In order to build the PSPDFKit Flutter wrapper and example project, you need to prepare a couple of dependencies:
- The [latest stable version of Android Studio][https://developer.android.com/studio].
- The [Android NDK][https://developer.android.com/studio/projects/install-ndk].
- An [Android Virtual Device][https://developer.android.com/studio/run/managing-avds.html] or a hardware device.
- The [latest stable version of PSPDFKit for Android][https://pspdfkit.com/guides/android/downloads/].
- The [latest stable version of Flutter][https://flutter.dev/docs/get-started/install].
local.propertiesfile
Upon opening the Flutter example project for the first time inside Android Studio, the IDE will create a new local.properties file which should already contain paths to your local Android SDK installation. You will need to add another property flutter.sdk which points to your local flutter installation. Like this:
sdk.dir=/path/to/your/android/sdk
ndk.dir=/path/to/your/android/sdk/ndk-bundle
flutter.sdk=/path/to/your/flutter/sdkSee the setup instructions in the main README.
Please take a look how to run our example project here.
This project uses Gradle 4.9+ which no longer supports on-demand configuration of projects. It might be that your Android Studio still has configuration on demand enabled, in which case syncing the Gradle files will yield an error like this:
> Failed to apply plugin [id 'com.android.application']
> Configuration on demand is not supported by the current version of the Android Gradle plugin since you are using Gradle version 4.6 or above. Suggestion: disable configuration on demand by setting org.gradle.configureondemand=false in your gradle.properties file or use a Gradle version less than 4.6.
To resolve this, please go to your Android Studio preferences and remove the checkmark at Configure on demand inside Build, Execution, Deployment -> Compiler.
