When I am browsing a file using intents it's not going to File Manager?

When i click on the Browse button i have added below code:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("*/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);
It shows FileManager in some devices like Redmi,Asus,Micromax.But it is not showing in Samsung phones,it's not going to file manager
How to get FileManager in Samsung phones to select a file?

try this is working for me
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(intent , CHOOSE_FILE_REQUESTCODE);
for Samsung Devices
String manufactures = android.os.Build.MANUFACTURER;
if(manufactures.equalsIgnoreCase("samsung")){
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);
}

Replace
Intent intent = new Intent(Intent.ACTION_VIEW);
as
Intent intent = new Intent(Intent.GET_CONTENT);
EDIT
#Hanuman i think that single solution that fits all models doesn't exist, all intents with "actions" have to be processed by choosers. If you use >= 4.4 devices, I recommend
Storage Access Framework

Facebook Link doesnt work android

Hello I just want to call Facebook app with the link below (on my android project):
String url_facebook_prixo = "https://www.facebook.com/pages/Prixo/468580313168290";
I tried this :
Uri uri = Uri.parse("facebook://facebook.com/page{468580313168290}");
Intent viewIntent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(viewIntent);
I tried with others link but its only displaying my wall..
Someone?

You should use the id to open the page.
Intent facebookIntent = new Intent(
Intent.ACTION_VIEW,
Uri.parse("fb://profile/468580313168290"));
startActivity(facebookIntent);
I would advice you to encapsulate this in a try catch. Inside the catch open a normal browser intent

How to fire up the stock Gallery app with an image url that's in sd card

I have an image on the sd card. I need to fire up the stock Gallery app from my app to show the image. I get a NullPointerException from the stock Gallery app.
Here is my code.
Intent i = new Intent(Intent.ACTION_VIEW);
i.setType("image/png");
i.putExtra(Intent.EXTRA_STREAM, Uri.parse(IMAGE_URL_ON_SD_CARD));
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
Can anyone help me understand what I am doing wrong?
Thanks a lot.

Try like this..
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("content://media/external/images/media/16")));
If above code do not work thn try like this
Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse("file://" + "/sdcard/test.jpg"), "image/*"); startActivity(intent);

startActivity on "file://" links crashes

I am trying to create program that simply opens file on sdcard. I tried opening mp3, mp4, and apk - the code bellow always crashes unexpectedly.
String _path = "file:///sdcard/1.apk";
Uri outputFileUri = Uri.parse(_path);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Market links also crashes. But when I set _path="http://google.com" - browser opens normally. How can I make this code work?

If you're trying to install the apk, you need to use the following:
String fileName = Environment.getExternalStorageDirectory() + "/1.apk";
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive");
startActivity(intent);
If you're trying to launch the app (after installing), then:
Intent intent = new Intent();
intent.setClassName("com.pkg.addr", "com.pkg.addr.MainActivity");
startActivity(intent);
If you're trying to launch a player to play the mp3 file:
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
Uri data = Uri.parse("file:///sdcard/1.mp3");
intent.setDataAndType(data,"audio/mp3");
startActivity(intent);
Hope that helps.
