App file management¶

File path¶

As shown in the picture on the right, the corresponding file paths are displayed in sequence.

private val devicePath = listOf(
    appInternalFilesDir().path,
    appInternalCacheDir().path,
    appExternalFilesDir(null).path,
    appExternalCacheDir().path,
    ImageMgr.getExternalFilesDir().path,
    ImageMgr.getSharedFilesDir().path,
    MusicMgr.getExternalFilesDir().path,
    MusicMgr.getSharedFilesDir().path
)

@Composable
fun DevicePath(modifier: Modifier = Modifier){
    LazyColumn(modifier = modifier){
        items(devicePath){
            ListItem(
                headlineText = { 
                    Text(text = it) 
                }
            )
        }
    }
}
