我正在使用protobuf在我的Android客戶端中自動生成我的API服務，在gRPC技術中。自從我一直在努力解決問題以來，已經有好幾個月了。現在突然間，AndroidRuntime驗證程序正在拒絕我的API的自動生成方法之一。java.lang.VerifyError：驗證程序拒絕的類 - 未能驗證
這裏是堆棧跟蹤：
com.company.companyplayer E/AndroidRuntime: FATAL EXCEPTION: main

以下（解決方案類似的建議SO帖）沒有工作：
- 清潔和重新建立（甚至嘗試手動清洗）
- 的Invalidate緩存&重新啓動IDE 從原
- 重新生成API定義
另外，這裏是自動生成的方法在堆棧跟蹤中指出：
private void mergeNextDepositDate(com.google.protobuf.Timestamp value) {
if (nextDepositDate_ != null && nextDepositDate_ != com.google.protobuf.Timestamp.getDefaultInstance()) {
nextDepositDate_ = com.google.protobuf.Timestamp.newBuilder(nextDepositDate_).mergeFrom(value).buildPartial();
} else {
nextDepositDate_ = value;
}
}
它可以可以看出該方法既不是很長，也不需要太多的參數;有人說這是造成這個錯誤的常見原因。
以下是我的應用程序中的build.gradle：

（什麼都沒有的，因爲的gradle這一切工作正常，最後一次被改變）更新：該錯誤肯定與google.protobuf.Timestamp有關。這裏是link to an MWE，再現這個問題。
難道你得到充分的protobuf作爲一個依賴偶然？我假設你想使用protobuf lite。運行'./gradlew dependencies'並確保你只有com.google.protobuf：protobuf-lite依賴關係，而不是com.google.protobuf：protobuf-java –
@EricAnderson在我的gradle中有很多protobuf相關的條目，大多數其中一個'精簡版'。由於我不確定你說的是哪一個，所以我將我的build.gradle添加到上面的問題中。 –
