android/usb: simply restart the download after receiving permission

2020-03-16T14:58:20Z

If the user tries to download from a device that he hasn't given the app permission to read from, Android will pop up a dialogue asking for that permission. With this after giving the permission we continue (well, technically, restart) the download which is likely the expected behavior. Signed-off-by: Dirk Hohndel

android/usb: show download page again after USB permission granted

2020-03-16T14:58:20Z

If the user hadn't granted USB permissions, yet, we asynchronously get informed once they did that. This ensures that the user gets taken back to the download page once they approve. Signed-off-by: Dirk Hohndel

android/usb: pass the usbDevice for intent handling

2020-03-16T14:58:20Z

Instead of creating a string with all the object information, simply pass the actual object to the C++ code. Signed-off-by: Dirk Hohndel

usb-serial-for-android: React to usb "permit granted" intent (stub)

2020-03-16T14:58:20Z

When a user is downloading from a DC for the first time (without using the "usb device connected" popup), the user is requested to grant permission to use the USB device. This is done asynchronously, thus the download is aborted. To be more user-friendly, we now react to the intent with the "usb granted" result. The plan here is to start the download again.

usb-serial-for-android: Use wakelock

2020-03-16T14:58:20Z

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. Signed-off-by: Christof Arnosti Signed-off-by: Dirk Hohndel

android usb serial: Prepare device / driver select

2020-03-16T14:58:20Z

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 Signed-off-by: Dirk Hohndel

Android: remove USB devices we don't support

2020-03-10T20:27:43Z

The HID devices and the Atomics Aquatics Cobalt cannot work on Android right now. We should claim to support them. Signed-off-by: Dirk Hohndel

usb-serial-for-android: Implement timeout-handling

2020-03-08T18:22:55Z

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
