Integrating Unity and Eclipse

Hi!

I'm not familiar with eclipse, but it sounds very interesting!
How do i have to think about a "simple workflow" integrating a unity project within eclipse or whats the benefit of it ?

• Creating 3D Content or more scenes in Unity
• Making the Userinterface in Eclipse
• Load the Unity3D Content by a "Press-to-Play-Button" made in Eclipse?
• Publish the project as a android / ios app from Eclipse?

Greetings
Robert

 

Gays , I am very excited .
eclipse problem that bothers me a long time.
I have come across most of your questions,
I have try Unity3D3.5 、Unity3D3.4.2,Unity3D3.4.1,but only 3.4.1 can publish with Eclipse ；） Just try with 3.4.1 .
Hope Official look...

 

You need change the name of StagingArea

 

Hey guys, I've been trying to do this all day and the app immediately crashes on me. I've tried to build both an existing project and a bare bones project and get the same results for both.

Is this a 3.5 issue, or am I possibly doing something wrong?

Thanks,
Nathan

 

Try with 3.4.1

 

Hello,

I'm getting this error:

Code (csharp):

1.  
2. D/Unity(3776): [SHA1] da39a3ee5e6b4b0d3255bfef95601890afd80709          0 bytes ~ assets/libs/armeabi-v7a/libunity.so

9.  

Using unity 3.5
Runs fine on iOS and web but doesn't work on android in eclipse. Anyone know what this error means?

 

After some testing I can confirm that 3.5 doesn't work with eclipse and 3.4.1 does.

 

I was able to skip the whole integrate into Eclipse process that I thought I needed to do and instead went the plugin route instead and it works great... much simpler workflow too

I'm sure there are some cases where you need to use the Intergrate into Eclipse method, but you can implement your own UnityPlayerActivty and your own Application class via plugin.

 

Hi,

I just posted about this in another thread but, 3.5 is broken (Eclipse integration, not the actual Android application).

I was searching last week and found a paste bin entry for Unity 3.5.1RC1 that stated Eclipse Android crashing bug was fixed. So I guess we have to hold on for the 3.5.1 update to get our Eclipse dev back.

Another note; I too ended up going the plugin route and just doing the build and run for testing, works for now! Logcat is still hooked up and really the only part that is missing is break point support.

"I'm sure there are some cases where you need to use the Intergrate into Eclipse method, but you can implement your own UnityPlayerActivty and your own Application class via plugin. "

This is so true, remember folks, dropping in a modified android manifest xml file in the Plugins folder is completely legal! What I mean is, if you want a custom Activity impl, just include it in the jar in the Plugins folder and change the MAIN LAUNCHER activity to that package and class name

PS I am also including .so files in that Plugin folder as well, Unity knows exactly what to do with it to get the shared library loaded at runtime.

In my case, I solved the problem by repacking apk which eclipse produces.
> zipalign -v 4 EclipseProduced.apk RenewPackage.apk
you can find zipalign program in the android SDK tools directory.

Thank You!!! It worked for me!!!

 

At first try, it didn't work for me (don't know why), but now it is working.

Thanks!

Gus

 

It worked for me too ! Thanks !

 

Hi!

I have problems again. I have downloaded and installed unity 3.5.1 version, and now I am experiencing the same problem: It doesn´t work. I have tried with zipalign, but still doesn`t work.

 

Hi, i spend a lot of time now... and tried to compile Unity with eclipse like in the video in this post...in my case it only works with the android SDK 2.3.3! I tryed many time with new android version 4.0.3 and it did not worked! But anyway now it works fine..also with Unity 3.5.2f and the classes.jar file from this version.

 

OK now it runs also with 4.0.3.... i think the Android Dependencies are not needed! Maybe this was my fault when first try!

 

There are some updated steps to follow at http://forum.unity3d.com/threads/98315-Using-Unity-Android-In-a-Sub-View. These were tested with Unity 3.5.2.

 

Dendrophile - did you test the other thread to work with 3.5.2?

 

I have tried the above post and my package compiles, But I cannot start the application because i get a runtime error unable to instantiate activity caused by Class not found exception that points to the class .MainActivity which is what the new activity that was created with the UnityJava project

 

@ahmed_ameen21: did you found the solution?
i am facing the same problem as you.

 

maybe my video tutorials will help -> http://www.youtube.com/watch?v=zxn2CuQszvw

 

Can anybody guide me to setup a two way communication channel between the integrated unity part and the eclipse part....I need to send a string from unity to android and some integers from eclipse to unity. Any ideas or links would help. I've done the integration part for iPhone and Unity where I could send messages between the two through playerprefs of unity and NsUserDefaults of Xcode. Is there a similar setup for eclipse and Unity?

 

I use Unity 3.5.5f3 and Android 2.3.3. No zipaling required.

I've followed RoflHarris's tutorial and first problem was "The container 'Library Projects' references non existing library 'D:\Projects\Android\UnityLibrary\bin\unitylibrary.jar'". When I try to Build UnityLibrary I got "AndroidManifest.xml file is missing" error. I've copied that file from StagingArea folder.

Second problem was "android:configChanges" section some Android 4 specific features. So I removed some of them and it became like

Code (csharp):

1. android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout"

Third problem was "Couldn't load mono: findLibrary returned null". I've copied StagingArea\libs folder to UnityApplication\libs folder.

Fourth problem was ".UnityEclipse.UnityApplicationActivity (server)' ~ Consumer closed input channel or an error occurred. events=0x8". I'have modified AndroidManifest.xml file in UnityApplication so that activity section has

Code (csharp):

1. android:configChanges="orientation"

feature.

I have just tried to implement a Cube in Eclipse. I don't know if it will work for QCAR, Vuforia, AdMob, Mobiclix or any other libraries and scripts.

 

I've created a guide in my blog http://turkertunali.blogspot.com/

 

I saw this in the Unity Asset Store. Pretty awesome. Has anyone tried it and does it work well for exporting to eclipse?

http://u3d.as/content/appjigger-studios/unity2eclipse/3jT

 

Hello everyone!

I've been testing out Unity for the past couple of weeks and using the instructions to integrate Unity with Android Eclipse Project ( Linusmartensson ). Everything goes well, the app starts on my device (ASUS Tablet TF101), no errors in Eclipse project, the splash image starts on the device. However, suddenly the app is closed without showing me the unity environment.

I've been repeating the process of integrating Unity + Eclipse almost 20 times, i really don't know why doesn't work.
So the problem is basically: Why the app closes down suddenly without errors in eclipse?

It is not problem of the device or incompatibility with unity, because i tried to start this apk made by unity and it works, the problem is when I extend from UnityPlayerActivity.

Please help! Thank you very much

Jud

 

when i integrate unity and eclipse, the sound plays rapidly... someone know the solution?

sorry my english

 

I have exactly the same issue. Anyone knows how to fix this?



I followed the guide, but do we need the "android dependencies" ?



The container 'Android Dependencies' references non existing library 'C:\Users\BulleTTime\Desktop\KEP\app\testapp\Temp\StagingArea\bin\com.unity3d.player.unityplayerproxyactivity.jar'

 

This worked for me to!


Is there any way to automaticly do this when i run from eclipse?

Thanks

 

Hi i am also getting the same problem . can you please tellme how to clear it if you have already done it.

 

I have both these files in my unityJava project in eclipse but still its not working Please tell me

 

It turns out the way that ADT 17 handles .jar files broke this method of integrating Unity into Eclipse, causing various errors. Instead of adding classes.jar to your build path, you should just copy the classes.jar file into the lib directory of your project, and everything should work properly.

 

First of all thanks for reply..

It worked.

I have followed the steps to import unity in eclipse.

Created project from existing code and made it a library.

Created a new project in eclipse, with same package name.

imported classes.jar form unity.

Moved assets from lib to main project.

included the library project.

All is fine.

Now when i am running it on eclipse the class not found error is displayed.

First i created a Mainactivity in main project but got error class com.brownsugar.TestAndroid03102012.Main Activity not found.

Then i copied the android manifest from lib project then also i am getting error com.unity3d.player.unity3dplayerproxyactivity not found.

I have attached the screen shots
Please help me...

 

http://u3d.as/content/appjigger-stud...ty2eclipse/3jT[

I haven't use this myself, but I'm going to try this next week.

 

I did this manually and I get a error:

The file /data/app...../assets/bin/Data/sharedassets0.assets is corrupted! Remove it and launch unity again
[Position out of bounds!]

I also tryed with eclispe2unity plugin with the same error.

Any suggestions? The project runs perfectly by hit build&Run button on Unity. And the method works if I try with an empty project.

Regards

 

Hi All,

It seems that Unity have improved the workflow with Eclipse in 4.0.0f7 (same results in 4.0.0bx), now all you have to do is to check Create Eclipse Project from the Build Settings dialogue and export.

That's great as it removes the ugly process of creating lib projects and all that messy stuff. The export creates one Eclipse project that you can open in Eclipse and run without much ado.

One problem I came across is that after I export to Eclipse and work in Eclipse to add my Java code and what not, things work fine but more often than not, when I quit Unity it tends to wipe out the Eclipse project I exported earlier.

Now I think that's a bug, Unity have remove all Eclipse integration documents from their site and we are left with a very promising but half working integration workflow.

My question is, did anyone out here come across the same behaviour? And what did you do to mitigate the problem?

Cheers
Paul

 

netlander, when i close Unity4 the project stays.

Problem i'm having is trying to create a simple plugin using AndroidJavaObject and AndroidJavaClass, i import the exported project within Eclipse, create a new class within 'src':

Code (csharp):

1.  
2. package com.ant.mobile;
3. import android.util.Log;
4.  
5. public class JAUnity {
6.     public static JAUnity m_instance;
7.     public static JAUnity instance() {
8.  
9.         if(m_instance == null) {
10.             m_instance = new JAUnity();
11.         }
12.         return m_instance;
13.     }
14.  
15.     private JAUnity() { }
16.  
17.     public void doit() {
18.         Log.w("JAUnity", "doit");
19.     }
20. }
21.  
22.  

Then have my C# call across to it:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using System.IO;
5.  
6. public class CallJava : MonoBehaviour {
7.     public static AndroidJavaObject _ajo;
8.     public static AndroidJavaClass _ajc;
9.    
10.     static CallJava() {
11.         if(Application.platform != RuntimePlatform.Android) return;
12.     }
13.    
14.     void OnGUI() {
15.         if(GUI.Button(new Rect(Screen.width/2, 85, 200, 85), "doit")) {
16.             using(_ajc = new AndroidJavaClass("com.ant.mobile.JAUnity"));
17.             _ajo = _ajc.CallStatic<AndroidJavaObject>("instance");
18.             _ajo.Call("doit");
19.         }
20.     }
21. }
22.  

It all just dies, i wonder if its done a new way in 4.x?

 

@ant001. Indeed, need to describe your problem in more detail. Do you get an exception in logcat? What does it say?

@Erique BTW, I am still getting this intermittent and weird problem of Unity 4 closing the previously exported eclipse project. In fact I've established that Unity does not delete the project but it changes its folder into this archived file of sorts (without an extension but can be opened with 7zip). The problem is intermittent and happens sometimes when closing unity and at other time when opening and sometimes it leaves it alone.

 

All works in Unity4 with the export project magic. I removed the using(...) around AndroidJavaClass.
Now i'm looking return an image from android to Unity so I can use it as a texture.

 

Hey can you help me?
I export my project to eclipse with unity3d 4 and after I import to eclipse but:
where are my c# class... in java?
it's my first time I use eclipse I always used netbeans for java so I really can't find.


if I run it work but there is a way to built in a eclipse player instead my android device.

thank you a lot

How can i solve this problem? Any idea?

 

Hi! First let me thank you for the complete guide! But I've got some problems with the .jar included in the Temp/StagingArea that ain't being recognized by the Java Project. It's correct to include them manually? May I include them as Jar or as External jar? Thanks in advance!

 

Hi.Add as external jar.

 

Hello i've tried getting this working and feel i am getting so close. At first there was tons of errors and emulators not working.

Now emulator building is smooth and fast and I can launch my app on the emulator with no errors in console or logcat.

My only problem now is the "hello world" activity seems to take over if i add activity to the project of which my unity project is the library.
If i add no activity to the project then the app quits at start up. i am pretty certain my issue is i am not setting up my unity project properly so that it will always launch at start up as the main activity.

How is this bit done? I am pretty sure it is I have to add a bit of specialized code to the MainActivity.xml or do I have this all wrong?? ....I've looked around but can't seem to find any info on it?

Sorry if these questions sound noobish... I haven't used eclipse before these attempts. Any help is much appreciated!

this is the logcat feed from when I try to click open my app in the emulator:

emulator closes immediately with message: "Sorry! The application PIXELCAT (process.com.pixelCat.pixelCatFree) has stopped unexpectedly. Please try again. (Force close)"
