Android: Files: Unable to get file path from content URI when file is selected from RECENT section in file browser

I was trying to fetch file path from Uri given by data.data!! onActivityResult() method in android. When I selected the DCIM folder in File browser I was able to get the file path but when I selected the same file from RECENT section in file browser I was not getting the file path.
Code on Button click:
val intent = Intent();
intent.setType("image/*");
val mimeTypes: Array<String> = arrayOf("image/*", "application/pdf")
intent.putExtra(Intent.EXTRA_MIME_TYPES,mimeTypes)
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivityForResult(Intent.createChooser(intent, "Select File"), 101);
Code on returning data from onActivityResult() method:
var selectedImagePathFB:String = ""
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == RESULT_OK) {
if (requestCode == 101) {
val selectedImageUri:Uri = data?.data!!
selectedImagePathFB = getPath(this#MyContactUsActivity,selectedImageUri);
//selectedImagePathFB = AppUtils().getRealPathFromURI(this#MyContactUsActivity,selectedImageUri)
val url: String = selectedImagePathFB
}
}
}
and getPath(Context,Uri) is common found code from stackoverflow by paulburke:
public static String getPath(final Context context, final Uri uri) {

I am testing on android Q device. Why is that when selecting file from RECENT section in file browser i am not getting any file path meanwhile selecting same file in STORAGE section is returning file path? And is there a workaround also for converting files like PDF or Images in Base64 string if not from file path?

According to your code there is no error. But you have to get Storage permission before getting files from Recent section. Read and Write permission are required.

Intent.getData().getPath() not returning the actual path?

I am designing an application where the user selects a text file from the memory and the app speaks it out. I am using Intents to do it.
My onActivityResult() looks like this.
protected void onActivityResult(int reqCode, int resCode, Intent data){
if(resCode == Activity.RESULT_OK && data != null){
Uri u = data.getData();
String str = u.getPath();
Toast.makeText(this, "str", Toast.LENGTH_LONG).show();
//File file = new File(str);}}
So initially, I was getting the path using which I was able to read the file. But know, it is returning /external/file/6433. No matter how deep my file is situated, it will return /external/file/number.
Kindly tell me what I need to do to get the actual path i.e. /storage/emulated/0/.

The string that you get from intent actually is the URI for the file. You can use this method to get the actual path. I put this code in my Utils class. The code is quite long. You can refer to actual Utils class here : Utils.getPath
public static String getActualPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
// TODO handle non-primary volumes
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
}
// MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[] {
split[1]
};
return getDataColumn(context, contentUri, selection, selectionArgs);
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
and make some changes onActivityResult
Uri u = data.getData();
String filePath = Utils.getActualPath(this, u);
Toast.makeText(this, filePath, Toast.LENGTH_LONG).show();

How to get an image from the gallery, get its name, save it in the internal memory and get the route of that image

(I apologize if I make mistakes writing in English)
I need to do the same as the title says
I only know how to get the image from the gallery. I think this is correct:
(If it is wrong or it is inefficient please let me know)
private final int SELECT_PICTURE = 200;
btnAddImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent galeryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galeryIntent.setType("image/*");
startActivityForResult(galeryIntent.createChooser(galeryIntent, "Sececiona Imagen"), SELECT_PICTURE);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case (SELECT_PICTURE):
if(requestCode == RESULT_OK){
Uri path = data.getData();
}
}
break;
}
}
But I don't know how to get the name of the image that I caught from the gallery and save it whit that name in the internal memory of my app.
Then I need the route of the image like "MyAPP/media/ ..." , I don't know the correct name in English for that, and save it in my database (save it in my database is easy) and then use it in my project
I know this is a long message but I need your help because in the Spanish forum of StackOverflow anybody answered me.

onActivityResult :
String path = getPath(getApplicationContext(), data.getData());
File mFile = new File(id);
mFile.getName();
That is the way that a got the name of the file.
And the getPath :
public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Log.d("Lucas","TYPE => "+type);
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
} else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
} else if (isMediaDocument(uri)) {

How to convert From string to image file

I am developing a simple android photo uploader. I have a Gallery activity, there I can select the pictures. After that I am sending the image names with path because i need to show them.
How can I make files out of these names and point to the actual image for the upload?
String[] picturesWithPath = new String[arrPath.size()];
for (int z = 0; z < arrPath.size(); z++)
{
picturesWithPath[z] = arrPath.get(z);
Log.i("data","with path: "+picturesWithPath[z]);
}

Use bellow code for get file URL.
//use this in yorr for loop
picturesWithPath[z] = getPath(Yourclass.this, arrPath.get(z));
public static String getPath(final Context context, final Uri uri) {
// check here to KITKAT or new version
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {

Android how can i get thumb image of video file from gallery

I need to show the selected video file from gallery in my listview.
I have successfully fetched the uri of video file but i am not able to get the thumb image of video file. Here is the code i have used for fetching image of video file from uri, but is causes the app to crash. Is there any other way to get image of video file..? please assist me if it can be achieved in any other way....
public static String getFileMetaData(Context context,String uri){
Uri queryUri = Uri.parse(uri);
// Get relevant columns for use later.
String[] projection = {
MediaStore.Files.FileColumns._ID,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.MEDIA_TYPE,
MediaStore.Files.FileColumns.MIME_TYPE,
MediaStore.Files.FileColumns.TITLE
};
// Return only video and image metadata.
String selection = MediaStore.Files.FileColumns.MEDIA_TYPE + "="
+ MediaStore.Files.FileColumns.MEDIA_TYPE_IMAGE
+ " OR "
+ MediaStore.Files.FileColumns.MEDIA_TYPE + "="
+ MediaStore.Files.FileColumns.MEDIA_TYPE_VIDEO;
CursorLoader cursorLoader = new CursorLoader(
context,
queryUri,
projection,
selection,
null, // Selection args (none).
MediaStore.Files.FileColumns.DATE_ADDED + " DESC" // Sort order.
);
Cursor cursor = cursorLoader.loadInBackground();
int columnIndex = cursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA);
Log.d("MyTag","***************** : " + cursor.getString(columnIndex));
cursor.close();
return null;
}

Fixed this problem with some changes. Actually my problem was the file path that i had given is wrong.I have been giving the Uri got from gallery,
now i had changed the code for getting the real path from Uri and
then applied them to ThumbnailUtils for creating thumb image.
Uri uri = Uri.parse(uri);
String mUri = AppUtils.getRealPathFromURI(mActivity,uri,"VIDEO");
mImageSend.setImageBitmap(ThumbnailUtils.createVideoThumbnail(
mUri, MediaStore.Video.Thumbnails.FULL_SCREEN_KIND));
public static String getRealPathFromURI(Context context,Uri contentURI,String type) {
String result = null;
try {
Cursor cursor = context.getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
Log.d("TAG", "result******************" + result);
} else {
cursor.moveToFirst();
int idx = 0;
if(type.equalsIgnoreCase("IMAGE")){
idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
}else if(type.equalsIgnoreCase("VIDEO")){
idx = cursor.getColumnIndex(MediaStore.Video.VideoColumns.DATA);
}else if(type.equalsIgnoreCase("AUDIO")){
idx = cursor.getColumnIndex(MediaStore.Audio.AudioColumns.DATA);
}
result = cursor.getString(idx);
Log.d("TAG", "result*************else*****" + result);
cursor.close();
}
} catch (Exception e){
Log.e("TAG", "Exception ",e);
}
return result;
}

From the video file uri first you have to get filepath of video file then from filepath you can generate video thumb.
You can get thumbnail using createVideoThumbnail method of ThumbnailUtils class like this.
video_imageview.setImageBitmap(ThumbnailUtils.createVideoThumbnail(selectedVideoFilePath, MediaStore.Video.Thumbnails.FULL_SCREEN_KIND));
In which selectedVideoFilePath is video file path. You can get file path using this.
String selectedVideoFilePath = GetFilePathFromDevice.getPath(this, videoFileUri);
You can use GetFilePathFromDevice class to get filepath from given Uri.
GetFilePathFromDevice.java
