Is path exist

Checking for the existence of a path is one of the easiest tasks; you simply need to specify an incomplete path to the directory. Example of a correct path: /DCIM/Camera. Incorrect path: /storage/emulated/0/DCIM/Camera.

Simple:

Kotlin


fun isPathExist(ac: Activity, path: String): Boolean {
    val contentResolver: ContentResolver = ac.contentResolver
    val uri = Uri.parse("content://com.anready.croissant.files")
        .buildUpon()
        .appendQueryParameter("path", path)
        .appendQueryParameter("command", "pathExist")
        .build()

    var cursor: Cursor? = null
    try {
        cursor = contentResolver.query(uri, null, null, null, null)
        if (cursor != null && cursor.moveToFirst()) {
            val dataIndex = cursor.getColumnIndex("response")
            if (dataIndex == -1) {
                println("Data column not found")
                return false
            }

            val jsonArray = JSONArray(cursor.getString(dataIndex))
            if (error(jsonArray)) {
                println("Error: " + jsonArray.getJSONObject(0).getString("error"))
                return false
            }

            val fileInfo = jsonArray.getJSONObject(0)
            return fileInfo.getBoolean("result")
        } else {
            println("Error while getting data!")
        }
    } catch (e: Exception) {
        println("Error while getting data!\n" + e.message)
    } finally {
        cursor?.close()
    }
    return false
}

private fun error(jsonArray: JSONArray): Boolean {
    try {
        val error = jsonArray.getJSONObject(0)
        error.getString("error")
        return true
    } catch (e: JSONException) {
        return false
    }
}

By calling isPathExist(this, "/DCIM/Camera"): It will return true (directory exist), false (directory not exist), or ERR_01, view on page with errors
