Android集成Google Photo Library遇NoSuchMethodError问题求助

我在Android应用中尝试获取并展示Google照片，使用以下代码但无法正常运行：

try {
    val credentialsStream : InputStream = resources.openRawResource(R.raw.credential)

    val credentials: GoogleCredentials =
        GoogleCredentials.fromStream(credentialsStream)
            .createScoped(Collections.singletonList("https://www.googleapis.com/auth/photoslibrary.readonly"))


    val settings = PhotosLibrarySettings.newBuilder()
        .setCredentialsProvider(FixedCredentialsProvider.create(credentials))
        .build()

    val photosLibraryClient: PhotosLibraryClient = PhotosLibraryClient.initialize(settings)

    val albums: MutableIterable<Album>? = photosLibraryClient.listAlbums().iterateAll()
    if (albums != null) {
        for (album in albums) {
            println("Album title: " + album.title)
            println("Album product URL: " + album.productUrl)
       
        }
    }

} catch (e: ApiException) {
    JLog.w("Error", "handleSignInResult:error: ${e.message}")
    e.printStackTrace()
}

使用的依赖库如下：

implementation ('io.grpc:grpc-okhttp:1.31.1') {
    exclude group: "com.squareup.okhttp"
}
implementation 'com.google.api-client:google-api-client-android:1.31.1'
implementation 'com.google.photos.library:google-photos-library-client:1.7.2'
implementation 'com.google.auth:google-auth-library-oauth2-http:1.7.0'

执行val photosLibraryClient: PhotosLibraryClient = PhotosLibraryClient.initialize(settings)时出现错误：

java.lang.NoSuchMethodError: No direct method (Ljava/lang/String;)V in class Lio/grpc/internal/AbstractManagedChannelImplBuilder; or its super classes (declaration of 'io.grpc.internal.AbstractManagedChannelImplBuilder' appears in /data/app/~~MOmfPzH0_A99g7RxMbRc7Q==/com.clicandprint-OwkMyEC4oLeBuyKNeMogtw==/base.apk!classes33.dex)

解决方案 #

这个错误源于grpc依赖版本不兼容：你手动指定的io.grpc:grpc-okhttp:1.31.1与Google Photos Library Client 1.7.2依赖的grpc版本存在方法签名差异，导致找不到对应方法。

方法一：移除手动指定的grpc依赖

让Photos Library Client自动引入兼容的grpc版本，修改后的依赖如下：

implementation 'com.google.api-client:google-api-client-android:1.31.1'
implementation 'com.google.photos.library:google-photos-library-client:1.7.2'
implementation 'com.google.auth:google-auth-library-oauth2-http:1.7.0'

方法二：统一grpc版本

如果必须手动管理grpc版本，需确保所有grpc相关组件版本一致。可以查看Photos Library Client 1.7.2的maven依赖树，找到它依赖的grpc版本，然后统一指定该版本的grpc组件。

额外注意事项 #

• 确认R.raw.credential对应的json文件是有效的Google Cloud服务账号凭据，且已在控制台启用Photos Library API
• 服务账号需要获得目标Google Photos账号的访问权限：如果是个人账号，需将相册共享给服务账号邮箱；如果是G Suite域账号，需配置域范围委派。
