|
10 Service API</a> allows <span>widgets</span> to access and launch applications |
|
11 on a device. You can use the AppManager Service to create <span>widgets</span> that:</p> |
|
12 <ul> |
|
13 <li><p>Retrieve a list of user-installed applications</p></li> |
|
14 <li><p>Retrieve a list of all applications on the mobile device, |
|
15 regardless of whether they were preinstalled or installed by the user</p> |
|
16 </li> |
|
17 <li><p>Launch an application based on an application UID</p> |
|
18 </li> |
|
19 <li><p>Launch an application based on a given document or MIME type</p> |
|
20 </li> |
|
21 </ul> |
|
22 <p>The service allows <span>widgets</span> to launch applications as chained |
|
23 (embedded) or stand-alone. This provides the following functionality:</p> |
|
24 <ul> |
|
25 <li><p>Embedded applications are launched within another application |
|
26 and share the same process. All UI features (such as the options list and |
|
27 icons displayed in the header) belong to the launching application, not the |
|
28 embedded application. For example, embedding the browser to display HTML within |
|
29 an SMS message is a typical use case. In this case, all UI features belong |
|
30 to the messaging application.</p></li> |
|
31 <li><p>Stand-alone applications are independent of other applications |
|
32 - they do not share the same process. Applications can launch other applications |
|
33 as stand-alone, in which case they run as peer applications. For example, |
|
34 launching the browser when a user selects a URL within an SMS message is a |
|
35 typical use case. In this case, the user can swap between the browser and |
|
36 messaging applications.</p></li> |

39 <p>To create a <a href="GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080.html#GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080">service |
|
40 object</a> for the AppManager Service API, use <code>Service.AppManager</code> to |
|
41 identify the service provider and <code>IAppManager</code> to identify |
|
42 the supported interface:</p> |
|
43 |
|
44 <pre class="codeblock" id="GUID-A2F3BA97-7375-4A1A-82EB-B7D0CCFDBB63-GENIDd0e6831">var so = device.getServiceObject("Service.AppManager", "IAppManager");</pre> |
|
45 <p>The <code>IAppManager</code> interface provides the following |
|
46 methods:</p> |
|
47 <ul> |
|
48 <li><p><a href="GUID-4A2480A8-4D79-4F5D-9614-74A8934B8952.html#GUID-4A2480A8-4D79-4F5D-9614-74A8934B8952"><code>GetList()</code></a></p> |
|
49 |
|
50 <p>Use the <code>GetList()</code> method to get a list of user-installed |
|
51 applications or all applications on the mobile device.</p> |
|
52 |
|
53 </li> |
|
54 <li><p><a href="GUID-697AFF1F-24C7-43BD-A072-8352B3BE973C.html#GUID-697AFF1F-24C7-43BD-A072-8352B3BE973C"><code>LaunchApp()</code></a></p> |
|
55 |
|
56 <p>Use the <code>LaunchApp()</code> method to launch |
|
57 an application based on the application UID. Use <code>GetList()</code> to |
|
58 retrieve the correct UID.</p> |
|
59 |
|
60 </li> |
|
61 <li><p><a href="GUID-41FAD7DA-0DB7-48E7-BD60-58D6BFD785DA.html#GUID-41FAD7DA-0DB7-48E7-BD60-58D6BFD785DA"><code>LaunchDoc()</code></a></p> |
|
62 |
|
63 <p>Use the <code>LaunchDoc()</code> method to launch an application |
|
64 based on a given document or a MIME type.</p> |
|
65 |
|
66 </li> |
|
67 <li><p><a href="GUID-64CC3AB4-5444-474A-9470-818F423C5611.html#GUID-64CC3AB4-5444-474A-9470-818F423C5611"><code>Cancel()</code></a></p> |
|
68 |

69 <p>Use the <code>Cancel()</code> method to cancel an ongoing asynchronous |

|
71 Service API.</p> |
