java - 如何获取 Android 用户的电子邮件地址？

Question

我有 android.permission.READ_OWNER_DATA 但我找不到任何可靠的代码来解释如何读取设备所有者的电子邮件地址。我该怎么做？

Answer 1

你为什么要这么做？

import android.accounts.Account;
import android.accounts.AccountManager;
import android.content.Context;

/**
 * This class uses the AccountManager to get the primary email address of the
 * current user.
 */
public class UserEmailFetcher {

  static String getEmail(Context context) {
    AccountManager accountManager = AccountManager.get(context); 
    Account account = getAccount(accountManager);

    if (account == null) {
      return null;
    } else {
      return account.name;
    }
  }

  private static Account getAccount(AccountManager accountManager) {
    Account[] accounts = accountManager.getAccountsByType("com.google");
    Account account;
    if (accounts.length > 0) {
      account = accounts[0];      
    } else {
      account = null;
    }
    return account;
  }
}

在您的 AnroidManifest.xml 中

<uses-permission android:name="android.permission.GET_ACCOUNTS" />
