kandi X-RAY | p2abcengine Summary

p2abcengine is a Java library typically used in Security, Authentication applications. p2abcengine has no bugs, it has no vulnerabilities and it has low support. However p2abcengine build file is not available. You can download it from GitHub.
This Privacy-Preserving Attribute-Based Credential Engine enables application developers to use Privacy-ABCs with all their features without having to consider the specifics of the underlying cryptographic algorithms, similar to as they do today for digital signatures, where they do not need to worry about the particulars of the RSA and DSA algorithms either. An introduction to the project and links to further information is found on the [wiki][wikihome]. The source code of the p2abcengine is licensed under the [Apache License, Version 2.0](https://github.com/p2abcengine/p2abcengine/blob/master/Code/LICENSE.txt). Note, however, that the p2abcengine depends on a number of Java libraries that are licensed under other licenses. For details, see the [overview of licenses of the library dependencies](https://github.com/p2abcengine/p2abcengine/blob/master/Code/LICENSES-OF-DEPENDENCIES.txt). The p2abcengine requires [IBM Identity Mixer](https://abc4trust.eu/idemix) as cryptographic engine. Identity Mixer is available under the [Identity Mixer License](https://abc4trust.eu/idemix).

QUESTION

Google API: java.lang.ClassNotFoundException: Didn't find class "sun.misc.Service"

Asked 2022-Apr-08 at 12:20

I've imported all necessary google dependencies for authenticate the user:

def play_services_version = "15.0.1"
implementation 'com.google.api-client:google-api-client:1.33.0'
implementation 'com.google.oauth-client:google-oauth-client-jetty:1.32.1'
implementation 'com.google.apis:google-api-services-drive:v3-rev20211107-1.32.1'
implementation 'com.sun.net.httpserver:http:20070405'
implementation 'com.google.android.gms:play-services-auth:16.0.0'
implementation "com.google.android.gms:play-services-auth:$play_services_version"
implementation "com.google.android.gms:play-services-drive:$play_services_version"
implementation 'com.squareup.okio:okio:1.14.0'

Receiving the user credetials.

/**
 * Creates an authorized Credential object.
 * @param HTTP_TRANSPORT The network HTTP Transport.
 * @return An authorized Credential object.
 * @throws IOException If the credentials.json file cannot be found.
 */
private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
    // Load client secrets.
    InputStream in = DriveQuickstart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
    if (in == null) {
        throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
    }
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));


    //Token Folder
    java.io.File s = new File(TOKENS_DIRECTORY_PATH);
    if(!s.exists()){
        boolean mkdir = s.mkdir();
    }
    File tokenFolder = new File(con.getFilesDir() +
            File.separator + TOKENS_DIRECTORY_PATH);
    if (!tokenFolder.exists()) {
        tokenFolder.mkdirs();
    }

    // Build flow and trigger user authorization request.
    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
            .setDataStoreFactory(new FileDataStoreFactory(tokenFolder))
            .setAccessType("offline")
            .build();

    LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();

    Credential credential = new AuthorizationCodeInstalledApp(flow,receiver ).authorize("user");
    //returns an authorized Credential object.
    return credential;
}

Since that Is official google documentation, the code should be on newest version, however executing the code, I receive Failed resolution of: Lsun/misc/Service Caused by: java.lang.ClassNotFoundException: Didn't find class "sun.misc.Service" error.

Is this due to missing dependencies or is that a bug from google?

The first sentence of the documentation that you linked to is: "Complete the steps described in the rest of this page to create a simple Java command-line application that makes requests to the Drive API." (emphasis added) Those instructions are not for Android.
