It 52 * can be used with {@link Context#startActivity(Intent) startActivity} to 53 * launch an {@link android.app.Activity}, 54 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 55 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 56 * and {@link android.content.Context#startService} or 57 * {@link android.content.Context#bindService} to communicate with a 58 * background {@link android.app.Service}. 59 * 60 * <p>An Intent provides a facility for performing late runtime binding between the code in 61 * different applications. Its most significant use is in the launching of activities, where it 62 * can be thought of as the glue between activities. It is basically a passive data structure 63 * holding an abstract description of an action to be performed.</p> 64 * 65 * <div class="special reference"> 66 * <h3>Developer Guides</h3> 67 * <p>For information about how to create and resolve intents, read the 68 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 69 * developer guide.</p> 70 * </div> 71 * 72 * <a name="IntentStructure"></a> 73 * <h3>Intent Structure</h3> 74 * <p>The primary pieces of information in an intent are:</p> 75 * 76 * <ul> 77 * <li> <p><b>action</b> -- The general action to be performed, such as 78 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 79 * etc.</p> 80 * </li> 81 * <li> <p><b>data</b> -- The data to operate on, such as a person record 82 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 83 * </li> 84 * </ul> 85 * 86 * 87 * <p>Some examples of action/data pairs are:</p> 88 * 89 * <ul> 90 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 91 * information about the person whose identifier is "1".</p> 92 * </li> 93 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 94 * the phone dialer with the person filled in.</p> 95 * </li> 96 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 97 * the phone dialer with the given number filled in. Note how the 98 * VIEW action does what what is considered the most reasonable thing for 99 * a particular URI.</p> 100 * </li> 101 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 102 * the phone dialer with the given number filled in.</p> 103 * </li> 104 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 105 * information about the person whose identifier is "1".</p> 106 * </li> 107 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 108 * a list of people, which the user can browse through. This example is a 109 * typical top-level entry into the Contacts application, showing you the 110 * list of people. Selecting a particular person to view would result in a 111 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 112 * being used to start an activity to display that person.</p> 113 * </li> 114 * </ul> 115 * 116 * <p>In addition to these primary attributes, there are a number of secondary 117 * attributes that you can also include with an intent:</p> 118 * 119 * <ul> 120 * <li> <p><b>category</b> -- Gives additional information about the action 121 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 122 * appear in the Launcher as a top-level application, while 123 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 124 * of alternative actions the user can perform on a piece of data.</p> 125 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 126 * intent data. Normally the type is inferred from the data itself. 127 * By setting this attribute, you disable that evaluation and force 128 * an explicit type.</p> 129 * <li> <p><b>component</b> -- Specifies an explicit name of a component 130 * class to use for the intent. Normally this is determined by looking 131 * at the other information in the intent (the action, data/type, and 132 * categories) and matching that with a component that can handle it. 133 * If this attribute is set then none of the evaluation is performed, 134 * and this component is used exactly as is. By specifying this attribute, 135 * all of the other Intent attributes become optional.</p> 136 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 137 * This can be used to provide extended information to the component. 138 * For example, if we have a action to send an e-mail message, we could 139 * also include extra pieces of data here to supply a subject, body, 140 * etc.</p> 141 * </ul> 142 * 143 * <p>Here are some examples of other operations you can specify as intents 144 * using these additional parameters:</p> 145 * 146 * <ul> 147 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 148 * Launch the home screen.</p> 149 * </li> 150 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 151 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 152 * vnd.android.cursor.item/phone}</i></b> 153 * -- Display the list of people's phone numbers, allowing the user to 154 * browse through them and pick one and return it to the parent activity.</p> 155 * </li> 156 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 157 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 158 * -- Display all pickers for data that can be opened with 159 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 160 * allowing the user to pick one of them and then some data inside of it 161 * and returning the resulting URI to the caller. This can be used, 162 * for example, in an e-mail application to allow the user to pick some 163 * data to include as an attachment.</p> 164 * </li> 165 * </ul> 166 * 167 * <p>There are a variety of standard Intent action and category constants 168 * defined in the Intent class, but applications can also define their own. 169 * These strings use java style scoping, to ensure they are unique -- for 170 * example, the standard {@link #ACTION_VIEW} is called 171 * "android.intent.action.VIEW".</p> 172 * 173 * <p>Put together, the set of actions, data types, categories, and extra data 174 * defines a language for the system allowing for the expression of phrases 175 * such as "call john smith's cell". As applications are added to the system, 176 * they can extend this language by adding new actions, types, and categories, or 177 * they can modify the behavior of existing phrases by supplying their own 178 * activities that handle them.</p> 179 * 180 * <a name="IntentResolution"></a> 181 * <h3>Intent Resolution</h3> 182 * 183 * <p>There are two primary forms of intents you will use. 184 * 185 * <ul> 186 * <li> <p><b>Explicit Intents</b> have specified a component (via 187 * {@link #setComponent} or {@link #setClass}), which provides the exact 188 * class to be run. Often these will not include any other information, 189 * simply being a way for an application to launch various internal 190 * activities it has as the user interacts with the application. 191 * 192 * <li> <p><b>Implicit Intents</b> have not specified a component; 193 * instead, they must include enough information for the system to 194 * determine which of the available components is best to run for that 195 * intent. 196 * </ul> 197 * 198 * <p>When using implicit intents, given such an arbitrary intent we need to 199 * know what to do with it. This is handled by the process of <em>Intent 200 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 201 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 202 * more activities/receivers) that can handle it.</p> 203 * 204 * <p>The intent resolution mechanism basically revolves around matching an 205 * Intent against all of the <intent-filter> descriptions in the 206 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 207 * objects explicitly registered with {@link Context#registerReceiver}.) More 208 * details on this can be found in the documentation on the {@link 209 * IntentFilter} class.</p> 210 * 211 * <p>There are three pieces of information in the Intent that are used for 212 * resolution: the action, type, and category. Using this information, a query 213 * is done on the {@link PackageManager} for a component that can handle the 214 * intent. The appropriate component is determined based on the intent 215 * information supplied in the <code>AndroidManifest.xml</code> file as 216 * follows:</p> 217 * 218 * <ul> 219 * <li> <p>The <b>action</b>, if given, must be listed by the component as 220 * one it handles.</p> 221 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 222 * already supplied in the Intent. Like the action, if a type is 223 * included in the intent (either explicitly or implicitly in its 224 * data), then this must be listed by the component as one it handles.</p> 225 * <li> For data that is not a <code>content:</code> URI and where no explicit 226 * type is included in the Intent, instead the <b>scheme</b> of the 227 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 228 * considered. Again like the action, if we are matching a scheme it 229 * must be listed by the component as one it can handle. 230 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 231 * by the activity as categories it handles. That is, if you include 232 * the categories {@link #CATEGORY_LAUNCHER} and 233 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 234 * with an intent that lists <em>both</em> of those categories. 235 * Activities will very often need to support the 236 * {@link #CATEGORY_DEFAULT} so that they can be found by 237 * {@link Context#startActivity Context.startActivity()}.</p> 238 * </ul> 239 * 240 * <p>For example, consider the Note Pad sample application that 241 * allows user to browse through a list of notes data and view details about 242 * individual items. Text in italics indicate places were you would replace a 243 * name with one specific to your own package.</p> 244 * 245 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 246 * package="<i>com.android.notepad</i>"> 247 * <application android:icon="@drawable/app_notes" 248 * android:label="@string/app_name"> 249 * 250 * <provider class=".NotePadProvider" 251 * android:authorities="<i>com.google.provider.NotePad</i>" /> 252 * 253 * <activity class=".NotesList" android:label="@string/title_notes_list"> 254 * <intent-filter> 255 * <action android:name="android.intent.action.MAIN" /> 256 * <category android:name="android.intent.category.LAUNCHER" /> 257 * </intent-filter> 258 * <intent-filter> 259 * <action android:name="android.intent.action.VIEW" /> 260 * <action android:name="android.intent.action.EDIT" /> 261 * <action android:name="android.intent.action.PICK" /> 262 * <category android:name="android.intent.category.DEFAULT" /> 263 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 264 * </intent-filter> 265 * <intent-filter> 266 * <action android:name="android.intent.action.GET_CONTENT" /> 267 * <category android:name="android.intent.category.DEFAULT" /> 268 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 269 * </intent-filter> 270 * </activity> 271 * 272 * <activity class=".NoteEditor" android:label="@string/title_note"> 273 * <intent-filter android:label="@string/resolve_edit"> 274 * <action android:name="android.intent.action.VIEW" /> 275 * <action android:name="android.intent.action.EDIT" /> 276 * <category android:name="android.intent.category.DEFAULT" /> 277 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 278 * </intent-filter> 279 * 280 * <intent-filter> 281 * <action android:name="android.intent.action.INSERT" /> 282 * <category android:name="android.intent.category.DEFAULT" /> 283 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 284 * </intent-filter> 285 * 286 * </activity> 287 * 288 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 289 * android:theme="@android:style/Theme.Dialog"> 290 * <intent-filter android:label="@string/resolve_title"> 291 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 292 * <category android:name="android.intent.category.DEFAULT" /> 293 * <category android:name="android.intent.category.ALTERNATIVE" /> 294 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 295 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 296 * </intent-filter> 297 * </activity> 298 * 299 * </application> 300 * </manifest></pre> 301 * 302 * <p>The first activity, 303 * <code>com.android.notepad.NotesList</code>, serves as our main 304 * entry into the app. It can do three things as described by its three intent 305 * templates: 306 * <ol> 307 * <li><pre> 308 * <intent-filter> 309 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 310 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 311 * </intent-filter></pre> 312 * <p>This provides a top-level entry into the NotePad application: the standard 313 * MAIN action is a main entry point (not requiring any other information in 314 * the Intent), and the LAUNCHER category says that this entry point should be 315 * listed in the application launcher.</p> 316 * <li><pre> 317 * <intent-filter> 318 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 319 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 320 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 321 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 322 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 323 * </intent-filter></pre> 324 * <p>This declares the things that the activity can do on a directory of 325 * notes. The type being supported is given with the <type> tag, where 326 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 327 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 328 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 329 * The activity allows the user to view or edit the directory of data (via 330 * the VIEW and EDIT actions), or to pick a particular note and return it 331 * to the caller (via the PICK action). Note also the DEFAULT category 332 * supplied here: this is <em>required</em> for the 333 * {@link Context#startActivity Context.startActivity} method to resolve your 334 * activity when its component name is not explicitly specified.</p> 335 * <li><pre> 336 * <intent-filter> 337 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 338 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 339 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 340 * </intent-filter></pre> 341 * <p>This filter describes the ability return to the caller a note selected by 342 * the user without needing to know where it came from. The data type 343 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 344 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 345 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 346 * The GET_CONTENT action is similar to the PICK action, where the activity 347 * will return to its caller a piece of data selected by the user. Here, 348 * however, the caller specifies the type of data they desire instead of 349 * the type of data the user will be picking from.</p> 350 * </ol> 351 * 352 * <p>Given these capabilities, the following intents will resolve to the 353 * NotesList activity:</p> 354 * 355 * <ul> 356 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 357 * activities that can be used as top-level entry points into an 358 * application.</p> 359 * <li> <p><b>{ action=android.app.action.MAIN, 360 * category=android.app.category.LAUNCHER }</b> is the actual intent 361 * used by the Launcher to populate its top-level list.</p> 362 * <li> <p><b>{ action=android.intent.action.VIEW 363 * data=content://com.google.provider.NotePad/notes }</b> 364 * displays a list of all the notes under 365 * "content://com.google.provider.NotePad/notes", which 366 * the user can browse through and see the details on.</p> 367 * <li> <p><b>{ action=android.app.action.PICK 368 * data=content://com.google.provider.NotePad/notes }</b> 369 * provides a list of the notes under 370 * "content://com.google.provider.NotePad/notes", from which 371 * the user can pick a note whose data URL is returned back to the caller.</p> 372 * <li> <p><b>{ action=android.app.action.GET_CONTENT 373 * type=vnd.android.cursor.item/vnd.google.note }</b> 374 * is similar to the pick action, but allows the caller to specify the 375 * kind of data they want back so that the system can find the appropriate 376 * activity to pick something of that data type.</p> 377 * </ul> 378 * 379 * <p>The second activity, 380 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 381 * note entry and allows them to edit it. It can do two things as described 382 * by its two intent templates: 383 * <ol> 384 * <li><pre> 385 * <intent-filter android:label="@string/resolve_edit"> 386 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 387 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 388 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 389 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 390 * </intent-filter></pre> 391 * <p>The first, primary, purpose of this activity is to let the user interact 392 * with a single note, as decribed by the MIME type 393 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 394 * either VIEW a note or allow the user to EDIT it. Again we support the 395 * DEFAULT category to allow the activity to be launched without explicitly 396 * specifying its component.</p> 397 * <li><pre> 398 * <intent-filter> 399 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 400 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 401 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 402 * </intent-filter></pre> 403 * <p>The secondary use of this activity is to insert a new note entry into 404 * an existing directory of notes. This is used when the user creates a new 405 * note: the INSERT action is executed on the directory of notes, causing 406 * this activity to run and have the user create the new note data which 407 * it then adds to the content provider.</p> 408 * </ol> 409 * 410 * <p>Given these capabilities, the following intents will resolve to the 411 * NoteEditor activity:</p> 412 * 413 * <ul> 414 * <li> <p><b>{ action=android.intent.action.VIEW 415 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 416 * shows the user the content of note <var>{ID}</var>.</p> 417 * <li> <p><b>{ action=android.app.action.EDIT 418 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 419 * allows the user to edit the content of note <var>{ID}</var>.</p> 420 * <li> <p><b>{ action=android.app.action.INSERT 421 * data=content://com.google.provider.NotePad/notes }</b> 422 * creates a new, empty note in the notes list at 423 * "content://com.google.provider.NotePad/notes" 424 * and allows the user to edit it. If they keep their changes, the URI 425 * of the newly created note is returned to the caller.</p> 426 * </ul> 427 * 428 * <p>The last activity, 429 * <code>com.android.notepad.TitleEditor</code>, allows the user to 430 * edit the title of a note. This could be implemented as a class that the 431 * application directly invokes (by explicitly setting its component in 432 * the Intent), but here we show a way you can publish alternative 433 * operations on existing data:</p> 434 * 435 * <pre> 436 * <intent-filter android:label="@string/resolve_title"> 437 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 438 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 439 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 440 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 441 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 442 * </intent-filter></pre> 443 * 444 * <p>In the single intent template here, we 445 * have created our own private action called 446 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 447 * edit the title of a note. It must be invoked on a specific note 448 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 449 * view and edit actions, but here displays and edits the title contained 450 * in the note data. 451 * 452 * <p>In addition to supporting the default category as usual, our title editor 453 * also supports two other standard categories: ALTERNATIVE and 454 * SELECTED_ALTERNATIVE.
