Hi I'm dummy at android programming, then I got some problem with building app. I tried to build apps with this xml code: `

<?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:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.ebookfrenzy.androidsample.MainActivity">

    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:inputType="textPersonName"
        android:text="@string/Namestring"
        android:ems="10"
        android:layout_above="@+id/button"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="28dp"
        android:id="@+id/editText" />

    <Button
        android:text="@string/PressMeString"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/button"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:textAllCaps="false" />
</RelativeLayout>

Then I got this error in ADV machine:

Some answers in it says "Try to set Randering to "Harware Randering", But it does not work and receive same error messages. How can I fix it?

Why this happens? I found the following:

EGL_BAD_MATCH is generated if attribute is EGL_SWAP_BEHAVIOR, value is EGL_BUFFER_PRESERVED, and the EGL_SURFACE_TYPE attribute of the EGLConfig used to create surface does not contain EGL_SWAP_BEHAVIOR_PRESERVED_BIT.

Reference: eglSurfaceAttrib The khronos group is a non-profit organisation that provides a standard OpenGL interface.

How do you solve this? In your Android Emulator you can use the Built-in (Hardware) Graphics Card. I hope this helps.
