Android open PDF file via Intent
I have multiple PDF files in some folder on my SD card. I have created an application that displays all pdfs as a ListView. When I click on any pdf file it gives an error in the OfficeSuite application (UNSUPPORTED or CORRUPT FILE FORMAT). Something is wrong with the code. Here is the code.
// Code for items displayed as ListView
ListView lv;
ArrayList<String> FilesInFolder = GetFiles(Environment.getExternalStorageDirectory()
+ "/SOMEFOLDER");
lv = (ListView) findViewById(R.id.filelist);
lv.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, FilesInFolder));
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// Clicking on items
open_File();
}
});
public ArrayList<String> GetFiles(String DirectoryPath) {
ArrayList<String> MyReports = new ArrayList<String>();
File f = new File(DirectoryPath);
f.mkdirs();
File[] files = f.listFiles();
if (files.length == 0)
return null;
else {
for (int i=0; i<files.length; i++)
MyReports.add(files[i].getName());
}
return MyReports;
}
// Code for opening VIA Intent files
public void open_File(){
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/SOMEFOLDER");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent intent1 = Intent.createChooser(intent, "Open With");
try {
startActivity(intent1);
} catch (ActivityNotFoundException e) {
// Instruct the user to install a PDF reader here, or something
}
Mistake:
Corrupt or unsupported file format

I think you forgot to specify the file. Look at your code, you only pointed it to a folder but not a file. I think this is why it is telling you that it is in the wrong format, because it does not end in .pdf
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "SOMEFOLDER" + File.separator + "pdffile.pdf");
EDIT: change the methods as per your comment
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// Clicking on items
String fileName = FilesInFolder.get(position);
open_File(fileName);
}
});
public void open_File(String filename){
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/SOMEFOLDER", filename);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent intent1 = Intent.createChooser(intent, "Open With");
try {
startActivity(intent1);
} catch (ActivityNotFoundException e) {
// Instruct the user to install a PDF reader here, or something
}
