Android open gallery from folder

I want to show a photo in android gallery, and be able to slide throw the others photos on that folder.
Intent intent = new Intent(Intent.ACTION_VIEW);
File f = new File(path);
intent.setDataAndType(Uri.parse("file://" + f.getAbsolutePath()), "image/*");
mContext.startActivity(intent);
thats how i am doing it now, but wont let me slide throw the rest of the images in the folder.
i tried:
How to open one particular folder from gallery in android?
Built-in gallery in specific folder
Gallery with folder filter
Without any luck.
i would be really happy if someone have the solution.
Thanks!

Try This
Intent i=new Intent();
i.setAction(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(new File(path)), "image/*");
startActivity(i);

This question is from five years ago, However I want to give an answer that worked for me instead of the correct answer.
In order to show the photo and slide through the others photos, we need to give to the intent not the file uri but the media uri.
public void ShowPhoto(File imageFile) {
String mediaId = "";
String[] projection = new String[] {
MediaStore.Images.Media._ID,
MediaStore.Images.Media.DISPLAY_NAME
};
Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, null, null, null);
while (cursor != null && cursor.moveToNext()) {
String name = cursor.getString((cursor.getColumnIndex(MediaStore.Images.ImageColumns.DISPLAY_NAME)));
if(name.equals(imageFile.getName())){
mediaId = cursor.getString((cursor.getColumnIndex(MediaStore.Images.ImageColumns._ID)));
break;
}
}
Uri mediaUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
if(!mediaId.equals("")){
mediaUri = mediaUri.buildUpon()
.authority("media")
.appendPath(mediaId)
.build();
}
Log.d("TagInfo","Uri: "+mediaUri);
Intent intent = new Intent(Intent.ACTION_VIEW, mediaUri);
startActivity(intent);
}

Try this way,hope this will help you to solve your problem.
final int OPEN_GALLERY = 1
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), OPEN_GALLERY);

Save image from custom camera in specific URI

I am receive an URI from my Activity. I want to be able to save a picture from my Custom Camera into that specific location, I don't know how to achieve that. Can I get some help?
I see how to save an image from the Google developer website but they create a folder, name the picture with date and etc. I have an URI which contains all the information. All I need to do is to save a picture in that URI.
Initially, I am trying to achieve manually what the camera intent does when you add this extra:
intent.putExtra(MediaStore.EXTRA_OUTPUT, URI_GOES_HERE);
Here is the code in the current Activity where the URI is passed to my Custom Camera as an Extra:
String filename = System.currentTimeMillis() + ".jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, filename);
preDefinedCameraUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values);
Log.d("Predefined URI:","" + preDefinedCameraUri);
intent.putExtra(MediaStore.EXTRA_OUTPUT, preDefinedCameraUri);
How do I save the picture in that extra?

How to create camera button that stores images to gallery?

How would I correctly get a buttons intent to take a picture and store that image in the phones gallery? So far i have a button which is in a case structure that says :
else if (v.getId() == R.id.button5)//camera
{
Intent c = new Intent( MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(c,1);
}
what should my onActivityResult look like since i am just storing that image to the gallery?
would i have to use something as bundle extras = data.getExtras();?

This answer may be your problems solution. But data.getExtras() returns null in some cases and unfortunately I have not detected all of these cases yet. For example data.getExtras() worked fine on android 2.3 HTC Evo 3D but on android 2.3 Samsung Galaxy SII, it returned null. Hope this helps.

First, you have to call your startActivityForResult() method like the following:
Uri imageFileUri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, new ContentValues());
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageFileUri);
startActivityForResult(i, CAMERA_RESULT);
And in the implementation of startActivityForResult() method you have to write the following:
// Save the name and description of an image in a ContentValues map.
ContentValues contentValues = new ContentValues(3);
contentValues.put(Media.DISPLAY_NAME, "This is a test title");
contentValues.put(Media.DESCRIPTION, "This is a test description");
contentValues.put(Media.MIME_TYPE, "image/jpeg");
// Add a new record without the bitmap, but with some values set.
// insert() returns the URI of the new record.
Uri imageFileUri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,contentValues);

Browse path on SD card via Intent

I'd like to know if there's a way to open a file browser (system or 3rd party like Astro) to a specific path. There's not much else to say here... pretty straight-forward question.

Sounds like ACTION_GET_CONTENT is what you want. See here. The relevant bits would be:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent,PICKFILE_RESULT_CODE);
On my phone (which has astro already installed), this brings up an astro dialog for /sdcard. I'm not sure what this will do on a phone with no file browser installed. I'm also unsure about whether you are able to actually specify the starting path using this method. The docs make it sound like you can't specify a starting uri for ACTION_GET_CONTENT.
EDIT: I think I understand the question better now. I thought you were wanting a picker style browser to just get a file path from the user. If you want a full blown browser to handle your uri, then this worked for me:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file:///mnt/sdcard/Music"), "*/*");
startActivity(intent);
That will probably give you quite a long list of possible handlers, but I'd bet any file manager on the system would be in the list (astro certainly is).

I don't believe that any of the manufacturer provided File Browsers provide such a thing.
Though I don't see anything glaringly wrong with the theory of doing so. I imagine you are more likely to find a 3rd party file browser with this feature, but I've never come across any of those either.
You might look in to the Open Intents OI File Manager this concept seems right up their ally, if they don't already have this feature, I bet they might consider adding it if you get in contact with them.

Here i am going to show you that how to create a BROWSE button, which when you will click, it will open up the SDCARD, you will select a File and in result you will get the File Name and File path of the selected one:
// A button which you will hit**
browse.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
Uri startDir = Uri.fromFile(new File("/sdcard"));
startActivityForResult(intent, PICK_REQUEST_CODE);
}
});
//The function which will get the Resulted File Name and File Path
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == PICK_REQUEST_CODE)
{
if (resultCode == RESULT_OK)
{
Uri uri = intent.getData();
if (uri.getScheme().toString().compareTo("content")==0)
{
Cursor cursor =getContentResolver().query(uri, null, null, null, null);
if (cursor.moveToFirst())
{
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
Uri filePathUri = Uri.parse(cursor.getString(column_index));
String file_name = filePathUri.getLastPathSegment().toString();
String file_path=filePathUri.getPath();
Toast.makeText(this,"File Name & PATH are:"+file_name+"\n"+file_path, Toast.LENGTH_LONG).show();
}
}
}
}
}

Jpeg compression quality in android

I am launching the image capture intent to take a picture, adding a uri so the picture is tiny. My problem is I want to set the output jpeg-quality before I start the activity.
ContentValues vals = new ContentValues();
vals.put(Media.DISPLAY_NAME, "test title");
vals.put(Media.MIME_TYPE, "image/jpeg");
Uri imageFileUri = context.getContentResolver()
.insert(Media.EXTERNAL_CONTENT_URI, vals);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageFileUri);
context.startActivityForResult(i, CameraImportActivity.CAMERA_REQUEST);
I suppose I could downsample after the picture is taken, but if I can request the activity do it for me I would like to do so.
As bonus questions, how do I change the album they get saved to in the gallery, and how do I prevent the camera activity from saving a copy in the default location (on my phone it is "photos")
