It 49 * can be used with {@link Context#startActivity(Intent) startActivity} to 50 * launch an {@link android.app.Activity}, 51 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 52 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 53 * and {@link android.content.Context#startService} or 54 * {@link android.content.Context#bindService} to communicate with a 55 * background {@link android.app.Service}. 56 * 57 * <p>An Intent provides a facility for performing late runtime binding between 58 * the code in different applications. Its most significant use is in the 59 * launching of activities, where it can be thought of as the glue between 60 * activities. It is 61 * basically a passive data structure holding an abstract description of an 62 * action to be performed. The primary pieces of information in an intent 63 * are:</p> 64 * 65 * <ul> 66 * <li> <p><b>action</b> -- The general action to be performed, such as 67 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 68 * etc.</p> 69 * </li> 70 * <li> <p><b>data</b> -- The data to operate on, such as a person record 71 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 72 * </li> 73 * </ul> 74 * 75 * 76 * <p>Some examples of action/data pairs are:</p> 77 * 78 * <ul> 79 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 80 * information about the person whose identifier is "1".</p> 81 * </li> 82 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 83 * the phone dialer with the person filled in.</p> 84 * </li> 85 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 86 * the phone dialer with the given number filled in. Note how the 87 * VIEW action does what what is considered the most reasonable thing for 88 * a particular URI.</p> 89 * </li> 90 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 91 * the phone dialer with the given number filled in.</p> 92 * </li> 93 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 94 * information about the person whose identifier is "1".</p> 95 * </li> 96 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 97 * a list of people, which the user can browse through. This example is a 98 * typical top-level entry into the Contacts application, showing you the 99 * list of people. Selecting a particular person to view would result in a 100 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 101 * being used to start an activity to display that person.</p> 102 * </li> 103 * </ul> 104 * 105 * <p>In addition to these primary attributes, there are a number of secondary 106 * attributes that you can also include with an intent:</p> 107 * 108 * <ul> 109 * <li> <p><b>category</b> -- Gives additional information about the action 110 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 111 * appear in the Launcher as a top-level application, while 112 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 113 * of alternative actions the user can perform on a piece of data.</p> 114 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 115 * intent data. Normally the type is inferred from the data itself. 116 * By setting this attribute, you disable that evaluation and force 117 * an explicit type.</p> 118 * <li> <p><b>component</b> -- Specifies an explicit name of a component 119 * class to use for the intent. Normally this is determined by looking 120 * at the other information in the intent (the action, data/type, and 121 * categories) and matching that with a component that can handle it. 122 * If this attribute is set then none of the evaluation is performed, 123 * and this component is used exactly as is. By specifying this attribute, 124 * all of the other Intent attributes become optional.</p> 125 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 126 * This can be used to provide extended information to the component. 127 * For example, if we have a action to send an e-mail message, we could 128 * also include extra pieces of data here to supply a subject, body, 129 * etc.</p> 130 * </ul> 131 * 132 * <p>Here are some examples of other operations you can specify as intents 133 * using these additional parameters:</p> 134 * 135 * <ul> 136 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 137 * Launch the home screen.</p> 138 * </li> 139 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 140 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 141 * vnd.android.cursor.item/phone}</i></b> 142 * -- Display the list of people's phone numbers, allowing the user to 143 * browse through them and pick one and return it to the parent activity.</p> 144 * </li> 145 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 146 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 147 * -- Display all pickers for data that can be opened with 148 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 149 * allowing the user to pick one of them and then some data inside of it 150 * and returning the resulting URI to the caller. This can be used, 151 * for example, in an e-mail application to allow the user to pick some 152 * data to include as an attachment.</p> 153 * </li> 154 * </ul> 155 * 156 * <p>There are a variety of standard Intent action and category constants 157 * defined in the Intent class, but applications can also define their own. 158 * These strings use java style scoping, to ensure they are unique -- for 159 * example, the standard {@link #ACTION_VIEW} is called 160 * "android.intent.action.VIEW".</p> 161 * 162 * <p>Put together, the set of actions, data types, categories, and extra data 163 * defines a language for the system allowing for the expression of phrases 164 * such as "call john smith's cell". As applications are added to the system, 165 * they can extend this language by adding new actions, types, and categories, or 166 * they can modify the behavior of existing phrases by supplying their own 167 * activities that handle them.</p> 168 * 169 * <a name="IntentResolution"></a> 170 * <h3>Intent Resolution</h3> 171 * 172 * <p>There are two primary forms of intents you will use. 173 * 174 * <ul> 175 * <li> <p><b>Explicit Intents</b> have specified a component (via 176 * {@link #setComponent} or {@link #setClass}), which provides the exact 177 * class to be run. Often these will not include any other information, 178 * simply being a way for an application to launch various internal 179 * activities it has as the user interacts with the application. 180 * 181 * <li> <p><b>Implicit Intents</b> have not specified a component; 182 * instead, they must include enough information for the system to 183 * determine which of the available components is best to run for that 184 * intent. 185 * </ul> 186 * 187 * <p>When using implicit intents, given such an arbitrary intent we need to 188 * know what to do with it. This is handled by the process of <em>Intent 189 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 190 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 191 * more activities/receivers) that can handle it.</p> 192 * 193 * <p>The intent resolution mechanism basically revolves around matching an 194 * Intent against all of the <intent-filter> descriptions in the 195 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 196 * objects explicitly registered with {@link Context#registerReceiver}.) More 197 * details on this can be found in the documentation on the {@link 198 * IntentFilter} class.</p> 199 * 200 * <p>There are three pieces of information in the Intent that are used for 201 * resolution: the action, type, and category. Using this information, a query 202 * is done on the {@link PackageManager} for a component that can handle the 203 * intent. The appropriate component is determined based on the intent 204 * information supplied in the <code>AndroidManifest.xml</code> file as 205 * follows:</p> 206 * 207 * <ul> 208 * <li> <p>The <b>action</b>, if given, must be listed by the component as 209 * one it handles.</p> 210 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 211 * already supplied in the Intent. Like the action, if a type is 212 * included in the intent (either explicitly or implicitly in its 213 * data), then this must be listed by the component as one it handles.</p> 214 * <li> For data that is not a <code>content:</code> URI and where no explicit 215 * type is included in the Intent, instead the <b>scheme</b> of the 216 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 217 * considered. Again like the action, if we are matching a scheme it 218 * must be listed by the component as one it can handle. 219 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 220 * by the activity as categories it handles. That is, if you include 221 * the categories {@link #CATEGORY_LAUNCHER} and 222 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 223 * with an intent that lists <em>both</em> of those categories. 224 * Activities will very often need to support the 225 * {@link #CATEGORY_DEFAULT} so that they can be found by 226 * {@link Context#startActivity Context.startActivity()}.</p> 227 * </ul> 228 * 229 * <p>For example, consider the Note Pad sample application that 230 * allows user to browse through a list of notes data and view details about 231 * individual items. Text in italics indicate places were you would replace a 232 * name with one specific to your own package.</p> 233 * 234 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 235 * package="<i>com.android.notepad</i>"> 236 * <application android:icon="@drawable/app_notes" 237 * android:label="@string/app_name"> 238 * 239 * <provider class=".NotePadProvider" 240 * android:authorities="<i>com.google.provider.NotePad</i>" /> 241 * 242 * <activity class=".NotesList" android:label="@string/title_notes_list"> 243 * <intent-filter> 244 * <action android:name="android.intent.action.MAIN" /> 245 * <category android:name="android.intent.category.LAUNCHER" /> 246 * </intent-filter> 247 * <intent-filter> 248 * <action android:name="android.intent.action.VIEW" /> 249 * <action android:name="android.intent.action.EDIT" /> 250 * <action android:name="android.intent.action.PICK" /> 251 * <category android:name="android.intent.category.DEFAULT" /> 252 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 253 * </intent-filter> 254 * <intent-filter> 255 * <action android:name="android.intent.action.GET_CONTENT" /> 256 * <category android:name="android.intent.category.DEFAULT" /> 257 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 258 * </intent-filter> 259 * </activity> 260 * 261 * <activity class=".NoteEditor" android:label="@string/title_note"> 262 * <intent-filter android:label="@string/resolve_edit"> 263 * <action android:name="android.intent.action.VIEW" /> 264 * <action android:name="android.intent.action.EDIT" /> 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 * 269 * <intent-filter> 270 * <action android:name="android.intent.action.INSERT" /> 271 * <category android:name="android.intent.category.DEFAULT" /> 272 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 273 * </intent-filter> 274 * 275 * </activity> 276 * 277 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 278 * android:theme="@android:style/Theme.Dialog"> 279 * <intent-filter android:label="@string/resolve_title"> 280 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 281 * <category android:name="android.intent.category.DEFAULT" /> 282 * <category android:name="android.intent.category.ALTERNATIVE" /> 283 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 284 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 285 * </intent-filter> 286 * </activity> 287 * 288 * </application> 289 * </manifest></pre> 290 * 291 * <p>The first activity, 292 * <code>com.android.notepad.NotesList</code>, serves as our main 293 * entry into the app. It can do three things as described by its three intent 294 * templates: 295 * <ol> 296 * <li><pre> 297 * <intent-filter> 298 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 299 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 300 * </intent-filter></pre> 301 * <p>This provides a top-level entry into the NotePad application: the standard 302 * MAIN action is a main entry point (not requiring any other information in 303 * the Intent), and the LAUNCHER category says that this entry point should be 304 * listed in the application launcher.</p> 305 * <li><pre> 306 * <intent-filter> 307 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 308 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 309 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 310 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 311 * <data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 312 * </intent-filter></pre> 313 * <p>This declares the things that the activity can do on a directory of 314 * notes. The type being supported is given with the <type> tag, where 315 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 316 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 317 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 318 * The activity allows the user to view or edit the directory of data (via 319 * the VIEW and EDIT actions), or to pick a particular note and return it 320 * to the caller (via the PICK action). Note also the DEFAULT category 321 * supplied here: this is <em>required</em> for the 322 * {@link Context#startActivity Context.startActivity} method to resolve your 323 * activity when its component name is not explicitly specified.</p> 324 * <li><pre> 325 * <intent-filter> 326 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 327 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 328 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 329 * </intent-filter></pre> 330 * <p>This filter describes the ability return to the caller a note selected by 331 * the user without needing to know where it came from. The data type 332 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 333 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 334 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 335 * The GET_CONTENT action is similar to the PICK action, where the activity 336 * will return to its caller a piece of data selected by the user. Here, 337 * however, the caller specifies the type of data they desire instead of 338 * the type of data the user will be picking from.</p> 339 * </ol> 340 * 341 * <p>Given these capabilities, the following intents will resolve to the 342 * NotesList activity:</p> 343 * 344 * <ul> 345 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 346 * activities that can be used as top-level entry points into an 347 * application.</p> 348 * <li> <p><b>{ action=android.app.action.MAIN, 349 * category=android.app.category.LAUNCHER }</b> is the actual intent 350 * used by the Launcher to populate its top-level list.</p> 351 * <li> <p><b>{ action=android.intent.action.VIEW 352 * data=content://com.google.provider.NotePad/notes }</b> 353 * displays a list of all the notes under 354 * "content://com.google.provider.NotePad/notes", which 355 * the user can browse through and see the details on.</p> 356 * <li> <p><b>{ action=android.app.action.PICK 357 * data=content://com.google.provider.NotePad/notes }</b> 358 * provides a list of the notes under 359 * "content://com.google.provider.NotePad/notes", from which 360 * the user can pick a note whose data URL is returned back to the caller.</p> 361 * <li> <p><b>{ action=android.app.action.GET_CONTENT 362 * type=vnd.android.cursor.item/vnd.google.note }</b> 363 * is similar to the pick action, but allows the caller to specify the 364 * kind of data they want back so that the system can find the appropriate 365 * activity to pick something of that data type.</p> 366 * </ul> 367 * 368 * <p>The second activity, 369 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 370 * note entry and allows them to edit it. It can do two things as described 371 * by its two intent templates: 372 * <ol> 373 * <li><pre> 374 * <intent-filter android:label="@string/resolve_edit"> 375 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 376 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 377 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 378 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 379 * </intent-filter></pre> 380 * <p>The first, primary, purpose of this activity is to let the user interact 381 * with a single note, as decribed by the MIME type 382 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 383 * either VIEW a note or allow the user to EDIT it. Again we support the 384 * DEFAULT category to allow the activity to be launched without explicitly 385 * specifying its component.</p> 386 * <li><pre> 387 * <intent-filter> 388 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 389 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 390 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 391 * </intent-filter></pre> 392 * <p>The secondary use of this activity is to insert a new note entry into 393 * an existing directory of notes. This is used when the user creates a new 394 * note: the INSERT action is executed on the directory of notes, causing 395 * this activity to run and have the user create the new note data which 396 * it then adds to the content provider.</p> 397 * </ol> 398 * 399 * <p>Given these capabilities, the following intents will resolve to the 400 * NoteEditor activity:</p> 401 * 402 * <ul> 403 * <li> <p><b>{ action=android.intent.action.VIEW 404 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 405 * shows the user the content of note <var>{ID}</var>.</p> 406 * <li> <p><b>{ action=android.app.action.EDIT 407 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 408 * allows the user to edit the content of note <var>{ID}</var>.</p> 409 * <li> <p><b>{ action=android.app.action.INSERT 410 * data=content://com.google.provider.NotePad/notes }</b> 411 * creates a new, empty note in the notes list at 412 * "content://com.google.provider.NotePad/notes" 413 * and allows the user to edit it. If they keep their changes, the URI 414 * of the newly created note is returned to the caller.</p> 415 * </ul> 416 * 417 * <p>The last activity, 418 * <code>com.android.notepad.TitleEditor</code>, allows the user to 419 * edit the title of a note. This could be implemented as a class that the 420 * application directly invokes (by explicitly setting its component in 421 * the Intent), but here we show a way you can publish alternative 422 * operations on existing data:</p> 423 * 424 * <pre> 425 * <intent-filter android:label="@string/resolve_title"> 426 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 427 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 428 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 429 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 430 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 431 * </intent-filter></pre> 432 * 433 * <p>In the single intent template here, we 434 * have created our own private action called 435 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 436 * edit the title of a note. It must be invoked on a specific note 437 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 438 * view and edit actions, but here displays and edits the title contained 439 * in the note data. 440 * 441 * <p>In addition to supporting the default category as usual, our title editor 442 * also supports two other standard categories: ALTERNATIVE and 443 * SELECTED_ALTERNATIVE.
