1207252 - Investigate: Do NS_XPCOM_CURRENT_PROCESS_DIR and Context.getApplicationInfo().dataDir always point to the same writable path?

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[Sebastian Kaspari (:sebastian; :pocmo)]

In bug 1197717 we added support for loading fonts from NS_XPCOM_CURRENT_PROCESS_DIR/fonts to later download fonts to that directory from Java. But there are some open questions that need further investigation and testing:

* Do NS_XPCOM_CURRENT_PROCESS_DIR and Context.getApplicationInfo().dataDir always point to the same direction? -> How does nsDirectoryService resolve that constant to the actual path (on Android)?

* Can it happen that this directory is readable-only?

* Are we facing any problems if the app is installed in /systems/app?

Note: nsHyphenationManager is loading hyphenation dictionaries from NS_XPCOM_CURRENT_PROCESS_DIR/hyphenation:
