Running on Android Studio

cocos2d-x C++
#1

I’m following http://cocos2d-x.org/docs/installation/Android-Studio/index.html. However when I try to run cpp-tests it comes up with Unfortunately, libcocos2dx has stopped

In logcat, it shows:

I’m using cocos2d-x v3.10, ndk r10e, and android-16 and testing on a virtual emulator.

How do I get this to run properly?

#2

I’m not sure yet. When I wrote that documentation, I tested on hardware with r10c and Android 2.1 while it was still in a beta phase.

#3

The beta phase of what? Android Studio?

Sorry for the late reply, I was busy.

#4

I know the problem is within Android Studio’s emulator as I just tried cpp-tests using MEmu emulator and it worked.

#5

It might be that you are using a x86 emulator but cocos compile is doing only Arm NDK build by default. Either try using Arm emulator or update the .mk files to do x86 NDK builds also.

#6

I tried using an ARM emulator but it still didn’t work.

This is my updated logcat (I missed the beginning when I first posted.):

Here is the same thing. When i try to run , i get this. No matter what i use for run. Real device, virtual device. It doesn’t matter. Just getting Fatal exception something like this.

@teatone This happens because you don’t compile for the architecture you are trying to test on.

Change to APP_ABI := armeabi armeabi-v7a x86 in Application.mk file and recompile.

#10

nothing is changed

@teatone @xxYxx it seems you forgot to compile your code first. Compiling C++ code is currently not supported in Android Studio, you have to use cocos console instead:

cocos compile -p android --android-studio

After executing this command you should be able to run your project from within Android Studio

#12

I did it before posting about my issue. Even I make new project for just compile it properly then try to open with random devices.

#13

I got same problem.
