How to download a file from Android emulator

Lloyd Sheen 1,476

As the Android emulator needs to be factory reset every so often I have several files that I create and store on emulator (phone). They are the result of sometimes hundreds of calls to an API so the file makes access to the data much quicker. When I reset the emulator these files are destroyed and have to be recreated so my dev/test time is increase.

What I would like to do is to be able to access the file and put it as a MauiAsset in the solution so it is refreshed when the solution is deployed.

Any direction to how to perform this operation would be appreciated.

To download a file from an Android emulator, follow these steps:

Open the emulator on your computer and navigate to the file you want to download.

Long-press on the file to select it. This will bring up a menu.

From the menu, select the "Share" or "Export" option.

Choose the location where you want to save the file on your computer.

Click "Save" or "Download" to start the download process.

Once the file has downloaded, you should be able to find it in the location you selected. Keep in mind that the download process may vary depending on the emulator you are using.

Could you share with us what file do you want to save? And to which path do you want to save the file?

Alternatively, you can also use adb pull filePathInEmulator localpath instead of device file explorer to pull your file to your local machine, for details pls see Copy files to and from a device

The file's contents hold stats information for about 30 items. These items have between 20 and 30 sub-items. The last file save date is determined and all items which would have new stats are refreshed. To create the file takes about a minute so to ask for the information without the phased update would cause the app to stop for that amount of time which is not good.

The file would be written to string mainDir = FileSystem.Current.AppDataDirectory;

The main problem is that the emulator's time (used to get today to determine which items to refresh) is wrong especially if I have put my workstation to sleep. In that case I have needed to do a factory reset on it thus deleting the file.

Hello,

You can use device file explorer to export your file in android emulator from android studio. After starting your emulator in the VS, you can see this emulator in the device file explorer, expand path and find your file, right click the file and choose Save as, you can save your file from android emulator to your local PC.

By the way, you can add a feature request about adding device file explorer in the Visual Studio as well.

Best Regards,

Leon Lu

I really hate this site. I added (I hoped) that the above answer did not work. I cannot see my reply and so I add it again so that hopefully this site will show it.

I installed Android Studio. I went to the link you sent but it tells me to use a toolbar item but there is no toolbar. I used some of what I could find but the "file" menu item sent me to the folder that the emulator was in and there was no data/data folder as it said.
