Android 6.0 Open Failed: Eacces (Permission Denied)

Android 6.0 open failed: EACCES (Permission denied)

Android added new permission model for Android 6.0 (Marshmallow).

So you have to check Runtime Permission :

What Are Runtime Permissions?

With Android 6.0 Marshmallow, Google introduced a new permission model that allows users to better understand why an application may be requesting specific permissions. Rather than the user blindly accepting all permissions at install time, the user is now prompted to accept permissions as they become necessary during application use.

When to Implement the New Model?

it doesn’t require full support until you choose to target version 23 in your application. 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.

This information is taken from here :

open failed: EACCES (Permission denied) on first run

There is a bug on Android 6.0, the permissions are not being applied until all the application processes are killed. In other versions of the operating system when there is a change in the permissions settings, the App is Killed automatically and restarted from last Activity.

I avoid the bug using this on onRequestPermissionsResult and Restart the App.

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (grantResults.length == permissions.length){
        if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.M) {
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage(R.string.restart_message)
                    .setPositiveButton(R.string.restart_button, (dialog, id) -> {
                        restartApp();
                    });
            builder.create().show();
        }
    }
}

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

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.

You are trying to write a file on a micro SD card. But they are read only for apps nowadays. Only a system camera app could have permission to write in the DCIM folder on SD.

Have a look at the second item returned by getExternalFilesDirs(). Your app can write in that app specific directory on SD card.

open failed: EACCES (Permission denied) in marshmallow while upload image to server

AndroidManifest.xml

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

IN Activity

  private static final int REQUEST_STORAGE = 112;

  if (Build.VERSION.SDK_INT >= 23) {
    String[] PERMISSIONS = {android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE};
    if (!hasPermissions(mContext, PERMISSIONS)) {
        ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST_STORAGE );
    } else {
        Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(i, PICK_IMAGE_REQUEST);
    }
} else {
    Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(i, PICK_IMAGE_REQUEST);
}

 /*get Permissions Result*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case REQUEST_STORAGE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

               Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
               startActivityForResult(i, PICK_IMAGE_REQUEST);
            } else {
                Toast.makeText(mContext, "The app was not allowed to write to your storage.", Toast.LENGTH_LONG).show();
            }
        }
    }
}

   /*check permissions  for marshmallow*/

private static boolean hasPermissions(Context context, String... permissions) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

Still gets the error open failed: EACCES (Permission denied)

I haven't really seen rules_version line in Firebase Storage but these default rules work in rules playground so there must be something wrong on client side.

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if true;
    }
  }
}

Can you try wrapping your code in a try-catch? That might help getting some additional debugging details such as path you are trying to access.

try {
  const pngRef = storage().ref("avatar/upload.png");
  console.log(“pngRef”, pngRef);
  await pngRef.putFile(fileUri);
  const url = await storage()
    .ref("avatar/upload.png")
    .getDownloadURL();
console.log(“url”, url);
} catch (e) {
  console.log(e)
  // This should contain additional details
}

Also please try adding the ref path in quotes as I've done above. Additionally, (likely not the issue) but make sure the code is in an async function. If it's still not fixed, please add the additional details from console in your question.

Error while reading text file on Android, open failed: EACCES (Permission denied)

Are u using Android Q ?
If that is the case you need to add this attribute in your AndroidManifest file :

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