Android writing file issue while setting song as Ringtone

Android writing file issue while setting song as Ringtone - android

I have successfully written a program to set song as Ringtone, but facing a very small issue
When i do tap on Button first time to set song as ringtone, getting this:
But when I do click on button again (second time), getting this:
So What could be the reason ? Why i never get success in first time...
Here is the complete code of RingtoneActivity.java:
public class RingtoneActivity extends Activity {
private final Context context = this;
private static final String TAG = "Meri Desi Look";
private File sound;
private final File folder = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_RINGTONES);
private MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button buttonRingtone = (Button) findViewById(R.id.btnRingtone);
buttonRingtone.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ask();
}
});
}
private void ask() {
mediaPlayer = MediaPlayer.create(this, R.raw.meri_desi_look);
mediaPlayer.start();
AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setTitle("Meri Desi Look");
alert.setMessage("You want this sound as your ringtone?");
alert.setCancelable(false);
alert.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int whichButton) {
mediaPlayer.stop();
mediaPlayer.reset();
confirmed();
dialog.dismiss();
}
});
alert.setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int whichButton) {
mediaPlayer.stop();
mediaPlayer.reset();
dialog.dismiss();
}
});
alert.show();
}
/**
* When the user confirms the popup, this will run, saving the file and
* setting the ringtone utilising the RingtoneManager class.
*/
private void confirmed() {
Boolean success = false;
sound = new File(folder, "meri_desi_look.mp3");
if (!sound.exists()) {
Log.i(TAG, "Writing Meri Desi Look to " + folder.toString());
try {
InputStream in = getResources().openRawResource(R.raw.meri_desi_look);
FileOutputStream out = new FileOutputStream(sound.getPath());
byte[] buff = new byte[1024];
int read = 0;
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
} finally {
in.close();
out.close();
}
} catch (Exception e) {
success = false;
Log.i(TAG, "Desi Look failed to write.");
}
} else {

Log.i(TAG, "Meri Desi Look ringtone already there.");
}
if (!success) {
onSetRingtoneError("We couldn't give you a Meri Desi Look ringtone.\n\nThere's an issue writing the file.");
} else {

}

values.put(MediaStore.Audio.Media.IS_MUSIC, true);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(sound.getAbsolutePath());
getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + sound.getAbsolutePath() + "\"",
null);
Uri newUri = getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, newUri);
onSetRingtoneSuccess();
} catch (Exception e) {
onSetRingtoneError("We couldn't give you a Meri Desi Look ringtone.\n\nThere's an issue setting the file.");
}
}
/**

private void onSetRingtoneError(String message) {

alert.setMessage(message);

}
#Override

mediaPlayer.release();
}
super.onPause();
}
}

I think you must have figured out long ago where the issue is in the code. But if you didn't,try the following.
private void confirmed() {
...
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
success = true;
}
catch(Exception e) {
success = false;
e.printStackTrace();
}
finally {
n.close();
out.close();
}
...
}

Class Context from other class android

I have two Classes (MainActivity & Dialogs)
I am trying to call the Dialogs Class (which as a context) to the MainAcitivity;
I have tried
Dialogs WorkOnDialog = (Dialogs)context;
WorkOnDialog.WorkOnSavedDialog();
This is my MainAcitivty
public class MainActivity extends AppCompatActivity {
Context context = this;
boolean WorkOn = false;
boolean WorkOff = false;
Dialogs WorkOnSaveDialog;
// Dialogs WorkOnSaveDialog = (Dialogs) context;
// Dialogs WorkOffSaveDialog = (Dialogs)context;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
//Press Work On Button
public void WorkOnClicked(View v) {
//Creates ImageButton var for ActionListener
ImageButton WorkOnClicked = (ImageButton) findViewById(R.id.WorkOn);
WorkOnClicked.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Gets & Sets Date, Filename, Data Content
// Creates Output Stream to save to file
String nowDate = DateFormat.getDateTimeInstance().format(new Date());
String filename = "WorkOnFile";
String string = nowDate + " Work On";
FileOutputStream outputStream;
File file = new File(Environment.getDataDirectory(), filename);
System.out.println("Work On Button CLicked");
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
System.out.println("!Wrote " + string + " !");
System.out.println("Wrote at " + file);
WorkOn = true;
} catch (Exception e) {
e.printStackTrace();
}
Dialogs WorkOnDialog = (Dialogs)context;
WorkOnDialog.WorkOnSavedDialog();
}
});
}
//Press WorkOff Button
public void WorkOffClicked(View v) {
//Creates ImageButton var for ActionListener
ImageButton WorkOffClicked = (ImageButton) findViewById(R.id.WorkOff);
WorkOffClicked.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Gets & Sets Date, Filename, Data Content
// Creates Output Stream to save to file
String nowDate = DateFormat.getDateTimeInstance().format(new Date());
String filename = "WorkOffFile";
String string = nowDate + " Work Off";
FileOutputStream outputStream;
File file = new File(Environment.getDataDirectory(), filename);
System.out.println(" Work Off Button CLicked");
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
System.out.println("!Wrote " + string + " !");
System.out.println("Wrote at " + file);
WorkOn=false;
} catch (Exception e) {
e.printStackTrace();
}
// WorkOffSaveDialog.WorkOffSavedDialog();
}
});
This is my Dialogs class
public class Dialogs extends AppCompatActivity {
public Context context = this;
public void WorkOnSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work On File Saved")
.setMessage("[Displaying for Test] Work On File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
public void WorkOffSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work Off File Saved")
.setMessage("[Displaying for Test] Work Off File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
}
Can anyone explain to me why I am unable to call this "Dialogs" Class within the main method?
I have searched about calling methods with context, and everything I found did not work out, what exactly is going wrong and why?

You need to make constructor to your Dialog class and pass the MainActivity context to this constructor :
public class Dialogs extends AppCompatActivity {
public Context context;
public Dialogs(Context context) {
this.context = context;
}
public void WorkOnSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work On File Saved")
.setMessage("[Displaying for Test] Work On File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
public void WorkOffSavedDialog() {
new AlertDialog.Builder(context)
.setTitle("Work Off File Saved")
.setMessage("[Displaying for Test] Work Off File Saved")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
}
}

knowing the url of the sound, you need to do the following:
resolve the URL in order to get the soundcloud API URL using Resolve endpoint
load the tracks API URL to get track representation in json or xml
initialise audio object and set the audio source to the value of stream_url property of track representation
The particular implementation varies depending on the libraries you use etc. But you'll definitely need to use HTTP requests, JSON parser and an audio object.

How I get the default ringtone list in android on programmatically?

I am android developer and want to create a android apps.In this apps ,it needed to show the android default ringtone list.But i can not show it.How to get the android default ringtone list .
Please help to me.

I have upvote Yuichi's answer but it did not completely work for me. For each ringtone I was getting same URI (different title thought). Following code worked for me -
public void listRingtones() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_RINGTONE);
Cursor cursor = manager.getCursor();
while (cursor.moveToNext()) {
String title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
Uri ringtoneURI = manager.getRingtoneUri(cursor.getPosition());
// Do something with the title and the URI of ringtone
}
}
You can see the working app on playstore.

This question/answer should provide what you're after: How to bring up list of available notification sounds on Android
You'll just need to swap out the RingtoneManager.TYPE_NOTIFICATION for RingtoneManager.TYPE_RINGTONE

You can get the list of Ringtones using RingtoneManager
public void listRingtones() {
RingtoneManager manager = new RingtoneManager(this);
manager.setType(RingtoneManager.TYPE_RINGTONE);
Cursor cursor = manager.getCursor();
while (cursor.moveToNext()) {
String title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
String uri = cursor.getString(RingtoneManager.URI_COLUMN_INDEX);
// Do something with the title and the URI of ringtone
}
}

Get a List of All ringTones with default ringtones in a list :
public static Map<String, Uri> getRingtones(Activity activity) {
RingtoneManager manager = new RingtoneManager(activity);
manager.setType(RingtoneManager.TYPE_RINGTONE);
Cursor cursor = manager.getCursor();
Map<String, Uri> list = new LinkedHashMap<>();
String title = "Set to Default";
Uri defaultRingtoneUri = RingtoneManager.getActualDefaultRingtoneUri(activity, RingtoneManager.TYPE_RINGTONE);
list.put(title, defaultRingtoneUri); // first add the default, to get back if select another
while (cursor.moveToNext()) {
String notificationTitle = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX);
Uri notificationUri = manager.getRingtoneUri(cursor.getPosition());
list.put(notificationTitle, notificationUri);
}
return list;
}
Then Create a dialog for select :
public static void getRingtonesDialog(Activity activity, Collection<String> items, int selected, DialogInterface.OnClickListener itemClickListener, DialogInterface.OnClickListener okClickListener, final DialogInterface.OnClickListener cancelClickListener) {
AlertDialog.Builder builderSingle = new AlertDialog.Builder(activity);
builderSingle.setTitle("Select Ringtone");
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(activity, android.R.layout.select_dialog_singlechoice);
arrayAdapter.addAll(items);
builderSingle.setNegativeButton(android.R.string.cancel, cancelClickListener);
builderSingle.setPositiveButton(android.R.string.ok, okClickListener);
builderSingle.setSingleChoiceItems(arrayAdapter, selected, itemClickListener);
builderSingle.setCancelable(false);
builderSingle.show();
}
Then Select And Play them to test : (Here AppSettings settings is SharedPreferences in your App ) :
Map<String, Uri> mRingtonesMap;
private Uri mLastSelectedRingtone = null;
private String mLastSelectedRingtoneName = "Default";
private MediaPlayer mMediaPlayer;
AppSettings settings;
TextView mRingtone ;
in Oncreate :
mRingtone = (TextView)findViewById(R.id.mRingtone);
settings = AppSettings.getInstance(this);
mRingtone.setText(getString(R.string.set_alarm_select_ringtone,
settings.getString(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName)));
mRingtone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
setupRingtoneSelection();
}
});
Then :
private void setupRingtoneSelection() {
mRingtonesMap = AlarmUtils.getRingtones(SelectionsActivity.this);
mRingtone.setText(getString(R.string.set_alarm_select_ringtone,
settings.getString(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName)));
mRingtone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final List<String> ringtoneKeys = new ArrayList<>(mRingtonesMap.keySet());
String ringtoneUri = settings.getString(AppSettings.Key.SELECTED_RINGTONE, "");
int selected = -1;
for (int i = 0; i < ringtoneKeys.size(); i++) {
String ring = ringtoneKeys.get(i);
if (mRingtonesMap.get(ring).toString().equalsIgnoreCase(ringtoneUri)) {
selected = i;
break;
}
}
AlarmUtils.getRingtonesDialog(SelectionsActivity.this, ringtoneKeys, selected, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) { //item selected
String name = ringtoneKeys.get(which);
mLastSelectedRingtoneName = name;
mLastSelectedRingtone = mRingtonesMap.get(name);
try {
if (mMediaPlayer == null) {
mMediaPlayer = new MediaPlayer();
} else {
mMediaPlayer.stop();
mMediaPlayer.reset();
}
mMediaPlayer.setDataSource(SelectionsActivity.this, mLastSelectedRingtone);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setLooping(false);
mMediaPlayer.prepare();
mMediaPlayer.start();
} catch (IOException ioe) {
//do nothing
}
}
}, new DialogInterface.OnClickListener() { //ok
#Override
public void onClick(DialogInterface dialog, int which) {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
settings.set(AppSettings.Key.SELECTED_RINGTONE, mLastSelectedRingtone.toString());
settings.set(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName);
//Update the textview
mRingtone.setText(getString(R.string.set_alarm_select_ringtone,
settings.getString(AppSettings.Key.SELECTED_RINGTONE_NAME, mLastSelectedRingtoneName)));
dialog.dismiss();
}
}, new DialogInterface.OnClickListener() { //cancel
#Override
public void onClick(DialogInterface dialog, int which) {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
}
dialog.dismiss();
}
});
}
});
}
#Override
protected void onDestroy() {
if (mMediaPlayer != null) {
if (mMediaPlayer.isPlaying()) {
mMediaPlayer.stop();
}
mMediaPlayer.release();
mMediaPlayer = null;
}
mRingtone.setOnClickListener(null);
super.onDestroy();
}
You can set and change ringtone, and after you want, can get back to default.

simplymoody, do what Chirag Raval suggested by declaring private static TextView homeText1, globally and in your onCreate initialise them. However, you should always update the UI from the main thread. But showDisclaimer() is still running on the background thread, so you could run the showDisclaimer() a couple of different ways. One would be to do what you have done in getUploadDate():
runOnUiThread(new Runnable() {
public void run() {
showDisclaimer()
}
});
Or you could use a handler:
private Handler showDisclaimerHandler = new Handler(new Handler.Callback() {
#Override
public boolean handleMessage(Message msg) {
homeText3x.setText("TEXT");
homeText1x.setVisibility(View.VISIBLE);
homeText2x.setVisibility(View.VISIBLE);
homeText3x.setVisibility(View.VISIBLE);
homeText4x.setVisibility(View.VISIBLE);
Log.d("ShowDisclaimer", "finished showing disclaimer");
return false;
}
});
And everywhere in a background thread you wish to run your showDisclaimer(), instead you run:
showDisclaimerHandler.sendEmptyMessage(0);
