Mockoon for Android. More details can be found in this blog post.

This is the android port of mocking server Mockoon. Export your mockoon environment and then run it in android.

This library will add around 60MB to your app, so you might want to create a dedicated variant.

        mock {
            initWith debug
            applicationIdSuffix ".mock"
        }

Add this dependency in your app layer's build.gradle.

    mockImplementation 'np.com.susanthapa:mockoon-android:0.6.1'

Use reflection to start mockoon as gradle won't be able to resolve the dependency for all variants. Create a helper function to start the server like this.

    private fun startMock(mockPath: String? = null, uri: Uri? = null) {
        if (BuildConfig.BUILD_TYPE == "mock") {
            // use reflection as we don't want to include this in other build variants
            try {
                val mockClass = Class.forName("np.com.susanthapa.mockoon_android.MockoonAndroid")
                val constructor = mockClass.getConstructor(String::class.java, Uri::class.java)
                val mock = constructor.newInstance(mockPath, uri)
                val startMethod = mockClass.getMethod("startMock", Context::class.java)
                startMethod.invoke(mock, this)

            } catch (e: Exception) {
                e.printStackTrace()
            }
        }
    }

The start function accepts two arguments, atleast one argument is required. The first argument mockPath can be used if you have location of the mock file. This is mostly useful when you want to bundle the environment with your app as assets. You can use the second argument uri if you want to load the environment from file systems.
