您好我在我的应用程序中使用Google登录它工作正常但是每当我退出时我尝试了许多解决方案来退出但它对我不起作用，如果我再点击Google登录按钮，那么应用程序崩溃。< / p>
这是我的登录代码
empty现在我需要从其他活动注销使用此代码
用于退出

这种方法对我不起作用。 即使我明确了偏好并尝试使用谷歌进行新登录，然后应用程序崩溃。

答案 0 :(得分：3)
先检查空值
set.seed(1)
dfmaker <- function() {
setNames(
data.frame(
replicate(5, sample(c(NA, 300:500), 4, TRUE), FALSE)),
c('pn_ds_ms_fa_th_hrs','rn_ds_ms_wi_th_stu' ,'adn_ds_ms_wi_th_hrs','pn_ds_ms_wi_th_hrs' ,'rn_bsn_ds_ms_wi_th_hrs'))
}
d <- dfmaker()
library(dplyr)
d <- tbl_df(d)
grepl_vec_pattern = Vectorize(grepl, 'pattern')
calcterm = function(s) {
require(pryr)
s = as.character(s)
grepped_patterns = grepl_vec_pattern(s, pattern = c('_sp', '_su', '_fa', '_wi'))
stopifnot(any(rowSums(grepped_patterns) == 1)) # Ensure that there is exactly one match
reduce_to_colname_with_true = apply(grepped_patterns, 1, compose(names, which))
lut_table = c('_sp' = 'spring', '_su' = 'summer', '_fa' = 'fall', '_wi' = 'winter')
lut_table[reduce_to_colname_with_true]
}
select(d, matches("^pn_|^adn_|^bsn_"), -starts_with("rn_bsn")) %>% # all the pn, adn, bsn programs, for all information
select(contains("_hrs") ) %>% # takes out just the hours
gather(placement, hours) %>% # flip it!
group_by(placement) %>% # gather all the schools into a single observation (replicated placement values at this point)
summarise(sumHours = sum(hours, na.rm=T)) %>%
mutate(term = calcterm(placement))
并为Logout调用bellow方法
