android 8.0后台运行限制

android 8.0后新加的后台运行限制权限能在代码中设置吗?怎么设置,请指教.

在android 有一个配置文件AndroidManifest.xml，里面 可以系统权限

很简单，使用startForeground将后台服务改为前台服务就可以了。

private void makeForegroundService() {
        Intent notificationIntent = new Intent(this, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationChannel channel;
        String channelId;

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            channelId = "channel";
            channel = new NotificationChannel(channelId, "MainActivity", NotificationManager.IMPORTANCE_NONE);
            if (notificationManager != null) {
                notificationManager.createNotificationChannel(channel);
            }
        } else {
            channelId = null;
        }

        Notification notification = new Notification.Builder(this, channelId).setContentTitle("Title").setContentText("ContentMessage").setContentIntent(pendingIntent).build();
        startForeground(SYSTEM_FIXED_SERVICE_ID, notification);
    }
