I have files like .doc .pdf .excel... and i want to open them externally.
I tried intent.ACTION_VIEW but it open it in the browser.
How can I open them with which ever application the user has as a default handler?
File file = new File(Globals.SAVE_PATH + filename);
openFile(file.toURI());
public void openFile(URI uri) {
Intent i = new Intent(?????);
i.setData(Uri.parse(uri.toString()));
startActivity(i);
}
You might find this article useful. The thing you must remember is that if the phone has only one app that is capable of opening the file, it will launch automatically.
Thanks for your answers but I found this method to be the easiest.
String path="File Path";
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(path);
MimeTypeMap mime = MimeTypeMap.getSingleton();
String ext=file.getName().substring(file.getName().lastIndexOf(".")+1);
String type = mime.getMimeTypeFromExtension(ext);
intent.setDataAndType(Uri.fromFile(file),type);
startActivity(intent);

how to get pdf from internal storage in android Using WebView or AnyConcept. i have to get pdf in an activity from internal storage.Can anyone of u guys let me know about this .Thank You.
String filename = null;
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent intent = Intent.createChooser(target, "Open File");
startActivity(intent);
and give pdf filename
I'm trying to open a file using another app, i.e. opening a .jpg with Gallery, .pdf with Acrobat, etc.
The problem I'm having with this is when I try to open the file in the app, it only opens the chosen app instead of opening the file within the app. I tried following Android open pdf file via Intent but I must be missing something.
public String get_mime_type(String url) {
String ext = MimeTypeMap.getFileExtensionFromUrl(url);
String mime = null;
if (ext != null) {
mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(ext);
}
return mime;
}
public void open_file(String filename) {
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), filename);
// Get URI and MIME type of file
Uri uri = Uri.fromFile(file).normalizeScheme();
String mime = get_mime_type(uri.toString());
// Open file with user selected app
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(uri);
intent.setType(mime);
context.startActivity(Intent.createChooser(intent, "Open file with"));
}
As far as I can tell, it returns the right URI and MIME type:
URI: file:///storage/emulated/0/Download/Katamari-ringtone-985279.mp3
MIME: audio/mpeg
Posting my changes here in case it can help someone else. I ended up changing the download location to an internal folder and adding a content provider.
public void open_file(String filename) {
File path = new File(getFilesDir(), "dl");
File file = new File(path, filename);
// Get URI and MIME type of file
Uri uri = FileProvider.getUriForFile(this, App.PACKAGE_NAME + ".fileprovider", file);
String mime = getContentResolver().getType(uri);
// Open file with user selected app
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(uri, mime);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}
I used this piece of code and it worked perfectly fine on android 6 and below not tested on the higher version
public void openFile(final String fileName){
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(new File(android.os.Environment.getExternalStorageDirectory()
.getAbsolutePath()+ File.separator+"/Folder/"+fileName));
intent.setDataAndType(uri, "audio/mpeg");
startActivity(intent);
}
I am using this method to open launch an Intent to open a file on Android (I've described my problems in the comments):
public static void openFile(Context context, String fileName) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// intent.setType(FileHelper.getMimeType(file)); // this doesn't work for PDF files
// opens Intent but then the chosen application doesn't open the file
intent.setType("application/pdf"); // this works correctly for PDF files
intent.setData(Uri.parse("file://" + getPath(context) + fileName));
context.startActivity(intent);
}
I would like to have a single method that would open any kind of file, without having to explicitly specify the MIME type, is that possible?
Mime type is needed to open the file i.e. we have to set Data and Type. You can use this function to open any file:
public void openFile(Context ctx,String filepath)
{
Uri ttt = Uri.parse("file://" + filepath);
Intent intent = new Intent(Intent.ACTION_VIEW);
String arr[] = filepath.split("\\.");
MimeTypeMap myMime = MimeTypeMap.getSingleton();
String mimeType = myMime.getMimeTypeFromExtension(arr[arr.length - 1]);
intent.setDataAndType(ttt, mimeType);
ctx.startActivity(intent);
}
However, there will be problem in files without extension.
I would like to open a PDF file from my android application. I've searched how to do it in internet, and it seems very easy, but it doesn't work, at least in my mobile (Sony XPeria P).
File file = ....
Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.fromFile (file));
intent.setType("application/pdf");
startActivity(intent);
When this code is executed, a window is opened asking to choose an application to show the PDF. When I choose the Adobe Reader, it's opened by no document is shown.
What I'm doing wrong?
Try this, Its working for me
//Method to open the pdf file in the PDF Viewer
public void OpenPDFFile() {
File pdfFile = new File(Environment.getExternalStorageDirectory(),"PdfFile.pdf");//File path
if (pdfFile.exists()) //Checking for the file is exist or not
{
Uri path = Uri.fromFile(pdfFile);
Intent objIntent = new Intent(Intent.ACTION_VIEW);
objIntent.setDataAndType(path, "application/pdf");
objIntent.setFlags(Intent. FLAG_ACTIVITY_CLEAR_TOP);
startActivity(objIntent);//Staring the pdf viewer
}
}
The setType("application/pdf") function removes all the previous data.
If the targetSdkVersion >= 24 we need to use file provider to get the Uri. See this post for details: https://stackoverflow.com/a/38858040/8192914
So, the final code would look something like this:
Uri pathUri = FileProvider.getUriForFile(getBaseContext(), context.getApplicationContext().getPackageName() + ".provider", finalFile);
Intent pdfViewerIntent = new Intent(Intent.ACTION_VIEW);
pdfViewerIntent.setDataAndType(pathUri, "application/pdf");
pdfViewerIntent.setFlags(Intent. FLAG_ACTIVITY_CLEAR_TOP);
pdfViewerIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(pdfViewerIntent);
I have downloaded the excel file to sdcard. want to open the file in my app and process it.
Is there any way or any intent to open an excel file in android. I
Use the below mentioned code and try:
File file = new File(Environment.getExternalStorageDirectory()+ "/filepath/" + filename);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file),"application/vnd.ms-excel");
startActivity(intent);
Use this piece of code which can be used to open arbitrary file (not only Excel).
General idea is to get based on file mime type which Intent can handle it and then start those Intent. For sure it may happen that system doesn't have any intents to handle it or may have several Intents. Anyway here's general direction:
Get mime type for given filename
public String getMimeType(String filename)
{
String extension = FileUtils.getExtension(filename);
// Let's check the official map first. Webkit has a nice extension-to-MIME map.
// Be sure to remove the first character from the extension, which is the "." character.
if (extension.length() > 0)
{
String webkitMimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension.substring(1));
if (webkitMimeType != null)
return webkitMimeType;
}
return "*/*";
}
Then get default intent which will handle given mime type
public Intent getDefaultViewIntent(Uri uri)
{
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_VIEW);
// Let's probe the intent exactly in the same way as the VIEW action
String name=(new File(uri.getPath())).getName();
intent.setDataAndType(uri, this.getMimeType(name));
final List<ResolveInfo> lri = pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
if(lri.size() > 0)
return intent;
return null;
}
And as final step just start Intent returned by getDefaultViewIntent()
Try this:
public void ouvrir(View view) {
String csvFile = "myData.xls";
File yourDir = new File(Environment.getExternalStorageDirectory()+ "/CHETEHOUNA/" + csvFile);
String davUrl = "ms-excel:ofv|u|" + yourDir.toString();
Uri uri = Uri.parse(davUrl);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
}
Uri path = Uri.fromFile(file);
Intent excelIntent = new Intent(Intent.ACTION_VIEW);
excelIntent.setDataAndType(path , "application/vnd.ms-excel");
excelIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(excelIntent);
} catch (ActivityNotFoundException e) {
Toast.makeText(EmptyBlindDocumentShow.this,"No Application available to viewExcel", Toast.LENGTH_SHORT).show();
}
Can you elaborate?
If you want to read excel file from SD card using File, here is the code
File root = Environment.getExternalStorageDirectory();
File excelFile = new File(root, "filename.xlsx");
