要解决“Android同步适配器 - 无法显式添加错误类型的账户。”的问题,以下是一个可能的解决方法,包含代码示例:
public class CustomAccountAuthenticator extends AbstractAccountAuthenticator {
public CustomAccountAuthenticator(Context context) {
super(context);
}
@Override
public Bundle addAccount(AccountAuthenticatorResponse response, String accountType, String authTokenType, String[] requiredFeatures, Bundle options) throws NetworkErrorException {
throw new UnsupportedOperationException("Cannot explicitly add account of this type.");
}
// 其他方法的实现...
}
public class MySyncAdapter extends AbstractThreadedSyncAdapter {
private final AccountManager accountManager;
public MySyncAdapter(Context context, boolean autoInitialize) {
super(context, autoInitialize);
accountManager = AccountManager.get(context);
}
@Override
public void onPerformSync(Account account, Bundle extras, String authority, ContentProviderClient provider, SyncResult syncResult) {
// 执行同步操作的逻辑...
}
// 在需要添加帐户的地方调用此方法
private void addAccount() {
Account account = new Account("account_name", "account_type");
boolean success = accountManager.addAccountExplicitly(account, null, null);
if (!success) {
throw new UnsupportedOperationException("Cannot add account of this type.");
}
// 其他逻辑...
}
}
通过这种方式,当尝试添加错误类型的帐户时,将抛出UnsupportedOperationException异常,并显示“Cannot explicitly add account of this type.”的错误信息。
