It 51 * can be used with {@link Context#startActivity(Intent) startActivity} to 52 * launch an {@link android.app.Activity}, 53 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 54 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 55 * and {@link android.content.Context#startService} or 56 * {@link android.content.Context#bindService} to communicate with a 57 * background {@link android.app.Service}. 58 * 59 * <p>An Intent provides a facility for performing late runtime binding between the code in 60 * different applications. Its most significant use is in the launching of activities, where it 61 * can be thought of as the glue between activities. It is basically a passive data structure 62 * holding an abstract description of an action to be performed.</p> 63 * 64 * <div class="special reference"> 65 * <h3>Developer Guides</h3> 66 * <p>For information about how to create and resolve intents, read the 67 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 68 * developer guide.</p> 69 * </div> 70 * 71 * <a name="IntentStructure"></a> 72 * <h3>Intent Structure</h3> 73 * <p>The primary pieces of information in an intent are:</p> 74 * 75 * <ul> 76 * <li> <p><b>action</b> -- The general action to be performed, such as 77 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 78 * etc.</p> 79 * </li> 80 * <li> <p><b>data</b> -- The data to operate on, such as a person record 81 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 82 * </li> 83 * </ul> 84 * 85 * 86 * <p>Some examples of action/data pairs are:</p> 87 * 88 * <ul> 89 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 90 * information about the person whose identifier is "1".</p> 91 * </li> 92 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 93 * the phone dialer with the person filled in.</p> 94 * </li> 95 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 96 * the phone dialer with the given number filled in. Note how the 97 * VIEW action does what what is considered the most reasonable thing for 98 * a particular URI.</p> 99 * </li> 100 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 101 * the phone dialer with the given number filled in.</p> 102 * </li> 103 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 104 * information about the person whose identifier is "1".</p> 105 * </li> 106 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 107 * a list of people, which the user can browse through. This example is a 108 * typical top-level entry into the Contacts application, showing you the 109 * list of people. Selecting a particular person to view would result in a 110 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 111 * being used to start an activity to display that person.</p> 112 * </li> 113 * </ul> 114 * 115 * <p>In addition to these primary attributes, there are a number of secondary 116 * attributes that you can also include with an intent:</p> 117 * 118 * <ul> 119 * <li> <p><b>category</b> -- Gives additional information about the action 120 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 121 * appear in the Launcher as a top-level application, while 122 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 123 * of alternative actions the user can perform on a piece of data.</p> 124 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 125 * intent data. Normally the type is inferred from the data itself. 126 * By setting this attribute, you disable that evaluation and force 127 * an explicit type.</p> 128 * <li> <p><b>component</b> -- Specifies an explicit name of a component 129 * class to use for the intent. Normally this is determined by looking 130 * at the other information in the intent (the action, data/type, and 131 * categories) and matching that with a component that can handle it. 132 * If this attribute is set then none of the evaluation is performed, 133 * and this component is used exactly as is. By specifying this attribute, 134 * all of the other Intent attributes become optional.</p> 135 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 136 * This can be used to provide extended information to the component. 137 * For example, if we have a action to send an e-mail message, we could 138 * also include extra pieces of data here to supply a subject, body, 139 * etc.</p> 140 * </ul> 141 * 142 * <p>Here are some examples of other operations you can specify as intents 143 * using these additional parameters:</p> 144 * 145 * <ul> 146 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 147 * Launch the home screen.</p> 148 * </li> 149 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 150 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 151 * vnd.android.cursor.item/phone}</i></b> 152 * -- Display the list of people's phone numbers, allowing the user to 153 * browse through them and pick one and return it to the parent activity.</p> 154 * </li> 155 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 156 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 157 * -- Display all pickers for data that can be opened with 158 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 159 * allowing the user to pick one of them and then some data inside of it 160 * and returning the resulting URI to the caller. This can be used, 161 * for example, in an e-mail application to allow the user to pick some 162 * data to include as an attachment.</p> 163 * </li> 164 * </ul> 165 * 166 * <p>There are a variety of standard Intent action and category constants 167 * defined in the Intent class, but applications can also define their own. 168 * These strings use java style scoping, to ensure they are unique -- for 169 * example, the standard {@link #ACTION_VIEW} is called 170 * "android.intent.action.VIEW".</p> 171 * 172 * <p>Put together, the set of actions, data types, categories, and extra data 173 * defines a language for the system allowing for the expression of phrases 174 * such as "call john smith's cell". As applications are added to the system, 175 * they can extend this language by adding new actions, types, and categories, or 176 * they can modify the behavior of existing phrases by supplying their own 177 * activities that handle them.</p> 178 * 179 * <a name="IntentResolution"></a> 180 * <h3>Intent Resolution</h3> 181 * 182 * <p>There are two primary forms of intents you will use. 183 * 184 * <ul> 185 * <li> <p><b>Explicit Intents</b> have specified a component (via 186 * {@link #setComponent} or {@link #setClass}), which provides the exact 187 * class to be run. Often these will not include any other information, 188 * simply being a way for an application to launch various internal 189 * activities it has as the user interacts with the application. 190 * 191 * <li> <p><b>Implicit Intents</b> have not specified a component; 192 * instead, they must include enough information for the system to 193 * determine which of the available components is best to run for that 194 * intent. 195 * </ul> 196 * 197 * <p>When using implicit intents, given such an arbitrary intent we need to 198 * know what to do with it. This is handled by the process of <em>Intent 199 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 200 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 201 * more activities/receivers) that can handle it.</p> 202 * 203 * <p>The intent resolution mechanism basically revolves around matching an 204 * Intent against all of the <intent-filter> descriptions in the 205 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 206 * objects explicitly registered with {@link Context#registerReceiver}.) More 207 * details on this can be found in the documentation on the {@link 208 * IntentFilter} class.</p> 209 * 210 * <p>There are three pieces of information in the Intent that are used for 211 * resolution: the action, type, and category. Using this information, a query 212 * is done on the {@link PackageManager} for a component that can handle the 213 * intent. The appropriate component is determined based on the intent 214 * information supplied in the <code>AndroidManifest.xml</code> file as 215 * follows:</p> 216 * 217 * <ul> 218 * <li> <p>The <b>action</b>, if given, must be listed by the component as 219 * one it handles.</p> 220 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 221 * already supplied in the Intent. Like the action, if a type is 222 * included in the intent (either explicitly or implicitly in its 223 * data), then this must be listed by the component as one it handles.</p> 224 * <li> For data that is not a <code>content:</code> URI and where no explicit 225 * type is included in the Intent, instead the <b>scheme</b> of the 226 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 227 * considered. Again like the action, if we are matching a scheme it 228 * must be listed by the component as one it can handle. 229 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 230 * by the activity as categories it handles. That is, if you include 231 * the categories {@link #CATEGORY_LAUNCHER} and 232 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 233 * with an intent that lists <em>both</em> of those categories. 234 * Activities will very often need to support the 235 * {@link #CATEGORY_DEFAULT} so that they can be found by 236 * {@link Context#startActivity Context.startActivity()}.</p> 237 * </ul> 238 * 239 * <p>For example, consider the Note Pad sample application that 240 * allows user to browse through a list of notes data and view details about 241 * individual items. Text in italics indicate places were you would replace a 242 * name with one specific to your own package.</p> 243 * 244 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 245 * package="<i>com.android.notepad</i>"> 246 * <application android:icon="@drawable/app_notes" 247 * android:label="@string/app_name"> 248 * 249 * <provider class=".NotePadProvider" 250 * android:authorities="<i>com.google.provider.NotePad</i>" /> 251 * 252 * <activity class=".NotesList" android:label="@string/title_notes_list"> 253 * <intent-filter> 254 * <action android:name="android.intent.action.MAIN" /> 255 * <category android:name="android.intent.category.LAUNCHER" /> 256 * </intent-filter> 257 * <intent-filter> 258 * <action android:name="android.intent.action.VIEW" /> 259 * <action android:name="android.intent.action.EDIT" /> 260 * <action android:name="android.intent.action.PICK" /> 261 * <category android:name="android.intent.category.DEFAULT" /> 262 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 263 * </intent-filter> 264 * <intent-filter> 265 * <action android:name="android.intent.action.GET_CONTENT" /> 266 * <category android:name="android.intent.category.DEFAULT" /> 267 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 268 * </intent-filter> 269 * </activity> 270 * 271 * <activity class=".NoteEditor" android:label="@string/title_note"> 272 * <intent-filter android:label="@string/resolve_edit"> 273 * <action android:name="android.intent.action.VIEW" /> 274 * <action android:name="android.intent.action.EDIT" /> 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 * 279 * <intent-filter> 280 * <action android:name="android.intent.action.INSERT" /> 281 * <category android:name="android.intent.category.DEFAULT" /> 282 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 283 * </intent-filter> 284 * 285 * </activity> 286 * 287 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 288 * android:theme="@android:style/Theme.Dialog"> 289 * <intent-filter android:label="@string/resolve_title"> 290 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 291 * <category android:name="android.intent.category.DEFAULT" /> 292 * <category android:name="android.intent.category.ALTERNATIVE" /> 293 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 294 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 295 * </intent-filter> 296 * </activity> 297 * 298 * </application> 299 * </manifest></pre> 300 * 301 * <p>The first activity, 302 * <code>com.android.notepad.NotesList</code>, serves as our main 303 * entry into the app. It can do three things as described by its three intent 304 * templates: 305 * <ol> 306 * <li><pre> 307 * <intent-filter> 308 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 309 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 310 * </intent-filter></pre> 311 * <p>This provides a top-level entry into the NotePad application: the standard 312 * MAIN action is a main entry point (not requiring any other information in 313 * the Intent), and the LAUNCHER category says that this entry point should be 314 * listed in the application launcher.</p> 315 * <li><pre> 316 * <intent-filter> 317 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 318 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 319 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 320 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 321 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 322 * </intent-filter></pre> 323 * <p>This declares the things that the activity can do on a directory of 324 * notes. The type being supported is given with the <type> tag, where 325 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 326 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 327 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 328 * The activity allows the user to view or edit the directory of data (via 329 * the VIEW and EDIT actions), or to pick a particular note and return it 330 * to the caller (via the PICK action). Note also the DEFAULT category 331 * supplied here: this is <em>required</em> for the 332 * {@link Context#startActivity Context.startActivity} method to resolve your 333 * activity when its component name is not explicitly specified.</p> 334 * <li><pre> 335 * <intent-filter> 336 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 337 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 338 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 339 * </intent-filter></pre> 340 * <p>This filter describes the ability return to the caller a note selected by 341 * the user without needing to know where it came from. The data type 342 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 343 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 344 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 345 * The GET_CONTENT action is similar to the PICK action, where the activity 346 * will return to its caller a piece of data selected by the user. Here, 347 * however, the caller specifies the type of data they desire instead of 348 * the type of data the user will be picking from.</p> 349 * </ol> 350 * 351 * <p>Given these capabilities, the following intents will resolve to the 352 * NotesList activity:</p> 353 * 354 * <ul> 355 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 356 * activities that can be used as top-level entry points into an 357 * application.</p> 358 * <li> <p><b>{ action=android.app.action.MAIN, 359 * category=android.app.category.LAUNCHER }</b> is the actual intent 360 * used by the Launcher to populate its top-level list.</p> 361 * <li> <p><b>{ action=android.intent.action.VIEW 362 * data=content://com.google.provider.NotePad/notes }</b> 363 * displays a list of all the notes under 364 * "content://com.google.provider.NotePad/notes", which 365 * the user can browse through and see the details on.</p> 366 * <li> <p><b>{ action=android.app.action.PICK 367 * data=content://com.google.provider.NotePad/notes }</b> 368 * provides a list of the notes under 369 * "content://com.google.provider.NotePad/notes", from which 370 * the user can pick a note whose data URL is returned back to the caller.</p> 371 * <li> <p><b>{ action=android.app.action.GET_CONTENT 372 * type=vnd.android.cursor.item/vnd.google.note }</b> 373 * is similar to the pick action, but allows the caller to specify the 374 * kind of data they want back so that the system can find the appropriate 375 * activity to pick something of that data type.</p> 376 * </ul> 377 * 378 * <p>The second activity, 379 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 380 * note entry and allows them to edit it. It can do two things as described 381 * by its two intent templates: 382 * <ol> 383 * <li><pre> 384 * <intent-filter android:label="@string/resolve_edit"> 385 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 386 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 387 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 388 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 389 * </intent-filter></pre> 390 * <p>The first, primary, purpose of this activity is to let the user interact 391 * with a single note, as decribed by the MIME type 392 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 393 * either VIEW a note or allow the user to EDIT it. Again we support the 394 * DEFAULT category to allow the activity to be launched without explicitly 395 * specifying its component.</p> 396 * <li><pre> 397 * <intent-filter> 398 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 399 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 400 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 401 * </intent-filter></pre> 402 * <p>The secondary use of this activity is to insert a new note entry into 403 * an existing directory of notes. This is used when the user creates a new 404 * note: the INSERT action is executed on the directory of notes, causing 405 * this activity to run and have the user create the new note data which 406 * it then adds to the content provider.</p> 407 * </ol> 408 * 409 * <p>Given these capabilities, the following intents will resolve to the 410 * NoteEditor activity:</p> 411 * 412 * <ul> 413 * <li> <p><b>{ action=android.intent.action.VIEW 414 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 415 * shows the user the content of note <var>{ID}</var>.</p> 416 * <li> <p><b>{ action=android.app.action.EDIT 417 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 418 * allows the user to edit the content of note <var>{ID}</var>.</p> 419 * <li> <p><b>{ action=android.app.action.INSERT 420 * data=content://com.google.provider.NotePad/notes }</b> 421 * creates a new, empty note in the notes list at 422 * "content://com.google.provider.NotePad/notes" 423 * and allows the user to edit it. If they keep their changes, the URI 424 * of the newly created note is returned to the caller.</p> 425 * </ul> 426 * 427 * <p>The last activity, 428 * <code>com.android.notepad.TitleEditor</code>, allows the user to 429 * edit the title of a note. This could be implemented as a class that the 430 * application directly invokes (by explicitly setting its component in 431 * the Intent), but here we show a way you can publish alternative 432 * operations on existing data:</p> 433 * 434 * <pre> 435 * <intent-filter android:label="@string/resolve_title"> 436 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 437 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 438 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 439 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 440 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 441 * </intent-filter></pre> 442 * 443 * <p>In the single intent template here, we 444 * have created our own private action called 445 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 446 * edit the title of a note. It must be invoked on a specific note 447 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 448 * view and edit actions, but here displays and edits the title contained 449 * in the note data. 450 * 451 * <p>In addition to supporting the default category as usual, our title editor 452 * also supports two other standard categories: ALTERNATIVE and 453 * SELECTED_ALTERNATIVE.
