【中文标题】启用 proguard 后 java.lang.NoSuchMethodError Org/apache/http/util/ByteArrayBuffer

【英文标题】：java.lang.NoSuchMethodError Lorg/apache/http/util/ByteArrayBuffer after enabling progurd

【问题描述】：

我的应用程序正在崩溃，如下面的日志所示。

我使用这些代码已经有一段时间了，但现在它突然崩溃了。

只有在我启用 progurd 时应用程序才会崩溃。如果不启用 progurd，它就可以工作

 java.lang.NoSuchMethodError: No virtual method g([BII)V in class Lorg/apache/http/util/ByteArrayBuffer; or its super classes (declaration of 'org.apache.http.util.ByteArrayBuffer' appears in /system/framework/org.apache.http.legacy.boot.jar)

这里是代码，我正在使用 volley 向服务器发送 Multipart 数据，应用程序在 mBuilder.build(); 上崩溃

public class BaseUploadHttpRequest<T> extends Request<T> 

    private static final int TIMEOUT_RETRY_POLICY = 15000;

    private static Map<String, String> mParams = new HashMap<String, String>();
    private static Map<String, File> mFiles = new HashMap<String, File>();



    private final Object deserializer;
    private final Class<T> clazz;
    private final Listener<T> listener;
    private MultipartEntityBuilder mBuilder = MultipartEntityBuilder.create();


    public BaseUploadHttpRequest(String url, Class<T> clazz, Map<String, String> params, Map<String, File> files, Listener<T> listener,
                                 ErrorListener errorListener, Object deserializer) 
        super(Method.POST, url, errorListener);
        setRetryPolicy(new DefaultRetryPolicy(
                TIMEOUT_RETRY_POLICY,
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
        this.clazz = clazz;
        this.listener = listener;
        this.deserializer = deserializer;
        mFiles.putAll(files);
        //mHeader.putAll(appendHeader);
        mParams.putAll(params);
        buildMultipartEntity();
    

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError 
        Map<String, String> headers = super.getHeaders();

        if (headers == null
                || headers.equals(Collections.emptyMap())) 
            headers = new HashMap<String, String>();
        

        headers.put("Accept", "application/json");

        return headers;
    

    private void buildMultipartEntity() 
        int count = 0;
        for (String key : mFiles.keySet()) 
            File file = mFiles.get(key);
            String fileName = file.getName();
            mBuilder.addBinaryBody(key, file, ContentType.create("image/jpeg"), fileName);
        

        try 
            for (String key : mParams.keySet()) 
                mBuilder.addTextBody(key, mParams.get(key));
            
         catch (Exception e) 
            VolleyLog.e("Exception");
        
        mBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        mBuilder.setLaxMode().setBoundary("xx").setCharset(Charset.forName("UTF-8"));
    

    @Override
    public String getBodyContentType() 
        return mBuilder.build().getContentType().getValue();
    

    @Override
    public byte[] getBody() throws AuthFailureError 
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        try 
           HttpEntity httpEntity= mBuilder.build(); /// application crash our here
           httpEntity.writeTo(bos);
         catch (IOException e) 
            VolleyLog.e("IOException writing to ByteArrayOutputStream bos, building the multipart request.");
        

        return bos.toByteArray();
    

    @Override
    protected void deliverResponse(T response) 
        listener.onResponse(response);
    

我正在使用implementation files('libs/httpclient-osgi-4.3.jar') 和截击implementation 'com.android.volley:volley:1.1.0'

【参考方案1】：

试试这个。 Proguard 应该忽略外部库，因为外部库已经被压缩。

有时，再次重新压缩外部库时，proguard 可能会导致错误

-keep class org.apache.**  *; 

在上面添加到下面

-dontwarn org.apache.http.**
-keep class org.apache.**  *;  // add it here

参考：How to make Proguard ignore external libraries?

【参考方案2】：

首先你将 httpclient-osgi-4.3.jar 从here更新为最新的

然后修改progurd规则以保持类如下

-keep class org.apache.**  *;
