How to get the Full file path from URI

2019-01-02 17:55发布

I'd like to get the full file path, from a URI. The URI isn't a Image, but it's a music file, but if i do it like the MediaStore Solution, it won't work if the app user selects eg Astro as browser, instead of Music Player. How do I solve this?

I had a hard time trying to figure this out on Xamarin. From the suggestions above I came up with this solution.

private string getRealPathFromURI(Android.Net.Uri contentUri)
{
    string filename = "";
    string thepath = "";
    Android.Net.Uri filePathUri;
    ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);

    if (cursor.MoveToFirst())
    {
        int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
        filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
        filename = filePathUri.LastPathSegment;
        thepath = filePathUri.Path;
    }

    return thepath;
}

You can use get File path from diffrent SDk versions

Use RealPathUtils for it

public class RealPathUtils {

@SuppressLint("NewApi")
public static String getRealPathFromURI_API19(Context context, Uri uri){
    String filePath = "";
    String wholeID = DocumentsContract.getDocumentId(uri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ id }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();
    return filePath;
}


@SuppressLint("NewApi")
public static String getRealPathFromURI_API11to18(Context context, Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    String result = null;

    CursorLoader cursorLoader = new CursorLoader(
            context,
            contentUri, proj, null, null, null);
    Cursor cursor = cursorLoader.loadInBackground();

    if(cursor != null){
        int column_index =
                cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        result = cursor.getString(column_index);
    }
    return result;
}

public static String getRealPathFromURI_BelowAPI11(Context context, Uri contentUri){
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
    int column_index
            = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
}

**Now get the file Path from URI **

 String path = null;
                if (Build.VERSION.SDK_INT < 11)
                    path = RealPathUtils.getRealPathFromURI_BelowAPI11(MainActivity.this, uri);

                    // SDK >= 11 && SDK < 19
                else if (Build.VERSION.SDK_INT < 19)
                    path = RealPathUtils.getRealPathFromURI_API11to18(MainActivity.this, uri);

                    // SDK > 19 (Android 4.4)
                else
                    path = RealPathUtils.getRealPathFromURI_API19(MainActivity.this, uri);
                Log.d(TAG, "File Path: " + path);
                // Get the file instance
                 File file = new File(path);

Use:

String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

or

String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

Try this.

public String getRealPathFromURI(Uri contentUri) 
{
     String[] proj = { MediaStore.Audio.Media.DATA };
     Cursor cursor = managedQuery(contentUri, proj, null, null, null);
     int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
     cursor.moveToFirst();
     return cursor.getString(column_index);

The PathUtil method will be only working in below oreo and if it is oreo than it is likely to crash because in oreo we will not get the id but the entire path in data.getData() so all u need to do is create a file from uri and get its path from getPath() and split it.below is the working code:-

Uri uri = data.getData(); 
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).

The above code will work in oreo and if it is below oreo than PathUtil will work.Thanks!

String filePath=PathUtil.getPath(context,yourURI);
