It 48 * can be used with {@link Context#startActivity(Intent) startActivity} to 49 * launch an {@link android.app.Activity}, 50 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 51 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 52 * and {@link android.content.Context#startService} or 53 * {@link android.content.Context#bindService} to communicate with a 54 * background {@link android.app.Service}. 55 * 56 * <p>An Intent provides a facility for performing late runtime binding between 57 * the code in different applications. Its most significant use is in the 58 * launching of activities, where it can be thought of as the glue between 59 * activities. It is 60 * basically a passive data structure holding an abstract description of an 61 * action to be performed. The primary pieces of information in an intent 62 * are:</p> 63 * 64 * <ul> 65 * <li> <p><b>action</b> -- The general action to be performed, such as 66 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 67 * etc.</p> 68 * </li> 69 * <li> <p><b>data</b> -- The data to operate on, such as a person record 70 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 71 * </li> 72 * </ul> 73 * 74 * 75 * <p>Some examples of action/data pairs are:</p> 76 * 77 * <ul> 78 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/1</i></b> -- Display 79 * information about the person whose identifier is "1".</p> 80 * </li> 81 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/1</i></b> -- Display 82 * the phone dialer with the person filled in.</p> 83 * </li> 84 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 85 * the phone dialer with the given number filled in. Note how the 86 * VIEW action does what what is considered the most reasonable thing for 87 * a particular URI.</p> 88 * </li> 89 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 90 * the phone dialer with the given number filled in.</p> 91 * </li> 92 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/1</i></b> -- Edit 93 * information about the person whose identifier is "1".</p> 94 * </li> 95 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/</i></b> -- Display 96 * a list of people, which the user can browse through. This example is a 97 * typical top-level entry into the Contacts application, showing you the 98 * list of people. Selecting a particular person to view would result in a 99 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } 100 * being used to start an activity to display that person.</p> 101 * </li> 102 * </ul> 103 * 104 * <p>In addition to these primary attributes, there are a number of secondary 105 * attributes that you can also include with an intent:</p> 106 * 107 * <ul> 108 * <li> <p><b>category</b> -- Gives additional information about the action 109 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 110 * appear in the Launcher as a top-level application, while 111 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 112 * of alternative actions the user can perform on a piece of data.</p> 113 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 114 * intent data. Normally the type is inferred from the data itself. 115 * By setting this attribute, you disable that evaluation and force 116 * an explicit type.</p> 117 * <li> <p><b>component</b> -- Specifies an explicit name of a component 118 * class to use for the intent. Normally this is determined by looking 119 * at the other information in the intent (the action, data/type, and 120 * categories) and matching that with a component that can handle it. 121 * If this attribute is set then none of the evaluation is performed, 122 * and this component is used exactly as is. By specifying this attribute, 123 * all of the other Intent attributes become optional.</p> 124 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 125 * This can be used to provide extended information to the component. 126 * For example, if we have a action to send an e-mail message, we could 127 * also include extra pieces of data here to supply a subject, body, 128 * etc.</p> 129 * </ul> 130 * 131 * <p>Here are some examples of other operations you can specify as intents 132 * using these additional parameters:</p> 133 * 134 * <ul> 135 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 136 * Launch the home screen.</p> 137 * </li> 138 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 139 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 140 * vnd.android.cursor.item/phone}</i></b> 141 * -- Display the list of people's phone numbers, allowing the user to 142 * browse through them and pick one and return it to the parent activity.</p> 143 * </li> 144 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 145 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 146 * -- Display all pickers for data that can be opened with 147 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 148 * allowing the user to pick one of them and then some data inside of it 149 * and returning the resulting URI to the caller. This can be used, 150 * for example, in an e-mail application to allow the user to pick some 151 * data to include as an attachment.</p> 152 * </li> 153 * </ul> 154 * 155 * <p>There are a variety of standard Intent action and category constants 156 * defined in the Intent class, but applications can also define their own. 157 * These strings use java style scoping, to ensure they are unique -- for 158 * example, the standard {@link #ACTION_VIEW} is called 159 * "android.app.action.VIEW".</p> 160 * 161 * <p>Put together, the set of actions, data types, categories, and extra data 162 * defines a language for the system allowing for the expression of phrases 163 * such as "call john smith's cell". As applications are added to the system, 164 * they can extend this language by adding new actions, types, and categories, or 165 * they can modify the behavior of existing phrases by supplying their own 166 * activities that handle them.</p> 167 * 168 * <a name="IntentResolution"></a> 169 * <h3>Intent Resolution</h3> 170 * 171 * <p>There are two primary forms of intents you will use. 172 * 173 * <ul> 174 * <li> <p><b>Explicit Intents</b> have specified a component (via 175 * {@link #setComponent} or {@link #setClass}), which provides the exact 176 * class to be run. Often these will not include any other information, 177 * simply being a way for an application to launch various internal 178 * activities it has as the user interacts with the application. 179 * 180 * <li> <p><b>Implicit Intents</b> have not specified a component; 181 * instead, they must include enough information for the system to 182 * determine which of the available components is best to run for that 183 * intent. 184 * </ul> 185 * 186 * <p>When using implicit intents, given such an arbitrary intent we need to 187 * know what to do with it. This is handled by the process of <em>Intent 188 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 189 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 190 * more activities/receivers) that can handle it.</p> 191 * 192 * <p>The intent resolution mechanism basically revolves around matching an 193 * Intent against all of the <intent-filter> descriptions in the 194 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 195 * objects explicitly registered with {@link Context#registerReceiver}.) More 196 * details on this can be found in the documentation on the {@link 197 * IntentFilter} class.</p> 198 * 199 * <p>There are three pieces of information in the Intent that are used for 200 * resolution: the action, type, and category. Using this information, a query 201 * is done on the {@link PackageManager} for a component that can handle the 202 * intent. The appropriate component is determined based on the intent 203 * information supplied in the <code>AndroidManifest.xml</code> file as 204 * follows:</p> 205 * 206 * <ul> 207 * <li> <p>The <b>action</b>, if given, must be listed by the component as 208 * one it handles.</p> 209 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 210 * already supplied in the Intent. Like the action, if a type is 211 * included in the intent (either explicitly or implicitly in its 212 * data), then this must be listed by the component as one it handles.</p> 213 * <li> For data that is not a <code>content:</code> URI and where no explicit 214 * type is included in the Intent, instead the <b>scheme</b> of the 215 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 216 * considered. Again like the action, if we are matching a scheme it 217 * must be listed by the component as one it can handle. 218 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 219 * by the activity as categories it handles. That is, if you include 220 * the categories {@link #CATEGORY_LAUNCHER} and 221 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 222 * with an intent that lists <em>both</em> of those categories. 223 * Activities will very often need to support the 224 * {@link #CATEGORY_DEFAULT} so that they can be found by 225 * {@link Context#startActivity Context.startActivity()}.</p> 226 * </ul> 227 * 228 * <p>For example, consider the Note Pad sample application that 229 * allows user to browse through a list of notes data and view details about 230 * individual items. Text in italics indicate places were you would replace a 231 * name with one specific to your own package.</p> 232 * 233 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 234 * package="<i>com.android.notepad</i>"> 235 * <application android:icon="@drawable/app_notes" 236 * android:label="@string/app_name"> 237 * 238 * <provider class=".NotePadProvider" 239 * android:authorities="<i>com.google.provider.NotePad</i>" /> 240 * 241 * <activity class=".NotesList" android:label="@string/title_notes_list"> 242 * <intent-filter> 243 * <action android:value="android.intent.action.MAIN" /> 244 * <category android:value="android.intent.category.LAUNCHER" /> 245 * </intent-filter> 246 * <intent-filter> 247 * <action android:value="android.intent.action.VIEW" /> 248 * <action android:value="android.intent.action.EDIT" /> 249 * <action android:value="android.intent.action.PICK" /> 250 * <category android:value="android.intent.category.DEFAULT" /> 251 * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 252 * </intent-filter> 253 * <intent-filter> 254 * <action android:value="android.intent.action.GET_CONTENT" /> 255 * <category android:value="android.intent.category.DEFAULT" /> 256 * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 257 * </intent-filter> 258 * </activity> 259 * 260 * <activity class=".NoteEditor" android:label="@string/title_note"> 261 * <intent-filter android:label="@string/resolve_edit"> 262 * <action android:value="android.intent.action.VIEW" /> 263 * <action android:value="android.intent.action.EDIT" /> 264 * <category android:value="android.intent.category.DEFAULT" /> 265 * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 266 * </intent-filter> 267 * 268 * <intent-filter> 269 * <action android:value="android.intent.action.INSERT" /> 270 * <category android:value="android.intent.category.DEFAULT" /> 271 * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 272 * </intent-filter> 273 * 274 * </activity> 275 * 276 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 277 * android:theme="@android:style/Theme.Dialog"> 278 * <intent-filter android:label="@string/resolve_title"> 279 * <action android:value="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 280 * <category android:value="android.intent.category.DEFAULT" /> 281 * <category android:value="android.intent.category.ALTERNATIVE" /> 282 * <category android:value="android.intent.category.SELECTED_ALTERNATIVE" /> 283 * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 284 * </intent-filter> 285 * </activity> 286 * 287 * </application> 288 * </manifest></pre> 289 * 290 * <p>The first activity, 291 * <code>com.android.notepad.NotesList</code>, serves as our main 292 * entry into the app. It can do three things as described by its three intent 293 * templates: 294 * <ol> 295 * <li><pre> 296 * <intent-filter> 297 * <action android:value="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 298 * <category android:value="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 299 * </intent-filter></pre> 300 * <p>This provides a top-level entry into the NotePad application: the standard 301 * MAIN action is a main entry point (not requiring any other information in 302 * the Intent), and the LAUNCHER category says that this entry point should be 303 * listed in the application launcher.</p> 304 * <li><pre> 305 * <intent-filter> 306 * <action android:value="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 307 * <action android:value="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 308 * <action android:value="{@link #ACTION_PICK android.intent.action.PICK}" /> 309 * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 310 * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 311 * </intent-filter></pre> 312 * <p>This declares the things that the activity can do on a directory of 313 * notes. The type being supported is given with the <type> tag, where 314 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 315 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 316 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 317 * The activity allows the user to view or edit the directory of data (via 318 * the VIEW and EDIT actions), or to pick a particular note and return it 319 * to the caller (via the PICK action). Note also the DEFAULT category 320 * supplied here: this is <em>required</em> for the 321 * {@link Context#startActivity Context.startActivity} method to resolve your 322 * activity when its component name is not explicitly specified.</p> 323 * <li><pre> 324 * <intent-filter> 325 * <action android:value="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 326 * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 327 * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 328 * </intent-filter></pre> 329 * <p>This filter describes the ability return to the caller a note selected by 330 * the user without needing to know where it came from. The data type 331 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 332 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 333 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 334 * The GET_CONTENT action is similar to the PICK action, where the activity 335 * will return to its caller a piece of data selected by the user. Here, 336 * however, the caller specifies the type of data they desire instead of 337 * the type of data the user will be picking from.</p> 338 * </ol> 339 * 340 * <p>Given these capabilities, the following intents will resolve to the 341 * NotesList activity:</p> 342 * 343 * <ul> 344 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 345 * activities that can be used as top-level entry points into an 346 * application.</p> 347 * <li> <p><b>{ action=android.app.action.MAIN, 348 * category=android.app.category.LAUNCHER }</b> is the actual intent 349 * used by the Launcher to populate its top-level list.</p> 350 * <li> <p><b>{ action=android.app.action.VIEW 351 * data=content://com.google.provider.NotePad/notes }</b> 352 * displays a list of all the notes under 353 * "content://com.google.provider.NotePad/notes", which 354 * the user can browse through and see the details on.</p> 355 * <li> <p><b>{ action=android.app.action.PICK 356 * data=content://com.google.provider.NotePad/notes }</b> 357 * provides a list of the notes under 358 * "content://com.google.provider.NotePad/notes", from which 359 * the user can pick a note whose data URL is returned back to the caller.</p> 360 * <li> <p><b>{ action=android.app.action.GET_CONTENT 361 * type=vnd.android.cursor.item/vnd.google.note }</b> 362 * is similar to the pick action, but allows the caller to specify the 363 * kind of data they want back so that the system can find the appropriate 364 * activity to pick something of that data type.</p> 365 * </ul> 366 * 367 * <p>The second activity, 368 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 369 * note entry and allows them to edit it. It can do two things as described 370 * by its two intent templates: 371 * <ol> 372 * <li><pre> 373 * <intent-filter android:label="@string/resolve_edit"> 374 * <action android:value="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 375 * <action android:value="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 376 * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 377 * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 378 * </intent-filter></pre> 379 * <p>The first, primary, purpose of this activity is to let the user interact 380 * with a single note, as decribed by the MIME type 381 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 382 * either VIEW a note or allow the user to EDIT it. Again we support the 383 * DEFAULT category to allow the activity to be launched without explicitly 384 * specifying its component.</p> 385 * <li><pre> 386 * <intent-filter> 387 * <action android:value="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 388 * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 389 * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 390 * </intent-filter></pre> 391 * <p>The secondary use of this activity is to insert a new note entry into 392 * an existing directory of notes. This is used when the user creates a new 393 * note: the INSERT action is executed on the directory of notes, causing 394 * this activity to run and have the user create the new note data which 395 * it then adds to the content provider.</p> 396 * </ol> 397 * 398 * <p>Given these capabilities, the following intents will resolve to the 399 * NoteEditor activity:</p> 400 * 401 * <ul> 402 * <li> <p><b>{ action=android.app.action.VIEW 403 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 404 * shows the user the content of note <var>{ID}</var>.</p> 405 * <li> <p><b>{ action=android.app.action.EDIT 406 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 407 * allows the user to edit the content of note <var>{ID}</var>.</p> 408 * <li> <p><b>{ action=android.app.action.INSERT 409 * data=content://com.google.provider.NotePad/notes }</b> 410 * creates a new, empty note in the notes list at 411 * "content://com.google.provider.NotePad/notes" 412 * and allows the user to edit it. If they keep their changes, the URI 413 * of the newly created note is returned to the caller.</p> 414 * </ul> 415 * 416 * <p>The last activity, 417 * <code>com.android.notepad.TitleEditor</code>, allows the user to 418 * edit the title of a note. This could be implemented as a class that the 419 * application directly invokes (by explicitly setting its component in 420 * the Intent), but here we show a way you can publish alternative 421 * operations on existing data:</p> 422 * 423 * <pre> 424 * <intent-filter android:label="@string/resolve_title"> 425 * <action android:value="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 426 * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 427 * <category android:value="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 428 * <category android:value="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 429 * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 430 * </intent-filter></pre> 431 * 432 * <p>In the single intent template here, we 433 * have created our own private action called 434 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 435 * edit the title of a note. It must be invoked on a specific note 436 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 437 * view and edit actions, but here displays and edits the title contained 438 * in the note data. 439 * 440 * <p>In addition to supporting the default category as usual, our title editor 441 * also supports two other standard categories: ALTERNATIVE and 442 * SELECTED_ALTERNATIVE.
