Reads the contents of dirpath in the Android app's assets folder. Note the lowercase d. Stats an item at filepath. If the filepath is linked to a virtual file, for example Android Content URI, the originalPath can be used to find the pointed file path.
The promise resolves with an object with the following properties:. Reads the file at path and return contents. Use base64 for reading binary files. Reads length bytes from the given position of the file at path and returns contents. Note: reading big files piece by piece using this method may be useful in terms of performance. Reads the file at path in the Android app's assets folder and return contents.
Reads the file named filename in the Android app's res folder and return contents. Only the file name not folder needs to be specified. Write the contents to filepath. Append the contents to filepath. Write the contents to filepath at the given random access position. When position is undefined or -1 the contents is appended to the end of the file. Moves the file located at filepath to destPath. This is more performant than reading and then re-writing the file data because the move is done natively and the data doesn't have to be copied or cross the bridge.
Note: On Android copyFile will overwrite destPath if it already exists. On iOS an error will be thrown if the file already exists. Copies the file at filepath in the Android app's assets folder and copies it to the given destPath path.
Copies the file named filename in the Android app's res folder and copies it to the given destPath path. Reads an image file from Camera Roll and writes to destPath. This method assumes the image file to be JPEG file. This method will download the original from iCloud if necessary. URI of a file in Camera Roll. Can be either of the following formats :. Destination to which the copied file will be saved, e.
Copied file's image width will be resized to width. If 0 is provided, width won't be resized. Copied file's image height will be resized to height. If 0 is provided, height won't be resized. Copied file's image will be scaled proportional to scale factor from width x height. If both width and height are 0, the image won't scale. Range is [0. Quality of copied file's image. The value 0. If resizeMode is 'contain', copied file's image will be scaled so that its larger dimension fits width x height.
If resizeMode is other value than 'contain', the image will be scaled so that it completely fills width x height. Default is 'contain'. One can use this method also to create a thumbNail from a video in a specific size.
Currently it is impossible to specify a concrete position, the OS will decide wich Thumbnail you'll get then. A gamepack will consist of:. Right now I'm not really concerned if these are transferred individually or in a zip file though a zip file would certainly be preferred. Of course the device will need to be connected to the Internet to get the current list of gamepacks and to download the ones that the user chooses. Once the gamepacks are downloaded to the phone the user will not need an Internet connection to play the game as they will have all the files.
How do I download the files? Would I use the react-native-fetch-blob library and save it in a specific location? This library refers to saving it as "cache" rather than permanently, so I am not sure if this is the correct solution.
But because it is cache, should I be looking for something else that is more of a longer term storage? It does say on the page that files will not be deleted so I am a bit confused as to what the difference between permanent storage and cache is in this case.
Once the files are downloaded would I then be able to open images and display them, open sound files and play them, and open the json files and process them?
It's important to know that the height and width must be set on the Image. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?
