminal Gradle uses JAVA_HOME when it is set, otherwise Java found on PATH. Android Developers recommends using the same JDK for both settings for consistent results. Check the exact project configuration and the Android Java versions guide before changing Java versions.
For example, AGP 8.x requires JDK 17; an earlier JDK can produce an explicit requirement error. This example applies to that AGP generation, not every Android project. Choose a JDK that satisfies the project’s AGP requirement rather than assuming the newest JDK is automatically appropriate.
Also distinguish the JDK that launches Gradle from the Java toolchain used to compile Java source. A project can configure these separately. Pinning a toolchain can help keep local and CI compilation consistent when those environments would otherwise select different Java versions.

Resolve Gradle, plugin, SDK and compiler-plugin incompatibilities
An Android build is a set of interdependent components: the Gradle distribution, AGP, SDK platform and build tools, Java or Kotlin compiler, compiler plugins and libraries. A library may require a particular compileSdk or minSdk, a compatible Gradle plugin, or a code-generation tool such as KSP. Plausible-looking versions generated together may still be incompatible.
- Check the wrapper’s
distributionUrlto identify the Gradle distribution the project uses. - Compare the project’s exact Gradle, AGP, Kotlin/compiler-plugin and SDK versions against the applicable official release documentation.
- Change the component implicated by the error, then check whether its compatibility requirements affect the rest of the set.
Avoid replacing the wrapper or plugin with “latest” as a blind fix: one upgrade can require coordinated changes elsewhere. Android’s tool and library interdependencies guide explains why these compatibility relationships matter.

Fix unresolved dependencies and duplicate classes
When Gradle cannot resolve a dependency
For an error such as Could not resolve all files for configuration ':app:debugRuntimeClasspath', capture the full dependency coordinate, repository-related message and configuration name. Then inspect the resolved dependency tree to determine which declaration requests the dependency and whether conflicting versions or repositories are involved. Android’s dependency resolution guide provides steps for investigating these errors.
When a class is present more than once
An error such as Program type already present ... can mean that a library is included both directly and transitively, or as both a local binary and a remote dependency. Identify which declarations provide the repeated class, then remove the redundant dependency or binary. If modules resolve different versions of a library across compile and runtime classpaths, align the versions; where appropriate, a library module can expose its intended dependency through an api dependency. Avoid adding a substitute library until you know which dependency introduced the conflict.

Check compileSdk, minSdk and targetSdk separately
These settings answer different questions. compileSdk determines which Android APIs are available to source code during compilation. minSdk sets the lowest Android version the app supports at runtime, although a dependency can raise the effective minimum. targetSdk affects runtime behavior and is not a replacement for compileSdk. See Android’s build configuration guide and tool and library interdependencies guide.
If generated code references an API absent from the configured compile SDK, either update the SDK deliberately or change the code to use APIs available to the project. If compilation succeeds but the app calls a newer API on an older supported device, address runtime compatibility in the code; changing targetSdk or minSdk is not a general substitute. Check library requirements before raising minSdk, since that may narrow device support.

Investigate sync, variants, resources and manifest errors
Sync after build-file changes
After editing Gradle files, sync the project in Android Studio so the IDE imports the configuration and can report configuration errors. Pending build-file changes can also affect whether run configurations are available.
Check the variant that actually failed
A build variant combines source sets such as main, a build type, a product flavor and variant-specific directories. Higher-priority variant sources can override lower-priority ones. If only a debug, release or flavored build fails, verify which source files and resources that exact variant includes; a resource or class available in one variant may be absent in another.

Trace manifest merge conflicts
Android merges manifests from source sets and dependencies according to source-set priority. If the error names a manifest attribute, component or permission, open Android Studio’s merged-manifest view and identify which input contributes the conflicting declaration. Fix that input or use an appropriate merge directive. Adding permissions indiscriminately may not address the conflict. See Android’s manifest management guide.
Read compiler errors in generated source
If configuration and dependency resolution succeed but compilation fails, use the compiler’s named file, line, symbol and type diagnostics. Check whether generated code has a missing class, incorrect package, unavailable API, incompatible function signature or resource identifier that is absent from the selected source set. These are diagnostic possibilities, not an established ranking of AI-generated-code errors.
Correct the specific symbol, package or API mismatch. Add a dependency only when the missing symbol genuinely belongs to a library the app should use. If the compiler points to a resource, verify that the resource exists in the source set selected by the failing variant.
What to record before changing versions
Keep a short record of the exact failing phase, whether the error reproduces with the wrapper and in Android Studio, and the project’s Gradle, AGP, JDK, Kotlin/compiler-plugin and SDK versions. Note whether the proposed fix changes one source line, one dependency, shared versions or the toolchain, and whether it preserves the intended minimum Android version and build variant. This makes it easier to distinguish a targeted repair from a broad upgrade that introduces new compatibility problems.
