PLEASE DONT MERGE BEFORE DEVELOPERS TEST IT. AND MORE COMMENTS NEED TO BE ADDED.

This Pull Request has done the following things:

• Supports to preload small audio files and cache them with PCM data buffer
• MP3/Ogg/... files are decoded to PCM data by OpenSLES API
• Decoded PCM buffer data matches the best sample rate & buffer size in frames of device by using resampling source code in Android Source (Android 6.0, platform/frameworks/av)
• Big refactoring for the implementation of AudioEngineImpl for Android, better class responsibility
• Mixing audio clips by ourself, in this way, we only need a single OpenSLES AudioPlayer for playing many clips and this will fix latency of making a AudioPlayer active and play a track. For now, we only support 32 audio clips being played simultaneously. But AudioEngine module has limited it to 24 clips by default.
• Adds audio performance test case
• Supports to preload audio files asynchronously.

Please help to test it on the Android devices which have low performance. Thanks :)

Some developers report there is performance issue on Android, specially on Android 6.0 + QHD devices. There are also many tickets in forum reporting about it: http://discuss.cocos2d-x.org/t/cocos2d-x-and-poor-updates/29296.

Steps to Reproduce: input Chinese in TextField just recieve one charactor in setMarketedText , input number or English both ok.

Description

From time to time, if I exit my game on Android while text is being displayed with CCLabelTTF, then when I re-enter the game, the text is replaced with black boxes. I’m guessing the texture is getting lost. All other textures are fine though.

Another way to reproduce the issue:

start game

launch some activity (such as an interstitial ad)

close that activity and return to game

at this point, have CCLabelTTF display some text ==> here the text is just black boxes

Also, here’s a related forum post in which more than one developer have experienced this issue: http://cocos2d-x.org/forums/6/topics/42500

Comments

• Sheado added comment: Ok,

After tinkering I found the cause of the problem. I was preparing my CCLabelTTF in applicationWillEnterForeground(). Simply moving the code to a runAction(…callfunc…) fixes the problem.

I don’t know if this is a bug or if the documentation just needs to be updated to warn people that they should schedule the work to be done on resuming the application.

• wollf added comment: Problem exists with new Label::createFromTTF. If i create a label label like so: Label::createWithTTF(fontBig,"Example ttf text",TextHAlignment::RIGHT); I hide app to background (pressing HOME button) and when i re-enter it i get "white boxes". normal label: after re-entering:

I think this is caused by not reloading ttfConfig created resources in reloadAllTextures. This is bad and must be fixed, though i can't deal with this myself :( Tested Device: Google Nexus 7(2013)

• yaxinhoo added comment: @Sheado i got the same , does it fixed?
• WenHai added comment: Hi guys,which version of Cocos2d-x are you using?

After around 10 min of playing on my game the AudioPlayer stopped playing the audio and start giving me this message on play2d .

cocos2d::experimental::AudioPlayer::play2d(cocos2d::experimental::AudioCache *):alGenBuffers error code:a003 I tried to clear the cash and re cash on replacing the scenes and it did't fix it . i tried to

experimental::AudioEngine::end(); But the game crash .

This should fix 3 issue with my previous path for cmake build system.

• Compile errors in MacOS X 10.8 (yes too old, but forum post show that exists people that use it)
• Link with static libraries determined with pkg-config --static --libs not works on almost any Linux distros. So do not try to do it ever. (Someone who needs fully static build on linux, can improve prebuilt libs in external).
• FindFontconfig.cmake failed to find library on centos, because check FONTCONFIG_INCLUDE_DIRS, but on centos pkg-config returns empty include dirs, because package in standard search location for compiler.

All this fixed now. And tested, but not against current state. Because after commit: Merge pull request #9193 from pipu/v3_flatbuffers build fully broken as folder external not contains source code for flatbuffers (

Using iPhone 6 and 6 Plus, we do not return the proper resolution for those devices.

The proper resolutions are here: http://www.iosres.com

Justin thinks that the UIView is returning a scale factor of 2 instead of 3, but I haven't been able to test this quite yet.

Also, even doing something like:

glGetIntegerv(GL_VIEWPORT,m_viewport);

returns the wrong values.

1. Fix the bug if a node has a parent, it's physics body position is incorrect.
2. Set anchor point to middle when invoke Node::setPhysicsBody
3. Add PhysicsBody set/getPosition/RotationOffset method.
4. Add PhysicsPositionRotationTest.

This is the process to see this bug:

1. cocos new test_project -p com.test.test -l cpp
2. cd test_project
3. python /Users/jun/Code/cocos2d-x-3.12/tools/cocos2d-console/bin/cocos.py  compile -p android --android-studio --ap android-15 --ndk-mode release --mode release  --output-dir .
4. adb install test_project-release-signed.apk

When run this test app in android 5.0.2 device (Nexus 7) , it will crash! but in android 4.4 and android 6.0, it was no problem.

The ndk version is r11c

Hello,

I'm looking for a RadialGradientLayer for cocos2d-x. Discussion started here http://discuss.cocos2d-x.org/t/radial-gradient/26602/6

I don't know OpenGL and shaders, so I can't implement it in any way. Really looking for solution from cocos2d-x developers.

Some helpful links from thread: https://github.com/saeedafshari/ShaderLayer https://github.com/SFML/SFML/wiki/Source:-Radial-Gradient-Shader

Can this feature be added to cocos2d-x? I believe this should be easy to implement for cocos2d-x developers..

Just updated Android SDK tools to the latest version 25.3.1 and now tools/android.bat no longer works, it reports:

The "android" command is no longer available.
For manual SDK and AVD management, please use Android Studio.
For command-line tools, use
tools\bin\sdkmanager.bat and tools\bin\avdmanager.bat
Error running command, return code: 1.

• 可能存在问题：如果一个定时器，处理的事情的函数，占用时间超过定时器时间间隔，会导致这个定时器一直处在循环处理事件中，其它定时器没有机会处理事件。 一般来说，客户端的定时器，我们不会太依赖它的时间精度，所以，建议把Timer::update里的while循环去掉！

It would seem that as it is, this engine can no longer be used to build games which can be published on the Google Play Store.

As of November 2022 Google Play Store uploads require Android 12 ( API level 31 ) as a minimum target API level.

Android 12's minimum required NDK version is now NDK r23 (NDK 23.0.7599858)

Steps I took to fix:

1. Download a compatible NDK ( I used NDK 23.0.7599858 )
2. Remove ndk.dir= from local.properties file
3. Add ndkVersion = "23.2.8568313" to project level build.gradle file
4. Add implementation 'androidx.work:work-runtime-ktx:2.7.0' to project level build.gradle dependencies
