The app crashes when opening image_cropper in release mode

Question

My app keeps crashing when I try to open image cropper in release mode.

I added everything in the manifest as directed in the documentation :

<activity
       android:name="com.yalantis.ucrop.UCropActivity"
       android:screenOrientation="portrait"
       android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

How I use it:

Future<void> _cropImage(File imageFile, int index) async {
if(imageFile != null){
  File cropped = await ImageCropper.cropImage(
      sourcePath: imageFile.path,
      aspectRatio: CropAspectRatio(ratioX: 1.0, ratioY: 1.0),
      compressQuality: 100,
      maxHeight: height,
      maxWidth: width,
      androidUiSettings: AndroidUiSettings(
        toolbarTitle: "",
        toolbarWidgetColor: Colors.black.withOpacity(0.6),
        statusBarColor: Colors.black,
        activeControlsWidgetColor: Colors.white,
      )
  );

  setState(() {
    compress(cropped, index);
  });
}}

As soon as I start the app in release mode, the following error message appears:

E/AndroidRuntime(13412): FATAL EXCEPTION: main

How can I fix this?. Thanks.

Answer 1

We will go through multiple solutions try them and tell me which one is your problem

1- in your build.gradle(Module: app) you will find this section remove it

if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "27.1.1"
}
if (details.requested.group == 'androidx.core'
&& !details.requested.name.contains('androidx') ) {
details.useVersion "1.0.1"
}
if (requested.group == "androidx") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "${targetSdk}.+"
}

2- Try adding the needed permissions to your manifest

<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

3- Try changing the gradle version into something like

classpath 'com.android.tools.build:gradle:3.6.3'

package/android/app/build.gradle

def localProperties = new Properties()
        def localPropertiesFile = rootProject.file('local.properties')
        if (localPropertiesFile.exists()) {
            localPropertiesFile.withReader('UTF-8') { reader ->
                localProperties.load(reader)
            }
        }
    
    def flutterRoot = localProperties.getProperty('flutter.sdk')
    if (flutterRoot == null) {
        throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
    }
    
    def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
    if (flutterVersionCode == null) {
        flutterVersionCode = '1'
    }
    
    def flutterVersionName = localProperties.getProperty('flutter.versionName')
    if (flutterVersionName == null) {
        flutterVersionName = '1.0'
    }

    apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
    
    def keystoreProperties = new Properties()
    def keystorePropertiesFile = rootProject.file('key.properties')
    if (keystorePropertiesFile.exists()) {
        keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
    }

android {
    compileSdkVersion 30

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

de

faultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.packages.xxx"
        minSdkVersion 24

            signingConfig signingConfigs.debug
        }
    }
}

        source '../..'
    }
    
    dependencies {

        implementation platform('com.google.firebase:firebase-bom:27.1.0')
        implementation 'com.google.firebase:firebase-analytics'
        implementation 'com.android.support:multidex:1.0.3'
    }

Answer 3

I was facing the same issue and below code, changes fixed it:

Add 'release' block inside the android in app/build.gradle file like give below

buildTypes {
        release {
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.debug
        }
    }

Create if not, 'app/proguard-rules.pro' file and add the following lines:

-dontwarn com.yalantis.ucrop**
-keep class com.yalantis.ucrop** { *; }
-keep interface com.yalantis.ucrop** { *; }
-keep class androidx.appcompat.** { *; }

After this release mode worked for me.

Answer 4

I had the same issue and it was because I only added the UCropActivity text into the AndroidManifest.xml within the Debug folder. It needed to be added to the AndroidManifest.xml within the Main folder as well for release to work.
