I'm relatively new to Android Dev and I'm running Android Studio on SDK 29 for a project to read through messages, find Roster text messages for where I work and then import them into the Google Calander via API. I've had a small amount of experience with Android before so the text and onClick etc are fine (Although I used java in the past, trying kotlin as it's the future). However I'm trying to play around with reading the body of all messages and just printing them to the screen so I can understand how it works, tweak things here and there and see the results I get. However just getting the body of messages and printing them is turning out to be quite difficult.
I had issues initially however they were to do with permissions not working correctly. From there I fixed that issue and got some working code with no errors however instead of getting an output of the body of the messages I got a random '12'. So after further researching and googling I've managed to get myself to what I think is a close lot of code however, it's just incomplete and I'm unable to see what errors there may be as I haven't found a working lot of code online yet.
Furthermore the android dev documentation hasn't been a huge help. So I'm reaching out. Sorry if this seems a easy fix however it's new to me and I havent' found anything online after a fair bit of searching.
Thanks in advance
This is my code so far:
var cr = contentResolver.query(
Uri.parse("content://sms/inbox"),
null,
null,
null,
null
)
if(cr.moveToFirst()){
do {
var msgData = ""
for(messages in cr.getColumnIndex("body")) {
lastSyncMessage.text =
lastSyncMessage.text.toString() + " " + msgData.toString()
}
}while(cr.moveToNext())
}
}```
Try the next code, the for loop is not correct:
if(cr!= null && cr.moveToFirst()){
do {
lastSyncMessage.text =cr.getString(cr.getColumnIndex("body"))
}while(cr.moveToNext())
}
This code will set the last sms body message as the lastSyncMessage text. Just play with this.

I'm working on Ionic mobile app development.
My requirement is to create client side logger to track issues in app. I used the methods mentioned in https://github.com/pbakondy/filelogger, and I could able to create the log file in both Android and iOS.
For the first time when I open the app, it creates the log file in cordova.file.dataDirectory, when I close and reopen the app in i*OS, I'm trying to read the content of the file which was created using the below
$fileLogger.getLogfile().then(function (loggerContent) {
var temp =loggerContent;
});
But the application says
{
"applicationDirectory":null,
"applicationStorageDirectory":null,
"dataDirectory":null,
"cacheDirectory":null,
"externalApplicationStorageDirectory":null,
"externalDataDirectory":null,
"externalCacheDirectory":null,
"externalRootDirectory":null,
"tempDirectory":null,
"syncedDataDirectory":null,
"documentsDirectory":null,
"sharedDirectory":null
}
So I couldn't able to find the file where i saved my logs.
Please help me resolve this issue or if you could recommend me a different method to get around this issue, that would be great!
Thanks for the answers
There is a check list here and should solve your problem :
1-Be sure that the cordova-file-plugin is installed and works in your test environment.
2-Be sure that the cordova.js file is refrenced by your html and before your code usage.
3-Be sure to call your codes after device_ready state :
check this
4-Call your function after a short delay (use setTimeOut in Javascirpt)
Ali's item 4 is very important:
I had a similiar problem on different platforms: cordova.file.dataDirectory was null.
I tracked cordova.file.dataDirectory over the lifecycle and it was first accessed by my Ionic 2 code BEFORE the device ready event was fired.
My "mistake": I wanted to load data during the constructor(!) of a service. Seems too early.
My code used to work, it does not work anymore, I tried troubleshooting and can't figure out why.
I have this piece of code in my PHP:
$android_id_01 = $_GET['pmysql_room_id'];
$android_id_02 = "";
$f = fopen("00_android_id_01.txt", "w");
fwrite($f, print_r($android_id_01, true));
fclose($f);
$f = fopen("00_android_id_02.txt", "w");
fwrite($f, print_r($android_id_02, true));
fclose($f);
For troubleshooting I created two android IDs ($android_id_01 and $android_id_02) which are both empty (The first one is From Android and the second one I created directly from PHP).
Now when I launch my Android device, the PHP file is executed from server side and both the text files are created empty and identical. Now my code only works when I use $android_id_02 and not $android_id_01 from the code below:
if ($android_id == '')
{
//my code
}
(Yes when I use either one of the $android_id_01 OR $android_id_02 I rename it to $android_id and comment out the other one)
My question is, although this was working yesterday, why does it work with $android_id_02 = ""; and not $android_id_01 = $_GET['pmysql_room_id']; even though they are both empty????
I don't know what changed from yesterday to today.
Ok after a bit of troubleshooting I found a solution, strange though.
On the server side "display_errors" under PHP settings must be turned off. Somehow having this on interferes with the json_encode sent back to android client. (even though my code is not generating any errors)
For some reason, when I restart my PhoneGap app - it looses the localStorage vales that were stored before! I'm saving them in the normal way:
localStorage.setItem("foo","value");
This stores it just fine. However, when you restart the app (or leave the device off for a random amount of time), it seems to randomly loose the data. I've found a heck of a lot of posts about this - but no definative answer on how to get it to be persistent in a PhoneGap Build WebView app,
Any suggestions are much welcomed!
This seems to be quite a common problem with WebView apps:
Android 2.3.6 + Phonegap + localStorage
Android - Making Webview DomStorage persistant after app closed
I can't find a solution that works with PhoneGap Build apps though
An actual example I'm using, is:
var current_id = parseInt(currentId) + 1;
localStorage.setItem("entry_"+current_id,save_string);
localStorage.setItem("entryId",current_id);
..and then to extract it (not that this is important, as the problem is with the data going missing, and not with accessing it)
for (var i = 0; i < localStorage.length; i++){
if (localStorage.key(i).match("entry_")) {
outputString += "\n" + localStorage.getItem(localStorage.key(i));
}
}
I'm wondering if maybe upgrading from PhoneGap Build cli-5.2.0 to cli-6.0.0 may help. I will do this, and give it a whirl.
I guess another option, would be to use a SQL database to locally store the device (its just a bit trickier to setup, and means re-writing my code)
UPDATE: Not the ideal solution - but I have now moved the app over to use WebSQL for the app. It was a bit tricky to get the hang of (never used it before) - but seems to do the job, and shouldn't loose the data :)
EDIT
i tried it like this and it worked:
var current_id = parseInt(currentId) + 1;
localStorage.setItem("entry_"+current_id,save_string);
localStorage.setItem("entryId",current_id);
/*
//this is for checking, what is stored in localStorage
console.log("length: " + localStorage.length);
for(var i = 0; i < localStorage.length; i++) {
console.log(localStorage.key(i));
}
*/
var myEntryIdFromStorage = localStorage.getItem("entryId");
var myItem = localStorage.getItem("entry_" + myEntryIdFromStorage);
Old answer for clarification
How do you get your localstorage?
normally you should store items like you did:
var permanentStorage = window.localstorage;
permanentStorage.setItem("foo", "bar");
and get them back by initializing the permanentStorage the same way and:
//assuming you have permanentStorage in the same script file
//or else you have to initialize it again:
//var permanentStorage = window.localstorage;
var myItem = permanentStorage.getItem("foo");
console.log("myItem: " + myItem);
The method store item uses two parameters: the identifier and the data itself. Please check, that the identifier with which you store your data is the same as the one, with which you get it back.
Do you get any errors? Is the return (stored in my example in myItem) null or undefined or just an empty string? Does this fail in the browser or on the device?
You could clarify your question by providing more code or error messages!
I want to access a android device from python to download some photos.
libmtp works from the CLI.
Than pymtp. It's been around for a while but it's designed for python 2 and i'm using python 3. Meanwhile fixed several minor issues but i'm stuck at an error from function get_filelisting
specially this section:
ret = []
next = files
while next:
ret.append(next.contents)
if (next(next.contents) is None):
break
next = next(next.contents)
The error is related to the "next".
That section looks strange to me, i've been coding in python for a while but i'm new to ctypes. Tried a lot of variants, they all failed. The "next" could be confusing with python buildin function so i renamed it to nextpointer and came to this code:
ret = []
nextpointer = files
while nextpointer:
ret.append(nextpointer.contents)
nextpointer = nextpointer.contents.next
It seems to work but did it work by accident ? does it have any design flaws ? Could anyone with experience on python ctypes confirm this a solution ? Any suggestion welcome.
From python2.7 documentation
next(iterator[, default])
Retrieve the next item from the iterator by calling its next() method. If default is given, it is returned if the iterator is
exhausted, otherwise StopIteration is raised.
from python3 documentation
next(iterator[, default])
Retrieve the next item from the iterator by calling its __next__() method. If default is given, it is returned if the iterator is
exhausted, otherwise StopIteration is raised.
Notice that next() method was removed from python3 but the function still exists.
This is all I can say about the next function and .next()/__next__() methods.
I downloaded the pymtp module and get_filelisting() is slightly different from what you posted in your ported code, here it is:
ret = []
next = files
while next:
ret.append(next.contents)
if (next.contents.next == None):
break
next = next.contents.next
If none of this helped you (which probably didn't :D), the version of pymtp library that I am using is 0.0.6 download using pip.
I'm building an Application that integrates with your Nest devices (both the thermostat and the Nest Protect, but this issue is about the thermostat).
What I'm trying to do is set my thermostat's ETA to be in x minutes (2 hours for example so 120 minutes).
This is my code that I'm executing:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSZ");
final String path = buildStructureFieldPath(structureID, Keys.STRUCTURE.ETA);
Structure.ETA eta = new Structure.ETA.Builder()
.setTripID(tripId)
.setEstimatedArrivalWindowBegin(sdf.format(estimatedArrivalBegin))
.setEstimatedArrivalWindowEnd(sdf.format(estimatedArrivalEnd))
.build();
sendRequest(path, eta.toJSON().toString(), listener);
The path is /structures/MY_STRUCTURE_ID/eta
Unfortunately that's not working. I'm always getting an error code -2 and error message: No write permission(s) for field(s): eta
And that's were it gets strange. No permission, but I did request the permission and I did an authenticate, which is successful, before launching the update call.
In the two attached screenshots you can see first my Nest Developer Account where you can find the ETA write permission and in the second you can see the logging from within my app (using the NestAPI as can be found on GitHub, just added the ETA feature myself).
Anyone have any idea on how to solve this issue?
Can you print out the exact JSON blob you're sending and post it here? (the value of eta.toJSON().toString())
Best guess is that it isn't formatted exactly correctly and as such is maybe attempting to write in such a way that doesn't adhere to the api-reference.
This is the format that it needs to match:
"eta": {
"trip_id": "myTripHome1024" ,
"estimated_arrival_window_begin": "2015-10-31T22:42:59.000Z" ,
"estimated_arrival_window_end": "2015-10-31T23:59:59.000Z"
}
Single line:
{"eta":{"trip_id":"myTripHome1024","estimated_arrival_window_begin":"2015-10-31T22:42:59.000Z","estimated_arrival_window_end": "2015-10-31T23:59:59.000Z"}}
To pinpoint exactly which field may be erroneous, try sending just one change at a time for each ie: structures/ID/eta/trip_id, etc for the others.
Useful JSON Validator: http://jsonlint.com/
You could also try to send it to /structures/MY_STRUCTURE_ID.json?auth=[TOKEN] instead of /structures/MY_STRUCTURE_ID/eta.
