Android on emulator loads infinitely

[MichaelRocks]

I wanted to try nanoscope on emulator, installed it from Homebrew, launched the emulator with nanoscope emulator but the emulator never finished launching. Unfortunately, I don't know what information I need to provide so you can reproduce this issue. But I'm ready to try it again and send you some logs.

[Leland-Takamine]

I've had one other report of this internally. Can you paste both the output of the terminal command and the logcat output (if any)?

[MichaelRocks]

Seems Android compiles some classes but does it very slowly. I'll try to wait for 12 hours or so. Maybe it'll finish.
logcat.log
output.log

[Leland-Takamine]

Looks like it's due to HAXM not loading:

HAXM is not working and emulator runs in emulation mode

This will cause the emulator to run much slower. Do you have HAXM installed?

[MichaelRocks]

Yes, I have it installed and emulators from Android SDK work just fine. I waited for a little longer and it seems Android entered some kind of a boot-loop.
logcat.log

[Leland-Takamine]

Ok, I'll try to take a look at this more but it may not be for a couple weeks since I'm on vacation. My guess is that this is due to HAXM not loading, so if you can solve that then it may fix the issue. Found this after a brief search - hopefully helpful.

[MichaelRocks]

Seems I managed to load the emulator with HAXM support by manually loading HAXM kext with sudo kextload -b com.intel.kext.intelhaxm. I ran this command, then allowed loading the extension in System Preferences -> Security & Privacy, and then ran the same command again. Now nanoscope emulator prints the following lines:

emulator: CPU Acceleration: working
emulator: CPU Acceleration status: HAXM version 7.1.0 (4) is installed and usable.

Add the emulator even managed to load Android but it took quite a long time comparing to default emulators from Android SDK.

[CheerS17]

I encounter the same problem, also installed HAXM from Android Studio and manually, but neither work.

[CheerS17]

Finally solve this problem, I tried those steps one by one, but I don't know which one really works.

1. kill all adb service, then restart, try again.
2. Restart Mac, try again.
3. Uninstall HAXM, then re-install, set the RAM to recommended size(2GB for me), restart Mac, try again.

The booting of emulator takes several minutes (5-10 mins for me).

[Leland-Takamine]

The booting of emulator takes several minutes (5-10 mins for me).

@CheerS17 That seems like a long time for a HAXM emulator. Are you sure HAXM successfully loads? Mind pasting the logs from the nanoscope emulator command here?

[CheerS17]

I think so, I can see this log: emulator:

Adding boot property: 'ro.opengles.version' = '131072' HAXM is working and emulator runs in fast virt mode.

here are all outputs after typing nanoscope emulator.

I am also facing the same issue . Is this issue fixed?

@warabei14 Trying to reinstall the HXAM, the first time it may take a long time to load the emulator, but it will be faster for the following loadings.

[ashishb]

Looking at emulator: Warning: config.ini contains invalid skin.path entry: (null), try with -no-skin. That might fix the issue.

[Tagakov]

In addition to @ashishb reply. Try to remove

-skindir $ANDROID_HOME/skins \
-skin pixel

From ~/.nanoscope/roms/<UID>/emulator.sh

This issue in the Google bug tracker might be helpful.

[Leland-Takamine]

The latest version of Nanoscope creates a proper AVD with the nanoscope emulator command. Please update to the latest version brew upgrade nanoscope and re-open if this doesn't fix your issue.
