2026-08-22 errors flutter android

Fix: A restricted method in java.lang.System has been called in a Flutter Gradle build

The JEP 472 warning on JDK 24+ is harmless and prints once. Fix it by matching your JDK to a Gradle version that supports it, not by pasting flags into gradle.properties.

2026-08-21 errors flutter android

Fix: Toolchain installation does not provide the required capabilities: [JAVA_COMPILER]

Gradle is compiling with a JRE. It is not searching your machine, it is using the exact JVM it was launched on. Point flutter config --jdk-dir at a real JDK, or clear org.gradle.java.home.

2026-08-14 errors flutter android

Fix: An error occurred while preparing SDK package NDK (Side by side): Not in GZIP format

The SDK Manager is re-unpacking a corrupt archive it cached in .downloadIntermediates. Delete that folder and the half-extracted ndk/<version> directory, then re-run the build.

2026-08-14 errors flutter maui

Fix: Google Play rejects a Flutter or .NET MAUI app for missing 16 KB memory page size support

Play rejects the bundle because a 64-bit .so still has 4 KB ELF segments. Find the offending library, rebuild it with NDK r28+, and verify with zipalign -P 16.

2026-07-31 errors flutter android

Fix: Gradle task assembleDebug failed with exit code 1 in a Flutter Android build

That line is a wrapper, not the error. Re-run with flutter run --verbose or ./gradlew assembleDebug --stacktrace, read the real Gradle failure, then fix that.

2026-05-18 errors flutter android

Fix: AndroidX conflict during Flutter Android build

The fix in 30 seconds: set android.useAndroidX=true and android.enableJetifier=true in android/gradle.properties, then find any plugin still on the old support library and upgrade or replace it.

2026-05-18 errors flutter android

Fix: Flutter background_fetch plugin requires minSdkVersion 21

The fix in 30 seconds: set minSdkVersion to 21 (or higher) in android/app/build.gradle. background_fetch is built on Android's JobScheduler, which only exists from API 21.

2026-05-15 errors dotnet dotnet-11

Fix: Gradle build failed to produce an .apk file in MAUI Android

Nine out of ten times the real Gradle error is buried higher in the MSBuild log. JDK 17 path, missing maui-android workload, and Windows long paths are the usual root causes.
