It 78 * can be used with {@link Context#startActivity(Intent) startActivity} to 79 * launch an {@link android.app.Activity}, 80 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 81 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 82 * and {@link android.content.Context#startService} or 83 * {@link android.content.Context#bindService} to communicate with a 84 * background {@link android.app.Service}. 85 * 86 * <p>An Intent provides a facility for performing late runtime binding between the code in 87 * different applications. Its most significant use is in the launching of activities, where it 88 * can be thought of as the glue between activities. It is basically a passive data structure 89 * holding an abstract description of an action to be performed.</p> 90 * 91 * <div class="special reference"> 92 * <h3>Developer Guides</h3> 93 * <p>For information about how to create and resolve intents, read the 94 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 95 * developer guide.</p> 96 * </div> 97 * 98 * <a name="IntentStructure"></a> 99 * <h3>Intent Structure</h3> 100 * <p>The primary pieces of information in an intent are:</p> 101 * 102 * <ul> 103 * <li> <p><b>action</b> -- The general action to be performed, such as 104 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 105 * etc.</p> 106 * </li> 107 * <li> <p><b>data</b> -- The data to operate on, such as a person record 108 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 109 * </li> 110 * </ul> 111 * 112 * 113 * <p>Some examples of action/data pairs are:</p> 114 * 115 * <ul> 116 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 117 * information about the person whose identifier is "1".</p> 118 * </li> 119 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 120 * the phone dialer with the person filled in.</p> 121 * </li> 122 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 123 * the phone dialer with the given number filled in. Note how the 124 * VIEW action does what is considered the most reasonable thing for 125 * a particular URI.</p> 126 * </li> 127 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 128 * the phone dialer with the given number filled in.</p> 129 * </li> 130 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 131 * information about the person whose identifier is "1".</p> 132 * </li> 133 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 134 * a list of people, which the user can browse through. This example is a 135 * typical top-level entry into the Contacts application, showing you the 136 * list of people. Selecting a particular person to view would result in a 137 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/people/N</i></b> } 138 * being used to start an activity to display that person.</p> 139 * </li> 140 * </ul> 141 * 142 * <p>In addition to these primary attributes, there are a number of secondary 143 * attributes that you can also include with an intent:</p> 144 * 145 * <ul> 146 * <li> <p><b>category</b> -- Gives additional information about the action 147 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 148 * appear in the Launcher as a top-level application, while 149 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 150 * of alternative actions the user can perform on a piece of data.</p> 151 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 152 * intent data. Normally the type is inferred from the data itself. 153 * By setting this attribute, you disable that evaluation and force 154 * an explicit type.</p> 155 * <li> <p><b>component</b> -- Specifies an explicit name of a component 156 * class to use for the intent. Normally this is determined by looking 157 * at the other information in the intent (the action, data/type, and 158 * categories) and matching that with a component that can handle it. 159 * If this attribute is set then none of the evaluation is performed, 160 * and this component is used exactly as is. By specifying this attribute, 161 * all of the other Intent attributes become optional.</p> 162 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 163 * This can be used to provide extended information to the component. 164 * For example, if we have a action to send an e-mail message, we could 165 * also include extra pieces of data here to supply a subject, body, 166 * etc.</p> 167 * </ul> 168 * 169 * <p>Here are some examples of other operations you can specify as intents 170 * using these additional parameters:</p> 171 * 172 * <ul> 173 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 174 * Launch the home screen.</p> 175 * </li> 176 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 177 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 178 * vnd.android.cursor.item/phone}</i></b> 179 * -- Display the list of people's phone numbers, allowing the user to 180 * browse through them and pick one and return it to the parent activity.</p> 181 * </li> 182 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 183 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 184 * -- Display all pickers for data that can be opened with 185 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 186 * allowing the user to pick one of them and then some data inside of it 187 * and returning the resulting URI to the caller. This can be used, 188 * for example, in an e-mail application to allow the user to pick some 189 * data to include as an attachment.</p> 190 * </li> 191 * </ul> 192 * 193 * <p>There are a variety of standard Intent action and category constants 194 * defined in the Intent class, but applications can also define their own. 195 * These strings use Java-style scoping, to ensure they are unique -- for 196 * example, the standard {@link #ACTION_VIEW} is called 197 * "android.intent.action.VIEW".</p> 198 * 199 * <p>Put together, the set of actions, data types, categories, and extra data 200 * defines a language for the system allowing for the expression of phrases 201 * such as "call john smith's cell". As applications are added to the system, 202 * they can extend this language by adding new actions, types, and categories, or 203 * they can modify the behavior of existing phrases by supplying their own 204 * activities that handle them.</p> 205 * 206 * <a name="IntentResolution"></a> 207 * <h3>Intent Resolution</h3> 208 * 209 * <p>There are two primary forms of intents you will use. 210 * 211 * <ul> 212 * <li> <p><b>Explicit Intents</b> have specified a component (via 213 * {@link #setComponent} or {@link #setClass}), which provides the exact 214 * class to be run. Often these will not include any other information, 215 * simply being a way for an application to launch various internal 216 * activities it has as the user interacts with the application. 217 * 218 * <li> <p><b>Implicit Intents</b> have not specified a component; 219 * instead, they must include enough information for the system to 220 * determine which of the available components is best to run for that 221 * intent. 222 * </ul> 223 * 224 * <p>When using implicit intents, given such an arbitrary intent we need to 225 * know what to do with it. This is handled by the process of <em>Intent 226 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 227 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 228 * more activities/receivers) that can handle it.</p> 229 * 230 * <p>The intent resolution mechanism basically revolves around matching an 231 * Intent against all of the <intent-filter> descriptions in the 232 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 233 * objects explicitly registered with {@link Context#registerReceiver}.) More 234 * details on this can be found in the documentation on the {@link 235 * IntentFilter} class.</p> 236 * 237 * <p>There are three pieces of information in the Intent that are used for 238 * resolution: the action, type, and category. Using this information, a query 239 * is done on the {@link PackageManager} for a component that can handle the 240 * intent. The appropriate component is determined based on the intent 241 * information supplied in the <code>AndroidManifest.xml</code> file as 242 * follows:</p> 243 * 244 * <ul> 245 * <li> <p>The <b>action</b>, if given, must be listed by the component as 246 * one it handles.</p> 247 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 248 * already supplied in the Intent. Like the action, if a type is 249 * included in the intent (either explicitly or implicitly in its 250 * data), then this must be listed by the component as one it handles.</p> 251 * <li> For data that is not a <code>content:</code> URI and where no explicit 252 * type is included in the Intent, instead the <b>scheme</b> of the 253 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 254 * considered. Again like the action, if we are matching a scheme it 255 * must be listed by the component as one it can handle. 256 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 257 * by the activity as categories it handles. That is, if you include 258 * the categories {@link #CATEGORY_LAUNCHER} and 259 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 260 * with an intent that lists <em>both</em> of those categories. 261 * Activities will very often need to support the 262 * {@link #CATEGORY_DEFAULT} so that they can be found by 263 * {@link Context#startActivity Context.startActivity()}.</p> 264 * </ul> 265 * 266 * <p>For example, consider the Note Pad sample application that 267 * allows user to browse through a list of notes data and view details about 268 * individual items. Text in italics indicate places were you would replace a 269 * name with one specific to your own package.</p> 270 * 271 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 272 * package="<i>com.android.notepad</i>"> 273 * <application android:icon="@drawable/app_notes" 274 * android:label="@string/app_name"> 275 * 276 * <provider class=".NotePadProvider" 277 * android:authorities="<i>com.google.provider.NotePad</i>" /> 278 * 279 * <activity class=".NotesList" android:label="@string/title_notes_list"> 280 * <intent-filter> 281 * <action android:name="android.intent.action.MAIN" /> 282 * <category android:name="android.intent.category.LAUNCHER" /> 283 * </intent-filter> 284 * <intent-filter> 285 * <action android:name="android.intent.action.VIEW" /> 286 * <action android:name="android.intent.action.EDIT" /> 287 * <action android:name="android.intent.action.PICK" /> 288 * <category android:name="android.intent.category.DEFAULT" /> 289 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 290 * </intent-filter> 291 * <intent-filter> 292 * <action android:name="android.intent.action.GET_CONTENT" /> 293 * <category android:name="android.intent.category.DEFAULT" /> 294 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 295 * </intent-filter> 296 * </activity> 297 * 298 * <activity class=".NoteEditor" android:label="@string/title_note"> 299 * <intent-filter android:label="@string/resolve_edit"> 300 * <action android:name="android.intent.action.VIEW" /> 301 * <action android:name="android.intent.action.EDIT" /> 302 * <category android:name="android.intent.category.DEFAULT" /> 303 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 304 * </intent-filter> 305 * 306 * <intent-filter> 307 * <action android:name="android.intent.action.INSERT" /> 308 * <category android:name="android.intent.category.DEFAULT" /> 309 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 310 * </intent-filter> 311 * 312 * </activity> 313 * 314 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 315 * android:theme="@android:style/Theme.Dialog"> 316 * <intent-filter android:label="@string/resolve_title"> 317 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 318 * <category android:name="android.intent.category.DEFAULT" /> 319 * <category android:name="android.intent.category.ALTERNATIVE" /> 320 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 321 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 322 * </intent-filter> 323 * </activity> 324 * 325 * </application> 326 * </manifest></pre> 327 * 328 * <p>The first activity, 329 * <code>com.android.notepad.NotesList</code>, serves as our main 330 * entry into the app. It can do three things as described by its three intent 331 * templates: 332 * <ol> 333 * <li><pre> 334 * <intent-filter> 335 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 336 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 337 * </intent-filter></pre> 338 * <p>This provides a top-level entry into the NotePad application: the standard 339 * MAIN action is a main entry point (not requiring any other information in 340 * the Intent), and the LAUNCHER category says that this entry point should be 341 * listed in the application launcher.</p> 342 * <li><pre> 343 * <intent-filter> 344 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 345 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 346 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 347 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 348 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 349 * </intent-filter></pre> 350 * <p>This declares the things that the activity can do on a directory of 351 * notes.

Note also the DEFAULT category 358 * supplied here: this is <em>required</em> for the 359 * {@link Context#startActivity Context.startActivity} method to resolve your 360 * activity when its component name is not explicitly specified.</p> 361 * <li><pre> 362 * <intent-filter> 363 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 364 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 365 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 366 * </intent-filter></pre> 367 * <p>This filter describes the ability to return to the caller a note selected by 368 * the user without needing to know where it came from. The data type 369 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 370 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 371 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 372 * The GET_CONTENT action is similar to the PICK action, where the activity 373 * will return to its caller a piece of data selected by the user. Here, 374 * however, the caller specifies the type of data they desire instead of 375 * the type of data the user will be picking from.</p> 376 * </ol> 377 * 378 * <p>Given these capabilities, the following intents will resolve to the 379 * NotesList activity:</p> 380 * 381 * <ul> 382 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 383 * activities that can be used as top-level entry points into an 384 * application.</p> 385 * <li> <p><b>{ action=android.app.action.MAIN, 386 * category=android.app.category.LAUNCHER }</b> is the actual intent 387 * used by the Launcher to populate its top-level list.</p> 388 * <li> <p><b>{ action=android.intent.action.VIEW 389 * data=content://com.google.provider.NotePad/notes }</b> 390 * displays a list of all the notes under 391 * "content://com.google.provider.NotePad/notes", which 392 * the user can browse through and see the details on.</p> 393 * <li> <p><b>{ action=android.app.action.PICK 394 * data=content://com.google.provider.NotePad/notes }</b> 395 * provides a list of the notes under 396 * "content://com.google.provider.NotePad/notes", from which 397 * the user can pick a note whose data URL is returned back to the caller.</p> 398 * <li> <p><b>{ action=android.app.action.GET_CONTENT 399 * type=vnd.android.cursor.item/vnd.google.note }</b> 400 * is similar to the pick action, but allows the caller to specify the 401 * kind of data they want back so that the system can find the appropriate 402 * activity to pick something of that data type.</p> 403 * </ul> 404 * 405 * <p>The second activity, 406 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 407 * note entry and allows them to edit it. It can do two things as described 408 * by its two intent templates: 409 * <ol> 410 * <li><pre> 411 * <intent-filter android:label="@string/resolve_edit"> 412 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 413 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 414 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 415 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 416 * </intent-filter></pre> 417 * <p>The first, primary, purpose of this activity is to let the user interact 418 * with a single note, as decribed by the MIME type 419 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 420 * either VIEW a note or allow the user to EDIT it. Again we support the 421 * DEFAULT category to allow the activity to be launched without explicitly 422 * specifying its component.</p> 423 * <li><pre> 424 * <intent-filter> 425 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 426 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 427 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 428 * </intent-filter></pre> 429 * <p>The secondary use of this activity is to insert a new note entry into 430 * an existing directory of notes. This is used when the user creates a new 431 * note: the INSERT action is executed on the directory of notes, causing 432 * this activity to run and have the user create the new note data which 433 * it then adds to the content provider.</p> 434 * </ol> 435 * 436 * <p>Given these capabilities, the following intents will resolve to the 437 * NoteEditor activity:</p> 438 * 439 * <ul> 440 * <li> <p><b>{ action=android.intent.action.VIEW 441 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 442 * shows the user the content of note <var>{ID}</var>.</p> 443 * <li> <p><b>{ action=android.app.action.EDIT 444 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 445 * allows the user to edit the content of note <var>{ID}</var>.</p> 446 * <li> <p><b>{ action=android.app.action.INSERT 447 * data=content://com.google.provider.NotePad/notes }</b> 448 * creates a new, empty note in the notes list at 449 * "content://com.google.provider.NotePad/notes" 450 * and allows the user to edit it. If they keep their changes, the URI 451 * of the newly created note is returned to the caller.</p> 452 * </ul> 453 * 454 * <p>The last activity, 455 * <code>com.android.notepad.TitleEditor</code>, allows the user to 456 * edit the title of a note. This could be implemented as a class that the 457 * application directly invokes (by explicitly setting its component in 458 * the Intent), but here we show a way you can publish alternative 459 * operations on existing data:</p> 460 * 461 * <pre> 462 * <intent-filter android:label="@string/resolve_title"> 463 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 464 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 465 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 466 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 467 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 468 * </intent-filter></pre> 469 * 470 * <p>In the single intent template here, we 471 * have created our own private action called 472 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 473 * edit the title of a note. It must be invoked on a specific note 474 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 475 * view and edit actions, but here displays and edits the title contained 476 * in the note data. 477 * 478 * <p>In addition to supporting the default category as usual, our title editor 479 * also supports two other standard categories: ALTERNATIVE and 480 * SELECTED_ALTERNATIVE.
