## Constants

### PATTERN_ADVANCED_GLOB

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final int PATTERN_ADVANCED_GLOB
```

Pattern type: the given pattern is interpreted with a regular expression-like syntax for matching against the string it is tested against. Supported tokens include dot (`.`) and sets (`[...]`) with full support for character ranges and the not (`^`) modifier. Supported modifiers include star (`*`) for zero-or-more, plus (`+`) for one-or-more and full range (`{...}`) support. This is a simple evaluation implementation in which matching is done against the pattern in real time with no backtracking support.

<br />

Constant Value: 3 (0x00000003)

### PATTERN_LITERAL

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final int PATTERN_LITERAL
```

Pattern type: the given pattern must exactly match the string it is tested against.

<br />

Constant Value: 0 (0x00000000)

### PATTERN_PREFIX

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final int PATTERN_PREFIX
```

Pattern type: the given pattern must match the beginning of the string it is tested against.

<br />

Constant Value: 1 (0x00000001)

### PATTERN_SIMPLE_GLOB

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final int PATTERN_SIMPLE_GLOB
```

Pattern type: the given pattern is interpreted with a simple glob syntax for matching against the string it is tested against. In this syntax, you can use the '\*' character to match against zero or more occurrences of the character immediately before. If the character before it is '.' it will match any character. The character '\\' can be used as an escape. This essentially provides only the '\*' wildcard part of a normal regexp.

<br />

Constant Value: 2 (0x00000002)

### PATTERN_SUFFIX

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final int PATTERN_SUFFIX
```

Pattern type: the given pattern must match the end of the string it is tested against.

<br />

Constant Value: 4 (0x00000004)
