It 55 * can be used with {@link Context#startActivity(Intent) startActivity} to 56 * launch an {@link android.app.Activity}, 57 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 58 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 59 * and {@link android.content.Context#startService} or 60 * {@link android.content.Context#bindService} to communicate with a 61 * background {@link android.app.Service}. 62 * 63 * <p>An Intent provides a facility for performing late runtime binding between the code in 64 * different applications. Its most significant use is in the launching of activities, where it 65 * can be thought of as the glue between activities. It is basically a passive data structure 66 * holding an abstract description of an action to be performed.</p> 67 * 68 * <div class="special reference"> 69 * <h3>Developer Guides</h3> 70 * <p>For information about how to create and resolve intents, read the 71 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 72 * developer guide.</p> 73 * </div> 74 * 75 * <a name="IntentStructure"></a> 76 * <h3>Intent Structure</h3> 77 * <p>The primary pieces of information in an intent are:</p> 78 * 79 * <ul> 80 * <li> <p><b>action</b> -- The general action to be performed, such as 81 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 82 * etc.</p> 83 * </li> 84 * <li> <p><b>data</b> -- The data to operate on, such as a person record 85 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 86 * </li> 87 * </ul> 88 * 89 * 90 * <p>Some examples of action/data pairs are:</p> 91 * 92 * <ul> 93 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 94 * information about the person whose identifier is "1".</p> 95 * </li> 96 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 97 * the phone dialer with the person filled in.</p> 98 * </li> 99 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 100 * the phone dialer with the given number filled in. Note how the 101 * VIEW action does what what is considered the most reasonable thing for 102 * a particular URI.</p> 103 * </li> 104 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 105 * the phone dialer with the given number filled in.</p> 106 * </li> 107 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 108 * information about the person whose identifier is "1".</p> 109 * </li> 110 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 111 * a list of people, which the user can browse through. This example is a 112 * typical top-level entry into the Contacts application, showing you the 113 * list of people. Selecting a particular person to view would result in a 114 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 115 * being used to start an activity to display that person.</p> 116 * </li> 117 * </ul> 118 * 119 * <p>In addition to these primary attributes, there are a number of secondary 120 * attributes that you can also include with an intent:</p> 121 * 122 * <ul> 123 * <li> <p><b>category</b> -- Gives additional information about the action 124 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 125 * appear in the Launcher as a top-level application, while 126 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 127 * of alternative actions the user can perform on a piece of data.</p> 128 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 129 * intent data. Normally the type is inferred from the data itself. 130 * By setting this attribute, you disable that evaluation and force 131 * an explicit type.</p> 132 * <li> <p><b>component</b> -- Specifies an explicit name of a component 133 * class to use for the intent. Normally this is determined by looking 134 * at the other information in the intent (the action, data/type, and 135 * categories) and matching that with a component that can handle it. 136 * If this attribute is set then none of the evaluation is performed, 137 * and this component is used exactly as is. By specifying this attribute, 138 * all of the other Intent attributes become optional.</p> 139 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 140 * This can be used to provide extended information to the component. 141 * For example, if we have a action to send an e-mail message, we could 142 * also include extra pieces of data here to supply a subject, body, 143 * etc.</p> 144 * </ul> 145 * 146 * <p>Here are some examples of other operations you can specify as intents 147 * using these additional parameters:</p> 148 * 149 * <ul> 150 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 151 * Launch the home screen.</p> 152 * </li> 153 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 154 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 155 * vnd.android.cursor.item/phone}</i></b> 156 * -- Display the list of people's phone numbers, allowing the user to 157 * browse through them and pick one and return it to the parent activity.</p> 158 * </li> 159 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 160 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 161 * -- Display all pickers for data that can be opened with 162 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 163 * allowing the user to pick one of them and then some data inside of it 164 * and returning the resulting URI to the caller. This can be used, 165 * for example, in an e-mail application to allow the user to pick some 166 * data to include as an attachment.</p> 167 * </li> 168 * </ul> 169 * 170 * <p>There are a variety of standard Intent action and category constants 171 * defined in the Intent class, but applications can also define their own. 172 * These strings use java style scoping, to ensure they are unique -- for 173 * example, the standard {@link #ACTION_VIEW} is called 174 * "android.intent.action.VIEW".</p> 175 * 176 * <p>Put together, the set of actions, data types, categories, and extra data 177 * defines a language for the system allowing for the expression of phrases 178 * such as "call john smith's cell". As applications are added to the system, 179 * they can extend this language by adding new actions, types, and categories, or 180 * they can modify the behavior of existing phrases by supplying their own 181 * activities that handle them.</p> 182 * 183 * <a name="IntentResolution"></a> 184 * <h3>Intent Resolution</h3> 185 * 186 * <p>There are two primary forms of intents you will use. 187 * 188 * <ul> 189 * <li> <p><b>Explicit Intents</b> have specified a component (via 190 * {@link #setComponent} or {@link #setClass}), which provides the exact 191 * class to be run. Often these will not include any other information, 192 * simply being a way for an application to launch various internal 193 * activities it has as the user interacts with the application. 194 * 195 * <li> <p><b>Implicit Intents</b> have not specified a component; 196 * instead, they must include enough information for the system to 197 * determine which of the available components is best to run for that 198 * intent. 199 * </ul> 200 * 201 * <p>When using implicit intents, given such an arbitrary intent we need to 202 * know what to do with it. This is handled by the process of <em>Intent 203 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 204 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 205 * more activities/receivers) that can handle it.</p> 206 * 207 * <p>The intent resolution mechanism basically revolves around matching an 208 * Intent against all of the <intent-filter> descriptions in the 209 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 210 * objects explicitly registered with {@link Context#registerReceiver}.) More 211 * details on this can be found in the documentation on the {@link 212 * IntentFilter} class.</p> 213 * 214 * <p>There are three pieces of information in the Intent that are used for 215 * resolution: the action, type, and category. Using this information, a query 216 * is done on the {@link PackageManager} for a component that can handle the 217 * intent. The appropriate component is determined based on the intent 218 * information supplied in the <code>AndroidManifest.xml</code> file as 219 * follows:</p> 220 * 221 * <ul> 222 * <li> <p>The <b>action</b>, if given, must be listed by the component as 223 * one it handles.</p> 224 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 225 * already supplied in the Intent. Like the action, if a type is 226 * included in the intent (either explicitly or implicitly in its 227 * data), then this must be listed by the component as one it handles.</p> 228 * <li> For data that is not a <code>content:</code> URI and where no explicit 229 * type is included in the Intent, instead the <b>scheme</b> of the 230 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 231 * considered. Again like the action, if we are matching a scheme it 232 * must be listed by the component as one it can handle. 233 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 234 * by the activity as categories it handles. That is, if you include 235 * the categories {@link #CATEGORY_LAUNCHER} and 236 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 237 * with an intent that lists <em>both</em> of those categories. 238 * Activities will very often need to support the 239 * {@link #CATEGORY_DEFAULT} so that they can be found by 240 * {@link Context#startActivity Context.startActivity()}.</p> 241 * </ul> 242 * 243 * <p>For example, consider the Note Pad sample application that 244 * allows user to browse through a list of notes data and view details about 245 * individual items. Text in italics indicate places were you would replace a 246 * name with one specific to your own package.</p> 247 * 248 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 249 * package="<i>com.android.notepad</i>"> 250 * <application android:icon="@drawable/app_notes" 251 * android:label="@string/app_name"> 252 * 253 * <provider class=".NotePadProvider" 254 * android:authorities="<i>com.google.provider.NotePad</i>" /> 255 * 256 * <activity class=".NotesList" android:label="@string/title_notes_list"> 257 * <intent-filter> 258 * <action android:name="android.intent.action.MAIN" /> 259 * <category android:name="android.intent.category.LAUNCHER" /> 260 * </intent-filter> 261 * <intent-filter> 262 * <action android:name="android.intent.action.VIEW" /> 263 * <action android:name="android.intent.action.EDIT" /> 264 * <action android:name="android.intent.action.PICK" /> 265 * <category android:name="android.intent.category.DEFAULT" /> 266 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 267 * </intent-filter> 268 * <intent-filter> 269 * <action android:name="android.intent.action.GET_CONTENT" /> 270 * <category android:name="android.intent.category.DEFAULT" /> 271 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 272 * </intent-filter> 273 * </activity> 274 * 275 * <activity class=".NoteEditor" android:label="@string/title_note"> 276 * <intent-filter android:label="@string/resolve_edit"> 277 * <action android:name="android.intent.action.VIEW" /> 278 * <action android:name="android.intent.action.EDIT" /> 279 * <category android:name="android.intent.category.DEFAULT" /> 280 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 281 * </intent-filter> 282 * 283 * <intent-filter> 284 * <action android:name="android.intent.action.INSERT" /> 285 * <category android:name="android.intent.category.DEFAULT" /> 286 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 287 * </intent-filter> 288 * 289 * </activity> 290 * 291 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 292 * android:theme="@android:style/Theme.Dialog"> 293 * <intent-filter android:label="@string/resolve_title"> 294 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 295 * <category android:name="android.intent.category.DEFAULT" /> 296 * <category android:name="android.intent.category.ALTERNATIVE" /> 297 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 298 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 299 * </intent-filter> 300 * </activity> 301 * 302 * </application> 303 * </manifest></pre> 304 * 305 * <p>The first activity, 306 * <code>com.android.notepad.NotesList</code>, serves as our main 307 * entry into the app. It can do three things as described by its three intent 308 * templates: 309 * <ol> 310 * <li><pre> 311 * <intent-filter> 312 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 313 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 314 * </intent-filter></pre> 315 * <p>This provides a top-level entry into the NotePad application: the standard 316 * MAIN action is a main entry point (not requiring any other information in 317 * the Intent), and the LAUNCHER category says that this entry point should be 318 * listed in the application launcher.</p> 319 * <li><pre> 320 * <intent-filter> 321 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 322 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 323 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 324 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 325 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 326 * </intent-filter></pre> 327 * <p>This declares the things that the activity can do on a directory of 328 * notes. The type being supported is given with the <type> tag, where 329 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 330 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 331 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 332 * The activity allows the user to view or edit the directory of data (via 333 * the VIEW and EDIT actions), or to pick a particular note and return it 334 * to the caller (via the PICK action). Note also the DEFAULT category 335 * supplied here: this is <em>required</em> for the 336 * {@link Context#startActivity Context.startActivity} method to resolve your 337 * activity when its component name is not explicitly specified.</p> 338 * <li><pre> 339 * <intent-filter> 340 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 341 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 342 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 343 * </intent-filter></pre> 344 * <p>This filter describes the ability return to the caller a note selected by 345 * the user without needing to know where it came from. The data type 346 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 347 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 348 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 349 * The GET_CONTENT action is similar to the PICK action, where the activity 350 * will return to its caller a piece of data selected by the user. Here, 351 * however, the caller specifies the type of data they desire instead of 352 * the type of data the user will be picking from.</p> 353 * </ol> 354 * 355 * <p>Given these capabilities, the following intents will resolve to the 356 * NotesList activity:</p> 357 * 358 * <ul> 359 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 360 * activities that can be used as top-level entry points into an 361 * application.</p> 362 * <li> <p><b>{ action=android.app.action.MAIN, 363 * category=android.app.category.LAUNCHER }</b> is the actual intent 364 * used by the Launcher to populate its top-level list.</p> 365 * <li> <p><b>{ action=android.intent.action.VIEW 366 * data=content://com.google.provider.NotePad/notes }</b> 367 * displays a list of all the notes under 368 * "content://com.google.provider.NotePad/notes", which 369 * the user can browse through and see the details on.</p> 370 * <li> <p><b>{ action=android.app.action.PICK 371 * data=content://com.google.provider.NotePad/notes }</b> 372 * provides a list of the notes under 373 * "content://com.google.provider.NotePad/notes", from which 374 * the user can pick a note whose data URL is returned back to the caller.</p> 375 * <li> <p><b>{ action=android.app.action.GET_CONTENT 376 * type=vnd.android.cursor.item/vnd.google.note }</b> 377 * is similar to the pick action, but allows the caller to specify the 378 * kind of data they want back so that the system can find the appropriate 379 * activity to pick something of that data type.</p> 380 * </ul> 381 * 382 * <p>The second activity, 383 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 384 * note entry and allows them to edit it. It can do two things as described 385 * by its two intent templates: 386 * <ol> 387 * <li><pre> 388 * <intent-filter android:label="@string/resolve_edit"> 389 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 390 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 391 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 392 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 393 * </intent-filter></pre> 394 * <p>The first, primary, purpose of this activity is to let the user interact 395 * with a single note, as decribed by the MIME type 396 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 397 * either VIEW a note or allow the user to EDIT it. Again we support the 398 * DEFAULT category to allow the activity to be launched without explicitly 399 * specifying its component.</p> 400 * <li><pre> 401 * <intent-filter> 402 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 403 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 404 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 405 * </intent-filter></pre> 406 * <p>The secondary use of this activity is to insert a new note entry into 407 * an existing directory of notes. This is used when the user creates a new 408 * note: the INSERT action is executed on the directory of notes, causing 409 * this activity to run and have the user create the new note data which 410 * it then adds to the content provider.</p> 411 * </ol> 412 * 413 * <p>Given these capabilities, the following intents will resolve to the 414 * NoteEditor activity:</p> 415 * 416 * <ul> 417 * <li> <p><b>{ action=android.intent.action.VIEW 418 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 419 * shows the user the content of note <var>{ID}</var>.</p> 420 * <li> <p><b>{ action=android.app.action.EDIT 421 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 422 * allows the user to edit the content of note <var>{ID}</var>.</p> 423 * <li> <p><b>{ action=android.app.action.INSERT 424 * data=content://com.google.provider.NotePad/notes }</b> 425 * creates a new, empty note in the notes list at 426 * "content://com.google.provider.NotePad/notes" 427 * and allows the user to edit it. If they keep their changes, the URI 428 * of the newly created note is returned to the caller.</p> 429 * </ul> 430 * 431 * <p>The last activity, 432 * <code>com.android.notepad.TitleEditor</code>, allows the user to 433 * edit the title of a note. This could be implemented as a class that the 434 * application directly invokes (by explicitly setting its component in 435 * the Intent), but here we show a way you can publish alternative 436 * operations on existing data:</p> 437 * 438 * <pre> 439 * <intent-filter android:label="@string/resolve_title"> 440 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 441 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 442 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 443 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 444 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 445 * </intent-filter></pre> 446 * 447 * <p>In the single intent template here, we 448 * have created our own private action called 449 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 450 * edit the title of a note. It must be invoked on a specific note 451 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 452 * view and edit actions, but here displays and edits the title contained 453 * in the note data. 454 * 455 * <p>In addition to supporting the default category as usual, our title editor 456 * also supports two other standard categories: ALTERNATIVE and 457 * SELECTED_ALTERNATIVE.
