App启动广告

需求:

App启动的时候获得广告图片链接，如果已经存在，判断是否和本地的相同，不相同才去下载到本地。

流程图：

这些都在广告页的前一个页面操作（logo页或者Application）

        super.initView();

        checkAdUrl();

        jump();

    }

    private void checkAdUrl() {

        AdAPI.getAd(new BaseCallBack<AdResponseEntity>() {

            @Override

            public void onSuccess(Response<AdResponseEntity> response) {

                AdResponseEntity.Data data = response.body().getData();

                if (null == data) {

                    return;

                }

                String url = data.getUrl();

                if (TextUtils.isEmpty(url)) {

                    return;

                }

                String localAd = UserData.getAdBitmap();

                if (!TextUtils.isEmpty(localAd)) {

                    String urlFileName = url.substring(url.lastIndexOf("/") + 1);

                    String localFileName = localAd.substring(localAd.lastIndexOf("/") + 1);

                    if (urlFileName.equals(localFileName)) {

                        return;

                    }

                }

                SplashImgDownLoader.downLoad(url);

            }

        });

    }

    private void jump() {

        final Timer timer = new Timer();

        timer.schedule(new TimerTask() {

            @Override

            public void run() {

                if (null != timer) {

                    timer.cancel();

                    startActivity(new Intent(LogoActivity.this, SplashActivity.class));

                    finish();

                }

            }

        }, 1000);

    }

}

public class SplashImgDownLoader {

    public static void downLoad(String url) {

        String fileName = url.substring(url.lastIndexOf("/") + 1);

        String filePath = PathUtil.getInstance().getImagePath() + File.separator + fileName;

        BaseDownloadTask task = FileDownloader.getImpl().create(url).setPath(filePath).setListener(new FileDownloadListener() {

            @Override

            protected void pending(BaseDownloadTask task, int soFarBytes, int totalBytes) {

            }

            @Override

            protected void progress(BaseDownloadTask task, int soFarBytes, int totalBytes) {

            }

            @Override

            protected void completed(BaseDownloadTask task) {

                UserData.saveAdBitmap(task.getPath());

            }

            @Override

            protected void paused(BaseDownloadTask task, int soFarBytes, int totalBytes) {

            }

            @Override

            protected void error(BaseDownloadTask task, Throwable e) {

            }

            @Override

            protected void warn(BaseDownloadTask task) {

            }

        });

        task.start();

    }

}

然后，广告页只需要去本地拿地址然后加载就可以了
