I'm making an app that uses Voice Recognition. And it works perfectly with Android KitKat 4.4.4 (API 19). But when I try it on Nouget 7.0 (API 24) or Lollipop voice recognition dialog box says Network not connected.
I have internet connection, and I have added permissions in Manifest. What might be the issue?
Here's my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.woop.loudness">
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".WebList" android:label="@string/app_name" />
<activity android:name=".AddWeb" android:label="@string/app_name" />
<!--<service android:enabled="true" android:name=".UartService" />-->
</application>
</manifest>

I have copied your code, you are getting an error, take debug off of the "Selected App"
Caused by: com.google.android.apps.gsa.shared.exception.GsaIOException: Error code: 393237 | Error code: 393222 | couldn't start recording, state is:1
This is because you are still recording/capturing data in your main activity without releasing the audio, I added it here and it works fine, but do not forget to restart it again
public void startVoiceRecognitionActivity() {
audio.stop();
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
"Kalbėkite");
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}
