由于securityException导致java运行时异常

Question

我正在使用此代码创建帐户。但它抛出了安全异常。并且该帐户没有被创建

public static Account getSyncAccount(Context context) {
    AccountManager accountManager =(AccountManager) context.getSystemService(Context.ACCOUNT_SERVICE);
    Account newAccount = new Account(context.getString(R.string.app_name), context.getString(R.string.sync_account_type));

    if ( null == accountManager.getPassword(newAccount) ) {
        if (!accountManager.addAccountExplicitly(newAccount, "", null))
            return null;                     
       onAccountCreated(newAccount, context);
    }
    return newAccount;
}

logcat中的错误如下所示：

我在网上查了一下，但找不到解决办法。我做错了什么
