## Feature in detail
|
|
|
|
### Full Android Studio supports
|
|
|
|
Since v3.15, can use Android Studio 2.3+ to edit, compile and debug c++ codes. What you need to do is just use Android Studio to open `proj.android-studio`(such as `tests/cpp-empty-test/proj.android-studio`), then click run menu button to run on Android devices or simulators.
|
|
|
|
Please refer to [this doc](https://github.com/chukong/cocos-docs/blob/v3-unified-documentation/installation/Android-Studio.md) for detail usage.

|
### Audio engine improved on Android
|
|
|
|
Before v3.15, new Audio engine uses OpenSL ES to decode and play audio files. But many Android device manufacturers modify OpenSL ES decoding codes which cause issues. [This thread](http://discuss.cocos2d-x.org/t/android-audio-decoding-issues-discussion/34610) lists many issues caused by it.
|
|
|
|
In order to fix these issues, we decide to use 3rd party audio decoding libraries [tremolo](http://wss.co.uk/pinknoise/tremolo/) and __MP3 Decoder Library__, which are used by Android have good performance and stability. What's exciting is what, after using `tremolo`, the audio engine's performance is highly improved too.

|
### Remove support for Windows 8.1 store and phone
|
|
|
|
MS guys maintain Windows 8.1. They think there is not need to support it, so they remove the support.
|
|
|
|
### Remove linux 32-bit support
|
|
|
|
Most PC are 64-bit, so we decide to remove linux 32-bit support. By remove 32-bit linux support, cocos2d-x zip file is more less, and we can have more resource on more important things.
|
|
|
|
If you need linux 32-bit support, you can build the 3rd party libraries through [cocos2d-x-3rd-party-libs-src repo](https://github.com/cocos2d/cocos2d-x-3rd-party-libs-src) by yourself.

|
## misc
|
|
|
|
[Android SDK Tools 25.3.0+](http://tools.android.com/recent/androidsdktoolsrevision2530feb2017) removes __ant script__ and __android tool__, which leads to that cocos command can not generate apk files with Eclipse projects(proj.android). Currently, cocos command will do nothing if using SDK Tools 25.3.0+, you can use these two methods to fix it:
|
|
|
|
* copy `tools` folder from old Android SDK version
|
|
* use Android Studio to build the app
|
|
|
|
It seems google doesn't want developers continue to use Eclipse to develope Android applications, so i suggest to switch to use Android Studio.
