Crash / Error - Could not generate container java.util.zip.ZipException: error in opening zip file and Failed to initialize book kotlin.KotlinNullPointerException
Steps to reproduce / Describe in detail -
My code for getting a file from the storage:
val fileName = bookPath.split("/") val file = requireActivity().getFileStreamPath(fileName[fileName.size - 1]) reader.openBook(file.absolutePath)
My code for write book in storage:
` try { val file = requireActivity().getFileStreamPath(book.name.replace(" ", "_") + ".epub") val writer = FileWriter(file)
GlobalScope.launch(Dispatchers.IO) {
val url = URL(book.fileUrl)
val reader = BufferedReader(InputStreamReader(url.openStream()))
var line = reader.readLine()
val result = StringBuilder()
while (line != null) {
result.append(reader.readLine())
writer.append(result.toString() + "\n")
line = reader.readLine()
}
Log.d("DownloadBookMy", "writeFile(): $result")
writer.flush()
} catch (e: IOException) {
showToast(getString(R.string.some_went_error, e.message))
e.printStackTrace()
} catch (e: Exception) {
showToast(getString(R.string.some_went_error, e.message))
e.printStackTrace()
}`
When I open a book, their storage gives me errors:
