It 56 * can be used with {@link Context#startActivity(Intent) startActivity} to 57 * launch an {@link android.app.Activity}, 58 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 59 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 60 * and {@link android.content.Context#startService} or 61 * {@link android.content.Context#bindService} to communicate with a 62 * background {@link android.app.Service}. 63 * 64 * <p>An Intent provides a facility for performing late runtime binding between the code in 65 * different applications. Its most significant use is in the launching of activities, where it 66 * can be thought of as the glue between activities. It is basically a passive data structure 67 * holding an abstract description of an action to be performed.</p> 68 * 69 * <div class="special reference"> 70 * <h3>Developer Guides</h3> 71 * <p>For information about how to create and resolve intents, read the 72 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 73 * developer guide.</p> 74 * </div> 75 * 76 * <a name="IntentStructure"></a> 77 * <h3>Intent Structure</h3> 78 * <p>The primary pieces of information in an intent are:</p> 79 * 80 * <ul> 81 * <li> <p><b>action</b> -- The general action to be performed, such as 82 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 83 * etc.</p> 84 * </li> 85 * <li> <p><b>data</b> -- The data to operate on, such as a person record 86 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 87 * </li> 88 * </ul> 89 * 90 * 91 * <p>Some examples of action/data pairs are:</p> 92 * 93 * <ul> 94 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 95 * information about the person whose identifier is "1".</p> 96 * </li> 97 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 98 * the phone dialer with the person filled in.</p> 99 * </li> 100 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 101 * the phone dialer with the given number filled in. Note how the 102 * VIEW action does what what is considered the most reasonable thing for 103 * a particular URI.</p> 104 * </li> 105 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 106 * the phone dialer with the given number filled in.</p> 107 * </li> 108 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 109 * information about the person whose identifier is "1".</p> 110 * </li> 111 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 112 * a list of people, which the user can browse through. This example is a 113 * typical top-level entry into the Contacts application, showing you the 114 * list of people. Selecting a particular person to view would result in a 115 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 116 * being used to start an activity to display that person.</p> 117 * </li> 118 * </ul> 119 * 120 * <p>In addition to these primary attributes, there are a number of secondary 121 * attributes that you can also include with an intent:</p> 122 * 123 * <ul> 124 * <li> <p><b>category</b> -- Gives additional information about the action 125 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 126 * appear in the Launcher as a top-level application, while 127 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 128 * of alternative actions the user can perform on a piece of data.</p> 129 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 130 * intent data. Normally the type is inferred from the data itself. 131 * By setting this attribute, you disable that evaluation and force 132 * an explicit type.</p> 133 * <li> <p><b>component</b> -- Specifies an explicit name of a component 134 * class to use for the intent. Normally this is determined by looking 135 * at the other information in the intent (the action, data/type, and 136 * categories) and matching that with a component that can handle it. 137 * If this attribute is set then none of the evaluation is performed, 138 * and this component is used exactly as is. By specifying this attribute, 139 * all of the other Intent attributes become optional.</p> 140 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 141 * This can be used to provide extended information to the component. 142 * For example, if we have a action to send an e-mail message, we could 143 * also include extra pieces of data here to supply a subject, body, 144 * etc.</p> 145 * </ul> 146 * 147 * <p>Here are some examples of other operations you can specify as intents 148 * using these additional parameters:</p> 149 * 150 * <ul> 151 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 152 * Launch the home screen.</p> 153 * </li> 154 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 155 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 156 * vnd.android.cursor.item/phone}</i></b> 157 * -- Display the list of people's phone numbers, allowing the user to 158 * browse through them and pick one and return it to the parent activity.</p> 159 * </li> 160 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 161 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 162 * -- Display all pickers for data that can be opened with 163 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 164 * allowing the user to pick one of them and then some data inside of it 165 * and returning the resulting URI to the caller. This can be used, 166 * for example, in an e-mail application to allow the user to pick some 167 * data to include as an attachment.</p> 168 * </li> 169 * </ul> 170 * 171 * <p>There are a variety of standard Intent action and category constants 172 * defined in the Intent class, but applications can also define their own. 173 * These strings use java style scoping, to ensure they are unique -- for 174 * example, the standard {@link #ACTION_VIEW} is called 175 * "android.intent.action.VIEW".</p> 176 * 177 * <p>Put together, the set of actions, data types, categories, and extra data 178 * defines a language for the system allowing for the expression of phrases 179 * such as "call john smith's cell". As applications are added to the system, 180 * they can extend this language by adding new actions, types, and categories, or 181 * they can modify the behavior of existing phrases by supplying their own 182 * activities that handle them.</p> 183 * 184 * <a name="IntentResolution"></a> 185 * <h3>Intent Resolution</h3> 186 * 187 * <p>There are two primary forms of intents you will use. 188 * 189 * <ul> 190 * <li> <p><b>Explicit Intents</b> have specified a component (via 191 * {@link #setComponent} or {@link #setClass}), which provides the exact 192 * class to be run. Often these will not include any other information, 193 * simply being a way for an application to launch various internal 194 * activities it has as the user interacts with the application. 195 * 196 * <li> <p><b>Implicit Intents</b> have not specified a component; 197 * instead, they must include enough information for the system to 198 * determine which of the available components is best to run for that 199 * intent. 200 * </ul> 201 * 202 * <p>When using implicit intents, given such an arbitrary intent we need to 203 * know what to do with it. This is handled by the process of <em>Intent 204 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 205 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 206 * more activities/receivers) that can handle it.</p> 207 * 208 * <p>The intent resolution mechanism basically revolves around matching an 209 * Intent against all of the <intent-filter> descriptions in the 210 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 211 * objects explicitly registered with {@link Context#registerReceiver}.) More 212 * details on this can be found in the documentation on the {@link 213 * IntentFilter} class.</p> 214 * 215 * <p>There are three pieces of information in the Intent that are used for 216 * resolution: the action, type, and category. Using this information, a query 217 * is done on the {@link PackageManager} for a component that can handle the 218 * intent. The appropriate component is determined based on the intent 219 * information supplied in the <code>AndroidManifest.xml</code> file as 220 * follows:</p> 221 * 222 * <ul> 223 * <li> <p>The <b>action</b>, if given, must be listed by the component as 224 * one it handles.</p> 225 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 226 * already supplied in the Intent. Like the action, if a type is 227 * included in the intent (either explicitly or implicitly in its 228 * data), then this must be listed by the component as one it handles.</p> 229 * <li> For data that is not a <code>content:</code> URI and where no explicit 230 * type is included in the Intent, instead the <b>scheme</b> of the 231 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 232 * considered. Again like the action, if we are matching a scheme it 233 * must be listed by the component as one it can handle. 234 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 235 * by the activity as categories it handles. That is, if you include 236 * the categories {@link #CATEGORY_LAUNCHER} and 237 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 238 * with an intent that lists <em>both</em> of those categories. 239 * Activities will very often need to support the 240 * {@link #CATEGORY_DEFAULT} so that they can be found by 241 * {@link Context#startActivity Context.startActivity()}.</p> 242 * </ul> 243 * 244 * <p>For example, consider the Note Pad sample application that 245 * allows user to browse through a list of notes data and view details about 246 * individual items. Text in italics indicate places were you would replace a 247 * name with one specific to your own package.</p> 248 * 249 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 250 * package="<i>com.android.notepad</i>"> 251 * <application android:icon="@drawable/app_notes" 252 * android:label="@string/app_name"> 253 * 254 * <provider class=".NotePadProvider" 255 * android:authorities="<i>com.google.provider.NotePad</i>" /> 256 * 257 * <activity class=".NotesList" android:label="@string/title_notes_list"> 258 * <intent-filter> 259 * <action android:name="android.intent.action.MAIN" /> 260 * <category android:name="android.intent.category.LAUNCHER" /> 261 * </intent-filter> 262 * <intent-filter> 263 * <action android:name="android.intent.action.VIEW" /> 264 * <action android:name="android.intent.action.EDIT" /> 265 * <action android:name="android.intent.action.PICK" /> 266 * <category android:name="android.intent.category.DEFAULT" /> 267 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 268 * </intent-filter> 269 * <intent-filter> 270 * <action android:name="android.intent.action.GET_CONTENT" /> 271 * <category android:name="android.intent.category.DEFAULT" /> 272 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 273 * </intent-filter> 274 * </activity> 275 * 276 * <activity class=".NoteEditor" android:label="@string/title_note"> 277 * <intent-filter android:label="@string/resolve_edit"> 278 * <action android:name="android.intent.action.VIEW" /> 279 * <action android:name="android.intent.action.EDIT" /> 280 * <category android:name="android.intent.category.DEFAULT" /> 281 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 282 * </intent-filter> 283 * 284 * <intent-filter> 285 * <action android:name="android.intent.action.INSERT" /> 286 * <category android:name="android.intent.category.DEFAULT" /> 287 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 288 * </intent-filter> 289 * 290 * </activity> 291 * 292 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 293 * android:theme="@android:style/Theme.Dialog"> 294 * <intent-filter android:label="@string/resolve_title"> 295 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 296 * <category android:name="android.intent.category.DEFAULT" /> 297 * <category android:name="android.intent.category.ALTERNATIVE" /> 298 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 299 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 300 * </intent-filter> 301 * </activity> 302 * 303 * </application> 304 * </manifest></pre> 305 * 306 * <p>The first activity, 307 * <code>com.android.notepad.NotesList</code>, serves as our main 308 * entry into the app. It can do three things as described by its three intent 309 * templates: 310 * <ol> 311 * <li><pre> 312 * <intent-filter> 313 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 314 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 315 * </intent-filter></pre> 316 * <p>This provides a top-level entry into the NotePad application: the standard 317 * MAIN action is a main entry point (not requiring any other information in 318 * the Intent), and the LAUNCHER category says that this entry point should be 319 * listed in the application launcher.</p> 320 * <li><pre> 321 * <intent-filter> 322 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 323 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 324 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 325 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 326 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 327 * </intent-filter></pre> 328 * <p>This declares the things that the activity can do on a directory of 329 * notes. The type being supported is given with the <type> tag, where 330 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 331 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 332 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 333 * The activity allows the user to view or edit the directory of data (via 334 * the VIEW and EDIT actions), or to pick a particular note and return it 335 * to the caller (via the PICK action). Note also the DEFAULT category 336 * supplied here: this is <em>required</em> for the 337 * {@link Context#startActivity Context.startActivity} method to resolve your 338 * activity when its component name is not explicitly specified.</p> 339 * <li><pre> 340 * <intent-filter> 341 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 342 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 343 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 344 * </intent-filter></pre> 345 * <p>This filter describes the ability return to the caller a note selected by 346 * the user without needing to know where it came from. The data type 347 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 348 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 349 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 350 * The GET_CONTENT action is similar to the PICK action, where the activity 351 * will return to its caller a piece of data selected by the user. Here, 352 * however, the caller specifies the type of data they desire instead of 353 * the type of data the user will be picking from.</p> 354 * </ol> 355 * 356 * <p>Given these capabilities, the following intents will resolve to the 357 * NotesList activity:</p> 358 * 359 * <ul> 360 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 361 * activities that can be used as top-level entry points into an 362 * application.</p> 363 * <li> <p><b>{ action=android.app.action.MAIN, 364 * category=android.app.category.LAUNCHER }</b> is the actual intent 365 * used by the Launcher to populate its top-level list.</p> 366 * <li> <p><b>{ action=android.intent.action.VIEW 367 * data=content://com.google.provider.NotePad/notes }</b> 368 * displays a list of all the notes under 369 * "content://com.google.provider.NotePad/notes", which 370 * the user can browse through and see the details on.</p> 371 * <li> <p><b>{ action=android.app.action.PICK 372 * data=content://com.google.provider.NotePad/notes }</b> 373 * provides a list of the notes under 374 * "content://com.google.provider.NotePad/notes", from which 375 * the user can pick a note whose data URL is returned back to the caller.</p> 376 * <li> <p><b>{ action=android.app.action.GET_CONTENT 377 * type=vnd.android.cursor.item/vnd.google.note }</b> 378 * is similar to the pick action, but allows the caller to specify the 379 * kind of data they want back so that the system can find the appropriate 380 * activity to pick something of that data type.</p> 381 * </ul> 382 * 383 * <p>The second activity, 384 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 385 * note entry and allows them to edit it. It can do two things as described 386 * by its two intent templates: 387 * <ol> 388 * <li><pre> 389 * <intent-filter android:label="@string/resolve_edit"> 390 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 391 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 392 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 393 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 394 * </intent-filter></pre> 395 * <p>The first, primary, purpose of this activity is to let the user interact 396 * with a single note, as decribed by the MIME type 397 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 398 * either VIEW a note or allow the user to EDIT it. Again we support the 399 * DEFAULT category to allow the activity to be launched without explicitly 400 * specifying its component.</p> 401 * <li><pre> 402 * <intent-filter> 403 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 404 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 405 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 406 * </intent-filter></pre> 407 * <p>The secondary use of this activity is to insert a new note entry into 408 * an existing directory of notes. This is used when the user creates a new 409 * note: the INSERT action is executed on the directory of notes, causing 410 * this activity to run and have the user create the new note data which 411 * it then adds to the content provider.</p> 412 * </ol> 413 * 414 * <p>Given these capabilities, the following intents will resolve to the 415 * NoteEditor activity:</p> 416 * 417 * <ul> 418 * <li> <p><b>{ action=android.intent.action.VIEW 419 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 420 * shows the user the content of note <var>{ID}</var>.</p> 421 * <li> <p><b>{ action=android.app.action.EDIT 422 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 423 * allows the user to edit the content of note <var>{ID}</var>.</p> 424 * <li> <p><b>{ action=android.app.action.INSERT 425 * data=content://com.google.provider.NotePad/notes }</b> 426 * creates a new, empty note in the notes list at 427 * "content://com.google.provider.NotePad/notes" 428 * and allows the user to edit it. If they keep their changes, the URI 429 * of the newly created note is returned to the caller.</p> 430 * </ul> 431 * 432 * <p>The last activity, 433 * <code>com.android.notepad.TitleEditor</code>, allows the user to 434 * edit the title of a note. This could be implemented as a class that the 435 * application directly invokes (by explicitly setting its component in 436 * the Intent), but here we show a way you can publish alternative 437 * operations on existing data:</p> 438 * 439 * <pre> 440 * <intent-filter android:label="@string/resolve_title"> 441 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 442 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 443 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 444 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 445 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 446 * </intent-filter></pre> 447 * 448 * <p>In the single intent template here, we 449 * have created our own private action called 450 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 451 * edit the title of a note. It must be invoked on a specific note 452 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 453 * view and edit actions, but here displays and edits the title contained 454 * in the note data. 455 * 456 * <p>In addition to supporting the default category as usual, our title editor 457 * also supports two other standard categories: ALTERNATIVE and 458 * SELECTED_ALTERNATIVE.
