It 50 * can be used with {@link Context#startActivity(Intent) startActivity} to 51 * launch an {@link android.app.Activity}, 52 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 53 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 54 * and {@link android.content.Context#startService} or 55 * {@link android.content.Context#bindService} to communicate with a 56 * background {@link android.app.Service}. 57 * 58 * <p>An Intent provides a facility for performing late runtime binding between the code in 59 * different applications. Its most significant use is in the launching of activities, where it 60 * can be thought of as the glue between activities. It is basically a passive data structure 61 * holding an abstract description of an action to be performed.</p> 62 * 63 * <div class="special reference"> 64 * <h3>Developer Guides</h3> 65 * <p>For information about how to create and resolve intents, read the 66 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 67 * developer guide.</p> 68 * </div> 69 * 70 * <a name="IntentStructure"></a> 71 * <h3>Intent Structure</h3> 72 * <p>The primary pieces of information in an intent are:</p> 73 * 74 * <ul> 75 * <li> <p><b>action</b> -- The general action to be performed, such as 76 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 77 * etc.</p> 78 * </li> 79 * <li> <p><b>data</b> -- The data to operate on, such as a person record 80 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 81 * </li> 82 * </ul> 83 * 84 * 85 * <p>Some examples of action/data pairs are:</p> 86 * 87 * <ul> 88 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 89 * information about the person whose identifier is "1".</p> 90 * </li> 91 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 92 * the phone dialer with the person filled in.</p> 93 * </li> 94 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 95 * the phone dialer with the given number filled in. Note how the 96 * VIEW action does what what is considered the most reasonable thing for 97 * a particular URI.</p> 98 * </li> 99 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 100 * the phone dialer with the given number filled in.</p> 101 * </li> 102 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 103 * information about the person whose identifier is "1".</p> 104 * </li> 105 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 106 * a list of people, which the user can browse through. This example is a 107 * typical top-level entry into the Contacts application, showing you the 108 * list of people. Selecting a particular person to view would result in a 109 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 110 * being used to start an activity to display that person.</p> 111 * </li> 112 * </ul> 113 * 114 * <p>In addition to these primary attributes, there are a number of secondary 115 * attributes that you can also include with an intent:</p> 116 * 117 * <ul> 118 * <li> <p><b>category</b> -- Gives additional information about the action 119 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 120 * appear in the Launcher as a top-level application, while 121 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 122 * of alternative actions the user can perform on a piece of data.</p> 123 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 124 * intent data. Normally the type is inferred from the data itself. 125 * By setting this attribute, you disable that evaluation and force 126 * an explicit type.</p> 127 * <li> <p><b>component</b> -- Specifies an explicit name of a component 128 * class to use for the intent. Normally this is determined by looking 129 * at the other information in the intent (the action, data/type, and 130 * categories) and matching that with a component that can handle it. 131 * If this attribute is set then none of the evaluation is performed, 132 * and this component is used exactly as is. By specifying this attribute, 133 * all of the other Intent attributes become optional.</p> 134 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 135 * This can be used to provide extended information to the component. 136 * For example, if we have a action to send an e-mail message, we could 137 * also include extra pieces of data here to supply a subject, body, 138 * etc.</p> 139 * </ul> 140 * 141 * <p>Here are some examples of other operations you can specify as intents 142 * using these additional parameters:</p> 143 * 144 * <ul> 145 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 146 * Launch the home screen.</p> 147 * </li> 148 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 149 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 150 * vnd.android.cursor.item/phone}</i></b> 151 * -- Display the list of people's phone numbers, allowing the user to 152 * browse through them and pick one and return it to the parent activity.</p> 153 * </li> 154 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 155 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 156 * -- Display all pickers for data that can be opened with 157 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 158 * allowing the user to pick one of them and then some data inside of it 159 * and returning the resulting URI to the caller. This can be used, 160 * for example, in an e-mail application to allow the user to pick some 161 * data to include as an attachment.</p> 162 * </li> 163 * </ul> 164 * 165 * <p>There are a variety of standard Intent action and category constants 166 * defined in the Intent class, but applications can also define their own. 167 * These strings use java style scoping, to ensure they are unique -- for 168 * example, the standard {@link #ACTION_VIEW} is called 169 * "android.intent.action.VIEW".</p> 170 * 171 * <p>Put together, the set of actions, data types, categories, and extra data 172 * defines a language for the system allowing for the expression of phrases 173 * such as "call john smith's cell". As applications are added to the system, 174 * they can extend this language by adding new actions, types, and categories, or 175 * they can modify the behavior of existing phrases by supplying their own 176 * activities that handle them.</p> 177 * 178 * <a name="IntentResolution"></a> 179 * <h3>Intent Resolution</h3> 180 * 181 * <p>There are two primary forms of intents you will use. 182 * 183 * <ul> 184 * <li> <p><b>Explicit Intents</b> have specified a component (via 185 * {@link #setComponent} or {@link #setClass}), which provides the exact 186 * class to be run. Often these will not include any other information, 187 * simply being a way for an application to launch various internal 188 * activities it has as the user interacts with the application. 189 * 190 * <li> <p><b>Implicit Intents</b> have not specified a component; 191 * instead, they must include enough information for the system to 192 * determine which of the available components is best to run for that 193 * intent. 194 * </ul> 195 * 196 * <p>When using implicit intents, given such an arbitrary intent we need to 197 * know what to do with it. This is handled by the process of <em>Intent 198 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 199 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 200 * more activities/receivers) that can handle it.</p> 201 * 202 * <p>The intent resolution mechanism basically revolves around matching an 203 * Intent against all of the <intent-filter> descriptions in the 204 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 205 * objects explicitly registered with {@link Context#registerReceiver}.) More 206 * details on this can be found in the documentation on the {@link 207 * IntentFilter} class.</p> 208 * 209 * <p>There are three pieces of information in the Intent that are used for 210 * resolution: the action, type, and category. Using this information, a query 211 * is done on the {@link PackageManager} for a component that can handle the 212 * intent. The appropriate component is determined based on the intent 213 * information supplied in the <code>AndroidManifest.xml</code> file as 214 * follows:</p> 215 * 216 * <ul> 217 * <li> <p>The <b>action</b>, if given, must be listed by the component as 218 * one it handles.</p> 219 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 220 * already supplied in the Intent. Like the action, if a type is 221 * included in the intent (either explicitly or implicitly in its 222 * data), then this must be listed by the component as one it handles.</p> 223 * <li> For data that is not a <code>content:</code> URI and where no explicit 224 * type is included in the Intent, instead the <b>scheme</b> of the 225 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 226 * considered. Again like the action, if we are matching a scheme it 227 * must be listed by the component as one it can handle. 228 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 229 * by the activity as categories it handles. That is, if you include 230 * the categories {@link #CATEGORY_LAUNCHER} and 231 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 232 * with an intent that lists <em>both</em> of those categories. 233 * Activities will very often need to support the 234 * {@link #CATEGORY_DEFAULT} so that they can be found by 235 * {@link Context#startActivity Context.startActivity()}.</p> 236 * </ul> 237 * 238 * <p>For example, consider the Note Pad sample application that 239 * allows user to browse through a list of notes data and view details about 240 * individual items. Text in italics indicate places were you would replace a 241 * name with one specific to your own package.</p> 242 * 243 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 244 * package="<i>com.android.notepad</i>"> 245 * <application android:icon="@drawable/app_notes" 246 * android:label="@string/app_name"> 247 * 248 * <provider class=".NotePadProvider" 249 * android:authorities="<i>com.google.provider.NotePad</i>" /> 250 * 251 * <activity class=".NotesList" android:label="@string/title_notes_list"> 252 * <intent-filter> 253 * <action android:name="android.intent.action.MAIN" /> 254 * <category android:name="android.intent.category.LAUNCHER" /> 255 * </intent-filter> 256 * <intent-filter> 257 * <action android:name="android.intent.action.VIEW" /> 258 * <action android:name="android.intent.action.EDIT" /> 259 * <action android:name="android.intent.action.PICK" /> 260 * <category android:name="android.intent.category.DEFAULT" /> 261 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 262 * </intent-filter> 263 * <intent-filter> 264 * <action android:name="android.intent.action.GET_CONTENT" /> 265 * <category android:name="android.intent.category.DEFAULT" /> 266 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 267 * </intent-filter> 268 * </activity> 269 * 270 * <activity class=".NoteEditor" android:label="@string/title_note"> 271 * <intent-filter android:label="@string/resolve_edit"> 272 * <action android:name="android.intent.action.VIEW" /> 273 * <action android:name="android.intent.action.EDIT" /> 274 * <category android:name="android.intent.category.DEFAULT" /> 275 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 276 * </intent-filter> 277 * 278 * <intent-filter> 279 * <action android:name="android.intent.action.INSERT" /> 280 * <category android:name="android.intent.category.DEFAULT" /> 281 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 282 * </intent-filter> 283 * 284 * </activity> 285 * 286 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 287 * android:theme="@android:style/Theme.Dialog"> 288 * <intent-filter android:label="@string/resolve_title"> 289 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 290 * <category android:name="android.intent.category.DEFAULT" /> 291 * <category android:name="android.intent.category.ALTERNATIVE" /> 292 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 293 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 294 * </intent-filter> 295 * </activity> 296 * 297 * </application> 298 * </manifest></pre> 299 * 300 * <p>The first activity, 301 * <code>com.android.notepad.NotesList</code>, serves as our main 302 * entry into the app. It can do three things as described by its three intent 303 * templates: 304 * <ol> 305 * <li><pre> 306 * <intent-filter> 307 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 308 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 309 * </intent-filter></pre> 310 * <p>This provides a top-level entry into the NotePad application: the standard 311 * MAIN action is a main entry point (not requiring any other information in 312 * the Intent), and the LAUNCHER category says that this entry point should be 313 * listed in the application launcher.</p> 314 * <li><pre> 315 * <intent-filter> 316 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 317 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 318 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 319 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 320 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 321 * </intent-filter></pre> 322 * <p>This declares the things that the activity can do on a directory of 323 * notes. The type being supported is given with the <type> tag, where 324 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 325 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 326 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 327 * The activity allows the user to view or edit the directory of data (via 328 * the VIEW and EDIT actions), or to pick a particular note and return it 329 * to the caller (via the PICK action). Note also the DEFAULT category 330 * supplied here: this is <em>required</em> for the 331 * {@link Context#startActivity Context.startActivity} method to resolve your 332 * activity when its component name is not explicitly specified.</p> 333 * <li><pre> 334 * <intent-filter> 335 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 336 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 337 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 338 * </intent-filter></pre> 339 * <p>This filter describes the ability return to the caller a note selected by 340 * the user without needing to know where it came from. The data type 341 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 342 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 343 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 344 * The GET_CONTENT action is similar to the PICK action, where the activity 345 * will return to its caller a piece of data selected by the user. Here, 346 * however, the caller specifies the type of data they desire instead of 347 * the type of data the user will be picking from.</p> 348 * </ol> 349 * 350 * <p>Given these capabilities, the following intents will resolve to the 351 * NotesList activity:</p> 352 * 353 * <ul> 354 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 355 * activities that can be used as top-level entry points into an 356 * application.</p> 357 * <li> <p><b>{ action=android.app.action.MAIN, 358 * category=android.app.category.LAUNCHER }</b> is the actual intent 359 * used by the Launcher to populate its top-level list.</p> 360 * <li> <p><b>{ action=android.intent.action.VIEW 361 * data=content://com.google.provider.NotePad/notes }</b> 362 * displays a list of all the notes under 363 * "content://com.google.provider.NotePad/notes", which 364 * the user can browse through and see the details on.</p> 365 * <li> <p><b>{ action=android.app.action.PICK 366 * data=content://com.google.provider.NotePad/notes }</b> 367 * provides a list of the notes under 368 * "content://com.google.provider.NotePad/notes", from which 369 * the user can pick a note whose data URL is returned back to the caller.</p> 370 * <li> <p><b>{ action=android.app.action.GET_CONTENT 371 * type=vnd.android.cursor.item/vnd.google.note }</b> 372 * is similar to the pick action, but allows the caller to specify the 373 * kind of data they want back so that the system can find the appropriate 374 * activity to pick something of that data type.</p> 375 * </ul> 376 * 377 * <p>The second activity, 378 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 379 * note entry and allows them to edit it. It can do two things as described 380 * by its two intent templates: 381 * <ol> 382 * <li><pre> 383 * <intent-filter android:label="@string/resolve_edit"> 384 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 385 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 386 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 387 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 388 * </intent-filter></pre> 389 * <p>The first, primary, purpose of this activity is to let the user interact 390 * with a single note, as decribed by the MIME type 391 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 392 * either VIEW a note or allow the user to EDIT it. Again we support the 393 * DEFAULT category to allow the activity to be launched without explicitly 394 * specifying its component.</p> 395 * <li><pre> 396 * <intent-filter> 397 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 398 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 399 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 400 * </intent-filter></pre> 401 * <p>The secondary use of this activity is to insert a new note entry into 402 * an existing directory of notes. This is used when the user creates a new 403 * note: the INSERT action is executed on the directory of notes, causing 404 * this activity to run and have the user create the new note data which 405 * it then adds to the content provider.</p> 406 * </ol> 407 * 408 * <p>Given these capabilities, the following intents will resolve to the 409 * NoteEditor activity:</p> 410 * 411 * <ul> 412 * <li> <p><b>{ action=android.intent.action.VIEW 413 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 414 * shows the user the content of note <var>{ID}</var>.</p> 415 * <li> <p><b>{ action=android.app.action.EDIT 416 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 417 * allows the user to edit the content of note <var>{ID}</var>.</p> 418 * <li> <p><b>{ action=android.app.action.INSERT 419 * data=content://com.google.provider.NotePad/notes }</b> 420 * creates a new, empty note in the notes list at 421 * "content://com.google.provider.NotePad/notes" 422 * and allows the user to edit it. If they keep their changes, the URI 423 * of the newly created note is returned to the caller.</p> 424 * </ul> 425 * 426 * <p>The last activity, 427 * <code>com.android.notepad.TitleEditor</code>, allows the user to 428 * edit the title of a note. This could be implemented as a class that the 429 * application directly invokes (by explicitly setting its component in 430 * the Intent), but here we show a way you can publish alternative 431 * operations on existing data:</p> 432 * 433 * <pre> 434 * <intent-filter android:label="@string/resolve_title"> 435 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 436 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 437 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 438 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 439 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 440 * </intent-filter></pre> 441 * 442 * <p>In the single intent template here, we 443 * have created our own private action called 444 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 445 * edit the title of a note. It must be invoked on a specific note 446 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 447 * view and edit actions, but here displays and edits the title contained 448 * in the note data. 449 * 450 * <p>In addition to supporting the default category as usual, our title editor 451 * also supports two other standard categories: ALTERNATIVE and 452 * SELECTED_ALTERNATIVE.
