I want to get the emulated storage path. System.getenv("EMULATED_STORAGE_TARGET") works on previous versions i.e Android 5 and below but returns null on Android 6. I searched on google but couldn't find anything. How can I get the emulated storage path on Android 6. Any help will be appreciated. Thanks in advance!!
You appear to be referring to external storage, which on some versions of Android will be located at /storage/emulated/0/. The proper way to obtain the root of external storage, on all versions of Android, is by means of Environment.getExternalStorageDirectory().
If you find yourself using environment variables in an Android app, you are doing it wrong.

So I'm making an app that requests a file from the phone's storage (external storage - not external SD Card, the internal one). But the path is awkward when I select the file from Downloads: /document/[number here, for example, 4].
Does anyone know how to get the real path of that file? Because it exists on the Download folder, but I wanted it to when it's selected, I get the real path of it and not that weird path which actually doesn't even exist. This happens at least on Nougat (Android Studio emulator) and on KitKat (both the emulator and my phone). Any help is appreciated.
As pointed by Abhay Koradiya and Nandan Desai, the path was an Uri path, so I used this code to solve the problem and convert to normal path, given by Abhay Koradiya: http://technophilegeek.blogspot.com/2018/11/android-get-file-path-from-uri-real.html. Again, thank you both for the help!
I've tried a lot of method and I've read a lot of posts, without find a valid soluction.
Summing:
I try to use this https://github.com/18446744073709551615/android-file-chooser-dialog to choose a directory and use it. This code work perfectly with internal storage.
With this code: System.getenv("SECONDARY_STORAGE"), on my Asus TF201 with JellyBean and with Lollipop, I have /storage/sdcard1 and I can use this with previus code and it works.
Now, the problem.
I've tried with this (and other similar solution): How can I get external SD card path for Android 4.0+? but on LG G3 with Android 6.0 I've /mnt/media_rw/9014-4EF8 and doesn't work with previous code.
How can I obtain the external sd path? I need only to read in sd. Or can I use /mnt/media_rw/9014-4EF8?
I am trying out a test application on an Android emulator. I would like the app to write data to a file that is stored on my C drive. I have read and written data off Samba drives and webservices, but reading and writing to my local hard seems to be a puzzle. I tried filePath = "file:///C:/test/input/"; to point it as my parent folder, but the Emulator doesn't seem to recognize the directory, and I get a 'not found' error.
Any ideas will be appreciated. Thanks.

That is not possible, unless that file is accessible via some server. The Android SDK emulator does not have access to the filesystem of the developer PC.
Given that you are using an android emulator I am guessing it is setting up some special folder to act as a proxy for the androids hard drive. Meaning that the android emulator doesn't understand what your C drive is and instead is looking in it's 'hard drive' for a file. Find out where the emulator puts files for android, it could be a temp folder, and store your file there.
Edit: Where is Android Emulator Internal Storage this question should help you find where the files should be stored and the naming conventions.
If you don't care using genymotion emulator instead you can refer to this answer, pointing to this post, it has just what you need
On Android 4.4.2 Environment.getExternalStorageDirectory().getPath() returns /storage/emulated/0 but this path does not exist on my Nexus5 Android 4.4.2. Environment.getExternalStorageDirectory().getPath() worked up until Android 4.4.2.
How can I get the /sdcard path on Android 4.4.2?
This path does not exist on my Nexus5 Android 4.4.2.
Yes, it does, for your process at runtime.
For example, this sample project downloads a file to Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS). If you log the location at runtime, when running it on a Nexus 5, it is reported as /storage/emulated/0/Download. And the download succeeds.
If you are looking for /storage/emulated/0 via DDMS or adb shell, you will not find it. For those tools, default external storage is /mnt/shell/emulated/0. Hence, the downloaded file from the above sample appears in the /mnt/shell/emulated/0/Download directory.
AFAIK, the difference is tied to providing separate external storage to secondary accounts.
The Storage Options documentation says to use Environment.getExternalStorageDirectory() (as you are already correctly using). This function is available on all versions of Android.
Are you seeing it return a path that isn't actually available on a 4.2 device?
Please note (from Environment.getExternalStorageDirectory()):
Applications should not directly use this top-level directory, in order to avoid polluting the user's root namespace. Any files that are private to the application should be placed in a directory returned by Context.getExternalFilesDir, which the system will take care of deleting if the application is uninstalled. Other shared files should be placed in one of the directories returned by getExternalStoragePublicDirectory(String).
Writing to this path requires the WRITE_EXTERNAL_STORAGE permission, and starting in read access requires the READ_EXTERNAL_STORAGE permission, which is automatically granted if you hold the write permission.
Starting in KITKAT, if your application only needs to store internal data, consider using getExternalFilesDir(String) or getExternalCacheDir(), which require no permissions to read or write.
Sometimes /storage/emulated/0 can be written to, but reads fail... so tests for "writability" are not sufficient. This is such an annoying problem, I have come up with an equally annoying but effective solution.
Hardcode "/mnt/sdcard" Yea, I said it.
Looks like someone else said it first ... storing android application data on SD Card

I want to develop a code to browse the all folders and files in android emulator including sd card and internal memory storage. In Java there is JFileChooser available, in android how can i implement this functionality...?
You cannot browse all files in an Android device unless it is rooted. You need to have root privileges to access most of the file system (and you don't...).
Also, AFAIK there is no such API, but read data storage section in the android documentation to see what you can do.
This should help you

i.e. As a widget not available , but you can use an app called OI File Manager and use its properties
