I'm trying to save some files on my local File storage So, I'm doing Something like below
var folder_name = "abcde/" + viewModel.dir_path;
const documents = fileSystemModule.knownFolders.documents();
documents._path = android.os.Environment.getExternalStorageDirectory().getAbsolutePath();
const folder = documents.getFolder(folder_name);
var file = fileSystemModule.path.join(folder._path, this.pdf_url.split("/").pop());
var url = this.pdf_url;
httpModule.getFile(url, file).then(function(result) {
console.log(result);
Toast.makeText(`${result._name} is succesfully downloaded in ${folder_name}`).show();
}, function(e) {
console.log(e);
});
the only problem is the hardcoded value abcde/ I want it to be app name. whatever the app name is it should take that name.
I don't find any ways to read app name programatically. I need this to Android I'm not interested in IOS.
may be this is one could be the answer. but still this is not a proper way
const documents = fileSystemModule.knownFolders.currentApp();
console.log(documents); --> "/data/data/org.nativescript.app_name/files/app"
var str = documents;
var arr = str.split("/")[3];
console.log(arr.split(".")[2]); ---> app_name
In Android, you can set the app name for the application in strings.xml, for example:
<string name="app_name">"App_Name"</string>
Then whenever you want to reuse the app name, you can use the getString method with its name in the application.

I want to copy storage.db to documents or downloads folder. It's very easy to get the file path:
const filePath = application.android.context.getDatabasePath("storage.db").getAbsolutePath();
But, what isn't that easy is to copy that file to a folder users have access to. I searched this whole forum, and I found nothing useful for my case.
I'm using NativeScript 4.0.1 with vanilla JS.
If you want to share the DB file, the easiest way is to use nativescript-share-file plugin, send the file path and it will give you a nice dialog with intent picker, user may choose to Email the file Or save it to local folder etc.,
const shareFile = new ShareFile();
shareFile.open({
path: filePath,
});
I finally found the solution. I've seen so many users trying to achieve this, and I hope this will help all of you.
Add this to your AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Install nativescript-permissions:
npm i nativescript-permissions
Asking for permission:
const permissions = require('nativescript-permissions');
permissions.requestPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE, "");
Require the necessary modules:
const fileSystemModule = require("tns-core-modules/file-system");
const application = require("application");
Then, create this function where you need to use it:
function copyFile() {
var myInput = new java.io.FileInputStream(appModule.android.context.getDatabasePath("storage.db").getAbsolutePath());
var myOutput = new java.io.FileOutputStream("/storage/emulated/0/databases/storage.db");
try {
var buffer = java.lang.reflect.Array.newInstance(java.lang.Byte.class.getField("TYPE").get(null), 1024);
var length;
while ((length = myInput.read(buffer)) > 0) {
myOutput.write(buffer, 0, length);
}
}
catch (err) {
console.info("Error", err);
}
//Close the streams
myOutput.flush();
myOutput.close();
myInput.close();
}
exports.copyFile = copyFile;
In my case, the file storage.db will be copied to /storage/emulated/0/databases. If you need to create a folder, just do the following:
try {
var javaFile = new java.io.File("/storage/emulated/0/newfolder");
if (!javaFile.exists()) {
javaFile.mkdirs();
javaFile.setReadable(true);
javaFile.setWritable(true);
}
}
catch (err) {
console.info("Error", err);
}
If the destination folder has a file with the same name as the one you want to copy, you need to remove it first. That's why you should create a specific folder to guarantee it's empty.
I have a lot of picture links in my Google Sheet:
https://drive.google.com/file/d/1BDj24_6uz-ZQlGWLy0o1_DES6tJI3NMu/view?usp=sharing
I want to get the filename behind the link. When i open the link and save the image the image filename is: "FILENAME.jpg" or something similar
I want to get this information in Sheets.
How can i do that?
An Apps Script Solution
Thanks to #Tanaike for obtaining clarifications in the comments.
First enter your links in the format shown below in a Google Sheet.
The name of the titles is not important, but this particular script starts getting names from the 2nd row.
If you don't know how to create a script, there are tutorials here offered by Google. You should create the script from the same Sheet. That is, from the menu in the Sheet:
In the script editor, copy and paste the following code:
function getNames() {
var activeRange = SpreadsheetApp.getActiveSheet().getDataRange();
var height = activeRange.getHeight();
var links = SpreadsheetApp.getActiveSheet()
.getRange("A2:A" + height)
.getValues();
var nameValues = [];
links.forEach((row) => {
try {
var link = row[0];
var fileID = getIdFromLink(link);
var name = DriveApp.getFileById(fileID).getName();
nameValues.push([name]);
} catch (e) {
nameValues.push(["NO NAME FOUND"]);
}
});
var nameRange = SpreadsheetApp.getActiveSheet().getRange("B2:B" + height);
nameRange.setValues(nameValues);
}
function getIdFromLink(link) {
var regex = new RegExp(
/(?<=https:\/\/drive\.google\.com\/file\/d\/)(.+)(?=\/)/
);
return regex.exec(link)[0];
}
Run the getNames function. The first time it will ask you to grant some permissions, grant them. Then it should fill in the files names.

I am building an app for an LG Smart TV. I need to load json data from a USB drive when it's inserted into the smart TV.
I'm not sure how to do this, never worked on an app like this.
My question is how do I gain access to external storage and load json data into my app?
Using the SCAP API (v1.2+)
function readFile() {
var successCb = function (cbObject) {
var data_text = cbObject.data;
// do something with the json string
};
var failureCb = function (cbObject) {
var errorCode = cbObject.errorCode;
var errorText = cbObject.errorText;
// do something with the error
};
// Read the whole file from the beginning, as a text file.
var options = {
path: "file://usb:[INDEX]/[FILE_PATH]",
position: 0,
encoding: 'utf8'
};
var storage = new Storage();
storage.readFile(successCb, failureCb, options);
}
The filepath for a usb is file://usb:[INDEX]/[FILE_PATH] [INDEX] is the usb index (could have multiple USBs connected).
Additional help can be found here: http://webossignage.developer.lge.com/api/scap-api/scap16/storage/?wos_flag=readFile#readFile
You can use getStorageInfo() to check if your usb is available.
enter code hereBecause I can't get pass/fail logging to work correctly with the 4.6 version of Instruments, I'm trying to use the tuneup.js library, but I keep getting the following error whenever I try to run the test:
Can't find variable: test
Here's the code:
//We want to use the tuneup library to add extra capabilities
#import <tuneup_js/tuneup.js>
#import <tuneup_js/test.js>
var target = UIATarget.localTarget();
var target = UIATarget.localTarget();
var app = UIATarget.localTarget().frontMostApp();
test("Test1", function(target, app) {
//Do UI automation stuff
var titleDisplayed = tableView.cells()[0].name();
var StoryName = "My Dogs!";
UIALogger.logMessage("My Story Title: " + titleDisplayed);
UIALogger.logMessage("Innocuous Message-1.");
assertEquals(titleDisplayed, StoryName);
}); // <------Error points to this line!
//End test
Any idea what I'm doing wrong? The tuneup.js library is in a folder called tuneup_js which is in the root of the directory which contains my test script (an Instruments trace file), and I don't get any import errors on start.
The problem is that Instruments cant find the *tuneup_js* library so it doesn't find the test function .You need to add the imports in quotes and you dont need to add tuneup_js/test.js because tuneup_js/tuneup.js includes all the classes needed
//We want to use the tuneup library to add extra capabilities
#import "tuneup_js/tuneup.js"
var target = UIATarget.localTarget();
var target = UIATarget.localTarget();
var app = UIATarget.localTarget().frontMostApp();
test("Test1", function(target, app) {
//Do UI automation stuff
var titleDisplayed = tableView.cells()[0].name();
var StoryName = "My Dogs!";
UIALogger.logMessage("My Story Title: " + titleDisplayed);
UIALogger.logMessage("Innocuous Message-1.");
assertEquals(titleDisplayed, StoryName);
});
I found the nsINavBookmarksService, however since Firefox 3, it does not seem to have any API methods for getting/setting the Bookmark description. (API doc)
I've seen other Add-Ons modify the description as a method of synchronized data storage (which is exactly what I'm trying to do). I'm guessing perhaps the description is a non-gecko standard, and that's why it is not directly supported, but then there must be a completely different interface for manipulating Bookmarks that I haven't discovered.
Can anyone help with this newbie problem?
Starting with Firefox 3 the bookmarks have been merged into the Places database containing all of your browsing history. So to get the bookmarks you do a history query, like this (first line is specific to the Add-on SDK which you appear to be using):
var {Cc, Ci} = require("chrome");
var historyService = Cc["#mozilla.org/browser/nav-history-service;1"]
.getService(Ci.nsINavHistoryService);
var options = historyService.getNewQueryOptions();
var query = historyService.getNewQuery();
query.onlyBookmarked = true;
var result = historyService.executeQuery(query, options);
result.root.containerOpen = true;
for (var i = 0; i < result.root.childCount; i++)
{
var node = result.root.getChild(i);
console.log(node.title);
}
That's mostly identical to the code example here. Your problem is of course that nsINavHistoryResultNode has no way of storing data like a description. You can set annotations however, see Using the Places annotation service. So if you already have a node variable for your bookmark:
var annotationName = "my.extension.example.com/bookmarkDescription";
var ioService = Cc["#mozilla.org/network/io-service;1"]
.getService(Ci.nsIIOService);
var uri = ioService.newURI(node.uri, null, null);
var annotationService = Cc["#mozilla.org/browser/annotation-service;1"]
.getService(Ci.nsIAnnotationService);
annotationService.setPageAnnotation(uri, annotationName,
"Some description", 0, Ci.nsIAnnotationService.EXPIRE_NEVER);
For reference: nsIAnnotationService.setPageAnnotation()
