Are you a Flutter developer struggling to build an APK on your Mac ARM-based machine? You’re not alone! The “"flutter build apk" failing” error has been a thorn in the side of many developers, causing frustration and wasted hours. But fear not, dear reader, for we’ve got you covered. In this comprehensive guide, we’ll take you by the hand and walk you through the troubleshooting process, step by step, to get your APK building smoothly again.
Understanding the Error
Identifying the Error Message
When you run the command “flutter build apk” in your terminal, you might see an error message similar to the following:
FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:mergeReleaseResources'. > Error: Could not open zip file. * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. * Get more help at https://help.gradle.org
Take note of the error message, as it will give you a clue about what’s going wrong. In this example, the issue is related to the mergeReleaseResources task.
Troubleshooting Steps
Now that we’ve identified the error, let’s dive into the troubleshooting steps to resolve the “"flutter build apk" failing” issue on your Mac ARM-based machine.
Step 1: Update Your Flutter and Dart Versions
Outdated Flutter and Dart versions can cause compatibility issues. Make sure you’re running the latest versions:
flutter upgrade
Verify that you’re running the latest version:
flutter --version
Expected output:
Flutter 2.10.5 • channel stable • https://github.com/flutter/flutter.git Framework • revision 5464c5bac7 (3 weeks ago) • 2022-04-04 13:49:26 -0700 Engine • revision 62af7f6b5a Tools • Dart 2.16.2 • DevTools 2.9.2
Step 2: Check Your Java Installation
Java is a crucial dependency for the Gradle build process. Ensure you have Java 11 or later installed:
java --version
Expected output:
java 11.0.11 2021-04-20 Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.11+9, mixed mode)
If you don’t have Java 11 or later, download and install it from the official Oracle website.
Step 3: Fix Gradle Issues
Gradle is a key component of the APK build process. Sometimes, a simple clean and rebuild can resolve issues:
flutter clean flutter pub get flutter pub global run gradle build
If you’re still facing issues, try deleting the `.gradle` directory:
rm -rf ~/.gradle
Then, rebuild your project:
flutter pub global run gradle build
Step 4: Update Your `android/gradle/wrapper/gradle-wrapper.properties` File
The `gradle-wrapper.properties` file might be outdated or incompatible with your ARM-based machine. Update the file to use the latest Gradle version:
distributionUrl=https\://services.gradle.org/distributions/gradle-7.4.2-all.zip
Step 5: Add ARM Architecture Support
As ARM-based machines are relatively new, some libraries might not be optimized for ARM architecture. Add the following lines to your `android/app/build.gradle` file:
android {
...
defaultConfig {
...
ndk {
abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'
}
}
}
This will ensure that your APK builds with ARM architecture support.
Step 6: Verify Your `android/app/src/main/AndroidManifest.xml` File
The `AndroidManifest.xml` file might contain incorrect or outdated configuration. Verify that it’s correctly configured:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.your_app">
<application
android:name="io.flutter.app.FlutterApplication"
android:label="your_app"
android:icon="@mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
Common Issues and Solutions
In addition to the steps above, here are some common issues and their solutions:
The `android/app/build.gradle` File is Missing
If your project doesn’t have an `android/app/build.gradle` file, create a new one with the following content:
apply plugin: 'com.android.application'
android {
compileSdkVersion 30
defaultConfig {
applicationId "com.example.your_app"
minSdkVersion 21
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.3.1'
implementation 'com.google.android.material:material:1.4.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
The `android/app/src/main/res/values/styles.xml` File is Missing
If your project doesn’t have a `styles.xml` file, create a new one with the following content:
<resources>
<style name="LaunchTheme" parent="@android:style/Theme.Material.Light">
<item name="android:windowBackground">@drawable/launch_background</item>
</style>
</resources>

Frequently Asked QuestionStuck with the frustrating "flutter build apk" error on your Mac with an ARM-based chip? Worry not, friend! We’ve got you covered with these frequently asked questions and their solutions. Q1: Why does "flutter build apk" fail on my Mac with an ARM-based chip?The culprit behind this error is the lack of support for ARM architecture in the Android NDK. Flutter relies on the NDK to build APKs, and since ARM-based Macs aren’t supported, the build process fails. Don’t worry, we’ve got workarounds! Q2: Can I use Rosetta to emulate x86 architecture and fix the issue?You’re on the right track! Yes, you can use Rosetta to emulate x86 architecture, which might allow you to build the APK successfully. However, be aware that this might lead to performance issues and isn’t a foolproof solution. Keep reading for better alternatives! Q3: Is there a way to build an APK using an ARM-based emulator?You’re getting close! Yes, you can use an ARM-based emulator like ARM Emulator from Google or QEMU to build the APK. This approach requires some setup, but it’s a viable solution. Check out the official documentation for guidance! Q4: Can I use a cloud-based build service to avoid the ARM architecture issue?Genius idea! Yes, you can use cloud-based build services like Codemagic, Google Cloud Build, or CircleCI to build your APK. These services usually support x86 architecture, bypassing the ARM-based limitation. This approach might require some setup, but it’s a great way to avoid the hassle! Q5: Will the "flutter build apk" issue be fixed in future Flutter updates?The Flutter team is working on it! While there’s no official timeline, the community is actively discussing and working on solutions for ARM-based architecture support. Keep an eye on the Flutter issue tracker for updates, and fingers crossed, we’ll see a native solution soon! |
