第三方app版本更新

1.第三方app库:

https://github.com/WVector/AppUpdate、

引用:

api 'com.qianwen:update-app:3.5.2'

2.可在主页中请求接口判断是否要更新:

ApkUpdateUtils.appUpdate(mActivity);

5.自定义VersionDialog (含有非强制更新,强制更新一些列操作,后台返回的是markdown格式,结合需求自己定义)

public class VersionDialog extends Dialog {

        super(context);
        this.appVersionBean = appVersionBean;
        isForceUpdate = appVersionBean.getIs_forced() > 0;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.custom_dialog_two_layout);
        TextView tvTitle = (TextView) findViewById(com.ls.commonlibrary.R.id.tv_title);
        final MarkdownView mdMsg = (MarkdownView) findViewById(com.ls.commonlibrary.R.id.md_msg);
        TextView tvAbord = (TextView) findViewById(com.ls.commonlibrary.R.id.tv_abord);
        tvInstall = (TextView) findViewById(com.ls.commonlibrary.R.id.versionchecklib_version_dialog_commit);

        ImageView close = (ImageView) findViewById(com.ls.commonlibrary.R.id.img_close);
        ll_progress = (LinearLayout) findViewById(R.id.ll_progress);
        tv_progress = (TextView) findViewById(R.id.tv_progress);
        pb = (ProgressBar) findViewById(R.id.pb);
        //可以使用之前从service传过来的一些参数比如:title。msg,downloadurl,parambundle
        tvTitle.setText("V" + appVersionBean.getVersion() + "版本更新");
        InternalStyleSheet css = new Github();

        css.addRule("a", "font-weight: bold");
        mdMsg.addStyleSheet(css);
