title: Where are the error messages of compiling OpenGL shaders in Android Studio?
body: <p>I am using GLSL to write my shaders in and Android application using Android Studio.</p>
  
  <p>Now the shader DOES contain an error. But where can I find the error messages in Android studio?</p>
  
  <p>I am using the example in Android developer guide:</p>
  
  <pre><code>    // create empty OpenGL ES Program
      mProgram = GLES20.glCreateProgram();
  
      // add the vertex shader to program
      GLES20.glAttachShader(mProgram, vertexShader);
  
      // add the fragment shader to program
      GLES20.glAttachShader(mProgram, fragmentShader);
  
      // creates OpenGL ES program executables
      GLES20.glLinkProgram(mProgram);
  </code></pre>
