為什麼安卓那麼多許可權

發布時間: 2023-08-08 21:45:25

1. 安卓手機裝APP時為什麼總會索取那麼多許可權呢

因為他們想獲得一些方面的信息,他們想獲取一些信息,所以讓你給他們那些許可權。

2. 為什麼android app需要獲取這些敏感許可權

為碼笑殲什麼android app需要獲取這些敏感許可權

上網有上網的許可權 讀寫sd卡有讀寫的許可權,你沒有許可權不想幹啥幹啥?

Android是Google開源的系統,又是因為是運行在手機上面的,如果沒有許可權讓用戶來管理的話,這個系統是不能再市場上使用的,主要是為安全著想。

常見的許可權不外乎定位,讀取聯系人,發送讀取簡訊。 因為app完整的的功能需要這些許可權。

6.0敏感許可權需要運行時獲取, 不獲取的話沒有許可權app會crash掉, 或者不能正常使用.

有一些是業務需求,比如裡麵包含掃碼功能,那麼必然需要攝像頭的許可權;一般的通訊社交軟體都會要求讀取通訊錄,以便推廣自己的應用或者方便你和通訊錄的好友一起互動;讀取手機設備升滲碼,是為了和你的手機做綁定保障唯一性和安全性。當然不排除一些惡意應用獲取這些許可權後,損害用戶利益。一般通過某些appStore下載的app,會有一定的安全保障,該應用市場會對app做一定的審查,不推薦直接安裝遲沖來歷不明的應用(包括某些從度獸搜索到的又不在網路市場的應用)。

3. 為什麼現在手機app需要這么多許可權,不給還不讓用。

盜取用戶個人信息,大多數的app根本用不上的許可權,強制要求用戶開啟,不開啟不給使用。這個就是Android系統開源的弊端。
正規的企業開發的app或許不會盜取用戶信息,但是小公司,不正規的app或許就會通過你的手機許可權盜取查看你的信息,上傳信息。
知道為什麼現在信息泄露那麼嚴重嗎
存儲許可權,每個app在下載到android的時候,就會在它的框架 裡面自動生成一個用以存儲緩存的空間,不需要開啟存儲空間也可以使用,卻被一些不法的app開發者鑽了空子,強制要求開啟存儲許可權,開啟以後,手機里的任意信息app都可以查看。沒有限制。
而一些壓根用不上相機許可權的app,卻要求攝像頭許可權,開啟以後,如果是不正規的軟體。app可以在你不知情的情況下任意使用攝像頭拍照,上傳。
通訊錄,很多APP都會要求通訊錄許可權,這就導致了自己的好友電話被開發者非法上傳,這也是為什麼手機號用久了會導致收到很多垃圾簡訊。
像強制用戶開啟許可權, 不給許可權不能用的app,最好不要使用,直接刪除。自己的手機,憑什麼app開發者要求怎麼樣,就怎麼樣
