안드로이드 앱에서 사용자의 이메일 주소를 읽어오는 방법입니다.
회원가입시에 미리 입력 시켜둬서 사용자 편의성을 높이는데 사용할 수 있으며 악용하진 말아야할 것 입니다.
AccountManager를 이용하면 기기에 등록된 모든 계정이름을 불러올 수 있고 계정이름이 이메일인 경우가 많기 때문에 활용할 수 있습니다.
Pattern emailPattern = Patterns.EMAIL_ADDRESS; // API level 8+
Account[] accounts = AccountManager.get(context).getAccounts();
for (Account account : accounts) {
if (emailPattern.matcher(account.name).matches()) {
String possibleEmail = account.name;
...
}
} |
Pattern emailPattern = Patterns.EMAIL_ADDRESS; // API level 8+
Account[] accounts = AccountManager.get(context).getAccounts();
for (Account account : accounts) {
if (emailPattern.matcher(account.name).matches()) {
String possibleEmail = account.name;
...
}
}
AccountManager를 사용하려면 GET_ACCOUNTS 권한이 필요하니 AndroidManifest.xml에 권한을 추가해둬야 합니다.
<uses-permission android:name="android.permission.GET_ACCOUNTS" /> |
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
ICS부터는 사용자의 프로필에 접근하여 이메일을 가져올 수 있습니다.

READ_PROFILE과 READ_CONTACTS의 두 가지 권한이 필요합니다.
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" /> |
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
