Gradle Compatibility Issues when Updating to target sdk 35

• To resolve this issue, you need to upgrade gradle to 8.0+, but various problems arise...

Inconsistent JVM-target compatibility

• Solution 1: Add the following to gradle.properties

kotlin.jvm.target.validation.mode = IGNORE

• Solution 2: Referring to the Kid project, add the following to gradle.properties

COMPILE_JAVA_VERSION=17

And specify the Java version in the corresponding build.gradle

Product Flavor 'global' contains custom BuildConfig fields, but the feature is disabled

• Solution: Add the following to gradle.properties

android.defaults.buildfeatures.buildconfig=true

AIDL error

• Solution: Add the following to gradle.properties

android.defaults.buildfeatures.aidl=true

Manifest merger failed : Attribute property#android.adservices.AD_SERVICES_CONFIG

• Solution:

1. Downgrade com.google.firebase:firebase-ads to 22.3.0 in AirDroid/build.gradle
2. Downgrade com.google.android.gms:play-services-ads to 22.3.0 in AdmobModule/build.gradle

AndroidAnnotation error

• Add the following to gradle.properties

android.nonFinalResIds=false

• Error changed to:

• The files that AA (AndroidAnnotation) should create are not being created properly. Following AA's debugging method, check androidannotations.log in the build folder:

10:13:18.48 [WorkerExecutor Queue Thread 2] ERROR o.a.i.h.AndroidManifestFinder:152 - Could not find the AndroidManifest.xml file, using  generation folder [/Users/sion/gerrit/airmirror/airdroid/AirDroid/build/generated/source/kapt/channelDebug])

• Found that the AndroidManifest.xml file could not be found.

• Referencing other projects, add the following to AirDroid/Build.gradle:

javaCompileOptions {
    annotationProcessorOptions {
        arguments["androidManifestFile"] = "$projectDir/src/main/AndroidManifest.xml"
    }
}

• The files that AA should create are still not being created properly.
• Check androidannotations.log again:

10:25:09.812 [WorkerExecutor Queue] ERROR o.a.i.r.ProjectRClassFinder:49 - The generated .R class cannot be found

The problem has changed to not finding the .R file.

• Change javaCompileOptions in AirDroid/Build.gradle as follows:

javaCompileOptions {
    annotationProcessorOptions {
        arguments = [
                'androidManifestFile': "$projectDir/src/main/AndroidManifest.xml",
                'resourcePackageName': getPackageName("sandstudio")
        ]
    }
}

Compilation succeeded! However, the app crashes when opened

Default FirebaseApp is not initialized

• Firebase performs auto-initialization through a ContentProvider called FirebaseInitProvider, so there's no need to separately add FirebaseApp.initializeApp(Context).

• Check related logs:

2025-02-13 15:12:46.078  4449-4449  FirebaseApp             com.sand.airmirror                   W  Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.
2025-02-13 15:12:46.078  4449-4449  FirebaseInitProvider    com.sand.airmirror                   I  FirebaseApp initialization unsuccessful

Found that initialization failed.

• Solution: Upgrade google-services to 4.4.2 in the root directory's build.gradle

buildscript {
    dependencies {
        classpath 'com.google.gms:google-services:4.4.2'
    }
}

Release build error while uploadCrashlyticsMappingFileIntlRelease

* What went wrong:
A problem was found with the configuration of task ':AirDroid:uploadCrashlyticsMappingFileIntlRelease' (type 'UploadMappingFileTask').
  - In plugin 'com.google.firebase.crashlytics' type 'com.google.firebase.crashlytics.buildtools.gradle.tasks.UploadMappingFileTask' property 'googleServicesFile' specifies file '/media/build/workspace/airmirror-release/AirDroid/build/generated/res/google-services/intl/release/values/values.xml' which doesn't exist.
    
    Reason: An input file was expected to be present but it doesn't exist.

• Solution: Upgrade firebase-crashlytics to 3.0.3 in the root directory's build.gradle

buildscript {
    dependencies {
        classpath 'com.google.firebase:firebase-crashlytics-gradle:3.0.3'
    }
}

GreenDao Compatibility Issues when Upgrading AGP to 8.0+

• GreenDao has stopped updating, and the releases on GitHub are at most 3.3.0, but checking mvnrepository and GitHub commit messages shows that greendaoPlugin was quietly updated in 2023. Actually upgrading green dao plugin to 3.3.1 makes sync project work.

  • https://mvnrepository.com/artifact/org.greenrobot/greendao-gradle-plugin
  • https://github.com/greenrobot/greenDAO/commit/1c45c2c581a5cd1dc2da025b3628d60dcf65bbed

• Later, another error occurs

  - In this case, change the targetGenDir in gradle's greendao settings to `targetGenDir = file("$buildDir/generated/source/greendao")` - Also add corresponding arguments to kapt ```kotlin kapt { correctErrorTypes = true

      arguments {
          arg("greendao.targetGenDir", file("$buildDir/generated/source/greendao").absolutePath)
          arg("greendao.schema", "$projectDir/src/main/java")
          arg("greendao.daoPackage", "com.sand.airsos.database")
          arg("greendao.targetGenDir", "$projectDir/src/main/java")
      }
  
  }
  ```
