It 65 * can be used with {@link Context#startActivity(Intent) startActivity} to 66 * launch an {@link android.app.Activity}, 67 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 68 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 69 * and {@link android.content.Context#startService} or 70 * {@link android.content.Context#bindService} to communicate with a 71 * background {@link android.app.Service}. 72 * 73 * <p>An Intent provides a facility for performing late runtime binding between the code in 74 * different applications. Its most significant use is in the launching of activities, where it 75 * can be thought of as the glue between activities. It is basically a passive data structure 76 * holding an abstract description of an action to be performed.</p> 77 * 78 * <div class="special reference"> 79 * <h3>Developer Guides</h3> 80 * <p>For information about how to create and resolve intents, read the 81 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 82 * developer guide.</p> 83 * </div> 84 * 85 * <a name="IntentStructure"></a> 86 * <h3>Intent Structure</h3> 87 * <p>The primary pieces of information in an intent are:</p> 88 * 89 * <ul> 90 * <li> <p><b>action</b> -- The general action to be performed, such as 91 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 92 * etc.</p> 93 * </li> 94 * <li> <p><b>data</b> -- The data to operate on, such as a person record 95 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 96 * </li> 97 * </ul> 98 * 99 * 100 * <p>Some examples of action/data pairs are:</p> 101 * 102 * <ul> 103 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 104 * information about the person whose identifier is "1".</p> 105 * </li> 106 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 107 * the phone dialer with the person filled in.</p> 108 * </li> 109 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 110 * the phone dialer with the given number filled in. Note how the 111 * VIEW action does what what is considered the most reasonable thing for 112 * a particular URI.</p> 113 * </li> 114 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 115 * the phone dialer with the given number filled in.</p> 116 * </li> 117 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 118 * information about the person whose identifier is "1".</p> 119 * </li> 120 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 121 * a list of people, which the user can browse through. This example is a 122 * typical top-level entry into the Contacts application, showing you the 123 * list of people. Selecting a particular person to view would result in a 124 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 125 * being used to start an activity to display that person.</p> 126 * </li> 127 * </ul> 128 * 129 * <p>In addition to these primary attributes, there are a number of secondary 130 * attributes that you can also include with an intent:</p> 131 * 132 * <ul> 133 * <li> <p><b>category</b> -- Gives additional information about the action 134 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 135 * appear in the Launcher as a top-level application, while 136 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 137 * of alternative actions the user can perform on a piece of data.</p> 138 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 139 * intent data. Normally the type is inferred from the data itself. 140 * By setting this attribute, you disable that evaluation and force 141 * an explicit type.</p> 142 * <li> <p><b>component</b> -- Specifies an explicit name of a component 143 * class to use for the intent. Normally this is determined by looking 144 * at the other information in the intent (the action, data/type, and 145 * categories) and matching that with a component that can handle it. 146 * If this attribute is set then none of the evaluation is performed, 147 * and this component is used exactly as is. By specifying this attribute, 148 * all of the other Intent attributes become optional.</p> 149 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 150 * This can be used to provide extended information to the component. 151 * For example, if we have a action to send an e-mail message, we could 152 * also include extra pieces of data here to supply a subject, body, 153 * etc.</p> 154 * </ul> 155 * 156 * <p>Here are some examples of other operations you can specify as intents 157 * using these additional parameters:</p> 158 * 159 * <ul> 160 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 161 * Launch the home screen.</p> 162 * </li> 163 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 164 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 165 * vnd.android.cursor.item/phone}</i></b> 166 * -- Display the list of people's phone numbers, allowing the user to 167 * browse through them and pick one and return it to the parent activity.</p> 168 * </li> 169 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 170 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 171 * -- Display all pickers for data that can be opened with 172 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 173 * allowing the user to pick one of them and then some data inside of it 174 * and returning the resulting URI to the caller. This can be used, 175 * for example, in an e-mail application to allow the user to pick some 176 * data to include as an attachment.</p> 177 * </li> 178 * </ul> 179 * 180 * <p>There are a variety of standard Intent action and category constants 181 * defined in the Intent class, but applications can also define their own. 182 * These strings use java style scoping, to ensure they are unique -- for 183 * example, the standard {@link #ACTION_VIEW} is called 184 * "android.intent.action.VIEW".</p> 185 * 186 * <p>Put together, the set of actions, data types, categories, and extra data 187 * defines a language for the system allowing for the expression of phrases 188 * such as "call john smith's cell". As applications are added to the system, 189 * they can extend this language by adding new actions, types, and categories, or 190 * they can modify the behavior of existing phrases by supplying their own 191 * activities that handle them.</p> 192 * 193 * <a name="IntentResolution"></a> 194 * <h3>Intent Resolution</h3> 195 * 196 * <p>There are two primary forms of intents you will use. 197 * 198 * <ul> 199 * <li> <p><b>Explicit Intents</b> have specified a component (via 200 * {@link #setComponent} or {@link #setClass}), which provides the exact 201 * class to be run. Often these will not include any other information, 202 * simply being a way for an application to launch various internal 203 * activities it has as the user interacts with the application. 204 * 205 * <li> <p><b>Implicit Intents</b> have not specified a component; 206 * instead, they must include enough information for the system to 207 * determine which of the available components is best to run for that 208 * intent. 209 * </ul> 210 * 211 * <p>When using implicit intents, given such an arbitrary intent we need to 212 * know what to do with it. This is handled by the process of <em>Intent 213 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 214 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 215 * more activities/receivers) that can handle it.</p> 216 * 217 * <p>The intent resolution mechanism basically revolves around matching an 218 * Intent against all of the <intent-filter> descriptions in the 219 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 220 * objects explicitly registered with {@link Context#registerReceiver}.) More 221 * details on this can be found in the documentation on the {@link 222 * IntentFilter} class.</p> 223 * 224 * <p>There are three pieces of information in the Intent that are used for 225 * resolution: the action, type, and category. Using this information, a query 226 * is done on the {@link PackageManager} for a component that can handle the 227 * intent. The appropriate component is determined based on the intent 228 * information supplied in the <code>AndroidManifest.xml</code> file as 229 * follows:</p> 230 * 231 * <ul> 232 * <li> <p>The <b>action</b>, if given, must be listed by the component as 233 * one it handles.</p> 234 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 235 * already supplied in the Intent. Like the action, if a type is 236 * included in the intent (either explicitly or implicitly in its 237 * data), then this must be listed by the component as one it handles.</p> 238 * <li> For data that is not a <code>content:</code> URI and where no explicit 239 * type is included in the Intent, instead the <b>scheme</b> of the 240 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 241 * considered. Again like the action, if we are matching a scheme it 242 * must be listed by the component as one it can handle. 243 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 244 * by the activity as categories it handles. That is, if you include 245 * the categories {@link #CATEGORY_LAUNCHER} and 246 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 247 * with an intent that lists <em>both</em> of those categories. 248 * Activities will very often need to support the 249 * {@link #CATEGORY_DEFAULT} so that they can be found by 250 * {@link Context#startActivity Context.startActivity()}.</p> 251 * </ul> 252 * 253 * <p>For example, consider the Note Pad sample application that 254 * allows user to browse through a list of notes data and view details about 255 * individual items. Text in italics indicate places were you would replace a 256 * name with one specific to your own package.</p> 257 * 258 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 259 * package="<i>com.android.notepad</i>"> 260 * <application android:icon="@drawable/app_notes" 261 * android:label="@string/app_name"> 262 * 263 * <provider class=".NotePadProvider" 264 * android:authorities="<i>com.google.provider.NotePad</i>" /> 265 * 266 * <activity class=".NotesList" android:label="@string/title_notes_list"> 267 * <intent-filter> 268 * <action android:name="android.intent.action.MAIN" /> 269 * <category android:name="android.intent.category.LAUNCHER" /> 270 * </intent-filter> 271 * <intent-filter> 272 * <action android:name="android.intent.action.VIEW" /> 273 * <action android:name="android.intent.action.EDIT" /> 274 * <action android:name="android.intent.action.PICK" /> 275 * <category android:name="android.intent.category.DEFAULT" /> 276 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 277 * </intent-filter> 278 * <intent-filter> 279 * <action android:name="android.intent.action.GET_CONTENT" /> 280 * <category android:name="android.intent.category.DEFAULT" /> 281 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 282 * </intent-filter> 283 * </activity> 284 * 285 * <activity class=".NoteEditor" android:label="@string/title_note"> 286 * <intent-filter android:label="@string/resolve_edit"> 287 * <action android:name="android.intent.action.VIEW" /> 288 * <action android:name="android.intent.action.EDIT" /> 289 * <category android:name="android.intent.category.DEFAULT" /> 290 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 291 * </intent-filter> 292 * 293 * <intent-filter> 294 * <action android:name="android.intent.action.INSERT" /> 295 * <category android:name="android.intent.category.DEFAULT" /> 296 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 297 * </intent-filter> 298 * 299 * </activity> 300 * 301 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 302 * android:theme="@android:style/Theme.Dialog"> 303 * <intent-filter android:label="@string/resolve_title"> 304 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 305 * <category android:name="android.intent.category.DEFAULT" /> 306 * <category android:name="android.intent.category.ALTERNATIVE" /> 307 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 308 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 309 * </intent-filter> 310 * </activity> 311 * 312 * </application> 313 * </manifest></pre> 314 * 315 * <p>The first activity, 316 * <code>com.android.notepad.NotesList</code>, serves as our main 317 * entry into the app. It can do three things as described by its three intent 318 * templates: 319 * <ol> 320 * <li><pre> 321 * <intent-filter> 322 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 323 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 324 * </intent-filter></pre> 325 * <p>This provides a top-level entry into the NotePad application: the standard 326 * MAIN action is a main entry point (not requiring any other information in 327 * the Intent), and the LAUNCHER category says that this entry point should be 328 * listed in the application launcher.</p> 329 * <li><pre> 330 * <intent-filter> 331 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 332 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 333 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 334 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 335 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 336 * </intent-filter></pre> 337 * <p>This declares the things that the activity can do on a directory of 338 * notes. The type being supported is given with the <type> tag, where 339 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 340 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 341 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 342 * The activity allows the user to view or edit the directory of data (via 343 * the VIEW and EDIT actions), or to pick a particular note and return it 344 * to the caller (via the PICK action). Note also the DEFAULT category 345 * supplied here: this is <em>required</em> for the 346 * {@link Context#startActivity Context.startActivity} method to resolve your 347 * activity when its component name is not explicitly specified.</p> 348 * <li><pre> 349 * <intent-filter> 350 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 351 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 352 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 353 * </intent-filter></pre> 354 * <p>This filter describes the ability return to the caller a note selected by 355 * the user without needing to know where it came from. The data type 356 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 357 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 358 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 359 * The GET_CONTENT action is similar to the PICK action, where the activity 360 * will return to its caller a piece of data selected by the user. Here, 361 * however, the caller specifies the type of data they desire instead of 362 * the type of data the user will be picking from.</p> 363 * </ol> 364 * 365 * <p>Given these capabilities, the following intents will resolve to the 366 * NotesList activity:</p> 367 * 368 * <ul> 369 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 370 * activities that can be used as top-level entry points into an 371 * application.</p> 372 * <li> <p><b>{ action=android.app.action.MAIN, 373 * category=android.app.category.LAUNCHER }</b> is the actual intent 374 * used by the Launcher to populate its top-level list.</p> 375 * <li> <p><b>{ action=android.intent.action.VIEW 376 * data=content://com.google.provider.NotePad/notes }</b> 377 * displays a list of all the notes under 378 * "content://com.google.provider.NotePad/notes", which 379 * the user can browse through and see the details on.</p> 380 * <li> <p><b>{ action=android.app.action.PICK 381 * data=content://com.google.provider.NotePad/notes }</b> 382 * provides a list of the notes under 383 * "content://com.google.provider.NotePad/notes", from which 384 * the user can pick a note whose data URL is returned back to the caller.</p> 385 * <li> <p><b>{ action=android.app.action.GET_CONTENT 386 * type=vnd.android.cursor.item/vnd.google.note }</b> 387 * is similar to the pick action, but allows the caller to specify the 388 * kind of data they want back so that the system can find the appropriate 389 * activity to pick something of that data type.</p> 390 * </ul> 391 * 392 * <p>The second activity, 393 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 394 * note entry and allows them to edit it. It can do two things as described 395 * by its two intent templates: 396 * <ol> 397 * <li><pre> 398 * <intent-filter android:label="@string/resolve_edit"> 399 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 400 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 401 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 402 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 403 * </intent-filter></pre> 404 * <p>The first, primary, purpose of this activity is to let the user interact 405 * with a single note, as decribed by the MIME type 406 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 407 * either VIEW a note or allow the user to EDIT it. Again we support the 408 * DEFAULT category to allow the activity to be launched without explicitly 409 * specifying its component.</p> 410 * <li><pre> 411 * <intent-filter> 412 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 413 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 414 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 415 * </intent-filter></pre> 416 * <p>The secondary use of this activity is to insert a new note entry into 417 * an existing directory of notes. This is used when the user creates a new 418 * note: the INSERT action is executed on the directory of notes, causing 419 * this activity to run and have the user create the new note data which 420 * it then adds to the content provider.</p> 421 * </ol> 422 * 423 * <p>Given these capabilities, the following intents will resolve to the 424 * NoteEditor activity:</p> 425 * 426 * <ul> 427 * <li> <p><b>{ action=android.intent.action.VIEW 428 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 429 * shows the user the content of note <var>{ID}</var>.</p> 430 * <li> <p><b>{ action=android.app.action.EDIT 431 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 432 * allows the user to edit the content of note <var>{ID}</var>.</p> 433 * <li> <p><b>{ action=android.app.action.INSERT 434 * data=content://com.google.provider.NotePad/notes }</b> 435 * creates a new, empty note in the notes list at 436 * "content://com.google.provider.NotePad/notes" 437 * and allows the user to edit it. If they keep their changes, the URI 438 * of the newly created note is returned to the caller.</p> 439 * </ul> 440 * 441 * <p>The last activity, 442 * <code>com.android.notepad.TitleEditor</code>, allows the user to 443 * edit the title of a note. This could be implemented as a class that the 444 * application directly invokes (by explicitly setting its component in 445 * the Intent), but here we show a way you can publish alternative 446 * operations on existing data:</p> 447 * 448 * <pre> 449 * <intent-filter android:label="@string/resolve_title"> 450 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 451 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 452 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 453 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 454 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 455 * </intent-filter></pre> 456 * 457 * <p>In the single intent template here, we 458 * have created our own private action called 459 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 460 * edit the title of a note. It must be invoked on a specific note 461 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 462 * view and edit actions, but here displays and edits the title contained 463 * in the note data. 464 * 465 * <p>In addition to supporting the default category as usual, our title editor 466 * also supports two other standard categories: ALTERNATIVE and 467 * SELECTED_ALTERNATIVE.
