Android Upload File Ke Server

Gunakan Permission:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />

Event Button:

 buttonAttachFile.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showFileChooser();
            }
        });

File Chooser:

    private void showFileChooser() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("application/*");
        intent.addCategory(Intent.CATEGORY_OPENABLE);

        try {
            startActivityForResult(
                    Intent.createChooser(intent, "Select a File to Upload"),
                    1);
        } catch (android.content.ActivityNotFoundException ex) {
            Toast.makeText(MassageEmailActivity.this, "Please install a File Manager.",
                    Toast.LENGTH_SHORT).show();
        }
    }

Activity Result:

   @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 1) {
            if (resultCode == Activity.RESULT_OK) {
                Uri selectedFileURI = data.getData();
                File file = new File(selectedFileURI.getPath().toString());
                attachfile=  selectedFileURI.getPath().toString();

        }}}
