Can someone help me modify this code?

Hi everyone, I have some code that I got from http://developer.appcelerator.com/blog/2011/09/sharing-project-assets-with-android-intents.html to view pdf's in Android.

Right now, it makes you push a button to view the pdf. Is there a way to make it automatically load the pdf without the use of the button? Here's the code I'm using.

Ti.UI.setBackgroundColor('#222');
 
var win = Ti.UI.createWindow({
    navBarHidden: true,
    exitOnClose: true
});
 
 
var button = Ti.UI.createButton({
    title: 'open pdf',
    height: '60dp',
    width: '120dp',
    top: '140dp'
});
 
 
var appFilePath = '12ALTAAGENG.pdf';
var appFile = Ti.Filesystem.getFile(appFilePath);
var tmpFile = undefined,
    newPath = undefined;
 
if (Ti.Filesystem.isExternalStoragePresent()) {
    tmpFile = Ti.Filesystem.createTempFile();
    newPath = tmpFile.nativePath + '.pdf';
    tmpFile.move(newPath);
    tmpFile = Ti.Filesystem.getFile(newPath);
    tmpFile.write(appFile.read());
} else {
    Ti.API.error('No external storage present');
}
 
 
button.addEventListener('click', function(e) {
    if (tmpFile) {
        var intent = Ti.Android.createIntent({
            action: Ti.Android.ACTION_VIEW,
            type: "application/pdf",
            data: tmpFile.nativePath
        });
 
        try {
            Ti.Android.currentActivity.startActivity(intent);
        } catch(e) {
            Ti.API.debug(e);
            alert('No apps PDF apps installed!');
        }
    }
});
 
 
win.addEventListener('close', function(e) {
    tmpFile.deleteFile();
});
 
win.add(button);
win.open();

Thanks.

Try openStream( Number mode, String path )

I seem to have figured it out. Combining the code from the link above and some code I was using before, I came up with this.

var appFilePath = '12ALTAAGENG.pdf';
var appFile = Ti.Filesystem.getFile(appFilePath);
var tmpFile = undefined,
    newPath = undefined;
 
if (Ti.Filesystem.isExternalStoragePresent()) {
    tmpFile = Ti.Filesystem.createTempFile();
    newPath = tmpFile.nativePath + '.pdf';
    tmpFile.move(newPath);
    tmpFile = Ti.Filesystem.getFile(newPath);
    tmpFile.write(appFile.read());
} else {
    Ti.API.error('No external storage present');
}
 
try {
    var f = Ti.Filesystem.getFile(tmpFile);
    Ti.Android.currentActivity.startActivity(Ti.Android.createIntent({
        action: Ti.Android.ACTION_VIEW,
        type: 'application/pdf',
        data: tmpFile.nativePath
    }));
}
 
catch (err) {
    var alertDialog = Titanium.UI.createAlertDialog({
        title: 'No PDF Viewer',
        message: 'We tried to open a PDF but failed. Do you want to search the marketplace for a PDF viewer?',
        buttonNames: ['Yes','No'],
        cancel: 1
    });
    alertDialog.show();
    alertDialog.addEventListener('click', function(evt) {
        if (evt.index == 0) {
            Ti.Platform.openURL('http://search?q=pdf');
        }
    });
}

It's working the way I want it, but if anyone has a more efficient way to code this, I'm all ears.
