I'm migrating from HTTP to HTTP v1 for notification in android studio. have added Service-account.jason file to assets folder. But i'm not able to access the file while trying to send
notification.
getting below error:
java.io.FileNotFoundException: service-account.json: open failed: ENOENT (No such file or directory)
I have an app which records videos, it has about 80K current installations (more than 100K downloads), Crashlytics statistics seems to be good - Crash-free users 99.66% and rating on Google Play is also OK - 4.5
But still for some of my users can happen the next error (it may happened for each user once or a couple of times by now, so not often, but still happens from time to time):
java.io.FileNotFoundException:
/storage/7886-1D16/Android/media/MY_APP_PACKAGE_NAME_HERE/2021-03-18
21h 18m 06s.mp4: open failed: EROFS ... blah blah blah ... android.media.MediaRecorder.prepare(MediaRecorder.java:1028)
Here's the code (similar to real one in my project), as you can see before mediaRecorder.prepare() and video recording I check if output directory is good, if File.canWrite() returns true then it means that files exists, app has needed permission to write at this path and storage is mounted https://developer.android.com/reference/java/io/File#canWrite()
// canWrite() - means that file exists and app is allowed to write
if (outputFolderFile.canWrite()) {
// directory is OK, Android says that there is nothing wrong...
val videoFile = File(outputFolderFile, videoFileName)
... // MediaRecorder settings
mediaRecorder.setOutputFile(videoFile.absolutePath)
... // other MediaRecorder settings
try {
mediaRecorder.prepare() // FileNotFoundException here from time to time
} catch (e: Exception) {
e.printStackTrace()
openReportErrorDialog(e)
}
}
Additionally I was trying to add && Environment.getExternalStorageState(outputFolderFile).equals(Environment.MEDIA_MOUNTED)) or || (outputFolderFile.mkdirs() && outputFolderFile.canWrite()) to that condition (outputFolderFile.canWrite()) but it doesn't matter, error still happens
I also was trying to add createNewFile(videoFile ) line before mediaRecorder.prepare() but doesn't help and in this case the error is java.io.IOException: No such file or directory, java.io.IOException: No such file or directory at java.io.UnixFileSystem.createFileExclusively0(Native Method)
So Android says that directory exists, everything is ok and app can write files there but...
Here I almost added all reports from my users about this error:

So it mostly happens for Xiaomi devices, and mostly when recording to external micro SD Card (e.g. path is /storage/2A2C-40A4/***), though for built-in storage of phone (/storage/emulated/0/***) it also happens sometimes...
Versions of Android are different, from 6 (old) to 11 (newest), so it doesn't matter.
You can see that error is similar (starting with FileNotFoundException and file absolute path) but sometimes it changes at the end between
open failed: EROFS (Read-only file system)
open failed: ENOENT (No such file or directory)
open failed: EIO (I/O error)
open failed: EPERM (Operation not permitted)
Of course users don't send such error report everyday but still it happens often.
I don't have any idea why it happens. I can't reproduce this issue on my own devices (two Samsung, one Lenovo, one Huawei and one Xiaomi devices).
Maybe it happens because read/write time to storage was very slow or freezed (heavy load on it storage controller) at this point and Android (MediaRecorder) could not create an output video file for recording?
Any ideas or solutions?
p.s. full example of error:

Caused by: java.io.FileNotFoundException: /RecordsKeeper/address/src/main/res/config.properties: open failed: ENOENT (No such file or directory)
I am getting the above error while I run my application. I am not able to load my config.properties file from config.java while I'm running my android application. Although it gets loaded and works fine when I run my library test cases using that config file.
In my app, I am getting info about device storage (total and free space) using StatFs class.
It is initialized this way:
StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath());
This app has a bug reporting tool that reports the follwoing error in the previous piece of code:
android.system.ErrnoException
Posix.java line -2 in Posix.statvfs()
statvfs failed: ENOENT (No such file or directory)
I've found little info about this error, like here and here
The documentation about ErrnoException says: A checked exception thrown when Os methods fail.
Someone else has faced this issue?
I am working at a app which is started from a browser - I am trying with FireFox - I get the file Uri from the Intent but I can not open the file in this path :
java.io.FileNotFoundException: /file:/storage/emulated/0/Download/baningmyheadreallyhard.txt: open failed: ENOENT (No such file or directory)
Any idea about why ?
