我建立一个Android应用程序，其中用户将登录使用LinkedIn。如何在android中登录linkedin？

当用户点击按钮时，当我点击接受时输入电子邮件ID和密码后出现默认linkedin登录页面我禁用以获取用户详细信息。

下面是我的登录代码 -

public void onClick(View v) {

if (v.getId() == R.id.btnLinkedin) {

oAuthService = LinkedInOAuthServiceFactory.getInstance()

.createLinkedInOAuthService(Constants.CONSUMER_KEY,

Constants.CONSUMER_SECRET);

System.out.println("oAuthService : " + oAuthService);

factory = LinkedInApiClientFactory.newInstance(

Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);

liToken = oAuthService

.getOAuthRequestToken(Constants.OAUTH_CALLBACK_URL);

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(liToken

.getAuthorizationUrl()));

Toast.makeText(getApplicationContext(), "3", Toast.LENGTH_LONG).show();

startActivity(i);

}

}

@Override

protected void onNewIntent(Intent intent) {

super.onNewIntent(intent);

Toast.makeText(getApplicationContext(), "", Toast.LENGTH_LONG).show();

try {

linkedInImport(intent);

} catch (NullPointerException e) {

e.printStackTrace();

}

}

private void linkedInImport(Intent intent) {

String verifier = intent.getData().getQueryParameter("oauth_verifier");

System.out.println("liToken " + liToken);

System.out.println("verifier " + verifier);

LinkedInAccessToken accessToken = oAuthService.getOAuthAccessToken(

liToken, verifier);

client = factory.createLinkedInApiClient(accessToken);

// client.postNetworkUpdate("LinkedIn Android app test");

Person profile = client.getProfileForCurrentUser(EnumSet.of(

ProfileField.ID, ProfileField.FIRST_NAME,

ProfileField.LAST_NAME, ProfileField.HEADLINE));

System.out.println("First Name :: " + profile.getFirstName());

System.out.println("Last Name :: " + profile.getLastName());

System.out.println("Head Line :: " + profile.getHeadline());

}
