xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="0dp"

<Button
    android:id="@+id/button1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"

    android:backgroundTint="#1379ff" />

<Button
    android:id="@+id/Button01"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:backgroundTint="#313131" />

    android:layout_alignParentLeft="true"
    android:layout_weight="1"
    android:text="Button" />

in your layout you might have default margins specified remove them — sumit, Jun 19 '17 at 08:29
The gap in your image looks like "padding". Try to set a negative number to "android:padding" to remove this, like "-6dp" — sakiM, Jun 19 '17 at 08:40

@sakiM when i do that, it removes only "gap" on left, on right its stronger — , Jun 19 '17 at 09:08

Use negative margin to the parent layout like below.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="-5dp"
android:layout_marginRight="-5dp"

<Button
    android:id="@+id/button1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_marginBottom="34dp"
    android:backgroundTint="#1379ff" />

<Button
    android:id="@+id/Button01"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:backgroundTint="#313131" />

in your RelativeLayout you should use fill_parent and maybe it is because of it's Parent Width
