## Public functions
### addManifestPlaceholders
```
@Incubating
fun addManifestPlaceholders(manifestPlaceholders: Map?): Unit
```
Adds manifest placeholders.

### buildConfigField
```
@Incubating
fun buildConfigField(type: String?, name: String?, value: String?): Unit
```
Adds a new field to the generated BuildConfig class.
The field is generated as:` = ;`
This means each of these must have valid Java content. If the type is a String, then the value should include quotes.
| Parameters ||
|----------------------------------------------------------------------------------------------|------------------------|
| `type: `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`?` | the type of the field |
| `name: `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`?` | the name of the field |
| `value: `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`?` | the value of the field |
### externalNativeBuild
```
@Incubating
fun externalNativeBuild(action: (@ExtensionFunctionType ExternalNativeBuildOptions.() -> Unit)?): Unit
```
Encapsulates per-variant CMake and ndk-build configurations for your external native build.
To learn more, see[Add C and C++ Code to Your Project](http://developer.android.com/studio/projects/add-native-code.html#).
### javaCompileOptions
```
fun javaCompileOptions(action: (@ExtensionFunctionType JavaCompileOptions.() -> Unit)?): Unit
```
Options for configuring Java compilation.
### ndk
```
@Incubating
fun ndk(action: (@ExtensionFunctionType Ndk.() -> Unit)?): Unit
```
Encapsulates per-variant configurations for the NDK, such as ABI filters.
### proguardFile
```
@Incubating
fun proguardFile(proguardFile: Any?): Any
```
Adds a new ProGuard configuration file.
`proguardFile getDefaultProguardFile('proguard-android.txt')`
There are two ProGuard rules files that ship with the Android plugin and are used by default:
- proguard-android.txt
- proguard-android-optimize.txt
`proguard-android-optimize.txt`is identical to`proguard-android.txt`, except with optimizations enabled. You can use getDefaultProguardFile(String) to return the full path of the files.
This method has a return value for legacy reasons.
### proguardFiles
```
@Incubating
fun proguardFiles(vararg files: Any?): Any
```
Adds new ProGuard configuration files.
There are two ProGuard rules files that ship with the Android plugin and are used by default:
- proguard-android.txt
- proguard-android-optimize.txt
`proguard-android-optimize.txt`is identical to`proguard-android.txt`, except with optimizations enabled. You can use getDefaultProguardFile(String) to return the full path of the files.
This method has a return value for legacy reasons.
### resValue
```
@Incubating
fun resValue(type: String?, name: String?, value: String?): Unit
```
Adds a new generated resource.
This is equivalent to specifying a resource in res/values.
See[Resource Types](http://developer.android.com/guide/topics/resources/available-resources.html).
| Parameters ||
|----------------------------------------------------------------------------------------------|---------------------------|
| `type: `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`?` | the type of the resource |
| `name: `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`?` | the name of the resource |
| `value: `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`?` | the value of the resource |
### setManifestPlaceholders
```
@Incubating
fun [setManifestPlaceholders](https://developer.android.com/reference/tools/gradle-api/7.2/com/android/build/api/dsl/VariantDimension#setManifestPlaceholders(kotlin.collections.Map))(manifestPlaceholders: Map?): Void?
```
| **This function is deprecated.**
Use manifestPlaceholders property instead
### setProguardFiles
```
@Incubating
fun setProguardFiles(proguardFileIterable: Iterable<*>?): Any
```
Replaces the ProGuard configuration files.
This method has a return value for legacy reasons.
### shaders
```
@Incubating
fun shaders(action: (@ExtensionFunctionType Shaders.() -> Unit)?): Unit
```
Configure the shader compiler options.
### testProguardFile
```
@Incubating
fun testProguardFile(proguardFile: Any?): Any
```
Adds a proguard rule file to be used when processing test code.
Test code needs to be processed to apply the same obfuscation as was done to main code.
This method has a return value for legacy reasons.
### testProguardFiles
```
@Incubating
fun testProguardFiles(vararg proguardFiles: Any?): Any
```
Adds proguard rule files to be used when processing test code.
Test code needs to be processed to apply the same obfuscation as was done to main code.
This method has a return value for legacy reasons.
## Public properties
### externalNativeBuild
```
val externalNativeBuild: ExternalNativeBuildOptions
```
Encapsulates per-variant CMake and ndk-build configurations for your external native build.
To learn more, see[Add C and C++ Code to Your Project](http://developer.android.com/studio/projects/add-native-code.html#).
### javaCompileOptions
