It 63 * can be used with {@link Context#startActivity(Intent) startActivity} to 64 * launch an {@link android.app.Activity}, 65 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 66 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 67 * and {@link android.content.Context#startService} or 68 * {@link android.content.Context#bindService} to communicate with a 69 * background {@link android.app.Service}. 70 * 71 * <p>An Intent provides a facility for performing late runtime binding between the code in 72 * different applications. Its most significant use is in the launching of activities, where it 73 * can be thought of as the glue between activities. It is basically a passive data structure 74 * holding an abstract description of an action to be performed.</p> 75 * 76 * <div class="special reference"> 77 * <h3>Developer Guides</h3> 78 * <p>For information about how to create and resolve intents, read the 79 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 80 * developer guide.</p> 81 * </div> 82 * 83 * <a name="IntentStructure"></a> 84 * <h3>Intent Structure</h3> 85 * <p>The primary pieces of information in an intent are:</p> 86 * 87 * <ul> 88 * <li> <p><b>action</b> -- The general action to be performed, such as 89 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 90 * etc.</p> 91 * </li> 92 * <li> <p><b>data</b> -- The data to operate on, such as a person record 93 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 94 * </li> 95 * </ul> 96 * 97 * 98 * <p>Some examples of action/data pairs are:</p> 99 * 100 * <ul> 101 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 102 * information about the person whose identifier is "1".</p> 103 * </li> 104 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 105 * the phone dialer with the person filled in.</p> 106 * </li> 107 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 108 * the phone dialer with the given number filled in. Note how the 109 * VIEW action does what what is considered the most reasonable thing for 110 * a particular URI.</p> 111 * </li> 112 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 113 * the phone dialer with the given number filled in.</p> 114 * </li> 115 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 116 * information about the person whose identifier is "1".</p> 117 * </li> 118 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 119 * a list of people, which the user can browse through. This example is a 120 * typical top-level entry into the Contacts application, showing you the 121 * list of people. Selecting a particular person to view would result in a 122 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 123 * being used to start an activity to display that person.</p> 124 * </li> 125 * </ul> 126 * 127 * <p>In addition to these primary attributes, there are a number of secondary 128 * attributes that you can also include with an intent:</p> 129 * 130 * <ul> 131 * <li> <p><b>category</b> -- Gives additional information about the action 132 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 133 * appear in the Launcher as a top-level application, while 134 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 135 * of alternative actions the user can perform on a piece of data.</p> 136 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 137 * intent data. Normally the type is inferred from the data itself. 138 * By setting this attribute, you disable that evaluation and force 139 * an explicit type.</p> 140 * <li> <p><b>component</b> -- Specifies an explicit name of a component 141 * class to use for the intent. Normally this is determined by looking 142 * at the other information in the intent (the action, data/type, and 143 * categories) and matching that with a component that can handle it. 144 * If this attribute is set then none of the evaluation is performed, 145 * and this component is used exactly as is. By specifying this attribute, 146 * all of the other Intent attributes become optional.</p> 147 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 148 * This can be used to provide extended information to the component. 149 * For example, if we have a action to send an e-mail message, we could 150 * also include extra pieces of data here to supply a subject, body, 151 * etc.</p> 152 * </ul> 153 * 154 * <p>Here are some examples of other operations you can specify as intents 155 * using these additional parameters:</p> 156 * 157 * <ul> 158 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 159 * Launch the home screen.</p> 160 * </li> 161 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 162 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 163 * vnd.android.cursor.item/phone}</i></b> 164 * -- Display the list of people's phone numbers, allowing the user to 165 * browse through them and pick one and return it to the parent activity.</p> 166 * </li> 167 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 168 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 169 * -- Display all pickers for data that can be opened with 170 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 171 * allowing the user to pick one of them and then some data inside of it 172 * and returning the resulting URI to the caller. This can be used, 173 * for example, in an e-mail application to allow the user to pick some 174 * data to include as an attachment.</p> 175 * </li> 176 * </ul> 177 * 178 * <p>There are a variety of standard Intent action and category constants 179 * defined in the Intent class, but applications can also define their own. 180 * These strings use java style scoping, to ensure they are unique -- for 181 * example, the standard {@link #ACTION_VIEW} is called 182 * "android.intent.action.VIEW".</p> 183 * 184 * <p>Put together, the set of actions, data types, categories, and extra data 185 * defines a language for the system allowing for the expression of phrases 186 * such as "call john smith's cell". As applications are added to the system, 187 * they can extend this language by adding new actions, types, and categories, or 188 * they can modify the behavior of existing phrases by supplying their own 189 * activities that handle them.</p> 190 * 191 * <a name="IntentResolution"></a> 192 * <h3>Intent Resolution</h3> 193 * 194 * <p>There are two primary forms of intents you will use. 195 * 196 * <ul> 197 * <li> <p><b>Explicit Intents</b> have specified a component (via 198 * {@link #setComponent} or {@link #setClass}), which provides the exact 199 * class to be run. Often these will not include any other information, 200 * simply being a way for an application to launch various internal 201 * activities it has as the user interacts with the application. 202 * 203 * <li> <p><b>Implicit Intents</b> have not specified a component; 204 * instead, they must include enough information for the system to 205 * determine which of the available components is best to run for that 206 * intent. 207 * </ul> 208 * 209 * <p>When using implicit intents, given such an arbitrary intent we need to 210 * know what to do with it. This is handled by the process of <em>Intent 211 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 212 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 213 * more activities/receivers) that can handle it.</p> 214 * 215 * <p>The intent resolution mechanism basically revolves around matching an 216 * Intent against all of the <intent-filter> descriptions in the 217 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 218 * objects explicitly registered with {@link Context#registerReceiver}.) More 219 * details on this can be found in the documentation on the {@link 220 * IntentFilter} class.</p> 221 * 222 * <p>There are three pieces of information in the Intent that are used for 223 * resolution: the action, type, and category. Using this information, a query 224 * is done on the {@link PackageManager} for a component that can handle the 225 * intent. The appropriate component is determined based on the intent 226 * information supplied in the <code>AndroidManifest.xml</code> file as 227 * follows:</p> 228 * 229 * <ul> 230 * <li> <p>The <b>action</b>, if given, must be listed by the component as 231 * one it handles.</p> 232 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 233 * already supplied in the Intent. Like the action, if a type is 234 * included in the intent (either explicitly or implicitly in its 235 * data), then this must be listed by the component as one it handles.</p> 236 * <li> For data that is not a <code>content:</code> URI and where no explicit 237 * type is included in the Intent, instead the <b>scheme</b> of the 238 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 239 * considered. Again like the action, if we are matching a scheme it 240 * must be listed by the component as one it can handle. 241 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 242 * by the activity as categories it handles. That is, if you include 243 * the categories {@link #CATEGORY_LAUNCHER} and 244 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 245 * with an intent that lists <em>both</em> of those categories. 246 * Activities will very often need to support the 247 * {@link #CATEGORY_DEFAULT} so that they can be found by 248 * {@link Context#startActivity Context.startActivity()}.</p> 249 * </ul> 250 * 251 * <p>For example, consider the Note Pad sample application that 252 * allows user to browse through a list of notes data and view details about 253 * individual items. Text in italics indicate places were you would replace a 254 * name with one specific to your own package.</p> 255 * 256 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 257 * package="<i>com.android.notepad</i>"> 258 * <application android:icon="@drawable/app_notes" 259 * android:label="@string/app_name"> 260 * 261 * <provider class=".NotePadProvider" 262 * android:authorities="<i>com.google.provider.NotePad</i>" /> 263 * 264 * <activity class=".NotesList" android:label="@string/title_notes_list"> 265 * <intent-filter> 266 * <action android:name="android.intent.action.MAIN" /> 267 * <category android:name="android.intent.category.LAUNCHER" /> 268 * </intent-filter> 269 * <intent-filter> 270 * <action android:name="android.intent.action.VIEW" /> 271 * <action android:name="android.intent.action.EDIT" /> 272 * <action android:name="android.intent.action.PICK" /> 273 * <category android:name="android.intent.category.DEFAULT" /> 274 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 275 * </intent-filter> 276 * <intent-filter> 277 * <action android:name="android.intent.action.GET_CONTENT" /> 278 * <category android:name="android.intent.category.DEFAULT" /> 279 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 280 * </intent-filter> 281 * </activity> 282 * 283 * <activity class=".NoteEditor" android:label="@string/title_note"> 284 * <intent-filter android:label="@string/resolve_edit"> 285 * <action android:name="android.intent.action.VIEW" /> 286 * <action android:name="android.intent.action.EDIT" /> 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 * 291 * <intent-filter> 292 * <action android:name="android.intent.action.INSERT" /> 293 * <category android:name="android.intent.category.DEFAULT" /> 294 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 295 * </intent-filter> 296 * 297 * </activity> 298 * 299 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 300 * android:theme="@android:style/Theme.Dialog"> 301 * <intent-filter android:label="@string/resolve_title"> 302 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 303 * <category android:name="android.intent.category.DEFAULT" /> 304 * <category android:name="android.intent.category.ALTERNATIVE" /> 305 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 306 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 307 * </intent-filter> 308 * </activity> 309 * 310 * </application> 311 * </manifest></pre> 312 * 313 * <p>The first activity, 314 * <code>com.android.notepad.NotesList</code>, serves as our main 315 * entry into the app. It can do three things as described by its three intent 316 * templates: 317 * <ol> 318 * <li><pre> 319 * <intent-filter> 320 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 321 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 322 * </intent-filter></pre> 323 * <p>This provides a top-level entry into the NotePad application: the standard 324 * MAIN action is a main entry point (not requiring any other information in 325 * the Intent), and the LAUNCHER category says that this entry point should be 326 * listed in the application launcher.</p> 327 * <li><pre> 328 * <intent-filter> 329 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 330 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 331 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 332 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 333 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 334 * </intent-filter></pre> 335 * <p>This declares the things that the activity can do on a directory of 336 * notes. The type being supported is given with the <type> tag, where 337 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 338 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 339 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 340 * The activity allows the user to view or edit the directory of data (via 341 * the VIEW and EDIT actions), or to pick a particular note and return it 342 * to the caller (via the PICK action). Note also the DEFAULT category 343 * supplied here: this is <em>required</em> for the 344 * {@link Context#startActivity Context.startActivity} method to resolve your 345 * activity when its component name is not explicitly specified.</p> 346 * <li><pre> 347 * <intent-filter> 348 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 349 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 350 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 351 * </intent-filter></pre> 352 * <p>This filter describes the ability return to the caller a note selected by 353 * the user without needing to know where it came from. The data type 354 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 355 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 356 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 357 * The GET_CONTENT action is similar to the PICK action, where the activity 358 * will return to its caller a piece of data selected by the user. Here, 359 * however, the caller specifies the type of data they desire instead of 360 * the type of data the user will be picking from.</p> 361 * </ol> 362 * 363 * <p>Given these capabilities, the following intents will resolve to the 364 * NotesList activity:</p> 365 * 366 * <ul> 367 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 368 * activities that can be used as top-level entry points into an 369 * application.</p> 370 * <li> <p><b>{ action=android.app.action.MAIN, 371 * category=android.app.category.LAUNCHER }</b> is the actual intent 372 * used by the Launcher to populate its top-level list.</p> 373 * <li> <p><b>{ action=android.intent.action.VIEW 374 * data=content://com.google.provider.NotePad/notes }</b> 375 * displays a list of all the notes under 376 * "content://com.google.provider.NotePad/notes", which 377 * the user can browse through and see the details on.</p> 378 * <li> <p><b>{ action=android.app.action.PICK 379 * data=content://com.google.provider.NotePad/notes }</b> 380 * provides a list of the notes under 381 * "content://com.google.provider.NotePad/notes", from which 382 * the user can pick a note whose data URL is returned back to the caller.</p> 383 * <li> <p><b>{ action=android.app.action.GET_CONTENT 384 * type=vnd.android.cursor.item/vnd.google.note }</b> 385 * is similar to the pick action, but allows the caller to specify the 386 * kind of data they want back so that the system can find the appropriate 387 * activity to pick something of that data type.</p> 388 * </ul> 389 * 390 * <p>The second activity, 391 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 392 * note entry and allows them to edit it. It can do two things as described 393 * by its two intent templates: 394 * <ol> 395 * <li><pre> 396 * <intent-filter android:label="@string/resolve_edit"> 397 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 398 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 399 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 400 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 401 * </intent-filter></pre> 402 * <p>The first, primary, purpose of this activity is to let the user interact 403 * with a single note, as decribed by the MIME type 404 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 405 * either VIEW a note or allow the user to EDIT it. Again we support the 406 * DEFAULT category to allow the activity to be launched without explicitly 407 * specifying its component.</p> 408 * <li><pre> 409 * <intent-filter> 410 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 411 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 412 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 413 * </intent-filter></pre> 414 * <p>The secondary use of this activity is to insert a new note entry into 415 * an existing directory of notes. This is used when the user creates a new 416 * note: the INSERT action is executed on the directory of notes, causing 417 * this activity to run and have the user create the new note data which 418 * it then adds to the content provider.</p> 419 * </ol> 420 * 421 * <p>Given these capabilities, the following intents will resolve to the 422 * NoteEditor activity:</p> 423 * 424 * <ul> 425 * <li> <p><b>{ action=android.intent.action.VIEW 426 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 427 * shows the user the content of note <var>{ID}</var>.</p> 428 * <li> <p><b>{ action=android.app.action.EDIT 429 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 430 * allows the user to edit the content of note <var>{ID}</var>.</p> 431 * <li> <p><b>{ action=android.app.action.INSERT 432 * data=content://com.google.provider.NotePad/notes }</b> 433 * creates a new, empty note in the notes list at 434 * "content://com.google.provider.NotePad/notes" 435 * and allows the user to edit it. If they keep their changes, the URI 436 * of the newly created note is returned to the caller.</p> 437 * </ul> 438 * 439 * <p>The last activity, 440 * <code>com.android.notepad.TitleEditor</code>, allows the user to 441 * edit the title of a note. This could be implemented as a class that the 442 * application directly invokes (by explicitly setting its component in 443 * the Intent), but here we show a way you can publish alternative 444 * operations on existing data:</p> 445 * 446 * <pre> 447 * <intent-filter android:label="@string/resolve_title"> 448 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 449 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 450 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 451 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 452 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 453 * </intent-filter></pre> 454 * 455 * <p>In the single intent template here, we 456 * have created our own private action called 457 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 458 * edit the title of a note. It must be invoked on a specific note 459 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 460 * view and edit actions, but here displays and edits the title contained 461 * in the note data. 462 * 463 * <p>In addition to supporting the default category as usual, our title editor 464 * also supports two other standard categories: ALTERNATIVE and 465 * SELECTED_ALTERNATIVE.
