比來(lái)測(cè)試報(bào)了如許的問(wèn)題， 在版本覆蓋安裝的時(shí)刻會(huì)報(bào)如下crash, 實(shí)驗(yàn)一下不雅然，具體跟進(jìn)了一下，發(fā)明要必現(xiàn)該問(wèn)題是須要前提的：
1，4.0或者4.1體系
2，覆蓋前Activitystack 棧中有三個(gè)以上Activity
經(jīng)查很多同仁碰到了同樣的問(wèn)題，收集備忘于此。今朝沒(méi)有太好的解決辦法。在高版本體系上或者低版本膳綾腔有該種問(wèn)題。有在排查同樣問(wèn)題的兄弟們沒(méi)時(shí)光不要再去查了。意義不大年夜。
