本文介绍如何使用Android中的AccountManager获取手机上的所有账号信息，并通过ContentResolver查询不同类型的Account支持的AUTHORITY，包括示例代码和所需权限。

android中的android.accounts.Account代表的是手机的基本账号信息（name和type）.

我们可以通过AccountManager取得Android手机的所有账号。

比如：

AccountManager am = AccountManager.get(context);

Account[] accounts = am.getAccounts();

然而每种type的Account支持的AUTHORITY（比如ContactsContract.AUTHORITY）并不尽相同。

我们可以通过ContentResolver.getSyncAdapterTypes()取得的SyncAdapterType来查询每种type的Account支持那些AUTHORITY。

示例程序：

void listAccount() {

Context context=HelloActivity.this;

AccountManager am = AccountManager.get(context);

Account[] accounts = am.getAccounts();

HashSet<String> contactAccountTypes = new HashSet<String>();

SyncAdapterType[] syncs = ContentResolver.getSyncAdapterTypes();

for (SyncAdapterType sync : syncs) {

Log.i(tag,"type:"+sync.accountType+" autohrity:"+sync.authority);

if (ContactsContract.AUTHORITY.equals(sync.authority)

&& sync.supportsUploading()) {

contactAccountTypes.add(sync.accountType);

}

ArrayList<Account> contactAccounts = new ArrayList<Account>();

for (Account acct : accounts) {

if (contactAccountTypes.contains(acct.type)) {

contactAccounts.add(acct);

}

for (Account ac : contactAccounts) {

Log.i(tag, "name:" + ac.name + " type:" + ac.type);

}

注意，需要android.permission.GET_ACCOUNTS权限。

运行打印的日志如下：
