There is no way you can update the apk with other keystore.
Did you created any keystore certificate or you used default certificate of 
android studio or eclipse?

Then there can only be one case that is preventing execution of the code ie
check for return statement or system.exit or if block is inside any loop
check for break..just dry run it put appropriate debug pointers...

Re: [android-developers] Re: SharedPreferences doesn't work for my app but other apps is ok.

[VISHAL TIKKU]

Its okay no issues.Test case to test this functionality are as
 follows:
1. In your code write an else block in which provide a toast message and
also in your if block provide a different toast message.
2. Clear yours app's cache and data from settings of the phone.
3. Run your code and see if toast comes from if block first.
4. Close your app and run it again see if toast is coming from else block.

if points 3 & 4 is achieved then there is no problem in your code, if else
block is getting executed when you run your app for the first time find
whether your shared preference "rememberme"  is been used in any other
class where shared preference is getting updated.

See if it works.

Happy Coding!

[android-developers] Re: determining when users uninstall my app

[VISHAL TIKKU]

You can track it through yourself if you don't have standalone application 
ie if your app requires any server communication.Through server 
communication you can maintain the number of users that are using your 
application and sending time spent(use CountDownTimer) on each page to the 
server and maintaining in database with respect to the user can help you 
trace how much a user is exploring your application in the end the above 
solution will work if you are maintaining user records on your server.

[android-developers] Re: Make simple app UI

[VISHAL TIKKU]

You can go by creating layouts in XML also you would need to define size 
for layouts and would recommend doing dynamically from activity by taking 
device width and height, divide the view accordingly and it will make the 
view compatible with all the devices.
Also for tab widget you need to have png for curved line as depicted in 
image you shared and placing it accordingly with the tab view.For this type 
of UI go for RelativeLayout as you can place objects relative to a view 
easily.
Happy Coding!
