Unable to Initialize Unity Engine — Cookie Run Kingdom Error Fix

Home » Guides » Unable to Initialize Unity Engine – Cookie Run Kingdom Error Fix

Cookie Run Kingdom is one of the more popular mobile games of its type. A building game with some role-playing elements and powerful Cookie Heroes. This combination has made it a worldwide hit. Naturally, whenever an issue occurs in one of these online games, it impacts a large number of players. The latest problem that has recently cropped up is the “Unable to Initialize Unity Engine” error that many players are getting when they try to run the game. If you have been affected by this, then our Unable to Initialize Unity Engine – Cookie Run Kingdom Error Fix guide is here to provide you with a couple of solutions that can resolve this problem.

How to Fix the Unable to Initialize Unity Engine Error in Cookie Run Kingdom

The Unity engine is a very famous game engine that is used to power many video games, and is particularly used in mobile game development for both Android and iOS devices. This error could be down to some change in Unity itself. But there’s also the chance that Cookie Run Kingdom developer Devsisters have messed something up on their end and that a fix for this problem is incoming. Whatever the case may be, there are a couple of things you can try out in the meantime until this error gets resolved on the developers’ side.

The first method that you can try is to attempt to run the game from your app drawer. Several users have reported that the game refuses to run if they launch it from the icon shortcut on their phone home screen, but that it does work when they launch it from their phone’s app section. The second method is to do a hard restart on your phone. When it restarts, the phone should update all the apps, and, hopefully, the problem should be resolved. The third solution is to turn your WIFI off and on before you get the error (thanks Carly). So far, these are the only possible solutions which seem to work. If you know of any other methods which can be used to fix this, don’t be shy about telling us in the comments below.

Troubleshooting Android development

“No Platforms Found” error:

1. Uninstall the current Android SDK and make sure that you don’t have more than one copy of it.
2. Update Java with a stable version. Bear in mind the latest version shouldn’t have conflicts, but users have experienced problems in the past.
3. Download a fresh copy of the latest ADT Bundle and install it following the instructions. This should configure the development tools correctly: http://developer.android.com/sdk/index.html
4. Configure Unity with the installed Android SDK.

Unity fails to install your application to your device

1. Verify that your computer can actually see and communicate with the device. See the Publishing Builds page for further details.
2. Check the error message in the Unity console. This will often help diagnose the problem.

If you get an error saying “Unable to install APK, protocol failure” during a build then this indicates that the device is connected to a low-power USB port (perhaps a port on a keyboard or other peripheral). If this happens, try connecting the device to a USB port on the computer itself.

1. Ensure that you are not trying to use NativeActivity with devices that do not support it.
2. Try removing any native plugins you have.
3. Try disabling stripping.
4. Use adb logcat to get the crash report from your device.

Building DEX Failed

This is an error which will produce a message similar to the following:-

This is usually caused by having the wrong version of Java installed on your machine. Updating your Java installation to the latest version will generally solve this issue.

The game crashes after a couple of seconds when playing video

Make sure Settings->Developer Options->Don’t keep activities isn’t enabled on the phone. The video player is its own activity and therefore the regular game activity will be destroyed if the video player is activated.

My game quits when I press the sleep button

Change the activity tag in the AndroidManifest.xml to contain android:configChanges tag as described here.

An example activity tag might look something like this:-

Troubleshooting Android development

While developing for Android using Unity, you could encounter a number of issues. Problems are often related to plug-ins A set of code created outside of Unity that creates functionality in Unity. There are two kinds of plug-ins you can use in Unity: Managed plug-ins (managed .NET assemblies created with tools like Visual Studio) and Native plug-ins (platform-specific native code libraries). More info
See in Glossary or incorrect Project settings A broad collection of settings which allow you to configure how Physics, Audio, Networking, Graphics, Input and many other areas of your Project behave. More info
See in Glossary . This section outlines the most common scenarios and relavant troubleshooting advice.

Remove any native plug-ins A platform-specific native code library that is created outside of Unity for use in Unity. Allows you can access features like OS calls and third-party code libraries that would otherwise not be available to Unity. More info
See in Glossary you have.

Use adb logcat to get the crash report from your device. Consult the official Android Developer Logcat Command-Line Tool documentation for more information.

The game crashes after a couple of seconds when playing video

Ensure Settings > Developer Options > Don’t keep activities isn’t enabled on the device.

The video player is its own activity, and therefore regular game activity will be destroyed if the video player is activated.

No Android device found

If Unity cannot find an Android device connected to the system, check the following:

Make sure that your device is actually connected to your computer — check the USB cable and the sockets.

Make sure that your device has USB Debugging enabled in the Developer options. For more details, refer to the Android SDK/NDK Setup page.

Run the adb devices command from the platform-tools directory of your Android SDK installation and check the output.

If the output list is empty and you are using Windows, you may need to install the driver for ADB An Android Debug Bridge (ADB). You can use an ADB to deploy an Android package (APK) manually after building. More info
See in Glossary devices. For more details, refer to the Android SDK/NDK Setup documentation.

If the list contains entries with the unauthorized label, you may need to authorize your computer on your device and give it permission to debug it. Check the device’s screen for the corresponding dialog.

If the list contains your device with the device label, build your Project in Unity again.

Failed to re-package resources

This error occurs when the Android Asset Any media or data that can be used in your game or Project. An asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image. You can also create some asset types in Unity, such as an Animator Controller, an Audio Mixer or a Render Texture. More info
See in Glossary Packaging Tool (AAPT) fails. AAPT is used to build the intermediate Asset packages A collection of files and data from Unity Projects, or elements of Projects, which are compressed and stored in one file, similar to Zip files. Packages are a handy way of sharing and re-using Unity Projects and collections of assets. More info
See in Glossary during Android build. This issue is most often caused by missing resources or duplicate resources in your Android plug-ins.

Check the console message for more details — it should contain the IDs of the resources that are missing or duplicates. Fix the error in your plug-ins by either adding the missing resources/settings or removing the duplicate plug-ins.

Unable to merge Android manifests

The most likely cause for this issue is that one of your plug-ins has a manifest that is incompatible with the main Unity manifest.

Check the console message for more details on which attributes are conflicting, and fix the manifests accordingly.

See the Android Manifest documentation for more details on Android manifests.

Unable to convert classes into DEX format

The most likely cause for this issue is that you have a Java plug-in added twice. This results in duplicate classes when Unity tries to build a DEX (Dalvik Executable Format) file from all the compiled Java plug-ins. Check the console output for the list of duplicate entries, and fix the plug-ins.

If your console messages says “Too many references”, it means that the number of fields and methods exceeded the DEX limit of 64k. This usually happens when the number of plug-ins or plug-in resources is too high. Due to the way the references are generated, the limit could be hit with just a couple of large plug-ins.

There are several ways to handle this issue. One of these is by stripping the plug-ins. However, the quickest way to fix it is to switch to the Gradle build system, or export the Project and build it in Android Studio.

Unable to install APK to device

This error can be caused by:

Installing to an incompatible device.

Installing to a device running a version of Android lower than the Minimum API Level in your Player settings.

Check the console for the actual error code and output.
