Intent share = new Intent(Intent.ACTION_SEND);
//share.setType("image/jpeg");
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(path));
share.setPackage("com.mojang.minecraftpe");//package name of the app

} catch (Exception e) {
Log.i(TAG, "App not found.. "+e.getMessage());
}

i did it!)
File file = new File(this.getExternalFilesDir(null), "1.mcpack");
Uri photoURI = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", file);
Intent intent = new Intent(Intent.ACTION_VIEW);
// set the content type and data of the intent
intent.setDataAndType(photoURI, "application/octet-stream");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
// start the intent as a new activity
startActivity(intent);

Open with minecraft and it will open and it will day download started and if it works it will say, If it does not work it will say, Minecraft onlu supports .mcpack, .mcworld, .mctemplate on pocket edition

How to open a folder create within application in android

I am generated a folder name "tesApplication" and create a file name "testFile.csc" in it and store some date into that file. Now I want to open folder dir using new intent.
I had try below code but did not work in my case any other way to achieve this.
Uri selectedUri = Uri.parse(fileNameString);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "text/csv");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}

copy this in else
public void openFolder()
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}

Android - How do I open a file in another app via Intent?

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);
}

No activity error found when trying to install an apk from a local file

I made an application where I download an APK from an internal server, save it locally and want to prompt the user to install it.
My code is the following:
protected void onPostExecute(String path) {
Intent promptInstall = new Intent(Intent.ACTION_VIEW);
promptInstall.setDataAndType(Uri.parse(path), "application/vnd.android.package-archive");
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(promptInstall);
}
The path has the file of the APK so no problem with the download but when trying to launch the activity I get:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=/storage/sdcard/download/internalLocalApplication.apk typ=application/vnd.android.package-archive flg=0x10000000 }
at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1765)
at android.app.Instrumentation.execStartActivity(Instrumentation.java:1602)
at android.app.Activity.startActivityFromFragment(Activity.java:4340)
at android.app.Activity.startActivityFromFragment(Activity.java:4312)
at android.app.Fragment.startActivity(Fragment.java:1075)
at android.app.Fragment.startActivity(Fragment.java:1054)
What am I doing wrong here?
UPDATE:
Seems that if I change the code as follows it works! Seems that there is an issue with the Uri?
#Override
protected void onPostExecute(String path) {
Uri fileLoc = Uri.fromFile(new File(path));
Intent promptInstall = new Intent(Intent.ACTION_VIEW);
promptInstall.setDataAndType(fileLoc, "application/vnd.android.package-archive");
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(promptInstall);
}

When you call Uri.parse(path), the path argument needs to contain something like this:
file:///storage/sdcard/download/internalLocalApplication.apk
Currently your path argument doesn't contain the scheme (ie: the file:// part), which is why it can't be properly parsed.
When Android then looks for an Activity that can view this URI, It can't find one that matches, since the URI has no "scheme".

I've had this same error when trying to open an URI generated by the DownloadManager, like dm.getUriForDownloadedFile(id);
Fixed it with the following code:
Uri uri;
Cursor q = dm.query(new DownloadManager.Query().setFilterById(id));
if ( q == null ) {
Toast.makeText(AppContext,
"FAILED: Unable to read downloaded file" ,
Toast.LENGTH_LONG).show();
break;
}
q.moveToFirst();
String path = "file://" + q.getString(q.getColumnIndex(DownloadManager.COLUMN_LOCAL_FILENAME));
uri = Uri.parse(path);
Log.d(TAG,"dm query: " + path );
intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setDataAndType(uri, dm.getMimeTypeForDownloadedFile(id));

Opening pdf file programmatically is going into menu page?

How come every time i try to open a pdf file in my SDCARD using the following code, it doesn't actually open the pdf file itself, but goes into the menu of adobe reader? Is there anything wrong with my code?
Intent intent = new Intent();
File pdfFile = new File("/sdcard/sample.pdf");
Uri path = Uri.fromFile(pdfFile);
intent.setAction(Intent.ACTION_VIEW);
intent.setData(path);
intent.setType("application/pdf");
intent.setPackage("com.adobe.reader");
startActivity(intent);

No, there's nothing wrong. You've set the type to pdf and specified the package as adobe.reader. What that does is fire off an intent to launch the pdf in adobe reader. There's no way to display a pdf directly in your app without using a library (or writing code yourself) to render PDFs and display them.
Note that if you only set the type and not the package, the system will find whatever app is available to display PDFs
EDIT
You can try something like
Intent intent = new Intent(Intent.ACTION_VIEW);
File file = new File( filename );
intent.setDataAndType( Uri.fromFile( file ), "application/pdf" );
startActivity(intent);
or
Intent intent = new Intent();
intent.setPackage("com.adobe.reader");
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
startActivity(intent);

Here I am giving my pdf file name. You give your file name.
private static String FILE = Environment.getExternalStorageDirectory().getPath()+"/TestPDF.pdf";
File file = new File(FILE);
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(this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
}
