It 76 * can be used with {@link Context#startActivity(Intent) startActivity} to 77 * launch an {@link android.app.Activity}, 78 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 79 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 80 * and {@link android.content.Context#startService} or 81 * {@link android.content.Context#bindService} to communicate with a 82 * background {@link android.app.Service}. 83 * 84 * <p>An Intent provides a facility for performing late runtime binding between the code in 85 * different applications. Its most significant use is in the launching of activities, where it 86 * can be thought of as the glue between activities. It is basically a passive data structure 87 * holding an abstract description of an action to be performed.</p> 88 * 89 * <div class="special reference"> 90 * <h3>Developer Guides</h3> 91 * <p>For information about how to create and resolve intents, read the 92 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 93 * developer guide.</p> 94 * </div> 95 * 96 * <a name="IntentStructure"></a> 97 * <h3>Intent Structure</h3> 98 * <p>The primary pieces of information in an intent are:</p> 99 * 100 * <ul> 101 * <li> <p><b>action</b> -- The general action to be performed, such as 102 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 103 * etc.</p> 104 * </li> 105 * <li> <p><b>data</b> -- The data to operate on, such as a person record 106 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 107 * </li> 108 * </ul> 109 * 110 * 111 * <p>Some examples of action/data pairs are:</p> 112 * 113 * <ul> 114 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 115 * information about the person whose identifier is "1".</p> 116 * </li> 117 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 118 * the phone dialer with the person filled in.</p> 119 * </li> 120 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 121 * the phone dialer with the given number filled in. Note how the 122 * VIEW action does what what is considered the most reasonable thing for 123 * a particular URI.</p> 124 * </li> 125 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 126 * the phone dialer with the given number filled in.</p> 127 * </li> 128 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 129 * information about the person whose identifier is "1".</p> 130 * </li> 131 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 132 * a list of people, which the user can browse through. This example is a 133 * typical top-level entry into the Contacts application, showing you the 134 * list of people. Selecting a particular person to view would result in a 135 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 136 * being used to start an activity to display that person.</p> 137 * </li> 138 * </ul> 139 * 140 * <p>In addition to these primary attributes, there are a number of secondary 141 * attributes that you can also include with an intent:</p> 142 * 143 * <ul> 144 * <li> <p><b>category</b> -- Gives additional information about the action 145 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 146 * appear in the Launcher as a top-level application, while 147 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 148 * of alternative actions the user can perform on a piece of data.</p> 149 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 150 * intent data. Normally the type is inferred from the data itself. 151 * By setting this attribute, you disable that evaluation and force 152 * an explicit type.</p> 153 * <li> <p><b>component</b> -- Specifies an explicit name of a component 154 * class to use for the intent. Normally this is determined by looking 155 * at the other information in the intent (the action, data/type, and 156 * categories) and matching that with a component that can handle it. 157 * If this attribute is set then none of the evaluation is performed, 158 * and this component is used exactly as is. By specifying this attribute, 159 * all of the other Intent attributes become optional.</p> 160 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 161 * This can be used to provide extended information to the component. 162 * For example, if we have a action to send an e-mail message, we could 163 * also include extra pieces of data here to supply a subject, body, 164 * etc.</p> 165 * </ul> 166 * 167 * <p>Here are some examples of other operations you can specify as intents 168 * using these additional parameters:</p> 169 * 170 * <ul> 171 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 172 * Launch the home screen.</p> 173 * </li> 174 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 175 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 176 * vnd.android.cursor.item/phone}</i></b> 177 * -- Display the list of people's phone numbers, allowing the user to 178 * browse through them and pick one and return it to the parent activity.</p> 179 * </li> 180 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 181 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 182 * -- Display all pickers for data that can be opened with 183 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 184 * allowing the user to pick one of them and then some data inside of it 185 * and returning the resulting URI to the caller. This can be used, 186 * for example, in an e-mail application to allow the user to pick some 187 * data to include as an attachment.</p> 188 * </li> 189 * </ul> 190 * 191 * <p>There are a variety of standard Intent action and category constants 192 * defined in the Intent class, but applications can also define their own. 193 * These strings use java style scoping, to ensure they are unique -- for 194 * example, the standard {@link #ACTION_VIEW} is called 195 * "android.intent.action.VIEW".</p> 196 * 197 * <p>Put together, the set of actions, data types, categories, and extra data 198 * defines a language for the system allowing for the expression of phrases 199 * such as "call john smith's cell". As applications are added to the system, 200 * they can extend this language by adding new actions, types, and categories, or 201 * they can modify the behavior of existing phrases by supplying their own 202 * activities that handle them.</p> 203 * 204 * <a name="IntentResolution"></a> 205 * <h3>Intent Resolution</h3> 206 * 207 * <p>There are two primary forms of intents you will use. 208 * 209 * <ul> 210 * <li> <p><b>Explicit Intents</b> have specified a component (via 211 * {@link #setComponent} or {@link #setClass}), which provides the exact 212 * class to be run. Often these will not include any other information, 213 * simply being a way for an application to launch various internal 214 * activities it has as the user interacts with the application. 215 * 216 * <li> <p><b>Implicit Intents</b> have not specified a component; 217 * instead, they must include enough information for the system to 218 * determine which of the available components is best to run for that 219 * intent. 220 * </ul> 221 * 222 * <p>When using implicit intents, given such an arbitrary intent we need to 223 * know what to do with it. This is handled by the process of <em>Intent 224 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 225 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 226 * more activities/receivers) that can handle it.</p> 227 * 228 * <p>The intent resolution mechanism basically revolves around matching an 229 * Intent against all of the <intent-filter> descriptions in the 230 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 231 * objects explicitly registered with {@link Context#registerReceiver}.) More 232 * details on this can be found in the documentation on the {@link 233 * IntentFilter} class.</p> 234 * 235 * <p>There are three pieces of information in the Intent that are used for 236 * resolution: the action, type, and category. Using this information, a query 237 * is done on the {@link PackageManager} for a component that can handle the 238 * intent. The appropriate component is determined based on the intent 239 * information supplied in the <code>AndroidManifest.xml</code> file as 240 * follows:</p> 241 * 242 * <ul> 243 * <li> <p>The <b>action</b>, if given, must be listed by the component as 244 * one it handles.</p> 245 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 246 * already supplied in the Intent. Like the action, if a type is 247 * included in the intent (either explicitly or implicitly in its 248 * data), then this must be listed by the component as one it handles.</p> 249 * <li> For data that is not a <code>content:</code> URI and where no explicit 250 * type is included in the Intent, instead the <b>scheme</b> of the 251 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 252 * considered. Again like the action, if we are matching a scheme it 253 * must be listed by the component as one it can handle. 254 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 255 * by the activity as categories it handles. That is, if you include 256 * the categories {@link #CATEGORY_LAUNCHER} and 257 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 258 * with an intent that lists <em>both</em> of those categories. 259 * Activities will very often need to support the 260 * {@link #CATEGORY_DEFAULT} so that they can be found by 261 * {@link Context#startActivity Context.startActivity()}.</p> 262 * </ul> 263 * 264 * <p>For example, consider the Note Pad sample application that 265 * allows user to browse through a list of notes data and view details about 266 * individual items. Text in italics indicate places were you would replace a 267 * name with one specific to your own package.</p> 268 * 269 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 270 * package="<i>com.android.notepad</i>"> 271 * <application android:icon="@drawable/app_notes" 272 * android:label="@string/app_name"> 273 * 274 * <provider class=".NotePadProvider" 275 * android:authorities="<i>com.google.provider.NotePad</i>" /> 276 * 277 * <activity class=".NotesList" android:label="@string/title_notes_list"> 278 * <intent-filter> 279 * <action android:name="android.intent.action.MAIN" /> 280 * <category android:name="android.intent.category.LAUNCHER" /> 281 * </intent-filter> 282 * <intent-filter> 283 * <action android:name="android.intent.action.VIEW" /> 284 * <action android:name="android.intent.action.EDIT" /> 285 * <action android:name="android.intent.action.PICK" /> 286 * <category android:name="android.intent.category.DEFAULT" /> 287 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 288 * </intent-filter> 289 * <intent-filter> 290 * <action android:name="android.intent.action.GET_CONTENT" /> 291 * <category android:name="android.intent.category.DEFAULT" /> 292 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 293 * </intent-filter> 294 * </activity> 295 * 296 * <activity class=".NoteEditor" android:label="@string/title_note"> 297 * <intent-filter android:label="@string/resolve_edit"> 298 * <action android:name="android.intent.action.VIEW" /> 299 * <action android:name="android.intent.action.EDIT" /> 300 * <category android:name="android.intent.category.DEFAULT" /> 301 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 302 * </intent-filter> 303 * 304 * <intent-filter> 305 * <action android:name="android.intent.action.INSERT" /> 306 * <category android:name="android.intent.category.DEFAULT" /> 307 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 308 * </intent-filter> 309 * 310 * </activity> 311 * 312 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 313 * android:theme="@android:style/Theme.Dialog"> 314 * <intent-filter android:label="@string/resolve_title"> 315 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 316 * <category android:name="android.intent.category.DEFAULT" /> 317 * <category android:name="android.intent.category.ALTERNATIVE" /> 318 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 319 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 320 * </intent-filter> 321 * </activity> 322 * 323 * </application> 324 * </manifest></pre> 325 * 326 * <p>The first activity, 327 * <code>com.android.notepad.NotesList</code>, serves as our main 328 * entry into the app. It can do three things as described by its three intent 329 * templates: 330 * <ol> 331 * <li><pre> 332 * <intent-filter> 333 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 334 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 335 * </intent-filter></pre> 336 * <p>This provides a top-level entry into the NotePad application: the standard 337 * MAIN action is a main entry point (not requiring any other information in 338 * the Intent), and the LAUNCHER category says that this entry point should be 339 * listed in the application launcher.</p> 340 * <li><pre> 341 * <intent-filter> 342 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 343 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 344 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 345 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 346 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 347 * </intent-filter></pre> 348 * <p>This declares the things that the activity can do on a directory of 349 * notes. The type being supported is given with the <type> tag, where 350 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 351 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 352 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 353 * The activity allows the user to view or edit the directory of data (via 354 * the VIEW and EDIT actions), or to pick a particular note and return it 355 * to the caller (via the PICK action). Note also the DEFAULT category 356 * supplied here: this is <em>required</em> for the 357 * {@link Context#startActivity Context.startActivity} method to resolve your 358 * activity when its component name is not explicitly specified.</p> 359 * <li><pre> 360 * <intent-filter> 361 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 362 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 363 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 364 * </intent-filter></pre> 365 * <p>This filter describes the ability return to the caller a note selected by 366 * the user without needing to know where it came from. The data type 367 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 368 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 369 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 370 * The GET_CONTENT action is similar to the PICK action, where the activity 371 * will return to its caller a piece of data selected by the user. Here, 372 * however, the caller specifies the type of data they desire instead of 373 * the type of data the user will be picking from.</p> 374 * </ol> 375 * 376 * <p>Given these capabilities, the following intents will resolve to the 377 * NotesList activity:</p> 378 * 379 * <ul> 380 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 381 * activities that can be used as top-level entry points into an 382 * application.</p> 383 * <li> <p><b>{ action=android.app.action.MAIN, 384 * category=android.app.category.LAUNCHER }</b> is the actual intent 385 * used by the Launcher to populate its top-level list.</p> 386 * <li> <p><b>{ action=android.intent.action.VIEW 387 * data=content://com.google.provider.NotePad/notes }</b> 388 * displays a list of all the notes under 389 * "content://com.google.provider.NotePad/notes", which 390 * the user can browse through and see the details on.</p> 391 * <li> <p><b>{ action=android.app.action.PICK 392 * data=content://com.google.provider.NotePad/notes }</b> 393 * provides a list of the notes under 394 * "content://com.google.provider.NotePad/notes", from which 395 * the user can pick a note whose data URL is returned back to the caller.</p> 396 * <li> <p><b>{ action=android.app.action.GET_CONTENT 397 * type=vnd.android.cursor.item/vnd.google.note }</b> 398 * is similar to the pick action, but allows the caller to specify the 399 * kind of data they want back so that the system can find the appropriate 400 * activity to pick something of that data type.</p> 401 * </ul> 402 * 403 * <p>The second activity, 404 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 405 * note entry and allows them to edit it. It can do two things as described 406 * by its two intent templates: 407 * <ol> 408 * <li><pre> 409 * <intent-filter android:label="@string/resolve_edit"> 410 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 411 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 412 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 413 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 414 * </intent-filter></pre> 415 * <p>The first, primary, purpose of this activity is to let the user interact 416 * with a single note, as decribed by the MIME type 417 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 418 * either VIEW a note or allow the user to EDIT it. Again we support the 419 * DEFAULT category to allow the activity to be launched without explicitly 420 * specifying its component.</p> 421 * <li><pre> 422 * <intent-filter> 423 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 424 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 425 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 426 * </intent-filter></pre> 427 * <p>The secondary use of this activity is to insert a new note entry into 428 * an existing directory of notes. This is used when the user creates a new 429 * note: the INSERT action is executed on the directory of notes, causing 430 * this activity to run and have the user create the new note data which 431 * it then adds to the content provider.</p> 432 * </ol> 433 * 434 * <p>Given these capabilities, the following intents will resolve to the 435 * NoteEditor activity:</p> 436 * 437 * <ul> 438 * <li> <p><b>{ action=android.intent.action.VIEW 439 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 440 * shows the user the content of note <var>{ID}</var>.</p> 441 * <li> <p><b>{ action=android.app.action.EDIT 442 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 443 * allows the user to edit the content of note <var>{ID}</var>.</p> 444 * <li> <p><b>{ action=android.app.action.INSERT 445 * data=content://com.google.provider.NotePad/notes }</b> 446 * creates a new, empty note in the notes list at 447 * "content://com.google.provider.NotePad/notes" 448 * and allows the user to edit it. If they keep their changes, the URI 449 * of the newly created note is returned to the caller.</p> 450 * </ul> 451 * 452 * <p>The last activity, 453 * <code>com.android.notepad.TitleEditor</code>, allows the user to 454 * edit the title of a note. This could be implemented as a class that the 455 * application directly invokes (by explicitly setting its component in 456 * the Intent), but here we show a way you can publish alternative 457 * operations on existing data:</p> 458 * 459 * <pre> 460 * <intent-filter android:label="@string/resolve_title"> 461 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 462 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 463 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 464 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 465 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 466 * </intent-filter></pre> 467 * 468 * <p>In the single intent template here, we 469 * have created our own private action called 470 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 471 * edit the title of a note. It must be invoked on a specific note 472 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 473 * view and edit actions, but here displays and edits the title contained 474 * in the note data. 475 * 476 * <p>In addition to supporting the default category as usual, our title editor 477 * also supports two other standard categories: ALTERNATIVE and 478 * SELECTED_ALTERNATIVE.
