三星S8/S5/J2/Note3
正在Firebase Push Notification
成功应用程序被杀死,在后台或前台,
但Infinix Note 5 (Android One- Oreo)
和Oppo F9(Oreo)
如果应用程序被杀害没有得到推送通知,他们的工作很好,如果应用程序在背景或前景.
我经历了很多文章,这个和这个,提到中国手机有这个问题,并且用户方面有一些工作来使这些通知在他们的手机上工作.
但我想知道从开发方面是否有可能在每个Android设备上进行通知工作.
我的目标是API 27,这是我的代码

如果app被杀,Infinix Note 5(Android One-Oreo)和Oppo F9(Oreo)没有得到推送通知,如果应用程序处于后台或前台,它们可以正常工作.
当应用程序从最近的应用程序托盘中刷过你的应用程序终止时,中文ROM使用(氧气操作系统,MIUI等)(类似于强制停止).由于每个任务在后台运行,如服务,乔布斯被应用程序杀死.即便是高优先级的FCM也看不到中文ROM的日光
实时问题:
1)您无法获取用户的位置.因此,如果取决于实时位置,任何应用都无法正常工作
2)您无法接收FCM高优先级通知
3)如果应用程序不在托盘中,则没有时间特定的任务/作业将执行...等等.
解
用户需要在app的设置中启用自动启动以保持后台服务/作业运行.默认情况下它是关闭的.要在我们可以使用的某些设备中执行此操作,
示例代码
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent();
String manufacturer = android.os.Build.MANUFACTURER;
switch (manufacturer) {
case "xiaomi":
intent.setComponent(new ComponentName("com.miui.securitycenter",
"com.miui.permcenter.autostart.AutoStartManagementActivity"));
break;
case "oppo":
intent.setComponent(new ComponentName("com.coloros.safecenter",
"com.coloros.safecenter.permission.startup.StartupAppListActivity"));
break;
case "vivo":
intent.setComponent(new ComponentName("com.vivo.permissionmanager",
"com.vivo.permissionmanager.activity.BgStartUpManagerActivity"));
break;
}
List<ResolveInfo> arrayList = getPackageManager().queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
if (arrayList.size() > 0) {
startActivity(intent);
}
}
}

这是所有中国设备的问题。一旦你杀死了应用程序......它会从内存中删除而不是所有活动......但对于其他设备制造商来说情况并非如此......他们不会删除该应用程序完全来自内存。我也遇到了小米设备的这个问题......他们可以选择锁定应用程序,即使应用程序被杀死以清除内存,也可以将应用程序保留在内存中
