Use ndk-build with Android Studio. #15676

chaoren · 2016-05-18T19:35:11Z

This feature depends on the latest canary preview of Android Studio. You might want to hold off on this pull request until the feature stabilizes.

minggo · 2016-05-19T03:44:13Z

Thanks @chaoren . Can i debug C++ codes after apply this patch?
And do you know when will the stable version been released?

chaoren · 2016-05-19T03:53:27Z

Can i debug C++ codes after apply this patch?

Yes. Please try it out and file bugs if you run into any.

And do you know when will the stable version been released?

I can't give you any specific dates here, but stable is usually about a month or so behind canary.

minggo · 2016-05-19T03:58:52Z

Thanks, i will have a try.

zilongshanren · 2016-05-19T05:59:37Z

[ci rebuild]

minggo · 2016-05-20T10:16:29Z

@chaoren How to test it? I just downloaded Android Studio 2.2, and click run menu, it doesn't build native codes, just build java codes and generate the app. And the CPP files are not displayed in Android Studio, then how can i set a breakpoint if we fix compiling issue?

minggo · 2016-05-20T10:18:59Z

Oh, i tested cpp-empty-test, and i found you didn't modify it. I will try by creating a new project.

minggo · 2016-05-20T10:36:31Z

It seems i blocked on importing new generated project

TheCodez · 2016-05-20T15:11:19Z

@chaoren I'm getting the following error on windows:
Error:Process 'command 'C:\NVPACK\android-sdk-windows\cmake\bin\cmake.exe'' finished with non-zero exit value 1

Any ideas?

chaoren · 2016-05-20T15:34:00Z

@minggo Ah, my apologies, I'll change the tests as well.

@TheCodez currently, you'll need to install this for it to work on Windows: https://www.microsoft.com/en-us/download/details.aspx?id=48145
We're aware of this limitation, and there has been a change that removes this requirement, however, that'll probably not be available until next week or so.

TheCodez · 2016-05-20T18:05:47Z

@chaoren Thanks, but that didn't fix the problem.

[EDIT] I created a new project and now I'm getting a different error:

Error:Execution failed for task ':HelloCpp:externalNativeBuildDebug'.

chaoren · 2016-05-20T20:16:49Z

@TheCodez are you opening the test projects or creating a new project from template and opening that?

Please provide the steps you performed before reaching that error.

TheCodez · 2016-05-20T21:14:55Z

@chaoren I just created a new project using cocos console, and opened the proj.android-studio folder in Android Studio. While doing gradle sync it's encountering the cmake error.

I've attached my log, hope it's somehow useful.
idea.txt

[EDIT] When doing Build/Clean Project I get the following output:

minggo · 2016-05-23T02:52:55Z

I met the error when importing a new project:

Gradle 'proj.android-studio' project refresh failed
  Error:A problem occurred configuring project ':MyCppGame'.

Steps to reproduce:

use cocos new -l cpp to create a new project
use Android Studio 2.2 preview 1 to import the new project
then the error happened

I uses latests cocos2d-x codes and apply this PR. And my OS is Mac OS X 10.11.4. The full log file is

idea.log.zip

Edit: i installed Android Studio 2.2 preview 1 and Android Studio 2.0.

chaoren · 2016-05-23T03:00:50Z

Could you please make sure that these SDK components are installed and up to date?

SDK Platforms -> Android 5.1 (Lollipop) 22
SDK Tools -> CMake
SDK Tools -> LLDB 2.2
SDK Tools -> NDK

We'll need to change that message to something more useful.

minggo · 2016-05-23T03:09:10Z

It seems LLDB 2.2 is missing. I will try to install it.

minggo · 2016-05-23T03:13:26Z

@chaoren My computer has Cmake, but Android Studio can not find it and ask me to install it. And i can not find a way to set Cmake path.

chaoren · 2016-05-23T03:19:06Z

The CMake integration requires the custom CMake from the SDK, so the CMake on your computer would not work. When this feature stabilizes, we'll hopefully upstream our changes to CMake, but whether the ~20MB of space is worth the additional complexity is debatable.

chaoren · 2016-05-23T03:22:50Z

@TheCodez could you please make sure that you're using the latest NDK?

minggo · 2016-05-23T03:29:56Z

@chaoren Ok, i downloaded the cmake and needed components. And it can compile the codes. But i can not see the log, for example, which cpp file is compiled, and what's the compiling flags and so on as i can before using cocos command.

chaoren · 2016-05-23T03:39:28Z

But i can not see the log, for example, which cpp file is compiled, and what's the compiling flags and so on as i can before using cocos command.

Yes, that is the expected behavior right now. We could change the compiling to be more verbose, but we'll have to look at whether the extra output would significantly slow down compilation.

minggo · 2016-05-23T06:49:43Z

@chaoren The app crashed when i clicked Debug MyCppGame-native. But it can run of i use cocos run -p android, which means the project itself is not problem.

chaoren · 2016-05-23T06:54:47Z

@minggo does clicking just run (without debug) work? Are you running against a physical device or an emulator?

minggo · 2016-05-23T06:59:33Z

No. It can not run no matter debug or not, and no matter select MyCppGame or MyCppGame-native. I tested on Android device(Sangsung S4 Zoom, Android 4.2.2).

minggo · 2016-05-23T07:02:24Z

And i found there is a strange log
Connected to the target VM, address: 'localhost:8605', transport: 'socket'

chaoren · 2016-05-23T07:06:03Z

That's a normal message when attaching the debugger.

When you say "crashed", does it just look like it's hanging, or is it opening the app then immediately closing? Could you please provide the logcat as it crashes?

minggo · 2016-05-23T07:22:15Z

It closed immediately, the logcat is

logcat.txt.zip

And i found the output MyCppGame/proj.android-studio/app/build/intermediates/cmake/debug/lib/armeabi/libMyGame.so is 42.9M, while MyCppGame/proj.android/libs/armeabi/libMyGame.so is only 10.5M. I think it is because cmake full link all modules. Instead we use LOCAL_STATIC_LIBRARIES instead of LOCAL_WHOLE_STATIC_LIBRARIES for most modules in Android.mk.

cezheng · 2016-05-23T12:08:59Z

I installed Android Studio 2.2 Preview 1 on OSX 10.11.4, checked out your branch, then created a new project. But I couldn't sync the gradle file with the project. The IDE simply got an exception.

Here's the Error Logs

chaoren · 2016-05-23T14:55:35Z

@cezheng you get that error when the NDK isn't present, please make sure SDK Tools -> NDK is installed and up to date.

piotrros · 2017-02-16T07:43:57Z

I'm using AS 2.2.3 and can see all .cpp files. Problem is with extra .h files. I have a file named "Definitions.h", it is in android.mk file, but studio isn't showing it.
As for apk size I think stripping is fine.
As for clean second attempt always works.

I had no other issues and moved all my cocos2d-x projects to android studio.
One thing, which can be annoying is when have something missing in android.mk file. Error is sooo long that it's very hard to find out what is missing. But it's just android studio :)

Also: some people report having this error: "Error: Configuration with name 'default' not found.". I don't know what causes this, because it's not happening on my device.

minggo · 2017-02-16T07:48:42Z

@piotrros you can see cocos2d-x .cpp files?

piotrros · 2017-02-16T07:52:51Z

@minggo it depends on build.gradle. When I was using cocos2d-x bundled in project I could see all cocos2d-x files. Now I use precompiled library so I naturally don't see them.

minggo · 2017-02-16T07:57:48Z

I mean with this PR, i can not see cocos2d-x files. Does it mean this PR has some problem in build.gradle?

piotrros · 2017-02-16T08:11:08Z

It should be fine. I've modified build.gradle to my own needs. Using precompiled libraries makes app compile in seconds.. By the way it's not fine to use all abiFilters (abiFilters 'x86', 'armeabi', 'armeabi-v7a', 'arm64-v8a'), apk will be huge. I'm personally using armeabi-v7a and can debug c++ code on all my devices.

minggo · 2017-02-16T08:17:18Z

@piotrros yep, we should only build one target. I will merge this PR in 3.15 if possible because we have to modify cocos command to adapt it too. And i am not familiar with build.gradle grammar. I have to learn more about it.

I have to do like this to delete unneeded folders, but is there any other way to exclude them?

android.applicationVariants.all { variant ->

        delete "${buildDir}/intermediates/assets/${variant.dirName}/project"
        delete "${buildDir}/intermediates/assets/${variant.dirName}/simulator"
    }
    variant.mergeAssets.finalizedBy rmassets

I don't directly know how to solve that problem but Gradle's FileCollection is typically how you build sets of files with exclusions.

@jomof Did the issue with the path lengths on Windows get resolved? The latest version of AS works perfectly on macOS but when trying to compile on Windows I get path length errors. When setting APP_SHORT_COMMANDS and LOCAL_SHORT_COMMANDS to true in my build.gradle if I run gradle in debug it shows that after I assign them to true they get assigned back to false.

jomof · 2017-03-23T15:43:14Z

Hi David, At this point I think all the known Windows path length issues are resolved so, depending on your environment, your issue may be something I haven't seen before. Could you open a bug at b.android.com? Regarding APP_SHORT_COMMANDS and LOCAL_SHORT_COMMANDS. We call ndk-build twice: (1) The first time is with -nB to create a build script that we analyze for metadata about the build to give to Android Studio. This is the where you see us setting these flags to false. Gnu make should not be accessing the filesystem during this phase so it should be safe with respect to path lengths. You can see the exact command we use for this by opening ndk_build_command.txt. The metadata we produce is next to this file in android_gradle_build.json. (2) Later, during the build phase, we call ndk-build again without resetting those flags. You can see the exact build command we will use by opening android_gradle_build.json in an editor and looking at libraries.{target}.buildCommand in the JSON. You should see only your use of xxx_SHORT_COMMANDS there. I'm sorry you still have path issues on Windows. I'll fix it if it is possible to do so. Please provide as much information as you can in the bug and CC my email (jomof@google.com). Thanks! Jomo
