Emulated Android device does not re-sync time/date after restoring snapshot

阅读更多关于 Emulated Android device does not re-sync time/date after restoring snapshot

问题 If I do a fresh boot on the emulated device, it gets the correct current time from the host OS; however, if I reload the device from a snapshot, it gets the time/date from the moment the snapshot was created (e.g. When I shut down the emulator). The time/date does not re-sync after any amount of time. The only way around it that I've found is to manually update the time after restoring from a snapshot. The Android Virtual Device has default properties: Target = Android 4.0.3 - API Level 15

I've been trying to send message on Android 4.0 emulator via Broadcasting and fetch that message via Broadcast receiver. I'm able to do so with two emulators, say, from 5554 to 5556.

Need help correctly emulating the Samsung Galaxy Nexus with AVD

阅读更多关于 Need help correctly emulating the Samsung Galaxy Nexus with AVD

I'm working to ensure my app is getting tested on ICS properly using the popular Galaxy Nexus as a basis. I'd like to emulate it as faithfully as possible. I've created an AVD with the following parameters (from config.ini). This was mostly created using the GUI (disk.dataPartition.size is a hand-edited param based on other articles I've read). The memory values may be on the low side but that's not causing a problem for me at the moment. Since the device had no external sdcard I've said "no" for hw.sdCard, but I'm clearly not seeing anything in the /mnt/scdcard (same as /sdcard) and cannot

阅读更多关于 Possible to run WebGL content from an android emulator?

问题 Hello I have been trying to run WebGL content in a number of android emulators( BlueStacks, Andy, Duos, and VirtualBox ). When I try to access any WebGL content in a browser( chrome, firefox ) I get a message stating that WebGL is not supported by my video card. Of course WebGL works fine outside of the emulator.
