It 71 * can be used with {@link Context#startActivity(Intent) startActivity} to 72 * launch an {@link android.app.Activity}, 73 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 74 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 75 * and {@link android.content.Context#startService} or 76 * {@link android.content.Context#bindService} to communicate with a 77 * background {@link android.app.Service}. 78 * 79 * <p>An Intent provides a facility for performing late runtime binding between the code in 80 * different applications. Its most significant use is in the launching of activities, where it 81 * can be thought of as the glue between activities. It is basically a passive data structure 82 * holding an abstract description of an action to be performed.</p> 83 * 84 * <div class="special reference"> 85 * <h3>Developer Guides</h3> 86 * <p>For information about how to create and resolve intents, read the 87 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 88 * developer guide.</p> 89 * </div> 90 * 91 * <a name="IntentStructure"></a> 92 * <h3>Intent Structure</h3> 93 * <p>The primary pieces of information in an intent are:</p> 94 * 95 * <ul> 96 * <li> <p><b>action</b> -- The general action to be performed, such as 97 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 98 * etc.</p> 99 * </li> 100 * <li> <p><b>data</b> -- The data to operate on, such as a person record 101 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 102 * </li> 103 * </ul> 104 * 105 * 106 * <p>Some examples of action/data pairs are:</p> 107 * 108 * <ul> 109 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 110 * information about the person whose identifier is "1".</p> 111 * </li> 112 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 113 * the phone dialer with the person filled in.</p> 114 * </li> 115 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 116 * the phone dialer with the given number filled in. Note how the 117 * VIEW action does what what is considered the most reasonable thing for 118 * a particular URI.</p> 119 * </li> 120 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 121 * the phone dialer with the given number filled in.</p> 122 * </li> 123 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 124 * information about the person whose identifier is "1".</p> 125 * </li> 126 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 127 * a list of people, which the user can browse through. This example is a 128 * typical top-level entry into the Contacts application, showing you the 129 * list of people. Selecting a particular person to view would result in a 130 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 131 * being used to start an activity to display that person.</p> 132 * </li> 133 * </ul> 134 * 135 * <p>In addition to these primary attributes, there are a number of secondary 136 * attributes that you can also include with an intent:</p> 137 * 138 * <ul> 139 * <li> <p><b>category</b> -- Gives additional information about the action 140 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 141 * appear in the Launcher as a top-level application, while 142 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 143 * of alternative actions the user can perform on a piece of data.</p> 144 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 145 * intent data. Normally the type is inferred from the data itself. 146 * By setting this attribute, you disable that evaluation and force 147 * an explicit type.</p> 148 * <li> <p><b>component</b> -- Specifies an explicit name of a component 149 * class to use for the intent. Normally this is determined by looking 150 * at the other information in the intent (the action, data/type, and 151 * categories) and matching that with a component that can handle it. 152 * If this attribute is set then none of the evaluation is performed, 153 * and this component is used exactly as is. By specifying this attribute, 154 * all of the other Intent attributes become optional.</p> 155 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 156 * This can be used to provide extended information to the component. 157 * For example, if we have a action to send an e-mail message, we could 158 * also include extra pieces of data here to supply a subject, body, 159 * etc.</p> 160 * </ul> 161 * 162 * <p>Here are some examples of other operations you can specify as intents 163 * using these additional parameters:</p> 164 * 165 * <ul> 166 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 167 * Launch the home screen.</p> 168 * </li> 169 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 170 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 171 * vnd.android.cursor.item/phone}</i></b> 172 * -- Display the list of people's phone numbers, allowing the user to 173 * browse through them and pick one and return it to the parent activity.</p> 174 * </li> 175 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 176 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 177 * -- Display all pickers for data that can be opened with 178 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 179 * allowing the user to pick one of them and then some data inside of it 180 * and returning the resulting URI to the caller. This can be used, 181 * for example, in an e-mail application to allow the user to pick some 182 * data to include as an attachment.</p> 183 * </li> 184 * </ul> 185 * 186 * <p>There are a variety of standard Intent action and category constants 187 * defined in the Intent class, but applications can also define their own. 188 * These strings use java style scoping, to ensure they are unique -- for 189 * example, the standard {@link #ACTION_VIEW} is called 190 * "android.intent.action.VIEW".</p> 191 * 192 * <p>Put together, the set of actions, data types, categories, and extra data 193 * defines a language for the system allowing for the expression of phrases 194 * such as "call john smith's cell". As applications are added to the system, 195 * they can extend this language by adding new actions, types, and categories, or 196 * they can modify the behavior of existing phrases by supplying their own 197 * activities that handle them.</p> 198 * 199 * <a name="IntentResolution"></a> 200 * <h3>Intent Resolution</h3> 201 * 202 * <p>There are two primary forms of intents you will use. 203 * 204 * <ul> 205 * <li> <p><b>Explicit Intents</b> have specified a component (via 206 * {@link #setComponent} or {@link #setClass}), which provides the exact 207 * class to be run. Often these will not include any other information, 208 * simply being a way for an application to launch various internal 209 * activities it has as the user interacts with the application. 210 * 211 * <li> <p><b>Implicit Intents</b> have not specified a component; 212 * instead, they must include enough information for the system to 213 * determine which of the available components is best to run for that 214 * intent. 215 * </ul> 216 * 217 * <p>When using implicit intents, given such an arbitrary intent we need to 218 * know what to do with it. This is handled by the process of <em>Intent 219 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 220 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 221 * more activities/receivers) that can handle it.</p> 222 * 223 * <p>The intent resolution mechanism basically revolves around matching an 224 * Intent against all of the <intent-filter> descriptions in the 225 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 226 * objects explicitly registered with {@link Context#registerReceiver}.) More 227 * details on this can be found in the documentation on the {@link 228 * IntentFilter} class.</p> 229 * 230 * <p>There are three pieces of information in the Intent that are used for 231 * resolution: the action, type, and category. Using this information, a query 232 * is done on the {@link PackageManager} for a component that can handle the 233 * intent. The appropriate component is determined based on the intent 234 * information supplied in the <code>AndroidManifest.xml</code> file as 235 * follows:</p> 236 * 237 * <ul> 238 * <li> <p>The <b>action</b>, if given, must be listed by the component as 239 * one it handles.</p> 240 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 241 * already supplied in the Intent. Like the action, if a type is 242 * included in the intent (either explicitly or implicitly in its 243 * data), then this must be listed by the component as one it handles.</p> 244 * <li> For data that is not a <code>content:</code> URI and where no explicit 245 * type is included in the Intent, instead the <b>scheme</b> of the 246 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 247 * considered. Again like the action, if we are matching a scheme it 248 * must be listed by the component as one it can handle. 249 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 250 * by the activity as categories it handles. That is, if you include 251 * the categories {@link #CATEGORY_LAUNCHER} and 252 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 253 * with an intent that lists <em>both</em> of those categories. 254 * Activities will very often need to support the 255 * {@link #CATEGORY_DEFAULT} so that they can be found by 256 * {@link Context#startActivity Context.startActivity()}.</p> 257 * </ul> 258 * 259 * <p>For example, consider the Note Pad sample application that 260 * allows user to browse through a list of notes data and view details about 261 * individual items. Text in italics indicate places were you would replace a 262 * name with one specific to your own package.</p> 263 * 264 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 265 * package="<i>com.android.notepad</i>"> 266 * <application android:icon="@drawable/app_notes" 267 * android:label="@string/app_name"> 268 * 269 * <provider class=".NotePadProvider" 270 * android:authorities="<i>com.google.provider.NotePad</i>" /> 271 * 272 * <activity class=".NotesList" android:label="@string/title_notes_list"> 273 * <intent-filter> 274 * <action android:name="android.intent.action.MAIN" /> 275 * <category android:name="android.intent.category.LAUNCHER" /> 276 * </intent-filter> 277 * <intent-filter> 278 * <action android:name="android.intent.action.VIEW" /> 279 * <action android:name="android.intent.action.EDIT" /> 280 * <action android:name="android.intent.action.PICK" /> 281 * <category android:name="android.intent.category.DEFAULT" /> 282 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 283 * </intent-filter> 284 * <intent-filter> 285 * <action android:name="android.intent.action.GET_CONTENT" /> 286 * <category android:name="android.intent.category.DEFAULT" /> 287 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 288 * </intent-filter> 289 * </activity> 290 * 291 * <activity class=".NoteEditor" android:label="@string/title_note"> 292 * <intent-filter android:label="@string/resolve_edit"> 293 * <action android:name="android.intent.action.VIEW" /> 294 * <action android:name="android.intent.action.EDIT" /> 295 * <category android:name="android.intent.category.DEFAULT" /> 296 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 297 * </intent-filter> 298 * 299 * <intent-filter> 300 * <action android:name="android.intent.action.INSERT" /> 301 * <category android:name="android.intent.category.DEFAULT" /> 302 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 303 * </intent-filter> 304 * 305 * </activity> 306 * 307 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 308 * android:theme="@android:style/Theme.Dialog"> 309 * <intent-filter android:label="@string/resolve_title"> 310 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 311 * <category android:name="android.intent.category.DEFAULT" /> 312 * <category android:name="android.intent.category.ALTERNATIVE" /> 313 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 314 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 315 * </intent-filter> 316 * </activity> 317 * 318 * </application> 319 * </manifest></pre> 320 * 321 * <p>The first activity, 322 * <code>com.android.notepad.NotesList</code>, serves as our main 323 * entry into the app. It can do three things as described by its three intent 324 * templates: 325 * <ol> 326 * <li><pre> 327 * <intent-filter> 328 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 329 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 330 * </intent-filter></pre> 331 * <p>This provides a top-level entry into the NotePad application: the standard 332 * MAIN action is a main entry point (not requiring any other information in 333 * the Intent), and the LAUNCHER category says that this entry point should be 334 * listed in the application launcher.</p> 335 * <li><pre> 336 * <intent-filter> 337 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 338 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 339 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 340 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 341 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 342 * </intent-filter></pre> 343 * <p>This declares the things that the activity can do on a directory of 344 * notes. The type being supported is given with the <type> tag, where 345 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 346 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 347 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 348 * The activity allows the user to view or edit the directory of data (via 349 * the VIEW and EDIT actions), or to pick a particular note and return it 350 * to the caller (via the PICK action). Note also the DEFAULT category 351 * supplied here: this is <em>required</em> for the 352 * {@link Context#startActivity Context.startActivity} method to resolve your 353 * activity when its component name is not explicitly specified.</p> 354 * <li><pre> 355 * <intent-filter> 356 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 357 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 358 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 359 * </intent-filter></pre> 360 * <p>This filter describes the ability return to the caller a note selected by 361 * the user without needing to know where it came from. The data type 362 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 363 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 364 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 365 * The GET_CONTENT action is similar to the PICK action, where the activity 366 * will return to its caller a piece of data selected by the user. Here, 367 * however, the caller specifies the type of data they desire instead of 368 * the type of data the user will be picking from.</p> 369 * </ol> 370 * 371 * <p>Given these capabilities, the following intents will resolve to the 372 * NotesList activity:</p> 373 * 374 * <ul> 375 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 376 * activities that can be used as top-level entry points into an 377 * application.</p> 378 * <li> <p><b>{ action=android.app.action.MAIN, 379 * category=android.app.category.LAUNCHER }</b> is the actual intent 380 * used by the Launcher to populate its top-level list.</p> 381 * <li> <p><b>{ action=android.intent.action.VIEW 382 * data=content://com.google.provider.NotePad/notes }</b> 383 * displays a list of all the notes under 384 * "content://com.google.provider.NotePad/notes", which 385 * the user can browse through and see the details on.</p> 386 * <li> <p><b>{ action=android.app.action.PICK 387 * data=content://com.google.provider.NotePad/notes }</b> 388 * provides a list of the notes under 389 * "content://com.google.provider.NotePad/notes", from which 390 * the user can pick a note whose data URL is returned back to the caller.</p> 391 * <li> <p><b>{ action=android.app.action.GET_CONTENT 392 * type=vnd.android.cursor.item/vnd.google.note }</b> 393 * is similar to the pick action, but allows the caller to specify the 394 * kind of data they want back so that the system can find the appropriate 395 * activity to pick something of that data type.</p> 396 * </ul> 397 * 398 * <p>The second activity, 399 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 400 * note entry and allows them to edit it. It can do two things as described 401 * by its two intent templates: 402 * <ol> 403 * <li><pre> 404 * <intent-filter android:label="@string/resolve_edit"> 405 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 406 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 407 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 408 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 409 * </intent-filter></pre> 410 * <p>The first, primary, purpose of this activity is to let the user interact 411 * with a single note, as decribed by the MIME type 412 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 413 * either VIEW a note or allow the user to EDIT it. Again we support the 414 * DEFAULT category to allow the activity to be launched without explicitly 415 * specifying its component.</p> 416 * <li><pre> 417 * <intent-filter> 418 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 419 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 420 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 421 * </intent-filter></pre> 422 * <p>The secondary use of this activity is to insert a new note entry into 423 * an existing directory of notes. This is used when the user creates a new 424 * note: the INSERT action is executed on the directory of notes, causing 425 * this activity to run and have the user create the new note data which 426 * it then adds to the content provider.</p> 427 * </ol> 428 * 429 * <p>Given these capabilities, the following intents will resolve to the 430 * NoteEditor activity:</p> 431 * 432 * <ul> 433 * <li> <p><b>{ action=android.intent.action.VIEW 434 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 435 * shows the user the content of note <var>{ID}</var>.</p> 436 * <li> <p><b>{ action=android.app.action.EDIT 437 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 438 * allows the user to edit the content of note <var>{ID}</var>.</p> 439 * <li> <p><b>{ action=android.app.action.INSERT 440 * data=content://com.google.provider.NotePad/notes }</b> 441 * creates a new, empty note in the notes list at 442 * "content://com.google.provider.NotePad/notes" 443 * and allows the user to edit it. If they keep their changes, the URI 444 * of the newly created note is returned to the caller.</p> 445 * </ul> 446 * 447 * <p>The last activity, 448 * <code>com.android.notepad.TitleEditor</code>, allows the user to 449 * edit the title of a note. This could be implemented as a class that the 450 * application directly invokes (by explicitly setting its component in 451 * the Intent), but here we show a way you can publish alternative 452 * operations on existing data:</p> 453 * 454 * <pre> 455 * <intent-filter android:label="@string/resolve_title"> 456 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 457 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 458 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 459 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 460 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 461 * </intent-filter></pre> 462 * 463 * <p>In the single intent template here, we 464 * have created our own private action called 465 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 466 * edit the title of a note. It must be invoked on a specific note 467 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 468 * view and edit actions, but here displays and edits the title contained 469 * in the note data. 470 * 471 * <p>In addition to supporting the default category as usual, our title editor 472 * also supports two other standard categories: ALTERNATIVE and 473 * SELECTED_ALTERNATIVE.
