File not found error after selecting file in android
I want to open a .pdf file in my android app. Now I can view the PDF and after viewing the file, I get File not found . Error checking file exists or not ... Now after selecting the file, my selected Uri file data.getData()
is like
content://com.android.externalstorage.documents/document/6333-6131:SHIDHIN.pdf
and the path when I figure out using data.getData().getPath().toString()
is like
/document/6333-6131:SHIDHIN.pdf
Here is my code. Please help me.
// To Browse the file
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("application/pdf");
startActivityForResult(intent, PICK_FILE_REQUEST);
After selecting a file
//onActivityResult
public void onActivityResult(final int requestCode, int resultCode, Intent data) {
try {
switch (requestCode) {
case PICK_FILE_REQUEST:
if (resultCode == RESULT_OK) {
try {
Uri fileUri = data.getData();
String path = fileUri.getPath().toString();
File f = new File(path);
if (f.exists()) {
System.out.println("\n**** Uri :> "+fileUri.toString());
System.out.println("\n**** Path :> "+path.toString());
final Intent intent = new Intent(MainActivity.this, ViewPdf.class);
intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path);
startActivity(intent);
} else {
System.out.println("\n**** File Not Exist :> "+path);
}
} catch (Exception e) {
ShowDialog_Ok("Error", "Cannot Open File");
}
}
break;
}
} catch (Exception e) {
}
}

This is not an answer, but a workaround.
File file = new File("some_temp_path"); # you can also use app internal cache to store the file
FileOutputStream fos = new FileOutputStream(file);
InputStream is = context.getContentResolver().openInputStream(uri);
byte[] buffer = new byte[1024];
int len = 0;
try {
len = is.read(buffer);
while (len != -1) {
fos.write(buffer, 0, len);
len = is.read(buffer);
}
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
pass to this file the absolute path to your activity.
