【中文标题】Android 上的 Google Ads API 客户端引发 ProviderNotFoundException【英文标题】:Google Ads API Client on Android throws ProviderNotFoundException 【发布时间】:2021-07-04 20:12:27 【问题描述】:如果我将 Google Ads API 与 Java 客户端库一起使用,则会引发以下异常:
io.grpc.ManagedChannelProvider$ProviderNotFoundException: No functional channel service provider found. Try adding a dependency on the grpc-okhttp, grpc-netty, or grpc-netty-shaded artifact

at com.google.ads.googleads.lib.catalog.GeneratedCatalog$V7Client.createGoogleAdsServiceClient(GeneratedCatalog.java:4948)
我不确定这是否与我使用客户端 API 的方式有关。我使用其他 Google API,其中一些使用 GoogleSignInAccount
,因此我从登录帐户中提取访问令牌:
Credentials credentials = OAuth2Credentials.newBuilder()
.setAccessToken(new AccessToken(
GoogleAuthUtil.getToken(mContext,
GoogleSignIn.getLastSignedInAccount(mContext).getAccount(),
"oauth2:" + scope)),
// Set expiration time in one hour, as credentials are created every time
// this method is called.
new Date(System.currentTimeMillis() + 60 * 60 * 1000))
.build();
GoogleAdsClient client = GoogleAdsClient.newBuilder()
.setCredentials(mAuthorizationService.getCredentials(SCOPE_ADWORDS))
.setDeveloperToken(mDeveloperToken)
.build();
String query = "SELECT metrics.cost_micros"
+ "FROM campaign "
+ "WHERE segments.date BETWEEN '" + getDate(start) + "' AND '" + getDate(end) + "' ";
SearchGoogleAdsRequest request = createRequest(client, query);
try (GoogleAdsServiceClient googleAdsService = createServiceClient(client))
GoogleAdsServiceClient.SearchPagedResponse response = googleAdsService.search(request);
最后一行是引发异常的地方。
【问题讨论】:
【参考方案1】:通过将以下内容添加到您的 gradle.build 文件中,可以“解决”该问题:
implementation 'io.grpc:grpc-okhttp:1.37.0'
为防止与 Google Ads API 库中包含的其他 gprc 库发生版本冲突,您应首先通过执行 gradlew app:dependencies
(在 android Studio 的终端视图中)检查版本并搜索其他库(例如 io.grpc:grpc-core
)。使用相同的版本而不是我的(所以将 1.37.0 替换为适当的版本)。
我已经举报了bug。
如果您遇到类似的构建错误
2 files found with path 'META-INF/io.netty.versions.properties'
添加
pickFirst 'META-INF/io.netty.versions.properties'
到您的 gradle.build 文件的 packagingOptions (并将名称替换为错误消息中的任何文件)。
