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?

.registers 9
.param p0, "s1" # [Landroid/content/pm/Signature;

I have a chinese console with android 2.1 (the Yinlips G18) and the recovery mod e3. I want to install an update.zip but I have this message : "E: Signature verification failed". So I want to disable the signature verification. But how I can do that safely (Modding or replace this recovery with cwm) ?

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?

Menu - Settings - Location - Enable GPS satellites
It states that enabling this will "require more battery plus view of sky"
When checked, it states "deselect to conserve battery"
So, the question is, should this be enabled?
I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used.
I'm thinking to deselect this, and selecting it at times when I need it.
So, to check or not to check?

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)

I'm looking for an app, but don't know if it exists. Basically what I want is an app that I can but a little disclaimer blurb, or something similar on and then have my customer sign it, all on the phone without the need for paper. If this could also be a part of a data base to keep track of customer info, that would be better.

I have an auto signature set up in the native Gmail app.When I compose a new email, the cursor automatically goes to the end of the signature line when I click the area to begin typing text. Does anyone know how to fix this?I would obviously like the cursor to be at the beginning of the email not at the end!

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 :
Code:
$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 ?

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.

My gmail account was easy to set up, and by going into options/settings I can edit my signature. But the option for editing/adding a signature on a none-gmail account is nowhere to be seen. What gives?

I've searched and couldn't come up with an answer. I currently have a Droid Eris so I'm running 1.5. Is it possible to add an image to an email signature? (I've already edited my signature I would just like to add a logo) If it is not possible in 1.5, is it possible in newer version of Android? (2.0?)

In Android we can get the signatures of a package with
getPackageManager().getPackageInfo(packageName, PackageManager.GET_SIGNATURES).signatures;
We can print a signature by calling
signatures.toCharsString();
How to get the same string with jarsigner or another tool from the APK file ?

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.

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?

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 LicenseValidator.java in the licensing library. I've done some debugging and the responseCode is set to LICENSED (see line 94 of LicenseValidator.java).

Pretty much self explanatory. When I use my taptalk account on my Eris, hero, and Droid it had that device in the signature but for some reason it has this weird device here.
