最近公司專案需要新增支付功能，我們這邊主要整合支付寶和微信的支付。我這邊整合完支付寶後，發現了一個問題，就是我手機如果裝有支付寶的app，那麼可以呼叫起手機的app，但是解除安裝支付寶app後，卻呼叫不起來支付寶的H5頁面，於是本著學習的態度去網上查，查了一大堆資料，發現都是在AndroidManifest裡面加上

<activity
    android:name="com.alipay.sdk.app.H5PayActivity"
    android:configChanges="orientation|keyboardHidden|navigation|screenSize"
 
    android:exported="false"
    android:screenOrientation="behind"
    android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>

<activity
    android:name="com.alipay.sdk.app.H5AuthActivity"
 
    android:configChanges="orientation|keyboardHidden|navigation"
    android:exported="false"
    android:screenOrientation="behind"
    android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>

<activity
    android:name=
 
"com.alipay.sdk.app.H5PayActivity"
    android:configChanges="orientation|keyboardHidden|navigation|screenSize"
    android:exported="false"
    android:screenOrientation="behind"
    android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>

<activity
    android:name="com.alipay.sdk.app.H5AuthActivity"
    android:configChanges="orientation|keyboardHidden|navigation"
    android:exported="false"
    android:screenOrientation="behind"
    android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>

下面是支付寶的混淆：

-keep class com.alipay.android.app.IAlixPay{*;}
-keep class com.alipay.android.app.IAlixPay$Stub{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback$Stub{*;}
-keep class com.alipay.sdk.app.PayTask{ public *;}
-keep class com.alipay.sdk.app.AuthTask{ public *;}
-keep class com.alipay.sdk.app.H5PayCallback {
    <fields>;
    <methods>;
}
-keep class com.alipay.android.phone.mrpc.core.** { *; }
-keep class com.alipay.apmobilesecuritysdk.** { *; }
-keep class com.alipay.mobile.framework.service.annotation.** { *; }
-keep class com.alipay.mobilesecuritysdk.face.** { *; }
-keep class com.alipay.tscenter.biz.rpc.** { *; }
-keep class org.json.alipay.** { *; }
-keep class com.alipay.tscenter.** { *; }
-keep class com.ta.utdid2.** { *;}
-keep class com.ut.device.** { *;}

最後特別感謝：這位仁兄的對支付寶和微信的封裝，從而讓我可以輕易的呼叫！
