Can't Enable "GL_EXT_shader_io_blocks" in OpenGL ES 3.0

I am using OpenGL ES 3.0 with Android, and I am compiling two shaders:

vertex shader:

#version 300 es
#extension GL_EXT_shader_io_blocks : enable

layout (location = 0) in vec2 position;
layout (location = 1) in vec4 color;
layout (location = 2) in vec2 uv;

uniform mat4 pr_matrix;
uniform mat4 vw_matrix;
uniform mat4 ml_matrix;

out DATA {
    vec2 position;
    vec4 color;
    vec2 uv;
} vs_out;

void main() {
    gl_Position = pr_matrix * vw_matrix * ml_matrix * vec4(position, 0.0, 1.0);
    vs_out.position = position;
    vs_out.color = color;
    vs_out.uv = uv;
}

fragment shader:

#version 300 es
#extension GL_EXT_shader_io_blocks : enable

layout (location = 0) out vec4 color;

uniform sampler2D tex;

in DATA {
    vec2 position;
    vec4 color;
    vec2 uv;
} frag_in;

void main() {
    float dist = length(frag_in.position);
    color = frag_in.color;
}

Even though I am enabling the GL_EXT_shader_io_blocks extension for both shaders, I get the following error:

ERROR: 0:12: 'DATA' : requires extension GL_EXT_shader_io_blocks to be enabled 
ERROR: 1 compilation errors.  No code generated.

ERROR: 0:8: 'DATA' : requires extension GL_EXT_shader_io_blocks to be enabled 
ERROR: 1 compilation errors.  No code generated.

I also tried 

#extension GL_EXT_shader_io_blocks : require

which didn't work either.

As stated in the extension specification, the IO Blocks extension requires OpenGL ES 3.10 Shading Language.

Try using #version 310 es.
