It 75 * can be used with {@link Context#startActivity(Intent) startActivity} to 76 * launch an {@link android.app.Activity}, 77 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 78 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 79 * and {@link android.content.Context#startService} or 80 * {@link android.content.Context#bindService} to communicate with a 81 * background {@link android.app.Service}. 82 * 83 * <p>An Intent provides a facility for performing late runtime binding between the code in 84 * different applications. Its most significant use is in the launching of activities, where it 85 * can be thought of as the glue between activities. It is basically a passive data structure 86 * holding an abstract description of an action to be performed.</p> 87 * 88 * <div class="special reference"> 89 * <h3>Developer Guides</h3> 90 * <p>For information about how to create and resolve intents, read the 91 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 92 * developer guide.</p> 93 * </div> 94 * 95 * <a name="IntentStructure"></a> 96 * <h3>Intent Structure</h3> 97 * <p>The primary pieces of information in an intent are:</p> 98 * 99 * <ul> 100 * <li> <p><b>action</b> -- The general action to be performed, such as 101 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 102 * etc.</p> 103 * </li> 104 * <li> <p><b>data</b> -- The data to operate on, such as a person record 105 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 106 * </li> 107 * </ul> 108 * 109 * 110 * <p>Some examples of action/data pairs are:</p> 111 * 112 * <ul> 113 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 114 * information about the person whose identifier is "1".</p> 115 * </li> 116 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 117 * the phone dialer with the person filled in.</p> 118 * </li> 119 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 120 * the phone dialer with the given number filled in. Note how the 121 * VIEW action does what what is considered the most reasonable thing for 122 * a particular URI.</p> 123 * </li> 124 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 125 * the phone dialer with the given number filled in.</p> 126 * </li> 127 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 128 * information about the person whose identifier is "1".</p> 129 * </li> 130 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 131 * a list of people, which the user can browse through. This example is a 132 * typical top-level entry into the Contacts application, showing you the 133 * list of people. Selecting a particular person to view would result in a 134 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 135 * being used to start an activity to display that person.</p> 136 * </li> 137 * </ul> 138 * 139 * <p>In addition to these primary attributes, there are a number of secondary 140 * attributes that you can also include with an intent:</p> 141 * 142 * <ul> 143 * <li> <p><b>category</b> -- Gives additional information about the action 144 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 145 * appear in the Launcher as a top-level application, while 146 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 147 * of alternative actions the user can perform on a piece of data.</p> 148 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 149 * intent data. Normally the type is inferred from the data itself. 150 * By setting this attribute, you disable that evaluation and force 151 * an explicit type.</p> 152 * <li> <p><b>component</b> -- Specifies an explicit name of a component 153 * class to use for the intent. Normally this is determined by looking 154 * at the other information in the intent (the action, data/type, and 155 * categories) and matching that with a component that can handle it. 156 * If this attribute is set then none of the evaluation is performed, 157 * and this component is used exactly as is. By specifying this attribute, 158 * all of the other Intent attributes become optional.</p> 159 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 160 * This can be used to provide extended information to the component. 161 * For example, if we have a action to send an e-mail message, we could 162 * also include extra pieces of data here to supply a subject, body, 163 * etc.</p> 164 * </ul> 165 * 166 * <p>Here are some examples of other operations you can specify as intents 167 * using these additional parameters:</p> 168 * 169 * <ul> 170 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 171 * Launch the home screen.</p> 172 * </li> 173 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 174 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 175 * vnd.android.cursor.item/phone}</i></b> 176 * -- Display the list of people's phone numbers, allowing the user to 177 * browse through them and pick one and return it to the parent activity.</p> 178 * </li> 179 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 180 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 181 * -- Display all pickers for data that can be opened with 182 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 183 * allowing the user to pick one of them and then some data inside of it 184 * and returning the resulting URI to the caller. This can be used, 185 * for example, in an e-mail application to allow the user to pick some 186 * data to include as an attachment.</p> 187 * </li> 188 * </ul> 189 * 190 * <p>There are a variety of standard Intent action and category constants 191 * defined in the Intent class, but applications can also define their own. 192 * These strings use java style scoping, to ensure they are unique -- for 193 * example, the standard {@link #ACTION_VIEW} is called 194 * "android.intent.action.VIEW".</p> 195 * 196 * <p>Put together, the set of actions, data types, categories, and extra data 197 * defines a language for the system allowing for the expression of phrases 198 * such as "call john smith's cell". As applications are added to the system, 199 * they can extend this language by adding new actions, types, and categories, or 200 * they can modify the behavior of existing phrases by supplying their own 201 * activities that handle them.</p> 202 * 203 * <a name="IntentResolution"></a> 204 * <h3>Intent Resolution</h3> 205 * 206 * <p>There are two primary forms of intents you will use. 207 * 208 * <ul> 209 * <li> <p><b>Explicit Intents</b> have specified a component (via 210 * {@link #setComponent} or {@link #setClass}), which provides the exact 211 * class to be run. Often these will not include any other information, 212 * simply being a way for an application to launch various internal 213 * activities it has as the user interacts with the application. 214 * 215 * <li> <p><b>Implicit Intents</b> have not specified a component; 216 * instead, they must include enough information for the system to 217 * determine which of the available components is best to run for that 218 * intent. 219 * </ul> 220 * 221 * <p>When using implicit intents, given such an arbitrary intent we need to 222 * know what to do with it. This is handled by the process of <em>Intent 223 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 224 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 225 * more activities/receivers) that can handle it.</p> 226 * 227 * <p>The intent resolution mechanism basically revolves around matching an 228 * Intent against all of the <intent-filter> descriptions in the 229 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 230 * objects explicitly registered with {@link Context#registerReceiver}.) More 231 * details on this can be found in the documentation on the {@link 232 * IntentFilter} class.</p> 233 * 234 * <p>There are three pieces of information in the Intent that are used for 235 * resolution: the action, type, and category. Using this information, a query 236 * is done on the {@link PackageManager} for a component that can handle the 237 * intent. The appropriate component is determined based on the intent 238 * information supplied in the <code>AndroidManifest.xml</code> file as 239 * follows:</p> 240 * 241 * <ul> 242 * <li> <p>The <b>action</b>, if given, must be listed by the component as 243 * one it handles.</p> 244 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 245 * already supplied in the Intent. Like the action, if a type is 246 * included in the intent (either explicitly or implicitly in its 247 * data), then this must be listed by the component as one it handles.</p> 248 * <li> For data that is not a <code>content:</code> URI and where no explicit 249 * type is included in the Intent, instead the <b>scheme</b> of the 250 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 251 * considered. Again like the action, if we are matching a scheme it 252 * must be listed by the component as one it can handle. 253 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 254 * by the activity as categories it handles. That is, if you include 255 * the categories {@link #CATEGORY_LAUNCHER} and 256 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 257 * with an intent that lists <em>both</em> of those categories. 258 * Activities will very often need to support the 259 * {@link #CATEGORY_DEFAULT} so that they can be found by 260 * {@link Context#startActivity Context.startActivity()}.</p> 261 * </ul> 262 * 263 * <p>For example, consider the Note Pad sample application that 264 * allows user to browse through a list of notes data and view details about 265 * individual items. Text in italics indicate places were you would replace a 266 * name with one specific to your own package.</p> 267 * 268 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 269 * package="<i>com.android.notepad</i>"> 270 * <application android:icon="@drawable/app_notes" 271 * android:label="@string/app_name"> 272 * 273 * <provider class=".NotePadProvider" 274 * android:authorities="<i>com.google.provider.NotePad</i>" /> 275 * 276 * <activity class=".NotesList" android:label="@string/title_notes_list"> 277 * <intent-filter> 278 * <action android:name="android.intent.action.MAIN" /> 279 * <category android:name="android.intent.category.LAUNCHER" /> 280 * </intent-filter> 281 * <intent-filter> 282 * <action android:name="android.intent.action.VIEW" /> 283 * <action android:name="android.intent.action.EDIT" /> 284 * <action android:name="android.intent.action.PICK" /> 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 * <intent-filter> 289 * <action android:name="android.intent.action.GET_CONTENT" /> 290 * <category android:name="android.intent.category.DEFAULT" /> 291 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 292 * </intent-filter> 293 * </activity> 294 * 295 * <activity class=".NoteEditor" android:label="@string/title_note"> 296 * <intent-filter android:label="@string/resolve_edit"> 297 * <action android:name="android.intent.action.VIEW" /> 298 * <action android:name="android.intent.action.EDIT" /> 299 * <category android:name="android.intent.category.DEFAULT" /> 300 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 301 * </intent-filter> 302 * 303 * <intent-filter> 304 * <action android:name="android.intent.action.INSERT" /> 305 * <category android:name="android.intent.category.DEFAULT" /> 306 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 307 * </intent-filter> 308 * 309 * </activity> 310 * 311 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 312 * android:theme="@android:style/Theme.Dialog"> 313 * <intent-filter android:label="@string/resolve_title"> 314 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 315 * <category android:name="android.intent.category.DEFAULT" /> 316 * <category android:name="android.intent.category.ALTERNATIVE" /> 317 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 318 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 319 * </intent-filter> 320 * </activity> 321 * 322 * </application> 323 * </manifest></pre> 324 * 325 * <p>The first activity, 326 * <code>com.android.notepad.NotesList</code>, serves as our main 327 * entry into the app. It can do three things as described by its three intent 328 * templates: 329 * <ol> 330 * <li><pre> 331 * <intent-filter> 332 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 333 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 334 * </intent-filter></pre> 335 * <p>This provides a top-level entry into the NotePad application: the standard 336 * MAIN action is a main entry point (not requiring any other information in 337 * the Intent), and the LAUNCHER category says that this entry point should be 338 * listed in the application launcher.</p> 339 * <li><pre> 340 * <intent-filter> 341 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 342 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 343 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 344 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 345 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 346 * </intent-filter></pre> 347 * <p>This declares the things that the activity can do on a directory of 348 * notes. The type being supported is given with the <type> tag, where 349 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 350 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 351 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 352 * The activity allows the user to view or edit the directory of data (via 353 * the VIEW and EDIT actions), or to pick a particular note and return it 354 * to the caller (via the PICK action). Note also the DEFAULT category 355 * supplied here: this is <em>required</em> for the 356 * {@link Context#startActivity Context.startActivity} method to resolve your 357 * activity when its component name is not explicitly specified.</p> 358 * <li><pre> 359 * <intent-filter> 360 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 361 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 362 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 363 * </intent-filter></pre> 364 * <p>This filter describes the ability return to the caller a note selected by 365 * the user without needing to know where it came from. The data type 366 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 367 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 368 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 369 * The GET_CONTENT action is similar to the PICK action, where the activity 370 * will return to its caller a piece of data selected by the user. Here, 371 * however, the caller specifies the type of data they desire instead of 372 * the type of data the user will be picking from.</p> 373 * </ol> 374 * 375 * <p>Given these capabilities, the following intents will resolve to the 376 * NotesList activity:</p> 377 * 378 * <ul> 379 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 380 * activities that can be used as top-level entry points into an 381 * application.</p> 382 * <li> <p><b>{ action=android.app.action.MAIN, 383 * category=android.app.category.LAUNCHER }</b> is the actual intent 384 * used by the Launcher to populate its top-level list.</p> 385 * <li> <p><b>{ action=android.intent.action.VIEW 386 * data=content://com.google.provider.NotePad/notes }</b> 387 * displays a list of all the notes under 388 * "content://com.google.provider.NotePad/notes", which 389 * the user can browse through and see the details on.</p> 390 * <li> <p><b>{ action=android.app.action.PICK 391 * data=content://com.google.provider.NotePad/notes }</b> 392 * provides a list of the notes under 393 * "content://com.google.provider.NotePad/notes", from which 394 * the user can pick a note whose data URL is returned back to the caller.</p> 395 * <li> <p><b>{ action=android.app.action.GET_CONTENT 396 * type=vnd.android.cursor.item/vnd.google.note }</b> 397 * is similar to the pick action, but allows the caller to specify the 398 * kind of data they want back so that the system can find the appropriate 399 * activity to pick something of that data type.</p> 400 * </ul> 401 * 402 * <p>The second activity, 403 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 404 * note entry and allows them to edit it. It can do two things as described 405 * by its two intent templates: 406 * <ol> 407 * <li><pre> 408 * <intent-filter android:label="@string/resolve_edit"> 409 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 410 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 411 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 412 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 413 * </intent-filter></pre> 414 * <p>The first, primary, purpose of this activity is to let the user interact 415 * with a single note, as decribed by the MIME type 416 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 417 * either VIEW a note or allow the user to EDIT it. Again we support the 418 * DEFAULT category to allow the activity to be launched without explicitly 419 * specifying its component.</p> 420 * <li><pre> 421 * <intent-filter> 422 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 423 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 424 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 425 * </intent-filter></pre> 426 * <p>The secondary use of this activity is to insert a new note entry into 427 * an existing directory of notes. This is used when the user creates a new 428 * note: the INSERT action is executed on the directory of notes, causing 429 * this activity to run and have the user create the new note data which 430 * it then adds to the content provider.</p> 431 * </ol> 432 * 433 * <p>Given these capabilities, the following intents will resolve to the 434 * NoteEditor activity:</p> 435 * 436 * <ul> 437 * <li> <p><b>{ action=android.intent.action.VIEW 438 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 439 * shows the user the content of note <var>{ID}</var>.</p> 440 * <li> <p><b>{ action=android.app.action.EDIT 441 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 442 * allows the user to edit the content of note <var>{ID}</var>.</p> 443 * <li> <p><b>{ action=android.app.action.INSERT 444 * data=content://com.google.provider.NotePad/notes }</b> 445 * creates a new, empty note in the notes list at 446 * "content://com.google.provider.NotePad/notes" 447 * and allows the user to edit it. If they keep their changes, the URI 448 * of the newly created note is returned to the caller.</p> 449 * </ul> 450 * 451 * <p>The last activity, 452 * <code>com.android.notepad.TitleEditor</code>, allows the user to 453 * edit the title of a note. This could be implemented as a class that the 454 * application directly invokes (by explicitly setting its component in 455 * the Intent), but here we show a way you can publish alternative 456 * operations on existing data:</p> 457 * 458 * <pre> 459 * <intent-filter android:label="@string/resolve_title"> 460 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 461 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 462 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 463 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 464 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 465 * </intent-filter></pre> 466 * 467 * <p>In the single intent template here, we 468 * have created our own private action called 469 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 470 * edit the title of a note. It must be invoked on a specific note 471 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 472 * view and edit actions, but here displays and edits the title contained 473 * in the note data. 474 * 475 * <p>In addition to supporting the default category as usual, our title editor 476 * also supports two other standard categories: ALTERNATIVE and 477 * SELECTED_ALTERNATIVE.
