问题 I want to access getFilesDir() which is a context method. Is there any way to access it similarly to the way I access external-storage? Environment.getExternalStorageDirectory(); meaning as an environment variable? Maybe application static context? as I want to call this from a non-context class (same app service, but not an activity). 回答1: It's not possible. Context.getFilesDir() returns a path that is bound to your package and the Context is required to access the package name. Environment

I want to save in my app an imageFile I want "Google+ cropper app" to use it. But the later opens another image. I guess it's permissions issue. In my code i save here: Is this external storage? Environment.getExternalStorageDirectory().getAbsolutePath() which returns: /storage/emulated/0/myApp/file1.tmp using adb shell is see the file is actually saved in: /storage/emulated/legacy/myApp/file1.tmp why is the difference? should i use this place instead? Is this external storage? getAppContext().getFilesDir().getParent() which returns: `data/data/myApp' Squonk Historically the difference between

Why would you ever use asp.net's ViewState storage object over the Session storage object?

雨燕双飞 提交于 2019-11-29 21:05:51
Other than because session storage is session-global to more than one page, why would you ever want to use the viewstate to hold values? It seems kind of ridiculous to send any kind of information other than a few small query string like values, back and forth from the client to server. I mean what a waste of bandwidth(!), simply for storage purposes. The session, while global across multiple pages, seems like a completely superior alternative to the viewstate. Especially with asp.net ajax controls and variants, the viewstate could quickly become bloated tracking the various states and

问题 I see in the docs how do do this for pods, but I want to use a replication controller to manage my pods, ensuring that there is always one up at all times. How can I define a replication controller where the pod being run has a persistent volume? How is this related to Kubernetes persistentVolumes and persistentVolumeClaims? 回答1: Using a persistent volume in a Replication Controller works great for shared storage. You include a persistentVolumeClaim in the RC's pod template. Each pod will use

How to synchronize HTML5 local/webStorage and server-side storage? [duplicate]

Possible Duplicate: Best way to synchronize local HTML5 DB (WebSQL Storage, SQLite) with a server (2 way sync) I'm currently seeking solutions for transparently and automatically synchronizing and replicating across the client-side HTML5 localStorage or web storage and (maybe multiple) server-side storage(s) (the only requirement here that it should be simple and affordable to install on a regular hosting service). So do you have any experience with such libraries/technologies that offer data storage which automate the client-server storage synchronization and allow data to be available either

How can I save some user data locally on my Xamarin Forms app?

I have a simple Xamarin Forms app. I've now got a simple POCO object (eg. User instance or an list of the most recent tweets or orders or whatever). How can I store this object locally to the device? Lets imagine I serialize it as JSON. Also, how secure is this data? Is it part of Keychains, etc? Auto backed up? cheers! You have a couple options. SQLite. This option is cross-platform and works well if you have a lot of data. You get the added bonus of transaction support and async support as well. EDIT : In the past I suggested using SQLite.Net-PCL . Due to issues involving Android 7.0 support

Should I obfuscate OAuth consumer secret stored by Android app?

自闭症网瘾萝莉.ら 提交于 2019-11-29 20:09:03
My Android app contains OAuth consumer secret for Twitter's API. At the moment it's in .properties file in plain text, so it takes zero effort for someone to look it up in APK. Should I take steps to obscure it (like, rot13 or stored in obfuscated Java code)? Or should I actually avoid doing any of that, as it would create false sense of security? How do people usually distribute/store OAuth secret in Android apps? How common it is for the secret to be stolen and abused? The real question is what does an attacker get from stealing it... You should do your best to protect secrets but at the end

Is InnoDB (MySQL 5.5.8) the right choice for multi-billion rows?

≯℡__Kan透↙ 提交于 2019-11-29 17:55:45
问题 So, one of my tables in MySQL which uses the InnoDB storage engine will contain multi-billion rows(with potentially no limit to how many will be inserted). Can you tell me what sort of optimizations i can do to help speed up things? Cause with a few million rows already, it will start getting slow. Of course if you suggest to use something else. The only options i have are PostgreSQL and Sqlite3. But I've been told that sqlite3 is not a good choice for that. As for postgresql, i have

pros and cons of db and ndb in google app engine

雨燕双飞 提交于 2019-11-29 16:55:19
问题 I have seen a little of this in stack overflow but I am wondering if there is any reason to use the DB entity model and what the specific pros and cons of using on or the other are. I have read the ndb is a little faster and that it helps with caching. They have a good bit of info in the docs but don't really straight out say that ndb is better. At least I haven't found that yet. 回答1: As far as I can tell ndb is an evolution of db, kept seperate to maintain compatability. Have a look at the
