| 39 | * Structured description of Intent values to be matched. An IntentFilter can |
| 40 | * match against actions, categories, and data (either via its type, scheme, |
| 41 | * and/or path) in an Intent. It also includes a "priority" value which is |
| 42 | * used to order multiple matching filters. |
| 43 | * |
| 44 | * <p>IntentFilter objects are often created in XML as part of a package's |
| 45 | * {@link android.R.styleable#AndroidManifest AndroidManifest.xml} file, |
| 46 | * using {@link android.R.styleable#AndroidManifestIntentFilter intent-filter} |
| 47 | * tags. |
| 48 | * |
| 49 | * <p>There are three Intent characteristics you can filter on: the |
| 50 | * <em>action</em>, <em>data</em>, and <em>categories</em>. For each of these |
| 51 | * characteristics you can provide |
| 52 | * multiple possible matching values (via {@link #addAction}, |
Dianne Hackborn | df1c0bf | 2013-06-12 16:21:38 -0700 | [diff] [blame] | 53 | * {@link #addDataType}, {@link #addDataScheme}, {@link #addDataSchemeSpecificPart}, |
| 54 | * {@link #addDataAuthority}, {@link #addDataPath}, and {@link #addCategory}, respectively). |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 55 | * For actions, the field |
| 56 | * will not be tested if no values have been given (treating it as a wildcard); |
| 57 | * if no data characteristics are specified, however, then the filter will |
| 58 | * only match intents that contain no data. |
| 59 | * |
| 60 | * <p>The data characteristic is |
| 61 | * itself divided into three attributes: type, scheme, authority, and path. |
| 62 | * Any that are |
| 63 | * specified must match the contents of the Intent. If you specify a scheme |
| 64 | * but no type, only Intent that does not have a type (such as mailto:) will |
| 65 | * match; a content: URI will never match because they always have a MIME type |
| 66 | * that is supplied by their content provider. Specifying a type with no scheme |
| 67 | * has somewhat special meaning: it will match either an Intent with no URI |
| 68 | * field, or an Intent with a content: or file: URI. If you specify neither, |
| 69 | * then only an Intent with no data or type will match. To specify an authority, |
| 70 | * you must also specify one or more schemes that it is associated with. |
| 71 | * To specify a path, you also must specify both one or more authorities and |
| 72 | * one or more schemes it is associated with. |

The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 82 | * <p>A match is based on the following rules. Note that |
| 83 | * for an IntentFilter to match an Intent, three conditions must hold: |
| 84 | * the <strong>action</strong> and <strong>category</strong> must match, and |
| 85 | * the data (both the <strong>data type</strong> and |
Dianne Hackborn | 0ea920d | 2013-10-11 09:40:18 -0700 | [diff] [blame] | 86 | * <strong>data scheme+authority+path</strong> if specified) must match |
| 87 | * (see {@link #match(ContentResolver, Intent, boolean, String)} for more details |
| 88 | * on how the data fields match). |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 89 | * |
| 90 | * <p><strong>Action</strong> matches if any of the given values match the |
Dianne Hackborn | a53ee35 | 2013-02-20 12:47:02 -0800 | [diff] [blame] | 91 | * Intent action; if the filter specifies no actions, then it will only match |
| 92 | * Intents that do not contain an action. |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 93 | * |
| 94 | * <p><strong>Data Type</strong> matches if any of the given values match the |
| 95 | * Intent type. The Intent |
| 96 | * type is determined by calling {@link Intent#resolveType}. A wildcard can be |
| 97 | * used for the MIME sub-type, in both the Intent and IntentFilter, so that the |
| 98 | * type "audio/*" will match "audio/mpeg", "audio/aiff", "audio/*", etc. |
