Android check for dependent application during installation?

Question

Hi I want to publish my application (ABC). Its an audiobook file(just for example.) wrapped as apk. When the user install this application it needs to check whether another application (XYZ) already installed or not. If not let the user know they have to install the application XYZ first before installing ABC.

Thanks in advance

Rajesh

If you know the package name of the application you are looking for you can use the PackageManager to test for the existence of an application.

try{
     ApplicationInfo info = getPackageManager()
                             .getApplicationInfo("com.myproject", 0 );
     //-- application exists
    } catch( PackageManager.NameNotFoundException e ){
     //-- application doesn't exist
}
