(Android Studio Speech Recognizer) I'm getting

            Log.i("111111","11111111");
        }

}

And My Android Manifest File looks like:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="blessupboys.speechtest">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        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=".VoiceRecognitionTest"
            android:label="@string/title_activity_voice_recognition_test"
            android:theme="@style/AppTheme.NoActionBar"></activity>
    </application>

    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

</manifest>

My logs show that it stops because of error 9 generated in the onError() function.

I am trying to run this sample program to try to get familiar with the Speech Recognizer software..

Could this be an issue being caused by the fact that I'm running it on android studio rather than a real device? I am pretty stuck on this.

回答1:

In case anyone comes to this question and none of the other answers help, you might want to try requesting permissions using the following code:

private void requestRecordAudioPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        String requiredPermission = Manifest.permission.RECORD_AUDIO;

        // If the user previously denied this permission then show a message explaining why
        // this permission is needed
        if (checkCallingOrSelfPermission(requiredPermission) == PackageManager.PERMISSION_DENIED) {
            requestPermissions(new String[]{requiredPermission}, 101);
        }
    }
}

回答2:

It was just a problem with it not being supported on emulators. It works on a physical device.

回答3:

What I found is that if you are "just a physical device" and you still get the same error, that is most probably is because if the target SDK in the gradle file. you see in later versions they have changed the level of permission to dangers, so by downgrading it, then you it will work.

"I am not an expert in this, but this worked from me fine"

try these links for references to your project also check all android manifest permissions here and here is a sample project

hope these hints help to solve your problem!
