Cant Download Because No Internal Storage Is Available
Zayne Plascencia
I want to save a json file with all the application data (something similar to preference) but im not sure what is the limit size, because if the app cant use this file it will not function probably. is this information known beforehand and the OS reserve some space for your app or its based on the size available.
Update: I dont really care about External storage since is not always available in the device and could be changed (SD card) and i could check for internal storage using this but this is not what i want to know, What i want to know if there's a memory size allocated for internal storage for the device ?
If you use Environment.getExternalStorageDirectory() (or Context.getExternalFilesDir() for API level 8 and up) as the place for your json file, then I believe the size will be limited by the available space in the external storage (usually an SD card). For most devices, I believe there are no fixed limits built into Android for external file storage. (Internal storage is a different matter. Device manufacturers can impose quite restrictive limits, perhaps as low as 100MB shared among all applications.)
Beyond the requirements above, device implementations SHOULD have at least 1GB of non-volatile storage available for user data. Note that thishigher requirement is planned to become a hard minimum in a future version of Android. Device implementations are strongly encouraged to meetthese requirements now, or else they may not be eligible for compatibility for a future version of Android.
This space is shared by all applications, so it can fill up. There is no guaranteed minimum storage available for each app. (Such a guaranteed minimum would be worthless for apps that need to store more than the minimum and would be a waste for apps that store less.)
For internal storage I think your only limited by the amount of internal storage made available for all applications to share. Which as @Ted Hopp mentioned is rather small on some of the older and lower end devices. But on the newer and higher end devices they've started bumping it up to a reasonable amount, though even if the device has a lot of space, it could still be taken up by other applications(so you need to test what will happen in this scenario).
It is also worth pointing out that if you use external storage such as the SD card then your json file would technically editable by the user. They could open it up in a text editor and start changing the raw values if they had any desire to. (This is also possible if you choose to use internal storage, but it would require a rooted device, whereas if it is stored on the SD card would not require root)
My device storage is way beyond 1GB and I have used it with space as low as 200MB without this issue. But my termux installation has grown to 3.61GB. I recently started with yarn and it seems like yarn is a space hog. I was installing a package and it suddenly logged: error Could not write file "/data/data/com.termux/files/home/dev/ide/theia/yarn-error.log": "ENOSPC: no space left on deviceSo it crushed the installation and thought i really ran out of space, but I hadn't. Further inspection shows that i still have the aforementioned space in internal storage and yarn has hogged 750MB, of which npm only about 500MB in cache. I have been using npm since, but just needed to use yarn as the installation for Theia wasn't finishing well with npm. Theia seems to be using yarn as their package manager. So 3.61GB hints to be the hard limit for app + data.
To assert this, someone else should try to use an app that creates really large files in its internal sandbox. Not in the internal storage, but in its private data area. I am sure you will likely hit this hard-limit.
If you're seeing an "Insufficient storage available" message on your Android, chances are that you've used up most of your device's available memory. To fix this, you'll need to make some space by deleting apps and/or media; you can also add external storage, such as a Micro SD card, to your phone. In some cases, however, this error shows up even when you have plenty of space. This wikiHow article teaches you how to fix the insufficient storage available error on your Android.
If that iCloud backup worked just fine, then great, you're done. But I realize a lot of people won't be able to back up to iCloud without a little work. You might see this message on your iOS device: "This iPhone cannot be backed up because there is not enough iCloud storage available."
The popularity of the mobile device market (smartphones and tablets) has opened up an allied opportunity for companies - augmenting the limited storage available in those devices with portable wireless devices while adding extra functionality to make them compelling offerings. Under the 'wireless storage' category, we have already looked at various offerings such as the Kingston Wi-Drive, Seagate GoFlex Satellite, Patriot Gauntlet Node, Buffalo MiniStation Air Wireless Hard Drive and the Seagate Wireless Plus. All these units have a hard drive or flash drive, a Wi-Fi radio and a battery. In conjunction with various mobile apps, they enable a host of interesting use-cases. Given the popularity of this market category, it is surprising that Western Digital has not had any play in it. Things are changing today with the launch of the My Passport Wireless Wi-Fi Mobile Storage lineup.
