My app will read and write .db and .txt files in a directory in Downloads.
I already select and request that folder access permission like this:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intent, REQUEST_CODE_FOR_DIR);
It works fine if the directory is empty and create those files from app.
If I want to read or edit those files already exist will cause error:
W/System.err: java.io.FileNotFoundException: /storage/emulated/0/Download/app_Folder/test.txt: open failed: EACCES (Permission denied)
I'm trying not to ask ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION.
How to let my app access those already exist files without using file selector?
When I tried to convert the file selected by the user to request body, I got the error FileNotFound, open failed: EACCES (Permission denied) on Android 12. I was trying to upload a user-selected pdf using Retrofit Multipart Upload.
For calling intent I have used ACTION_OPEN_DOCUMENT
file.asRequestBody("multipart/form-data".toMediaTypeOrNull()
Do I need to use MANAGE_EXTERNAL_STORAGE permission?
I am not able to send selected file to server using multipart in android 11, I am able to send till android 10 but on android 11 it gives exception
targetSdkVersion: 29
requestLegacyExternalStorage=true in Manifest.xml
java.io.FileNotFoundException: /storage/dir/file.txt : open failed: EACCES (Permission denied)
i'm new to kotlin and android i'm trying to read build.prop from /system for that i'm accessing root by using
Runtime.getRuntime().exec("su")
and i also gave storage permission(i have done all the stuffs needed to access storage that need to work on Android 10 like fileProvider and such things)
here is the code of accessing build.prop file
private fun filecreator(): String {
val ensy= Environment.getRootDirectory()
val filess =File("$ensy","build.prop")
return filess.readText()
}
after it throws
msg: android.system.ErrnoException: open failed: EACCES (Permission denied)
stacktrace: java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.airbender.c2/com.airbender.c2.MainActivity}: java.io.FileNotFoundException:
/system/build.prop: open failed: EACCES (Permission denied)
what should i do is there any way to access /system or my implementation is totally wrong
thanks

For some strange reason, am constantly facing an issue with different types of Android devices, for saving the captured images on the device storage.
Here, is the detailed error log, of what, actually am getting.
java.io.IOException: open failed: EACCES (Permission denied)
at java.io.File.createNewFile(File.java:940)
at com.parkhya.pick_for_shareAflash.HomeActivity.resizeImage(HomeActivity.java:456)
at com.parkhya.pick_for_shareAflash.HomeActivity.onActivityResult(HomeActivity.java:393)
Caused by: libcore.io.ErrnoException: open failed: EACCES (Permission denied)
at java.io.File.createNewFile(File.java:933)
Although, all the other Android apps, like, Instagram and others, are able to save the camera clicked images on the devices.
Anybody, can you please suggest, what should I do, in order for my app, to save the camera pictures in sdcard.
This may help you. I face the same issue when writing the file on sdcard. I have set all required permission to write the file but I used the file object like below:
Wrong:
File myFile = new File(Environment.getExternalStorageDirectory().getAbsoluteFile()+fileName);
Correct:
File myFile = new File(Environment.getExternalStorageDirectory().getAbsoluteFile(), fileName);
That means the path was wrong.
Solution what i find is
edit the Emulator
1. go to android virtual device manager and then edit the emulator
2. set say 100 MB for Sd card for the respected emulator and say Ok
3. save and close emulator and start
4. path saved is click DDMS mnt/sdcard/yourfilename
it worked for me the app is not giving Error and is working
