安卓下载文件并使用其他app发送

  1. 下载文件
    集成xhttp2
api 'com.github.xuexiangjys:XHttp2:1.0.0'

application初始化xhttp2

XHttpSDK.init(getApplication());

下载文件

private fun downLoadFile() {
        val wait = WaitDialog.show(context,"正在生成")
        //2.直接下载方式
        val savePath = AppTypeUtil.getAppRootDir()+"/down_export"
        val saveName = "/ceshi.zip"
        XHttpSDK.setBaseUrl("https://img-lanjiyin.oss-cn-beijing.aliyuncs.com")
        XHttp.downLoad(saveName)
            .params(WebConstants.getHttpParams(hashMapOf()))
            .savePath(savePath)
            .saveName("export.zip")
            .execute(object: DownloadProgressCallBack(){
                override fun update(
                    downLoadSize: Long,
                    totalSize: Long,
                    done: Boolean
                ) {
                    wait.message = "正在下载 ${downLoadSize*100/totalSize}%"

                    LogUtils.d("huanghai-export",this,"ExportHelper.update","downLoadSize:$downLoadSize","totalSize:$totalSize","down:$done")
                }

                override fun onComplete(path: String?) {
                    wait.doDismiss()
                    LogUtils.d("huanghai-export",this,"ExportHelper.onComplete","path",path)
                    ToastUtils.showShort("文件保存在:${savePath+saveName}")
                    //通过其他应用发送
                    path?.let {
                        sendFileByOtherApplication(context,it)
//                                                openFileByOtherApplication(context,it)
                    }
                }

                override fun onError(e: ApiException?) {
                    wait.doDismiss()
                    e?.printStackTrace()
                }

                override fun onStart() {
                    wait.message = "正在下载 0%"
                    LogUtils.d("huanghai-export",this,"ExportHelper.onStart")
                }

            })
    }
  1. 使用其他app发送文件
fun sendFileByOtherApplication(context:Context,path:String){
    val intent = Intent(Intent.ACTION_SEND);
    intent.setType(MapTable.getMIMEType(path))
    intent.putExtra(Intent.EXTRA_STREAM, FileUtils.getUriForFile(File(path)));

    try {
        context.startActivity(Intent.createChooser(intent,"分享文件"));
    }catch (e:Exception){
        e.printStackTrace()
    }
}

映射 MapTable

package com.lanjiyin.lib_model.util;

public class MapTable {
    /**
     * -- MIME 列表 --
     */
    public static final String[][] MIME_MapTable = {
                // --{后缀名, MIME类型}   --
