It 61 * can be used with {@link Context#startActivity(Intent) startActivity} to 62 * launch an {@link android.app.Activity}, 63 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 64 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 65 * and {@link android.content.Context#startService} or 66 * {@link android.content.Context#bindService} to communicate with a 67 * background {@link android.app.Service}. 68 * 69 * <p>An Intent provides a facility for performing late runtime binding between the code in 70 * different applications. Its most significant use is in the launching of activities, where it 71 * can be thought of as the glue between activities. It is basically a passive data structure 72 * holding an abstract description of an action to be performed.</p> 73 * 74 * <div class="special reference"> 75 * <h3>Developer Guides</h3> 76 * <p>For information about how to create and resolve intents, read the 77 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 78 * developer guide.</p> 79 * </div> 80 * 81 * <a name="IntentStructure"></a> 82 * <h3>Intent Structure</h3> 83 * <p>The primary pieces of information in an intent are:</p> 84 * 85 * <ul> 86 * <li> <p><b>action</b> -- The general action to be performed, such as 87 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 88 * etc.</p> 89 * </li> 90 * <li> <p><b>data</b> -- The data to operate on, such as a person record 91 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 92 * </li> 93 * </ul> 94 * 95 * 96 * <p>Some examples of action/data pairs are:</p> 97 * 98 * <ul> 99 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 100 * information about the person whose identifier is "1".</p> 101 * </li> 102 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 103 * the phone dialer with the person filled in.</p> 104 * </li> 105 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 106 * the phone dialer with the given number filled in. Note how the 107 * VIEW action does what what is considered the most reasonable thing for 108 * a particular URI.</p> 109 * </li> 110 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 111 * the phone dialer with the given number filled in.</p> 112 * </li> 113 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 114 * information about the person whose identifier is "1".</p> 115 * </li> 116 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 117 * a list of people, which the user can browse through. This example is a 118 * typical top-level entry into the Contacts application, showing you the 119 * list of people. Selecting a particular person to view would result in a 120 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 121 * being used to start an activity to display that person.</p> 122 * </li> 123 * </ul> 124 * 125 * <p>In addition to these primary attributes, there are a number of secondary 126 * attributes that you can also include with an intent:</p> 127 * 128 * <ul> 129 * <li> <p><b>category</b> -- Gives additional information about the action 130 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 131 * appear in the Launcher as a top-level application, while 132 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 133 * of alternative actions the user can perform on a piece of data.</p> 134 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 135 * intent data. Normally the type is inferred from the data itself. 136 * By setting this attribute, you disable that evaluation and force 137 * an explicit type.</p> 138 * <li> <p><b>component</b> -- Specifies an explicit name of a component 139 * class to use for the intent. Normally this is determined by looking 140 * at the other information in the intent (the action, data/type, and 141 * categories) and matching that with a component that can handle it. 142 * If this attribute is set then none of the evaluation is performed, 143 * and this component is used exactly as is. By specifying this attribute, 144 * all of the other Intent attributes become optional.</p> 145 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 146 * This can be used to provide extended information to the component. 147 * For example, if we have a action to send an e-mail message, we could 148 * also include extra pieces of data here to supply a subject, body, 149 * etc.</p> 150 * </ul> 151 * 152 * <p>Here are some examples of other operations you can specify as intents 153 * using these additional parameters:</p> 154 * 155 * <ul> 156 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 157 * Launch the home screen.</p> 158 * </li> 159 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 160 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 161 * vnd.android.cursor.item/phone}</i></b> 162 * -- Display the list of people's phone numbers, allowing the user to 163 * browse through them and pick one and return it to the parent activity.</p> 164 * </li> 165 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 166 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 167 * -- Display all pickers for data that can be opened with 168 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 169 * allowing the user to pick one of them and then some data inside of it 170 * and returning the resulting URI to the caller. This can be used, 171 * for example, in an e-mail application to allow the user to pick some 172 * data to include as an attachment.</p> 173 * </li> 174 * </ul> 175 * 176 * <p>There are a variety of standard Intent action and category constants 177 * defined in the Intent class, but applications can also define their own. 178 * These strings use java style scoping, to ensure they are unique -- for 179 * example, the standard {@link #ACTION_VIEW} is called 180 * "android.intent.action.VIEW".</p> 181 * 182 * <p>Put together, the set of actions, data types, categories, and extra data 183 * defines a language for the system allowing for the expression of phrases 184 * such as "call john smith's cell". As applications are added to the system, 185 * they can extend this language by adding new actions, types, and categories, or 186 * they can modify the behavior of existing phrases by supplying their own 187 * activities that handle them.</p> 188 * 189 * <a name="IntentResolution"></a> 190 * <h3>Intent Resolution</h3> 191 * 192 * <p>There are two primary forms of intents you will use. 193 * 194 * <ul> 195 * <li> <p><b>Explicit Intents</b> have specified a component (via 196 * {@link #setComponent} or {@link #setClass}), which provides the exact 197 * class to be run. Often these will not include any other information, 198 * simply being a way for an application to launch various internal 199 * activities it has as the user interacts with the application. 200 * 201 * <li> <p><b>Implicit Intents</b> have not specified a component; 202 * instead, they must include enough information for the system to 203 * determine which of the available components is best to run for that 204 * intent. 205 * </ul> 206 * 207 * <p>When using implicit intents, given such an arbitrary intent we need to 208 * know what to do with it. This is handled by the process of <em>Intent 209 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 210 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 211 * more activities/receivers) that can handle it.</p> 212 * 213 * <p>The intent resolution mechanism basically revolves around matching an 214 * Intent against all of the <intent-filter> descriptions in the 215 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 216 * objects explicitly registered with {@link Context#registerReceiver}.) More 217 * details on this can be found in the documentation on the {@link 218 * IntentFilter} class.</p> 219 * 220 * <p>There are three pieces of information in the Intent that are used for 221 * resolution: the action, type, and category. Using this information, a query 222 * is done on the {@link PackageManager} for a component that can handle the 223 * intent. The appropriate component is determined based on the intent 224 * information supplied in the <code>AndroidManifest.xml</code> file as 225 * follows:</p> 226 * 227 * <ul> 228 * <li> <p>The <b>action</b>, if given, must be listed by the component as 229 * one it handles.</p> 230 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 231 * already supplied in the Intent. Like the action, if a type is 232 * included in the intent (either explicitly or implicitly in its 233 * data), then this must be listed by the component as one it handles.</p> 234 * <li> For data that is not a <code>content:</code> URI and where no explicit 235 * type is included in the Intent, instead the <b>scheme</b> of the 236 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 237 * considered. Again like the action, if we are matching a scheme it 238 * must be listed by the component as one it can handle. 239 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 240 * by the activity as categories it handles. That is, if you include 241 * the categories {@link #CATEGORY_LAUNCHER} and 242 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 243 * with an intent that lists <em>both</em> of those categories. 244 * Activities will very often need to support the 245 * {@link #CATEGORY_DEFAULT} so that they can be found by 246 * {@link Context#startActivity Context.startActivity()}.</p> 247 * </ul> 248 * 249 * <p>For example, consider the Note Pad sample application that 250 * allows user to browse through a list of notes data and view details about 251 * individual items. Text in italics indicate places were you would replace a 252 * name with one specific to your own package.</p> 253 * 254 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 255 * package="<i>com.android.notepad</i>"> 256 * <application android:icon="@drawable/app_notes" 257 * android:label="@string/app_name"> 258 * 259 * <provider class=".NotePadProvider" 260 * android:authorities="<i>com.google.provider.NotePad</i>" /> 261 * 262 * <activity class=".NotesList" android:label="@string/title_notes_list"> 263 * <intent-filter> 264 * <action android:name="android.intent.action.MAIN" /> 265 * <category android:name="android.intent.category.LAUNCHER" /> 266 * </intent-filter> 267 * <intent-filter> 268 * <action android:name="android.intent.action.VIEW" /> 269 * <action android:name="android.intent.action.EDIT" /> 270 * <action android:name="android.intent.action.PICK" /> 271 * <category android:name="android.intent.category.DEFAULT" /> 272 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 273 * </intent-filter> 274 * <intent-filter> 275 * <action android:name="android.intent.action.GET_CONTENT" /> 276 * <category android:name="android.intent.category.DEFAULT" /> 277 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 278 * </intent-filter> 279 * </activity> 280 * 281 * <activity class=".NoteEditor" android:label="@string/title_note"> 282 * <intent-filter android:label="@string/resolve_edit"> 283 * <action android:name="android.intent.action.VIEW" /> 284 * <action android:name="android.intent.action.EDIT" /> 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 * 289 * <intent-filter> 290 * <action android:name="android.intent.action.INSERT" /> 291 * <category android:name="android.intent.category.DEFAULT" /> 292 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 293 * </intent-filter> 294 * 295 * </activity> 296 * 297 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 298 * android:theme="@android:style/Theme.Dialog"> 299 * <intent-filter android:label="@string/resolve_title"> 300 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 301 * <category android:name="android.intent.category.DEFAULT" /> 302 * <category android:name="android.intent.category.ALTERNATIVE" /> 303 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 304 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 305 * </intent-filter> 306 * </activity> 307 * 308 * </application> 309 * </manifest></pre> 310 * 311 * <p>The first activity, 312 * <code>com.android.notepad.NotesList</code>, serves as our main 313 * entry into the app. It can do three things as described by its three intent 314 * templates: 315 * <ol> 316 * <li><pre> 317 * <intent-filter> 318 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 319 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 320 * </intent-filter></pre> 321 * <p>This provides a top-level entry into the NotePad application: the standard 322 * MAIN action is a main entry point (not requiring any other information in 323 * the Intent), and the LAUNCHER category says that this entry point should be 324 * listed in the application launcher.</p> 325 * <li><pre> 326 * <intent-filter> 327 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 328 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 329 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 330 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 331 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 332 * </intent-filter></pre> 333 * <p>This declares the things that the activity can do on a directory of 334 * notes. The type being supported is given with the <type> tag, where 335 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 336 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 337 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 338 * The activity allows the user to view or edit the directory of data (via 339 * the VIEW and EDIT actions), or to pick a particular note and return it 340 * to the caller (via the PICK action). Note also the DEFAULT category 341 * supplied here: this is <em>required</em> for the 342 * {@link Context#startActivity Context.startActivity} method to resolve your 343 * activity when its component name is not explicitly specified.</p> 344 * <li><pre> 345 * <intent-filter> 346 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 347 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 348 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 349 * </intent-filter></pre> 350 * <p>This filter describes the ability return to the caller a note selected by 351 * the user without needing to know where it came from. The data type 352 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 353 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 354 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 355 * The GET_CONTENT action is similar to the PICK action, where the activity 356 * will return to its caller a piece of data selected by the user. Here, 357 * however, the caller specifies the type of data they desire instead of 358 * the type of data the user will be picking from.</p> 359 * </ol> 360 * 361 * <p>Given these capabilities, the following intents will resolve to the 362 * NotesList activity:</p> 363 * 364 * <ul> 365 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 366 * activities that can be used as top-level entry points into an 367 * application.</p> 368 * <li> <p><b>{ action=android.app.action.MAIN, 369 * category=android.app.category.LAUNCHER }</b> is the actual intent 370 * used by the Launcher to populate its top-level list.</p> 371 * <li> <p><b>{ action=android.intent.action.VIEW 372 * data=content://com.google.provider.NotePad/notes }</b> 373 * displays a list of all the notes under 374 * "content://com.google.provider.NotePad/notes", which 375 * the user can browse through and see the details on.</p> 376 * <li> <p><b>{ action=android.app.action.PICK 377 * data=content://com.google.provider.NotePad/notes }</b> 378 * provides a list of the notes under 379 * "content://com.google.provider.NotePad/notes", from which 380 * the user can pick a note whose data URL is returned back to the caller.</p> 381 * <li> <p><b>{ action=android.app.action.GET_CONTENT 382 * type=vnd.android.cursor.item/vnd.google.note }</b> 383 * is similar to the pick action, but allows the caller to specify the 384 * kind of data they want back so that the system can find the appropriate 385 * activity to pick something of that data type.</p> 386 * </ul> 387 * 388 * <p>The second activity, 389 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 390 * note entry and allows them to edit it. It can do two things as described 391 * by its two intent templates: 392 * <ol> 393 * <li><pre> 394 * <intent-filter android:label="@string/resolve_edit"> 395 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 396 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 397 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 398 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 399 * </intent-filter></pre> 400 * <p>The first, primary, purpose of this activity is to let the user interact 401 * with a single note, as decribed by the MIME type 402 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 403 * either VIEW a note or allow the user to EDIT it. Again we support the 404 * DEFAULT category to allow the activity to be launched without explicitly 405 * specifying its component.</p> 406 * <li><pre> 407 * <intent-filter> 408 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 409 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 410 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 411 * </intent-filter></pre> 412 * <p>The secondary use of this activity is to insert a new note entry into 413 * an existing directory of notes. This is used when the user creates a new 414 * note: the INSERT action is executed on the directory of notes, causing 415 * this activity to run and have the user create the new note data which 416 * it then adds to the content provider.</p> 417 * </ol> 418 * 419 * <p>Given these capabilities, the following intents will resolve to the 420 * NoteEditor activity:</p> 421 * 422 * <ul> 423 * <li> <p><b>{ action=android.intent.action.VIEW 424 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 425 * shows the user the content of note <var>{ID}</var>.</p> 426 * <li> <p><b>{ action=android.app.action.EDIT 427 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 428 * allows the user to edit the content of note <var>{ID}</var>.</p> 429 * <li> <p><b>{ action=android.app.action.INSERT 430 * data=content://com.google.provider.NotePad/notes }</b> 431 * creates a new, empty note in the notes list at 432 * "content://com.google.provider.NotePad/notes" 433 * and allows the user to edit it. If they keep their changes, the URI 434 * of the newly created note is returned to the caller.</p> 435 * </ul> 436 * 437 * <p>The last activity, 438 * <code>com.android.notepad.TitleEditor</code>, allows the user to 439 * edit the title of a note. This could be implemented as a class that the 440 * application directly invokes (by explicitly setting its component in 441 * the Intent), but here we show a way you can publish alternative 442 * operations on existing data:</p> 443 * 444 * <pre> 445 * <intent-filter android:label="@string/resolve_title"> 446 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 447 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 448 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 449 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 450 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 451 * </intent-filter></pre> 452 * 453 * <p>In the single intent template here, we 454 * have created our own private action called 455 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 456 * edit the title of a note. It must be invoked on a specific note 457 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 458 * view and edit actions, but here displays and edits the title contained 459 * in the note data. 460 * 461 * <p>In addition to supporting the default category as usual, our title editor 462 * also supports two other standard categories: ALTERNATIVE and 463 * SELECTED_ALTERNATIVE.
