Exception 'open failed: EACCES (Permission denied)' on Android

I am getting

open failed: EACCES (Permission denied)

on the line OutputStream myOutput = new FileOutputStream(outFileName);

I checked the root, and I tried android.permission.WRITE_EXTERNAL_STORAGE.

How can I fix this problem?

try {
    InputStream myInput;

    myInput = getAssets().open("XXX.db");

    // Path to the just created empty db
    String outFileName = "/data/data/XX/databases/"
            + "XXX.db";

    // Open the empty db as the output stream
    OutputStream myOutput = new FileOutputStream(outFileName);

    // Transfer bytes from the inputfile to the outputfile
    byte[] buffer = new byte[1024];
    int length;
    while ((length = myInput.read(buffer)) > 0) {
        myOutput.write(buffer, 0, length);
    }

    // Close the streams
    myOutput.flush();
    myOutput.close();
    myInput.close();
    buffer = null;
    outFileName = null;
}
catch (IOException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}

For API 33+ you need to request this permission to read Images

<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />

    String[] permissionNew = new String[]{ Manifest.permission.READ_MEDIA_IMAGES};
    String[] permissions = new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};



private boolean checkPermissions() {
    int result;
    List<String> listPermissionsNeeded = new ArrayList<>();
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        for (String p : permissionsNew) {
            result = ContextCompat.checkSelfPermission(requireActivity(), p);
            if (result != PackageManager.PERMISSION_GRANTED) {
                listPermissionsNeeded.add(p);
            }
        }
    } else {
        for (String p : permissions) {
            result = ContextCompat.checkSelfPermission(requireActivity(), p);
            if (result != PackageManager.PERMISSION_GRANTED) {
                listPermissionsNeeded.add(p);
            }
        }
    }
    if (!listPermissionsNeeded.isEmpty()) {
        requestPermissions(listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), 200);
        return false;
    }
    return true;
}

If anyone is receiving this error using a hybrid app, using for example ionic, and the previous solutions did not work, first confirm that the path is valid.

If the error is coming from downloadFile or writeFile, confirm that there is not already a file in the location, it was my error.

The ionic standard library does not 'overwrite' and will throw an exception if the target file already exists, when trying to download or write. in this case the downloadFile itself tries to open and will throw EACCES exception

Solution:

If this is your problem you can save the file name with `_${Date.now()} at the end of the name or verify if the file exists and delete it before creating a new one.

I also faced this problem and solved the problem with this method

   suspend fun copyFileToInternalStorage(context: Context,uri: Uri, newDirName: String): String? {
    val returnCursor = context.contentResolver.query(
        uri, arrayOf(
            OpenableColumns.DISPLAY_NAME, OpenableColumns.SIZE
        ), null, null, null
    )


    /*
     * Get the column indexes of the data in the Cursor,
     *     * move to the first row in the Cursor, get the data,
     *     * and display it.
     * */
    val nameIndex = returnCursor!!.getColumnIndex(OpenableColumns.DISPLAY_NAME)
    val sizeIndex = returnCursor.getColumnIndex(OpenableColumns.SIZE)
    returnCursor.moveToFirst()
    val name = returnCursor.getString(nameIndex)
    val output: File = if (newDirName != "") {
        val dir =
            File(context.filesDir.toString() + "/" + newDirName)
        if (!dir.exists()) {
            dir.mkdir()
        }
        File(context.filesDir.toString() + "/" + newDirName + "/" + name)
    } else {
        File(context.filesDir.toString() + "/" + name)
    }
    try {
        val inputStream =
            context.contentResolver.openInputStream(uri)
        val outputStream = FileOutputStream(output)
        var read = 0
        val bufferSize = 1024
        val buffers = ByteArray(bufferSize)
        while (inputStream!!.read(buffers).also { read = it } != -1) {
            outputStream.write(buffers, 0, read)
        }
        inputStream.close()
        outputStream.close()
    } catch (e: java.lang.Exception) {
        Log.e("Exception", e.message!!)
    }
    return output.path

Are you getting this crash while running the junit4 test of Jetpack Macrobenchmark in a real device?

If yes then increase the version of androidx.profileinstaller:profileinstaller.

Just click this link, find stable version and add to build.gradle(app).

For example implement(androidx.profileinstaller:profileinstaller:1.3.0).

I found it here: https://issuetracker.google.com/issues/203598149

i faced the same error on xiaomi devices (android 10 ). The following code fixed my problem. Libraries: Dexter(https://github.com/Karumi/Dexter) and Image picker(https://github.com/Dhaval2404/ImagePicker)

Add manifest ( android:requestLegacyExternalStorage="true")

    public void showPickImageSheet(AddImageModel model) {
    BottomSheetHelper.showPickImageSheet(this, new BottomSheetHelper.PickImageDialogListener() {
        @Override
        public void onChooseFromGalleryClicked(Dialog dialog) {

            Dexter.withContext(OrderReviewActivity.this)                   .withPermissions(Manifest.permission.READ_EXTERNAL_STORAGE)
                    .withListener(new MultiplePermissionsListener() {
                        @Override
                        public void onPermissionsChecked(MultiplePermissionsReport report) {
                            if (report.areAllPermissionsGranted()) {
                                ImagePicker.with(OrderReviewActivity.this)

                            }

Google has a new feature on Android Q: filtered view for external storage. A quick fix for that is to add this code in the AndroidManifest.xml file:

<manifest ... >
    <!-- This attribute is "false" by default on apps targeting Android Q. -->
    <application android:requestLegacyExternalStorage="true" ... >
     ...
    </application>
</manifest>

You can read more about it here: https://developer.android.com/training/data-storage/use-cases

Edit: I am starting to get downvotes because this answer is out of date for Android 11. So whoever sees this answer please go to the link above and read the instructions.

I Use the below process to handle the case with android 11 and targetapi30

  1. As pre-created file dir as per scoped storage in my case in root dir files//<Image/Video... as per requirement>

  2. Copy picked file and copy the file in cache directory at the time of picking from my external storage

  3. Then at a time to upload ( on my send/upload button click) copy the file from cache dir to my scoped storage dir and then do my upload process

use this solution due to at time upload app in play store it generates warning for MANAGE_EXTERNAL_STORAGE permission and sometimes rejected from play store in my case.

Also as we used target API 30 so we can't share or forward file from our internal storage to app

Android 10 (API 29) introduces Scoped Storage. Changing your manifest to request legacy storage is not a long-term solution.

I fixed the issue when I replaced my previous instances of Environment.getExternalStorageDirectory() (which is deprecated with API 29) with context.getExternalFilesDir(null).

Note that context.getExternalFilesDir(type) can return null if the storage location isn't available, so be sure to check that whenever you're checking if you have external permissions.

Strangely after putting a slash "/" before my newFile my problem was solved. I changed this:

File myFile= new File(Environment.getExternalStorageDirectory() + "newFile");

to this:

File myFile= new File(Environment.getExternalStorageDirectory() + "/newFile");

UPDATE: as mentioned in the comments, the right way to do this is:

File myFile= new File(Environment.getExternalStorageDirectory(), "newFile");

Be aware that the solution:

<application ...
    android:requestLegacyExternalStorage="true" ... >

Is temporary, sooner or later your app should be migrated to use Scoped Storage.

In Android 10, you can use the suggested solution to bypass the system restrictions, but in Android 11 (R) it is mandatory to use scoped storage, and your app might break if you kept using the old logic!

This video might be a good help.

To store a file in a directory which is foreign to the app's directory is restricted above API 29+. So to generate a new file or to create a new file use your application directory like this :-

So the correct approach is :-

val file = File(appContext.applicationInfo.dataDir + File.separator + "anyRandomFileName/")

You can write any data into this generated file !

The above file is accessible and would not throw any exception because it resides in your own developed app's directory.

The other option is android:requestLegacyExternalStorage="true" in manifest application tag as suggested by Uriel but its not a permanent solution !

Add android:requestLegacyExternalStorage="true" to the Android Manifest It's worked with Android 10 (Q) at SDK 29+
or After migrating Android X.

 <application
    android:name=".MyApplication"
    android:allowBackup="true"
    android:hardwareAccelerated="true"
    android:icon=""
    android:label=""
    android:largeHeap="true"
    android:supportsRtl=""
    android:theme=""
    android:requestLegacyExternalStorage="true">

In my case the error was appearing on the line

      target.createNewFile();

since I could not create a new file on the sd card,so I had to use the DocumentFile approach.

      documentFile.createFile(mime, target.getName());

For the above question the problem may be solved with this approach,

    fos=context.getContentResolver().openOutputStream(documentFile.getUri());

See this thread too, How to use the new SD card access API presented for Android 5.0 (Lollipop)?

keep in mind that even if you set all the correct permissions in the manifest: The only place 3rd party apps are allowed to write on your external card are "their own directories" (i.e. /sdcard/Android/data/) trying to write to anywhere else: you will get exception: EACCES (Permission denied)

            public void run() {


                checkMermission();
            }
        }, 4000);
    }

    private void checkMermission(){
        Dexter.withActivity(this)
                .withPermissions(
                        android.Manifest.permission.READ_EXTERNAL_STORAGE,
                        android.Manifest.permission.WRITE_EXTERNAL_STORAGE,

In my case I was using a file picker library which returned the path to external storage but it started from /root/. And even with the WRITE_EXTERNAL_STORAGE permission granted at runtime I still got error EACCES (Permission denied).
So use Environment.getExternalStorageDirectory() to get the correct path to external storage.

Example:
Cannot write: /root/storage/emulated/0/newfile.txt
Can write: /storage/emulated/0/newfile.txt

boolean externalStorageWritable = isExternalStorageWritable();
File file = new File(filePath);
boolean canWrite = file.canWrite();
boolean isFile = file.isFile();
long usableSpace = file.getUsableSpace();

Log.d(TAG, "externalStorageWritable: " + externalStorageWritable);
Log.d(TAG, "filePath: " + filePath);
Log.d(TAG, "canWrite: " + canWrite);
Log.d(TAG, "isFile: " + isFile);
Log.d(TAG, "usableSpace: " + usableSpace);

/* Checks if external storage is available for read and write */
public boolean isExternalStorageWritable() {
    String state = Environment.getExternalStorageState();
    if (Environment.MEDIA_MOUNTED.equals(state)) {
        return true;
    }
    return false;
}

Output 1:

externalStorageWritable: true
filePath: /root/storage/emulated/0/newfile.txt
isFile: false
usableSpace: 0

Output 2:

externalStorageWritable: true
filePath: /storage/emulated/0/newfile.txt
isFile: true
usableSpace: 1331007488

I had the same problem (API >= 23).

The solution https://stackoverflow.com/a/13569364/1729501 worked for me, but it was not practical to disconnect app for debugging.

my solution was to install proper adb device driver on Windows. The google USB driver did not work for my device.

STEP 1: Download adb drivers for your device brand.

STEP 2: Go to device manager -> other devices -> look for entries with word "adb" -> select Update driver -> give location in step 1

Maybe the answer is this:

on the API >= 23 devices, if you install app (the app is not system app), you should check the storage permission in "Setting - applications", there is permission list for every app, you should check it on! try

My issue was with "TargetApi(23)" which is needed if your minSdkVersion is bellow 23.

So, I have request permission with the following snippet

protected boolean shouldAskPermissions() {
    return (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1);
}

@TargetApi(23)
protected void askPermissions() {
    String[] permissions = {
            "android.permission.READ_EXTERNAL_STORAGE",
            "android.permission.WRITE_EXTERNAL_STORAGE"
    };
    int requestCode = 200;
    requestPermissions(permissions, requestCode);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
// ...
    if (shouldAskPermissions()) {
        askPermissions();
    }
}

For API 23+ you need to request the read/write permissions even if they are already in your manifest.

// Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
};

/**
 * Checks if the app has permission to write to device storage
 *
 * If the app does not has permission then the user will be prompted to grant permissions
 *
 * @param activity
 */
public static void verifyStoragePermissions(Activity activity) {
    // Check if we have write permission
    int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        // We don't have permission so prompt the user
        ActivityCompat.requestPermissions(
                activity,
                PERMISSIONS_STORAGE,
                REQUEST_EXTERNAL_STORAGE
        );
    }
}

AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I had the same problem... The <uses-permission was in the wrong place. This is right:

 <manifest>
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        ...
        <application>
            ...
            <activity> 
                ...
            </activity>
        </application>
    </manifest> 

The uses-permission tag needs to be outside the application tag.

In addition to all answers, if the clients are using Android 6.0, Android added new permission model for (Marshmallow).

Trick: If you are targeting version 22 or below, your application will request all permissions at install time just as it would on any device running an OS below Marshmallow. If you are trying on the emulator then from android 6.0 onwards you need to explicitly go the settings->apps-> YOURAPP -> permissions and change the permission if you have given any.

I had the same error when was trying to write an image in DCIM/camera folder on Galaxy S5 (android 6.0.1) and I figured out that only this folder is restricted. I simply could write into DCIM/any folder but not in camera. This should be brand based restriction/customization.

Change a permission property in your /system/etc/permission/platform.xml
and group need to mentioned as like below.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE">
