- Extend NSBundle resources support to handle directories in Android assets.
- Fix NSFileManager -isReadableFileAtPath: to also support directories in Android assets.
Requires passing the activity's AssetManager object from Java to GNUstep by calling +[NSBundle setJavaAssetManager:withJNIEnv:], which then enables the following features:
- NSBundle main bundle resource paths support for Android assets, e.g. for pathForResource:ofType:, URLForResource:ofType: and related methods.
- NSBundle main bundle info dictionary support if Info.plist exists in Android assets.
- -initWithContentsOfFile: and related methods support for reading Android assets from main bundle in various classes (e.g. NSData, NSDictionary, NSArray, etc.).
- NSFileManager fileExistsAtPath:(isDirectory:) and isReadableFileAtPath: return YES for main bundle asset / asset directory paths.
- NSFileHandle support for reading Android assets from main bundle.
- NSDirectoryEnumerator support for enumerating Android assets from main bundle. Note that recursion into subdirectories is currently not supported by the native Android asset manager API (see https://issuetracker.google.com/issues/37002833).
Also adds support for automatic NSProcessInfo initialization on Android with a fake executable path "/data/data/<app identifier>/exe" (as Android apps don't have a real executable path), and tweaks main bundle initialization to allow that path. Main bundle resource paths are prefixed by "/data/data/<app identifier>/Resources".
Implement a method for getting attribytes of a file system path. Reuse
the implementation of -fileSystemAttributesAtPath: for this purpose but
export the last system errors to the caller. Make
-fileSystemAttributesAtPath: use the new implementation, without
exposing error info to the caller.
Create NSFileManagerDelegate, a more modern manner to verify whether to
proceed a file operation after an error or whether an operation should
actually be performed by NSFileManager.
No functionality using the delegate is yet implemented.
a few testcases ...
The basic method should fail if the directory already exists.
The intermediate directories method should fail if the directory exists unless
the option to create intermediate directories is selected, in which case a
pre-existing directory is counted as a success.
