Learn how to reduce APK size when integrating the Zoom SDK by filtering CPU architectures and disabling native library extraction.

Reduce APK size

Since our SDK contains NDK code, it must be built individually for all
CPU architectures to satisfy each ABI type. As a result, adding the SDK
to your project may have the unintended consequence of drastically
increasing your APK size. Here are a couple of steps you can take to
mitigate a significant portion of this increase.

## Applying ABI filters

If you know that you will not need to support certain CPU types,
filter them out in your app's `build.gradle` file. To do so, add
this block within `defaultConfig`.

```groovy
ndk {
  abiFilters 'x86', 'x86_64' // Do not build for x86 & x86_64 CPUs
}
```

Doing this for all CPU architectures you do not wish to support can
greatly reduce the size of the SDK's files.

## Do not extract native libraries

Another step you can take to reduce the size of the SDK is to set the
following attribute in your `AndroidManifest.xml`.

```xml
<application
  extractNativeLibs='false'
```

See [Avoid extracting native
libraries](https://developer.android.com/topic/performance/reduce-apk-size#extract-false)
in the Android Developers documentation for details.
