Titanium Android for a specific application

Question

I want to open an Android application from Titanium with Explicit intentand send him a string.

I tried the following examples, but none of them work.

var intent = Ti.Android.createIntent({
                        action: Ti.Android.ACTION_DEFAULT,
                        packageName:"com.example.new_pdf_reader"
                       //url:"com.example.new_pdf_reader"
             });
                    intent.addCategory(Ti.Android.CATEGORY_DEFAULT);
                    Ti.Android.currentActivity.startActivity(intent);

and

var shareIntent = Ti.Android.createIntent({

                                action : Ti.Android.ACTION_SEND,
                                type : "text/plain"
                        });

shareIntent.putExtra('net.sf.andpdf.extra.PDFFILENAME', "path");
Ti.Android.currentActivity.startActivity(Ti.Android.createIntent(shareIntent, "Share image"));

Answer 1

My example: PDF_reader

 var intent = Ti.Android.createIntent({
        action: Ti.Android.ACTION_SENDTO,
        data: 'com.example.new_pdf_reader',
        type:'text/plain'
    });

    intent.addCategory(Ti.Android.CATEGORY_DEFAULT);
    intent.putExtra('net.sf.andpdf.extra.PDFFILENAME', Titanium.Filesystem.get+ '/File.pdf');

    Ti.Android.currentActivity.startActivity(intent);
