The GitHub repo is still the source of truth and this is a read-only vendor. This should let us experiment more incrementally with the monorepo. Differential Revision: https://phabricator.services.mozilla.com/D282538

## Application Services Logging
|
|
|
|
When writing code in application-services, code implemented in Rust, Kotlin,
|
|
Java, or Swift might have to write debug logs. To do so, one should generally
|
|
log using the normal logging facilities for the language. Where the logs go
|
|
depends on the application which is embedding the components.
|
|
|
|
### Accessing logs when running Firefox Android
|
|
|
|
On android, logs currently go to logcat. (This may change in the future.)
|
|
Android Studio can be used to view the logcat logs; connect the device over USB
|
|
and view the Logcat tab at the bottom of Android Studio. Check to make sure you
|
|
have the right device selected at the top left of the Logcat pane, and the
|
|
correct process to the right of that. One trick to avoid having to select the
|
|
correct process (as there are main and content processes) is to choose "No
|
|
Filters" from the menu on the top right of the Logcat pane. Then, use the search
|
|
box to search for the log messages you are trying to find.
|
|
|
|
There are also many other utilities, command line and graphical, that can be
|
|
used to view logcat logs from a connected android device in a more flexible
|
|
manner.
|
|
|
|
#### Changing the loglevel in Firefox Android
|
|
|
|
If you need more verbose logging, after the call to `RustLog.enable()` in
|
|
`FenixApplication`, you may call `RustLog.setMaxLevel(Log.Priority.DEBUG,
|
|
true)`.
|
|
|
|
### Accessing logs when running Firefox iOS
|
|
|
|
If you're using `Xcode`, then you can view the logs in the debugger.
|
|
|
|
If you're not using `Xcode`, then:
|
|
|
|
* Navigate to the settings page
|
|
* tap the version number 5 times to get to the secret menu
|
|
* Select "copy log files to container"
|
|
* Find the logs on your files folder
|
|
|
|
