## Public methods

### additionalParameters

```
abstract fun additionalParameters(params: String): Unit
```

Adds additional parameters to be passed to`aapt`.  

### additionalParameters

```
abstract fun additionalParameters(vararg params: String): Unit
```

Adds additional parameters to be passed to`aapt`.  

### noCompress

```
abstract fun noCompress(noCompress: String): Unit
```

Adds extensions of files that will not be stored compressed in the APK.

Equivalent of the -0 flag. See`aapt --help`  

### noCompress

```
abstract fun noCompress(vararg noCompress: String): Unit
```

Adds extensions of files that will not be stored compressed in the APK.

Equivalent of the -0 flag. See`aapt --help`

## Properties

### additionalParameters

```
abstract val additionalParameters: MutableList<String>
```

List of additional parameters to pass to`aapt`.  

### failOnMissingConfigEntry

```
abstract var failOnMissingConfigEntry: Boolean
```

Forces aapt to return an error if it fails to find an entry for a configuration.

See`aapt --help`  

### ignoreAssetsPattern

```
abstract var ignoreAssetsPattern: String?
```

Pattern describing assets to be ignore.

See`aapt --help`  

### namespaced

```
abstract var namespaced: Boolean
```

Indicates whether the resources in this sub-project are fully namespaced.

This property is incubating and may change in a future release.  

### noCompress

```
abstract val noCompress: MutableCollection<String>
```

Extensions of files that will not be stored compressed in the APK. Adding an empty extension, i.e., setting`noCompress ''`will trivially disable compression for all files.

Equivalent of the -0 flag. See`aapt --help`
