I am getting above errors for version 2.0.4.2, I am getting errors frequently and too much in my crashlytics, but not getting in actual when I test it on any device, how can I fix these errors as it's full log shows error in only this library?

[codekidX]

1. You are setting theme but you are not setting scheme

2. line numbers are important for this, please paste full log

3. Which file?

4. Full log

5. Which android version this came for? full log

6. I think some user has a storage that is not supported by the statfs (example some chinese OEMs)

[ankitgupta199]

I am mentioning here full log of my code for setting scheme and theme for 1st question-
1-(a) I tried to set scheme this way, also mentioning second way below

`StorageChooser.Theme theme = new StorageChooser.Theme(getActivity());
int[] myScheme = theme.getDefaultScheme();
// this is overview dialog list color
myScheme[StorageChooser.Theme.OVERVIEW_HEADER_INDEX] = getActivity().getResources().getColor(R.color.colorAccent);
myScheme[StorageChooser.Theme.OVERVIEW_BG_INDEX] = getActivity().getResources().getColor(R.color.white);
myScheme[StorageChooser.Theme.OVERVIEW_INDICATOR_INDEX] = getActivity().getResources().getColor(R.color.c_252525);
myScheme[StorageChooser.Theme.OVERVIEW_STORAGE_TEXT_INDEX] = getActivity().getResources().getColor(R.color.c_252525);
myScheme[StorageChooser.Theme.OVERVIEW_TEXT_INDEX] = getActivity().getResources().getColor(R.color.white);
myScheme[StorageChooser.Theme.OVERVIEW_MEMORYBAR_INDEX] = getActivity().getResources().getColor(R.color.colorAccent);

    // this is secondary dialog list color
    myScheme[StorageChooser.Theme.SEC_BG_INDEX] = getActivity().getResources().getColor(R.color.white);
    myScheme[StorageChooser.Theme.SEC_FOLDER_TINT_INDEX] = getActivity().getResources().getColor(R.color.colorAccent);
    myScheme[StorageChooser.Theme.SEC_ADDRESS_BAR_BG] = getActivity().getResources().getColor(R.color.c_c5c5c5);
    myScheme[StorageChooser.Theme.SEC_ADDRESS_TINT_INDEX] = getActivity().getResources().getColor(R.color.c_252525);
    myScheme[StorageChooser.Theme.SEC_FOLDER_CREATION_BG_INDEX] = getActivity().getResources().getColor(R.color.c_da6c6c);
    myScheme[StorageChooser.Theme.SEC_DONE_FAB_INDEX] = getActivity().getResources().getColor(R.color.colorAccent);
    myScheme[StorageChooser.Theme.SEC_SELECT_LABEL_INDEX] = getActivity().getResources().getColor(R.color.colorAccent);
    myScheme[StorageChooser.Theme.SEC_HINT_TINT_INDEX] = getActivity().getResources().getColor(R.color.colorAccent);
    myScheme[StorageChooser.Theme.SEC_TEXT_INDEX] = getActivity().getResources().getColor(R.color.c_252525);

    theme.setScheme(myScheme);

`

1- (b)- Second way-

StorageChooser.Theme theme = new StorageChooser.Theme(getActivity()); theme.setScheme(getResources().getIntArray(R.array.paranoid_theme));

Set scheme in Theme

StorageChooser chooser = new StorageChooser.Builder() .withActivity(getActivity()) .withFragmentManager(getFragmentManager()) .allowCustomPath(true) .setType(StorageChooser.FILE_PICKER) .filter(StorageChooser.FileType.DOCS) .withMemoryBar(true) .setTheme(theme) .build(); chooser.show();

In both cases I got same logs, mentioning below crash logs-

[ankitgupta199]

@codekidX I had shared all logs, please check once and tell me about solutions.

[codekidX]

1st things 1st upgrade to 2.0.4.4. These logs are pretty weird I'll separately test them with your code and let you know.

[ankitgupta199]

Yes, I can upgrade in 2.0.4.4, but for that I have required to upgrade my all code in androidx, as I tried ,so I am doing that changes and that will take time to upgrade all code, but if possible then please tell me these logs solutions at least for 1 & 2 points, both logs are coming too frequently.

[ankitgupta199]

@codekidX- I upgragded library 2.0.4.4, but still getting crashes for above mentioned points, can you suggest me any solution.

[codekidX]

@ankitgupta199 will you be willing to give me a screen recording of how you get this error. It would be helpful to identify on which step you get this crashes (if you have encountered it yourself).

Btw if any of the old users who did not update might be crashes, are you sure the users upgraded your app?

[muzzikapp]

Fixed in my fork branch, basicly what i do is if i got an exception i set the selected folder to default music folder (at least app doesnt crash because of this)

https://github.com/muzzikapp/storage-chooser

[codekidX]

@muzzikapp thanks for this, I'll handle it in current branch and create a release.

[ankitgupta199]

@codekidX , I am not getting these crashes on my devices when I test it , but getting crash logs from crashlytics and firebase for others users who is using app, so I can provide you only these logs. Also I have upgraded this library for 2.0.4.4 and as per analytics I can track that 95% users upgraded app, and I am still getting same logs from upgraded users. Is there I need to make any change again in version or anywhere in library, please suggest me that?
