It 58 * can be used with {@link Context#startActivity(Intent) startActivity} to 59 * launch an {@link android.app.Activity}, 60 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 61 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 62 * and {@link android.content.Context#startService} or 63 * {@link android.content.Context#bindService} to communicate with a 64 * background {@link android.app.Service}. 65 * 66 * <p>An Intent provides a facility for performing late runtime binding between the code in 67 * different applications. Its most significant use is in the launching of activities, where it 68 * can be thought of as the glue between activities. It is basically a passive data structure 69 * holding an abstract description of an action to be performed.</p> 70 * 71 * <div class="special reference"> 72 * <h3>Developer Guides</h3> 73 * <p>For information about how to create and resolve intents, read the 74 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 75 * developer guide.</p> 76 * </div> 77 * 78 * <a name="IntentStructure"></a> 79 * <h3>Intent Structure</h3> 80 * <p>The primary pieces of information in an intent are:</p> 81 * 82 * <ul> 83 * <li> <p><b>action</b> -- The general action to be performed, such as 84 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 85 * etc.</p> 86 * </li> 87 * <li> <p><b>data</b> -- The data to operate on, such as a person record 88 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 89 * </li> 90 * </ul> 91 * 92 * 93 * <p>Some examples of action/data pairs are:</p> 94 * 95 * <ul> 96 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 97 * information about the person whose identifier is "1".</p> 98 * </li> 99 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 100 * the phone dialer with the person filled in.</p> 101 * </li> 102 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 103 * the phone dialer with the given number filled in. Note how the 104 * VIEW action does what what is considered the most reasonable thing for 105 * a particular URI.</p> 106 * </li> 107 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 108 * the phone dialer with the given number filled in.</p> 109 * </li> 110 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 111 * information about the person whose identifier is "1".</p> 112 * </li> 113 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 114 * a list of people, which the user can browse through. This example is a 115 * typical top-level entry into the Contacts application, showing you the 116 * list of people. Selecting a particular person to view would result in a 117 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 118 * being used to start an activity to display that person.</p> 119 * </li> 120 * </ul> 121 * 122 * <p>In addition to these primary attributes, there are a number of secondary 123 * attributes that you can also include with an intent:</p> 124 * 125 * <ul> 126 * <li> <p><b>category</b> -- Gives additional information about the action 127 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 128 * appear in the Launcher as a top-level application, while 129 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 130 * of alternative actions the user can perform on a piece of data.</p> 131 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 132 * intent data. Normally the type is inferred from the data itself. 133 * By setting this attribute, you disable that evaluation and force 134 * an explicit type.</p> 135 * <li> <p><b>component</b> -- Specifies an explicit name of a component 136 * class to use for the intent. Normally this is determined by looking 137 * at the other information in the intent (the action, data/type, and 138 * categories) and matching that with a component that can handle it. 139 * If this attribute is set then none of the evaluation is performed, 140 * and this component is used exactly as is. By specifying this attribute, 141 * all of the other Intent attributes become optional.</p> 142 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 143 * This can be used to provide extended information to the component. 144 * For example, if we have a action to send an e-mail message, we could 145 * also include extra pieces of data here to supply a subject, body, 146 * etc.</p> 147 * </ul> 148 * 149 * <p>Here are some examples of other operations you can specify as intents 150 * using these additional parameters:</p> 151 * 152 * <ul> 153 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 154 * Launch the home screen.</p> 155 * </li> 156 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 157 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 158 * vnd.android.cursor.item/phone}</i></b> 159 * -- Display the list of people's phone numbers, allowing the user to 160 * browse through them and pick one and return it to the parent activity.</p> 161 * </li> 162 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 163 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 164 * -- Display all pickers for data that can be opened with 165 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 166 * allowing the user to pick one of them and then some data inside of it 167 * and returning the resulting URI to the caller. This can be used, 168 * for example, in an e-mail application to allow the user to pick some 169 * data to include as an attachment.</p> 170 * </li> 171 * </ul> 172 * 173 * <p>There are a variety of standard Intent action and category constants 174 * defined in the Intent class, but applications can also define their own. 175 * These strings use java style scoping, to ensure they are unique -- for 176 * example, the standard {@link #ACTION_VIEW} is called 177 * "android.intent.action.VIEW".</p> 178 * 179 * <p>Put together, the set of actions, data types, categories, and extra data 180 * defines a language for the system allowing for the expression of phrases 181 * such as "call john smith's cell". As applications are added to the system, 182 * they can extend this language by adding new actions, types, and categories, or 183 * they can modify the behavior of existing phrases by supplying their own 184 * activities that handle them.</p> 185 * 186 * <a name="IntentResolution"></a> 187 * <h3>Intent Resolution</h3> 188 * 189 * <p>There are two primary forms of intents you will use. 190 * 191 * <ul> 192 * <li> <p><b>Explicit Intents</b> have specified a component (via 193 * {@link #setComponent} or {@link #setClass}), which provides the exact 194 * class to be run. Often these will not include any other information, 195 * simply being a way for an application to launch various internal 196 * activities it has as the user interacts with the application. 197 * 198 * <li> <p><b>Implicit Intents</b> have not specified a component; 199 * instead, they must include enough information for the system to 200 * determine which of the available components is best to run for that 201 * intent. 202 * </ul> 203 * 204 * <p>When using implicit intents, given such an arbitrary intent we need to 205 * know what to do with it. This is handled by the process of <em>Intent 206 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 207 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 208 * more activities/receivers) that can handle it.</p> 209 * 210 * <p>The intent resolution mechanism basically revolves around matching an 211 * Intent against all of the <intent-filter> descriptions in the 212 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 213 * objects explicitly registered with {@link Context#registerReceiver}.) More 214 * details on this can be found in the documentation on the {@link 215 * IntentFilter} class.</p> 216 * 217 * <p>There are three pieces of information in the Intent that are used for 218 * resolution: the action, type, and category. Using this information, a query 219 * is done on the {@link PackageManager} for a component that can handle the 220 * intent. The appropriate component is determined based on the intent 221 * information supplied in the <code>AndroidManifest.xml</code> file as 222 * follows:</p> 223 * 224 * <ul> 225 * <li> <p>The <b>action</b>, if given, must be listed by the component as 226 * one it handles.</p> 227 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 228 * already supplied in the Intent. Like the action, if a type is 229 * included in the intent (either explicitly or implicitly in its 230 * data), then this must be listed by the component as one it handles.</p> 231 * <li> For data that is not a <code>content:</code> URI and where no explicit 232 * type is included in the Intent, instead the <b>scheme</b> of the 233 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 234 * considered. Again like the action, if we are matching a scheme it 235 * must be listed by the component as one it can handle. 236 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 237 * by the activity as categories it handles. That is, if you include 238 * the categories {@link #CATEGORY_LAUNCHER} and 239 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 240 * with an intent that lists <em>both</em> of those categories. 241 * Activities will very often need to support the 242 * {@link #CATEGORY_DEFAULT} so that they can be found by 243 * {@link Context#startActivity Context.startActivity()}.</p> 244 * </ul> 245 * 246 * <p>For example, consider the Note Pad sample application that 247 * allows user to browse through a list of notes data and view details about 248 * individual items. Text in italics indicate places were you would replace a 249 * name with one specific to your own package.</p> 250 * 251 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 252 * package="<i>com.android.notepad</i>"> 253 * <application android:icon="@drawable/app_notes" 254 * android:label="@string/app_name"> 255 * 256 * <provider class=".NotePadProvider" 257 * android:authorities="<i>com.google.provider.NotePad</i>" /> 258 * 259 * <activity class=".NotesList" android:label="@string/title_notes_list"> 260 * <intent-filter> 261 * <action android:name="android.intent.action.MAIN" /> 262 * <category android:name="android.intent.category.LAUNCHER" /> 263 * </intent-filter> 264 * <intent-filter> 265 * <action android:name="android.intent.action.VIEW" /> 266 * <action android:name="android.intent.action.EDIT" /> 267 * <action android:name="android.intent.action.PICK" /> 268 * <category android:name="android.intent.category.DEFAULT" /> 269 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 270 * </intent-filter> 271 * <intent-filter> 272 * <action android:name="android.intent.action.GET_CONTENT" /> 273 * <category android:name="android.intent.category.DEFAULT" /> 274 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 275 * </intent-filter> 276 * </activity> 277 * 278 * <activity class=".NoteEditor" android:label="@string/title_note"> 279 * <intent-filter android:label="@string/resolve_edit"> 280 * <action android:name="android.intent.action.VIEW" /> 281 * <action android:name="android.intent.action.EDIT" /> 282 * <category android:name="android.intent.category.DEFAULT" /> 283 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 284 * </intent-filter> 285 * 286 * <intent-filter> 287 * <action android:name="android.intent.action.INSERT" /> 288 * <category android:name="android.intent.category.DEFAULT" /> 289 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 290 * </intent-filter> 291 * 292 * </activity> 293 * 294 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 295 * android:theme="@android:style/Theme.Dialog"> 296 * <intent-filter android:label="@string/resolve_title"> 297 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 298 * <category android:name="android.intent.category.DEFAULT" /> 299 * <category android:name="android.intent.category.ALTERNATIVE" /> 300 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 301 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 302 * </intent-filter> 303 * </activity> 304 * 305 * </application> 306 * </manifest></pre> 307 * 308 * <p>The first activity, 309 * <code>com.android.notepad.NotesList</code>, serves as our main 310 * entry into the app. It can do three things as described by its three intent 311 * templates: 312 * <ol> 313 * <li><pre> 314 * <intent-filter> 315 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 316 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 317 * </intent-filter></pre> 318 * <p>This provides a top-level entry into the NotePad application: the standard 319 * MAIN action is a main entry point (not requiring any other information in 320 * the Intent), and the LAUNCHER category says that this entry point should be 321 * listed in the application launcher.</p> 322 * <li><pre> 323 * <intent-filter> 324 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 325 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 326 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 327 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 328 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 329 * </intent-filter></pre> 330 * <p>This declares the things that the activity can do on a directory of 331 * notes. The type being supported is given with the <type> tag, where 332 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 333 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 334 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 335 * The activity allows the user to view or edit the directory of data (via 336 * the VIEW and EDIT actions), or to pick a particular note and return it 337 * to the caller (via the PICK action). Note also the DEFAULT category 338 * supplied here: this is <em>required</em> for the 339 * {@link Context#startActivity Context.startActivity} method to resolve your 340 * activity when its component name is not explicitly specified.</p> 341 * <li><pre> 342 * <intent-filter> 343 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 344 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 345 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 346 * </intent-filter></pre> 347 * <p>This filter describes the ability return to the caller a note selected by 348 * the user without needing to know where it came from. The data type 349 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 350 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 351 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 352 * The GET_CONTENT action is similar to the PICK action, where the activity 353 * will return to its caller a piece of data selected by the user. Here, 354 * however, the caller specifies the type of data they desire instead of 355 * the type of data the user will be picking from.</p> 356 * </ol> 357 * 358 * <p>Given these capabilities, the following intents will resolve to the 359 * NotesList activity:</p> 360 * 361 * <ul> 362 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 363 * activities that can be used as top-level entry points into an 364 * application.</p> 365 * <li> <p><b>{ action=android.app.action.MAIN, 366 * category=android.app.category.LAUNCHER }</b> is the actual intent 367 * used by the Launcher to populate its top-level list.</p> 368 * <li> <p><b>{ action=android.intent.action.VIEW 369 * data=content://com.google.provider.NotePad/notes }</b> 370 * displays a list of all the notes under 371 * "content://com.google.provider.NotePad/notes", which 372 * the user can browse through and see the details on.</p> 373 * <li> <p><b>{ action=android.app.action.PICK 374 * data=content://com.google.provider.NotePad/notes }</b> 375 * provides a list of the notes under 376 * "content://com.google.provider.NotePad/notes", from which 377 * the user can pick a note whose data URL is returned back to the caller.</p> 378 * <li> <p><b>{ action=android.app.action.GET_CONTENT 379 * type=vnd.android.cursor.item/vnd.google.note }</b> 380 * is similar to the pick action, but allows the caller to specify the 381 * kind of data they want back so that the system can find the appropriate 382 * activity to pick something of that data type.</p> 383 * </ul> 384 * 385 * <p>The second activity, 386 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 387 * note entry and allows them to edit it. It can do two things as described 388 * by its two intent templates: 389 * <ol> 390 * <li><pre> 391 * <intent-filter android:label="@string/resolve_edit"> 392 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 393 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 394 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 395 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 396 * </intent-filter></pre> 397 * <p>The first, primary, purpose of this activity is to let the user interact 398 * with a single note, as decribed by the MIME type 399 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 400 * either VIEW a note or allow the user to EDIT it. Again we support the 401 * DEFAULT category to allow the activity to be launched without explicitly 402 * specifying its component.</p> 403 * <li><pre> 404 * <intent-filter> 405 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 406 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 407 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 408 * </intent-filter></pre> 409 * <p>The secondary use of this activity is to insert a new note entry into 410 * an existing directory of notes. This is used when the user creates a new 411 * note: the INSERT action is executed on the directory of notes, causing 412 * this activity to run and have the user create the new note data which 413 * it then adds to the content provider.</p> 414 * </ol> 415 * 416 * <p>Given these capabilities, the following intents will resolve to the 417 * NoteEditor activity:</p> 418 * 419 * <ul> 420 * <li> <p><b>{ action=android.intent.action.VIEW 421 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 422 * shows the user the content of note <var>{ID}</var>.</p> 423 * <li> <p><b>{ action=android.app.action.EDIT 424 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 425 * allows the user to edit the content of note <var>{ID}</var>.</p> 426 * <li> <p><b>{ action=android.app.action.INSERT 427 * data=content://com.google.provider.NotePad/notes }</b> 428 * creates a new, empty note in the notes list at 429 * "content://com.google.provider.NotePad/notes" 430 * and allows the user to edit it. If they keep their changes, the URI 431 * of the newly created note is returned to the caller.</p> 432 * </ul> 433 * 434 * <p>The last activity, 435 * <code>com.android.notepad.TitleEditor</code>, allows the user to 436 * edit the title of a note. This could be implemented as a class that the 437 * application directly invokes (by explicitly setting its component in 438 * the Intent), but here we show a way you can publish alternative 439 * operations on existing data:</p> 440 * 441 * <pre> 442 * <intent-filter android:label="@string/resolve_title"> 443 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 444 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 445 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 446 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 447 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 448 * </intent-filter></pre> 449 * 450 * <p>In the single intent template here, we 451 * have created our own private action called 452 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 453 * edit the title of a note. It must be invoked on a specific note 454 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 455 * view and edit actions, but here displays and edits the title contained 456 * in the note data. 457 * 458 * <p>In addition to supporting the default category as usual, our title editor 459 * also supports two other standard categories: ALTERNATIVE and 460 * SELECTED_ALTERNATIVE.
