Now i want to save the path of a pdf file created and saved in internal storage to be saved in my sqlite database. I know how to store values into database i just wanna know how to get the path of a file stored in my internal storage??
"i just wanna know how to get the path of a file stored in my internal storage??"
Have you tried getFilesDir()? Example.
String path = this.getFilesDir().toString()+"/"+nameOfFile;
You can use the Environment.getExternalStorageDirectory()
This method returns the primary external storage directory.
For example, if you have a folder called /pdf, so the path of your file will be:
Environment.getExternalStorageDirectory() + "/pdf/" + <pd_file_name>
Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

I want to create an activity to search for users by full name. I created everything I needed and it worked properly, except for one thing. When I press search button the result are not show in recyclerview. I need to go back and the the results are shown. I need to do these 2 steps to see the results.
Yes the search bar and view holder are overlap, I will try to fixed later. Do you know how to make it so that once searched the results are displayed immediately without having to go back
This is my layout for view holder

I think it's the RecyclerView in your XML that needs to be adjusted at android:layout_height = "0dp"
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="0dp"

For some reason, the PDF just isn't being displayed on screen, I keep getting a white, blank background. What am I doing wrong? Is the path incorrect? I have no SD card on my device. Or am I doing something wrong with the bitmap?
Is the path incorrect?
Yes.
I have no SD card on my device
That is fine. That would be removable storage. I am interpreting "Download/Adobe Reader/answerkey.pdf" as referring to something on external storage.
The recommended way to get this location would be to replace:
File file = new File(Environment.getDataDirectory().getPath()+"Adobe Reader/answerkey.pdf");
with:
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "Adobe Reader/answerkey.pdf");
Note that your app will need to request the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permission, and that will involve runtime permissions on Android 6.0+ (if your targetSdkVersion is 23 or higher).
That is my code java
intent.putExtra(Intent.EXTRA_SUBJECT, "My App name and some text");
intent.putExtra(Intent.EXTRA_TEXT, "a link");
intent.putExtra(Intent.EXTRA_STREAM,getImageUri(context,mBitmap));
intent.setType("image/*,text/plain");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
I want to share image and text. This code works on WhatsApp, Twitter, Gmail , etc .. but it does not work on Facebook
thank you in advance for your help
If you want to share the Image and text on Facebook without using Facebook SDK then you have to create the bitmap of your image plus text and then you can share that bitmap on facebook.
Download the source code from here (Share image and text on facebook using intent in android)

You can share int value of an image as R.drawable.image and get it with getResources.getDrawable(int)

What's the problem? I really need your help
