Android :: ZXing Doesn't Read 1D Barcode In Droid App / Fix For This?

Oct 2, 2010

I am developing a new application which hopefully will use a barcode reader to scan and find books. I will then use the ISBN information to get more information.

The intents work and I can scan 2d barcodes OK but not the 1d barcodes of books which I know scan fine using the full application.

This is my code. I have tried it without putting the intent extras and it doesn't change anything. code...

Is there something obvious I am missing? The settings in the app also are selected on 1d scanning only.

Android : How To Play An Encrypted File In Droid?

Apr 14, 2010

I need to be able to play an encrypted file in Android. The file is AAC. The only way I can see to do this is either: decrypt the file to internal private storage and point the player at that file to play, or decrypt & decode the file to pcm and feed it to an AudioTrack. 1 isn't great because it takes a long time to do that. 2 isn't great either because I don't know how I can take advantage of the HW decoder to do this.

Motorola :: Droid X Encrypted Bootloader And Efuse Thread

Jul 1, 2010

I've updated this OP to make it easier for new comers to find some of the most important posts as well as a few important outside links that inform this thread. It is my personal feeling that if you are reading these forums, and considering buying ANY Android phone, this thread is a very important one to read. It is far better to be informed than to realize after you buy a product that it wasn't what you expected (I almost made this mistake). The main purpose of this thread is to discuss what a signed (encrypted) boot loader is, what the implications of having a signed boot loader are, whether or not the Droid X may have one, why you may care, what you may be able to do about it if you do care, etc, etc. This thread is filled with a lot of long posts (including this one), so prepare yourself for that. Not all of them have tons of merit (mine included) so keep that in mind. Below are some of the most informative posts you'll find in this thread. That said, I highly suggest further reading: there are many great ones that I haven't linked to here.

HTC Droid Eris :: Unable To Get Encrypted WiFi Router Broadcast

Apr 26, 2010

Friends are setting up a wireless router @ work. we all pitch in some cash to pay for the monthly fee. They want to keep it secure. If the router is broadcasting publicly, my eris sees it and will connect. As soon as it gets encrypted, or password protected, I drop signal and my phone doesn't "see" it. I've entered my mac address into the router in hopes that it will broadcast to me. Can't see it.

It won't even show as a "locked" or "secure" WiFi connection. I've set up the wireless preferences according to network ssid and correct password. No success. Is there something screwy with the eris WiFi system? Anyone else run into this problem? Why is it that I can use WiFi if it's an open, broadcasting signal, but can't use or see it when it's a password protected and privately broadcasting signal? Doesn't make sense to me. Is there an app for this?

thanks for the help!

Android :: Zxing Androide Source For Blackberry

Nov 18, 2010

To my knowledge, in the Zxing android source code, there is a custom layout to search for key points in the QR code image (Viewfinder_view). It then analyzes the byte stream of the image.

Can I detach from this design and use the android zxing source code to develop an approach which can be used in both the Android and BlackBerry platforms?

It will be a JAR file which can be used to decode QR codes, using the Android Zxing source.

General :: ZXing Library - Intents Not Working

Jul 16, 2012

I am developing an app that needs to call "Barcode Scanner" using an Intent. Part of the ZXing library is the IntentIntegrator [URL] ......

The IntentIntegrator allows me to use addExtra to the intent. My plan was to read whatever "extra" I added to the intent in the onActivityResult call after the barcode has been read. The problem is that the Barcode scanner application doesn`t return the extras to me after it reads the barcode.

This is my call to invoke the intent:

(...)if (v.equals(btBarcode)) {
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.addExtra(Utils.EXTRA_MODO, "add");

[Code] ....

Is this the way it is supposed to work (and thus I'll have to find a way to know what button of my app is calling the intent) or is it really a bug in the ZXIng library?

Android :: Preferred Developer Android Phone For Using The ZXing Library

Sep 9, 2010

Using this library, ZXing, we have a project at school in which we'll implement a inventory system using Android phones.

We aim to use an Android phone to be a inexpensive replacement to this:

I've read some of the warnings on the FAQ for certain phones. Is there a specific phone that Android developers prefer (with use of the ZXing library in mind)? We have to buy the phone ourselves, so we would prefer not to buy the wrong phone!

General :: How To Decrypt Encrypted Tablet

Apr 14, 2012

I purchased an Acer Iconia A200. It took the system upgrade to Ice Cream Sandwich without any problems. After upgrading, I chose to apply the "Encrypt Tablet" feature -- and now I regret that choice. The tablet won't take any more system updates, and apparently it can't ever successfully follow through on a factory reset.

Any way to decrypt an encrypted Ice Cream Sandwich tablet -- or at least if there's a way to factory reset it successfully?

General :: Users With Encrypted Phones

Aug 14, 2012

From the online articles and the encryption description i was left with the impression that i will need to enter the password only on boot.Well appears that once encrypted the only active unlock options become, face unlock, pin and password.All take too long for my daily use, and since you don't have to use the encryption password for unlocking (the phone is decrypted on boot) but other options like face unlock, why we can't unlock with the normal slider screen or at least pattern unlock?Is there a way to go around it and enable the slider unlock on an encrypted phone?

i know that decreases the security, but knowing that if i lose my phone, chances are the battery will die, and they will need to decrypt it then...

General :: 7zip Unpacking Encrypted Archives Without UI?

Apr 7, 2014

how the android OS is built and what goes on behind the scene. Most of my experience comes from Linux and programming in Python.

Now to my question, I have written a program in Python that I am currently running on my Linux devices to unpack encrypted (AES256) 7-zip files. I would like to be able to run this program on my Android devices as well. I need a third party application to unpack the 7-zip files on android in a command line like environment. The program needs to run in the background, no user interaction at all.

On my Linux devices I simply have 7-zip installed and then run a os.system("7zip command") to unpack my files.
