can any one help me in this.

Answer 1

use %20 (for white space) in between iTunes and 20Connect.pdf .

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/iTunes%20Connect.pdf");

I think this will solve your problem

Answer 2

try out this path

File file=new File("/sdcard/iTunes Connect.pdf");

I think this will work for u

Answer 3

I think you should not use hard coded file paths. The framework will give you the base path of the area you want to save files to.

For SD card you should, use Environment.getExternalStorageDirectory()

local files you should, use Context.getFilesDir() (or Context.openFileOutput(String name, int mode), etc)

local cache you should, use Context.getCacheDir()

For emulator you can try File file=new File("mnt/sdcard/iTunes Connect.pdf");

Answer 4

I think that your emulator have not adob reader install please check first it is install or not

 File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
    Intent target = new Intent(Intent.ACTION_VIEW);
    target.setDataAndType(Uri.fromFile(file),"application/pdf");
    target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

    Intent intent = Intent.createChooser(target, "Open File");
    try {
        startActivity(intent);
    } catch (ActivityNotFoundException e) {
        // Instruct the user to install a PDF reader here, or something
    }   `enter code here`
