Mac OS X 10.10 (Yosemite) or higher, up to 10.14 (macOS Mojave), GNOME or KDE desktop. Say I do this: SQLiteDatabase db db yourAppContext.openOrCreateDatabase('db.sqlite3', Context.
There may be other ways to copy files from your local computer’s filesystem onto the Android emulator’s filesystem, but I can confirm that (a) this approach works, and (b) I got the “read-only file system” error until I ran this series of commands. The Android Emulator only supports 64-bit Windows. I am using Android Studio on a Mac, everything on the latest version. The transfer rate and number of bytes output helps to show that the file was copied to the emulator successfully. Now back at my local filesystem prompt, I was then able to copy my file to the Android emulator filesystem using the adb push command, like this:Īs that command infers, the file foo.jpg was located in my local Mac directory. One of the biggest advantages of using Android Emulator is that we can do almost everything as if we were working with a physical device.And of course, it also has a SIM card number, which makes it possible to simulate a phone call (or send a message) to Android Emulator.
In the following sequence, I issued the first command from my Mac/Unix operating system shell, and then the subsequent commands were run inside the adb shell: Open SQLite Database Stored in Device using Android Studio 1. I did that using the following series of commands.
ORM stands for Object Relational Mapping an API that lets you save and retrieve 'objects' from a database without writing SQL statements. While it takes various methods to access these database files, interacting is exactly the same on all when using the sqlite3 tool. The SQLite.NET library that Xamarin recommends is a very basic ORM that lets you easily store and retrieve objects in the local SQLite database on an Android device. The solution to this problem was to re-mount the emulator’s filesystem as a read-write filesystem. Now that you’ve found your app’s SQLite database, here’s a hadful of useful commands to inspect its state and contents. adb pull /data/data/de.dotnetco/files/myapp.db3 /Users/ username/Downloads/myapp.db3. So in your command prompt, use pull to a copy of your SQlite database to your mac, e.g. $ adb push foo.jpg /data/data//filesįailed to copy 'foo.jpg' to 'foo.jpg': Read-only file system As already written above, your database location on your emulator might be something like /data/data/de.dotnetco/files/myapp.db3. When I tried to copy a file using this command:
However, I just ran into a problem where I couldn’t copy files to my Android emulator’s “data” directory, i.e., the /data/data filesystem. As an Android developer, you can normally use the adb push command to copy files from your computer’s hard drive to an Android device.
