BLE connected with Lollipop but not connected with Nougat

I'm new in android develop and I'm developing an app that transmit/receive data to a BLE module via Uart service.
With smartphone android 5.x.x the app works fine, it connects with the hardware and receive/transmit data.
With smartphone android 7.x.x the app doesn't connects.
Below you can see a snippet of MainActivity.java:
private final BroadcastReceiver UARTStatusChangeReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
final Intent mIntent = intent;
//*********************//
if (action.equals(UartService.ACTION_GATT_CONNECTED)) {
runOnUiThread(new Runnable() {
public void run() {
Log.d(TAG, "HW_CONNECT_MSG");
DisconnectButton.setEnabled(true);
DeviceInfo.setText("Device Information:");
DeviceName.setText(mDevice.getName() + " - Connected");
mState = UART_PROFILE_CONNECTED;
isConnected = true;
if(isConnected) {
//Serial protocol to send command on MCU
Connectcmd[0] = (byte) STX;
Connectcmd[1] = (byte) 0x02;
Connectcmd[2] = (byte) 0x43; // 'C';
Connectcmd[3] = (byte) 0x54; // 'T'
Connectcmd[4] = (byte) ETX;
try {
//send data to UART service
SendData(Connectcmd);
sleep(500); // wait 500ms to send data
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
new Handler().postDelayed(mUpdateTimeTask, 2000);
}
else
{
isConnected = false;
}
}
});
}
It's seem that when SendData, the GATT operation is not yet finished. Smartphone show the message "Device doesn't support UART over BLE. Disconnecting..." due to action.equals(UartService.DEVICE_DOES_NOT_SUPPORT_BLE_UART).
If I delete the if(isConnected)...else... statement also smartphone with android 7.x.x will connects.
My question is what's happen and how can I resolve this issue?
My goal is to send a command to hardware via BLE so when the mcu is connected, a buzzer make a sound.
Thanks for help….

How to record audio with Smart Eye Glass?

I am developing an audio recorder with Sony Smart Eyeglass, but it does not work well.
My application records just a voice from phone microphone, not from Smart Eyeglass microphone.
I'd like to record a voice just only from Smart Eyeglass microphone.
Any ideas?
Here is my code.

Some phones require an extra method call after setMode:
private AudioManager m_amAudioManager;
m_amAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
m_amAudioManager.setMode(AudioManager.MODE_IN_CALL);
m_amAudioManager.setSpeakerphoneOn(false);
To learn more about rest of the operation, there is a guide on Audio I/O with SmartEyeglass:
https://developer.sony.com/develop/wearables/smarteyeglass-sdk/guides/use-bluetooth-for-audio-io/

Would you put your recording code in the Activity and test without using the eyeglass first?
As you are using the phone's capability only, it should work if you can record from microphone in Activity alone. Please ensure you have added uses-permission tag in AndroidManifest.xml

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.
