Is it possible to develop an application which can have a read access to all the files of the phone. We plan to develop an antivirus application. I know that APK applications have for example a limited access to the /data directory.

View 1 Replies View RelatedI wrote an android application to request a scan for available WiFi signals around, using the WifiManager, then dump the results to a file. The program works fine, but this weird bug occurs. Initially I was requesting a scan every 30 seconds, and everything worked fine. I then tried to request a scan every two seconds, I get this strange bug. Everything will work fine for a few minutes, then the time between two scan requests jumps from 2 seconds to 50 seconds for no reason.
Then, for four more scans, it will scan at 2-second intervals, then skip to a 50-second interval, and it continues to do this consistently. With larger time intervals this bug does not appear. Has anyone experienced this bug before? Is there a way to prevent it? Or does Android automatically cancel scan requests if they are too frequent?
Is anyone aware of a wallet app that uses the phone's camera to scan cards for backup? i don't really relish the idea of manually entering all my card nos. and info when the camera scanner function works so well recognizing business cards.
you know, I'd like to slap my credit card on the table, open the app and scan the card. the app should recognize the cc logo (mc, visa, discover, etc), card no., exp. date and prompt me for the verification no. on the back.
the app should be able to recognize most of the card types that people typically keep in the wallets: drivers license, library card, health ins, auto ins., loyalty cards. for those that it doesn't recognize by scan, the user should be able to select from a list or enter a "custom" type.
i haven't found anything like this. does one exist?
We created a free app - VIN Barcode Scanner. I would like to know your opinion and your feedback. We are interested in a collaboration. We could offer integration to developers who has an app for search of information by VIN in Autocheck and other bases. Users would love that.
With application it is possible to scan VIN code quickly using your phone or tablet cam and then send a recieved code via sms or email. In case of integration, it is possible to search for information on the resources mentioned above. I think it is very convenient.
We are happy to offer you the following: SDK which will allow you to add VIN codes scanning into your app very easily. Many developers are using our SDK. Our SDK has a demo-mode so you can try it for free.URL....
i was wondering, say i was to do a print at home ticket, could i just pull the bar code up on my phone for the gate person to scan? seems like the prefect way to buy last minute cheap tickets on stub hub.

I am not looking to do this on pictures, but rather on pages of text. I guess I can always just email a photo, but would rather it be a pdf.
I looked in the market, and found a few, all cost $, so I am writing to see if anyone will post their experience with any of these prior to me shelling out the bucks.

Is there a way to do this? If yes, please share links.
This program worked great the first week I had it, but now it will never scan barcodes. It will scan maybe 1 out of every 10 barcodes. Is this normal? It's not scanning them and then telling me the product isn't found, it just won't scan them and sits on "Scanning barcodes, please wait." And I see tjhe little green dots running up and down the bars. I'm holding my hand as still as possible, focusing on the barcodes, and even try moving the camera in and out. I've even uninstalled and reinstalled it on my Droid X. What could be the problem?

My problem is that I can't wait 10 minutes for the result - I need them within a few seconds and thought about setting the boolean variable waiting on false as soon as I get a result, well it runs forever. Looks like nothing is received.

I am building an indoor application which continuously scans the bluetooth dongles located at different locations in a place like a mall or library.As I move in the mall with android phone in my hand I should be able to get the nearest dongle which I can connect to(Stupid Idea but I want to do something else with this).For this I should be able to continuously scan for the bluetooth devices.

Or does it just listen for beacons sent periodically by the access points?

View 2 Replies View RelatedI am currently trying to write a class in Android that will Scan for access points, calculate which access point has the best signal and then connect to that access point. So the application will be able to scan on the move and attach to new access points on the go. I have the scanning and calculation of the best signal working. But when it comes to attaching to the best access point I am having trouble. It appears that enableNetwork(netid, othersTrueFalse) is the only method for attaching to an Access point but this causes problems as from my Scan Results I am not able to get the id of the access point with the strongest signal.
This is my code:
---
public void doWifiScan(){ scanTask = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { sResults = wifiManager.scan(getBaseContext());
if(sResults!=null) Log.d("TIMER", "sResults count" + sResults.size());
ScanResult scan = wifiManager.calculateBestAP(sResults);
wifiManager.addNewAccessPoint(scan); } }); }};
t.schedule(scanTask, 3000, 30000); }
---
public ScanResult calculateBestAP(List<ScanResult> sResults){ ScanResult bestSignal = null;
for (ScanResult result : sResults) { if (bestSignal == null || WifiManager.compareSignalLevel(bestSignal.level, result.level) < 0) bestSignal = result;
} String message = String.format("%s networks found. %s is the strongest. %s is the bsid", sResults.size(), bestSignal.SSID, bestSignal.BSSID);
Log.d("sResult", message); return bestSignal; }
---
public void addNewAccessPoint(ScanResult scanResult){ WifiConfiguration wc = new WifiConfiguration();
wc.SSID = '"' + scanResult.SSID + '"';
//wc.preSharedKey = ""password""; wc.hiddenSSID = true;
wc.status = WifiConfiguration.Status.ENABLED;
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
int res = mainWifi.addNetwork(wc);
Log.d("WifiPreference", "add Network returned " + res );
boolean b = mainWifi.enableNetwork(res, false);
Log.d("WifiPreference", "enableNetwork returned " + b );
}

When I try to use addNewAccessPoint(ScanResult scanResult) it just adds another AP to the list in the settings application with the same name as the one with the best signal, so I end up with loads of duplicates and not actually attaching to them. Can anyone point me in the direction of a better solution?
I'm looking for a shopping list that will add an item when I scan a barcode, or enter it in manually, then assign a quantity.. That's really all I'm looking for.

View 16 Replies View RelatedI am currently doing my Bachelor Project concerning Android Programming.
Therefore i need a possibility to SCAN/DISCOVER Hot-Spots or WLAN's where i can connect to.
In many topics i have read, that the EMULATOR does NOT support WiFi scan with WiFiManager. I also tried using ConnectivityManager or BroadcastReceiver. But it doesn't ever work.
So my question ist the following - is it CORRECT that the emulator does not support any kind of WLAN Scan/Discovery? I need as many comments on this as possible - because only if its REALLY true, that the emulator does not provide WIFI functioanlity, then i can ask for buying a Dev Phone.
And if so, WHY there is no WiFi support within the emulator...?
I was wondering if anyone knows of an app that would allow me to scan barcodes of products at home and this becomes my shopping list? It would be nice if when i use the last of something i just scan it and through it away.

One way on my Galaxy Apollo is to plug in USB and go into storage mode, it then scans the disk (A little icon in the status bar) and the media is now there.
A more extreme way is to unmount the card and then physically remove it and re-insert (I dont have to remove the battery) and it sets off a scan.
Is there anyway to trigger a media scan from within android to make it quicker for stuff to appear?
