我怎样才能做到这一点？必须有一种与Google Play沟通的方式。我浏览了很多博客。但是，没有找到任何解决方案。如果用户禁用了自动应用程序更新，这对开发人员来说可能是一个很棒的功能。我猜它是由应用程序本身控制的，而不是由Google Play控制的。我开发了一些应用程序，可以在启动时调用API来读取“最新”版本号以及该版本是否为“强制”更新，并将其与正在运行的应用程序版本进行比较。如果有新版本可用，则会向用户显示一个与您显示的对话框类似的对话框（尽管他们的对话框更好），提醒用户更新可用。如果更新是“强制”的，则消息会告诉他们在继续之前必须更新应用程序。如果他们单击更新，那么他们将被带到应用商店页面，在那里他们像往常一样开始下载更新，应用程序将退出。如果他们单击“关闭”，应用程序将退出。如果更新不是强制性的，则会询问他们是现在更新还是继续。如果他们单击更新，那么他们将被带到应用商店页面，在那里他们像往常一样开始下载更新，应用程序将退出。如果他们单击“继续”，那么他们将被带到应用程序的现有版本中
我不知道他们是如何管理后台下载，然后在退出应用程序之前启动应用程序更新的。这将非常好，但我们上面的方法也非常简单，为开发人员提供了很多功能。谷歌正在测试应用程序更新API的早期版本，如中所述
它现在只对一些早期测试合作伙伴可用，但最终应该对所有开发人员可用。请关注Android开发者博客和Play console中的公告。Android今天正式向所有人发布了应用内更新 更新： 在单个活动中处理即时和灵活的更新；科特林路

FakeAppUpdateManager官方文档：为了实现这一点，在接受的答案中引用的谷歌官方文档在语法上是不正确的。经过一些研究，我终于找到了正确的语法： 而不是：
// Creates an instance of the manager.
AppUpdateManager appUpdateManager = AppUpdateManagerFactory.create(context);
// Returns an intent object that you use to check for an update.
Task<AppUpdateInfo> appUpdateInfo = appUpdateManager.getAppUpdateInfo();
// Checks that the platform will allow the specified type of update.
if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
// For a flexible update, use AppUpdateType.FLEXIBLE
&& appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
// Request the update.
appUpdateManager.startUpdateFlowForResult(
// Pass the intent that is returned by 'getAppUpdateInfo()'.
appUpdateInfo,
// Or 'AppUpdateType.FLEXIBLE' for flexible updates.
AppUpdateType.IMMEDIATE,
// The current activity making the update request.
this,
// Include a request code to later monitor this update request.
MY_REQUEST_CODE);
}
@Override
protected void onDestroy() {
mAppUpdateManager.unregisterListener(installStateUpdatedListener);
super.onDestroy();
}
@Override
protected void onResume() {
try {
mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
if (appUpdateInfo.updateAvailability() ==
UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {
// If an in-app update is already running, resume the update.
try {
mAppUpdateManager.startUpdateFlowForResult(
appUpdateInfo,
inAppUpdateType,
this,
RC_APP_UPDATE);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
});
mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
//For flexible update
if (appUpdateInfo.installStatus() == InstallStatus.DOWNLOADED) {
popupSnackbarForCompleteUpdate();
}
});
} catch (Exception e) {
e.printStackTrace();
}
super.onResume();
}
//For Immediate
inAppUpdateType = AppUpdateType.IMMEDIATE; //1
inAppUpdate();
//For Flexible
inAppUpdateType = AppUpdateType.FLEXIBLE; //0
inAppUpdate();
尝试使用这些库，在这些库中只需几行代码即可实现
谢谢您抽出时间。我们可以在应用程序中轻松开发此功能。但是你必须把用户带到游戏商店。然而，如果你能猜到的话，Google Play也有一些回调。这就是为什么他们能够在下载完成时显示SnackBar。酷！Google Play似乎正在与选定的合作伙伴测试应用内更新API。想在它可用时查看它。。。它被称为应用程序内更新API，并由选定的合作伙伴进行测试。我也在等这个。不幸的是，谷歌喜欢发布需要很长时间才能发布的功能和产品。我正在运行一些测试，但似乎无法正常工作。我总是得到UpdateAvailability.UPDATE\u作为响应。有什么我遗漏的吗？@kevintresuelo我想你的应用应该发布在Play store上。对于测试，请降低版本
