Oh My SAF

Android SAF helper.

Implement

1. Add maven.yuuta.dev repo to your module

2. Add dependency:

implementation 'moe.yuuta.ohmysaf:ohmysaf:<the latest version>'

Main Features

• Faster migrate - If you have an old project which uses java.io.File a lot and you would like to migrate to SAF, OMG. By using OhMySAF, you can just continue using File with a little hack.

Faster Migrate

Imagine that you have an old project and its file operation codes look like:

File theFxxkFile = new File("xxx/xxx");
if (theFxxkFile.isFile()) {
    theFxxkFile.delete();
    theFxxkFile.mkdir(); // In fact, SAF does not support that.
}

If you want to switch to SAF, the normal code will look like:

// Assume that you've got the URI
DocumentFile theFxxkFile = DocumentFile.fromTreeUri(context, uri);
if (theFxxkFile.isFile()) {
    theFxxkFile.delete();
    // .....
}

One day you discovered OhMySAF, your problem is solved:

// Assume that you've got the URI

// Magic
File theFxxkFile = OhMySAF.ohMyTree(context, uri);

// Just KEEP these old codes!
if (theFxxkFile.isFile()) {
    theFxxkFile.delete();
    theFxxkFile.mkdir(); // In fact, SAF does not support that.
}

Extend usages

Some APIs don't work with SafFile. In these cases, you should cast the returned File to SafFile and use extended APIs.

SafFile theMagic = OhMySAF.ohMyUri(context, uri);

Get Android Uri

It returns the Android Uri and you can do ANYTHING you want with it.

final Uri uri = theMagic.getAndroidUri();

Open input / output stream

The Java FileInputStream and FileOutputStream does not work with the file directly. Talk is cheap, let's show you the code:

final OutputStream stream = theMagic.openOutputStream(this, "w");
stream.close();
