DummyDroid v2.x FAQ

Can I use DummyDroid to increase the download count of my own app(s)?: No, DummyDroid will not report a download as an installation. This would be against the Google Play Developer TOS anyways and you probably don’t want to risk your account flagged.
Do I have to download ADB?: No, you can use a system installed one. Just make sure it is running before starting DummyDroid and pressing the “probe device” button.
Where does DummyDroid keep its files?: Open the About dialog ( ☰ Help > About ) and click the “Where am I?” button. It will open a file manager in DummyDroid’s main folder.
Why are no apps compatible, even though I probed a real device?: Double check the “Versions” tab in the datasheet. Chances are that you were probing a device with disabled Google Play Services.
Can I change the DummyDroid directory?: Yes! Just pass the desired directory with the workspace system property, e.g.:

java -Dworkspace=/some/place/else -jar dummydroid.jar
