FileNotFoundException:EACCES (Permission denied)

Question

I get data from my service :

        JSONObject userGuid = new JSONObject();
        userGuid.put("userGuid", id);
        Bitmap bitmap = null;
        String response = HttpUtil.post(mService + "GetUser", userGuid.toString(), mCookie);

        JSONObject result = new JSONObject(response).getJSONObject("User");
        String temp = result.getJSONArray("UserImage").toString();

in received data, there is an Base64 image user and I got it and convert it to arryByte and then I convert it to InputStream :

        byte[] tmp = Base64.decode(temp, Base64.DEFAULT);
        InputStream is = new ByteArrayInputStream(tmp);

I want to write it to a File by outputStream :

OutputStream os = new FileOutputStream(f);

but I got this error:

java.io.FileNotFoundException: /storage/emulated/0/fcImages/581864034: open failed: EACCES (Permission denied)

In manifest I added these permissions:

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

What is your Idea?

Edit I create file in this way:

public class FileCache {

private File cacheDir;

public FileCache(Context context) {

    if((Environment
            .getExternalStorageState()).equals(Environment.MEDIA_MOUNTED)) {
            cacheDir = new File(Environment.getExternalStorageDirectory(), "fcImages");
    } else {
        cacheDir = context.getCacheDir();
    }
    if(!cacheDir.mkdirs()) {
        cacheDir.mkdirs();
    }
}

public File getFile(String id) {
    String filename = String.valueOf(id.hashCode());
    File f = new File(cacheDir, filename);
    return f;
}

Probably you need to read this. You must ask for permission in your code before trying to "use" it :) . https://developer.android.com/training/permissions/requesting.html — Andrei Terecoasa, Aug 28 '17 at 10:43
the same code is correct in this api but only difference is the other project I used a uri to get images and then write it:`URL imageUrl = new URL(url); HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection(); conn.setConnectTimeout(30000); conn.setReadTimeout(30000); conn.setInstanceFollowRedirects(true); InputStream is = conn.getInputStream(); OutputStream os = new FileOutputStream(f);` — sayres, Aug 28 '17 at 10:44
Just check permissions of your application in your device settings. Android api 23 and newest are ignoring your manifest permissions. Now it requires user-interaction to allow it. Check this [link](https://developer.android.com/training/permissions/requesting.html) — grabarz121, Aug 28 '17 at 11:11
@grabarz121 I create this file in the recyclerView Adapter. is correct? — sayres, Aug 28 '17 at 11:22

There are 3 things that come in my mind to check:

uses-permission tag is inside manifest tag (and not application tag)
EACCESS may due to the fact that fcImages directory does not exist, or it is a file
permission for Android api 23 must be requested runtime

uses permission is out side of my manifest: ` ` – sayres Aug 28 '17 at 10:48
I don't understand if you solved your issue or not. I'm quite confident about the second reasons (a permission will throw a Permission Error) – Matteo Ragni Aug 28 '17 at 10:56
I have a problem . I saw `fcImages` file is created – sayres Aug 28 '17 at 10:59
the same EACCESS is raised when you try to create a file inside another file. `fcImages` must be a directory – Matteo Ragni Aug 28 '17 at 11:00
permission for Android api 23 must be requested runtime was correct. – sayres Aug 28 '17 at 12:26
Thank you. I will upvote andrei-terecoasa and grabarz121 comments, because it was their suggestion – Matteo Ragni Aug 28 '17 at 13:16

If you're writing the file to the application's internal storage. Try this:

Example 1:

java.io.File xmlFile = new java.io.File((getActivity()
      .getApplicationContext().getFileStreamPath("FileName.xml")
      .getPath()));

Also give the manifest permission correct way as below:

Example 2 :

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