///
// Load texture from asset
//
private int loadTextureFromAsset ( String fileName )
{
int[] textureId = new int[1];
Bitmap bitmap = null;
InputStream is = null;

try
{

is = mContext.getAssets().open ( fileName );
}
catch ( IOException ioe )
{
is = null;
}

if ( is == null )
{
return 0;
}

bitmap = BitmapFactory.decodeStream ( is );

GLES30.glGenTextures ( 1, textureId, 0 );
GLES30.glBindTexture ( GLES30.GL_TEXTURE_2D, textureId[0] );

GLUtils.texImage2D ( GLES30.GL_TEXTURE_2D, 0, bitmap, 0 );

GLES30.glTexParameteri ( GLES30.GL_TEXTURE_2D, GLES30.GL_TEXTURE_MIN_FILTER, GLES30.GL_LINEAR );
GLES30.glTexParameteri ( GLES30.GL_TEXTURE_2D, GLES30.GL_TEXTURE_MAG_FILTER, GLES30.GL_LINEAR );
GLES30.glTexParameteri ( GLES30.GL_TEXTURE_2D, GLES30.GL_TEXTURE_WRAP_S, GLES30.GL_CLAMP_TO_EDGE );
GLES30.glTexParameteri ( GLES30.GL_TEXTURE_2D, GLES30.GL_TEXTURE_WRAP_T, GLES30.GL_CLAMP_TO_EDGE );

return textureId[0];
}
