It 70 * can be used with {@link Context#startActivity(Intent) startActivity} to 71 * launch an {@link android.app.Activity}, 72 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 73 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 74 * and {@link android.content.Context#startService} or 75 * {@link android.content.Context#bindService} to communicate with a 76 * background {@link android.app.Service}. 77 * 78 * <p>An Intent provides a facility for performing late runtime binding between the code in 79 * different applications. Its most significant use is in the launching of activities, where it 80 * can be thought of as the glue between activities. It is basically a passive data structure 81 * holding an abstract description of an action to be performed.</p> 82 * 83 * <div class="special reference"> 84 * <h3>Developer Guides</h3> 85 * <p>For information about how to create and resolve intents, read the 86 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 87 * developer guide.</p> 88 * </div> 89 * 90 * <a name="IntentStructure"></a> 91 * <h3>Intent Structure</h3> 92 * <p>The primary pieces of information in an intent are:</p> 93 * 94 * <ul> 95 * <li> <p><b>action</b> -- The general action to be performed, such as 96 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 97 * etc.</p> 98 * </li> 99 * <li> <p><b>data</b> -- The data to operate on, such as a person record 100 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 101 * </li> 102 * </ul> 103 * 104 * 105 * <p>Some examples of action/data pairs are:</p> 106 * 107 * <ul> 108 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 109 * information about the person whose identifier is "1".</p> 110 * </li> 111 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 112 * the phone dialer with the person filled in.</p> 113 * </li> 114 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 115 * the phone dialer with the given number filled in. Note how the 116 * VIEW action does what what is considered the most reasonable thing for 117 * a particular URI.</p> 118 * </li> 119 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 120 * the phone dialer with the given number filled in.</p> 121 * </li> 122 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 123 * information about the person whose identifier is "1".</p> 124 * </li> 125 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 126 * a list of people, which the user can browse through. This example is a 127 * typical top-level entry into the Contacts application, showing you the 128 * list of people. Selecting a particular person to view would result in a 129 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 130 * being used to start an activity to display that person.</p> 131 * </li> 132 * </ul> 133 * 134 * <p>In addition to these primary attributes, there are a number of secondary 135 * attributes that you can also include with an intent:</p> 136 * 137 * <ul> 138 * <li> <p><b>category</b> -- Gives additional information about the action 139 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 140 * appear in the Launcher as a top-level application, while 141 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 142 * of alternative actions the user can perform on a piece of data.</p> 143 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 144 * intent data. Normally the type is inferred from the data itself. 145 * By setting this attribute, you disable that evaluation and force 146 * an explicit type.</p> 147 * <li> <p><b>component</b> -- Specifies an explicit name of a component 148 * class to use for the intent. Normally this is determined by looking 149 * at the other information in the intent (the action, data/type, and 150 * categories) and matching that with a component that can handle it. 151 * If this attribute is set then none of the evaluation is performed, 152 * and this component is used exactly as is. By specifying this attribute, 153 * all of the other Intent attributes become optional.</p> 154 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 155 * This can be used to provide extended information to the component. 156 * For example, if we have a action to send an e-mail message, we could 157 * also include extra pieces of data here to supply a subject, body, 158 * etc.</p> 159 * </ul> 160 * 161 * <p>Here are some examples of other operations you can specify as intents 162 * using these additional parameters:</p> 163 * 164 * <ul> 165 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 166 * Launch the home screen.</p> 167 * </li> 168 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 169 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 170 * vnd.android.cursor.item/phone}</i></b> 171 * -- Display the list of people's phone numbers, allowing the user to 172 * browse through them and pick one and return it to the parent activity.</p> 173 * </li> 174 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 175 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 176 * -- Display all pickers for data that can be opened with 177 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 178 * allowing the user to pick one of them and then some data inside of it 179 * and returning the resulting URI to the caller. This can be used, 180 * for example, in an e-mail application to allow the user to pick some 181 * data to include as an attachment.</p> 182 * </li> 183 * </ul> 184 * 185 * <p>There are a variety of standard Intent action and category constants 186 * defined in the Intent class, but applications can also define their own. 187 * These strings use java style scoping, to ensure they are unique -- for 188 * example, the standard {@link #ACTION_VIEW} is called 189 * "android.intent.action.VIEW".</p> 190 * 191 * <p>Put together, the set of actions, data types, categories, and extra data 192 * defines a language for the system allowing for the expression of phrases 193 * such as "call john smith's cell". As applications are added to the system, 194 * they can extend this language by adding new actions, types, and categories, or 195 * they can modify the behavior of existing phrases by supplying their own 196 * activities that handle them.</p> 197 * 198 * <a name="IntentResolution"></a> 199 * <h3>Intent Resolution</h3> 200 * 201 * <p>There are two primary forms of intents you will use. 202 * 203 * <ul> 204 * <li> <p><b>Explicit Intents</b> have specified a component (via 205 * {@link #setComponent} or {@link #setClass}), which provides the exact 206 * class to be run. Often these will not include any other information, 207 * simply being a way for an application to launch various internal 208 * activities it has as the user interacts with the application. 209 * 210 * <li> <p><b>Implicit Intents</b> have not specified a component; 211 * instead, they must include enough information for the system to 212 * determine which of the available components is best to run for that 213 * intent. 214 * </ul> 215 * 216 * <p>When using implicit intents, given such an arbitrary intent we need to 217 * know what to do with it. This is handled by the process of <em>Intent 218 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 219 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 220 * more activities/receivers) that can handle it.</p> 221 * 222 * <p>The intent resolution mechanism basically revolves around matching an 223 * Intent against all of the <intent-filter> descriptions in the 224 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 225 * objects explicitly registered with {@link Context#registerReceiver}.) More 226 * details on this can be found in the documentation on the {@link 227 * IntentFilter} class.</p> 228 * 229 * <p>There are three pieces of information in the Intent that are used for 230 * resolution: the action, type, and category. Using this information, a query 231 * is done on the {@link PackageManager} for a component that can handle the 232 * intent. The appropriate component is determined based on the intent 233 * information supplied in the <code>AndroidManifest.xml</code> file as 234 * follows:</p> 235 * 236 * <ul> 237 * <li> <p>The <b>action</b>, if given, must be listed by the component as 238 * one it handles.</p> 239 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 240 * already supplied in the Intent. Like the action, if a type is 241 * included in the intent (either explicitly or implicitly in its 242 * data), then this must be listed by the component as one it handles.</p> 243 * <li> For data that is not a <code>content:</code> URI and where no explicit 244 * type is included in the Intent, instead the <b>scheme</b> of the 245 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 246 * considered. Again like the action, if we are matching a scheme it 247 * must be listed by the component as one it can handle. 248 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 249 * by the activity as categories it handles. That is, if you include 250 * the categories {@link #CATEGORY_LAUNCHER} and 251 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 252 * with an intent that lists <em>both</em> of those categories. 253 * Activities will very often need to support the 254 * {@link #CATEGORY_DEFAULT} so that they can be found by 255 * {@link Context#startActivity Context.startActivity()}.</p> 256 * </ul> 257 * 258 * <p>For example, consider the Note Pad sample application that 259 * allows user to browse through a list of notes data and view details about 260 * individual items. Text in italics indicate places were you would replace a 261 * name with one specific to your own package.</p> 262 * 263 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 264 * package="<i>com.android.notepad</i>"> 265 * <application android:icon="@drawable/app_notes" 266 * android:label="@string/app_name"> 267 * 268 * <provider class=".NotePadProvider" 269 * android:authorities="<i>com.google.provider.NotePad</i>" /> 270 * 271 * <activity class=".NotesList" android:label="@string/title_notes_list"> 272 * <intent-filter> 273 * <action android:name="android.intent.action.MAIN" /> 274 * <category android:name="android.intent.category.LAUNCHER" /> 275 * </intent-filter> 276 * <intent-filter> 277 * <action android:name="android.intent.action.VIEW" /> 278 * <action android:name="android.intent.action.EDIT" /> 279 * <action android:name="android.intent.action.PICK" /> 280 * <category android:name="android.intent.category.DEFAULT" /> 281 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 282 * </intent-filter> 283 * <intent-filter> 284 * <action android:name="android.intent.action.GET_CONTENT" /> 285 * <category android:name="android.intent.category.DEFAULT" /> 286 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 287 * </intent-filter> 288 * </activity> 289 * 290 * <activity class=".NoteEditor" android:label="@string/title_note"> 291 * <intent-filter android:label="@string/resolve_edit"> 292 * <action android:name="android.intent.action.VIEW" /> 293 * <action android:name="android.intent.action.EDIT" /> 294 * <category android:name="android.intent.category.DEFAULT" /> 295 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 296 * </intent-filter> 297 * 298 * <intent-filter> 299 * <action android:name="android.intent.action.INSERT" /> 300 * <category android:name="android.intent.category.DEFAULT" /> 301 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 302 * </intent-filter> 303 * 304 * </activity> 305 * 306 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 307 * android:theme="@android:style/Theme.Dialog"> 308 * <intent-filter android:label="@string/resolve_title"> 309 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 310 * <category android:name="android.intent.category.DEFAULT" /> 311 * <category android:name="android.intent.category.ALTERNATIVE" /> 312 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 313 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 314 * </intent-filter> 315 * </activity> 316 * 317 * </application> 318 * </manifest></pre> 319 * 320 * <p>The first activity, 321 * <code>com.android.notepad.NotesList</code>, serves as our main 322 * entry into the app. It can do three things as described by its three intent 323 * templates: 324 * <ol> 325 * <li><pre> 326 * <intent-filter> 327 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 328 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 329 * </intent-filter></pre> 330 * <p>This provides a top-level entry into the NotePad application: the standard 331 * MAIN action is a main entry point (not requiring any other information in 332 * the Intent), and the LAUNCHER category says that this entry point should be 333 * listed in the application launcher.</p> 334 * <li><pre> 335 * <intent-filter> 336 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 337 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 338 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 339 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 340 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 341 * </intent-filter></pre> 342 * <p>This declares the things that the activity can do on a directory of 343 * notes. The type being supported is given with the <type> tag, where 344 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 345 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 346 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 347 * The activity allows the user to view or edit the directory of data (via 348 * the VIEW and EDIT actions), or to pick a particular note and return it 349 * to the caller (via the PICK action). Note also the DEFAULT category 350 * supplied here: this is <em>required</em> for the 351 * {@link Context#startActivity Context.startActivity} method to resolve your 352 * activity when its component name is not explicitly specified.</p> 353 * <li><pre> 354 * <intent-filter> 355 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 356 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 357 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 358 * </intent-filter></pre> 359 * <p>This filter describes the ability return to the caller a note selected by 360 * the user without needing to know where it came from. The data type 361 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 362 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 363 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 364 * The GET_CONTENT action is similar to the PICK action, where the activity 365 * will return to its caller a piece of data selected by the user. Here, 366 * however, the caller specifies the type of data they desire instead of 367 * the type of data the user will be picking from.</p> 368 * </ol> 369 * 370 * <p>Given these capabilities, the following intents will resolve to the 371 * NotesList activity:</p> 372 * 373 * <ul> 374 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 375 * activities that can be used as top-level entry points into an 376 * application.</p> 377 * <li> <p><b>{ action=android.app.action.MAIN, 378 * category=android.app.category.LAUNCHER }</b> is the actual intent 379 * used by the Launcher to populate its top-level list.</p> 380 * <li> <p><b>{ action=android.intent.action.VIEW 381 * data=content://com.google.provider.NotePad/notes }</b> 382 * displays a list of all the notes under 383 * "content://com.google.provider.NotePad/notes", which 384 * the user can browse through and see the details on.</p> 385 * <li> <p><b>{ action=android.app.action.PICK 386 * data=content://com.google.provider.NotePad/notes }</b> 387 * provides a list of the notes under 388 * "content://com.google.provider.NotePad/notes", from which 389 * the user can pick a note whose data URL is returned back to the caller.</p> 390 * <li> <p><b>{ action=android.app.action.GET_CONTENT 391 * type=vnd.android.cursor.item/vnd.google.note }</b> 392 * is similar to the pick action, but allows the caller to specify the 393 * kind of data they want back so that the system can find the appropriate 394 * activity to pick something of that data type.</p> 395 * </ul> 396 * 397 * <p>The second activity, 398 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 399 * note entry and allows them to edit it. It can do two things as described 400 * by its two intent templates: 401 * <ol> 402 * <li><pre> 403 * <intent-filter android:label="@string/resolve_edit"> 404 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 405 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 406 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 407 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 408 * </intent-filter></pre> 409 * <p>The first, primary, purpose of this activity is to let the user interact 410 * with a single note, as decribed by the MIME type 411 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 412 * either VIEW a note or allow the user to EDIT it. Again we support the 413 * DEFAULT category to allow the activity to be launched without explicitly 414 * specifying its component.</p> 415 * <li><pre> 416 * <intent-filter> 417 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 418 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 419 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 420 * </intent-filter></pre> 421 * <p>The secondary use of this activity is to insert a new note entry into 422 * an existing directory of notes. This is used when the user creates a new 423 * note: the INSERT action is executed on the directory of notes, causing 424 * this activity to run and have the user create the new note data which 425 * it then adds to the content provider.</p> 426 * </ol> 427 * 428 * <p>Given these capabilities, the following intents will resolve to the 429 * NoteEditor activity:</p> 430 * 431 * <ul> 432 * <li> <p><b>{ action=android.intent.action.VIEW 433 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 434 * shows the user the content of note <var>{ID}</var>.</p> 435 * <li> <p><b>{ action=android.app.action.EDIT 436 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 437 * allows the user to edit the content of note <var>{ID}</var>.</p> 438 * <li> <p><b>{ action=android.app.action.INSERT 439 * data=content://com.google.provider.NotePad/notes }</b> 440 * creates a new, empty note in the notes list at 441 * "content://com.google.provider.NotePad/notes" 442 * and allows the user to edit it. If they keep their changes, the URI 443 * of the newly created note is returned to the caller.</p> 444 * </ul> 445 * 446 * <p>The last activity, 447 * <code>com.android.notepad.TitleEditor</code>, allows the user to 448 * edit the title of a note. This could be implemented as a class that the 449 * application directly invokes (by explicitly setting its component in 450 * the Intent), but here we show a way you can publish alternative 451 * operations on existing data:</p> 452 * 453 * <pre> 454 * <intent-filter android:label="@string/resolve_title"> 455 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 456 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 457 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 458 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 459 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 460 * </intent-filter></pre> 461 * 462 * <p>In the single intent template here, we 463 * have created our own private action called 464 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 465 * edit the title of a note. It must be invoked on a specific note 466 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 467 * view and edit actions, but here displays and edits the title contained 468 * in the note data. 469 * 470 * <p>In addition to supporting the default category as usual, our title editor 471 * also supports two other standard categories: ALTERNATIVE and 472 * SELECTED_ALTERNATIVE.
