It 59 * can be used with {@link Context#startActivity(Intent) startActivity} to 60 * launch an {@link android.app.Activity}, 61 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 62 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 63 * and {@link android.content.Context#startService} or 64 * {@link android.content.Context#bindService} to communicate with a 65 * background {@link android.app.Service}. 66 * 67 * <p>An Intent provides a facility for performing late runtime binding between the code in 68 * different applications. Its most significant use is in the launching of activities, where it 69 * can be thought of as the glue between activities. It is basically a passive data structure 70 * holding an abstract description of an action to be performed.</p> 71 * 72 * <div class="special reference"> 73 * <h3>Developer Guides</h3> 74 * <p>For information about how to create and resolve intents, read the 75 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 76 * developer guide.</p> 77 * </div> 78 * 79 * <a name="IntentStructure"></a> 80 * <h3>Intent Structure</h3> 81 * <p>The primary pieces of information in an intent are:</p> 82 * 83 * <ul> 84 * <li> <p><b>action</b> -- The general action to be performed, such as 85 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 86 * etc.</p> 87 * </li> 88 * <li> <p><b>data</b> -- The data to operate on, such as a person record 89 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 90 * </li> 91 * </ul> 92 * 93 * 94 * <p>Some examples of action/data pairs are:</p> 95 * 96 * <ul> 97 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 98 * information about the person whose identifier is "1".</p> 99 * </li> 100 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 101 * the phone dialer with the person filled in.</p> 102 * </li> 103 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 104 * the phone dialer with the given number filled in. Note how the 105 * VIEW action does what what is considered the most reasonable thing for 106 * a particular URI.</p> 107 * </li> 108 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 109 * the phone dialer with the given number filled in.</p> 110 * </li> 111 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 112 * information about the person whose identifier is "1".</p> 113 * </li> 114 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 115 * a list of people, which the user can browse through. This example is a 116 * typical top-level entry into the Contacts application, showing you the 117 * list of people. Selecting a particular person to view would result in a 118 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 119 * being used to start an activity to display that person.</p> 120 * </li> 121 * </ul> 122 * 123 * <p>In addition to these primary attributes, there are a number of secondary 124 * attributes that you can also include with an intent:</p> 125 * 126 * <ul> 127 * <li> <p><b>category</b> -- Gives additional information about the action 128 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 129 * appear in the Launcher as a top-level application, while 130 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 131 * of alternative actions the user can perform on a piece of data.</p> 132 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 133 * intent data. Normally the type is inferred from the data itself. 134 * By setting this attribute, you disable that evaluation and force 135 * an explicit type.</p> 136 * <li> <p><b>component</b> -- Specifies an explicit name of a component 137 * class to use for the intent. Normally this is determined by looking 138 * at the other information in the intent (the action, data/type, and 139 * categories) and matching that with a component that can handle it. 140 * If this attribute is set then none of the evaluation is performed, 141 * and this component is used exactly as is. By specifying this attribute, 142 * all of the other Intent attributes become optional.</p> 143 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 144 * This can be used to provide extended information to the component. 145 * For example, if we have a action to send an e-mail message, we could 146 * also include extra pieces of data here to supply a subject, body, 147 * etc.</p> 148 * </ul> 149 * 150 * <p>Here are some examples of other operations you can specify as intents 151 * using these additional parameters:</p> 152 * 153 * <ul> 154 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 155 * Launch the home screen.</p> 156 * </li> 157 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 158 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 159 * vnd.android.cursor.item/phone}</i></b> 160 * -- Display the list of people's phone numbers, allowing the user to 161 * browse through them and pick one and return it to the parent activity.</p> 162 * </li> 163 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 164 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 165 * -- Display all pickers for data that can be opened with 166 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 167 * allowing the user to pick one of them and then some data inside of it 168 * and returning the resulting URI to the caller. This can be used, 169 * for example, in an e-mail application to allow the user to pick some 170 * data to include as an attachment.</p> 171 * </li> 172 * </ul> 173 * 174 * <p>There are a variety of standard Intent action and category constants 175 * defined in the Intent class, but applications can also define their own. 176 * These strings use java style scoping, to ensure they are unique -- for 177 * example, the standard {@link #ACTION_VIEW} is called 178 * "android.intent.action.VIEW".</p> 179 * 180 * <p>Put together, the set of actions, data types, categories, and extra data 181 * defines a language for the system allowing for the expression of phrases 182 * such as "call john smith's cell". As applications are added to the system, 183 * they can extend this language by adding new actions, types, and categories, or 184 * they can modify the behavior of existing phrases by supplying their own 185 * activities that handle them.</p> 186 * 187 * <a name="IntentResolution"></a> 188 * <h3>Intent Resolution</h3> 189 * 190 * <p>There are two primary forms of intents you will use. 191 * 192 * <ul> 193 * <li> <p><b>Explicit Intents</b> have specified a component (via 194 * {@link #setComponent} or {@link #setClass}), which provides the exact 195 * class to be run. Often these will not include any other information, 196 * simply being a way for an application to launch various internal 197 * activities it has as the user interacts with the application. 198 * 199 * <li> <p><b>Implicit Intents</b> have not specified a component; 200 * instead, they must include enough information for the system to 201 * determine which of the available components is best to run for that 202 * intent. 203 * </ul> 204 * 205 * <p>When using implicit intents, given such an arbitrary intent we need to 206 * know what to do with it. This is handled by the process of <em>Intent 207 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 208 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 209 * more activities/receivers) that can handle it.</p> 210 * 211 * <p>The intent resolution mechanism basically revolves around matching an 212 * Intent against all of the <intent-filter> descriptions in the 213 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 214 * objects explicitly registered with {@link Context#registerReceiver}.) More 215 * details on this can be found in the documentation on the {@link 216 * IntentFilter} class.</p> 217 * 218 * <p>There are three pieces of information in the Intent that are used for 219 * resolution: the action, type, and category. Using this information, a query 220 * is done on the {@link PackageManager} for a component that can handle the 221 * intent. The appropriate component is determined based on the intent 222 * information supplied in the <code>AndroidManifest.xml</code> file as 223 * follows:</p> 224 * 225 * <ul> 226 * <li> <p>The <b>action</b>, if given, must be listed by the component as 227 * one it handles.</p> 228 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 229 * already supplied in the Intent. Like the action, if a type is 230 * included in the intent (either explicitly or implicitly in its 231 * data), then this must be listed by the component as one it handles.</p> 232 * <li> For data that is not a <code>content:</code> URI and where no explicit 233 * type is included in the Intent, instead the <b>scheme</b> of the 234 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 235 * considered. Again like the action, if we are matching a scheme it 236 * must be listed by the component as one it can handle. 237 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 238 * by the activity as categories it handles. That is, if you include 239 * the categories {@link #CATEGORY_LAUNCHER} and 240 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 241 * with an intent that lists <em>both</em> of those categories. 242 * Activities will very often need to support the 243 * {@link #CATEGORY_DEFAULT} so that they can be found by 244 * {@link Context#startActivity Context.startActivity()}.</p> 245 * </ul> 246 * 247 * <p>For example, consider the Note Pad sample application that 248 * allows user to browse through a list of notes data and view details about 249 * individual items. Text in italics indicate places were you would replace a 250 * name with one specific to your own package.</p> 251 * 252 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 253 * package="<i>com.android.notepad</i>"> 254 * <application android:icon="@drawable/app_notes" 255 * android:label="@string/app_name"> 256 * 257 * <provider class=".NotePadProvider" 258 * android:authorities="<i>com.google.provider.NotePad</i>" /> 259 * 260 * <activity class=".NotesList" android:label="@string/title_notes_list"> 261 * <intent-filter> 262 * <action android:name="android.intent.action.MAIN" /> 263 * <category android:name="android.intent.category.LAUNCHER" /> 264 * </intent-filter> 265 * <intent-filter> 266 * <action android:name="android.intent.action.VIEW" /> 267 * <action android:name="android.intent.action.EDIT" /> 268 * <action android:name="android.intent.action.PICK" /> 269 * <category android:name="android.intent.category.DEFAULT" /> 270 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 271 * </intent-filter> 272 * <intent-filter> 273 * <action android:name="android.intent.action.GET_CONTENT" /> 274 * <category android:name="android.intent.category.DEFAULT" /> 275 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 276 * </intent-filter> 277 * </activity> 278 * 279 * <activity class=".NoteEditor" android:label="@string/title_note"> 280 * <intent-filter android:label="@string/resolve_edit"> 281 * <action android:name="android.intent.action.VIEW" /> 282 * <action android:name="android.intent.action.EDIT" /> 283 * <category android:name="android.intent.category.DEFAULT" /> 284 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 285 * </intent-filter> 286 * 287 * <intent-filter> 288 * <action android:name="android.intent.action.INSERT" /> 289 * <category android:name="android.intent.category.DEFAULT" /> 290 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 291 * </intent-filter> 292 * 293 * </activity> 294 * 295 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 296 * android:theme="@android:style/Theme.Dialog"> 297 * <intent-filter android:label="@string/resolve_title"> 298 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 299 * <category android:name="android.intent.category.DEFAULT" /> 300 * <category android:name="android.intent.category.ALTERNATIVE" /> 301 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 302 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 303 * </intent-filter> 304 * </activity> 305 * 306 * </application> 307 * </manifest></pre> 308 * 309 * <p>The first activity, 310 * <code>com.android.notepad.NotesList</code>, serves as our main 311 * entry into the app. It can do three things as described by its three intent 312 * templates: 313 * <ol> 314 * <li><pre> 315 * <intent-filter> 316 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 317 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 318 * </intent-filter></pre> 319 * <p>This provides a top-level entry into the NotePad application: the standard 320 * MAIN action is a main entry point (not requiring any other information in 321 * the Intent), and the LAUNCHER category says that this entry point should be 322 * listed in the application launcher.</p> 323 * <li><pre> 324 * <intent-filter> 325 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 326 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 327 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 328 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 329 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 330 * </intent-filter></pre> 331 * <p>This declares the things that the activity can do on a directory of 332 * notes. The type being supported is given with the <type> tag, where 333 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 334 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 335 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 336 * The activity allows the user to view or edit the directory of data (via 337 * the VIEW and EDIT actions), or to pick a particular note and return it 338 * to the caller (via the PICK action). Note also the DEFAULT category 339 * supplied here: this is <em>required</em> for the 340 * {@link Context#startActivity Context.startActivity} method to resolve your 341 * activity when its component name is not explicitly specified.</p> 342 * <li><pre> 343 * <intent-filter> 344 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 345 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 346 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 347 * </intent-filter></pre> 348 * <p>This filter describes the ability return to the caller a note selected by 349 * the user without needing to know where it came from. The data type 350 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 351 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 352 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 353 * The GET_CONTENT action is similar to the PICK action, where the activity 354 * will return to its caller a piece of data selected by the user. Here, 355 * however, the caller specifies the type of data they desire instead of 356 * the type of data the user will be picking from.</p> 357 * </ol> 358 * 359 * <p>Given these capabilities, the following intents will resolve to the 360 * NotesList activity:</p> 361 * 362 * <ul> 363 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 364 * activities that can be used as top-level entry points into an 365 * application.</p> 366 * <li> <p><b>{ action=android.app.action.MAIN, 367 * category=android.app.category.LAUNCHER }</b> is the actual intent 368 * used by the Launcher to populate its top-level list.</p> 369 * <li> <p><b>{ action=android.intent.action.VIEW 370 * data=content://com.google.provider.NotePad/notes }</b> 371 * displays a list of all the notes under 372 * "content://com.google.provider.NotePad/notes", which 373 * the user can browse through and see the details on.</p> 374 * <li> <p><b>{ action=android.app.action.PICK 375 * data=content://com.google.provider.NotePad/notes }</b> 376 * provides a list of the notes under 377 * "content://com.google.provider.NotePad/notes", from which 378 * the user can pick a note whose data URL is returned back to the caller.</p> 379 * <li> <p><b>{ action=android.app.action.GET_CONTENT 380 * type=vnd.android.cursor.item/vnd.google.note }</b> 381 * is similar to the pick action, but allows the caller to specify the 382 * kind of data they want back so that the system can find the appropriate 383 * activity to pick something of that data type.</p> 384 * </ul> 385 * 386 * <p>The second activity, 387 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 388 * note entry and allows them to edit it. It can do two things as described 389 * by its two intent templates: 390 * <ol> 391 * <li><pre> 392 * <intent-filter android:label="@string/resolve_edit"> 393 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 394 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 395 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 396 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 397 * </intent-filter></pre> 398 * <p>The first, primary, purpose of this activity is to let the user interact 399 * with a single note, as decribed by the MIME type 400 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 401 * either VIEW a note or allow the user to EDIT it. Again we support the 402 * DEFAULT category to allow the activity to be launched without explicitly 403 * specifying its component.</p> 404 * <li><pre> 405 * <intent-filter> 406 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 407 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 408 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 409 * </intent-filter></pre> 410 * <p>The secondary use of this activity is to insert a new note entry into 411 * an existing directory of notes. This is used when the user creates a new 412 * note: the INSERT action is executed on the directory of notes, causing 413 * this activity to run and have the user create the new note data which 414 * it then adds to the content provider.</p> 415 * </ol> 416 * 417 * <p>Given these capabilities, the following intents will resolve to the 418 * NoteEditor activity:</p> 419 * 420 * <ul> 421 * <li> <p><b>{ action=android.intent.action.VIEW 422 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 423 * shows the user the content of note <var>{ID}</var>.</p> 424 * <li> <p><b>{ action=android.app.action.EDIT 425 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 426 * allows the user to edit the content of note <var>{ID}</var>.</p> 427 * <li> <p><b>{ action=android.app.action.INSERT 428 * data=content://com.google.provider.NotePad/notes }</b> 429 * creates a new, empty note in the notes list at 430 * "content://com.google.provider.NotePad/notes" 431 * and allows the user to edit it. If they keep their changes, the URI 432 * of the newly created note is returned to the caller.</p> 433 * </ul> 434 * 435 * <p>The last activity, 436 * <code>com.android.notepad.TitleEditor</code>, allows the user to 437 * edit the title of a note. This could be implemented as a class that the 438 * application directly invokes (by explicitly setting its component in 439 * the Intent), but here we show a way you can publish alternative 440 * operations on existing data:</p> 441 * 442 * <pre> 443 * <intent-filter android:label="@string/resolve_title"> 444 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 445 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 446 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 447 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 448 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 449 * </intent-filter></pre> 450 * 451 * <p>In the single intent template here, we 452 * have created our own private action called 453 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 454 * edit the title of a note. It must be invoked on a specific note 455 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 456 * view and edit actions, but here displays and edits the title contained 457 * in the note data. 458 * 459 * <p>In addition to supporting the default category as usual, our title editor 460 * also supports two other standard categories: ALTERNATIVE and 461 * SELECTED_ALTERNATIVE.
