[Q] How to access main application SharedPreferences for Home Screen Widget? - Android Q&A, Help & Troubleshooting

I have an app that stores the location of the last opened database in it's SharedPreferences, I have no issues working with this inside the main application BUT...
I am trying to create a Home Screen Widget for this app and I need to access that preference some how so that I can open the database from inside the Widget. I have done a lot of google searches and I am coming up with nothing very good. It seems "possible" to do this with createPackageContext() but everything I have read indicates that this is not very secure.
I have the ContentProvider working just fine if I hard code the database location, but since the user can open up multiple files I need a way for them to specify in the app the default file they want opened. I guess maybe the "best" method would be to have them select the file when they enable the widget maybe?
I know that I have seen apps that "seem" to be using the SharedPreferences to store the data and it is shared between the Home Screen Widget and the main app, so how can this be done IF it really can be done?
Anyone have any suggestions or locations that I can do more research on?
Thanks,
-Eric

[APP] FBReader "Sync" App - FBSync v1.0.26 (Beta)

Hello all!
Recently I've started using two seperate Android devices to read books
using FBReaderJ for Android, a NookColor, and my phone, a Sprint EVO
3D. Very quickly, I ran into a problem. I read the same books on both
devices, so I ended up spending a lot of time looking for my place
whenever I switched devices (I used the NC at home, and my phone
everywhere else).
I imagine that this must be a problem quite a few people are having,
or will be having as android devices become more popular.
So, I wrote an android app to synchronize my place in each book
between the two devices.
App Name: FBSync
Current Version: v1.0.26
Revision History:
1.0.26 - Removed Auto-Sync feature (hopefully just temporarily. I want to get this working, but the FBReader API just doesn't provide enough functionality to get it working smoothly). Removed syncing of "recent" books (It caused more trouble than it was worth, sorry, you will have to manually open your book if you changed books on another device). Added a "Sync" item to the FBReader menu that pulls up FBSync.
1.0.24 - Updated Dropbox support to use latest Dropbox API. Fixed Auto-Sync feature to properly sync new book positions (broken due to a change in FBReader). Due to limitations in FBReader, the Auto-Sync feature is still rather rough.
1.0.23 - Added a Dropbox support for your book position data, an Auto-Sync feature that makes use of the FBReader API, and (in theory) the program has been translated into Russian (thanks Dmitry!). If you have set up your own synchronization server, you will need to update the PHP files to the files in the attached sync.zip
1.0.19 - Fixed another bug that affected Honeycomb devices. Confirmed working on an Acer Iconia A500.
1.0.18 - Fixed a bug that affected Honeycomb devices (I hope!)
1.0.17 - Added "Alternate Sync URL" functionality for those people who want to set up their own sync server instead of using mine. See below for more instructions.
Requirements:
1) Root. Your devices must be rooted. This application only uses
root for two things. First, it uses root to get access to the
FBReaderJ books database, and second, it uses root to kill the
FBReaderJ process before it syncs the data (it has to kill the process
to force FBReader to reload the database).
2) FBReaderJ must be installed on the device (you will be prompted to
install it if you haven't already when you load my app)
3) You must have already opened FBReaderJ at least once, and viewed
it's library (Menu button, "Library"). This creates the databases
that my application needs.
Download:
An older version is available on Google Play, but the latest version can always be found at the bottom of this post.
Instructions for Use:
As of v1.0.23, you have the option of either syncing book positions to my web server, or to Dropbox. If you choose to use Dropbox, it will create a single file on your Dropbox account (under \FBSync) that contains the book position data.
If you desire to sync the book positions to my web server, you can also enable a new, experimental "Auto-Sync" feature that syncs your position whenever you open or close FBReader (or a book in FBReader). This functionality only works when using my web server, it does not currently work with Dropbox.
The auto-sync feature make use of FBReader's API and makes FBSync work as a plug-in for FBReader. Unfortunately the API does not contain all of the features needed to completely remove the root requirement for FBSync.
If you are going to use my web server to sync:
After you install it, go into the settings (blue icon, or menu/
settings), and enter an email (doesn't have to be an email, any unique
string will work) and numeric pin # (this isn't secure, so don't use a
pin you care about). The email/pin is just to uniquely identify you.
You should use the same email/pin on each device.​
On the same screen, you can choose to sync the actual book files to Dropbox. Since your Dropbox account is used, only your account can access the books, if
you choose to sync them. It only uploads/downloads the books when it
needs them, so it may take a while the first time you sync, but after
that it shouldn't take more than a minute MAX (my typical sync times
for 90 books is about 5-10 seconds)
Click the middle, orange icon, to begin the sync process.
If this is the first time you've synced since selecting the "Enable Dropbox" setting, you will be prompted to allow FBSync access to your dropbox account.
The sync process first uploads, then downloads. It only updates the book's "place" on the web (or Dropbox) if it's farther ahead than the web's "place" for the book.
If you are using the Auto-Sync function, the above statement is not true. It always saves the exact position of your book upon closure of FbReader or closing the book.
Miscellaneous Info:
This program is still in beta. I have used and tested it extensively,
but I'm not liable if you manage to break it somehow. Since it does
alter the data in FBReader's databases (it does not, and never will,
alter the database structures), it is possible, but very unlikely,
that it could lose your book's places. I would suggest that you back
up FBReaderJ using something like Titanium Backup before you start
using FBSync, just to be on the safe side.
The synchronized book position data is currently hosted on my personal web server, or your Dropbox account (as of v1.0.23). Your book files are only stored on your Dropbox account.
UPDATE: As of v1.0.17, I added the ability to define your own "Sync Server". Here's how to use it:
In the Settings (Menu, Settings), there is a new option "Alternate Sync URL" where you can enter your own URL. Leave it blank if you want to use my server.
If you want to use your own, you will need the file attached to this post. I wouldn't recommend trying to set up your own server unless you are pretty comfortable with web servers, php, and mySql.
Sync.zip contains a .SQL script, and several .PHP files that are required to set up your own sync server.
The primary thing that you need to set up your own Sync server is a HTTP Web server that supports mySql and PHP.
On your server, create a new mySql database (name doesn't matter, just make sure there's a user attached to it that has insert/update/delete rights), then run the sql code in the sync.sql to create the two tables that are needed.
Edit the common.php file and replace the '' values in this block:
Code:
$dbhost = 'localhost';
$dbuser = ''; // Fill out the database user name here
$dbpass = ''; // Fill out the database user password here
$dbname = ''; // Fill out the database name here
with the correct values for your server. $dbhost can probably remain 'localhost'.
Then create a directory on your web server that is accessible from your devices, and put the 5 PHP files into it.
Launch FBSync, hit Menu, Settings, click the "Alternate Sync URL", and type in the URL that points to the directory you put those PHP files in (ex; http://sync.splitmatrix.net/alternate_sync ). You must start it with http://, and it should not end in a /.
After you enter the URL, save out of it, back out to the main FBSync window, and click the Sync button. If you set up everything correctly, it should sync to your server now instead of mine.
Please let me know of any issues you find, or any improvements you
want.
Thanks,
Scott
6/27/2012 Edit - Updated Sync.zip to remove some buggy code from addbook.php
Hi Scott,
I only have 1 device right now, so no need for sync, but I would be interested in how you can read your BN books with FBRreader. I have installed FBReader, but don't know how to read the books with it.
Also, I installed the dolphin web browser and clicked on a few epub links but nothing happens, is there a way to get it to bring up those files in FBRreader?

I haven't actually purchased any books from B&N, but assuming the books you purchased are DRM free, you should be able to just move them into the \sdcard\books directory, and they should appear in the FbReader library. I believe, by default, the B&N books go into the internal storage, in the B&N Downloads\Books directory. Use a file manager like estrong's, astro's, or root explorer to copy them.
Via your web browser, save the epub books to \sdcard\books (or move them there after they download), and they'll show up. I don't believe that you can associate any book reader with epub files, I don't think android supports that. You have to open the book with the app, not the app with the book.
Scott
I use FBReader on multiple devices and would be extremely interested in such an app!
Thanks for your interest in my syncing app.
One pretty major requirement for this app is that your devices have to be rooted. Android doesn't like one app accessing another app's data, so the only way I could do it was to use root privileges.
It's still in beta, but you can download a copy of it at:
http://sync.splitmatrix.net/apk/fbsync.apk
Currently v1.0.9.
After you install it, go into the settings (blue icon, or menu/settings), and enter an email (doesn't have to be an email, any unique string will work) and numeric pin # (this isn't secure, so don't use a pin you care about). The email/pin is just to uniquely identify you. You should use the same email/pin on each device.
On the same screen, you can choose to sync the actual book files as well as their positions. It only uploads/downloads the books when it needs them, so it may take a while the first time you sync, but after that it shouldn't take more than a minute MAX, my typical sync times for 90 books is about 5-10 seconds.
Obviously you should have Fbreader already installed, and you need to have ran it, and gone into the library (menu/library) at least once (this creates the fbreader app database).
Click the middle, orange icon, to begin the sync process. It first uploads, then downloads. It only updates the book's "place" on the web if it's farther ahead than the web's "place" for the book.
Please let me know of any issues you find, or any improvements you want.
Thanks,
Scott
Cool
I just tested and it does work as stated. One question though, where is it uploading the data too?
Personal website, sync.splitmatrix.net. if the app takes off, i'll figure out something more secure and permanent.
Scott
Interesting. I'll try it out. Thank you!
One thing to think about however, especially if you open this up to general usage, is that by uploading/downloading the book file itself rather than just the current read-to position, you could potentially run into copyright issues. There is reason to believe that this could fall under Fair Use, but past rulings on similar commercial services for other media have been inconclusive. That may be a can of worms you don't want to open.
I am not a lawyer, but I do play one on web forums.
One thing I would try would be saving it on Google's servers through IMAP or something like SMS Backup does. Then no need to have to pay for a server. Don't know if it is at all possible but just thought I would see how you liked it.

Yes, this is something I'm aware of. Not sure what I'm going to do about it yet. That's why it's a setting

The server it's currently on is hosted by a friend of mine for free, so I'm not concerned about it at the moment. If thousands of people end up using this, then obviously I'll have to make some changes.
Scott
I wonder if there's a way to store and retrieve the sync data with each user's Dropbox or something...

I'd imagine that there is a way to do this, since programs like Titanium Backup support a dropbox interface.
If enough people think this would be a good feature to add, I can definitely look into it.
Scott
I'm just thinking that using each person's Dropbox would get you off the hook for not only server space and bandwidth, but also any potential copyright liability for book copies made by users synchronizing their files.
Valid points. I'll do some digging and see what it will take to implement the dropbox API in this app..
Thanks,
Scott
Edit: Updated first post with useful information - added download link.
Updated to v1.0.10 to fix a problem when used with the latest FBReader beta. Same URL as before:
Edit: Download the app off the market
Thanks,
Scott
This is a great app this is the missing link in fbreader. I hope you continue to support and enhance it.
Now that my archos tablet is rooted i can really enjoy it. I used to read my books on my phone and occasionally I still do.
Thx for the great work.
This looks like a dang good app. Since getting my nc i've quit using my evo for reading. This sync will bring joy back to my bathroom bbreaks at work!
Thanks for your kind words!
Since the last time I posted to this thread, I've added a dropbox interface to the program, and posted it to the Market (for Free of course!), so if you've downloaded the APK from the web, please re-install it from the market for the latest and greatest version.
Thanks again,
Scott
Oh, great! I'm checking out the Dropbox syncing now.
Edit: Works great!
If I may make another suggestion, you should post about your app at the MobileRead forum. I think you'll pick up a lot of users there.
Also, I know that the Android version of FBReader is different from the PC versions, but syncing with the Linux and Windows versions would be the icing on the cake. MobileRead might be a good place to find others wanting to help develop that capability

[Q] Location field in calendar app

I previously had a Milestone and in the calendar app there any address I entered into the location field would be clickable and offer an option to open maps or navigate to it. In the samsung app I can add a location but it is not clickable. I have seen that you can open the map from the edit screen but this seems only to let you get a single map image rather than giving full functionality. Is there a setting somewhere I am missing?
Edit: I tried installing Jorte calendar and that has clickable address links working. When viewing the same event in both only Jorte allows me to click through.
Looking into this it seems the feature is simply missing from the samsung app rather than not activated and has been since the original galaxy. Is this something that can easily be modded?
I am needing this feature as well. When I had my captivate, stock did not have this but with the cognition rom it seemed to work. I don't know how it was modded to work. However, when I updated my captivate to the 2.2 stock firmware I897UCKB1, it had this feature. Now that I have a SGS2 its very disappointing that it doesn't have this again. I use the Clickable address location in calendar every day to get to appointments. It is so frustrating to have to open the appointment, edit the appointment, copy the address from location, hit home, open maps, hit search, paste the address, and hit search again while driving. This could all be done with one click if the location was clickable. I am willing to donate $15 to anyone able to give a solution using the SGS2 stock calendar app. Thanks.

The best i could think of is to do a search of the location before hand copy then copy the link to the description part on the calender entry. Also add the location snapshot (this is just a picture as you might have aready noticed). Now when the appointment pops up, just click the link(set it up to open with maps). This way you can getting the navigation running from the appointment itself.
add another one to the list of people who really need this feature.
i have just come from a year with a htc desire and its something i really miss.
This is a silly oversight. Something that other apps on the market implement without issue. I'm disappointed!

[Q] Set Google search to search only on phone by default

Hi, i often use google search to search the name of apps instead of using the drawer. I've enabled the search on local phone, including app, chrome and contacts. When i type an app name, i got at first (on top) the name of the app, and when i'm going to tap on the icon, three suggestion from web appears on top, and the app goes down. The beavior is very variable, because of the presence of internet connections (in such case no suggestions) and its delay (mobile data vs. Wifi).
It's really annoying beacuse i use the search to open the app quickly, and often i click on the randomly popping-up suggestion, which open Chrome, etc.. (at the end is anything but quick).
There's a way to disable these suggestion, or use directly the phone (local) search?
Thank you.

[Q] Secure Contacts Manager/Address Book (with db encryption) [Android]

I am looking for a secure contact (and related misc. information) manager/phone-address book that encrypts the database and protects its records from other apps as well as in case of the phone being lost. This is for Android.
I've been looking for such an app for quite some time and in various sources. I found some people asking for something similar, but with no answers. I also found some "secure wallet" programs that could almost do the trick, except that they store secure information but no people's contacts. While, of course, I can record phone numbers (and addresses) in a free-note format, that wouldn't allow easy dialing of those numbers, or easy copying of the addresses to the navigation apps (Google Maps, Waze, etc.).
None of the contacts managers I found offer encryption/protection.
I couldn't find any discussion about this type of app. I am surprised why nobody is interested in such an app. Or am I just looking in a wrong way?
Do such apps exist?
I have been looking for the same thing.
So far the only thing I have found is essential pim pro app. It uses it's own encrypted database to save the contacts. It also can share the contacts through an account in Android 6+ (not sure how secure that feature is)
There was a very old personal information manager app that had very few permissions that might also work but I have not used it in 4 years and forget the name(not could I find it when I searched Google play)
So I'm still looking for a open source app that is very similar.

Stock Calendar Map issue

In EMUI 9, stock Calendar app added "Map" button when creating a new appointment, to find the location.
However in order to work properly you need to press that button and find the location by scrolling and moving the map to the correct place. There is no search option to search for the location you want.
In addition, if you simply type the location you want and save the appointment, the "Show on Map" button in the event opens another app (amap) which does not work in Europe, so you cannot navigate there.
Does anyone have the same issue? Any solution to this, apart from using another app?
I have tested right now:
- I can create a new task without entering the location
- if I write the place name manually, I can't open it in the map, nothing is happening after pressing the location button
- if I select the place on the map, I can open it later in Firefox and Google Maps
IMO, stock Calendar app works good.
A pain in the ass work around is manually typing address in, then when you want to view it on map, click and long hold the address and it will open Google maps and search the address.
It sucks that it won't do it by default, but the weather information on the calendar/schedule needs the location set properly to pull weather data
But the Europe address seems to work for me

Thank you very much for your reply. Indeed your suggestion works, with one small tradeoff, the address should be put in English. If I put the address in Greek (my native language) it will not work. But for sure is better than nothing. Thank you very much

Correct, this is how it works, I would prefer though to have a search option on the map, instead of selecting it. But we will have to wait for Huawei to improve stock Calendar app for it. Thank you
