Android 用官方SDK實現第三方（qq、微信、微博等）分享和登入

阿新 • • 發佈：2019-02-18

上一篇講了android第三方登入，這一篇大概說一下分享。需要注意幾點：

1.登入和分享功能都必須是簽名之後的apk，才能用

2.再吐槽一下，微信SDK做的真他媽的變態，和登入一樣，必須是例如我的apk，包名（也就是AndroidManifest.xml中的包名）是com.kingdowin.gosu，你專案中必須有一個包名是com.kingdowin.gosu.wxapi，下面有一個類是WXEntryActivity.java，裡面寫登入或分享以及獲得返回響應結果（public void onResp(BaseResp resp) {}）微信程式碼，我不得不把自己的MainActivity改為WXEntryActivity。

否則就獲取不到使用者資訊，記好是必須的。只能說老大就是拽。

3.微信分享如果文字能分享而圖片不能，那是可能是因為你分享的圖片太大了，SDK協議中對縮圖的大小作了限制，大小不能超過32K（最好不要超過20k，因為在測試中有時27k就不能分享）。另外限制的還有title、description等引數的長度。另外Bitmap的compress方法不支援PNG，只支援JPG。

4.qq分享如果包含圖片似乎只支援手機裡的本地圖片而不支援二進位制

5、如果我們把WXEntryActivity設為

android:theme="@android:style/Theme.Translucent

作為透明的分享選單，那麼我們在Manifest中設定singleInstance，這樣從微信分享返回時才不會重複建立WXEntryActivity，並且呼叫onNewIntent()。

網上有許多說設為singleTop，這樣不對，因為微信肯定是在一個新的Task，我們可以getTaskId()來測試是不是taskId一樣。重新啟動

WXEntryActivity時，它也被放在那個新的Task，而singleTop只針對同一個task中，所以還會重新建立WXEntryActivity，這樣一來介面上就會產生許多個

WXEntryActivity，而這並不是我們想要的

 <activity
                android:name="com.yongche.wxapi.WXEntryActivity"
                android:exported="true"
                android:launchMode="singleInstance"
                android:screenOrientation="portrait"
                android:theme="@android:style/Theme.Translucent.NoTitleBar"
                >

6、問題：AndroidStudio做分享會報錯：

Error:Execution failed for task ':app:transformClassesWithMultidexlistForYongcheDebug'.

> java.io.IOException: Can't read [/Users/gaolei/Work/CompanyProject/android-weidao-driver/DriverZhuanche/app/build/intermediates/transforms/jarMerging/yongche/debug/jars/1/1f/combined.jar] (Can't process class [com/tencent/wxop/stat/al.class] (Unknown verification type [95] in stack map frame))

解決辦法：去微信開放平臺，下載最新的libammsdk.jar，就OK ^~^
