android - java.lang.NoSuchFieldError : org. apache.http.message.BasicHeaderValueFormatter.INSTANCE android

Question

尝试使用以下代码上传大型视频但出现此错误<java.lang.NoSuchFieldError: org.apache.http.message.BasicHeaderValueFormatter.INSTANCE>。我猜它的发生是由于多个类路径，但如何在 Eclipse 中纠正。为此，我使用了来自 http://hc.apache.org/downloads.cgi 的 jar 文件。仅包含 httpclient-4.4.jar、httpcore-4.4.jar、httpmime-4.4.jar来自链接。

public class MainActivity extends ActionBarActivity {
    int SELECT_VIDEO = 1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        Intent intent = new Intent();
        intent.setType("video/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent,"Select a Video "), SELECT_VIDEO);       
    }


    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_VIDEO) {
                System.out.println("SELECT_VIDEO");
                Uri selectedVideoUri = data.getData();
                String selectedPath = getPath(selectedVideoUri);
                System.out.println("SELECT_VIDEO Path : " + selectedPath);
                try {
                    uploadVideo(selectedPath);
                } catch (ParseException | IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }      
        }
    }

    private String getPath(Uri uri) {
        String[] projection = { MediaStore.Video.Media.DATA, MediaStore.Video.Media.SIZE, MediaStore.Video.Media.DURATION}; 
        Cursor cursor = managedQuery(uri, projection, null, null, null);
        cursor.moveToFirst(); 
        String filePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA));
        int fileSize = cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.SIZE));
        long duration = TimeUnit.MILLISECONDS.toSeconds(cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DURATION)));
         return filePath;
    }


    @SuppressWarnings("deprecation")
    private void uploadVideo(String videoPath) throws ParseException, IOException {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("URL");

        FileBody filebodyVideo = new FileBody(new File(videoPath));
        StringBody title = new StringBody("Filename: " + videoPath);
        StringBody description = new StringBody("This is a description of the video");

        MultipartEntity reqEntity = new MultipartEntity();
        reqEntity.addPart("videoFile", filebodyVideo);
        reqEntity.addPart("title", title);
        reqEntity.addPart("description", description);
        httppost.setEntity(reqEntity);

        // DEBUG
        System.out.println( "executing request " + httppost.getRequestLine( ) );
        HttpResponse response = httpclient.execute( httppost );
        HttpEntity resEntity = response.getEntity( );

        // DEBUG
        System.out.println( response.getStatusLine( ) );
        if (resEntity != null) {
          System.out.println( EntityUtils.toString( resEntity ) );
        } // end if

        if (resEntity != null) {
          resEntity.consumeContent( );
        } // end if

        httpclient.getConnectionManager( ).shutdown( );
    } // end of uploadVideo( )

}

Answer 1

您的代码可以摆脱 MultipartEntity 的弃用代码并使用 MultipartEntityBuilder。但是这里涉及的具体问题是核心Android库与新添加的库冲突。现在也有可用的 Maven 存储库。您可以将以下代码包含到以下文件中:

build.grade (Module:app)

compile('org.apache.httpcomponents:httpmime:4.3.6') {
    exclude module: 'httpclient'
}
compile 'org.apache.httpcomponents:httpclient-android:4.3.5'

解决方法非常简单。感谢oleg寻找答案 here
