下載 apk 並打開

１.安裝

cordova plugin add cordova-plugin-file-transfer
cordova plugin add cordova-plugin-file-opener2

２.下載.apk

var ft = new FileTransfer();
//監聽下載進度
ft.onprogress = function (e) {
  if (e.lengthComputable) {
    var progress = e.loaded / e.total * 100;
    $("#progress").css({ "width": progress + "%" });
    $("#progress").html(progress + "%");
  }
}
ft.download(zyd.openApp._downloadUrl, filePath, function (entry) {
  console.log('下載成功');
  console.info(JSON.stringify(entry));
  console.log('文件位置：' + entry.toURL());
  // 打開apk安裝包
  cordova.plugins.fileOpener2.open(
    entry.toURL(), 'application/vnd.android.package-archive', {
    error: function (e) {
      alert('失敗status:' + JSON.stringify(e) + " 路徑：" + entry.toURL())
    },
    success: function () {
      alert("安裝完成後請重新打開。");
    }
  });

}, function (err) {
  console.log("下載失敗！");
  console.info(JSON.stringify(err));
}, null, {});

3. vue 使用

downloadApk(url) {
  const fileTransfer = new FileTransfer()
  const uri = encodeURI(url)
  const fileURL = 'cdvfile://localhost/temporary/update.apk'
  fileTransfer.onprogress = (e) => {
    if (e.lengthComputable) {
      this.update.show = true
      let progress = Math.ceil(e.loaded / e.total * 100)
      if (progress < 100) {
        this.update.progress = progress;
      } else {
        this.update.progress = 100;
        this.update.show = false
      }
    }
  }
  fileTransfer.download(uri, fileURL,
    function (entry) {
      cordova.plugins.fileOpener2.open(
        entry.toURL(), 'application/vnd.android.package-archive', {
        error: function (e) {
          this.$tip("fail", `打開失敗，文件路徑：${entry.toURL()}`);
        },
        success: function () { }
      }
      )
    },
    function (error) {
      this.$tip("fail", "下載失敗");
    }
  )
}
