當嘗試使用 C++ 使用內容中心開啟檔案時,我收到以下錯誤:
Opening with peer com.ubuntu.music_music_2.1.857
Sdk-Launcher> Application was resumed
Sdk-Launcher> There has been a AppArmor denial for your application.
Sdk-Launcher> Most likely it is missing a policy in the AppArmor file.

transfer state changed to 5
Sdk-Launcher> Application was focused
transfer state changed to 5
transfer state changed to 5
我檢查了 Transfer::State 枚舉,發現狀態 5 意味著中止。
這是我的 apparmor.json 檔案:
{
"policy_groups": [
"networking",
"content_exchange",
"content_exchange_source",
"audio"
],
"policy_version": 1.3
}
我正在使用 ubuntu-sdk-15.04-qml 框架。
在上次 OTA 更新之前,我的應用程式運作良好。在我的 Nexus 5 上,這是 r20。
任何幫助表示讚賞!
編輯:在嘗試解決此問題一段時間後,我注意到我可以從其他應用程式匯入內容,但匯出似乎仍然不起作用。
這是我的簡化導入程式碼(有效):
QPointer<cuc::Hub> hub = cuc::Hub::Client::instance();
cuc::Peer peer = hub->default_source_for_type(cuc::Type::Known::pictures());
cuc::Transfer * t = hub->create_import_from_peer(peers);
t->start();
這是我的簡化導出程式碼(不起作用):
QPointer<cuc::Hub> hub = cuc::Hub::Client::instance();
QVector<cuc::Peer> peers = hub->known_destinations_for_type(cuc::Type::Known::pictures());
cuc::Transfer * t = hub->create_export_to_peer(peers[0]);
QVector<cuc::Item> items;
items.append(cuc::Item(QUrl::fromLocalFile("/home/phablet/.local/share/com.nogzatalz.downow/download/Ed Sheeran – 5 (2015) (ALBUM) 320 KBPS/Cover.jpg")));
t->setSelectionType(cuc::Transfer::single);
t->charge(items);
答案1
在我的manifest.json中,我必須新增一個名為content-hub
hooks的屬性:
"content-hub": "hub.json"
然後創建一個hub.json
文件:
{
"source": [ "pictures" ]
}
