I'm trying to cat files in Android sysfs, and first I'd like to check if the files exist, and if they are accessible. I'm trying the first step with the following Java code String filePath = "/sys/some/path/to/some/file"; try { File file = getApplicationContext.getFileStreamPathfilePath; if { // do something } else { // do something else } } catch IOException e { } At run time, I get a File /sys/some/path/to/some/file contains a path separator What am I doing wrong, and how can I check if a file in sysfs is readable? asked Feb 17, 2017 at 739 user1118764user11187649,17518 gold badges60 silver badges112 bronze badges 2 Try this code - String fileDirectory = "/sys/some/path/to/some/"; String fileName = "file"; try { File file = new FilefileDirectory, fileName ; if { // do something } else { // do something else } } catch IOException e { } answered Feb 17, 2017 at 820 I ended up using vivek's suggestion to use FileInputStream, and then checking for exceptions answered Feb 20, 2017 at 949 user1118764user11187649,17518 gold badges60 silver badges112 bronze badges

The majority of apps that require shared storage access can follow the best practices for sharing media files and sharing non-media files. However, some apps have a core use case that requires broad access to files on a device, but can't access them efficiently using the privacy-friendly storage best practices. Android provides a special app access called all-files access for these situations. For example, an anti-virus app's primary use case might require regular scanning of many files across different directories. If this scanning requires repeated user interactions to select directories using the system file picker, it provides a poor user experience. Other use casesâsuch as file manager apps, backup and restore apps, and document management appsârequire similar considerations. Request all-files access An app can request all-files access from the user by doing the following Declare the MANAGE_EXTERNAL_STORAGE permission in the manifest. Use the ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION intent action to direct users to a system settings page where they can enable the following option for your app Allow access to manage all files. To determine whether your app has been granted the MANAGE_EXTERNAL_STORAGE permission, call Operations permitted by MANAGE_EXTERNAL_STORAGE The MANAGE_EXTERNAL_STORAGE permission grants the following Read and write access to all files within shared storage. Access to the contents of the table. Access to the root directory of both the USB on-the-go OTG drive and the SD card. Write access to all internal storage directoriesâ except /Android/data/, /sdcard/Android, and most subdirectories of /sdcard/Android. This write access includes direct file path access. Apps that are granted this permission still can't access the app-specific directories that belong to other apps, because these directories appear as subdirectories of Android/data/ on a storage volume. When an app has the MANAGE_EXTERNAL_STORAGE permission, it can access these additional files and directories using either the MediaStore API or direct file paths. When you use the Storage Access Framework, however, you can only access a file or directory if you can do so without having the MANAGE_EXTERNAL_STORAGE permission. Invoke another app's storage management activity On Android 12 API level 31 and higher, apps that have both the MANAGE_EXTERNAL_STORAGE permission and the QUERY_ALL_PACKAGES permissionâsuch as file management appsâcan use the getManageSpaceActivityIntent to send users to another app's custom space management activity. The getManageSpaceActivityIntent method takes in a package name and a request code, and it returns one of the following A PendingIntent, if the app with the specified package name has defined a custom "manage space" activity. The file management app that called the getManageSpaceActivityIntent method can then invoke the returned intent to send users to the custom activity. null, if the app with the specified package name doesn't define a "manage space" activity. Enable MANAGE_EXTERNAL_STORAGE for testing To explore how the MANAGE_EXTERNAL_STORAGE permission affects your app, you can enable the permission for testing. To do so, run the following command on the machine that's connected to your test device adb shell appops set -uid PACKAGE_NAME MANAGE_EXTERNAL_STORAGE allow Google Play notice This section provides a notice for developers who publish apps on Google Play. To limit broad access to shared storage, the Google Play store has updated its policy to evaluate apps that target Android 11 API level 30 or higher and request all-files access through the MANAGE_EXTERNAL_STORAGE permission. This policy is in effect as of May 2021. When your app targets Android 11 or higher and it declares the MANAGE_EXTERNAL_STORAGE permission, Android Studio shows the lint warning that appears in figure 1. This warning reminds you that the Google Play store has a policy that limits usage of the permission. Figure 1. Lint warning in Android Studio that reminds developers about the Google Play policy regarding the MANAGE_EXTERNAL_STORAGE permission. Request the MANAGE_EXTERNAL_STORAGE permission only when your app can't effectively make use of the more privacy-friendly APIs, such as the Storage Access Framework or the Media Store API. Your app's usage of the permission must fall within permitted uses and must be directly tied to the core functionality of the app. If your app includes a use case similar to any of the following, it's likely that it can request the MANAGE_EXTERNAL_STORAGE permission File managers Backup and restore apps Anti-virus apps Document management apps On-device file search Disk and file encryption Device-to-device data migration

1 How to check/change file system of my android phone and my sdcard from android? my phone is galaxy s4 and its not rooted. This is basic information that I expect to have every self respecting OS, what do you think ? Also how can I format my sd card to exfat which is faster as I heard ? 2 Is there a built in file manager on the S4? Not sure what it may be called...perhaps "My Files"? Or you can use an app to view files/folders on your device such as ES File Manager or Explorer, among others As far as formatting your sd card, you can use this program to format it Just remember you will lose anything on the card when formatting, so save what you need if you knew that already, sorry... And I don't know about it running faster when you format it to exfat, but perhaps others might. 3 I have ES file explorer and I dont see where to check what is my file system fat32, exfat , ntfs, ext3 ... 4 File Explorer aka FX gives filesystem types. All partitions on internal storage will be ext4. Only removable storage will be FAT32, exfat, etc. To run fsck to check ext4 filesystem integrity you must have root access. Not to worry, you should never need to run fsck. 5 Ah, I misunderstood you then, sorry You wish to know what your file system is formatted at? Edit thanks Crash...that's what I get for sending a reply this late and not refreshing the page first 6 CrashDamage - File Explorer aka FX does NOT show what is type of file system of my phone or my sd card never saw ntfs fat32 or ext3 4 or so on !!! I am still wondering how the hell I can check so basic thing about my phone .... If somebody know how to check the file system please help meI have no adapters cardreaders and so on I want to check it from my phone ! 7 Of course FX will show filesystem types. Long-press > Details. You might find another free utility, System Panel, easier to use for this and it provides lotsa other useful info.
