How to call android calculator on my app for all phones

Question

  public static final String CALCULATOR_PACKAGE =\"com.android.calculator2\";
  public static final String CALCULATOR_CLASS =\"com.android.calculator2.Calculator\";
         


        

Answer 1

You'll have to check if the default calculator package name(com.android.calculator2) is available with this:

try{
     ApplicationInfo info = getPackageManager()
                             .getApplicationInfo("com.android.calculator2", 0 );

    } catch( PackageManager.NameNotFoundException e ){
     //application doesn't exist
}

Samsung uses a lot of apps preinstalled with TouchWiz which aren't available in stock Android. Therefore if you get an Exception in the above you can check if Samsung's calculator is available. Btw I think com.android.calculator2 is not HTC specific.
