4UMaps are some of the nicer OpenStreetMap-based maps, maintained and served independently of OSM (and MyTrails).
They have recently updated their server, and some versions of Android seem to have trouble connecting to the new server. You can fix this by changing the map definition for 4Umaps to use the following URL:
{2}/{0}/{1}.png
Alternatively, just tap this link from your Android device to import a new map definition with this URL.
Update: the 4Umaps URL changed again. And again…
To connect MyTrails to your Google account so you can share subscriptions between devices, just open the side navigation menu and tap the Connect button.
Tap the icon in the top-left of the screen to open this menu
In the screen that opens, tap Connect again, choose one of your Google accounts (always the same!) if you have more than one and go through the authorization.
Tap connect, then accept the authorization prompts
In the side navigation menu, the Connect button will be replaced with the email address of your account.
Sometimes, MyTrails needs to refresh the association with your Google account. In that case, open the side navigation menu, tap the email address, and in the next screen, Disconnect, then Connect again.
Tap Disconnect, then Connect again
In order to calculate the cumulated altitude differential, MyTrails must identify parts of the altitude curve where the track switches from uphill to downhill or vice versa. Because altitude measurements are not exact (especially from the GPS), MyTrails uses a filter to attempt to differentiate measurement errors from actual changes in the track.
Different applications use different filters, which may yield very different altitude differentials.
You will get better results when using altimeter-derived altitudes, or after applying altitude normalization (when saving the track, or in the Track Manager).
In MyTrails 2.0.11 and later, you can additionally use two options in Preferences > Sensors: Altitude stabilization (which performs some filtering on GPS altitude data to reduce the noise) and Cumulative climb filter, which you can set higher to avoid MyTrails overestimating cumulative climb when the GPS data is very noisy.
Google is retiring Wallet for digital purchases on March 1st, so for map purchases on my site, I am migrating to PayPal.
You can pay with your PayPal balance or a credit card, and the prices are the same as with Wallet.
Until Wallet is actually shut down, you will be able to use either payment solution.
MyTrails 2.0.9 introduces a new recording UI, which should make it easier for new users to grasp what the application is doing. The original recording UI is still available and will continue to be supported for users who prefer a greater degree of control.
You can select the type of recording UI in MyTrails > Preferences > Recording, Extended recording UI (uncheck for the new UI).
The new system consists of two buttons: Record/Pause and Stop.
Currently recording
The icon that is lit corresponds to the current recording state. Tap a button to switch to that state. For example, to pause the recording (without saving and closing the track), tap Record/Pause.
Tap the Stop button when you are done with your recording: MyTrails asks you to save the track (providing a name, etc.), and possibly upload the track to a community. The recording is then cleared, so MyTrails is ready for another recording, which you can do immediately by hitting the Record button.
You can also find the recording controls in the navigation menu, which is available on all main screens (stats, graphs, tracks, maps, etc.), not just the map view.
With this new mode, MyTrails tries to make it very quick and easy to record your tracks:
So you’ve downloaded a bunch of maps offline, and MyTrails placed them on your phone’s internal storage?
MyTrails doesn’t attempt to help do this, because moving large amounts of data around is difficult to do in a compatible and safe way. So please follow this guide:
/sdcard/MyTrails/Offline to the location you selected above
If step 3 sounds too tedious, you can skip it; the next time MyTrails starts (you can stop it manually to make this happen sooner), it will automatically regenerate the map definitions for you (but it leaves the old ones, you’ll need to hide them in MyTrails > Maps, or delete them by long-pressing the map names and selecting Delete – make sure not to delete the map data, just the definition!).
If this does not succeed, please use the reset offline hidden option.
