              Seems to be a device specific problem....
Maybe try this:

The app just crashes
 
 
To find out why use logcat
  
  
    ADB is a command-line utility that that can be used to control your device over USB from a computer. It will allow you to install / uninstall and or view logs on your device. This could be very handy when there are issues with a specific app and you like to view the logs for information that may lead to identify the cause of error. 
In this post, we’ll discuss how to install and use ADB. 
Installation: 
ADB comes with Android SDK. However, you can download ONLY the ADB files from HERE  . Download…

              I tried to download it but it doesn't detect my phone when i try to download the driver.
             
            
              
            
                
           
          
            
            
              Is your device in developer mode with USB debugging turned on? If not, adb will not find it.
