26
27<p>The Android 1.1 system image delivered in the SDK is the development
28counterpart to the Android 1.1 production system image, deployable to
29Android-powered handsets starting in February 2009. </p>
30
31<p>The Android 1.1 system image delivers an updated version of the framework
32API. As with the Android 1.0 API, the Android 1.1 API
33is assigned an integer identifier &mdash; <strong>2</strong> &mdash; that is
34stored in the system itself. This identifier, called the "API Level", allows the
35system to correctly determine whether an application is compatible with
36the system, prior to installing the application. </p>
37
38<p>Applications indicate the lowest system API Level that they are compatible with by adding
39a value to the <code>android:minSdkVersion</code> attribute.
40The value of the attribute is an integer corresponding to an API Level
41identifier. Prior to installing an application, the system checks the value of
42<code>android:minSdkVersion</code> and allows the install only
43if the referenced integer is less than or equal to the API Level integer stored
44in the system itself. </p>
45
46<p>If you use the Android 1.1 system image to build an application
47compatible with Android-powered devices running the Android 1.1
48platform, you <strong style="color:red">must</strong> set the
49<code>android:minSdkVersion</code> attribute to "2" in order to specify that your application
50is compatible only with devices using the Android 1.1 (or greater) system image.
51</p>
52
53<p>Specifically, you specify the <code>android:minSdkVersion</code>
54attribute in a <code>&lt;uses-sdk&gt;</code> element as a child of
55<code>&lt;manifest&gt;</code> in the manifest file. When set, the
56attribute looks like this: </p>
57
58<pre><code>&lt;manifest&gt;
59  ...
60  &lt;uses-sdk android:minSdkVersion="2" /&gt;
61  ...
62&lt;/manifest&gt;</code>
63</pre>
64
65<p>By setting <code>android:minSdkVersion</code> in this way, you ensure
66that users will only be able to install your application if their
67devices are running the Android 1.1 platform. In turn, this ensures that
68your application will function properly on their devices, especially if
69it uses <a href="#apichange">APIs introduced in Android 1.1</a>. </p>
70
71<p>If your application uses APIs introduced in Android 1.1 but does not
72declare <code>&lt;uses-sdk android:minSdkVersion="2" /&gt;</code>, then it will
73run properly on Android 1.1 devices but <em>not</em> on Android 1.0
74devices. In the latter case, the application will crash at runtime when
75it tries to use the Android 1.1 APIs.</p>
76
77<p>If your application does not use any new APIs introduced in Android
781.1, you can indicate Android 1.0 compatibility by removing
79<code>android:minSdkVersion</code> or setting the attribute to "1". However,
80before publishing your application, you must make sure to compile your
81application against the Android 1.0 system image (available in the
82Android 1.0 SDK), to ensure that it builds and functions properly for
83Android 1.0 devices. You should test the application against system
84images corresponding to the API Levels that the application is designed
85to be compatible with.</p>
86
87<p>If you are sure your application is not using Android 1.1 APIs and
88has no need to use them, you might find it easier to keep working in the
89Android 1.0 SDK, rather than migrating to the Android 1.1 SDK and having
90to do additional testing.</p>
91
92
93<h2 id="extlibs">External Libraries</h2>
94
95<p>The system image includes these external libraries, which you can
96access from your application by adding a <a
97href="{@docRoot}guide/topics/manifest/uses-library-element.html">
98&lt;uses-library&gt;</a>.</p>
99	<ul>
100	<li>com.google.android.maps &mdash; gives your
101application access to Google Maps data. Note that, to use Google Maps
102data, a Maps API Key is required.</li>
103	</ul>
104
105<h2 id="comp">Device Compatibility</h2>
106
107<p>The Android 1.1 system image was tested for compatability with the
108Android-powered devices listed below:</p>
109	<ul>
110	<li>T-Mobile G1</li>
111	</ul>
112
113<h2 id="apps">Built-in Applications</h2>
114
115<p>The system image includes these built-in applications:</p>
116	<ul>
117	<li>Alarm Clock</li>
118	<li>API Demos</li>
119	<li>Browser</li>
120	<li>Calculator</li>
121	<li>Camera</li>
122	<li>Contacts</li>
123	<li>Dev Tools</li>
124	<li>Dialer</li>
125	<li>Email</li>
126	<li>Maps (and StreetView)</li>
127	<li>Messaging</li>
128	<li>Music</li>
129	<li>Pictures</li>
130	<li>Settings</li>
131	</ul>
132
133<h2 id="locs">UI Localizations</h2>
134
135<p>The system image provides localized UI strings for the languages
136listed below.</p>
137	<ul>
138	<li>English, US (en_US)</li>
139	<li>German (de) </li>
140	</ul>
141
142<p>Localized UI strings match the locales that are displayable in
143the emulator, accessible through the device Settings application.</p>
144
145<h2 id="resolved-issues">Resolved Issues</h2>
146<ul>
147<li>AlarmClock alert now plays audio/vibe directly, rather than through
148AlarmManager. AlarmClock alert starts playing audio/vibe in its
149IntentReceiver, rather than on activity start. These changes should
150prevent alarms from being blocked by modal dialogs.</li>
151<li>Fixes to device sleep. </li>
152<li>Single tap no longer opens the in-call dialpad; users now need to
153touch and drag it. </li>
154<li>Fixes a bug causing approximately 1 in 25 outbound messages to
155freeze up the IMAP connection (to a Gmail based server) when transferred
156to the Sent folder.</li>
157<li>Removes automatic account setup entries that were broken or not
158testable. Adds minor fixes to a few of the remaining entries. Makes
159improvements to warning dialogs used for a few special cases.	</li>
160<li>Changes default mail checking interval to every 15 minutes (instead
161of defaulting to "never").</li>
162<li>Fixes password-quoting bugs in IMAP, so that users can include
163special characters in passwords (e.g. spaces).</li>
164<li>Fixes various errors in auto and manual account setup	</li>
165<li>Improves reporting for various connection errors, making it easier
166for the user to diagnose failed account setups.</li>
167<li>Fixes new-mail notifications for POP3 accounts.</li>
168<li>Ensures proper auto-checking of accounts marked as "never
169check".</li>
170<li>Now displays date and time using user preference (e.g. 24 hr vs.
171AM/PM).</li>
172<li>Now shows cc: in message view.</li>
173<li>Improves recovery from POP3 connection failures.</li>
174<li>POP3 parser rules loosened, so the application can work with
175non-compliant email servers.</li>
176</ul>
177
178<h2 id="features">New Features</h2>
179
180<ul>
181<li>Maps: Adds details and reviews when a user does a search on Maps and
182clicks on a business to view its details.</li>
183<li>Dialer: In-call screen timeout default is now longer when using the
184speakerphone.</li>
185<li>Dialer: Adds a "Show dialpad" / "Hide dialpad" item to the in-call
186menu, to make it easier to discover the DTMF dialpad. </li>
187<li>Adds support for saving attachments from MMS</li>
188<li>Adds support for marquee in layouts.</li>
189</ul>
190
191<h2 id="api-changes">API Changes</h2>
192
193<h3>Overview</strong></h3>
194
195<ul>
