Where is the Application.Current.Properties located on Android?

You can directly check the source code on github and try to figure out where the storage location is .

Search the file Application , and inside the class search keyword Properties .

public IDictionary<string, object> Properties
{
    get
    {
        if (_propertiesTask == null)
        {
            _propertiesTask = GetPropertiesAsync();
        }

        return _propertiesTask.Result;
    }
}

async Task<IDictionary<string, object>> GetPropertiesAsync()
{
    var deserializer = DependencyService.Get<IDeserializer>();
    if (deserializer == null)
    {
        Log.Warning("Startup", "No IDeserialzier was found registered");
        return new Dictionary<string, object>(4);
    }

    IDictionary<string, object> properties = await deserializer.DeserializePropertiesAsync().ConfigureAwait(false);
    if (properties == null)
        properties = new Dictionary<string, object>(4);

    return properties;
}

Search the file IDeserializer and its implementation on Android platform.

using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
{
    if (!store.FileExists(PropertyStoreFile))
        return null;

    using (IsolatedStorageFileStream stream = store.OpenFile(PropertyStoreFile, System.IO.FileMode.Open, System.IO.FileAccess.Read))

Search the file IsolatedStorageFile and its implementation on Android platform.

public class _IsolatedStorageFile : IIsolatedStorageFile
{
    readonly IsolatedStorageFile _isolatedStorageFile;

    public _IsolatedStorageFile(IsolatedStorageFile isolatedStorageFile)
    {
        _isolatedStorageFile = isolatedStorageFile;
    }

    public Task CreateDirectoryAsync(string path)
    {
        _isolatedStorageFile.CreateDirectory(path);
        return Task.FromResult(true);
    }

At last , the implementation for CreateDirectory is hidden , so that we can't get the exact file path , however I just show you how to get something from source code .

The Xamarin Forms storage location of Application.Current.Properties on Android is:

/data/data/YOUR_PACKAGE_NAME/files/.config/.isolated-storage/PropertyStore.forms

Test

In the Xamarin persist some property:

Application.Current.Properties["someKey"] = "someValue";

Afterwards:

adb root
adb shell
cd /data/data/YOUR_PACKAGE_NAME/files/.config/.isolated-storage/
ls
