android 版本跟新之打开下载好的

1.引入第三方库
https://github.com/WVector/AppUpdate

2.使用


public static void  onlyDownload(final String mApkFileUrl, final Activity context) {
   // Log.d(TAG, "onlyDownload() called with: view = [" + view + "]");
    UpdateAppBean updateAppBean = new UpdateAppBean();
    String   apkurl =mApkFileUrl;
    if (!apkurl.startsWith("http")){
        apkurl = "http://lbb.ty-eco.com/picture"+mApkFileUrl;
    }

    //设置 apk 的下载地址
    updateAppBean.setApkFileUrl(apkurl);

    String path = "";
    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED) || !Environment.isExternalStorageRemovable()) {
        try {
            path = context.getExternalCacheDir().getAbsolutePath();
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (TextUtils.isEmpty(path)) {
            path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getAbsolutePath();
        }
    } else {
        path = context.getCacheDir().getAbsolutePath();
    }

    //设置apk 的保存路径
    updateAppBean.setTargetPath(path);
    //实现网络接口，只实现下载就可以
    updateAppBean.setHttpManager(new UpdateAppHttpUtil());
    HProgressDialogUtils.showHorizontalProgressDialog(context, "下载进度", false);
    UpdateAppManager.download(context, updateAppBean, new DownloadService.DownloadCallback() {
        @Override
        public void onStart() {

            Log.d(TAG, "onStart() called");
        }

        @Override
        public void onProgress(float progress, long totalSize) {
            HProgressDialogUtils.setProgress(Math.round(progress));
            Log.d(TAG, "onProgress() called with: progress = [" + progress + "], totalSize = [" + totalSize + "]");

        }

        @Override
        public void setMax(long totalSize) {
            Log.d(TAG, "setMax() called with: totalSize = [" + totalSize + "]");
        }

        @Override
        public boolean onFinish(File file) {
            HProgressDialogUtils.cancel();
            Log.d(TAG, "onFinish() called with: file = [" + file.getAbsolutePath() + "]");
            return true;
        }

        @Override
        public void onError(String msg) {
            HProgressDialogUtils.cancel();
            Log.e(TAG, "onError() called with: msg = [" + msg + "]");
        }

        @Override
        public boolean onInstallAppAndAppOnForeground(File file) {
            Log.d(TAG, "onInstallAppAndAppOnForeground() called with: file = [" + file + "]");
            return false;
        }
    });
