How to set the save path for the downloaded file so that the file manager can be opened and you can specify the folder to save?
I learned how to download files, display the process, open after loading. Learned to save by setting the path in the form:
output = new FileOutputStream("/sdcard/my_downloads8.pdf"); File in pdf format.
An example taken from here .
Thanks for any info. All my code
public class MainActivity extends AppCompatActivity { ProgressDialog mProgressDialog; //defining file name and url // public String fileName = "человек бренд"; // public String fileURL = "https://drive.google.com/uc?export=download&id=0B_Vo7XGE5XkUTXUwbDdQY1BKT2c"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); mProgressDialog = new ProgressDialog(MainActivity.this); mProgressDialog.setMessage("A message"); mProgressDialog.setIndeterminate(true); mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); mProgressDialog.setCancelable(true); FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // execute this when the downloader must be fired final DownloadTask downloadTask = new DownloadTask(MainActivity.this); downloadTask.execute("https://drive.google.com/uc?export=download&id=0B_Vo7XGE5XkUTXUwbDdQY1BKT2c"); mProgressDialog.setOnCancelListener(new DialogInterface.OnCancelListener() { @Override public void onCancel(DialogInterface dialog) { downloadTask.cancel(true); } }); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here.
