Android 支付宝H5 没有回调

今天测试反馈问题，说，手机上没有安装支付宝的，调用支付宝支付之后，没有回调。不提示成功也不提示失败。

我自己试了半天也都是没有问题 。后来终于可以试出来了。

发现原来是，清单里面注册的Activity 不是在我调用的进程里面。

例子：

        <activity
            android:name="com.alipay.sdk.app.H5PayActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="portrait" />

因为我们的插件是在android:process=”@string/plug_process_name” 这个进程里面，所以，吊起来的H5是宿主的H5页面。（宿主程序也有自己的支付宝），所以，我们收不到结果。

改成：

        <activity
            android:name="com.alipay.sdk.app.H5PayActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:process="@string/plug_process_name"
            android:screenOrientation="portrait" />

就可以了。

看下堆栈吧：

自己搞了一天的时间。当然，我查到是收不到支付宝的回调，然后不再继续追查为什么收不到回调。说是支付宝的问题。但是，当我看到，自己的demo里面可以。那么，好奇心驱使我继续追查。也想过半路而费，这个棘手的问题，就是我的勋章。以后面试的时候，可以说了。
