android - Guaranteed space to write files to? -


in app want save quite lot of settings , configurations. read text file in assets folder. being updated fromn server time time.

i thought 2 options: save them in sqlite database via ormlite or save them json string in text file. found out reading them json faster reading them database, i'd prefer option. remember apps did quite time ago ran issues when writing files device, sdcards not being available, permission stuff etc.

is there space / path on android file system guaranteed able use code , guaranteed available @ time?

as seen in docs:

internal storage:

  • it's available.
  • files saved here accessible app default.
  • when user uninstalls app, system removes app's files internal storage.

unless unexpected happen, can safely use internal storage.

but @zmarties said, use sharedpreferences - it's easier use , should enough contain big data.

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
