PhoneGap的科爾多瓦2.0 onActivityResult不叫

我建立在PhoneGap的2.0應用程序使用修改WebIntent插件調用的意圖的形式應用。我可以在用戶成功發送到使用this.cordova.getActivity().startActivityForResult(intCanvas, 0);表單應用程序，但一旦用戶完成了活動，他們被傾倒出來到主屏幕，而不是返回到我的應用程序。PhoneGap的科爾多瓦2.0 onActivityResult不叫

你運行的內存？即使在這種情況下，您通常會被帶回Cordova，但州通常會丟失，您無法從您的活動中獲得結果。這種行爲在設備上是否一致？ –

不幸的是，我只能在ZTE Optik上測試它，因爲Canvas App我打算在最新的Android版本上使用Nexus 7的bug。日食LogCat或控制檯會顯示內存問題消息嗎？我沒有看到這樣的事情。 – LuckyStrike2021

是的，logcat會顯示。這是否在模擬器中做到這一點？我相信模擬器遠遠超過我相信中興通訊設備上發生的事情，這種情況有着不可預測的表演歷史。 –

因此，它與屏幕旋轉重新加載應用程序中的OLE問題。我只需要將android:configChanges="orientation" 添加到清單。不幸的是，如果每個人都沒有列出這個選項，就好像你可以在configChanges選項中有多個值一樣。

每一次這樣的錯誤了。 android:configChanges="orientation|keyboard"

this.cordova.getActivity().startActivityForResult(intCanvas, 0)

看到你對你的問題的答案..但一些原生的Android傢伙誰需要掛接到PhoneGap的可能想知道你可以得到你的活動，以回到你的插件是路確保：

this.cordova.setActivityResultCallback(MyActivity.this);

你做startActivityForResult()調用之前被調用。有些事情真的困擾着我，似乎沒有人回答。

這對Cordova 3.1和我的自定義插件有效 –
