專案升級TargetSDK 35問題紀錄

  • 預覽階段 (2024)

升級到target sdk 35 遇到gradle不相容

  • 這時候需要把gradle升級到8.0+ 才能解決，不過會遇到諸多問題...

Inconsistent JVM-target compatibility

target sdk 35
  • 解法1: 在gradle.properties加上
kotlin.jvm.target.validation.mode = IGNORE
  • 解法2: 參考Kid專案，在gradle.properties加上
COMPILE_JAVA_VERSION=17

並在對應的build.gradle指定java版本

target sdk 35

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

target sdk 35
  • 解法: 在gradle.properties加上
android.defaults.buildfeatures.buildconfig=true

AIDL error

target sdk 35
  • 解法: 在gradle.properties加上
android.defaults.buildfeatures.aidl=true

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

target sdk 35
  • 解法:
  1. In AirDroid/build.gradle, downgrade com.google.firebase:firebase-ads to 22.3.0
  2. In AdmobModule/build.gradle, downgrade com.google.android.gms:play-services-ads to 22.3.0
  • 參考: https://issuetracker.google.com/issues/327696048 https://stackoverflow.com/questions/78085458/manifest-merger-failed-with-agp-8-3-0 https://stackoverflow.com/questions/78350965/manifest-merger-failed-attribute-propertyandroid-adservices-ad-services-confi

AndroidAnnotation error

target sdk 35
  • 在gradle.properties加上
android.nonFinalResIds=false
  • 錯誤變成:
target sdk 35
  • AA(AndroidAnnotation)該建立的file都沒有建立成功。根據AA的debug方法，在build資料夾裡查看androidannotations.log:
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])
  • 發現是找不到AndroidManifest.xml file.
  • 參考其它專案，在AirDroid/Build.gradle裡加上:
javaCompileOptions {
    annotationProcessorOptions {
        arguments["androidManifestFile"] = "$projectDir/src/main/AndroidManifest.xml"
    }
}
  • AA該建立的file還是沒有建立成功。
  • 再次查看androidannotations.log:
10:25:09.812 [WorkerExecutor Queue] ERROR o.a.i.r.ProjectRClassFinder:49 - The generated .R class cannot be found

變成找不到.R檔。

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

成功通過compile! 但是開啟app會crash

Default FirebaseApp is not initialized

target sdk 35

  • Firebase會透過FirebaseInitProvider這個ContentProvider做自動初始化，不需要再額外自行加上FirebaseApp.initializeApp(Context)。

  • 觀察相關log:

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

發現初始化失敗。

  • 解法: 根目錄底下build.gradle，升級google-services至4.4.2
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.
  • 解法: 根目錄底下build.gradle，升級firebase-crashlytics至3.0.3
buildscript {
    dependencies {
        classpath 'com.google.firebase:firebase-crashlytics-gradle:3.0.3'
    }
}

Missing classes detected while running R8

  • channelRelease build failed 資訊:

  • 解法: 在AdmobModule的proguard-rules.pro裡加上:
-dontwarn java.lang.invoke.StringConcatFactory

AGP升級到8.0+ 時遇到GreenDao相容性問題

  • 雖然GreenDao停止更新了，github release最多也到3.3.0 但上去mvnrepository、跟github commit meesage查，greendaoPlugin在2023還有偷更新的紀錄。 實測把green dao plugin升級3.3.1之後就能通過sync project

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

  • 後面會再遇到另一個error

    target sdk 35 - 這時候把gradle中設定greendao的targetGenDir 改成`targetGenDir = file("$buildDir/generated/source/greendao")` target sdk 35 - 同時在kapt中加入對應的arguments ```kotlin kapt { correctErrorTypes = true 
        arguments {
        arg("greendao.targetGenDir", file("$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")
    }

}
```
