Android Studio在更新版本時(shí)，會(huì)有讓選擇升級(jí)源，如下：

默認(rèn)情況下選擇的是Stable Channel

這幾個(gè)Channel的版本是有一些差異的；

在Android Studio下載官網(wǎng)上，有如下介紹：`

Android Studio's built-in update mechanism can be set to receive updates through any one of these 4 channels.

Canary: Bleeding edge, released about weekly. These are early previews released in order to obtain real-world feedback during development. The canary channel will always have the latest build, including updates to beta or stable releases. We recommend running canary builds side-by-side with a beta or stable installation.

Dev: Canary builds after a full round of internal testing get promoted into the Dev Channel.

Beta: Release candidates based on stable canary builds, released and updated to obtain feedback prior to the stable release. The beta channel will be updated with new stable builds until a new canary build goes to beta.

Stable: The official stable release, as available from the Android Developer site.

翻譯過(guò)來(lái)就是就是這個(gè)意思：

Android Studio內(nèi)置的更新機(jī)制被設(shè)置成為如下四個(gè)可選的版本：

Canary（金絲雀）：Bleeding Edge（一種最新的、因而也并非完美的技術(shù)）,大約周更。這是最早被發(fā)布的預(yù)覽版本，為了能夠在開發(fā)過(guò)程中獲得真實(shí)世界的反饋。金絲雀版本會(huì)一直擁有最新的版本包括beta、stable發(fā)布版的更新。我們建議在安裝金絲雀版本的同時(shí)再安裝一個(gè)beta版本或者stable版本。

Dev（開發(fā)版）：金絲雀版本在經(jīng)過(guò)完整的測(cè)試之后會(huì)被提升到Dev版本。

Beta（Beta版）：發(fā)布預(yù)選基于穩(wěn)定的金絲雀版本。被發(fā)布并更新以獲取反饋先于穩(wěn)定版本。Beta版本將與一個(gè)新的穩(wěn)定版本一起被更新，直到一個(gè)新的金絲雀版本被確定為Beta版本。

Stable（穩(wěn)定版）：從Android Developer網(wǎng)站上可獲得的穩(wěn)定版本。

各個(gè)版本下載地址：Canary,?Dev,?Beta,?Stable.

弄明白了它們的差異，然后就是根據(jù)自己的需要進(jìn)行選擇了。。。。
