How to render PDF in Android

Some phones (like the Nexus One) come with a version of Quickoffice pre-installed so it may be as easy as sending the appropriate Intent once you've saved the file to the SD card.

public class OpenPdf extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button = (Button) findViewById(R.id.OpenPdfButton);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                File file = new File("/sdcard/example.pdf");

                if (file.exists()) {
                    Uri path = Uri.fromFile(file);
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setDataAndType(path, "application/pdf");
                    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

                    try {
                        startActivity(intent);
                    } 
                    catch (ActivityNotFoundException e) {
                        Toast.makeText(OpenPdf.this, 
                            "No Application Available to View PDF", 
                            Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });
    }
}

Below is the sample snippet to render from a pdf file in assets folder.

    private void openRenderer(Context context) throws IOException {
    // In this sample, we read a PDF from the assets directory.
    File file = new File(context.getCacheDir(), FILENAME);
    if (!file.exists()) {
        // Since PdfRenderer cannot handle the compressed asset file directly, we copy it into
        // the cache directory.
        InputStream asset = context.getAssets().open(FILENAME);
        FileOutputStream output = new FileOutputStream(file);
        final byte[] buffer = new byte[1024];
        int size;
        while ((size = asset.read(buffer)) != -1) {
            output.write(buffer, 0, size);
        }
        asset.close();
        output.close();
    }
    mFileDescriptor = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);
    // This is the PdfRenderer we use to render the PDF.
    if (mFileDescriptor != null) {
        mPdfRenderer = new PdfRenderer(mFileDescriptor);
    }
}
