Speeding Up the Android Emulator

Here are several tips explaining methods I've discovered for improving the performance of the Android AVD:

1. Enable Snapshot: Navigate to the AVD Manager in Eclipse via Window->AVD Manager. Select your AVD of choice and click Edit. Within the Snapshot section, fill the checkbox near Enabled.

2. Lower the Resolution: Inside the same screen where we changed Snapshot, select the bubble next to Built-in within the Skin section. From the adjacent drop-down, select QVGA. This is the lowest resolution natively offered by Android (240 x 320). I do not recommend going lower than this, as it may cause visual aspects to begin to come askew. 

3. Change Device RAM Size: Inside that same screen, under Hardware, you can configure Device RAM Size to whichever value you'd prefer. Obviously a greater RAM dedication will increase the performance of the AVD, but will also decrease the performance of all your other processes.

Your settings should now look something like this:



I do not advise messing around with the Abstracted LCD density or the Max VM application heap size, as these can cause some instability in the screen refresh rate and the memory usage, respectively.
