This is the code that is used with the app first starts up to check
permission.
`function androidPermissions()
{
let permissions = cordova.plugins.permissions;
let list = [
permissions.WRITE_EXTERNAL_STORAGE,
permissions.READ_EXTERNAL_STORAGE
];
function error() {
console.warn('External Read or Write permission is not turned on');
}
permissions.checkPermission(list, function (status) {
if (!status.hasPermission) {
permissions.requestPermissions(
list,
function(status) {
if (!status.hasPermission) error();
},
error
);
}
}, null);
}
document.addEventListener("deviceready", androidPermissions, null);`
and to read
`function Fail(evt)
{
console.log(evt.target.error.code);
}
function error(e)
{
console.error("error in " + e);
}
function readConfig(entry)
{
entry.file((file) =>
{
var reader = new FileReader();
reader.onloadend = () =>
{
// do whatever you need to do for reading the file.
};
reader.readAsText(file);
}, () =>
{
console.error("error loading config file.")
});
}
let cordova = window.cordova || null;
if (cordova)
{
document.addEventListener("deviceready", () =>
{
window.requestFileSystem(1, 0, null, Fail);
window.resolveLocalFileSystemURL('file:///sdcard/{whatever
file here]', readConfig.bind(this), error);
});
}`
