It 62 * can be used with {@link Context#startActivity(Intent) startActivity} to 63 * launch an {@link android.app.Activity}, 64 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 65 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 66 * and {@link android.content.Context#startService} or 67 * {@link android.content.Context#bindService} to communicate with a 68 * background {@link android.app.Service}. 69 * 70 * <p>An Intent provides a facility for performing late runtime binding between the code in 71 * different applications. Its most significant use is in the launching of activities, where it 72 * can be thought of as the glue between activities. It is basically a passive data structure 73 * holding an abstract description of an action to be performed.</p> 74 * 75 * <div class="special reference"> 76 * <h3>Developer Guides</h3> 77 * <p>For information about how to create and resolve intents, read the 78 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 79 * developer guide.</p> 80 * </div> 81 * 82 * <a name="IntentStructure"></a> 83 * <h3>Intent Structure</h3> 84 * <p>The primary pieces of information in an intent are:</p> 85 * 86 * <ul> 87 * <li> <p><b>action</b> -- The general action to be performed, such as 88 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 89 * etc.</p> 90 * </li> 91 * <li> <p><b>data</b> -- The data to operate on, such as a person record 92 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 93 * </li> 94 * </ul> 95 * 96 * 97 * <p>Some examples of action/data pairs are:</p> 98 * 99 * <ul> 100 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 101 * information about the person whose identifier is "1".</p> 102 * </li> 103 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 104 * the phone dialer with the person filled in.</p> 105 * </li> 106 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 107 * the phone dialer with the given number filled in. Note how the 108 * VIEW action does what what is considered the most reasonable thing for 109 * a particular URI.</p> 110 * </li> 111 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 112 * the phone dialer with the given number filled in.</p> 113 * </li> 114 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 115 * information about the person whose identifier is "1".</p> 116 * </li> 117 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 118 * a list of people, which the user can browse through. This example is a 119 * typical top-level entry into the Contacts application, showing you the 120 * list of people. Selecting a particular person to view would result in a 121 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 122 * being used to start an activity to display that person.</p> 123 * </li> 124 * </ul> 125 * 126 * <p>In addition to these primary attributes, there are a number of secondary 127 * attributes that you can also include with an intent:</p> 128 * 129 * <ul> 130 * <li> <p><b>category</b> -- Gives additional information about the action 131 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 132 * appear in the Launcher as a top-level application, while 133 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 134 * of alternative actions the user can perform on a piece of data.</p> 135 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 136 * intent data. Normally the type is inferred from the data itself. 137 * By setting this attribute, you disable that evaluation and force 138 * an explicit type.</p> 139 * <li> <p><b>component</b> -- Specifies an explicit name of a component 140 * class to use for the intent. Normally this is determined by looking 141 * at the other information in the intent (the action, data/type, and 142 * categories) and matching that with a component that can handle it. 143 * If this attribute is set then none of the evaluation is performed, 144 * and this component is used exactly as is. By specifying this attribute, 145 * all of the other Intent attributes become optional.</p> 146 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 147 * This can be used to provide extended information to the component. 148 * For example, if we have a action to send an e-mail message, we could 149 * also include extra pieces of data here to supply a subject, body, 150 * etc.</p> 151 * </ul> 152 * 153 * <p>Here are some examples of other operations you can specify as intents 154 * using these additional parameters:</p> 155 * 156 * <ul> 157 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 158 * Launch the home screen.</p> 159 * </li> 160 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 161 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 162 * vnd.android.cursor.item/phone}</i></b> 163 * -- Display the list of people's phone numbers, allowing the user to 164 * browse through them and pick one and return it to the parent activity.</p> 165 * </li> 166 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 167 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 168 * -- Display all pickers for data that can be opened with 169 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 170 * allowing the user to pick one of them and then some data inside of it 171 * and returning the resulting URI to the caller. This can be used, 172 * for example, in an e-mail application to allow the user to pick some 173 * data to include as an attachment.</p> 174 * </li> 175 * </ul> 176 * 177 * <p>There are a variety of standard Intent action and category constants 178 * defined in the Intent class, but applications can also define their own. 179 * These strings use java style scoping, to ensure they are unique -- for 180 * example, the standard {@link #ACTION_VIEW} is called 181 * "android.intent.action.VIEW".</p> 182 * 183 * <p>Put together, the set of actions, data types, categories, and extra data 184 * defines a language for the system allowing for the expression of phrases 185 * such as "call john smith's cell". As applications are added to the system, 186 * they can extend this language by adding new actions, types, and categories, or 187 * they can modify the behavior of existing phrases by supplying their own 188 * activities that handle them.</p> 189 * 190 * <a name="IntentResolution"></a> 191 * <h3>Intent Resolution</h3> 192 * 193 * <p>There are two primary forms of intents you will use. 194 * 195 * <ul> 196 * <li> <p><b>Explicit Intents</b> have specified a component (via 197 * {@link #setComponent} or {@link #setClass}), which provides the exact 198 * class to be run. Often these will not include any other information, 199 * simply being a way for an application to launch various internal 200 * activities it has as the user interacts with the application. 201 * 202 * <li> <p><b>Implicit Intents</b> have not specified a component; 203 * instead, they must include enough information for the system to 204 * determine which of the available components is best to run for that 205 * intent. 206 * </ul> 207 * 208 * <p>When using implicit intents, given such an arbitrary intent we need to 209 * know what to do with it. This is handled by the process of <em>Intent 210 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 211 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 212 * more activities/receivers) that can handle it.</p> 213 * 214 * <p>The intent resolution mechanism basically revolves around matching an 215 * Intent against all of the <intent-filter> descriptions in the 216 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 217 * objects explicitly registered with {@link Context#registerReceiver}.) More 218 * details on this can be found in the documentation on the {@link 219 * IntentFilter} class.</p> 220 * 221 * <p>There are three pieces of information in the Intent that are used for 222 * resolution: the action, type, and category. Using this information, a query 223 * is done on the {@link PackageManager} for a component that can handle the 224 * intent. The appropriate component is determined based on the intent 225 * information supplied in the <code>AndroidManifest.xml</code> file as 226 * follows:</p> 227 * 228 * <ul> 229 * <li> <p>The <b>action</b>, if given, must be listed by the component as 230 * one it handles.</p> 231 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 232 * already supplied in the Intent. Like the action, if a type is 233 * included in the intent (either explicitly or implicitly in its 234 * data), then this must be listed by the component as one it handles.</p> 235 * <li> For data that is not a <code>content:</code> URI and where no explicit 236 * type is included in the Intent, instead the <b>scheme</b> of the 237 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 238 * considered. Again like the action, if we are matching a scheme it 239 * must be listed by the component as one it can handle. 240 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 241 * by the activity as categories it handles. That is, if you include 242 * the categories {@link #CATEGORY_LAUNCHER} and 243 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 244 * with an intent that lists <em>both</em> of those categories. 245 * Activities will very often need to support the 246 * {@link #CATEGORY_DEFAULT} so that they can be found by 247 * {@link Context#startActivity Context.startActivity()}.</p> 248 * </ul> 249 * 250 * <p>For example, consider the Note Pad sample application that 251 * allows user to browse through a list of notes data and view details about 252 * individual items. Text in italics indicate places were you would replace a 253 * name with one specific to your own package.</p> 254 * 255 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 256 * package="<i>com.android.notepad</i>"> 257 * <application android:icon="@drawable/app_notes" 258 * android:label="@string/app_name"> 259 * 260 * <provider class=".NotePadProvider" 261 * android:authorities="<i>com.google.provider.NotePad</i>" /> 262 * 263 * <activity class=".NotesList" android:label="@string/title_notes_list"> 264 * <intent-filter> 265 * <action android:name="android.intent.action.MAIN" /> 266 * <category android:name="android.intent.category.LAUNCHER" /> 267 * </intent-filter> 268 * <intent-filter> 269 * <action android:name="android.intent.action.VIEW" /> 270 * <action android:name="android.intent.action.EDIT" /> 271 * <action android:name="android.intent.action.PICK" /> 272 * <category android:name="android.intent.category.DEFAULT" /> 273 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 274 * </intent-filter> 275 * <intent-filter> 276 * <action android:name="android.intent.action.GET_CONTENT" /> 277 * <category android:name="android.intent.category.DEFAULT" /> 278 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 279 * </intent-filter> 280 * </activity> 281 * 282 * <activity class=".NoteEditor" android:label="@string/title_note"> 283 * <intent-filter android:label="@string/resolve_edit"> 284 * <action android:name="android.intent.action.VIEW" /> 285 * <action android:name="android.intent.action.EDIT" /> 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 * 290 * <intent-filter> 291 * <action android:name="android.intent.action.INSERT" /> 292 * <category android:name="android.intent.category.DEFAULT" /> 293 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 294 * </intent-filter> 295 * 296 * </activity> 297 * 298 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 299 * android:theme="@android:style/Theme.Dialog"> 300 * <intent-filter android:label="@string/resolve_title"> 301 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 302 * <category android:name="android.intent.category.DEFAULT" /> 303 * <category android:name="android.intent.category.ALTERNATIVE" /> 304 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 305 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 306 * </intent-filter> 307 * </activity> 308 * 309 * </application> 310 * </manifest></pre> 311 * 312 * <p>The first activity, 313 * <code>com.android.notepad.NotesList</code>, serves as our main 314 * entry into the app. It can do three things as described by its three intent 315 * templates: 316 * <ol> 317 * <li><pre> 318 * <intent-filter> 319 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 320 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 321 * </intent-filter></pre> 322 * <p>This provides a top-level entry into the NotePad application: the standard 323 * MAIN action is a main entry point (not requiring any other information in 324 * the Intent), and the LAUNCHER category says that this entry point should be 325 * listed in the application launcher.</p> 326 * <li><pre> 327 * <intent-filter> 328 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 329 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 330 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 331 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 332 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 333 * </intent-filter></pre> 334 * <p>This declares the things that the activity can do on a directory of 335 * notes. The type being supported is given with the <type> tag, where 336 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 337 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 338 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 339 * The activity allows the user to view or edit the directory of data (via 340 * the VIEW and EDIT actions), or to pick a particular note and return it 341 * to the caller (via the PICK action). Note also the DEFAULT category 342 * supplied here: this is <em>required</em> for the 343 * {@link Context#startActivity Context.startActivity} method to resolve your 344 * activity when its component name is not explicitly specified.</p> 345 * <li><pre> 346 * <intent-filter> 347 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 348 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 349 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 350 * </intent-filter></pre> 351 * <p>This filter describes the ability return to the caller a note selected by 352 * the user without needing to know where it came from. The data type 353 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 354 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 355 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 356 * The GET_CONTENT action is similar to the PICK action, where the activity 357 * will return to its caller a piece of data selected by the user. Here, 358 * however, the caller specifies the type of data they desire instead of 359 * the type of data the user will be picking from.</p> 360 * </ol> 361 * 362 * <p>Given these capabilities, the following intents will resolve to the 363 * NotesList activity:</p> 364 * 365 * <ul> 366 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 367 * activities that can be used as top-level entry points into an 368 * application.</p> 369 * <li> <p><b>{ action=android.app.action.MAIN, 370 * category=android.app.category.LAUNCHER }</b> is the actual intent 371 * used by the Launcher to populate its top-level list.</p> 372 * <li> <p><b>{ action=android.intent.action.VIEW 373 * data=content://com.google.provider.NotePad/notes }</b> 374 * displays a list of all the notes under 375 * "content://com.google.provider.NotePad/notes", which 376 * the user can browse through and see the details on.</p> 377 * <li> <p><b>{ action=android.app.action.PICK 378 * data=content://com.google.provider.NotePad/notes }</b> 379 * provides a list of the notes under 380 * "content://com.google.provider.NotePad/notes", from which 381 * the user can pick a note whose data URL is returned back to the caller.</p> 382 * <li> <p><b>{ action=android.app.action.GET_CONTENT 383 * type=vnd.android.cursor.item/vnd.google.note }</b> 384 * is similar to the pick action, but allows the caller to specify the 385 * kind of data they want back so that the system can find the appropriate 386 * activity to pick something of that data type.</p> 387 * </ul> 388 * 389 * <p>The second activity, 390 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 391 * note entry and allows them to edit it. It can do two things as described 392 * by its two intent templates: 393 * <ol> 394 * <li><pre> 395 * <intent-filter android:label="@string/resolve_edit"> 396 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 397 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 398 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 399 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 400 * </intent-filter></pre> 401 * <p>The first, primary, purpose of this activity is to let the user interact 402 * with a single note, as decribed by the MIME type 403 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 404 * either VIEW a note or allow the user to EDIT it. Again we support the 405 * DEFAULT category to allow the activity to be launched without explicitly 406 * specifying its component.</p> 407 * <li><pre> 408 * <intent-filter> 409 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 410 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 411 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 412 * </intent-filter></pre> 413 * <p>The secondary use of this activity is to insert a new note entry into 414 * an existing directory of notes. This is used when the user creates a new 415 * note: the INSERT action is executed on the directory of notes, causing 416 * this activity to run and have the user create the new note data which 417 * it then adds to the content provider.</p> 418 * </ol> 419 * 420 * <p>Given these capabilities, the following intents will resolve to the 421 * NoteEditor activity:</p> 422 * 423 * <ul> 424 * <li> <p><b>{ action=android.intent.action.VIEW 425 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 426 * shows the user the content of note <var>{ID}</var>.</p> 427 * <li> <p><b>{ action=android.app.action.EDIT 428 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 429 * allows the user to edit the content of note <var>{ID}</var>.</p> 430 * <li> <p><b>{ action=android.app.action.INSERT 431 * data=content://com.google.provider.NotePad/notes }</b> 432 * creates a new, empty note in the notes list at 433 * "content://com.google.provider.NotePad/notes" 434 * and allows the user to edit it. If they keep their changes, the URI 435 * of the newly created note is returned to the caller.</p> 436 * </ul> 437 * 438 * <p>The last activity, 439 * <code>com.android.notepad.TitleEditor</code>, allows the user to 440 * edit the title of a note. This could be implemented as a class that the 441 * application directly invokes (by explicitly setting its component in 442 * the Intent), but here we show a way you can publish alternative 443 * operations on existing data:</p> 444 * 445 * <pre> 446 * <intent-filter android:label="@string/resolve_title"> 447 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 448 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 449 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 450 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 451 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 452 * </intent-filter></pre> 453 * 454 * <p>In the single intent template here, we 455 * have created our own private action called 456 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 457 * edit the title of a note. It must be invoked on a specific note 458 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 459 * view and edit actions, but here displays and edits the title contained 460 * in the note data. 461 * 462 * <p>In addition to supporting the default category as usual, our title editor 463 * also supports two other standard categories: ALTERNATIVE and 464 * SELECTED_ALTERNATIVE.
