Open a selected file (image, pdf, ...) programmatically from my Android Application?

Question

I'm working on an Android application which should be able to open a selected file from a specific folder.

I already tried this, but after selecting which application I want to open it, I got this message:

Impossible loading

After trying a lot of thread 1 and thread 2, I use these lines of code to do it:

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("/mnt/sdcard/xxx/xxx/Pictures/xxx.jpg"), "image/*");
myContext.startActivity(intent);

How can I figure this out?

Answer 1

Try the below code. I am using this code for opening a PDF file. You can use it for other files also.

File file = new File(Environment.getExternalStorageDirectory(),
                     "Report.pdf");
Uri path = Uri.fromFile(file);
Intent pdfOpenintent = new Intent(Intent.ACTION_VIEW);
pdfOpenintent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
pdfOpenintent.setDataAndType(path, "application/pdf");
try {
    startActivity(pdfOpenintent);
}
catch (ActivityNotFoundException e) {

}

If you want to open files, you can change the setDataAndType(path, "application/pdf"). If you want to open different files with the same intent, you can use Intent.createChooser(intent, "Open in...");. For more information, look at How to make an intent with multiple actions.
