emulation

问题 I tried to debug my Android app on Chrome OS emulator in Android studio. This is the tutorial I followed: https://developer.android.com/topic/arc/emulator The problem is, it crashes on startup. If I try to launch it via terminal, I get this output: ./emulator -avd Pixelbook_beta_API_25 emulator: WARNING: encryption is off emulator: WARNING: Running on a system with less than 6 logical cores. Setting number of virtual cores to 1 qemu-system-x86_64: -usbdevice tablet: '-usbdevice' is deprecated

问题 Is there any way to develop NFC tag reading/writing applications without an NFC enabled phone? Is there a way to create an AVD which has NFC enabled? I have searched and found Open NFC exists, but I cannot find much information about it now. Is it already obsolete? Is there any other way to achieve it? 回答1: Google never implemented support for NFC in the AVD. So there is no official support for NFC in the Android device emulator. Back in the early days of NFC on Android, Inside Secure

问题 I'm trying to restore a backup of my datastore entities into the emulator running on localhost. I'm using the guide from this location https://cloud.google.com/datastore/docs/tools/emulator-export-import This is what I have managed to do so far. #start the emulator gcloud beta emulators datastore start --store-on-disk --data-dir "./datastore-emulator" --project=my-project # set the environment $(gcloud beta emulators datastore env-init) # initiate the restore operation curl -X POST localhost

问题 I'm trying to mount the userdata-qemu.img.qcow2 file created by the Android emulator. The following procedure does not work: sudo qemu-nbd -c /dev/nbd0 ~/.android/avd/Pixel_C_API_27.avd/userdata-qemu.img.qcow2 First command runs well, but running sudo qemu-nbd -c /dev/nbd0 ~/.android/avd/Pixel_C_API_27.avd/userdata-qemu.img.qcow2 results in this output: Fehler: /dev/nbd0: unbekannte Partitionstabelle Modell: Unbekannt (unknown) Festplatte /dev/nbd0: 3146MB Sektorgröße (logisch/physisch): 512B

问题 I checked the original site of the internet archive and they mentioned there a couple of steps to follow, which included the use of the wget utility using Cygwin over windows, I followed the steps above, I made an advanced search and extracted the CSV file, converted it to .txt and then tried to run the following commands wget -r -H -nc -np -nH --cut-dirs=1 -A .pdf,.epub -e robots=off -l1 -i ./itemlist.txt -B 'http://archive.org/download/ The emulator gets stuck afterwards and no log message
