2020-03-16usb-serial-for-android: Use wakelockGravatar Christof Arnosti
Android takes some pretty hard measures to save power, including shutting down the CPU. Since this can interfer with the download from an usb serial device, we now use a wakelock to keep the CPU running during download.

2020-03-16android usb serial: Prepare device / driver selectGravatar Christof Arnosti
This commit contains the serial_android_usb part of the changes proposed in issue #2657. What's implemented: - A data structure that contains all the data that can be used to describe an usb device (including user-facing string). - A function to get a list of all attached usb devices (optionally with selectable driver class). - Changes in the serial_android_usb_open-function and in the Java part to use the information about the usb device and optionally selected driver when connecting. This commit keeps compatibility with the current UI-Code in the case that only one USB-Device is connected. If two devices are connected, only the first one is tried. There are still some small things to do: - Change the user-facing string to something more descriptive. - Parts which aren't uesd anymore when the UI-Part is implemented are simply marked as obsolete (to keep compatibility for now). But generally it seems to work. [Dirk Hohndel: some white space / coding style adjustments] Signed-off-by: Christof Arnosti <charno@charno.ch> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
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>

2020-03-07usb-serial-for-android: ImplementationGravatar Christof Arnosti
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>
