Unable to move from android to iOS

From the screenshot given by you I gather that you are trying to push data from Android to iPhone.

Do it other way around

Pull data from Android to iPhone as shown below

Move from Android to iPhone, iPad, or iPod touch

Ready to transfer to iOS? Download the Move to iOS app to get help switching from your Android device to your new iPhone, iPad, or iPod touch.

Get Move to iOS from Google Play

Before you begin

• On your Android device, make sure that Wi-Fi is turned on. 
• Plug your new iOS device and your Android device into power.
• Make sure that the content you're moving, including what's on your external Micro SD card, will fit on your new iOS device
• If you want to transfer your Chrome bookmarks, update to the latest version of Chrome on your Android device.

Tap Move Data from Android

While you set up your new iOS device, look for the Apps & Data screen. Then tap Move Data from Android. (If you already finished setup, you need to  erase your iOS device and start over. If you don't want to erase, just transfer your content manually.)

Open the Move to iOS app

On your Android device, open the Move to iOS app and tap Continue. Read the terms and conditions that appear. To continue, tap Agree, then tap Next in the top-right corner of the Find Your Code screen.

Wait for a code

On your iOS device, tap Continue on the screen called Move from Android. Then wait for a ten-digit or six-digit code to appear. If your Android device shows an alert that you have a weak Internet connection, you can ignore the alert.

Use the code

Enter the code on your Android device. Then wait for the Transfer Data screen to appear. 

Choose your content and wait

On your Android device, select the content that you want to transfer and tap Next. Then — even if your Android indicates that the process is complete — leave both devices alone until the loading bar that appears on your iOS device finishes. The whole transfer can take a while, depending on how much content you're moving.

Here's what gets transferred: contacts, message history, camera photos and videos, web bookmarks, mail accounts, and calendars. If they're available on both Google Play and the App Store, some of your free apps will also transfer. After the transfer completes, you can download any free apps that were matched from the App Store.

Set up your iOS device

After the loading bar finishes on your iOS device, tap Done on your Android device. Then tap Continue on your iOS device and follow the onscreen steps to finish setup for your iOS device.

Finish up

Make sure that all of your content transferred. Music, Books, and PDFs need to be moved over manually.

Need to get the apps that were on your Android device? Go to the App Store on your iOS device to download them.

As I can tell from a screenshot, you are not connected to Wi-Fi. And you should be.

1. 1. Restart both iOS and Android devices.
2. Check the network connection on both devices.
3. Check Android device network settings and turn off the option for “Smart network switch”, or Connections Optimizer.
4. Set your Android into Airplane Mode, which can make sure that Wi-Fi will not be kicked off during the transferring.
5. Switch off your Wi-Fi or switch between WiFi and mobile data on your Android, which is helpful to solve “Move to iOS could not communicate with device” issue.
