在Android中创建文件路径

Question

Code when I crop an existing image in gallery

 final Uri uri = result.getUri();
 StorageReference thumb_filepath = mStorage.child("Raw").child(UID + ".jpg");
 File thumb_filePath = new File(uri.getPath());
 Log.d("DFGHJKFGHJ", "CREATED FILEEEE" + thumb_filePath);

Logcat Result

 02-23 13:51:20.053 11130-11130/com.appmaster.akash.messageplus D/DFGHJKFGHJ: CREATED FILEEEE/data/user/0/com.appmaster.akash.messageplus/cache/cropped9075402641648633426.jpg

Now I used the same method for getting an image from firebase and converting that to uri and then FIle But the output is different

Code

Uri uri = null;
uri = Uri.parse(String.valueOf(url));
Log.d("DFGHJKFGHJ", "CREATED URI : " + uri);

File thumb_filePath = new File(uri.getPath());
Log.d("DFGHJKFGHJ", "CREATED FILEEEE" + thumb_filePath);

URI is getting created but The output of file is

02-23 13:50:48.326 11130-11130/com.appmaster.akash.messageplus D/DFGHJKFGHJ: CREATED FILEEEE/v0/b/messageplus-cd647.appspot.com/o/hackerpic.jpg

Because of this the next feature is also not working. SO can anyone help me get the output like the first one for firebase image as well please?

Download image from firebase storage and save locally:

private void downloadImgFromFStorageToLocalFile(StorageReference fileRef) {
    if (fileRef != null) {
        progressDialog.setTitle("Downloading...");
        progressDialog.setMessage(null);
        progressDialog.show();

        try {
            final File localFile = File.createTempFile("images", "jpg");

            fileRef.getFile(localFile).addOnSuccessListener(new 
                OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(FileDownloadTask.TaskSnapshot 
                 taskSnapshot) {
                    Bitmap bmp = 
                    BitmapFactory.decodeFile(localFile.getAbsolutePath());
                    imgViewProfile.setImageBitmap(bmp);
                    progressDialog.dismiss();
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    progressDialog.dismiss();
                    Toast.makeText(MainActivity.this, exception.getMessage(), 
                    Toast.LENGTH_LONG).show();
                }
            }).addOnProgressListener(new 
                OnProgressListener<FileDownloadTask.TaskSnapshot>() {
                @Override
                public void onProgress(FileDownloadTask.TaskSnapshot 
                 taskSnapshot) {
                    // progress percentage
                    double progress = (100.0 * 
                      taskSnapshot.getBytesTransferred()) / 
                      taskSnapshot.getTotalByteCount();
                    // percentage in progress dialog
                    progressDialog.setMessage("Downloaded " + ((int) progress) 
                                                            + "%...");
                }
            });
        } catch (IOException e) {
            e.printStackTrace();
        }
    } else {
        Toast.makeText(MainActivity.this, "File ref is null", 
             Toast.LENGTH_LONG).show();
    }
}

Create your own path and save the file

    String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Folder_name";

    File folder = new File(path);
    if (!folder.exists()) {
        folder.mkdir();
    }


 Uri uri = Uri.fromFile(folder);
 File thumb_filePath = new File(uri.toString());
 assertEquals(folder.getAbsolutePath(), thumb_filePath .getAbsolutePath());
