Android版本更新

引入库

compile 'com.allenliu.versionchecklib:library:2.0.0'

//用于标记是否正在版本更新
private static boolean upAppFirst = true;
联网获取服务器版本信息

 //版本更新
    private void checkVersion() {
        if (upAppFirst) {
            httpManager.doHttpDeal(new CheackVersionApi());//网络请求
        } else {
            ToastUtils.show(getActivity(), "正在进行版本更新...");
        }
    }

在获取数据成功的时候，获取本地版本信息，判断是否需要进行更新,这里就不用写了

if (isNeedUpdate) {
            if (!TextUtils.isEmpty(resultBean.getDownloadUrl())) {
                builder = AllenVersionChecker
                        .getInstance()
                        .requestVersion()
                        .setRequestUrl("https://www.baidu.com")
                        .request(new RequestVersionListener() {
                            @Nullable
                            @Override
                            public UIData onRequestVersionSuccess(String result) {
                                UIData uiData = UIData.create();
                                uiData.setTitle(getString(R.string.app_name));
                                uiData.setDownloadUrl(resultBean.getDownloadUrl());
                                uiData.setContent(getString(R.string.updatecontent));
                                return uiData;
                            }

                            @Override
                            public void onRequestVersionFailure(String message) {
                                Toast.makeText(getActivity(), "request failed", Toast.LENGTH_SHORT).show();
                                upAppFirst = true;
                                ToastUtils.show(getActivity(), "下载地址不可用，请联系客服");
                            }
                        });
                builder.setShowDownloadingDialog(false);
                builder.setNotificationBuilder(createCustomNotification());
                builder.setDownloadAPKPath(Environment.getExternalStorageDirectory().getAbsolutePath() + "/lifeCrys/");
                builder.setApkDownloadListener(new APKDownloadListener() {
                    @Override
                    public void onDownloading(int progress) {
                        if (upAppFirst) {
                            upAppFirst = false;
                            ToastUtils.show(getActivity(), "正在更新...");
                        }
                    }

                    @Override
                    public void onDownloadSuccess(File file) {
                        upAppFirst = true;
                    }

                    @Override
                    public void onDownloadFail() {
                        upAppFirst = true;
                        ToastUtils.show(getActivity(), "下载地址不可用，请联系客服");
                    }
                });
                builder.excuteMission(getActivity());

            } else {
                ToastUtils.show(getActivity(), "下载地址不可用，请联系客服");
            }
        } else {
            ToastUtils.show(getActivity(), "当前版本已经是最新的版本了");
        }
    }

通知栏显示状态

 private NotificationBuilder createCustomNotification() {
      return NotificationBuilder.create()
            .setRingtone(true)
            .setIcon(R.mipmap.logo)
            .setTicker("custom_ticker")
            .setContentTitle(getString(R.string.update))
            .setContentText(getString(R.string.custom_content_text));
}
