We included examples of both cases: a section with public files visible to everyone and a private section, only accessible through authentication, where files are restricted. Firebase Storage can be used for any type of files, but in this tutorial we will focus on images. Files can be either public or protected using security rules to determine who has access to them. Although this guide is about Firebase Storage, it’s important to mention that there are many other storage options available, such as Amazon s3.Ĭloud Storage for Firebase is built for app developers who need to store and serve user-generated content, such as photos or videos. There were many use cases that came to my mind while writing this tutorial, for example: a learning app with public and private content where private content is only available upon subscription.

We will explain how to handle both public and protected files.

In this tutorial, you will learn how to upload and download images to firebase storage from an Ionic app. Files are part of our everyday life so learning how to handle them in our applications is a crucial task. Images, audios, videos, text documents, pdfs, you name it. Dayana writes often about what you can do with Ionic, Angular, and Firebase. where she helps build great UI templates for developers to get started with.

I am still working this problem and will try and get back here with an update soon (hopefully less than a year next time).This is a guest post from Dayana Jabif, Ionic Insider and co-founder of Ionic Themes and Angular Templates. After all the updates that he SGS and the EVO 4G have gone through, the result is still the same. The test devices that I have are not ROOTed and hence no access (DUH!). UPDATE 4: I think last February was a total blonde moment for me (see UPDATE 3). I need to figure out 2 things here, why it is like this and how to over come this issue in the wild. The issue appears to be that DDMS and my app do not have r/w access to the directory. I am not sure why it is this way, maybe something to with Sprint? I have found this set this way on an HTC Hero, Samsung Epic (Galaxy S), and HTC EVO all on Sprint. I have figured out that the permissions on the /data/ directory on the physical devices are: drwxrwx-x. UPDATE 3: (2/9/11) - I think I may have found what the problem is here, but I am not sure about how to deal with it. Any one have any thoughts on this? The device is properly configured and can run app from eclipse or adb. UPDATE 2: 2/4/11 - I have found that I cannot see the file structure on the physical device (data directory) under any circumstance. File newfile = new File(this.getFilesDir() + "/data/files/", "sample.txt")

The code generating the exception is below, any thoughts on why my app can't access the internal storage? I have this problem on three different physical devices using two API levels (API 7 and 8). Update (2/2/11): Using a EVO (API 8) I still get a NullPointerException. Any help would be GREATLY appreciated, Thanks in advance! I am running the code on a HTC Hero, updated with the latest service release from Sprint. Private File fILE = new File("Mydata", main.FILENAME) What ever method I use, I either find that the file did not create (or change if I place the file manually on the SDCard), or I get a NullPointerException when I try to reference the file or file location: It is a small file containing a name, phone number, and a couple of type int flags. To be clear, I am trying to write to the device's internal, private storage. I am beginning to feel that I am missing some important bit of code, or a setting flag somewhere, I have set the permission in the manifest file: I have tried many solutions listed in other answers, following the code and instructions suggested exactly and find the same result. I have also tried to create the file on the SDCard with the same result, fail. I have also tried to create the file using the methods available in the java.io.File with the appropriate methods.
The simplest solution, it seems, would be the one suggested here:īut I cannot get this to work on my test device. I have read through many questions on here (StackOverflow) and tried the solutions suggested with no success. I am trying to save some data from my app in a simple text file on the internal private storage area (app user preferences).
