I added this code and it's work fine, but getContentResolver().insert() return null
File directory = getExternalFilesDir(Environment.DIRECTORY_MUSIC);
values.put(MediaStore.Audio.AudioColumns.DATA, "${directory}${song?.title}");

File directory = getExternalFilesDir(Environment.DIRECTORY_MUSIC);

I had have read in the internet for answer for this problem but i've could't find something that could work.

This is because in Kotlin you have to specify the variable as nullable if it will be null in any case.
The error is in this function
var accessTokenTracker: AccessTokenTracker = object : AccessTokenTracker() {
override fun onCurrentAccessTokenChanged(
oldAccessToken: AccessToken,
currentAccessToken: AccessToken
) {
if (currentAccessToken == null) {
LoginManager.getInstance().logOut()
textView!!.text = ""
imageView!!.setImageResource(0)
}
}
}
here in the onCurrentAccessTokenChanged() function you are expecting the currentAccessToken to be null, but you have not made currentAccessToken as nullable hence it will fail and crash. Since only nullable elements can get null value assigned after initialisation in Kotlin. Therefore here you can make the variables as nullable and the problem will be solved.
You can make any variable as nullable like this
currentAccessToken : Type? , where the Type can be Int, String or any supported or custom type.
var accessTokenTracker: AccessTokenTracker = object : AccessTokenTracker() {
override fun onCurrentAccessTokenChanged(
oldAccessToken: AccessToken?,
currentAccessToken: AccessToken?
) {
if (currentAccessToken == null) {
LoginManager.getInstance().logOut()
textView!!.text = ""
imageView!!.setImageResource(0)
}
}
}
This will solve your problem.
It is always recommended that you make the variables as Nullable if you think that the variable might accommodate null at any time in the future in any case to avoid such crashes.

Getting list of device ringtones, weird error on 1 emulator?

I get the following error:
java.lang.IllegalArgumentException: Volume external_primary not found
But this only happens on 1 emulator I am running. It works fine on other emulators or my physical android phone.
Here is the code I am trying to run that causes the issue:
private fun listRingtones(): LinkedHashMap<String, String> {
var manager = RingtoneManager(this)
manager.setType(RingtoneManager.TYPE_NOTIFICATION)
var cursor: Cursor = manager.cursor
var list = LinkedHashMap<String, String>()
while (cursor.moveToNext()) {
var title: String = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX)
var ringtoneURI: Uri = manager.getRingtoneUri(cursor.position)
// Place the title and uri into a hashMap
list.put(title, ringtoneURI.toString())
}
return list
}
Specifically the debugger craps out on this line:
var cursor: Cursor = manager.cursor
Anyone seen anything like this or what could be the cause?
Here is the full error:

any one have any idea please ?

Your doInBackground() always returns an empty string, "". This empty string will be passed as the parameter to onPostExecute, which in turns uses this empty string as a parameter to handleJson. When you try to create a JSON array from this empty string it throws an exception at index 0, as it doesn't have any more data and it's not a valid json.
You need to return the result of the network call from doInBackground() instead of an empty string.

**
Use your code like this example below:
**
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val s = tvDisplay.text.toString()
btnOk.setOnClickListener {
Download().execute(s)
}
}
inner class Download : AsyncTask<String, Void, Void>() {
override fun doInBackground(vararg ss: String?): Void? {
validate(ss[0]!!)
return null
}
}
private fun validate(s:String) {
if(s.isNotEmpty()){
runOnUiThread {
Toast.makeText(this, "Working :)", Toast.LENGTH_SHORT).show()
}
}
else{
runOnUiThread {
Toast.makeText(this, "Not Working :(", Toast.LENGTH_SHORT).show()
}
}
}
}

Android Dropbox API v1 upload file and get shared link of this file

I have uploaded file and when I try to get the shared link then it gives NullPointerException.
FileInputStream fis = new FileInputStream(mFile);
String path = mPath + mFile.getName();
DropboxAPI.Entry response = mApi.putFile(path, fis,
mFile.length(), null, new ProgressListener() {
#Override
public long progressInterval() {
// Update the progress bar every half-second or so
return 500;
}
#Override
public void onProgress(long bytes, long total) {
publishProgress(bytes);
}
});
Log.i("DbExampleLog", "The uploaded file's rev is: " + response.rev);
if (response != null) {
mErrorMsg=response.path;
Log.e("DbExampleLog", "*****"+response.path+" The uploaded file's rev is: " + response.rev);
DropboxAPI.DropboxLink shareLink = mApi.share(response.path);
Log.e("DbExampleLog", "*****"+shareLink+" The uploaded file's rev is: " + response.rev);
if(shareLink!=null) {
if(shareLink.url!=null) {
Log.e("Null error URL*****",""+shareLink.url);
Log.e("Null error URL*****",""+getShareURL(shareLink.url));
String shareAddress = getShareURL(shareLink.url).toString();
Log.e("DbExampleLog", "URL -" + shareAddress + "*****" + response.path + " The uploaded file's rev is: " + response.rev);
}
else
Log.e("Null error URL*****",""+shareLink.url);
}
else{
Log.e("Null error*****",""+shareLink);
}
return true;
}
It returns like -

Please suggest me why this error occur, but yesterday using this code it worked.
UPDATE CODE ASKED BY Greg

String redirectedUrl = null;
