一.下载文件

String apkName = TimeUtil.getSystem() + ".apk";//下载APK的名字，目前名字暂定为时间,等和后台确认协议后再修改        WaitDialog.Builder builder = new WaitDialog.Builder(this).setMessage("准备下载");        BaseDialog dialog = builder.show();        String url = "https://pack.qiyutianxia.com/gamepacks/S-wxcqbfb.apk";//一个可以下载APK测试网址        OkGo.
   
    get(url).tag(this).execute(new FileCallback(DirKeys.DIR_APP_UPDATE, apkName) {            @Override            public void onSuccess(Response
    
      response) {                builder.setMessage("下载完成");                dialog.dismiss();                /*下载完成后直接安装*/                AppUtils.installApp(response.body());            }            @Override            public void onError(Response
     
       response) {                super.onError(response);                ToastUtils.error(getString(R.string.apkerror, response.message()));                dialog.dismiss();            }            @Override            public void downloadProgress(Progress progress) {                super.downloadProgress(progress);                builder.setMessage("下载进度\n" + progress.currentSize / BasicKeys.KB + "KB/" + progress.totalSize / BasicKeys.KB + "KB");            }        });
     
    
   

二.BasicKeys

public class BasicKeys {    /******************** 存储相关常量 ********************/    /**     * Byte与Byte的倍数     */    public static final int BYTE = 1;    /**     * KB与Byte的倍数     */    public static final int KB = 1024;    /**     * MB与Byte的倍数     */    public static final int MB = 1048576;    /**     * GB与Byte的倍数     */    public static final int GB = 1073741824;    /**     * 毫秒与毫秒的倍数     */    public static final int MSEC = 1;    /******************** 时间相关常量 ********************/    /**     * 秒与毫秒的倍数     */    public static final int SEC = 1000;    /**     * 分与毫秒的倍数     */    public static final int MIN = 60000;    /**     * 时与毫秒的倍数     */    public static final int HOUR = 3600000;    /**     * 天与毫秒的倍数     */    public static final int DAY = 86400000;    /******************** 常量 ********************/    public static final int KEY_0 = 0;    public static final int KEY_1 = 1;    public static final int KEY_2 = 2;    public static final int KEY_3 = 3;    public static final int KEY_4 = 4;    public static final int KEY_5 = 5;    public static final int KEY_6 = 6;    public static final int KEY_7 = 7;    public static final int KEY_8 = 8;    public static final int KEY_9 = 9;    public static final int KEY_10 = 10;    public static final int KEY_11 = 11;    public static final int KEY_12 = 12;    public static final int KEY_13 = 13;    public static final int KEY_14 = 14;    public static final int KEY_15 = 15;    public static final int KEY_16 = 16;    public static final int KEY_17 = 17;    public static final int KEY_18 = 18;    public static final int KEY_19 = 19;    public static final int KEY_20 = 20;    public static final int KEY_200 = 200;    public static final int KEY_500 = 500;    public static final int KEY_404 = 404;    public static final String KEY_NO_SPACE = "";    public static final String KEY_ONE_SPACE = " ";    public static final String KEY_SEPARATOR= "/";    public static final String KEY_NEXT= "\n";    public static final String KEY_QUESTION = "?";    public static final String KEY_AND = "&";    public static final String KEY_COLON= ": ";    public static final String KEY_EQUAL= "=";    public static final String KEY_UTF8= "UTF-8";    public static final String KEY_NULL= "数据为空";    public static final String KEY_USE_API= "调用网络接口";    public static final String KEY_NOT_EXIST= "不存在";    public static final String KEY_DATA_ERROR= "传入参数错误!";    public static final String KEY_EXCEPTION= "出现异常";    public static final String KEY_NOT_NET= "无网络";    public static final String KEY_ACTION_MAIN="android.intent.action.MAIN";    public static final String KEY_FILE = "file";    public static final String HTTP = "http://";    public static final String COLON = ":";    public static final String COMMA = ",";}

三.上传文件

实战：

WaitDialog.Builder builder = new WaitDialog.Builder(mActivity).setMessage("视频上传");        builder.show();        File file = new File(url);        if (mActivity instanceof InspectionActivity) {            InspectionActivity inspectionActivity = (InspectionActivity) mActivity;            lineNumber = inspectionActivity.getLineNumber();        }        OkGo.
   
    
     >post(Api.getuploadVideoUrl())                .params("file", file)                .params(Api.TEST_LINE_NUMBER, lineNumber)                // TODO: 2020-10-27 暂时写死，用于测试                .params(Api.SERIAL_NUMBER, "3604252010220002")                .params(Api.CUR_TEST_TIMES, "1")//                .params(Api.SERIAL_NUMBER, carInfo.getSerialNumber())//                .params(Api.CUR_TEST_TIMES, carInfo.getTestingTimes())                .params("item ", item.getCode())//视频代号                .execute(new JsonCallback
     
      
       >() {                    @Override                    public void TokenOut() {                    }                    @Override                    public void onSuccess(Response
       
        
         > response) { super.onSuccess(response); if (response.body().isSuccess()) { builder.setMessage("视频上传成功").dismiss(); item.setUrl(url); item.setUploadStatus(1); videoItemAdapter.notifyDataSetChanged(); } else { ToastUtils.error(getString(R.string.uploaderror, response.message())); builder.dismiss(); item.setUploadStatus(2); videoItemAdapter.notifyDataSetChanged(); } } @Override public void onError(Response
         
          
           > response) { super.onError(response); ToastUtils.error(getString(R.string.uploaderror, response.message())); builder.dismiss(); item.setUploadStatus(2); videoItemAdapter.notifyDataSetChanged(); } @Override public void uploadProgress(Progress progress) { super.uploadProgress(progress); //上传进度 builder.setMessage("上传进度\n" + progress.currentSize / BasicKeys.KB + "KB/" + progress.totalSize / BasicKeys.KB + "KB"); } });
