so here is my problem, i need to get a file in phone and then upload it to my parse-server. I've made a file chooser for document, download, external, media folder but android file chooser also propose GoogleDrive option. So i got te Uri but i can't find a way to access that "local copy?".
Do i need to use GoogleDrive SDK to access it? Or can't android just be smart enough and give me methods to handle that Uri ?
I did success getting file name.
content://com.google.android.apps.docs.storage/document/
Here is my file chooser and handler:
public static void pick(final Controller controller) {

chooseFileIntent.setType("application/pdf");
chooseFileIntent.addCategory(Intent.CATEGORY_OPENABLE);

controller.startActivityForResult(chooseFileIntent, Configuration.Request.Code.Pdf.Pdf);

EDIT :
I've made some try but i got a problem when deleting the temporary file
Here is my code:
public static void copyFile(final Context context, final Uri uri, final ParseObject dataSource, final String field, final String name, final Data.Source target, final Handler handler) {
new AsyncTask<Void, Void, Boolean>() {
#Override
protected Boolean doInBackground(Void... params) {
try {
InputStream inputStream = context.getContentResolver().openInputStream(uri);
if (inputStream != null) {
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int length;
while ((length = inputStream.read(bytes)) != -1) {
byteArrayOutputStream.write(bytes, 0, length);
}
dataSource.put(field, new ParseFile(name, byteArrayOutputStream.toByteArray()));
byteArrayOutputStream.close();
inputStream.close();
return true;
} else {
return false;
}
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
#Override
protected void onPostExecute(final Boolean success) {
dataSource.getParseFile(field).saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
if (handler != null) {
handler.success();
}
}
}
}, new ProgressCallback() {
#Override
public void done(Integer percentDone) {
if (handler != null) {
handler.progress(percentDone);
}
}
});
}
}.execute();
}
Final Edit:
Here my code is correct, temporary file are created and put in cache by Parse himself, so its out of my range. Hope he can help.
So i got te Uri but i can't find a way to access that "local copy?".
There is no "local copy", at least one that you can access.
Or can't android just be smart enough and give me methods to handle that Uri ?
Use ContentResolver and openInputStream() to get an InputStream on the content identified by the Uri. Either use that directly with your "parse-server", or use it to create a temporary "local copy" to a file that you control. Upload that local copy, deleting it when you are done.
Here is my file chooser and handler:
pick() is fine. upload() might be fine; I have not used Parse. The rest of that code is junk, copied from prior junk. It makes many unfounded, unreliable assumptions, and it will not work for Uri values from arbitrary apps (e.g., served via FileProvider).

Closed 1 year ago.
I want to get absolute path by Uri, when picking some files from Downloads folder. API level 21+.
Currently I have such errors:
Input Uri: content://com.android.providers.downloads.documents/document/1603
Path: content://downloads/public_downloads/1603
Giving error: java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/1603
or this one:
java.io.FileNotFoundException: /document/msf:64020: open failed: ENOENT (No such file or directory)
java.lang.NumberFormatException: For input string: "msf:64020"
depending on how I access such files. How can I do that properly? Maby you can provide some usuful link to documentation. Thanks.

How optimal is this solution?And is there any better way of handling this?
I am working on project were i have to upload PDF file or DOC file i have write too much codes but no success
whenever i clicked submit Toast say Upload PDF File and Activity exit.
how to solve the problem?
here is the Code i use

if (Intent.ACTION_SEND.equals(action) && type != null) {
if (type.startsWith("image/")) {
handleSendImage(intent); // Handle single image being sent
}
}
}
ContentResolver wasn't working in this case as "_data" field was returning null. So i found another way to get a file from content URI.
In handleSendImage() you need to open inputStream and then copy it into a file.
void handleSendImage(Intent intent) throws IOException {
Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
if (imageUri != null) {
File file = new File(getCacheDir(), "image");
InputStream inputStream=getContentResolver().openInputStream(imageUri);
try {
OutputStream output = new FileOutputStream(file);
try {
byte[] buffer = new byte[4 * 1024]; // or other buffer size
int read;
while ((read = inputStream.read(buffer)) != -1) {
output.write(buffer, 0, read);
}
output.flush();
} finally {
output.close();
}
} finally {
inputStream.close();
byte[] bytes =getFileFromPath(file);
//Upload Bytes.
}
}
}
getFileFromPath() gets you the bytes which you can upload on your server.
public static byte[] getFileFromPath(File file) {
int size = (int) file.length();
byte[] bytes = new byte[size];
try {
BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
buf.read(bytes, 0, bytes.length);
buf.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return bytes;
}
You can get imageFilePath from getRealPathFromUri() below:
String filePath = getRealPathFromUri(this, fileUri);
// You can upload it as File
if (filePath != null && !filePath.isEmpty()) {
File file = new File(filePath);
if (file.exists()) {
// Using Retrofit you can do it like
// create Retrofit Client code......
// creates RequestBody instance from file
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
// MultipartBody.Part is used to send also the actual filename
MultipartBody.Part body = MultipartBody.Part.createFormData("file", file.getName(), requestFile);
// pass body as parameter while execute call
}
}

i'am trying to make a finder to get '.pdf', i got my Uri the file exist but he always return false for File.canRead()
Just before trying to upload that document on my parse server i log this:
final File file = new File(path);
Log.d("=== TAG ====", file.getAbsolutePath());
Log.d("=== TAG ====", String.valueOf(file.exists()));
Log.d("=== TAG ====", String.valueOf(file.canRead()));
Give me this:
06-27 10:58:03.746 24136-24136/bruce.team D/=== TAG ====: /storage/emulated/0/Download/random.pdf
06-27 10:58:03.747 24136-24136/bruce.team D/=== TAG ====: true
06-27 10:58:03.747 24136-24136/bruce.team D/=== TAG ====: false
Then it's just fail uploading after 15 sec, my parse-server isn't access so it must be the read problem !
Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
My way to pick it:
public static void pick(final Controller controller) {
final Intent chooseFileIntent = new Intent(Intent.ACTION_GET_CONTENT);
chooseFileIntent.setType("application/pdf");
chooseFileIntent.addCategory(Intent.CATEGORY_OPENABLE);
if (chooseFileIntent.resolveActivity(controller.getContext().getPackageManager()) != null) {
controller.startActivityForResult(chooseFileIntent, Configuration.Request.Code.Pdf.Pdf);
}
}
So my question why canRead always return false ? How can I read it?
EDIT: The way I get my Path that seems good for me.

Just maybe you dont have permissions to read the file. The file can be stored with permission that doesnt allow you to read in other applications.
Okey so for everyone who can be in the same situation, just re-check if your application didn't loose permission :/ I'am sad
