Display image intent rebuilds cache - android

When I create an intent and pass it a URI of the path of the image on the SD card, like this:
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
The image displays after about 15 seconds, because the image viewer has to rebuild its image cache. It says in the debugger
Unable to read the index file sdcard/Android/data/com.cooliris.media/cache/picasa-thumbsindex.
I'm 99% sure this is a permissions issue, it cannot access its cache file. How do I fix this?

How to open default gallery app with particular album or folder?

Every example i found on net is opening gallery and get images from gallery as result. My need is i don't want result or images to my app. I just want to trigger gallery app with showing particular folder of images. My App Have separate folder to save images. i need to navigate users directly to that path.
Try this code. It will retrieve view pictures under storage/emulated/0/Pictures/AppPics You can change the file path according to your directory path.
File sdDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File file = new File(sdDir, "AppPics");
if (file.isDirectory())
listFile = file.listFiles();
EDIT: To open your folder using intent
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.withAppendedPath(Uri.fromFile(file), "/AppPics"), "image/*");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
You can try like this,
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = [Uri for your folder];
intent.setDataAndType(uri, "image/*");
startActivity(Intent.createChooser(intent, "Open [App] images"));

How to create an intent to open .doc file using Polaris Viewer on Android?

I am trying to open a .doc file from my SD card using Polaris Viewer.
I keep on getting a message saying "This document cannot be opened".
weird thing is that I CAN open it from elsewhere.
I have ES File Explorer on my phone and I can open through there. It does it via Polaris Viewer so the file is obviously okay.
The only thing I can think of is that I have a problem with my intent.
Is there any way to see exactly what intent ES File Explorer sent?
This is my code (textOpenUri is a full path name of the file to be opened):
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(textOpenUri, "application/msword");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
I did a small test (just to make sure it is not defaulting to some other app) using:
List<ResolveInfo> list = getActivity().getPackageManager().queryIntentActivities(intent,0);
and I get back Polaris as the only app that can deal with the intent.
Intent intent = new Intent("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.addFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
Uri uri = Uri.fromFile(file);
intent.setDataAndType(uri, "application/msword");
this.startActivity(intent);
startActivity(intent);

Displaying a specific folder of photos in the Android Gallery App

I'm looking to display a specific folder of images in an app so that the user can browse through them.
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("content://sdcard/Pictures/Album"), "image/*");
startActivityForResult(intent, 0);
This seems to display all photos on the phone instead of the images I have in this album. How can I change this code so that the user can browse through images in a specific folder using the gallery app? The idea behind this is not so that the user can choose an image like I've seen in many examples on here but just simply to browse the images.
you can try this
File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
Uri uri = Uri.fromFile(root);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
startActivityForResult(intent, 1);

Intent for image display

I've a sequence of image paths on my sd card and I display them on a list.
I'd like to associate the onitemclick to image visualization and, rather than create my own activity, I wanted to know if there was an intent which, given an image path, displays it.
This solution assumes that you have the path of your image:
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);

Android How to preview an image, using its file path from SDcard, from my application

File is present in sdcard/image.jpg
I would like to create my own application (activity).
On a button press, the image stored in the sdcard needs to be displayed using the built-in image viewer.
On pressing the back button from the Image viewer, it should go back to my running application.
Need some help.
you can create an Intent with proper uri and mimetype for this.Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.parse("file:///sdcard/image.jpg"), "image/jpeg");
startActivity(i);
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
This code use for display all images from your SD card
