Android padding text to the left doesnt work

Im Trying to padding the text on my buttom to the left, so I can fit a simple small image before the text, but for some reason it doesnt work, and part from the text is on the icon image.

here is the xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="25dp" >

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:padding="10dp"
        android:background="@drawable/buttons_bg">

        <Button
            android:id="@+id/btPachuApps"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="4dp"
            android:padding="10dp"
            android:text="Pachu Apps Page" 
            style="@style/ButtonText"
            android:background="@drawable/button_apps"
            android:paddingTop="10dp"
            android:paddingBottom="10dp"
            android:paddingRight="10dp"
            android:paddingLeft="64dp"/>
