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