How to directly get Content URI for PDF document to other application from file path?

public class MainActivity extends Activity {
Button Send;
Button attachment;
TextView tvAttachment;
String email;
String subject;
String message;
Uri URI = null;
private static final int PICK_FROM_GALLERY = 101;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
sendEmail();
}
});
//attachment button listener
attachment.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openFolder();
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_FROM_GALLERY && resultCode == RESULT_OK) {
URI = data.getData();
tvAttachment.setText(URI.getLastPathSegment());
tvAttachment.setVisibility(View.VISIBLE);
}
}
public void sendEmail() {
File file = new File(Environment.getExternalStoragePublicDirectory
(Environment.DIRECTORY_DOWNLOADS), "ADSB.pdf");
try {
String email = "xyz#abc.com";
String subject = "Mail Subject Required";
String message = "Testing mails";
final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{email});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
if (URI != null) {
emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
}
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
this.startActivity(Intent.createChooser(emailIntent, "Sending email..."));
} catch (Throwable t) {
Toast.makeText(this, "Request failed try again: "+ t.toString(), Toast.LENGTH_LONG).show();
}
}
public void openFolder() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_GALLERY);
}
}
From the code above, I can select the desired PDF file and send the content URI to Mail application.
But I want to directly get the content URI from the absolute address of the pdf file(Without choosing the pdf file from the location as the location is already known). I am not getting how to do this.

I am working on OCR reader application. below is my java code. My question is how to start another method if one is completed?

When the user captures the image, the device will automatically read aloud the text. for that i have implemented texttospeech method but when this activity stop i want to start another task. how will it can be done?
After reading the captured text, I want to implement another text-to-speech method how can i do this?

just use the same mode on text to speech ADD and it will play when the first one is done, ADD = ADD, FLUSH = reset
textToSpeech.speak("this will play when first is done",
TextToSpeech.QUEUE_ADD, null);

You have to call startVoiceInput() again.
You are setting this call for an onClick() handler on a TextView already.

Null image on firebase storage. How to save it original?

I have tried to solve an issue on my app but I couldn't find a solution. I want the app to upload the images on Firebase Storage after the post is clicked. The problem is that when I click post the images are uploaded as .null and I can't add them as posts on my app here is a photo of Firebase Storage:
Here is the code of PostsActivity:

}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {

if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
myUrl = downloadUri.toString();
DatabaseReference reference = FirebaseDatabase.getInstance().getReference("posts");
String postId = reference.push().getKey();
HashMap<String, Object> hashMap = new HashMap<>();
hashMap.put("postId", postId);
hashMap.put("postImage", myUrl);
hashMap.put("description", description.getText().toString());
hashMap.put("publisher", FirebaseAuth.getInstance().getCurrentUser().getUid());
reference.child(postId).setValue(hashMap);
progressDialog.dismiss();
startActivity(new Intent(PostActivity.this, MainActivity.class));
finish();
}else {
Toast.makeText(PostActivity.this, "Failed.", Toast.LENGTH_SHORT).show();

image_added.setImageURI(imageUri);
}else {
Toast.makeText(this, "Something gone wrong", Toast.LENGTH_SHORT).show();
startActivity(new Intent(PostActivity.this, MainActivity.class));
}
}
}
I thought that I have to initialize Uri inside onCreate method but nothing changed. What should it be?

I found the solution for anyone else who has the same issue, the solution is that I should have added a ! into this if, like this:
if (!task.isSuccessful()) {
throw task.getException();
}

It has been noticed that the method you are using to retrieve the file mime type doesn't work on some devices. You could try some other alternatives like using apache commonsIO lib or alternatively try this code :
public String getMimeType(Uri uri) {
String mimeType = null;
if (ContentResolver.SCHEME_CONTENT.equals(uri.getScheme())) {
ContentResolver cr = getAppContext().getContentResolver();
mimeType = cr.getType(uri);
} else {
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
.toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
fileExtension.toLowerCase());
}
return mimeType;
}

"How to fix "Image not uploading into firebase-storage using Picasso library"

I'm trying to make a profile activity where user's data will be shown and also user can edit their data also. Everything works fine. There is no error showing in the code but when i'm trying to upload an image using camera or gallery. It's not uploading in the firebase storage. Also no "Toast" message shows.

Image is not uploading from my gallery through Bitmap

This is my RegistrationActivity.java where I want user to choose image while registering time. Everything works fine except image updation! When I register a new user and when I click in image, it opens my image gallery, I choose any image, and it back to register activity but it won't update. Also I'm unable to register because that image is not uploading successfully and I sat (if
imagepath == null), so that's why toast error is coming that fill all the details.
NOTE:
1. I tried multiple images, same issue, also I resize some images and tried.
2.There is no error in logcat.
3.Default image is showing perfectly when we first time try to register that time I sat android logo which is default.
4.I can't register without selecting any image because imagepath == null and I exactly want that user should not register if he/she not upload the image.
5.I sat imageview size :
android:layout_width="150dp"
android:layout_height="150dp"
in my activity_registration.xml file. Is there cause any problem?
