i want to convert ppt file into image using apache lib in android studio.
But i'm not able to read the presentation file.
In my project i have added following jar in lib folder:
poi-3.9-20121203.jar'
poi-ooxml-3.9-20121203.jar'
java-rt-jar-stubs-1.5.0 3.jar'
poi-ooxml-schemas-3.9-20121203.jar'
dom4j-1.6.1.jar'
xmlbeans-2.3.0.jar')
and added following code in onCreate(),
File sdDir = Environment.getExternalStorageDirectory();
//creating an empty presentation
File file=new File(sdDir+"TestPPT.pptx");
XMLSlideShow ppt = new XMLSlideShow(new FileInputStream(file));
//getting the dimensions and size of the slide
Dimension pgsize = ppt.getPageSize();
XSLFSlide[] slide = ppt.getSlides();
for (int i = 0; i < slide.length; i++) {
BufferedImage img = new BufferedImage(pgsize.width,
pgsize.height,BufferedImage.TYPE_INT_RGB);
Graphics2D graphics = img.createGraphics();
//clear the drawing area
graphics.setPaint(Color.white);
graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width,
pgsize.height));
//render
slide[i].draw(graphics);
}
//creating an image file as output
FileOutputStream out = new FileOutputStream("ppt_image.png");
javax.imageio.ImageIO.write(img, "png", out);
ppt.write(out);
System.out.println("Image successfully created");
out.close();
but it will gives me following error:
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException:
> java.lang.RuntimeException:
> com.android.ide.common.process.ProcessException:

> org.gradle.process.internal.ExecException: Process 'command
> '/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/java''
> finished with non-zero exit value 1
could you please help me on this error?
