Unable to run sketch in Android mode

[VigneshVelmurugan]

I keep getting the following error despite me trying both createFonts() and loadFonts(). Does anyone else have this issue with processing 3 in android mode? Could anyone please tell me a way to tackle this?

Thank you

Inefficient font rendering: use createFont() with a TTF/OTF instead of loadFont().

The error is an OutOfMemoryError - your app is apparently using 270 megabytes of RAM. Either you really are using that much (in which case you can't do much about it), or you're doing something wrong.

Are you by any chance calling the createFont or loadFont function on every frame (i.e. in the draw function or a function it calls)? Cause you should only be calling it once (e.g. in setup) and saving the PFont in a variable.

(equivalently, doing loadImage, createGraphics, or many more intensive things in the draw function can easily result in very high memory usage)

Thank you @dzaima , I am only calling the function in setup(). Here is my code:

`import meter.*;

Meter m1,m2,m3,m4,m5; int thumb_ang,index_ang,middle_ang,ring_ang,little_ang;

void setup() { fullScreen(); //size(displayWidth,displayHeight); background(100,200,102); thumb_ang = 20; index_ang = 20; middle_ang = 20; ring_ang = 20; little_ang = 20; // Uncomment the following two lines to see the available fonts String[] fontList = PFont.list(); printArray(fontList); PFont desFont = createFont("Montserrat-Black",32); textFont(desFont); //desFont = loadFont("Serif.bold-30.vlw"); //textFont(desFont,30);

m1 = new Meter(this, 25, 60); //(x,y) of upper left corner of the meter m1.setMeterWidth(350); m1.setTitle("Thumb"); String[] scaleLabels = {"0", "20", "40", "60", "80", "100", "120", "140", "160", "180"}; m1.setScaleLabels(scaleLabels); m1.setDisplayDigitalMeterValue(true); m1.setArcColor(color(141, 113, 178)); m1.setArcThickness(15); m1.setMaxScaleValue(180); m1.setMinInputSignal(0); m1.setMaxInputSignal(180); m1.setNeedleThickness(3);

int mx = m1.getMeterX(); int my = m1.getMeterY(); int mw = m1.getMeterWidth(); int mh = m1.getMeterHeight(); int spacing = 100;

m2 = new Meter(this,mx+mw+spacing,60); //(x,y) of upper left corner of the meter m2.setMeterWidth(350); m2.setTitleFontSize(20); m2.setTitle(" Index Finger"); m2.setScaleLabels(scaleLabels); m2.setScaleFontSize(18); m2.setDisplayDigitalMeterValue(true); m2.setArcColor(color(141,113,178)); m2.setArcThickness(15); m2.setMaxScaleValue(180); m2.setMinInputSignal(0); m2.setMaxInputSignal(180); m2.setNeedleThickness(3);

m3 = new Meter(this,mx,my+mh+spacing); //(x,y) of upper left corner of the meter m3.setMeterWidth(450); m3.setTitleFontSize(20); m3.setTitle(" Middle Finger"); m3.setScaleLabels(scaleLabels); m3.setScaleFontSize(18); m3.setDisplayDigitalMeterValue(true); m3.setArcColor(color(141,113,178)); m3.setArcThickness(15); m3.setMaxScaleValue(180); m3.setMinInputSignal(0); m3.setMaxInputSignal(180); m3.setNeedleThickness(3);

m4 = new Meter(this,mx+mw+spacing,my+mh+spacing); //(x,y) of upper left corner of the meter m4.setMeterWidth(450); m4.setTitleFontSize(20); m4.setTitle(" Ring Finger"); m4.setScaleLabels(scaleLabels); m4.setScaleFontSize(18); m4.setDisplayDigitalMeterValue(true); m4.setArcColor(color(141,113,178)); m4.setArcThickness(15); m4.setMaxScaleValue(180); m4.setMinInputSignal(0); m4.setMaxInputSignal(180); m4.setNeedleThickness(3);

m5 = new Meter(this,mx,my+2mh+2spacing); //(x,y) of upper left corner of the meter m5.setMeterWidth(450); m5.setTitleFontSize(20); m5.setTitle(" Little Finger"); m5.setScaleLabels(scaleLabels); m5.setScaleFontSize(18); m5.setDisplayDigitalMeterValue(true); m5.setArcColor(color(141,113,178)); m5.setArcThickness(15); m5.setMaxScaleValue(180); m5.setMinInputSignal(0); m5.setMaxInputSignal(180); m5.setNeedleThickness(3);

}

void draw(){

//text("Sensor Values",300,30);
m1.updateMeter(thumb_ang);
m2.updateMeter(index_ang);
m3.updateMeter(middle_ang);
m4.updateMeter(ring_ang);
m5.updateMeter(little_ang);
