最近,我将Android Studio从1.5升级到2.0,但从那时起我发现错误和警告的数量有所增加.大多数错误没有意义.有人可以帮忙:

我是使用数字签名的新手.在其中一个项目中,我们使用Apache PdfBox处理数字签名的pdf文件.虽然我们可以测试所有功能,但验证已签名的pdf文件是我们无法破解的.我们使用BouncyCastle作为提供者.以下是代码:

//从pdf文件中获取数字签名和签名内容

byte[] signatureAsBytes = pdsignature.getContents(new FileInputStream(this.INPUT_FILE));
byte[] signedContentAsBytes = pdsignature.getSignedContent(new FileInputStream(this.INPUT_FILE));

//数字签名验证

Security.addProvider(new BouncyCastleProvider());
Signature signer = Signature.getInstance("RSA","BC");

//Get PublicKey from p7b file
X509Certificate cert509=null;
File file = new File("C:\\certificate_file.p7b");
FileInputStream fis = new FileInputStream(file);
CertificateFactory cf = CertificateFactory.getInstance("X.509");
Collection c = cf.generateCertificates(fis);
Iterator it = c.iterator();
PublicKey pubkey;

while (it.hasNext()) 
{
   cert509 = (X509Certificate) it.next();
   pubkey = cert509.getPublicKey();
}

boolean VERIFIED=false;
Security.addProvider(new BouncyCastleProvider());
Signature signer = Signature.getInstance("RSA","BC");
PublicKey key=this.getPublicKey(false);
signer.initVerify(key);

List<PDSignature> allsigs = this.PDFDOC.getSignatureDictionaries();

我正在开发一个服务帐户应用程序来获取访问下游服务的令牌。但是，我面临编译问题。Eclipse 提示错误“无法解析类型 com.google.api.client.auth.oauth2.Credential$Builder。它是从所需的 .class 文件间接引用的”。下面的代码片段：

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson.JacksonFactory;


public class AppMain {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    final HttpTransport TRANSPORT = new NetHttpTransport();
    final JsonFactory JSON_FACTORY = new JacksonFactory();

    GoogleCredential credential = new  GoogleCredential.Builder()
      .setTransport(TRANSPORT)
      .setJsonFactory(JSON_FACTORY)
      .setServiceAccountId("SOMETHING@developer.gserviceaccount.com")
      .setServiceAccountScopes(BigqueryScopes.BIGQUERY)
      .setServiceAccountPrivateKeyFromP12File(new File("key.p12"))
      .build();
}
}

请帮忙。提前致谢。
