Getting NoSuchMethodError with TextView Methods

Question

I am getting an NoSuchMethodError with a class that I made that extends the TextView. The only thing I did was adding it some variables and adding onLongClickListener. No more modifications.

Everything is working fine when I use my application in my android phone 4.1.2 But in my friend's phone which is 4.0.3, it throws this NoSuchMethodError.

Here is the code when i create the Class that extends the Textview:

descrip=new TextViewList(context, admin, this);
descrip.setPadding(0, 15, 0, 15);
descrip.setGravity(Gravity.CENTER);
descrip.setTextAlignment(Gravity.CENTER);                   
descrip.setText(c.getString(c.getColumnIndex("Descripcion")));
descrip.setTag(c.getString(c.getColumnIndex("ID")));
descrip.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
descrip.setHeight(LinearLayout.LayoutParams.MATCH_PARENT);
descrip.setBackground(img);
layDescripcion.addView(descrip);

First it threw the exception with setTextAlignment, then I removed it and threw it again with the setBackground method.

What is causing this error? Does that mean that my app isn't compatible with Android versions below 4.1.2? I set the minimun to be 2.2 when I created the project. And I am using android.support.v4 libraries where they are requested.

Here is the LogCat:

Answer 1

setBackground() introduced only in 16 api. Use setBackgroundDrawable() instead.

what all phone which has less than 16 api ,they will support setBackgroundDrawable()
