It 69 * can be used with {@link Context#startActivity(Intent) startActivity} to 70 * launch an {@link android.app.Activity}, 71 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 72 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 73 * and {@link android.content.Context#startService} or 74 * {@link android.content.Context#bindService} to communicate with a 75 * background {@link android.app.Service}. 76 * 77 * <p>An Intent provides a facility for performing late runtime binding between the code in 78 * different applications. Its most significant use is in the launching of activities, where it 79 * can be thought of as the glue between activities. It is basically a passive data structure 80 * holding an abstract description of an action to be performed.</p> 81 * 82 * <div class="special reference"> 83 * <h3>Developer Guides</h3> 84 * <p>For information about how to create and resolve intents, read the 85 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 86 * developer guide.</p> 87 * </div> 88 * 89 * <a name="IntentStructure"></a> 90 * <h3>Intent Structure</h3> 91 * <p>The primary pieces of information in an intent are:</p> 92 * 93 * <ul> 94 * <li> <p><b>action</b> -- The general action to be performed, such as 95 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 96 * etc.</p> 97 * </li> 98 * <li> <p><b>data</b> -- The data to operate on, such as a person record 99 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 100 * </li> 101 * </ul> 102 * 103 * 104 * <p>Some examples of action/data pairs are:</p> 105 * 106 * <ul> 107 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 108 * information about the person whose identifier is "1".</p> 109 * </li> 110 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 111 * the phone dialer with the person filled in.</p> 112 * </li> 113 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 114 * the phone dialer with the given number filled in. Note how the 115 * VIEW action does what what is considered the most reasonable thing for 116 * a particular URI.</p> 117 * </li> 118 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 119 * the phone dialer with the given number filled in.</p> 120 * </li> 121 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 122 * information about the person whose identifier is "1".</p> 123 * </li> 124 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 125 * a list of people, which the user can browse through. This example is a 126 * typical top-level entry into the Contacts application, showing you the 127 * list of people. Selecting a particular person to view would result in a 128 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 129 * being used to start an activity to display that person.</p> 130 * </li> 131 * </ul> 132 * 133 * <p>In addition to these primary attributes, there are a number of secondary 134 * attributes that you can also include with an intent:</p> 135 * 136 * <ul> 137 * <li> <p><b>category</b> -- Gives additional information about the action 138 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 139 * appear in the Launcher as a top-level application, while 140 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 141 * of alternative actions the user can perform on a piece of data.</p> 142 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 143 * intent data. Normally the type is inferred from the data itself. 144 * By setting this attribute, you disable that evaluation and force 145 * an explicit type.</p> 146 * <li> <p><b>component</b> -- Specifies an explicit name of a component 147 * class to use for the intent. Normally this is determined by looking 148 * at the other information in the intent (the action, data/type, and 149 * categories) and matching that with a component that can handle it. 150 * If this attribute is set then none of the evaluation is performed, 151 * and this component is used exactly as is. By specifying this attribute, 152 * all of the other Intent attributes become optional.</p> 153 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 154 * This can be used to provide extended information to the component. 155 * For example, if we have a action to send an e-mail message, we could 156 * also include extra pieces of data here to supply a subject, body, 157 * etc.</p> 158 * </ul> 159 * 160 * <p>Here are some examples of other operations you can specify as intents 161 * using these additional parameters:</p> 162 * 163 * <ul> 164 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 165 * Launch the home screen.</p> 166 * </li> 167 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 168 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 169 * vnd.android.cursor.item/phone}</i></b> 170 * -- Display the list of people's phone numbers, allowing the user to 171 * browse through them and pick one and return it to the parent activity.</p> 172 * </li> 173 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 174 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 175 * -- Display all pickers for data that can be opened with 176 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 177 * allowing the user to pick one of them and then some data inside of it 178 * and returning the resulting URI to the caller. This can be used, 179 * for example, in an e-mail application to allow the user to pick some 180 * data to include as an attachment.</p> 181 * </li> 182 * </ul> 183 * 184 * <p>There are a variety of standard Intent action and category constants 185 * defined in the Intent class, but applications can also define their own. 186 * These strings use java style scoping, to ensure they are unique -- for 187 * example, the standard {@link #ACTION_VIEW} is called 188 * "android.intent.action.VIEW".</p> 189 * 190 * <p>Put together, the set of actions, data types, categories, and extra data 191 * defines a language for the system allowing for the expression of phrases 192 * such as "call john smith's cell". As applications are added to the system, 193 * they can extend this language by adding new actions, types, and categories, or 194 * they can modify the behavior of existing phrases by supplying their own 195 * activities that handle them.</p> 196 * 197 * <a name="IntentResolution"></a> 198 * <h3>Intent Resolution</h3> 199 * 200 * <p>There are two primary forms of intents you will use. 201 * 202 * <ul> 203 * <li> <p><b>Explicit Intents</b> have specified a component (via 204 * {@link #setComponent} or {@link #setClass}), which provides the exact 205 * class to be run. Often these will not include any other information, 206 * simply being a way for an application to launch various internal 207 * activities it has as the user interacts with the application. 208 * 209 * <li> <p><b>Implicit Intents</b> have not specified a component; 210 * instead, they must include enough information for the system to 211 * determine which of the available components is best to run for that 212 * intent. 213 * </ul> 214 * 215 * <p>When using implicit intents, given such an arbitrary intent we need to 216 * know what to do with it. This is handled by the process of <em>Intent 217 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 218 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 219 * more activities/receivers) that can handle it.</p> 220 * 221 * <p>The intent resolution mechanism basically revolves around matching an 222 * Intent against all of the <intent-filter> descriptions in the 223 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 224 * objects explicitly registered with {@link Context#registerReceiver}.) More 225 * details on this can be found in the documentation on the {@link 226 * IntentFilter} class.</p> 227 * 228 * <p>There are three pieces of information in the Intent that are used for 229 * resolution: the action, type, and category. Using this information, a query 230 * is done on the {@link PackageManager} for a component that can handle the 231 * intent. The appropriate component is determined based on the intent 232 * information supplied in the <code>AndroidManifest.xml</code> file as 233 * follows:</p> 234 * 235 * <ul> 236 * <li> <p>The <b>action</b>, if given, must be listed by the component as 237 * one it handles.</p> 238 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 239 * already supplied in the Intent. Like the action, if a type is 240 * included in the intent (either explicitly or implicitly in its 241 * data), then this must be listed by the component as one it handles.</p> 242 * <li> For data that is not a <code>content:</code> URI and where no explicit 243 * type is included in the Intent, instead the <b>scheme</b> of the 244 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 245 * considered. Again like the action, if we are matching a scheme it 246 * must be listed by the component as one it can handle. 247 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 248 * by the activity as categories it handles. That is, if you include 249 * the categories {@link #CATEGORY_LAUNCHER} and 250 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 251 * with an intent that lists <em>both</em> of those categories. 252 * Activities will very often need to support the 253 * {@link #CATEGORY_DEFAULT} so that they can be found by 254 * {@link Context#startActivity Context.startActivity()}.</p> 255 * </ul> 256 * 257 * <p>For example, consider the Note Pad sample application that 258 * allows user to browse through a list of notes data and view details about 259 * individual items. Text in italics indicate places were you would replace a 260 * name with one specific to your own package.</p> 261 * 262 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 263 * package="<i>com.android.notepad</i>"> 264 * <application android:icon="@drawable/app_notes" 265 * android:label="@string/app_name"> 266 * 267 * <provider class=".NotePadProvider" 268 * android:authorities="<i>com.google.provider.NotePad</i>" /> 269 * 270 * <activity class=".NotesList" android:label="@string/title_notes_list"> 271 * <intent-filter> 272 * <action android:name="android.intent.action.MAIN" /> 273 * <category android:name="android.intent.category.LAUNCHER" /> 274 * </intent-filter> 275 * <intent-filter> 276 * <action android:name="android.intent.action.VIEW" /> 277 * <action android:name="android.intent.action.EDIT" /> 278 * <action android:name="android.intent.action.PICK" /> 279 * <category android:name="android.intent.category.DEFAULT" /> 280 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 281 * </intent-filter> 282 * <intent-filter> 283 * <action android:name="android.intent.action.GET_CONTENT" /> 284 * <category android:name="android.intent.category.DEFAULT" /> 285 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 286 * </intent-filter> 287 * </activity> 288 * 289 * <activity class=".NoteEditor" android:label="@string/title_note"> 290 * <intent-filter android:label="@string/resolve_edit"> 291 * <action android:name="android.intent.action.VIEW" /> 292 * <action android:name="android.intent.action.EDIT" /> 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 * 297 * <intent-filter> 298 * <action android:name="android.intent.action.INSERT" /> 299 * <category android:name="android.intent.category.DEFAULT" /> 300 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 301 * </intent-filter> 302 * 303 * </activity> 304 * 305 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 306 * android:theme="@android:style/Theme.Dialog"> 307 * <intent-filter android:label="@string/resolve_title"> 308 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 309 * <category android:name="android.intent.category.DEFAULT" /> 310 * <category android:name="android.intent.category.ALTERNATIVE" /> 311 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 312 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 313 * </intent-filter> 314 * </activity> 315 * 316 * </application> 317 * </manifest></pre> 318 * 319 * <p>The first activity, 320 * <code>com.android.notepad.NotesList</code>, serves as our main 321 * entry into the app. It can do three things as described by its three intent 322 * templates: 323 * <ol> 324 * <li><pre> 325 * <intent-filter> 326 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 327 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 328 * </intent-filter></pre> 329 * <p>This provides a top-level entry into the NotePad application: the standard 330 * MAIN action is a main entry point (not requiring any other information in 331 * the Intent), and the LAUNCHER category says that this entry point should be 332 * listed in the application launcher.</p> 333 * <li><pre> 334 * <intent-filter> 335 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 336 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 337 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 338 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 339 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 340 * </intent-filter></pre> 341 * <p>This declares the things that the activity can do on a directory of 342 * notes. The type being supported is given with the <type> tag, where 343 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 344 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 345 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 346 * The activity allows the user to view or edit the directory of data (via 347 * the VIEW and EDIT actions), or to pick a particular note and return it 348 * to the caller (via the PICK action). Note also the DEFAULT category 349 * supplied here: this is <em>required</em> for the 350 * {@link Context#startActivity Context.startActivity} method to resolve your 351 * activity when its component name is not explicitly specified.</p> 352 * <li><pre> 353 * <intent-filter> 354 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 355 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 356 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 357 * </intent-filter></pre> 358 * <p>This filter describes the ability return to the caller a note selected by 359 * the user without needing to know where it came from. The data type 360 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 361 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 362 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 363 * The GET_CONTENT action is similar to the PICK action, where the activity 364 * will return to its caller a piece of data selected by the user. Here, 365 * however, the caller specifies the type of data they desire instead of 366 * the type of data the user will be picking from.</p> 367 * </ol> 368 * 369 * <p>Given these capabilities, the following intents will resolve to the 370 * NotesList activity:</p> 371 * 372 * <ul> 373 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 374 * activities that can be used as top-level entry points into an 375 * application.</p> 376 * <li> <p><b>{ action=android.app.action.MAIN, 377 * category=android.app.category.LAUNCHER }</b> is the actual intent 378 * used by the Launcher to populate its top-level list.</p> 379 * <li> <p><b>{ action=android.intent.action.VIEW 380 * data=content://com.google.provider.NotePad/notes }</b> 381 * displays a list of all the notes under 382 * "content://com.google.provider.NotePad/notes", which 383 * the user can browse through and see the details on.</p> 384 * <li> <p><b>{ action=android.app.action.PICK 385 * data=content://com.google.provider.NotePad/notes }</b> 386 * provides a list of the notes under 387 * "content://com.google.provider.NotePad/notes", from which 388 * the user can pick a note whose data URL is returned back to the caller.</p> 389 * <li> <p><b>{ action=android.app.action.GET_CONTENT 390 * type=vnd.android.cursor.item/vnd.google.note }</b> 391 * is similar to the pick action, but allows the caller to specify the 392 * kind of data they want back so that the system can find the appropriate 393 * activity to pick something of that data type.</p> 394 * </ul> 395 * 396 * <p>The second activity, 397 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 398 * note entry and allows them to edit it. It can do two things as described 399 * by its two intent templates: 400 * <ol> 401 * <li><pre> 402 * <intent-filter android:label="@string/resolve_edit"> 403 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 404 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 405 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 406 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 407 * </intent-filter></pre> 408 * <p>The first, primary, purpose of this activity is to let the user interact 409 * with a single note, as decribed by the MIME type 410 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 411 * either VIEW a note or allow the user to EDIT it. Again we support the 412 * DEFAULT category to allow the activity to be launched without explicitly 413 * specifying its component.</p> 414 * <li><pre> 415 * <intent-filter> 416 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 417 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 418 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 419 * </intent-filter></pre> 420 * <p>The secondary use of this activity is to insert a new note entry into 421 * an existing directory of notes. This is used when the user creates a new 422 * note: the INSERT action is executed on the directory of notes, causing 423 * this activity to run and have the user create the new note data which 424 * it then adds to the content provider.</p> 425 * </ol> 426 * 427 * <p>Given these capabilities, the following intents will resolve to the 428 * NoteEditor activity:</p> 429 * 430 * <ul> 431 * <li> <p><b>{ action=android.intent.action.VIEW 432 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 433 * shows the user the content of note <var>{ID}</var>.</p> 434 * <li> <p><b>{ action=android.app.action.EDIT 435 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 436 * allows the user to edit the content of note <var>{ID}</var>.</p> 437 * <li> <p><b>{ action=android.app.action.INSERT 438 * data=content://com.google.provider.NotePad/notes }</b> 439 * creates a new, empty note in the notes list at 440 * "content://com.google.provider.NotePad/notes" 441 * and allows the user to edit it. If they keep their changes, the URI 442 * of the newly created note is returned to the caller.</p> 443 * </ul> 444 * 445 * <p>The last activity, 446 * <code>com.android.notepad.TitleEditor</code>, allows the user to 447 * edit the title of a note. This could be implemented as a class that the 448 * application directly invokes (by explicitly setting its component in 449 * the Intent), but here we show a way you can publish alternative 450 * operations on existing data:</p> 451 * 452 * <pre> 453 * <intent-filter android:label="@string/resolve_title"> 454 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 455 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 456 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 457 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 458 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 459 * </intent-filter></pre> 460 * 461 * <p>In the single intent template here, we 462 * have created our own private action called 463 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 464 * edit the title of a note. It must be invoked on a specific note 465 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 466 * view and edit actions, but here displays and edits the title contained 467 * in the note data. 468 * 469 * <p>In addition to supporting the default category as usual, our title editor 470 * also supports two other standard categories: ALTERNATIVE and 471 * SELECTED_ALTERNATIVE.
