第一就是配置:在項目的build.gradle裏面配置 先上圖,再上代碼。java
第二步,就是打包。(網上有介紹用命令打包,但是我這人太懶,發現了個小竅門,直接在android studio 裏面進行。)上圖(另外,後面我仍是補上了gradle命令打包的介紹。你們能夠看看http://my.oschina.net/aibenben/blog/370985)android
若是沒有keystore,先建立一個,默認爲.jks文件,同樣的。app
你們這裏建立完後,能夠再回頭看看前面配置的build.gradle裏面signingConfigs的內容。是否是就懂了(其實我這裏有一個疑問,感受若是用我這種方式去打包,簽名文件都沒有去讀取配置文件裏面的了)maven
你們能夠注意這裏的Flavors,先回頭看看前面配置的buld.gradle文件裏面的productFlavors,嘿嘿,渠道都在這了,按住ctrl,選擇你要打包的渠道,而後Finish.靜靜等待。須要要時間gradle
打包成功!點擊直接會進入到項目優化
打包好的apk,就在這了。ui
----固然,打包的過程當中,好多盆友可能會遇到一個錯誤.致使打包失敗。spa
Execution failed for task ':proguardGooglePlayRelease'.java.io.IOException: Can't write [D:\androidstudiocode\Demo4\build\intermediates\classes-proguard\GooglePlay\release\classes.jar] (Can't read [D:\androidstudiocode\Demo4\build\intermediates\exploded-aar\Demo4\appcompat_v7_8\unspecified\libs\android-support-v4.jar(;;;;;;!META-INF/MANIFEST.MF)] (Duplicate zip entry [android/support/v4/b/d.class == android-support-v4.jar:android/support/v4/os/ParcelableCompatCreatorHoneycombMR2.class])).net
是由於混淆打包的時候,有重複的v4包,因此你只須要刪掉一個,在Demo4這個項目裏面,我是直接註釋掉debug
再打包,等待,成功。
打包成功,咱們能夠驗證 Android 多渠道打包渠道驗證 .
最後直接貼上配置代碼
