后台服务在小米和 Oppo 中被限制

Question

我们正在前台服务中使用 MQTT 运行开发应用程序。问题出在小米 Redmi Note 7 上，在我们终止应用程序后服务被终止，但在其他品牌上它工作正常。我没有在 Oppo 和 Vivo 上测试该应用程序，但在我搜索时它们也有问题。在服务的 onCreate 方法中，我调用了 startForeground(NOTIFICATION_ID, notification) 并且我在清单中的服务声明是这样的

<service
    android:name=".service.mqtt.MqttService"
    android:enabled="true"
    android:exported="false"
    android:foregroundServiceType="location" />

我也将 foregroundServiceType 更改为 connectedDevice|dataSync|mediaPlayback 并添加了 android:stopWithTask="false" 并在 onStartCommand 服务方法中返回了 START_STICKY 但仍然无法正常工作。

终于找到答案了

private static final Intent[] POWERMANAGER_INTENTS = {
    new Intent().setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity")),
    new Intent().setComponent(new ComponentName("com.letv.android.letvsafe", "com.letv.android.letvsafe.AutobootManageActivity")),
    new Intent().setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.startupmgr.ui.StartupNormalAppListActivity")),
    new Intent().setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.optimize.process.ProtectActivity")),
    new Intent().setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.appcontrol.activity.StartupAppControlActivity")),
    new Intent().setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.permission.startup.StartupAppListActivity")),
    new Intent().setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.startupapp.StartupAppListActivity")),
    new Intent().setComponent(new ComponentName("com.oppo.safe", "com.oppo.safe.permission.startup.StartupAppListActivity")),
    new Intent().setComponent(new ComponentName("com.iqoo.secure", "com.iqoo.secure.ui.phoneoptimize.AddWhiteListActivity")),
    new Intent().setComponent(new ComponentName("com.iqoo.secure", "com.iqoo.secure.ui.phoneoptimize.BgStartUpManager")),
    new Intent().setComponent(new ComponentName("com.vivo.permissionmanager", "com.vivo.permissionmanager.activity.BgStartUpManagerActivity")),
    new Intent().setComponent(new ComponentName("com.samsung.android.lool", "com.samsung.android.sm.ui.battery.BatteryActivity")),
    new Intent().setComponent(new ComponentName("com.htc.pitroad", "com.htc.pitroad.landingpage.activity.LandingPageActivity")),
    new Intent().setComponent(new ComponentName("com.asus.mobilemanager", "com.asus.mobilemanager.MainActivity"))
};



for (Intent intent : POWERMANAGER_INTENTS)
    if (getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY) != null) {
            // show dialog to ask user action
        break;
}

编辑： 还有一个问题是检查用户是否启用了自动启动。在我搜索时，目前没有可用的解决方案。所以我自己设计了一个解决方案。我创建了一个工作人员，它将每 25 分钟在首选项中节省系统时间。每次打开应用程序时，我都会检查首选项，如果距离保存时间超过 30 分钟，则意味着工作人员无法完成工作，因此可能用户上次没有启用自动启动，必须再次提示。

class BackgroundCheckWorker(val appContext: Context, val workerParams: WorkerParameters) :
Worker(appContext, workerParams), KoinComponent {


override fun doWork(): Result {
    val pref = appContext.getSharedPreferences(PermissionHandler.AUTO_START_PREF, Context.MODE_PRIVATE)
    val editor = pref.edit()
    editor.putString(AUTO_START_PREF_KEY, Calendar.getInstance().time.toString())
    editor.apply()
    return Result.success()
}
}

在 splash 中我调用这个函数：

fun requestUnrestrictedBackgroundService(context: Activity): Boolean {
            val pref = context.getSharedPreferences(AUTO_START_PREF, Context.MODE_PRIVATE)
            var updated = false
            val lastUpdate = pref.getString(AUTO_START_PREF_KEY, "")
            updated = if (lastUpdate == null || lastUpdate == "") {
                val editor = pref.edit()
                editor.putString(AUTO_START_PREF_KEY, Calendar.getInstance().time.toString())
                editor.apply()
                false
            } else lastUpdate != "" &&
                    DateUtil.minAgo(lastUpdate) <= 30
            if (!updated) {
                for (intent in POWERMANAGER_INTENTS)
                    if (context.packageManager.resolveActivity(
                            intent,
                            PackageManager.MATCH_DEFAULT_ONLY
                        ) != null
                    ) {
                            val dialog = AlertDialog.Builder(context)
                            dialog.setMessage("On this device you must allow us to run services in background")
                                .setPositiveButton("Yes") { paramDialogInterface, paramInt ->
                                    val editor = pref.edit()
                                    editor.putString(AUTO_START_PREF_KEY, Calendar.getInstance().time.toString())
                                    editor.apply()
                                    context.startActivityForResult(intent, 1234)
                                }
                                .setNegativeButton("Cancel") { paramDialogInterface, paramInt -> context.finish() }
                            dialog.show()
                            return false
                    }
            }
            return true
        }
