Hi, I am learning Processing. I just installed P3.2.1. I have Java, Android SDK on my computer. I typed 1st sample code from book "Rapid Android Development, build rich sensor based app with Processing" by Daniel Sauter.
void setup() {size(600,400);} void draw() {ellipse(mouseX, mouseY, mouseX-pmouseX, mouseY-pmouseY);}
It works well in Java mode. Then I switched to Android mode, launched Emulator from P3.2.1, then Run in Emulator. It failed.
Is it my SDK, Java or Emulator problem? but they work well in Eclipse Android. I can run all sample codes in book "Head First, Android Development".
My P3.2.1 is in C:/Users/My Computer, SDK is in C:/Android, Java 8 is in C:/Program Files. It's Windows 7-64bit. SDK has all version Tools packages installed plus all components of API17&18 and Extras. Emulator use API 18. Please tell me what the causes problem. Thanks.
( below is error messages from console, two line codes give me so many errors)
Errors from inside Android tools, check the console
