It 60 * can be used with {@link Context#startActivity(Intent) startActivity} to 61 * launch an {@link android.app.Activity}, 62 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 63 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 64 * and {@link android.content.Context#startService} or 65 * {@link android.content.Context#bindService} to communicate with a 66 * background {@link android.app.Service}. 67 * 68 * <p>An Intent provides a facility for performing late runtime binding between the code in 69 * different applications. Its most significant use is in the launching of activities, where it 70 * can be thought of as the glue between activities. It is basically a passive data structure 71 * holding an abstract description of an action to be performed.</p> 72 * 73 * <div class="special reference"> 74 * <h3>Developer Guides</h3> 75 * <p>For information about how to create and resolve intents, read the 76 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 77 * developer guide.</p> 78 * </div> 79 * 80 * <a name="IntentStructure"></a> 81 * <h3>Intent Structure</h3> 82 * <p>The primary pieces of information in an intent are:</p> 83 * 84 * <ul> 85 * <li> <p><b>action</b> -- The general action to be performed, such as 86 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 87 * etc.</p> 88 * </li> 89 * <li> <p><b>data</b> -- The data to operate on, such as a person record 90 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 91 * </li> 92 * </ul> 93 * 94 * 95 * <p>Some examples of action/data pairs are:</p> 96 * 97 * <ul> 98 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 99 * information about the person whose identifier is "1".</p> 100 * </li> 101 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 102 * the phone dialer with the person filled in.</p> 103 * </li> 104 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 105 * the phone dialer with the given number filled in. Note how the 106 * VIEW action does what what is considered the most reasonable thing for 107 * a particular URI.</p> 108 * </li> 109 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 110 * the phone dialer with the given number filled in.</p> 111 * </li> 112 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 113 * information about the person whose identifier is "1".</p> 114 * </li> 115 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 116 * a list of people, which the user can browse through. This example is a 117 * typical top-level entry into the Contacts application, showing you the 118 * list of people. Selecting a particular person to view would result in a 119 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 120 * being used to start an activity to display that person.</p> 121 * </li> 122 * </ul> 123 * 124 * <p>In addition to these primary attributes, there are a number of secondary 125 * attributes that you can also include with an intent:</p> 126 * 127 * <ul> 128 * <li> <p><b>category</b> -- Gives additional information about the action 129 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 130 * appear in the Launcher as a top-level application, while 131 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 132 * of alternative actions the user can perform on a piece of data.</p> 133 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 134 * intent data. Normally the type is inferred from the data itself. 135 * By setting this attribute, you disable that evaluation and force 136 * an explicit type.</p> 137 * <li> <p><b>component</b> -- Specifies an explicit name of a component 138 * class to use for the intent. Normally this is determined by looking 139 * at the other information in the intent (the action, data/type, and 140 * categories) and matching that with a component that can handle it. 141 * If this attribute is set then none of the evaluation is performed, 142 * and this component is used exactly as is. By specifying this attribute, 143 * all of the other Intent attributes become optional.</p> 144 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 145 * This can be used to provide extended information to the component. 146 * For example, if we have a action to send an e-mail message, we could 147 * also include extra pieces of data here to supply a subject, body, 148 * etc.</p> 149 * </ul> 150 * 151 * <p>Here are some examples of other operations you can specify as intents 152 * using these additional parameters:</p> 153 * 154 * <ul> 155 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 156 * Launch the home screen.</p> 157 * </li> 158 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 159 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 160 * vnd.android.cursor.item/phone}</i></b> 161 * -- Display the list of people's phone numbers, allowing the user to 162 * browse through them and pick one and return it to the parent activity.</p> 163 * </li> 164 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 165 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 166 * -- Display all pickers for data that can be opened with 167 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 168 * allowing the user to pick one of them and then some data inside of it 169 * and returning the resulting URI to the caller. This can be used, 170 * for example, in an e-mail application to allow the user to pick some 171 * data to include as an attachment.</p> 172 * </li> 173 * </ul> 174 * 175 * <p>There are a variety of standard Intent action and category constants 176 * defined in the Intent class, but applications can also define their own. 177 * These strings use java style scoping, to ensure they are unique -- for 178 * example, the standard {@link #ACTION_VIEW} is called 179 * "android.intent.action.VIEW".</p> 180 * 181 * <p>Put together, the set of actions, data types, categories, and extra data 182 * defines a language for the system allowing for the expression of phrases 183 * such as "call john smith's cell". As applications are added to the system, 184 * they can extend this language by adding new actions, types, and categories, or 185 * they can modify the behavior of existing phrases by supplying their own 186 * activities that handle them.</p> 187 * 188 * <a name="IntentResolution"></a> 189 * <h3>Intent Resolution</h3> 190 * 191 * <p>There are two primary forms of intents you will use. 192 * 193 * <ul> 194 * <li> <p><b>Explicit Intents</b> have specified a component (via 195 * {@link #setComponent} or {@link #setClass}), which provides the exact 196 * class to be run. Often these will not include any other information, 197 * simply being a way for an application to launch various internal 198 * activities it has as the user interacts with the application. 199 * 200 * <li> <p><b>Implicit Intents</b> have not specified a component; 201 * instead, they must include enough information for the system to 202 * determine which of the available components is best to run for that 203 * intent. 204 * </ul> 205 * 206 * <p>When using implicit intents, given such an arbitrary intent we need to 207 * know what to do with it. This is handled by the process of <em>Intent 208 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 209 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 210 * more activities/receivers) that can handle it.</p> 211 * 212 * <p>The intent resolution mechanism basically revolves around matching an 213 * Intent against all of the <intent-filter> descriptions in the 214 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 215 * objects explicitly registered with {@link Context#registerReceiver}.) More 216 * details on this can be found in the documentation on the {@link 217 * IntentFilter} class.</p> 218 * 219 * <p>There are three pieces of information in the Intent that are used for 220 * resolution: the action, type, and category. Using this information, a query 221 * is done on the {@link PackageManager} for a component that can handle the 222 * intent. The appropriate component is determined based on the intent 223 * information supplied in the <code>AndroidManifest.xml</code> file as 224 * follows:</p> 225 * 226 * <ul> 227 * <li> <p>The <b>action</b>, if given, must be listed by the component as 228 * one it handles.</p> 229 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 230 * already supplied in the Intent. Like the action, if a type is 231 * included in the intent (either explicitly or implicitly in its 232 * data), then this must be listed by the component as one it handles.</p> 233 * <li> For data that is not a <code>content:</code> URI and where no explicit 234 * type is included in the Intent, instead the <b>scheme</b> of the 235 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 236 * considered. Again like the action, if we are matching a scheme it 237 * must be listed by the component as one it can handle. 238 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 239 * by the activity as categories it handles. That is, if you include 240 * the categories {@link #CATEGORY_LAUNCHER} and 241 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 242 * with an intent that lists <em>both</em> of those categories. 243 * Activities will very often need to support the 244 * {@link #CATEGORY_DEFAULT} so that they can be found by 245 * {@link Context#startActivity Context.startActivity()}.</p> 246 * </ul> 247 * 248 * <p>For example, consider the Note Pad sample application that 249 * allows user to browse through a list of notes data and view details about 250 * individual items. Text in italics indicate places were you would replace a 251 * name with one specific to your own package.</p> 252 * 253 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 254 * package="<i>com.android.notepad</i>"> 255 * <application android:icon="@drawable/app_notes" 256 * android:label="@string/app_name"> 257 * 258 * <provider class=".NotePadProvider" 259 * android:authorities="<i>com.google.provider.NotePad</i>" /> 260 * 261 * <activity class=".NotesList" android:label="@string/title_notes_list"> 262 * <intent-filter> 263 * <action android:name="android.intent.action.MAIN" /> 264 * <category android:name="android.intent.category.LAUNCHER" /> 265 * </intent-filter> 266 * <intent-filter> 267 * <action android:name="android.intent.action.VIEW" /> 268 * <action android:name="android.intent.action.EDIT" /> 269 * <action android:name="android.intent.action.PICK" /> 270 * <category android:name="android.intent.category.DEFAULT" /> 271 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 272 * </intent-filter> 273 * <intent-filter> 274 * <action android:name="android.intent.action.GET_CONTENT" /> 275 * <category android:name="android.intent.category.DEFAULT" /> 276 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 277 * </intent-filter> 278 * </activity> 279 * 280 * <activity class=".NoteEditor" android:label="@string/title_note"> 281 * <intent-filter android:label="@string/resolve_edit"> 282 * <action android:name="android.intent.action.VIEW" /> 283 * <action android:name="android.intent.action.EDIT" /> 284 * <category android:name="android.intent.category.DEFAULT" /> 285 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 286 * </intent-filter> 287 * 288 * <intent-filter> 289 * <action android:name="android.intent.action.INSERT" /> 290 * <category android:name="android.intent.category.DEFAULT" /> 291 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 292 * </intent-filter> 293 * 294 * </activity> 295 * 296 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 297 * android:theme="@android:style/Theme.Dialog"> 298 * <intent-filter android:label="@string/resolve_title"> 299 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 300 * <category android:name="android.intent.category.DEFAULT" /> 301 * <category android:name="android.intent.category.ALTERNATIVE" /> 302 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 303 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 304 * </intent-filter> 305 * </activity> 306 * 307 * </application> 308 * </manifest></pre> 309 * 310 * <p>The first activity, 311 * <code>com.android.notepad.NotesList</code>, serves as our main 312 * entry into the app. It can do three things as described by its three intent 313 * templates: 314 * <ol> 315 * <li><pre> 316 * <intent-filter> 317 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 318 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 319 * </intent-filter></pre> 320 * <p>This provides a top-level entry into the NotePad application: the standard 321 * MAIN action is a main entry point (not requiring any other information in 322 * the Intent), and the LAUNCHER category says that this entry point should be 323 * listed in the application launcher.</p> 324 * <li><pre> 325 * <intent-filter> 326 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 327 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 328 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 329 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 330 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 331 * </intent-filter></pre> 332 * <p>This declares the things that the activity can do on a directory of 333 * notes. The type being supported is given with the <type> tag, where 334 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 335 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 336 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 337 * The activity allows the user to view or edit the directory of data (via 338 * the VIEW and EDIT actions), or to pick a particular note and return it 339 * to the caller (via the PICK action). Note also the DEFAULT category 340 * supplied here: this is <em>required</em> for the 341 * {@link Context#startActivity Context.startActivity} method to resolve your 342 * activity when its component name is not explicitly specified.</p> 343 * <li><pre> 344 * <intent-filter> 345 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 346 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 347 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 348 * </intent-filter></pre> 349 * <p>This filter describes the ability return to the caller a note selected by 350 * the user without needing to know where it came from. The data type 351 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 352 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 353 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 354 * The GET_CONTENT action is similar to the PICK action, where the activity 355 * will return to its caller a piece of data selected by the user. Here, 356 * however, the caller specifies the type of data they desire instead of 357 * the type of data the user will be picking from.</p> 358 * </ol> 359 * 360 * <p>Given these capabilities, the following intents will resolve to the 361 * NotesList activity:</p> 362 * 363 * <ul> 364 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 365 * activities that can be used as top-level entry points into an 366 * application.</p> 367 * <li> <p><b>{ action=android.app.action.MAIN, 368 * category=android.app.category.LAUNCHER }</b> is the actual intent 369 * used by the Launcher to populate its top-level list.</p> 370 * <li> <p><b>{ action=android.intent.action.VIEW 371 * data=content://com.google.provider.NotePad/notes }</b> 372 * displays a list of all the notes under 373 * "content://com.google.provider.NotePad/notes", which 374 * the user can browse through and see the details on.</p> 375 * <li> <p><b>{ action=android.app.action.PICK 376 * data=content://com.google.provider.NotePad/notes }</b> 377 * provides a list of the notes under 378 * "content://com.google.provider.NotePad/notes", from which 379 * the user can pick a note whose data URL is returned back to the caller.</p> 380 * <li> <p><b>{ action=android.app.action.GET_CONTENT 381 * type=vnd.android.cursor.item/vnd.google.note }</b> 382 * is similar to the pick action, but allows the caller to specify the 383 * kind of data they want back so that the system can find the appropriate 384 * activity to pick something of that data type.</p> 385 * </ul> 386 * 387 * <p>The second activity, 388 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 389 * note entry and allows them to edit it. It can do two things as described 390 * by its two intent templates: 391 * <ol> 392 * <li><pre> 393 * <intent-filter android:label="@string/resolve_edit"> 394 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 395 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 396 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 397 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 398 * </intent-filter></pre> 399 * <p>The first, primary, purpose of this activity is to let the user interact 400 * with a single note, as decribed by the MIME type 401 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 402 * either VIEW a note or allow the user to EDIT it. Again we support the 403 * DEFAULT category to allow the activity to be launched without explicitly 404 * specifying its component.</p> 405 * <li><pre> 406 * <intent-filter> 407 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 408 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 409 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 410 * </intent-filter></pre> 411 * <p>The secondary use of this activity is to insert a new note entry into 412 * an existing directory of notes. This is used when the user creates a new 413 * note: the INSERT action is executed on the directory of notes, causing 414 * this activity to run and have the user create the new note data which 415 * it then adds to the content provider.</p> 416 * </ol> 417 * 418 * <p>Given these capabilities, the following intents will resolve to the 419 * NoteEditor activity:</p> 420 * 421 * <ul> 422 * <li> <p><b>{ action=android.intent.action.VIEW 423 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 424 * shows the user the content of note <var>{ID}</var>.</p> 425 * <li> <p><b>{ action=android.app.action.EDIT 426 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 427 * allows the user to edit the content of note <var>{ID}</var>.</p> 428 * <li> <p><b>{ action=android.app.action.INSERT 429 * data=content://com.google.provider.NotePad/notes }</b> 430 * creates a new, empty note in the notes list at 431 * "content://com.google.provider.NotePad/notes" 432 * and allows the user to edit it. If they keep their changes, the URI 433 * of the newly created note is returned to the caller.</p> 434 * </ul> 435 * 436 * <p>The last activity, 437 * <code>com.android.notepad.TitleEditor</code>, allows the user to 438 * edit the title of a note. This could be implemented as a class that the 439 * application directly invokes (by explicitly setting its component in 440 * the Intent), but here we show a way you can publish alternative 441 * operations on existing data:</p> 442 * 443 * <pre> 444 * <intent-filter android:label="@string/resolve_title"> 445 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 446 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 447 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 448 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 449 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 450 * </intent-filter></pre> 451 * 452 * <p>In the single intent template here, we 453 * have created our own private action called 454 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 455 * edit the title of a note. It must be invoked on a specific note 456 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 457 * view and edit actions, but here displays and edits the title contained 458 * in the note data. 459 * 460 * <p>In addition to supporting the default category as usual, our title editor 461 * also supports two other standard categories: ALTERNATIVE and 462 * SELECTED_ALTERNATIVE.
