AndroidX - Program type already present: androidx.annotation.BoolRes

问题

I tried to migrate my current project today to AndroidX using the "Refactor - > Migrate to AndroidX" option in Android Studio and whenever I try to compile my application, I receive a

Program type already present: androidx.annotation.BoolRes

AGPBI: {"kind":"error","text":"Program type already present: androidx.annotation.BoolRes","sources":[{}],"tool":"D8"} :app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED :app:buildInfoGeneratorDebug FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

I used ./gradlew app:dependencies to fetch my list of dependencies, but it seems a lot of libraries are using the new androidx.annotation:annotation:1.0.0 dependency.

//Android
implementation "androidx.constraintlayout:constraintlayout:$constraintLayout"
implementation "androidx.cardview:cardview:$androidX"
implementation "androidx.recyclerview:recyclerview:$androidX"
implementation "androidx.annotation:annotation:1.0.0"

//Material
implementation "com.google.android.material:material:$material"

// ViewModel and LiveData
implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle"
annotationProcessor "androidx.lifecycle:lifecycle-compiler:$lifecycle"

//Room
implementation "androidx.room:room-runtime:$room"
annotationProcessor "androidx.room:room-compiler:$room"

The problem seems to be related to the renderscript api in my build.gradle file:

defaultConfig {
    applicationId "xxx"
    minSdkVersion 23
    targetSdkVersion 28
    versionCode versionMajor * 10000 + versionMinor * 100 + versionPatch
    versionName "${versionMajor}.${versionMinor}.${versionPatch}"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
    renderscriptTargetApi 28
    renderscriptSupportModeEnabled true
}

Removing the renderscriptSupportModeEnabled and renderscriptTargetApi from the block seems to fix the issue.

It doesn't happen to me during migration. But I run the app in debug mode and without stopping the debug, run the app without debug (Clicked the run app button in android studio).

I need to Clean the project (Build->Clean Project) to resolve this.

回答3:

implementation "androidx.annotation:annotation:1.0.0"

I think the problem is with this dependency, try to upgrade and check whether the problem is solved or not. You can try this if it works:-

androidx.annotation:annotation:1.0.0-alpha3

If it doesn't try to upgrade the dependency.

Just disable renderscriptSupportModeEnabled and you will get your code compiled. It is disabled by default so you can just remove the below line from your build.gradle file.

renderscriptSupportModeEnabled = true

Note: Above flag will be required if you gives support API level < 19.
