【App启动广告】知识就是力量，时间就是生命。这篇文章主要讲述App启动广告相关的知识，希望能为你提供帮助。
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）

import android.content.Intent; import android.text.TextUtils; import com.xuehu365.xuehu.R; import com.xuehu365.xuehu.business.SplashImgDownLoader; import com.xuehu365.xuehu.data.UserData; import com.xuehu365.xuehu.model.response.AdResponseEntity; import com.xuehu365.xuehu.netinterface.AdAPI; import com.xuehu365.xuehu.netinterface.retrofit.BaseCallBack; import java.util.Timer; import java.util.TimerTask; import retrofit2.Response; public class LogoActivity extends BaseFragmentActivity {@Override protected Object getCotentView() { return R.layout.activity_logo; }@Override protected void initView() { super.initView(); checkAdUrl(); jump(); }private void checkAdUrl() { AdAPI.getAd(new BaseCallBack< AdResponseEntity> () { @Override public void onSuccess(Response< AdResponseEntity> response) { AdResponseEntity.Data data = https://www.songbingjia.com/android/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); } }

import com.liulishuo.filedownloader.BaseDownloadTask; import com.liulishuo.filedownloader.FileDownloadListener; import com.liulishuo.filedownloader.FileDownloader; import com.xuehu365.xuehu.data.UserData; import com.xuehu365.xuehu.utils.PathUtil; import java.io.File; /** * Created by Administrator on 2017/8/8. */ 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
