1使用Rxjava2与retrofit2获取更新信息,调用loadUpdate()即可。

 private void loadUpdate(){
        ApiUtils.getTqgApi(ApiUrls.tqgApiUrl)
                .getUpdateInfo()
                .unsubscribeOn(Schedulers.io())
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<UpdateBean>() {
                    Disposable d;
                    @Override
                    public void onSubscribe(@NonNull Disposable d) {
                        this.d =d;
                    }

                    @Override
                    public void onNext(@NonNull UpdateBean updateBean) {
                        if (getVersionCode(getApplicationContext())<updateBean.getUpdate_ver_code()) {
                            if(update_switch) {
                                mCheckUpdateInfo = new CheckUpdateInfo();
                                mCheckUpdateInfo.setAppName(updateBean.getUpdate_app_name())
                                        // .setIsForceUpdate(1)//设置是否强制更新,该方法的参数只要和服务端商定好什么数字代表强制更新即可
                                        .setNewAppReleaseTime(updateBean.getUpdate_Time())//软件发布时间
                                        // .setNewAppSize(12.3f)//单位为M
                                        .setNewAppSize(Float.parseFloat(updateBean.getUpdate_app_size()))
                                        .setNewAppUrl(updateBean.getUpdate_url())
                                        .setNewAppVersionCode(updateBean.getUpdate_ver_code())//新app的VersionCode
                                        .setNewAppVersionName(updateBean.getUpdate_ver_name())
                                        .setNewAppUpdateDesc(updateBean.getUpdate_content());
                                forceUpdateDialogClick(updateBean.isIgnore_able());
                            }
                        }
                    }

                    @Override
                    public void onError(@NonNull Throwable e) {
                        onComplete();
                    }

                    @Override
                    public void onComplete() {
                        d.dispose();
                    }
                });
    }

 

    /**
     * setForce(true);
     * 强制更新,checkupdatelibrary中提供的默认强制更新Dialog,您完全可以自定义自己的Dialog,
     */
    public void forceUpdateDialogClick(boolean isForce ) {
        mForceUpdateDialog = new ForceUpdateDialog(MainActivity.this);
        mForceUpdateDialog.setForce(isForce);
        mForceUpdateDialog.setAppSize(mCheckUpdateInfo.getNewAppSize())
                .setDownloadUrl(mCheckUpdateInfo.getNewAppUrl())
                .setTitle(mCheckUpdateInfo.getAppName() + "有更新啦")
                .setReleaseTime(mCheckUpdateInfo.getNewAppReleaseTime())
                .setVersionName(mCheckUpdateInfo.getNewAppVersionName())
                .setUpdateDesc(mCheckUpdateInfo.getNewAppUpdateDesc())
                .setFileName("taoxiang.apk")
                .setFilePath(Environment.getExternalStorageDirectory().getPath() + "/checkupdatelib").show();
    }

 

    public int getVersionCode(Context context){
        PackageManager packageManager=context.getPackageManager();
        PackageInfo packageInfo;
        int versionCode = 0;
        try {
            packageInfo=packageManager.getPackageInfo(context.getPackageName(),0);
            versionCode=packageInfo.versionCode;
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return versionCode;
    }

服务端Json文件如下

{
    "update_url": "http://taoxiang.hwwwwh.cn/taoxiang.apk",
