Android :: How To Match System Signature With Application Signature On Android Emulator?

Aug 24, 2010

I need to create a Robotium application that would use Settings application to turn ON/OFF WIFi from menu Settings->Wireless & networks->Wi-Fi.I managed to find some sample code here that demonstrates how to launch application by having apk file only.The problem is that my Robotium application should have the same signature with the (system) Settings application.Can I somehow make it work with the Android Emulator?If I compile an Android phone image, how can I use the Android system signature with my application?

Android :: Fails Installing Apk To Emulator Due To Mis-matched Signature

Feb 2, 2009

I made some modifications in cupcake camera source code using Eclipse, and try to load to emulator for testing. But it fails installing the apk to the emulator due to the mis-matched signature of android,media, which is set as share user id in manifest.xml. The android,media is pre-built in the emulator. does any one know how those preload packages are signed and how to set correct signature (or keystore) in Eclipse?

General :: Recompile System APK Using ONLY APKTool While Keeping Signature?

May 17, 2012

I don't want to use APK Multi-Tools or APK_Manager or whatever. I want to know exactly what those tools are doing in order to recompile the system apk while keeping the original signature.

What I initially did...

apktool d "%~dpnx1.apk" "%~dpnx1"

...modify files here...

apktool b "%~dpnx1" "%~dpnx1.apk"

But obviously that's unsigned. I need to sign it, but I want to use the original signature, which I'm guessing is the META-INF stuff, right? So I attempted this...

apktool d "%~dpnx1.apk" "%~dpnx1"
7za x -o"%~dpnx1-signature" "%~dpnx1.apk" META-INF -r

...modify files here...

apktool b "%~dpnx1" "%~dpnx1.apk"
7za a -tzip "%~dpnx1.apk" "%~dpnx1-signature/*" -mx9

You'll notice I now use 7-Zip to pull out META-INF from the original APK and then insert it back into the recompiled one afterwards.

The only other thing I can think of would be to go with my first method, but then use 7-zip to pull out the compiled files from the unsigned apk and insert them into the signed apk. I haven't tried that yet, but it will be the next one I go with. Every time this fails, though, I have to do a nandroid restore.

For those interested, after running "apktool b" (to build/compile), ignore the output zip. Instead go into the source directory and there is now a build directory. In that is an apk directory. Simply add your changed files to the original untouched APK (if you modified any XML files, then replace resources.arsc; if you added anything to smali, then replace classes.dex; if you added any XML files, then you need to include those as well; for me, i copied resources.arsc, classes.dex, and one new XML file). I used the following command:

zip -9 ..SystemUI.apk reslayoutstatus_bar.xml classes.dex resources.arsc

I use zip instead of 7za for cosmetic reasons. You can also use "7za a -tzip etc..." if you want.

Android :: Possible To Check .apk Signature?

Oct 6, 2010

I haven't really concerned myself with app piracy; I only have one app under my belt for Android, it's in beta and it's free. I'm about to start development on another app and looking to use ProGuard for obfuscation and LVL as I would like to make it a paid app, and I've been wondering something ever since the news that LVL had been circumvented months ago.Is it possible to check the .apk's signature from within the API? If not currently, perhaps Google might add some code to Android itself or to the API to enable LVL to make sure that the.apk signature matches the signature that Android Market already has on file?

Android :: Signature Capture App?

May 21, 2010

i had an interview this morning for a job, and have an opportunity to earna great deal of brownie points with the business owners.They were thinking of purchasing some sort of electronic signature capture device (like fedex or UPS has when you sign for a package) for invoices.. BUT.I also mentioned my Droid Eris and how it can do so much. Turns out, both of the Owners have DROIDs lol.Anyways.. I want to know if anyone has seen some sort of application that can capture signatures, and either save an image to be emailed, or email directly from the app.OR does anyone know a DEV that could create something as simple as this, that I can talk to and relay updates on the APP to the owners of this company.They seemed really interested in it, and I'm pretty positive it will show a good bit of initiative in saving their company money from the get-go (on my part)

General :: How To Get ReponseData And Signature For Android LVL

Nov 8, 2013

I try to implement a server side verification of an application with LVL library. I use this php code : [URL] .... In the file sample/verify.php, I have two lines to complete :

$responseData = '';
$signature = '';

I see in the google LVL that there is a function called verify which has these parameters :

public void verify(PublicKey publicKey, int responseCode, String signedData, String signature);

But I don't understand where this function is called and by what function. Also I want to get this datas. How can I do that ?

Android :: Upgrading To 1.5 - Radio's Signature Error

Jun 6, 2009

My phone was updated to 1.5 this week. I have been waiting to update my development environment, until the phone was upgraded. The ide started out smoothly, I even updated my new Colorthon program library and posted the compiled version on the marketplace.

Next I decided to upgrade Radio's Exercise Buddy. Got a signature error. I worked around it by giving it a new namespace, but this is far from ideal, because now my users will have to use a migration tool, to bring their data over. Is there a better way to do this? Also, If I change the namespace, can I still have my paid users get a free upgrade? Also, I know that many developer's have upgraded earlier, but I wanted to wait until I had the updated phone. If this is a common problem, please refer me to the thread to read.

Android : Way To Change Signature For Camera.setPreviewDisplay In 1.5?

Apr 15, 2009

Camera.setPreviewDisplay() now throws an IOException. Is there a reason this had to be a checked exception (looking at the source code I can't an see an immediate one)? Or is it just an oversight that will be fixed before releasing the final SDK? The consequence is that one cannot have code that will compile for both 1.1 and 1.5 without doing something ugly like adding a blanket try/catch.

Android :: Error / LicenseValidator(4883) Signature Verification Failed

Aug 4, 2010

I'm having a problem with the LVL in one of my apps. Here are the projects in my eclipse workspace: com_android_vending_licensing - standard LVL my_app_1 my_app_2 my_app_3 All three of the apps use the same licensing library project (including the same SALT), and share the same code in their main activities for checking the license. But when testing, one of the apps continuously fails the license request and the others respond correctly depending on what test response I set in the market "Edit Profile" page. The error I get in logcat is: 08-04 15:20:20.863: ERROR/LicenseValidator(4883): Signature verification failed. And the dontAllow() function of the LicenseCheckerCallback is run. This error message originates from line 104 of in the licensing library. I've done some debugging and the responseCode is set to LICENSED (see line 94 of
