如何将一个JavaEE的SDK依赖到Android中

1. 前言

最近有个需求，需要集成阿里的一个SDK : 通义听悟，但是这个SDK是专门给Web端JavaEE使用的，所以导致接入后，运行报错，有兼容性问题，该如何解决，使其能在Android中正常运行呢 ?

2. 添加Maven依赖

首先添加Maven依赖

implementation(
    group = "com.aliyun",
    name = "aliyun-java-sdk-core",
    version = "4.6.0"
)
implementation(
    group = "com.alibaba",
    name = "fastjson",
    version = "1.2.83"
)

这个时候会提示报错，有资源冲突

Execution failed for task ':app:mergeDebugJavaResource'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.MergeJavaResWorkAction
   > 2 files found with path 'META-INF/DEPENDENCIES' from inputs:
      - C:\Users\Haokai.Zhu\.gradle\caches\modules-2\files-2.1\org.apache.httpcomponents\httpclient\4.5.13\e5f6cae5ca7ecaac1ec2827a9e2d65ae2869cada\httpclient-4.5.13.jar
      - C:\Users\Haokai.Zhu\.gradle\caches\modules-2\files-2.1\org.apache.httpcomponents\httpcore\4.4.15\7f2e0c573eaa7a74bac2e89b359e1f73d92a0a1d\httpcore-4.4.15.jar
     Adding a packaging block may help, please refer to
     https://developer.android.com/reference/tools/gradle-api/8.3/com/android/build/api/dsl/Packaging
     for more information

接着我们解决这个冲突，在build.gradle的android闭包下，添加如下配置

packaging {
    resources {
        excludes += "/META-INF/{AL2.0,LGPL2.1}"
        excludes += "META-INF/DEPENDENCIES"
        excludes += "META-INF/LICENSE.md"
        excludes += "META-INF/NOTICE.md"
        excludes += "META-INF/INDEX.LIST"
        excludes += "META-INF/io.netty.versions.properties"
    }
}

这个时候再重新编译运行，可以发现，可以正常运行到手机上了。

3. 音视频文件离线转写

接着，我们借助阿里听悟SDK的能力，将完整的音频文件转写记录为文本。
具体代码如下

public class TranscriptionTest {

    public void testFiletrans() throws ClientException {
        CommonRequest request = createCommonRequest("tingwu.cn-beijing.aliyuncs.com", "2023-09-30", ProtocolType.HTTPS, MethodType.PUT, "/openapi/tingwu/v2/tasks");
        request.putQueryParameter("type", "offline");

        JSONObject root = new JSONObject();
        root.put("AppKey", Constants.AppKey);

        JSONObject input = new JSONObject();
        //input.fluentPut("FileUrl", "输入待测试的音频url链接")
        input.fluentPut("FileUrl", "https://www.cambridgeenglish.org/images/153149-movers-sample-listening-test-vol2.mp3")
                .fluentPut("SourceLanguage", "en")
                .fluentPut("TaskKey", "task" + System.currentTimeMillis());
        root.put("Input", input);

        JSONObject parameters = new JSONObject();
        JSONObject transcription = new JSONObject();
        transcription.put("DiarizationEnabled", true);
        JSONObject speakerCount = new JSONObject();
        speakerCount.put("SpeakerCount", 2);
        transcription.put("Diarization", speakerCount);
        parameters.put("Transcription", transcription);
        root.put("Parameters", parameters);
        System.out.println(root.toJSONString());
        request.setHttpContent(root.toJSONString().getBytes(), "utf-8", FormatType.JSON);

        DefaultProfile profile = DefaultProfile.getProfile("cn-beijing", Constants.AccessKeyId, Constants.AccessKeyPassword);
        IAcsClient client = new DefaultAcsClient(profile);
        CommonResponse response = client.getCommonResponse(request);
        System.out.println(response.getData());
    }
    public static CommonRequest createCommonRequest(String domain, String version, ProtocolType protocolType, MethodType method, String uri) {
        // 创建API请求并设置参数
        CommonRequest request = new CommonRequest();
        request.setSysDomain(domain);
        request.setSysVersion(version);
        request.setSysProtocol(protocolType);
        request.setSysMethod(method);
        request.setSysUriPattern(uri);
        request.setHttpContentType(FormatType.JSON);
        return request;
    }
}

然后再Activity里调用

binding.btnTest1.setOnClickListener {
    TranscriptionTest().testFiletrans()
}

运行程序，发现报错 : java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier

Process: com.heiko.alitingwu, PID: 5944
java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; or its superclasses (declaration of 'org.apache.http.conn.ssl.AllowAllHostnameVerifier' appears in /system/framework/framework.jar!classes5.dex)

找不到org/apache/http/conn/ssl/AllowAllHostnameVerifier这个类 ?
依稀记得老版本的Android里，是将Apache的HttpClient给移除掉的，所以这里会找不到相关的类。

那要怎么办呢 ?

其实网上很多文章写的已经很明白了 : https://blog.csdn.net/divaid/article/details/121154062。
要用cz.msebera.android:httpclient:4.5.8这个库来替换Apache的HttpClient，并将相关的引用也一并做修改。
但是阿里听悟的aliyun-java-sdk-core这个SDK是已经封装好的，需要怎样才能将Apache的HttpClient修改为cz.msebera.android:httpclient呢 ?

4. 实现自己的aliyun-java-sdk-core

4.1 复制代码

好在aliyun-java-sdk-core这个库没有做混淆。我们直接将aliyun-java-sdk-core SDK里面的代码复制到我们自己的项目中

在这里插入图片描述

4.2 引用需要的maven依赖

接着我们查看pom.xml文件，将需要的maven依赖改为gradle依赖，添加到我们的Android项目中

在这里插入图片描述
这里值得注意的是，可以使用ChatGPT来帮助我们节省这个重复性工作。

在这里插入图片描述
最终需要添加的Maven依赖如下

	// Gson 依赖
    implementation("com.google.code.gson:gson:2.8.9")

    // Apache HttpClient 依赖
    implementation("org.apache.httpcomponents:httpclient:4.5.13")
    // Apache HttpCore 依赖
    implementation("org.apache.httpcomponents:httpcore:4.4.15")

    // Commons Logging 依赖
    implementation("commons-logging:commons-logging:1.2")

    // Apache Commons Lang3 依赖
    implementation("org.apache.commons:commons-lang3:3.5")

    // JAXB API 依赖
    implementation("javax.xml.bind:jaxb-api:2.3.1") //2.4.0

    // JAXB Runtime 依赖
    implementation("org.glassfish.jaxb:jaxb-runtime:3.0.2")

    // Bouncy Castle 依赖
    implementation("org.bouncycastle:bcprov-jdk15on:1.70")

    // Mockito 依赖
    //testImplementation("org.mockito:mockito-core:${mockito.version}")

    // PowerMock 依赖
    //testImplementation("org.powermock:powermock-core:${powermock.version}")
    //testImplementation("org.powermock:powermock-reflect:${powermock.version}")

    // PowerMock 依赖
    //testImplementation("org.powermock:powermock-module-junit4:${powermock.version}")
    //testImplementation("org.powermock:powermock-api-mockito2:${powermock.version}")

    // JaCoCo 依赖
    //jacocoAgent("org.jacoco:org.jacoco.agent:0.8.7:runtime")

    // Lombok 依赖
    annotationProcessor("org.projectlombok:lombok:1.18.22")
    kapt("org.projectlombok:lombok:1.18.22") // 如果你使用的是 Kotlin，则需要使用 kapt 替代 annotationProcessor
    //providedCompileOnly("org.projectlombok:lombok:1.18.22")
    compileOnly("org.projectlombok:lombok:1.18.22")

    // INI4J 依赖
    implementation("org.ini4j:ini4j:0.5.4")

    // SLF4J 依赖
    implementation("org.slf4j:slf4j-api:1.7.32")
    testImplementation("org.slf4j:slf4j-simple:1.7.32")

    // OpenTracing 依赖
    implementation("io.opentracing:opentracing-api:0.33.0")
    implementation("io.opentracing:opentracing-util:0.33.0")

删除原本的aliyun-java-sdk-core依赖

implementation(
    group = "com.aliyun",
    name = "aliyun-java-sdk-core",
    version = "4.6.0"
)

接着编译运行，可以发现依然会报NoSuchFieldError的错误，但是这时候我们就可以去修改相关代码了。

4.3 使用`cz.msebera.android:httpclient`

接着将httpClient修改为cz.msebera.android:httpclient

//implementation("org.apache.httpcomponents:httpclient-android:4.3.5")
// 如果还需要httpcore的话
//implementation("org.apache.httpcomponents:httpcore:4.4.15")
implementation("cz.msebera.android:httpclient:4.5.8")

接着Sync下项目，把包引用中的org.apache.http.client修改为cz.msebera.android.httpclient

比如

//import org.apache.http.client.CredentialsProvider;
修改为
import cz.msebera.android.httpclient.client.CredentialsProvider;

注意这里LogUnit用到了自动生成get、set的lombok框架，我们这里改用手动生成get、set

4.4 依旧报错 : 找不到ManagementFactory

接着运行，会报错java.lang.management.ManagementFactory不存在

E:\WorkSpace\Android\Ali\AliTingWu\app\src\main\java\com\aliyuncs\utils\LogUtils.java:107: 错误: 程序包java.lang.management不存在
                java.lang.management.ManagementFactory.getRuntimeMXBean().getName();
                                    ^

我们来看一下这里的代码

public static long getCurrentPID() {
    String processName =
            java.lang.management.ManagementFactory.getRuntimeMXBean().getName();
    return Long.parseLong(processName.split("@")[0]);
}

可以发现，这里是获取进程ID，这里可以改成获取Android的进程ID，或者直接图省事写死

public static long getCurrentPID() {
    String processName = "myPID";
    return Long.parseLong(processName.split("@")[0]);
}

4.5 依旧报错 : 无法访问XMLEventReader

接着运行，会发现报这个错 :

E:\WorkSpace\Android\Ali\AliTingWu\app\src\main\java\com\aliyuncs\unmarshaller\XmlUnmashaller.java:18: 错误: 无法访问XMLEventReader
            return (T) unmarshaller.unmarshal(new StringReader(content));
                                   ^
  找不到javax.xml.stream.XMLEventReader的类文件

来看下XmlUnmashaller这个类

public class XmlUnmashaller implements Unmarshaller {

    @Override
    public <T extends AcsResponse> T unmarshal(Class<T> clazz, String content) throws ClientException {
        try {
            JAXBContext jc = JAXBContext.newInstance(clazz);
            javax.xml.bind.Unmarshaller unmarshaller = jc.createUnmarshaller();
            return (T) unmarshaller.unmarshal(new StringReader(content));
        } catch (JAXBException e) {
            throw newUnmarshalException(clazz, content, e);
        }
    }

    private ClientException newUnmarshalException(Class<?> clazz, String xmlContent, Exception e) {
        return new ClientException("SDK.UnmarshalFailed",
                "unmarshal response from xml content failed, clazz = " + clazz.getSimpleName() + ", origin response = " + xmlContent, e);
    }
}

接着往上看，XmlUnmashaller是在哪里调用的 ?
可以发现UnmarshallerFactory中，会去创建XmlUnmashaller

public class UnmarshallerFactory {

    public static Unmarshaller getUnmarshaller(FormatType format) throws IllegalStateException {
        switch (format) {
            case JSON:
                return new JsonUnmashaller();
            case XML:
                return new XmlUnmashaller();
            default:
                throw new IllegalStateException("Unsupported response format: " + format);
        }
    }
}

由于我们这里明确会使用Json，所以Xml相关的代码可以注释掉

public class UnmarshallerFactory {

    public static Unmarshaller getUnmarshaller(FormatType format) throws IllegalStateException {
        switch (format) {
            case JSON:
                return new JsonUnmashaller();
            /*case XML:
                return new XmlUnmashaller();*/
            default:
                throw new IllegalStateException("Unsupported response format: " + format);
        }
    }
}

/*public class XmlUnmashaller implements Unmarshaller {

    @Override
    public <T extends AcsResponse> T unmarshal(Class<T> clazz, String content) throws ClientException {
        try {
            JAXBContext jc = JAXBContext.newInstance(clazz);
            javax.xml.bind.Unmarshaller unmarshaller = jc.createUnmarshaller();
            return (T) unmarshaller.unmarshal(new StringReader(content));
        } catch (JAXBException e) {
            throw newUnmarshalException(clazz, content, e);
        }
    }

    private ClientException newUnmarshalException(Class<?> clazz, String xmlContent, Exception e) {
        return new ClientException("SDK.UnmarshalFailed",
                "unmarshal response from xml content failed, clazz = " + clazz.getSimpleName() + ", origin response = " + xmlContent, e);
    }
}*/

4.6 依旧报错 : 未找到project.properties

接着编译运行，可以发现运行成功了。
但是在执行的时候，却又报了错 : NullPointerException: Attempt to invoke virtual method 'int java.io.Reader.read(char[])'

我们定位到UserAgentConfig的props.load(UserAgentConfig.class.getClassLoader().getResourceAsStream("project.properties"));这行代码

static {
    Properties sysProps = System.getProperties();
    String coreVersion = "";
    Properties props = new Properties();
    try {
        props.load(UserAgentConfig.class.getClassLoader().getResourceAsStream("project.properties"));
        coreVersion = props.getProperty("sdk.project.version");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    DEFAULT_MESSAGE = String.format("AlibabaCloud (%s; %s) Java/%s %s/%s", sysProps.getProperty("os.name"), sysProps
            .getProperty("os.arch"), sysProps.getProperty("java.runtime.version"), "Core", coreVersion);
}

可以看到，这里去加载了一个project.properties的配置文件。所以我们需要将aliyun-java-sdk-core SDK中的这个配置文件里的内容给拿过来。可以看到，这里只是指定了版本号。
在这里插入图片描述
所以我们直接在代码里写死即可

static {
    Properties sysProps = System.getProperties();
    String coreVersion = "4.6.0";
    /*
    Properties props = new Properties();
    try {
        props.load(UserAgentConfig.class.getClassLoader().getResourceAsStream("project.properties"));
        coreVersion = props.getProperty("sdk.project.version");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }*/
    DEFAULT_MESSAGE = String.format("AlibabaCloud (%s; %s) Java/%s %s/%s", sysProps.getProperty("os.name"), sysProps
            .getProperty("os.arch"), sysProps.getProperty("java.runtime.version"), "Core", coreVersion);
}

具体报错定位到LocalConfigRegionalEndpointResolver

protected static final String ENDPOINT_JSON = "endpoints.json";

static {
    Scanner scanner = null;
    try {
        ClassLoader classLoader = LocalConfigRegionalEndpointResolver.class.getClassLoader();
        InputStream is = classLoader.getResourceAsStream(ENDPOINT_JSON);
        scanner = new Scanner(is, "UTF-8");
        scanner.useDelimiter("\0");
        String jsonStr = scanner.hasNext() ? scanner.next() : "";
        ENDPOINTS_JSON = JsonParser.parseString(jsonStr).getAsJsonObject();
    } finally {
        if (null != scanner) {
            scanner.close();
        }
    }
}

可以看到，这里去读取了endpoints.json这个文件，同样我们去aliyun-java-sdk-core SDK里，找到endpoints.json 在这里插入图片描述
这里发现endpoints.json这个文件里数据比较多，所以我们将这个文件直接复制到Android项目的asserts文件夹下

接着在代码中去读取这个文件

static {
    Scanner scanner = null;
    try {
        //ClassLoader classLoader = LocalConfigRegionalEndpointResolver.class.getClassLoader();
        //InputStream is = classLoader.getResourceAsStream(ENDPOINT_JSON);
        InputStream is = null;
        try {
            is = MyApp.getContext().getAssets().open(ENDPOINT_JSON);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        scanner = new Scanner(is, "UTF-8");
        scanner.useDelimiter("\0");
        String jsonStr = scanner.hasNext() ? scanner.next() : "";
        ENDPOINTS_JSON = JsonParser.parseString(jsonStr).getAsJsonObject();
    } finally {
        if (null != scanner) {
            scanner.close();
        }
    }
}

4.8 依旧报错 : 未找到DatatypeFactoryImpl

接着运行，会报这个错ClassNotFoundException: Didn't find class "org.apache.xerces.jaxp.datatype.DatatypeFactoryImpl"，看字面意思，Class没找到，不得其解。

最终是定位到HmacSHA1Signer类里的这行代码DatatypeConverter.printBase64Binary(signData);

@Override
public String signString(String stringToSign, String accessKeySecret) {
    try {
        Mac mac = Mac.getInstance(ALGORITHM_NAME);
        mac.init(new SecretKeySpec(accessKeySecret.getBytes(ENCODING), ALGORITHM_NAME));
        byte[] signData = mac.doFinal(stringToSign.getBytes(ENCODING));
        return DatatypeConverter.printBase64Binary(signData);
    } catch (NoSuchAlgorithmException e) {
        throw new IllegalArgumentException(e.toString());
    } catch (UnsupportedEncodingException e) {
        throw new IllegalArgumentException(e.toString());
    } catch (InvalidKeyException e) {
        throw new IllegalArgumentException(e.toString());
    }
}

看上去解决这个ClassNotFoundException没找到的问题比较难，所以我这里想绕过这个问题。
我们进入printBase64Binary方法看下源码，可以发现最终只调用了这些代码，所以我们把这些代码复制出来

public static String _printBase64Binary(byte[] input) {
    return _printBase64Binary(input, 0, input.length);
}

public static String _printBase64Binary(byte[] input, int offset, int len) {
    char[] buf = new char[((len + 2) / 3) * 4];
    int ptr = _printBase64Binary(input, offset, len, buf, 0);
    assert ptr == buf.length;
    return new String(buf);
}

private static final char[] encodeMap = initEncodeMap();

private static char[] initEncodeMap() {
    char[] map = new char[64];
    int i;
    for (i = 0; i < 26; i++) {
        map[i] = (char) ('A' + i);
    }
    for (i = 26; i < 52; i++) {
        map[i] = (char) ('a' + (i - 26));
    }
    for (i = 52; i < 62; i++) {
        map[i] = (char) ('0' + (i - 52));
    }
    map[62] = '+';
    map[63] = '/';

    return map;
}

public static char encode(int i) {
    return encodeMap[i & 0x3F];
}

public static int _printBase64Binary(byte[] input, int offset, int len, char[] buf, int ptr) {
    // encode elements until only 1 or 2 elements are left to encode
    int remaining = len;
    int i;
    for (i = offset;remaining >= 3; remaining -= 3, i += 3) {
        buf[ptr++] = encode(input[i] >> 2);
        buf[ptr++] = encode(
                ((input[i] & 0x3) << 4)
                        | ((input[i + 1] >> 4) & 0xF));
        buf[ptr++] = encode(
                ((input[i + 1] & 0xF) << 2)
                        | ((input[i + 2] >> 6) & 0x3));
        buf[ptr++] = encode(input[i + 2] & 0x3F);
    }
    // encode when exactly 1 element (left) to encode
    if (remaining == 1) {
        buf[ptr++] = encode(input[i] >> 2);
        buf[ptr++] = encode(((input[i]) & 0x3) << 4);
        buf[ptr++] = '=';
        buf[ptr++] = '=';
    }
    // encode when exactly 2 elements (left) to encode
    if (remaining == 2) {
        buf[ptr++] = encode(input[i] >> 2);
        buf[ptr++] = encode(((input[i] & 0x3) << 4)
                | ((input[i + 1] >> 4) & 0xF));
        buf[ptr++] = encode((input[i + 1] & 0xF) << 2);
        buf[ptr++] = '=';
    }
    return ptr;
}

将DatatypeConverter.printBase64Binary(signData);的调用改为调用return _printBase64Binary(signData);

4.9 依旧报错 : 乍一看报错日志很多

接着运行，发现这个报错，乍一看报错很多

定眼一看发现有这么一句Caused by: android.os.NetworkOnMainThreadException。
哦，这个调用要在异步线程，所以我们让其跑在异步线程。

binding.btnTest1.setOnClickListener {
    Thread {
        TranscriptionTest().testFiletrans()
    }.start()
}

5. 再次运行

可以发现运行成功了，打印出了如下日志

{"Code":"0","Data":{"TaskId":"5de301246fac411b8cc2bec2b2388d6b","TaskKey":"task1712908506219","TaskStatus":"ONGOING"},"Message":"success","RequestId":"9F757993-29AD-56F4-99FA-A0A55255930F"}

到这里，阿里听悟接入Android的兼容性问题就都已经解决了。接着我们可以再来调用下阿里听悟SDK的其他方法。

5.1 获取任务状态

这个是用来查询任务的状态

public class GetTaskInfoTest {

    public void getTaskInfo(String taskId) throws ClientException {
        //String taskId = "请输入创建任务(含离线转写、实时会议)的TaskId";
        String queryUrl = String.format("/openapi/tingwu/v2/tasks" + "/%s", taskId);

        CommonRequest request = createCommonRequest("tingwu.cn-beijing.aliyuncs.com", "2023-09-30", ProtocolType.HTTPS, MethodType.GET, queryUrl);
        DefaultProfile profile = DefaultProfile.getProfile("cn-beijing", Constants.AccessKeyId,Constants.AccessKeyPassword);
        IAcsClient client = new DefaultAcsClient(profile);
        CommonResponse response = client.getCommonResponse(request);
        System.out.println(response.getData());
    }
    public static CommonRequest createCommonRequest(String domain, String version, ProtocolType protocolType, MethodType method, String uri) {
        // 创建API请求并设置参数
        CommonRequest request = new CommonRequest();
        request.setSysDomain(domain);
        request.setSysVersion(version);
        request.setSysProtocol(protocolType);
        request.setSysMethod(method);
        request.setSysUriPattern(uri);
        request.setHttpContentType(FormatType.JSON);
        return request;
    }
}

进行调用

binding.btnTest2.setOnClickListener {
    Thread {
        GetTaskInfoTest().getTaskInfo("5de301246fac411b8cc2bec2b2388d6b")
    }.start()
}

可以发现打印如下日志

{"Code":"0","Data":{"TaskId":"5de301246fac411b8cc2bec2b2388d6b","TaskKey":"task1712908506219","TaskStatus":"COMPLETED","Result":{"Transcription":"https://prod-tingwu-paas-common-beijing.oss-cn-beijing.aliyuncs.com/tingwu/output/1171512458371407/5de301246fac411b8cc2bec2b2388d6b/5de301246fac411b8cc2bec2b2388d6b_Transcription_20240412155610.json?Expires=1715500695&OSSAccessKeyId=LTAI5tMzZ1D4o1drkJN1TfCr&Signature=p8ecCBYeWvPaMzkwN13rz1EL9Ps%3D"}},"Message":"success","RequestId":"53E7CFC5-4B3F-5B36-8EB0-64DCB78F684D"}
