It 54 * can be used with {@link Context#startActivity(Intent) startActivity} to 55 * launch an {@link android.app.Activity}, 56 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 57 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 58 * and {@link android.content.Context#startService} or 59 * {@link android.content.Context#bindService} to communicate with a 60 * background {@link android.app.Service}. 61 * 62 * <p>An Intent provides a facility for performing late runtime binding between the code in 63 * different applications. Its most significant use is in the launching of activities, where it 64 * can be thought of as the glue between activities. It is basically a passive data structure 65 * holding an abstract description of an action to be performed.</p> 66 * 67 * <div class="special reference"> 68 * <h3>Developer Guides</h3> 69 * <p>For information about how to create and resolve intents, read the 70 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 71 * developer guide.</p> 72 * </div> 73 * 74 * <a name="IntentStructure"></a> 75 * <h3>Intent Structure</h3> 76 * <p>The primary pieces of information in an intent are:</p> 77 * 78 * <ul> 79 * <li> <p><b>action</b> -- The general action to be performed, such as 80 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 81 * etc.</p> 82 * </li> 83 * <li> <p><b>data</b> -- The data to operate on, such as a person record 84 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 85 * </li> 86 * </ul> 87 * 88 * 89 * <p>Some examples of action/data pairs are:</p> 90 * 91 * <ul> 92 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 93 * information about the person whose identifier is "1".</p> 94 * </li> 95 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 96 * the phone dialer with the person filled in.</p> 97 * </li> 98 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 99 * the phone dialer with the given number filled in. Note how the 100 * VIEW action does what what is considered the most reasonable thing for 101 * a particular URI.</p> 102 * </li> 103 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 104 * the phone dialer with the given number filled in.</p> 105 * </li> 106 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 107 * information about the person whose identifier is "1".</p> 108 * </li> 109 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 110 * a list of people, which the user can browse through. This example is a 111 * typical top-level entry into the Contacts application, showing you the 112 * list of people. Selecting a particular person to view would result in a 113 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 114 * being used to start an activity to display that person.</p> 115 * </li> 116 * </ul> 117 * 118 * <p>In addition to these primary attributes, there are a number of secondary 119 * attributes that you can also include with an intent:</p> 120 * 121 * <ul> 122 * <li> <p><b>category</b> -- Gives additional information about the action 123 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 124 * appear in the Launcher as a top-level application, while 125 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 126 * of alternative actions the user can perform on a piece of data.</p> 127 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 128 * intent data. Normally the type is inferred from the data itself. 129 * By setting this attribute, you disable that evaluation and force 130 * an explicit type.</p> 131 * <li> <p><b>component</b> -- Specifies an explicit name of a component 132 * class to use for the intent. Normally this is determined by looking 133 * at the other information in the intent (the action, data/type, and 134 * categories) and matching that with a component that can handle it. 135 * If this attribute is set then none of the evaluation is performed, 136 * and this component is used exactly as is. By specifying this attribute, 137 * all of the other Intent attributes become optional.</p> 138 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 139 * This can be used to provide extended information to the component. 140 * For example, if we have a action to send an e-mail message, we could 141 * also include extra pieces of data here to supply a subject, body, 142 * etc.</p> 143 * </ul> 144 * 145 * <p>Here are some examples of other operations you can specify as intents 146 * using these additional parameters:</p> 147 * 148 * <ul> 149 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 150 * Launch the home screen.</p> 151 * </li> 152 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 153 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 154 * vnd.android.cursor.item/phone}</i></b> 155 * -- Display the list of people's phone numbers, allowing the user to 156 * browse through them and pick one and return it to the parent activity.</p> 157 * </li> 158 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 159 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 160 * -- Display all pickers for data that can be opened with 161 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 162 * allowing the user to pick one of them and then some data inside of it 163 * and returning the resulting URI to the caller. This can be used, 164 * for example, in an e-mail application to allow the user to pick some 165 * data to include as an attachment.</p> 166 * </li> 167 * </ul> 168 * 169 * <p>There are a variety of standard Intent action and category constants 170 * defined in the Intent class, but applications can also define their own. 171 * These strings use java style scoping, to ensure they are unique -- for 172 * example, the standard {@link #ACTION_VIEW} is called 173 * "android.intent.action.VIEW".</p> 174 * 175 * <p>Put together, the set of actions, data types, categories, and extra data 176 * defines a language for the system allowing for the expression of phrases 177 * such as "call john smith's cell". As applications are added to the system, 178 * they can extend this language by adding new actions, types, and categories, or 179 * they can modify the behavior of existing phrases by supplying their own 180 * activities that handle them.</p> 181 * 182 * <a name="IntentResolution"></a> 183 * <h3>Intent Resolution</h3> 184 * 185 * <p>There are two primary forms of intents you will use. 186 * 187 * <ul> 188 * <li> <p><b>Explicit Intents</b> have specified a component (via 189 * {@link #setComponent} or {@link #setClass}), which provides the exact 190 * class to be run. Often these will not include any other information, 191 * simply being a way for an application to launch various internal 192 * activities it has as the user interacts with the application. 193 * 194 * <li> <p><b>Implicit Intents</b> have not specified a component; 195 * instead, they must include enough information for the system to 196 * determine which of the available components is best to run for that 197 * intent. 198 * </ul> 199 * 200 * <p>When using implicit intents, given such an arbitrary intent we need to 201 * know what to do with it. This is handled by the process of <em>Intent 202 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 203 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 204 * more activities/receivers) that can handle it.</p> 205 * 206 * <p>The intent resolution mechanism basically revolves around matching an 207 * Intent against all of the <intent-filter> descriptions in the 208 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 209 * objects explicitly registered with {@link Context#registerReceiver}.) More 210 * details on this can be found in the documentation on the {@link 211 * IntentFilter} class.</p> 212 * 213 * <p>There are three pieces of information in the Intent that are used for 214 * resolution: the action, type, and category. Using this information, a query 215 * is done on the {@link PackageManager} for a component that can handle the 216 * intent. The appropriate component is determined based on the intent 217 * information supplied in the <code>AndroidManifest.xml</code> file as 218 * follows:</p> 219 * 220 * <ul> 221 * <li> <p>The <b>action</b>, if given, must be listed by the component as 222 * one it handles.</p> 223 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 224 * already supplied in the Intent. Like the action, if a type is 225 * included in the intent (either explicitly or implicitly in its 226 * data), then this must be listed by the component as one it handles.</p> 227 * <li> For data that is not a <code>content:</code> URI and where no explicit 228 * type is included in the Intent, instead the <b>scheme</b> of the 229 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 230 * considered. Again like the action, if we are matching a scheme it 231 * must be listed by the component as one it can handle. 232 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 233 * by the activity as categories it handles. That is, if you include 234 * the categories {@link #CATEGORY_LAUNCHER} and 235 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 236 * with an intent that lists <em>both</em> of those categories. 237 * Activities will very often need to support the 238 * {@link #CATEGORY_DEFAULT} so that they can be found by 239 * {@link Context#startActivity Context.startActivity()}.</p> 240 * </ul> 241 * 242 * <p>For example, consider the Note Pad sample application that 243 * allows user to browse through a list of notes data and view details about 244 * individual items. Text in italics indicate places were you would replace a 245 * name with one specific to your own package.</p> 246 * 247 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 248 * package="<i>com.android.notepad</i>"> 249 * <application android:icon="@drawable/app_notes" 250 * android:label="@string/app_name"> 251 * 252 * <provider class=".NotePadProvider" 253 * android:authorities="<i>com.google.provider.NotePad</i>" /> 254 * 255 * <activity class=".NotesList" android:label="@string/title_notes_list"> 256 * <intent-filter> 257 * <action android:name="android.intent.action.MAIN" /> 258 * <category android:name="android.intent.category.LAUNCHER" /> 259 * </intent-filter> 260 * <intent-filter> 261 * <action android:name="android.intent.action.VIEW" /> 262 * <action android:name="android.intent.action.EDIT" /> 263 * <action android:name="android.intent.action.PICK" /> 264 * <category android:name="android.intent.category.DEFAULT" /> 265 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 266 * </intent-filter> 267 * <intent-filter> 268 * <action android:name="android.intent.action.GET_CONTENT" /> 269 * <category android:name="android.intent.category.DEFAULT" /> 270 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 271 * </intent-filter> 272 * </activity> 273 * 274 * <activity class=".NoteEditor" android:label="@string/title_note"> 275 * <intent-filter android:label="@string/resolve_edit"> 276 * <action android:name="android.intent.action.VIEW" /> 277 * <action android:name="android.intent.action.EDIT" /> 278 * <category android:name="android.intent.category.DEFAULT" /> 279 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 280 * </intent-filter> 281 * 282 * <intent-filter> 283 * <action android:name="android.intent.action.INSERT" /> 284 * <category android:name="android.intent.category.DEFAULT" /> 285 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 286 * </intent-filter> 287 * 288 * </activity> 289 * 290 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 291 * android:theme="@android:style/Theme.Dialog"> 292 * <intent-filter android:label="@string/resolve_title"> 293 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 294 * <category android:name="android.intent.category.DEFAULT" /> 295 * <category android:name="android.intent.category.ALTERNATIVE" /> 296 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 297 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 298 * </intent-filter> 299 * </activity> 300 * 301 * </application> 302 * </manifest></pre> 303 * 304 * <p>The first activity, 305 * <code>com.android.notepad.NotesList</code>, serves as our main 306 * entry into the app. It can do three things as described by its three intent 307 * templates: 308 * <ol> 309 * <li><pre> 310 * <intent-filter> 311 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 312 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 313 * </intent-filter></pre> 314 * <p>This provides a top-level entry into the NotePad application: the standard 315 * MAIN action is a main entry point (not requiring any other information in 316 * the Intent), and the LAUNCHER category says that this entry point should be 317 * listed in the application launcher.</p> 318 * <li><pre> 319 * <intent-filter> 320 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 321 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 322 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 323 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 324 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 325 * </intent-filter></pre> 326 * <p>This declares the things that the activity can do on a directory of 327 * notes. The type being supported is given with the <type> tag, where 328 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 329 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 330 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 331 * The activity allows the user to view or edit the directory of data (via 332 * the VIEW and EDIT actions), or to pick a particular note and return it 333 * to the caller (via the PICK action). Note also the DEFAULT category 334 * supplied here: this is <em>required</em> for the 335 * {@link Context#startActivity Context.startActivity} method to resolve your 336 * activity when its component name is not explicitly specified.</p> 337 * <li><pre> 338 * <intent-filter> 339 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 340 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 341 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 342 * </intent-filter></pre> 343 * <p>This filter describes the ability return to the caller a note selected by 344 * the user without needing to know where it came from. The data type 345 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 346 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 347 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 348 * The GET_CONTENT action is similar to the PICK action, where the activity 349 * will return to its caller a piece of data selected by the user. Here, 350 * however, the caller specifies the type of data they desire instead of 351 * the type of data the user will be picking from.</p> 352 * </ol> 353 * 354 * <p>Given these capabilities, the following intents will resolve to the 355 * NotesList activity:</p> 356 * 357 * <ul> 358 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 359 * activities that can be used as top-level entry points into an 360 * application.</p> 361 * <li> <p><b>{ action=android.app.action.MAIN, 362 * category=android.app.category.LAUNCHER }</b> is the actual intent 363 * used by the Launcher to populate its top-level list.</p> 364 * <li> <p><b>{ action=android.intent.action.VIEW 365 * data=content://com.google.provider.NotePad/notes }</b> 366 * displays a list of all the notes under 367 * "content://com.google.provider.NotePad/notes", which 368 * the user can browse through and see the details on.</p> 369 * <li> <p><b>{ action=android.app.action.PICK 370 * data=content://com.google.provider.NotePad/notes }</b> 371 * provides a list of the notes under 372 * "content://com.google.provider.NotePad/notes", from which 373 * the user can pick a note whose data URL is returned back to the caller.</p> 374 * <li> <p><b>{ action=android.app.action.GET_CONTENT 375 * type=vnd.android.cursor.item/vnd.google.note }</b> 376 * is similar to the pick action, but allows the caller to specify the 377 * kind of data they want back so that the system can find the appropriate 378 * activity to pick something of that data type.</p> 379 * </ul> 380 * 381 * <p>The second activity, 382 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 383 * note entry and allows them to edit it. It can do two things as described 384 * by its two intent templates: 385 * <ol> 386 * <li><pre> 387 * <intent-filter android:label="@string/resolve_edit"> 388 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 389 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 390 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 391 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 392 * </intent-filter></pre> 393 * <p>The first, primary, purpose of this activity is to let the user interact 394 * with a single note, as decribed by the MIME type 395 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 396 * either VIEW a note or allow the user to EDIT it. Again we support the 397 * DEFAULT category to allow the activity to be launched without explicitly 398 * specifying its component.</p> 399 * <li><pre> 400 * <intent-filter> 401 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 402 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 403 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 404 * </intent-filter></pre> 405 * <p>The secondary use of this activity is to insert a new note entry into 406 * an existing directory of notes. This is used when the user creates a new 407 * note: the INSERT action is executed on the directory of notes, causing 408 * this activity to run and have the user create the new note data which 409 * it then adds to the content provider.</p> 410 * </ol> 411 * 412 * <p>Given these capabilities, the following intents will resolve to the 413 * NoteEditor activity:</p> 414 * 415 * <ul> 416 * <li> <p><b>{ action=android.intent.action.VIEW 417 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 418 * shows the user the content of note <var>{ID}</var>.</p> 419 * <li> <p><b>{ action=android.app.action.EDIT 420 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 421 * allows the user to edit the content of note <var>{ID}</var>.</p> 422 * <li> <p><b>{ action=android.app.action.INSERT 423 * data=content://com.google.provider.NotePad/notes }</b> 424 * creates a new, empty note in the notes list at 425 * "content://com.google.provider.NotePad/notes" 426 * and allows the user to edit it. If they keep their changes, the URI 427 * of the newly created note is returned to the caller.</p> 428 * </ul> 429 * 430 * <p>The last activity, 431 * <code>com.android.notepad.TitleEditor</code>, allows the user to 432 * edit the title of a note. This could be implemented as a class that the 433 * application directly invokes (by explicitly setting its component in 434 * the Intent), but here we show a way you can publish alternative 435 * operations on existing data:</p> 436 * 437 * <pre> 438 * <intent-filter android:label="@string/resolve_title"> 439 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 440 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 441 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 442 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 443 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 444 * </intent-filter></pre> 445 * 446 * <p>In the single intent template here, we 447 * have created our own private action called 448 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 449 * edit the title of a note. It must be invoked on a specific note 450 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 451 * view and edit actions, but here displays and edits the title contained 452 * in the note data. 453 * 454 * <p>In addition to supporting the default category as usual, our title editor 455 * also supports two other standard categories: ALTERNATIVE and 456 * SELECTED_ALTERNATIVE.
