1. Introduction​

⚠️ The following document contains different issues that can appear during the migration from SDK Mobile 1.4.X version to the SDK Mobile 2.0.X version. Depending on the developer application and its configuration.

2. Possible issues​

2.1 Upgrading compileSDKVersion​

Error​

Due to an older compileSDKVersion configuration, with this new version can appear this error:

Execution failed for task ':app:checkDebugAarMetadata'.
 
 A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   One or more issues found when checking AAR metadata values:
 
 Dependency 'androidx.navigation:navigation-common:2.7.7' requires 'compileSdkVersion' to be set to 34 or higher.
  
 Compilation target for module ':app' is 'android-33'

Dependency 'androidx.navigation:navigation-runtime:2.7.7' requires 'compileSdkVersion' to be set to 34 or higher.
  
Compilation target for module ':app' is 'android-33'
  
Dependency 'androidx.navigation:navigation-common-ktx:2.7.7' requires 'compileSdkVersion' to be set to 34 or higher.
  
Compilation target for module ':app' is 'android-33'

Solution​

Change in your application the minimum SDK version to 24:

defaultConfig {
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration. 
        minSdkVersion 24
        targetSdkVersion flutter.targetSdkVersion // targetSdkVersion 34
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

2.2 Upgrading Gradle Build Tools​

Error​

or

Solution​

In android/build.gradle file, change de gradle.build.tools to 7.4.0 or more:

 buildscript {
      ext.kotlin_version = '1.8.10'
      repositories {
          google()
          mavenCentral()
      }

      dependencies {
          classpath 'com.android.tools.build:gradle:7.4.0' // 7.4.0
          classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version'
      }
  }

In gradle-wrapper.properties file:

  distributionBase=GRADLE_USER_HOME
  distributionPath=wrapper/dists
  zipStoreBase=GRADLE_USER_HOME
  zipStorePath=wrapper/dists
  distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip // 7.5-all.zip

2.3 Changing result diagnostics​

Solution​

This parameter errorDiagnostic:

final SdkErrorType errorDiagnostic;

Now it’s an String in the 2.0.0 version:

final String errorDiagnostic;
