Android：检查我的应用程序是否可以运行背景活动

发布于 01-21 04:21 字数 700 浏览 5 评论 0原文

我有一个运行秒表服务的应用程序，然后在前景中运行该服务。
我有一个通知显示计时器，每秒更新。
该通知在我离开应用程序后停止更新30秒，我发现原因是我的设备的电池优化：
在我应用程序的系统设置中，有一个电池优化部分，其中包含一个称为的设置允许背景活动，可以打开或关闭。
我找到了2个线程（对线程1 和对线程2的答案）试图回答如何检查设置状态，并且两者都建议使用activitymanager.isbackgroundrestricter。
对我来说，它不起作用。设置是打开还是关闭，此功能返回false。
如何检查我的应用程序是否可以运行背景活动？

这是我手机中设置的照片（OnePlus 8T oxygenos 12）：

我看到它也对我不起作用。因此，您可以在我的git回购中看到我的两个课程更新贴上应用-30-S/71840843＃71840843“>我以前的答案。另外，我的回购链接是在这里。 Here you must see

在那里，我要求忽略电池优化许可，如果启用了电池，则可以正常工作或不启用，请征得该许可。

此外，您可以查看与 this 问题的答案的结果。

该代码：

String packageName = getPackageName();
        PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
if (!pm.isIgnoringBatteryOptimizations(packageName)) {
    Toast.makeText(this, "no allowed", Toast.LENGTH_SHORT).show();
    // it is not enabled. Ask the user to do so from the settings.
}else {
    Toast.makeText(this, "allowed", Toast.LENGTH_SHORT).show();
    // good news! It works fine even in the background.
}

并将用户带到此设置页面，基于此答案：

Intent notificationIntent = new Intent(Settings.ACTION_APPLICATION_SETTINGS);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0, notificationIntent, PendingIntent.FLAG_IMMUTABLE);
String expandedNotificationText = String.format("Background activity is restricted on this device.\nPlease allow it so we can post an active notification during work sessions.\n\nTo do so, click on the notification to go to\nApp management -> search for %s -> Battery Usage -> enable 'Allow background activity')", getString(R.string.app_name));
notificationBuilder.setContentIntent(pendingIntent)
    .setContentText("Background activity is restricted on this device.")
    .setStyle(new NotificationCompat.BigTextStyle().bigText(expandedNotificationText))

I see that it does not work for me also. So, you can see my two classes in my Git repo which I had also provided you within my previous answer. Also my repo link is here. Here you must see this in my AndroidManifest.xml and this method and this overridden method.

There I am asking for the ignore battery optimization permission and if it is enabled, it works fine or it if not enabled, asks for that permission.

Also, you can view the result in relation to this question's answer. This is the result

If that does not work, refer to this code:

String packageName = getPackageName();
        PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
if (!pm.isIgnoringBatteryOptimizations(packageName)) {
    Toast.makeText(this, "no allowed", Toast.LENGTH_SHORT).show();
    // it is not enabled. Ask the user to do so from the settings.
}else {
    Toast.makeText(this, "allowed", Toast.LENGTH_SHORT).show();
    // good news! It works fine even in the background.
}

And to take the user to this setting's page, based on this answer:

Intent notificationIntent = new Intent(Settings.ACTION_APPLICATION_SETTINGS);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0, notificationIntent, PendingIntent.FLAG_IMMUTABLE);
String expandedNotificationText = String.format("Background activity is restricted on this device.\nPlease allow it so we can post an active notification during work sessions.\n\nTo do so, click on the notification to go to\nApp management -> search for %s -> Battery Usage -> enable 'Allow background activity')", getString(R.string.app_name));
notificationBuilder.setContentIntent(pendingIntent)
    .setContentText("Background activity is restricted on this device.")
    .setStyle(new NotificationCompat.BigTextStyle().bigText(expandedNotificationText))
