Fix: Firebase Auth sign-in does not persist in a Flutter Android release build

Firebase Auth restores the Android session from a private SharedPreferences file with no network call, so a release-only sign-out is never broken persistence. It is a different google-services.json, a rejected token refresh, App Check, or your own catch block.

Fix: Doesn't support required ABI when installing a .NET MAUI Android app

The APK has no native library for the device's CPU. Since .NET 9 the default Android RuntimeIdentifiers are 64-bit only, so the fix is to set RuntimeIdentifiers explicitly. Covers ADB0020, XA0036, NETSDK1083, the ABI to RID mapping, the Play Console wording, and why the four-RID snippet everyone copies breaks on .NET 11.

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.

Fix: Flutter UI overlaps the Android system navigation bar after targeting SDK 35

Targeting Android SDK 35 puts your Flutter app in edge-to-edge mode, so the Scaffold body draws behind the navigation bar. Consume the insets with SafeArea and MediaQuery padding instead of opting out, because the opt-out is already dead on Android 16.

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.

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.

Fix: flutter doctor reports cmdline-tools component is missing

Install the Android SDK Command-line Tools so the binaries land in <sdk>/cmdline-tools/latest/bin, point ANDROID_HOME at the SDK root, then re-run flutter doctor.

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.
