Unable to open pdf client on button click - android

Here is my button click code:
private View.OnClickListener onButton1=new View.OnClickListener() {
public void onClick(View v){
copyAssets();
File rootDir = Environment.getExternalStorageDirectory();
File file = new File(rootDir + "/sdcard/" +"save.pdf");
if(file.exists())
{
// do action here
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.fromFile(file));
intent.setType("application/pdf");
startActivity(intent);
}
else {
Toast.makeText(getApplicationContext(), "File does not exist", Toast.LENGTH_LONG).show();
}
}
};
copyAssets() is a function by which I copy the file from my assets folder to my SD-Card and it is working as I checked on my device, but I am unable to open it when I click the button. My file is named as save.pdf on the SD-Card

you can read pdf file from SDCard by giving the path as follows:
File pdfFile = new File(path);
if(pdfFile.exists())
{
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try
{
startActivity(pdfIntent);
}
catch(ActivityNotFoundException e)
{
Toast.makeText(uractivity.this, "File does not exist", Toast.LENGTH_LONG).show();
}
}

Unable to open PDF file through intent programmatically in android

I have an app where on button click, access should be provided to browse and open the PDF files stored in the internal memory of the device.I tried various codes but i get an toast saying "Cannot display PDF". I don't get any errors in logs. I use android version 7.0 device. Attached my code below: please help:
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(intent);
I have included this in Oncreate:
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
This is how called the method:
linear_pdf.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pdf.setTextColor(getActivity().getResources().getColor(R.color.colorWhite));
openPdf(getContext(), Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
communication.dismiss();
}
});
Try this one...
public void openPdf(Context context, String path){
File file = new File(path);
if (file.exists()) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
PackageManager pm = context.getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.setType("application/pdf");
Intent openInChooser = Intent.createChooser(intent, "Choose");
List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
if (resInfo.size() > 0) {
try {
context.startActivity(openInChooser);
} catch (Throwable throwable) {
Toast.makeText(context, "PDF apps are not installed", Toast.LENGTH_SHORT).show();
// PDF apps are not installed
}
} else {
Toast.makeText(context, "PDF apps are not installed", Toast.LENGTH_SHORT).show();
}
}
}
Call this method:
openPdf(getApplicationContext(), Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
For opening one specific file:
File pdfFile = new File(Environment.getExternalStorageDirectory() + "/your_directory/" + "your_file_name" + ".pdf");
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try{
startActivity(pdfIntent);
}catch(ActivityNotFoundException e){
Toast.makeText(getContext(), "No required app", Toast.LENGTH_SHORT).show();
}
Check directory, this one works.
For opening pdf file from local storage add prefix in url.
private void openPdf(File file) {
try {
String url = file.getAbsolutePath();
String u = "file:///" + url;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(u));
startActivity(i);
} catch (Exception e) {
e.printStackTrace();
}
}

Android open XLSX file

I'm trying to open an XLSX file within my Android App.
I'm aware that the Intent type I have to fire is application/excel, but despite I've installed Google Sheets, my code says that no application can open my excel file.
This is the code I use to fire the Intent:
private void openXLS(){
File xls = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS), "prova.xlsx");
Uri path = Uri.fromFile(xls);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/excel");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
context.startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(context, "No Application available to view XLS", Toast.LENGTH_SHORT).show();
}
}
Note: prova.xlsx exists, and I'm able to reach it and open it.
SOLVED
Using the MIME type application/vnd.ms-excel, *.xls and *.xlsx files can be opened.
private void openXLS(final String path) {
File file = new File(path);
Uri uri ;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
uri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
} else {
uri = Uri.fromFile(file);
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setDataAndType(path, "application/vnd.ms-excel");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "Application not found", Toast.LENGTH_SHORT).show();
}
}

Opening pdf in android/kindle app

I want to open a pdf from a website onto an app i'm making for the kindle and android.
I think my code is right but it can't find my file and I wasn't sure if anyone knew if I should be formatting the file different since it's technically a website....
Any input would be greatly appreciated. Here's what I have so far:
Button OpenPDF = (Button) findViewById(R.id.button1);
OpenPDF.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
File pdfFile = new File("http://thisisthewebsitewithpdf.pdf");
if(pdfFile.exists()) //EXCEPTION HERE. pdfFile doesn't exist!
{
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try
{
startActivity(pdfIntent);
}
catch(ActivityNotFoundException e)
{
Toast.makeText(PDFActivity.this, "No Application available to view pdf", Toast.LENGTH_LONG).show();
}
}
you can download the pdf to your sdcard and then open it using this activitty:
public class OpenPdf extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.OpenPdfButton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
File file = new File("/sdcard/example.pdf");
if (file.exists()) {
Uri path = Uri.fromFile(file);
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(OpenPdf.this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
}
}
});
}
}

you cant do that directly, you have to use Native Library for reading PDF... library may be iText, jPedal, Mupdf, Pdfbox... etc. Google it
