Processing on Android for GoogleCardboard

Hello,

I tried to adapt the initial code to my processing project but it triggered the following errors:

FATAL EXCEPTION: GLThread 1873 Process: processing.test.androidproj, PID: 14032 java.lang.NullPointerException at processing.opengl.PGLES.texParameterf(Unknown Source) at processing.opengl.Texture.allocate(Unknown Source) at processing.opengl.Texture.init(Unknown Source) at processing.opengl.Texture.(Unknown Source) at processing.opengl.FontTexture.addTexture(Unknown Source) at processing.opengl.FontTexture.initTexture(Unknown Source) at processing.opengl.FontTexture.(Unknown Source) at processing.opengl.PGraphicsOpenGL.textLineImpl(Unknown Source) at processing.core.PGraphics.textLineAlignImpl(Unknown Source) at processing.core.PGraphics.text(Unknown Source) at processing.core.PGraphics.text(Unknown Source) at processing.test.androidproj.androidproj.draw(androidproj.java:149) at processing.core.PApplet.handleDraw(Unknown Source) at processing.opengl.PGLES$AndroidRenderer.onDrawFrame(Unknown Source) at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1532) at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1249)

Do you know why this happened? How can I fix this?

Thank you for the help
