Get Started with Java File Format APIs
You can easily use Aspose.Total for Android via Java directly from Maven and install Aspose.PDF for Android via Java and Aspose.Slides for Android via Java in your applications.
Alternatively, you can get a ZIP file from downloads .
// load CGM file with an instance of Document class
Document document = new Document("template.cgm");
// save CGM as PPTX format
document.save("PptxOutput.pptx", SaveFormat.Pptx);
// instantiate a Presentation object that represents a PPTX file
Presentation presentation = new Presentation("PptxOutput.pptx");
// save the presentation as Pptm format
presentation.save("output.pptm", SaveFormat.Pptm);
Open Password Protected CGM File in Android Apps
While loading CGM file format, your document might be password protected. Aspose.PDF for Android via Java allows you open encrypted documents as well. In order to open the encrypted file, you can initialize new instance of the Document class and pass filename and password as arguments.

// instantiate a Presentation object that represents a PPTM file
Presentation presentation = new Presentation("output.pptm");
// access the first slide
ISlide sld = pres.getSlides().get_Item(0);
// create a full scale image
BufferedImage image = sld.getThumbnail(1f, 1f);
// save the image to disk in PNG format
ImageIO.write(image, "PNG", new java.io.File("Thumbnail_out.png"));
