Generating APK build error android studio

rahul_d_v · September 3, 2020, 7:39pm

Hey all,

I have a ready application. I can use it by running from android studio but while generating apk for it, I got a build error

Build command failed.
Error while executing process C:\Users\itsme\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\ninja.exe with arguments {-C C:\Development\android cocos games\Jump\cocos2d\cocos\platform\android\libcocos2dx\.cxx\cmake\debug\x86_64 MyGame}

Box2d is missing?

rahul_d_v · September 3, 2020, 8:16pm

I have Box2d. But inside Box2d/prebuilt/android/ folder, there are only these three folders:
arm64-v8a, armeabi-v7a, x86
and error is something related to x86_64 which is not there Screenshot (155)

slackmoehrle · September 3, 2020, 8:17pm

I’m not exactly sure, but does it have something to do with this line?

rahul_d_v · September 3, 2020, 8:31pm

Actually in the fresh project there were these lines
ndk {
abiFilters = []
abiFilters.addAll(PROP_APP_ABI.split(’:’).collect{it as String})
}
instead of this

but I was getting some syncing error. So I changed it according to studio refence https://developer.android.com/studio/projects/gradle-external-native-builds

If you’re going to build for x86 and x86_64, then you’ll have to build your own version of the x86_64 Box2D library.

The alternative is to not use the prebuilt version that comes with Cocos2d-x, and just build it from source.

For example, download the Box2d source code from here, put it in your [gameproject]/external/Box2D folder, and then modify your game project root CMakeLists.txt to build and link the library:

#disable the built-in Box2D first
set(BUILD_EXT_BOX2D OFF CACHE BOOL "Build with internal Box2D support" FORCE)

# build and link the Box2D source
add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/external/Box2D ${PROJECT_BINARY_DIR}/Box2D)
get_target_property(box2d_INCLUDE_DIRS Box2D INTERFACE_INCLUDE_DIRECTORIES)
target_include_directories(cocos2d PRIVATE ${box2d_INCLUDE_DIRS}) #cocos2d lib needs the path too
target_link_libraries(${APP_NAME} PRIVATE Box2D)
target_include_directories(${APP_NAME}
	PRIVATE ${box2d_INCLUDE_DIRS}
)

Here’s an example Box2D CMakeLists.txt, and from it you can figure out how to organise the source code for Box2D:

cmake_minimum_required(VERSION 3.6)

project(Box2D)

if(UNIX)
	set(BOX2D_INSTALL_BY_DEFAULT ON)
else(UNIX)

Ohh Okay. Thanks for your help. I will apply those changes and then tell if it works for me.

R101 · September 4, 2020, 6:08pm

Everything posted above is from one of my projects, so there is no reason it shouldn’t work for you.

rahul_d_v · September 4, 2020, 6:10pm

Okay. I will apply those changes.

R101 · September 4, 2020, 6:33pm

Is there any good reason to support x86/x86_64 for Android? x86 devices have a tiny segment of the market. You can save yourself a lot of time by avoiding x86/x86_64, assuming you don’t have a specific reason to support them.

rahul_d_v · September 4, 2020, 6:44pm

No, actually I add them because of this.

can you please tell me how to avoid them because, I reverted those abiFilters lines as default but it was showing same error even after that

R101 · September 5, 2020, 2:14am

You should be setting them in gradle.properties:

# List of CPU Archtexture to build that application with
# Available architextures (armeabi-v7a | arm64-v8a | x86)
# To build for multiple architexture, use the `:` between them
# Example - PROP_APP_ABI=armeabi-v7a:arm64-v8a:x86
PROP_APP_ABI=armeabi-v7a:arm64-v8a

The gradle.properties would have been generated with your new project. A text search for PROP_APP_ABI across your project files would have shown you that in the results.

rahul_d_v · September 5, 2020, 10:45am

Hey @R101 Thank you for your help. Both methods work for me.

I applied it on another project and it works
