4.4以下并没有提过从app跳转到应用通知设置页面的Action，可考虑跳转到应用详情页面,下面是直接跳转到应用通知设置的代码：
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { Intent intent = new Intent(); intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS"); intent.putExtra("app_package", getActivity().getPackageName()); intent.putExtra("app_uid", getActivity().getApplicationInfo().uid); startActivity(intent); } else if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.KITKAT) { Intent intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); intent.addCategory(Intent.CATEGORY_DEFAULT); intent.setData(Uri.parse("package:" + getActivity().getPackageName())); startActivity(intent); }
跳转到应用详情页面的代码如下：
Intent localIntent = new Intent(); localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); if (Build.VERSION.SDK_INT >= 9) { localIntent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS"); localIntent.setData(Uri.fromParts("package", getActivity().getPackageName(), null)); } else if (Build.VERSION.SDK_INT <= 8) { localIntent.setAction(Intent.ACTION_VIEW); localIntent.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails"); localIntent.putExtra("com.android.settings.ApplicationPkgName", getActivity().getPackageName()); } startActivity(localIntent);
对于检测app是否开启通知，同样是针对4.4以上的系统才有效:
NotificationManagerCompat manager = NotificationManagerCompat.from(App.getInstance().getContext()); boolean isOpened = manager.areNotificationsEnabled();
4.4以下调用该方法并不会出错，只是全部返回true,默认开启状态
---------
Android判断APP通知权限是否打开
场景：判断用户是否屏蔽了应用的推送权限
NotificationManagerCompat.from(context).areNotificationsEnabled()
