“flutter build apk” for release in Flutter crashed when open the Apps

Question

I already set up for build app release like pro-guard, icon, manifest etc without flavor. I migrated dir /android to AndroidX because if not, failed to build app release when run flutter build apk. So I migrate it and success. Like below:

rifafauzi6@Anonymous-X456UR:/media/rifafauzi6/NM/Materi/BackUp Aplikasi Android/Flutter Project/vallery$ flutter build apk
You are building a fat APK that includes binaries for android-arm, android-arm64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64 --split-per-abi
        Learn more on:  https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split

Running Gradle task 'assembleRelease'... Done                      59.6s
Built build/app/outputs/apk/release/app-release.apk (16.1MB).

Then after success, I install it with two ways:

Using flutter install

rifafauzi6@Anonymous-X456UR:/media/rifafauzi6/NM/Materi/BackUp Aplikasi Android/Flutter Project/vallery$ flutter install

Installing build/app/outputs/apk/app.apk...                        16.4s

Using manual, go to that dir, and install it.

I already try flutter build apk --split-per-abi then like above I install it with two ways too. But still crashing when I open the app before showing the splash screen. This is the manifest for release apps in dir main:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="my_package">

    <!-- io.flutter.app.FlutterApplication is an android.app.Application that
         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->
    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="Vallery"
        android:usesCleartextTraffic="true"
        android:icon="@mipmap/ic_vallery">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- This keeps the window background of the activity showing
                 until Flutter renders its first frame. It can be removed if
                 there is no splash screen (such as the default splash screen
                 defined in @style/LaunchTheme). -->
            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

And this is the output of flutter doctor -v:

Can someone help me? Because I need to install it (release apk) first into real device before I upload to Play Store.

Answer 1

Try

flutter build apk --no-shrink

Update

flutter build apk --release --split-per-abi --no-shrink

This solved my problem
