Usage

From source file:Triangle.java

    int fragmentShader = loadShader(GLES20.GL_FRAGMENT_SHADER, fragmentShaderCode);

    GLES20.glAttachShader(mProgram, fragmentShader);
    GLES20.glLinkProgram(mProgram);/*  w ww .  j ava  2 s .  com*/

    ByteBuffer bb = ByteBuffer.allocateDirect(triangleCoords.length * 4);
    bb.order(ByteOrder.nativeOrder());

    vertexBuffer = bb.asFloatBuffer();
    vertexBuffer.put(triangleCoords);
    vertexBuffer.position(0);
