Android 友盟 推送 通知栏权限 检查 & 开启

App 集成友盟 oppo和vivo会有推送的情况（oppo和vivo通知栏权限默认是关闭）。

MainActivity

if(!NotificationsUtils.isNotificationEnabled(this)) {
    NotificationsUtils.openPush(this);
}

NotificationsUtils

public class NotificationsUtils {
    public static boolean isNotificationEnabled(Context context) {
        return NotificationManagerCompat.from(context.getApplicationContext()).areNotificationsEnabled();
    }

    public static void openPush(Activity activity) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            //这种方案适用于 API 26, 即8.0（含8.0）以上可以用
            Intent intent = new Intent();
            intent.setAction(Settings.ACTION_APP_NOTIFICATION_SETTINGS);
            intent.putExtra(Settings.EXTRA_APP_PACKAGE, activity.getPackageName());
            intent.putExtra(Settings.EXTRA_CHANNEL_ID, activity.getApplicationInfo().uid);
            activity.startActivity(intent);
        } else {
            PermissionUtil.toPermissionSetting(activity);
        }
    }
}

PermissionUtil

public class PermissionUtil {
    /**
     * 跳转到权限设置
     *
     * @param activity
     */
    public static void toPermissionSetting(Activity activity) {
        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {
            toSystemConfig(activity);
        } else {
            try {
                toApplicationInfo(activity);
            } catch (Exception e) {
                e.printStackTrace();
                toSystemConfig(activity);
            }
        }
    }

    /**
     * 应用信息界面
     *
     * @param activity
     */
    public static void toApplicationInfo(Activity activity) {
        Intent localIntent = new Intent();
        localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        localIntent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        localIntent.setData(Uri.fromParts("package", activity.getPackageName(), null));
        activity.startActivity(localIntent);
    }

    /**
     * 系统设置界面
     *
     * @param activity
     */
    public static void toSystemConfig(Activity activity) {
        try {
            Intent intent = new Intent(Settings.ACTION_SETTINGS);
            activity.startActivity(intent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

以上是基本代码逻辑，其实这样还是有点问题的，现在是打开app如果没有通知栏权限就跳去设置页，最好给用户一个弹窗先提醒一下会比较好。不过有了上面核心代码想自定义也不会很难。
