4. TTS API DOC 

TTS API doc
Synthesizes speech from text for immediate playback or to create a sound file.
A TextToSpeech instance can only be used to synthesize text once it has completed its initialization.
Implement the TextToSpeech.OnInitListener to be notified of the completion of the initialization.
When you are done using the TextToSpeech instance,
call the shutdown() method to release the native resources used by the TextToSpeech engine.
Apps targeting Android 11 that use text-to-speech should declare TextToSpeech.Engine.INTENT_ACTION_TTS_SERVICE in the queries elements of their manifest:

java.net.SocketException: socket failed: EPERM (Operation not permitted) solved in one shot.

Image
Today, we will look at how to fix socket failed: EPERM (Operation not permitted) warning. The error above looks like a network socket error, but it actually has a different cause. In Android Studio, the INTERNET PERMISSION permission is granted and the app is run, but the above error continues to occur. Personally, I've been through this 3-4 times. In this case, do not shovel here and there, and delete the app currently being built from the terminal (emulator or mobile phone). After reinstalling, you can see that the issue is resolved neatly. The cause of the above error is after installing the app without giving internet permission in the android manifest file. Sometimes it happens when you put internet permission and rebuild. In other words, it is not a network error, so please simply reinstall it.   Have a nice day.   For reference, the following is a description of socket.   This class implements client sockets (also called just "sockets"). A socket is an endpoint for...

Open multiple Android Studio projects

Image
When developing Android, there are times when you need to open several projects at once and work on them. For example, in order to copy the features of the old project to the current project, it is very convenient to open two Android studios and work. However, the default setting of Android Studio is to open only one project. Because of this, if you try to open an old project, the current project will be closed. 1. Change set value    -. Open the Settings window by selecting the "File -> Settings" menu.       Select "Appearance & Behavior -> System Settings".      In the Project section on the right, under "Open project in" select "New window". 2. Behavior after change    -. After changing the settings as in number 1, you can open two Android studios at once as shown below. thank you
