Unable to navigate higher than root directory of internal storage

[noel105]

This issue exists on my Moto X Play running Android 6.0, specifically in the Snapprefs xposed module (http://forum.xda-developers.com/xposed/modules/app-snapprefs-ultimate-snapchat-utility-t2947254).

Clicking the "up" button while at the internal storage root directory does not advance any further up. I was attempting to access a folder on the SD card. Other apps have no issue reading, writing, or accessing the SD card, so I doubt the problem relates to read/write permissions.

The developer (MaaarZ) said he cannot fix it as the library isn't written by him and suggested I ask you.

Any help would be appreciated, thanks.

Just from the description I don't know why that would happen. This is the corresponding code, which is fairly defensive:

Android-DirectoryChooser/library/src/main/java/net/rdrei/android/dirchooser/DirectoryChooserFragment.java

Lines 190 to 200 in 488b559

	mBtnNavUp.setOnClickListener(new OnClickListener() {
	@Override
	public void onClick(final View v) {
	final File parent;
	if (mSelectedDir != null
	&& (parent = mSelectedDir.getParentFile()) != null) {
	changeDirectory(parent);
	}
	}
	});

I don't know why there wouldn't be a selected directory, so it's most likely that there is no parent available for the caller. I guess the developer of that extension would have to jump into the debugger to figure this one out.

Thanks, I'll let him know.

Worked for me:
When you use builder, add
builder.initialDirectory(android.os.Environment.getRootDirectory().toString());
