Android App升级的方案

一、介绍一下服务器的操作。

1.看看数据库表。

注意到force这参数，force=1，强制升级，force=0，自愿升级。

二、自选升级。

1.调用升级接口，查看version的版本号，如果版本号大于当前app的版本号，那么就触发显示升级对话框。代码如下：

/** * 联网获取更新数据 */ private void getUpdateInfo(){ Log.e("TAG", "FolderActivity getUpdateInfo"); Map<String,String> map=new HashMap<>(); map.put("flag","1"); CommonUtils.showProgress(this,"正在检查更新，请稍等..."); CommonUtils.Get(NetUrl.UPDATE_URL, map, new MyCallBack<String>() { @Override public void onSuccess(String result) { //if(result.contains("data")){ CacheUtils.getInstance(MainActivity.this).getValue(NetUrl.UPDATE_URL, result); CommonUtils.cancelProgress(); CacheUtils.getInstance(MainActivity.this).putValue(NetUrl.UPDATE_URL,result); parseUpdateData(result); } @Override public void onError(Throwable ex, boolean isOnCallback) { CommonUtils.cancelProgress(); CommonUtils.showToast(MainActivity.this,getResources().getString(R.string.get_error_text)); } }); } /** * 解析更新数据 * @param result */ private void parseUpdateData(String result) { UpdateInfoBean updateInfoBean = CUtils.getGson().fromJson(result, UpdateInfoBean.class); UpdateInfoBean.DataBean data = updateInfoBean.getData(); double versionName = Double.parseDouble(CommonUtils.getAppVersionName(this)); Log.e("TAG", ""+versionName+":"+data.getVersion()); if(versionName<data.getVersion()){ showUpdateDialog(); }else{ CommonUtils.showToast(this,"当前已经是最新版本！"); } } /** * 显示更新的对话框 */ private void showUpdateDialog() { Intent intent = new Intent(this, DownloadActivity.class); startActivity(intent); }

升级对话框如图：

2.在升级对话框中，点击立刻更新，会在后台的通知栏中更新，退出，可以正常退出。代码需要重新写了个service在后台运行。代码和截图如下，注意service要在配置文件中注册。

public class DownLoadService extends Service { private static final String BASE_PATH = Environment.getExternalStorageDirectory().getPath() + File.separator; private String path=BASE_PATH+"hrobbie"+"/hrobbie.apk"; private Notification.Builder builder; private NotificationManager notificationManager; private int number; private Notification build; @Nullable @Override public IBinder onBind(Intent intent) { return null; } @Override public void onCreate() { super.onCreate(); notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); builder = new Notification.Builder(DownLoadService.this); } @Override public int onStartCommand(Intent intent, final int flags, int startId) { number = startId; String download_url = intent.getStringExtra("download_url"); //downloadFile(download_url); Log.e("TAG", "DownloadService download_url="+download_url); Log.e("TAG", "DownloadService path="+path); builder.setSmallIcon(R.mipmap.ic_launcher).setContentTitle("一款应用正在下载0%").setWhen(System.currentTimeMillis()) .setPriority(Notification.PRIORITY_MAX).setTicker("一款应用下载").setOngoing(false).setAutoCancel(true) .setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0)); downloadFile(download_url); return super.onStartCommand(intent, flags, startId); } private void downloadFile(String download_url) { RequestParams requestParams = new RequestParams(download_url); requestParams.setAutoResume(true); //requestParams.setAutoRename(true);//断点下载 requestParams.setSaveFilePath(path); x.http().get(requestParams, new Callback.ProgressCallback<File>() { @Override public void onWaiting() { } @Override public void onStarted() { } @Override public void onLoading(long total, long current, boolean isDownloading) { builder.setContentTitle("一款应用正在下载"+(int)((double)current/total*100)+"%").setProgress((int)total,(int)current,false); send(); } @Override public void onSuccess(File result) { builder.setContentTitle("一款应用下载完成100%").setProgress(100, 100, false); send(); openFile(result); } @Override public void onError(Throwable ex, boolean isOnCallback) { Toast.makeText(DownLoadService.this,"下载失败，请检查网络和SD卡",Toast.LENGTH_SHORT).show(); //CommonUtil.showToast(DownLoadService.this,"下载失败，请检查网络和SD卡"); } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { } }); } //打开APK程序代码 private void openFile(File file) { // TODO Auto-generated method stub Log.e("OpenFile", file.getName()); Intent intent = new Intent(); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setAction(Intent.ACTION_VIEW); intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive"); startActivity(intent); } private void send(){ build = builder.build(); notificationManager.notify(number, build); } }

如图：

三、强制升级。

1.当收到服务器的force=1时，需要强制升级，这个时候，需要展示的界面如下：

2.点击立刻更新，会出现一个progressBar进行更新，如图：

3.如果此时强制退出，要销毁app，用的方法，代码如下：

private long curMillios = 0; private boolean showExitToast(){ long time = System.currentTimeMillis(); if (time - curMillios < 2000){ return true; } curMillios = time; return false; } @Override public void onBackPressed() { // TODO Auto-generated method stub //super.onBackPressed(); if(force==0){ finish(); }else{ if(showExitToast()){ /** * 关闭整个程序 */ ExitAppliation.getInstance().exit(); // //finish(); System.exit(0); }else{ CommonUtils.showToast(this,"再点击一次退出！"); } } }
