2020-03-08usb-serial-for-android: Implement timeout-handlingGravatar Christof Arnosti
Since the Android USB stack and subsequently the usb-serial-for-android driver have problems with read-timeouts, the read-timeout is now implemented in AndroidSerial.java. Also, DC_STATUS_TIMEOUT is returned if there are less bytes returned than expected. Different chipsets seem to behave differently with usb-serial-for-android. On CP210x the read blocks until there is some data here, but on FTDI the chip seems to return whatever is currently in the buffer (so 0 bytes if the buffer is empty). This different behaviour should be mitigated by the changes by this commit. Signed-off-by: Christof Arnosti <charno@charno.ch>

Implement the libdivecomputer API in Java and create C/JNI translation layer. [Dirk Hohndel: whitespace harmonization - yes, some of this is Java, this still makes it much easier to read for me; also changed the FTDI conditional compilation to make sure we can still use that for mobile-on-desktop if necessary] Signed-off-by: Christof Arnosti <charno@charno.ch> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2018-08-11Android: only handle Intents after the app is initializedGravatar Dirk Hohndel
The old code happened to work because this function only got called if the app was already running, but the correct thing to do is to always wait until we have first called back from C++ code, indicating that the app is indeed fully initialized. This way we only process the Intent in one place in the Java code. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2018-08-11Android: add callback from IntentGravatar Dirk Hohndel
Right now all this does is add the device string to the log. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2018-08-11Android: add Java class to receive IntentsGravatar Dirk Hohndel
We want to be able to respond to a USB device being plugged in. This simply logs the information we get from the device. Sadly the really useful getProductName and getManufacturerName require API level 21 (so Android 5.0 or newer) and we still have a couple hundred users on 4.1-4.4.
