Thousands of apps are being released to major app stores every day. Yet, most of them wither before they even have a chance to bloom.
The effort, money, and time that is put into developing apps are enormous. Once you’ve got a lot of negative feedback from the users, there will be hardly any second chance given to prove the worth of your app. So ensuring security should be a major step taken by app development companies.
what are some of the most common security vulnerabilities of android app development
Hi All ;
I developed an Android application which is a custom keyboard with a custom font.
I developed the keyboard successfully but I'm stuck for changing the font. How can I install and setup a custom font in my Android device ? I need to setup the font with my keyboard in the same application.
I used the iFont application to install the font on the device without root access. I searched if I could find code do the same function than the iFont application. How can I install a font programmatically?

<pre lang="C#">Dialing a USSD code from a custom activity is straight forward using a DIAL or CALL intent, but listening to the returned result is not due to Android not having proper support for intercepting USSD calls within the platform, but partial though undocumented support exists within the native dialer application.
As a start, look at the PhoneUtils class in the Android source code. The link is for 4.0.3 but I believe this partial support has been present since 2.3.
Specifically, looking at line 217, an intent with the name “com.android.ussd.IExtendedNetworkService” is being composed. So what you need to do is implement your own service that responds to that intent. The service needs to be implemented according to the IExtendedNetworkService.aidl which is a part of the Android framework.
The aidl exposes several functions but the one we care about is the getUserMessage(text) function in that service. The text is the final value returned from the USSD call.
Since the service is binded on by PhoneUtils, then you need to start the service at phone boot up. It also means that any modification to the service will need a phone reboot.
Returning null from getUserMessage will suppress the dialer from showing the USSD result but there’s no way to completely hide the dialer.
You can also use the other functions to change the text shown while the call is in progress.
This doesn’t seem to work on USSD prompts(menus), only on final results.</pre>
