This SDK enables you to support previewing Box files within your application.
Types of files supported:
- images
- PDFs
- audio/video files
- markdown/text/code files
- Office documents
Currently not supported:
- Box Notes
The box preview sdk is currently private, and distributed as an aar file through maven:
compile 'com.box:box-android-preview-sdk:1.0.0'Please refer to the build.gradle file in box-preview-sample for setting up your gradle dependencies.
Refer to box-content-sdk for details on how to set your client id, and secret; and authenticate the user.
You can get a BoxFile instance using the box-content-sdk or the box-browse-sdk
The simplest way to preview a single file, is to start a BoxPreviewActivity, the intent for which can be created using the createIntentBuilder factory method.
BoxPreviewActivity.IntentBuilder builder = BoxPreviewActivity.createIntentBuilder(this, boxSession, boxFile);
####Paging through multiple images, audio or video files Passing the BoxFolder to the intent builder BoxPreviewActivity allows the sdk to also load other files of the same type from the parent folder into a custom ViewPager called the BoxPreviewViewPager. Another way of doing this, is to directly pass a BoxItems collection to the builder.
builder.setBoxFolder(boxFolder);
// or
// builder.setBoxItems(boxItems);
Precaching files:
To preload files into the cache, without presenting them, make use of com.box.androidsdk.preview.BoxPreviewViewPager.getCacheFileRequest api.
FutureTask task = BoxPreviewViewPager.getCacheFileRequest(boxSession, previewStorage, boxFile);
Customizing cache policy:
You can customize the max cache size (default 500MB), and cache age (default 90 days) by defininig
com.box.androidsdk.preview.PreviewStorage.MAX_CACHE_SIZE com.box.androidsdk.preview.PreviewStorage.MAX_CACHE_AGE
Cache age defines how long an unaccessed file will stay in the cache, if it hasn't been cleared out of the LRU cache for memory.
A sample app can be found in the box-preview-sample folder.
