I found it here and tried it immediately.
I get the following error, but does anyone know the cause?

make: *** [D:/cocos2dProjects/MyGame/proj.android-studio/app/build/intermediates/ndkBuild/debug/obj/local/armeabi-v7a/libcocos2dxinternal.a] Error

I am very sorry for the sentence using the Google translation because it is Japanese and I am not good at English.
Thank you for your consideration.

Android Studio: Build-Run AND Auto Complete?

Is that a full stack trace?

#7

gradlew assembleDebug --stacktrace

↑This way, is it wrong?

I output the log in text, but I copied only the last one and pasted it because it is long.

I am sorry that I am unfamiliar with English.
Thank you.

#8

You can add --debug as well. If output log is too long you should post it on pastebin for example.

#9

It works!!! It helps me a lot!! I can debug now. Thanks a lot!

It don’t work. How do I set? thanks!

#11

I think this is issue, you probably using older cocos2d-x version where compiled lib was called “cocos2dcpp” not “MyGame”

Upgrade your cocos;) to 3.13.1+ or change in gradle that line

targets 'MyGame'
to

targets 'cocos2dcpp'

Target name should match with in Android.mk defined (without _shared)

LOCAL_MODULE := cocos2dcpp_shared

@energyy, appreciate your work. Using these instructions I have a project compiling and debugging from Android Studio.

What I cannot see is the C++ files in my cocos2d-x project. Can you advise me please?

Thanks again!

I have it all compiling, running. Have set the debug type to “Native” and set the symbols directory and yet when I press “debug” it does not hit any breakpoints at all…

Is really frustrating please help … here is my setup:

So I have done: edit configurations -> select app “HelloCpp” – Debug tab - > Native -> symbols directory:

  "C:\dev\firebase\cocos2dx-cpp-sample\sample_project\proj.android-studio\app\.externalNativeBuild\ndkBuild\debug\armeabi-v7a"

In build.gradle for the app I have:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'

defaultConfig {
    applicationId "org.cocos2dx.hellocpp"
    minSdkVersion 21
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"

    externalNativeBuild {
        ndkBuild {
            arguments '-j' + Runtime.runtime.availableProcessors()
        }
    }

    ndk {
        abiFilters 'x86','armeabi-v7a'
    }
}

externalNativeBuild {
    ndkBuild {
        path 'jni/Android.mk'
    }
}

sourceSets.main {
    java.srcDir "src"
    res.srcDir "res"
    jniLibs.srcDir "libs"
    manifest.srcFile "AndroidManifest.xml"
    assets.srcDir "assets"
}

signingConfigs {

   release {
        if (project.hasProperty("RELEASE_STORE_FILE")) {
            storeFile file(RELEASE_STORE_FILE)
            storePassword RELEASE_STORE_PASSWORD
            keyAlias RELEASE_KEY_ALIAS
            keyPassword RELEASE_KEY_PASSWORD
        }
    }
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        if (project.hasProperty("RELEASE_STORE_FILE")) {
            signingConfig signingConfigs.release
        }
    }
}
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile project(':libcocos2dx')
    compile 'com.google.firebase:firebase-auth:10.2.0'
    compile 'com.google.android.gms:play-services-base:10.2.0'
}

apply plugin: 'com.google.gms.google-services'

task cleanAssets(type: Delete) {
    delete 'assets'
}
task copyAssets(type: Copy) {
    from '../../Resources'
    into 'assets'
}

I solved this by upgrading to 3.15 and downgrading the NDK to 13.b. Only took most of the day to figure it out… the joys of open source. :thumbsdown:

#16

Break points are not caught. No compilation error, successful, working apk is generated. Any ideas?

#17

have u used 3.15 version?
now it should work more stable.

For those who are still having trouble with debugging, setting Run->Edit configuration - select your project -> go to tab debugger -> set debuger type to native works for me.

Why I get these errors in Android Studio?
#21

Not working for me. Here are the values:
targets 'MyGame'
From my Android.mk
LOCAL_MODULE := MyGame_shared
LOCAL_MODULE_FILENAME := libMyGame

But I still get the following error:

Error:Execution failed for task ‘:WordBounce:externalNativeBuildDebug’.

Unexpected native build target MyGame. Valid values are:

Funnily enough, the list of valid values is also empty. And… I am able to build successfully from the command line using the following command, it only fails when I try to compile from Android-Studio, Weird!!:
cocos compile -p android --android-studio --stacktrace

Can someone please help?

Thanks,

Worked on mobile, was not working on Emulator!!! Please ignore.

Best,

#23

It’s completely logical, because the default configuration for cocos2d-x is arm-based and the emulator is x86. You need to add x86 to the ABI, to use it within the emulator.
