Java 当api 24和api 25中有新版本可用时，Android会以编程方式更新应用程序

我试图用牛轧糖更新我的应用程序，但我不能，我得到以下错误

代码 错误

---

请帮我解决这个问题

我终于找到了解决方案

long referenceId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if(downloadReference == referenceId) {
Timber.d("Downloading of the new app version complete");
//start the installation of the latest version
Intent installIntent = new Intent(Intent.ACTION_VIEW);
installIntent.setDataAndType(dm.getUriForDownloadedFile(downloadReference),
                                    "application/vnd.android.package-archive")
installIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(installIntent);

那应该没问题。您可以尝试删除

FLAG\u ACTIVITY\u NEW\u TASK

，看看这是否有帮助。
