It 72 * can be used with {@link Context#startActivity(Intent) startActivity} to 73 * launch an {@link android.app.Activity}, 74 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 75 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 76 * and {@link android.content.Context#startService} or 77 * {@link android.content.Context#bindService} to communicate with a 78 * background {@link android.app.Service}. 79 * 80 * <p>An Intent provides a facility for performing late runtime binding between the code in 81 * different applications. Its most significant use is in the launching of activities, where it 82 * can be thought of as the glue between activities. It is basically a passive data structure 83 * holding an abstract description of an action to be performed.</p> 84 * 85 * <div class="special reference"> 86 * <h3>Developer Guides</h3> 87 * <p>For information about how to create and resolve intents, read the 88 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 89 * developer guide.</p> 90 * </div> 91 * 92 * <a name="IntentStructure"></a> 93 * <h3>Intent Structure</h3> 94 * <p>The primary pieces of information in an intent are:</p> 95 * 96 * <ul> 97 * <li> <p><b>action</b> -- The general action to be performed, such as 98 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 99 * etc.</p> 100 * </li> 101 * <li> <p><b>data</b> -- The data to operate on, such as a person record 102 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 103 * </li> 104 * </ul> 105 * 106 * 107 * <p>Some examples of action/data pairs are:</p> 108 * 109 * <ul> 110 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 111 * information about the person whose identifier is "1".</p> 112 * </li> 113 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 114 * the phone dialer with the person filled in.</p> 115 * </li> 116 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 117 * the phone dialer with the given number filled in. Note how the 118 * VIEW action does what what is considered the most reasonable thing for 119 * a particular URI.</p> 120 * </li> 121 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 122 * the phone dialer with the given number filled in.</p> 123 * </li> 124 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 125 * information about the person whose identifier is "1".</p> 126 * </li> 127 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 128 * a list of people, which the user can browse through. This example is a 129 * typical top-level entry into the Contacts application, showing you the 130 * list of people. Selecting a particular person to view would result in a 131 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 132 * being used to start an activity to display that person.</p> 133 * </li> 134 * </ul> 135 * 136 * <p>In addition to these primary attributes, there are a number of secondary 137 * attributes that you can also include with an intent:</p> 138 * 139 * <ul> 140 * <li> <p><b>category</b> -- Gives additional information about the action 141 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 142 * appear in the Launcher as a top-level application, while 143 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 144 * of alternative actions the user can perform on a piece of data.</p> 145 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 146 * intent data. Normally the type is inferred from the data itself. 147 * By setting this attribute, you disable that evaluation and force 148 * an explicit type.</p> 149 * <li> <p><b>component</b> -- Specifies an explicit name of a component 150 * class to use for the intent. Normally this is determined by looking 151 * at the other information in the intent (the action, data/type, and 152 * categories) and matching that with a component that can handle it. 153 * If this attribute is set then none of the evaluation is performed, 154 * and this component is used exactly as is. By specifying this attribute, 155 * all of the other Intent attributes become optional.</p> 156 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 157 * This can be used to provide extended information to the component. 158 * For example, if we have a action to send an e-mail message, we could 159 * also include extra pieces of data here to supply a subject, body, 160 * etc.</p> 161 * </ul> 162 * 163 * <p>Here are some examples of other operations you can specify as intents 164 * using these additional parameters:</p> 165 * 166 * <ul> 167 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 168 * Launch the home screen.</p> 169 * </li> 170 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 171 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 172 * vnd.android.cursor.item/phone}</i></b> 173 * -- Display the list of people's phone numbers, allowing the user to 174 * browse through them and pick one and return it to the parent activity.</p> 175 * </li> 176 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 177 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 178 * -- Display all pickers for data that can be opened with 179 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 180 * allowing the user to pick one of them and then some data inside of it 181 * and returning the resulting URI to the caller. This can be used, 182 * for example, in an e-mail application to allow the user to pick some 183 * data to include as an attachment.</p> 184 * </li> 185 * </ul> 186 * 187 * <p>There are a variety of standard Intent action and category constants 188 * defined in the Intent class, but applications can also define their own. 189 * These strings use java style scoping, to ensure they are unique -- for 190 * example, the standard {@link #ACTION_VIEW} is called 191 * "android.intent.action.VIEW".</p> 192 * 193 * <p>Put together, the set of actions, data types, categories, and extra data 194 * defines a language for the system allowing for the expression of phrases 195 * such as "call john smith's cell". As applications are added to the system, 196 * they can extend this language by adding new actions, types, and categories, or 197 * they can modify the behavior of existing phrases by supplying their own 198 * activities that handle them.</p> 199 * 200 * <a name="IntentResolution"></a> 201 * <h3>Intent Resolution</h3> 202 * 203 * <p>There are two primary forms of intents you will use. 204 * 205 * <ul> 206 * <li> <p><b>Explicit Intents</b> have specified a component (via 207 * {@link #setComponent} or {@link #setClass}), which provides the exact 208 * class to be run. Often these will not include any other information, 209 * simply being a way for an application to launch various internal 210 * activities it has as the user interacts with the application. 211 * 212 * <li> <p><b>Implicit Intents</b> have not specified a component; 213 * instead, they must include enough information for the system to 214 * determine which of the available components is best to run for that 215 * intent. 216 * </ul> 217 * 218 * <p>When using implicit intents, given such an arbitrary intent we need to 219 * know what to do with it. This is handled by the process of <em>Intent 220 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 221 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 222 * more activities/receivers) that can handle it.</p> 223 * 224 * <p>The intent resolution mechanism basically revolves around matching an 225 * Intent against all of the <intent-filter> descriptions in the 226 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 227 * objects explicitly registered with {@link Context#registerReceiver}.) More 228 * details on this can be found in the documentation on the {@link 229 * IntentFilter} class.</p> 230 * 231 * <p>There are three pieces of information in the Intent that are used for 232 * resolution: the action, type, and category. Using this information, a query 233 * is done on the {@link PackageManager} for a component that can handle the 234 * intent. The appropriate component is determined based on the intent 235 * information supplied in the <code>AndroidManifest.xml</code> file as 236 * follows:</p> 237 * 238 * <ul> 239 * <li> <p>The <b>action</b>, if given, must be listed by the component as 240 * one it handles.</p> 241 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 242 * already supplied in the Intent. Like the action, if a type is 243 * included in the intent (either explicitly or implicitly in its 244 * data), then this must be listed by the component as one it handles.</p> 245 * <li> For data that is not a <code>content:</code> URI and where no explicit 246 * type is included in the Intent, instead the <b>scheme</b> of the 247 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 248 * considered. Again like the action, if we are matching a scheme it 249 * must be listed by the component as one it can handle. 250 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 251 * by the activity as categories it handles. That is, if you include 252 * the categories {@link #CATEGORY_LAUNCHER} and 253 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 254 * with an intent that lists <em>both</em> of those categories. 255 * Activities will very often need to support the 256 * {@link #CATEGORY_DEFAULT} so that they can be found by 257 * {@link Context#startActivity Context.startActivity()}.</p> 258 * </ul> 259 * 260 * <p>For example, consider the Note Pad sample application that 261 * allows user to browse through a list of notes data and view details about 262 * individual items. Text in italics indicate places were you would replace a 263 * name with one specific to your own package.</p> 264 * 265 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 266 * package="<i>com.android.notepad</i>"> 267 * <application android:icon="@drawable/app_notes" 268 * android:label="@string/app_name"> 269 * 270 * <provider class=".NotePadProvider" 271 * android:authorities="<i>com.google.provider.NotePad</i>" /> 272 * 273 * <activity class=".NotesList" android:label="@string/title_notes_list"> 274 * <intent-filter> 275 * <action android:name="android.intent.action.MAIN" /> 276 * <category android:name="android.intent.category.LAUNCHER" /> 277 * </intent-filter> 278 * <intent-filter> 279 * <action android:name="android.intent.action.VIEW" /> 280 * <action android:name="android.intent.action.EDIT" /> 281 * <action android:name="android.intent.action.PICK" /> 282 * <category android:name="android.intent.category.DEFAULT" /> 283 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 284 * </intent-filter> 285 * <intent-filter> 286 * <action android:name="android.intent.action.GET_CONTENT" /> 287 * <category android:name="android.intent.category.DEFAULT" /> 288 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 289 * </intent-filter> 290 * </activity> 291 * 292 * <activity class=".NoteEditor" android:label="@string/title_note"> 293 * <intent-filter android:label="@string/resolve_edit"> 294 * <action android:name="android.intent.action.VIEW" /> 295 * <action android:name="android.intent.action.EDIT" /> 296 * <category android:name="android.intent.category.DEFAULT" /> 297 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 298 * </intent-filter> 299 * 300 * <intent-filter> 301 * <action android:name="android.intent.action.INSERT" /> 302 * <category android:name="android.intent.category.DEFAULT" /> 303 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 304 * </intent-filter> 305 * 306 * </activity> 307 * 308 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 309 * android:theme="@android:style/Theme.Dialog"> 310 * <intent-filter android:label="@string/resolve_title"> 311 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 312 * <category android:name="android.intent.category.DEFAULT" /> 313 * <category android:name="android.intent.category.ALTERNATIVE" /> 314 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 315 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 316 * </intent-filter> 317 * </activity> 318 * 319 * </application> 320 * </manifest></pre> 321 * 322 * <p>The first activity, 323 * <code>com.android.notepad.NotesList</code>, serves as our main 324 * entry into the app. It can do three things as described by its three intent 325 * templates: 326 * <ol> 327 * <li><pre> 328 * <intent-filter> 329 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 330 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 331 * </intent-filter></pre> 332 * <p>This provides a top-level entry into the NotePad application: the standard 333 * MAIN action is a main entry point (not requiring any other information in 334 * the Intent), and the LAUNCHER category says that this entry point should be 335 * listed in the application launcher.</p> 336 * <li><pre> 337 * <intent-filter> 338 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 339 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 340 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 341 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 342 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 343 * </intent-filter></pre> 344 * <p>This declares the things that the activity can do on a directory of 345 * notes. The type being supported is given with the <type> tag, where 346 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 347 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 348 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 349 * The activity allows the user to view or edit the directory of data (via 350 * the VIEW and EDIT actions), or to pick a particular note and return it 351 * to the caller (via the PICK action). Note also the DEFAULT category 352 * supplied here: this is <em>required</em> for the 353 * {@link Context#startActivity Context.startActivity} method to resolve your 354 * activity when its component name is not explicitly specified.</p> 355 * <li><pre> 356 * <intent-filter> 357 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 358 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 359 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 360 * </intent-filter></pre> 361 * <p>This filter describes the ability return to the caller a note selected by 362 * the user without needing to know where it came from. The data type 363 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 364 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 365 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 366 * The GET_CONTENT action is similar to the PICK action, where the activity 367 * will return to its caller a piece of data selected by the user. Here, 368 * however, the caller specifies the type of data they desire instead of 369 * the type of data the user will be picking from.</p> 370 * </ol> 371 * 372 * <p>Given these capabilities, the following intents will resolve to the 373 * NotesList activity:</p> 374 * 375 * <ul> 376 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 377 * activities that can be used as top-level entry points into an 378 * application.</p> 379 * <li> <p><b>{ action=android.app.action.MAIN, 380 * category=android.app.category.LAUNCHER }</b> is the actual intent 381 * used by the Launcher to populate its top-level list.</p> 382 * <li> <p><b>{ action=android.intent.action.VIEW 383 * data=content://com.google.provider.NotePad/notes }</b> 384 * displays a list of all the notes under 385 * "content://com.google.provider.NotePad/notes", which 386 * the user can browse through and see the details on.</p> 387 * <li> <p><b>{ action=android.app.action.PICK 388 * data=content://com.google.provider.NotePad/notes }</b> 389 * provides a list of the notes under 390 * "content://com.google.provider.NotePad/notes", from which 391 * the user can pick a note whose data URL is returned back to the caller.</p> 392 * <li> <p><b>{ action=android.app.action.GET_CONTENT 393 * type=vnd.android.cursor.item/vnd.google.note }</b> 394 * is similar to the pick action, but allows the caller to specify the 395 * kind of data they want back so that the system can find the appropriate 396 * activity to pick something of that data type.</p> 397 * </ul> 398 * 399 * <p>The second activity, 400 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 401 * note entry and allows them to edit it. It can do two things as described 402 * by its two intent templates: 403 * <ol> 404 * <li><pre> 405 * <intent-filter android:label="@string/resolve_edit"> 406 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 407 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 408 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 409 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 410 * </intent-filter></pre> 411 * <p>The first, primary, purpose of this activity is to let the user interact 412 * with a single note, as decribed by the MIME type 413 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 414 * either VIEW a note or allow the user to EDIT it. Again we support the 415 * DEFAULT category to allow the activity to be launched without explicitly 416 * specifying its component.</p> 417 * <li><pre> 418 * <intent-filter> 419 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 420 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 421 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 422 * </intent-filter></pre> 423 * <p>The secondary use of this activity is to insert a new note entry into 424 * an existing directory of notes. This is used when the user creates a new 425 * note: the INSERT action is executed on the directory of notes, causing 426 * this activity to run and have the user create the new note data which 427 * it then adds to the content provider.</p> 428 * </ol> 429 * 430 * <p>Given these capabilities, the following intents will resolve to the 431 * NoteEditor activity:</p> 432 * 433 * <ul> 434 * <li> <p><b>{ action=android.intent.action.VIEW 435 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 436 * shows the user the content of note <var>{ID}</var>.</p> 437 * <li> <p><b>{ action=android.app.action.EDIT 438 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 439 * allows the user to edit the content of note <var>{ID}</var>.</p> 440 * <li> <p><b>{ action=android.app.action.INSERT 441 * data=content://com.google.provider.NotePad/notes }</b> 442 * creates a new, empty note in the notes list at 443 * "content://com.google.provider.NotePad/notes" 444 * and allows the user to edit it. If they keep their changes, the URI 445 * of the newly created note is returned to the caller.</p> 446 * </ul> 447 * 448 * <p>The last activity, 449 * <code>com.android.notepad.TitleEditor</code>, allows the user to 450 * edit the title of a note. This could be implemented as a class that the 451 * application directly invokes (by explicitly setting its component in 452 * the Intent), but here we show a way you can publish alternative 453 * operations on existing data:</p> 454 * 455 * <pre> 456 * <intent-filter android:label="@string/resolve_title"> 457 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 458 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 459 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 460 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 461 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 462 * </intent-filter></pre> 463 * 464 * <p>In the single intent template here, we 465 * have created our own private action called 466 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 467 * edit the title of a note. It must be invoked on a specific note 468 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 469 * view and edit actions, but here displays and edits the title contained 470 * in the note data. 471 * 472 * <p>In addition to supporting the default category as usual, our title editor 473 * also supports two other standard categories: ALTERNATIVE and 474 * SELECTED_ALTERNATIVE.
