What is getSeekableFileDescriptor() in this android doc?


Some of Google's code snippets use placeholders for methods providing data required by the sample.

In this case, getSeekableFileDescriptor() needs to return a ParcelFileDescriptor that PdfRenderer can use. In particular, it needs to be "seekable", meaning that a stream opened on the ParcelFileDescriptor needs to be one that can be seeked forwards and backwards. For example, the static open() method on ParcelFileDescriptor gives you a seekable descriptor; createPipe() does not.

Creating standalone android library project using Android Studio (0.8.14)
There are a couple of ways I've tried doing this, a quick and easy way to do this is to symlink your library module directory to a directory in your project and add it to your settings.gradle. A better way to do it is to import the library module as a VCS project (local git works fine) It will still clone the library module into each project but changes made to the library will be consistent acros

Why would Android Studio 1.0 rc start downloading Android SDK without detecting if there existing one?
Looks like that is in the known issues list: http://tools.android.com/knownissues A bug in Android Studio 1.0 RC1 causes the Setup Wizard to show up and ask you to install an SDK on each startup. To work around this, you can edit the idea.properties file in the bin folder such that it has the below line as well: disable.android.first.run=true PLEASE NOTE: This will break patch updating
