just replace, String FRAGMENT_SHADER_EXT_FILT final-variable with,

private static final String FRAGMENT_SHADER_EXT_FILT =
"#extension GL_OES_EGL_image_external : require\n" +
"#define KERNEL_SIZE " + KERNEL_SIZE + "\n" +
"precision highp float;\n" +
"varying vec2 vTextureCoord;\n" +
"uniform samplerExternalOES sTexture;\n" +
"uniform float uKernel[KERNEL_SIZE];\n" +
"uniform vec2 uTexOffset[KERNEL_SIZE];\n" +
"uniform float uColorAdjust;\n" +
"void main() {\n" +
" int i = 0;\n" +
" vec4 sum = vec4(0.0);\n" +
/* " if (vTextureCoord.x < vTextureCoord.y - 0.005) {\n" +/
" for (i = 0; i < KERNEL_SIZE; i++) {\n" +
" vec4 texc = texture2D(sTexture, vTextureCoord + uTexOffset[i]);\n" +
" sum += texc * uKernel[i];\n" +
" }\n" +
" sum += uColorAdjust;\n" +
/" } else if (vTextureCoord.x > vTextureCoord.y + 0.005) {\n" +
" sum = texture2D(sTexture, vTextureCoord);\n" +
" } else {\n" +
" sum.r = 1.0;\n" +
" }\n" +*/
" gl_FragColor = sum;\n" +
"}\n";
