File not exist occurs only for XLSX file in android - android

I have trying to open XLSX file in android using intent filter to select existing XLSX reader application but always getting file not found exception. The same code works fine for XLS file. I added WRITE_EXTERNAL_STORAGE permission in manifest and file path being correct only. File also available in SD Card. My tablet have sheet to go and OfficeSuite application to read XLSX files. Even i can able to open my XLSX file by clicking on it. But trying to open via my application gives problem. For XLSX file my code always goes to else part. Thanks in advance.
private void openSpreadSheet(String fileCompletePath) {
File file = new File(fileCompletePath);
if (file.exists()) {
try {
Log.d(TAG, "File exist");
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/vnd.ms-excel");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
Toast.makeText(this,
"No application found to display spread sheet.",
Toast.LENGTH_SHORT).show();
}
} else {
Log.d(TAG, "File not exist");
}
}
If i remove if condition, then intent filter asked for choose application after choosing application, that selected application shows this error File not found(/Duplicate.xlsx:open failed:ENOENT(No such file or directory)).
Found Solution
Issue comes because I gave wrong file path.

Android open PDF from URI starting content

I am trying to open up PDF using intent that takes the following:
Here is the code that I have:
Intent intent = new Intent(Intent.ActionVIEW)
intent.setDataAndType(Uri.parse("CONTENTURI + FILENAME","application/pdf"
try { startActivity(intent)} catch excpetion and so on.
It pops up with whatever applications I have installed, from Adobe Reader, Google PDF reader, POLARIS(as I am using Galaxy Tab 3 for testing), and none of those work. Each say unsupported document.
Does download and show the right solution in this case, or any ideas? Thanks in advance!
Following code triggers the VIEW action for pdf files (open the default PDF viewer, choose between applications capable to view PDFs or get an error if you don't have any installed).
File file = new File("your pdf path here");
if (file.exists()) {
Uri pdfPath = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(pdfPath, "application/pdf");
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
//if user doesn't have pdf reader instructing to download a pdf reader
}
}
NOTE: The PDF should not be saved local to application, or else the third party app won't have access. You should use media location.

if section not working....plz help..
You need to write the your PDF file present in your app's res folder to sdcard. So that other apps can read and open it.
As in res folder file is locally available to your app only. and you are Throwing an intent for other apps to open that pdf which is not accessable to them. so remove your if check, write your pfd from res to sdcard and pass that file's uri to the intent.

How do I read a csv file that is on the downloads directory of a mobile device, for an Android application

How do we code to get the "Open from" dialog, on an Android device?
I can find many source code examples for reading a csv file, especially when located in the res\raw directory, but I could find no example of how to have an Android app issue a dialog to read the Downloads directory and select a csv file stored in it.
Thanks a lot!!!
I found hints to the solution in an article entitled Android Import excel into Sqlite Database Part 1
To get that dialog:
Intent fileIntent = new Intent(Intent.ACTION_GET_CONTENT);
fileIntent.setType("text/csv")
try {
startActivityForResult(fileIntent, REQUEST_CODE);
} catch (ActivityNotFoundException e) {
Toast.makeText(MainActivity.this, "No app found for importing the file.", Toast.LENGTH_LONG).show();
}
where REQUEST_CODE is 1.
You can then later on access the selected file by:
String filepath = data.getData().getPath();

I want to read the pdf files from assets or raw folder in android

when i m run it i m getting this error like "File or folder not found" and " file dosnt exit or can't be opened "..
This is the code sir..
i want the how to view pdf files from assets or in raw folder sir.. its very imp for my project try to slove my problem sir.. and tell me clearly i m new to android sir.. can any one send me code cloerly how to do it..
enter code here
Uri path = Uri.parse("android.resource:///com.example.pratice/raw/em");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e){
Toast.makeText(this, "NO Viewer", Toast.LENGTH_SHORT).show();
}
Few, if any, Android PDF viewer apps will honor the android.resource scheme, and there is no Uri scheme for assets.
If you want to serve up a PDF file, copy it from assets or a raw resource into internal storage, then use FileProvider to make it available to other apps. Here is a sample application that does this.

Pdf files as part of Android .apk

I have to build an Android application which shows a list of pdf files. These pdf files should be secured, in other words - the user of the app should not be able to get a copy of the pdf content by any means (copy/cut/print...etc). My questions now are
How should I ship the content of the pdf file along with .apk file.
If we send the content of the file in a diff format (raw/byte code), how should I convert the file back to pdf and where should I place the file on the installed machine such that it is secure.
FYI, I will be locking down current version of Adobe Redaer as the pdf viewer to view the pdf files as it doesn't allow copy/paste/print.
This is the first Android app that I am developing. So, I'm a kind of Android newbie. Any help would be greatly appreciated.
Thanks,
Navin
Probably you should store it in the res/raw folder
You can copy this(these) pdf file(s) into assets folder, thus your files will be the part of your application and can not be accessible outside, and you can also treat them as normal files (i.e. open with any pdf viewer in your case). Whenever you want to get access to context file you can call context.getAssets() .
Hope this information helps.
Update : Here is the code I am using to open a file in downloads directory, this code can open the pdf file in any compatible pdf reader if installed on phone, Tested with Adobe Reader. You will need a URI of the pdf file in assets folder to run the code.
String fileName = pdfUrl.substring(pdfUrl.lastIndexOf("/"));
Log.i("fileName", "" + fileName);
File file = new File("/sdcard/download" + fileName);
// File file = new
// File("/sdcard/download/airtel_latest000.mp3");
Intent intent;
if (file.exists()) {
Uri path = Uri.fromFile(file);
intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
downloaded = true;
} else {
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(pdfUrl));
downloaded = false;
}
try {
startActivityForResult(intent, 5);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
