Android getbytes from file

So what do I do. I open my own written level editor on Unity, create some levels that gonna be custom afterwards, and save them to StreamingAssets I serialize a class that consists of arrays and some small vars.

Then I build the game and access those files whenever I need. Everything works fine on PC, but nothing happens on Android platform.

I checked File. Exists pathand it returned false however I'm not sure if it works correctly on Android. Some platforms like android do not give you direct access to the streaming assets directory. That's true. But persistantDataPath is for saving some data after the build and reading it afterwards. What I want to do is to save information about game levels themselves, not the player progress in them. This means that I have to have pre-written info files that I have to be able to read when I want to load level.

Even if I manage to copy level files into persistantDataPath, somehow, it is located on SD-card is it? That's what I don't want. I have no idea how to store level info in other way. To create hundreds of similar scenes is not what I would want to do.

Ah sorry I missread part of the initial question. But now that I have more of an idea of what you are trying, is there any specific reason that these level files you're saving at edit time need to be in streaming assets? Load instead of manually reading the files yourself? StreamingAssets is a folder that keeps files in it in the form they were created.

Not compressed, not converted into some other format etc. So I can access any file by its name. Can I do same thing with Resources folder? I know how to do it with sprites etc, but have no idea what to do with byte file. No file access is available on WebGL. Android uses a compressed. These platforms return a URL.

See the javadoc here: docs. If you're going to read the entire file in one hit, there is no need to wrap the FileInputStream in a BufferedInputStream -indeed doing so will use more memory and slow things down as the data will be copied unnecessarily.

This answer is actually wrong as the first comment notes, despite its high reputation and despite its being accepted. This is unfortunately the dark side of stackoverflow.Cloud Storage allows developers to quickly and easily download files from a Google Cloud Storage bucket provided and managed by Firebase.

To download a file, first create a Cloud Storage reference to the file you want to download. Once you have a reference, you can download files from Cloud Storage by calling the getBytes or getStream. If you prefer to download the file with another library, you can get a download URL with getDownloadUrl. Download the file to a byte[] with the getBytes method. This is the easiest way to download a file, but it must load the entire contents of your file into memory.

If you request a file larger than your app's available memory, your app will crash. To protect against memory issues, getBytes takes a maximum amount of bytes to download. Set the maximum size to something you know your app can handle, or use another download method.

The getFile method downloads a file directly to a local device. Use this if your users want to have access to the file while offline or to share the file in a different app. If you want to actively manage your download, see Manage Downloads for more information. FirebaseUI provides simple, customizable, and production-ready native mobile bindings to eliminate boilerplate code and promote Google best practices.

Using FirebaseUI you can quickly and easily download, cache, and display images from Cloud Storage using our integration with Glide. Then you can load images directly from Storage into an ImageView :. Downloads continue in the background even after activity lifecycle changes such as presenting a dialog or rotating the screen. Any listeners you had attached will also remain attached.

This could cause unexpected results if they get called after the activity is stopped. You can solve this problem by subscribing your listeners with an activity scope to automatically unregister them when the activity stops. Then, use the getActiveDownloadTasks method when the activity restarts to obtain download tasks that are still running or recently completed.

The example below demonstrates this and also shows how to persist the storage reference path used. There are a number of reasons why errors may occur on download, including the file not existing, or the user not having permission to access the desired file. More information on errors can be found in the Handle Errors section of the docs.

You can also get and update metadata for files that are stored in Cloud Storage. Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4. For details, see the Google Developers Site Policies. Overview Guides Reference Samples Libraries.
