如何解决启动Nexus_4_API_27模拟器时的快照超时错误？

Hey there, I’ve dealt with this exact snapshot pending error on Android emulators plenty of times—it’s such a headache when you’re trying to test something quickly. Let’s go through the proven fixes that get the emulator up and running again:

1. Delete the Stuck Snapshot Files Directly #

The root cause is almost always a locked or corrupted snapshot file. Here’s how to nuke it:

• Head to your AVD’s storage directory. On Linux, this is typically ~/.android/avd/Nexus_4_API_27.avd/
• Look for files named snapshot.lock or any files ending with .snapshot that seem out of place
• Delete these files (you might need to use sudo if you hit permission issues)
• Try launching your emulator again with your original command: ./emulator -avd Nexus_4_API_27

2. Kill All Leftover Emulator Processes #

Sometimes background emulator daemons hang onto the snapshot lock. Let’s clean them up:

• First, stop the ADB server with: adb kill-server
• Next, find all running emulator-related processes: ps aux | grep emulator
• Kill each process with: kill -9 <process-id> (replace <process-id> with the number from the previous command’s output)
• Restart the emulator after this cleanup

3. Disable Snapshots for the AVD #

If snapshots keep causing trouble, you can turn them off entirely (temporarily or permanently):

• Open Android Studio’s AVD Manager
• Find your Nexus_4_API_27 emulator, click the pencil icon to edit it
• Scroll down to Show Advanced Settings
• Under the Snapshot Options section, uncheck Enable snapshots
• Save your changes and launch the emulator again

4. Wipe the Emulator’s Data #

Corrupted app data or system cache can also trigger this timeout error:

• In AVD Manager, select your emulator and click the Wipe Data button
• Confirm the action, then try starting the emulator once more

5. Check Your Disk Space #

Don’t overlook this simple fix—low disk space can make snapshot operations fail silently. Ensure you have at least 10GB of free space on the drive where your AVD is stored.
