스크린샷과 같은 그림 등이 들어가면 좋겠죠??

지금 버전인 0.7.1.6은 사실 라이브러리 빌드만 봤을때 엄청 간단하기 하지만
android-studio를 이용하지 않은 gradlew를 통한 빌드나 unit-test guide로의 확장이 가능할 것 같아요.

Title

PREREQUISITE

Does the document's page already exist?

https://github.com/euphony-io/euphony/blob/master/PREREQUISITE.md

What is the issue of docs?

Euphony v0.8.0.1 has been released, so below things also should be updated.

Suggest a potential alternative/fix

• Add euphony to your project
  • Using Maven repository (build.gradle should be updated)
  • Import the aar/jar file directly (MavenCentral euphony artifact link should be updated)
  • Request permissions to users (MainActivity sample code should be updated; As android updated, requestPermissions function was deprecated)

Anything else?

Is there an existing issue for this?

• I have searched the existing issues.

Would you like to work on the issue?

• Assign this issue to me.

Describe the bug

When I tried to build the project with API version 28 or 30, I ran into some errors.

I failed to build and faced message ninja: build stopped: subcommand failed. even though test cases were all passed.

What I've tried as far is as follows, but they didn't work.

1. Change API version 30 to 28.
2. Reduce test cases.
3. Delete /.cxx directory and rebuild.
4. Delete euphony repository in my local storage and clone again

Expected Behavior

This is what I expected to happen.

Environment

- OS: Windows 10
- API level: 28, 30

Steps to reproduce

1. Run Android Studio.
2. Create device using API version 28 or 30.
3. Run 'java-sample'.
4. See all test cases are passed.
5. See build errors.

Anything else?

I refered to these issues and discussions.

• #116 (comment)
• #63
• #45

When I used Pixel XL API 32, the project completely succeed to build.

Proposal

I think it is good to notice users who try to build with API version 28 or 30 that the API versions can make build errors. And also, how about do not run gtest with the API versions?

AS-IS

While I apply Euphony library for sample app project, I find using one more object can cause malfunciton. I think applying singleton pattern to EuRxManager can prevent potential issue.

TO-DO

Now, EuRxManager have 3 constructor.

public EuRxManager() {
		mOption = EuOption.builder()
				.modeWith(EuOption.ModeType.DEFAULT)
				.encodingWith(EuOption.CodingType.BASE16)
				.modulationWith(EuOption.ModulationType.FSK)
				.build();
	}

	public EuRxManager(RxEngineType engineType) {
		rxEngineType = engineType;
		if(rxEngineType == RxEngineType.EUPHONY_NATIVE_ENGINE)
			nativeCore = EuNativeConnector.getInstance();
		else
			nativeCore = null;
	}

	public EuRxManager(EuOption.ModeType mode) {
		mOption = EuOption.builder()
				.modeWith(mode)
				.build();
	}

I think public EuRxManager(),public EuRxManager(EuOption.ModeType mode) can be combined. And initializing nativeCore can be solved seperately by add new method.

AS-IS

EuTxManager가 사용될때 여러 인스턴스가 생성되어 사용될 경우, 오동작을 일으킬 수 있음.

• 예를 들어 EuPI를 여러개 추가할때 EuTxManager가 여러개가 되는 경우, EuPI가 제대로 관리가 안될 수 있음.

TO-DO

Singleton 적용을 통해 잠재 이슈를 사전에 방지한다.

현재 Action CI 에서는 아래와 같은 업데이트 필요

• 안드로이드16 버전 (OpenSLES 지원), 21 (aaudio) 만 테스트하면 됨
• 현재 gtest로 돌아가는 Unit-test는 Android Studio에서만 테스트되었으며, Action CI에 맞게 재수정 필요

jcenter artifactory is shutting down.

https://central.sonatype.org/publish/publish-guide/#deployment

Environment

Device : Pixel 3a (Android Emulator)
OS : Android 10
Android Studio : Arctic Fox | 2020.3.1

Describe the bug
When inserting EuRxManager object into the code, there's a problem that the app is terminated with fatal exception.
Initializing this object causes NoClassDefFoundError.

The imported Euphony is 0.7.1.6 version on the centralMaven artifact repository

implementation 'co.jbear.lib:euphony:0.7.1.6'

While looking for a way to resolve this issue, I found out that this issue may have been caused by setting 'testCoverageEnabled true' in library module.
(ref. Setting 'testCoverageEnabled true' in library module crashes app on start-up)

Fortunately, it was reflected in a084f06 recently as I looked at commit history and from the next version, it seems that this issue will not be there.
But for the unlucky person who import co.jbear.lib:euphony:0.7.1.6 like me, I thought I should report the solution to this issue.
I hope this report helps someone suffering🤣

And also, thanks to @designe comment, I got to know version prior to 0.8 is working well on jcenter.

I have no idea what's different

implementation 'euphony.lib:euphony:0.7.1.6'

and

implementation 'co.jbear.lib:euphony:0.7.1.6'

Should we add the

implementation 'co.jbear.lib:euphony:0.7.1.6'
??

library content is not different.
but,
euphony.lib:euphony:0.7.1.6 is on the jcenter
and co.jbear.lib:euphony:0.7.1.6 is on the centralMaven

We're going to use centralMaven after 0.8 version, because jcenter artifact repository was sunset last year :(
Previous uploaded version is working well on jcenter.
So, don't care about centralMaven version in v0.7.1.6

So the simplest solution is to use euphony.lib:euphony:0.7.1.6!

implementation 'euphony.lib:euphony:0.7.1.6'

Thanks to @kuro11pow2 , I find an bug during Base32 gtest!

TestParamType(std::vector<u_int8_t>{ 0x10, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0 }, "100000000")

It is a special case because it goes 1 00000000000000000000 00000000000000000000. And when 00000000000000000000 enters the bitsToBase32 function, nothing happens because of the condition of while loop while(value != 0).

The best way I think is to add exception code to catch 00000000000000000000input case.

if(!value)result = "0000";

Because it is an unusual case.

I'm really appreciate to 'kuro11pow2' for making a sharp test case.
Please give me some solution or I'll make PR with my solution.

Environment

• Windows 10
• Android Studio 4.2.2
• git pull euphony master code

How to reproduce

• git pull euphony master
• build euphony with no devices connected (build successful)
• modify test code
  • test code: euphony/src/main/cpp/tests/base16Test.cpp
  • change line 32 like below:

    TestParamType(std::vector<u_int8_t>{ 0x61 }, "621"),

• connect android device (Galaxy S20 FE)
• build euphony with device connected
  
• build is successful (It should be failed!!)

Question

Why build success, even if test code has problem?
How can I resolve this?

Discussed in https://github.com/orgs/euphony-io/discussions/259

Issue 원인

• EuOption 클래스는 모두 동일하게 쓰여진다. 만들어진 EuOption은 동일하게 사용되기 때문에 Singleton으로 한번만 생성된 후 이를 공유하는 것이 효율성 측면에서 적합하다고 판단된다.
• 또한 사용성 측면에서 어려움이 있을 수 있으므로 Builder 패턴으로 사용자 입장에서 정리되면 좋을 것 같다.

해결책

EuOption의 Singleton 패턴 적용

This project does not specify a minimum version of Android.
Is the library also available in Android 7.0 (API level 24)? Please specify the minimum version in README.

이 프로젝트에는 안드로이드 최소 버전이 명시되어 있지 않습니다.
안드로이드 API 24 버전에서도 라이브러리 사용이 가능합니까? README에 최소 버전을 명시해주었으면 좋겠습니다.

AS-IS

• Artifacts published in maven central are easy to use.
• There is the inconvenience of porting aar library extracted by building euphony library
• Currently, after creating a new project, it is necessary to link the app and the euphony library.

Idea

• Suggested Idea : https://github.com/orgs/euphony-io/discussions/186
