问题：

广播接收器组件不允许绑定服务。如何从广播接收器启动文本到语音转换？

我的应用程序给出了一个错误，即不允许BroadcastReceiver组件绑定到服务。当短信到达时，我正在呼叫广播接收器，文本将转换为语音。我的接受者正确地呼叫。

但我的代码给出的错误如下

致命html" target="_blank">异常：主进程：texttospeech。tts。通用域名格式。tts，PID:12811 java。lang.RuntimeException：无法启动接收器texttospeech。tts。通用域名格式。tts。ttsBroadcast：android。所容纳之物ReceiverCallNotAllowedException：不允许BroadcastReceiver组件绑定到android上的服务。应用程序。ActivityThread。android上的HandlerReceiver（ActivityThread.java:2618）。应用程序。ActivityThread。在android上访问1700美元（ActivityThread.java:148）。应用程序。android上的ActivityThread$H.handleMessage（ActivityThread.java:1369）。操作系统。处理程序。android上的dispatchMessage（Handler.java:102）。操作系统。活套。android上的loop（Looper.java:135）。应用程序。ActivityThread。java上的main（ActivityThread.java:5312）。lang.reflect。方法在java中调用（本机方法）。lang.reflect。方法在com上调用（方法java:372）。Android内部的操作系统。ZygoteInit$MethodandArgscaler。在com上运行（ZygoteInit.java:901）。Android内部的操作系统。合子岩。main（ZygoteInit.java:696）由：android引起。所容纳之物ReceiverCallNotAllowedException：不允许BroadcastReceiver组件绑定到android上的服务。应用程序。ReceiverRestrictedContext。android上的bindService（ContextImpl.java:215）。演讲tts。TextToSpeech。android上的connectToEngine（TextToSpeech.java:800）。演讲tts。TextToSpeech。android上的initTts（TextToSpeech.java:770）。演讲tts。TextToSpeech。（TextToSpeech.java:723）在android上。演讲tts。TextToSpeech。（TextToSpeech.java:702）在android上。演讲tts。TextToSpeech。（TextToSpeech.java:686）位于TextToSpeech。tts。通用域名格式。tts。ttsBroadcast。android上的onReceive（ttsBroadcast.java:23）。应用程序。ActivityThread。HandlerReceiver（ActivityThread.java:2611）

这是我的密码

ttsBroadcast。Java语言

public class ttsBroadcast extends BroadcastReceiver implements TextToSpeech.OnInitListener {
    private TextToSpeech tts;
    private String msg;
    @Override
    public void onReceive(Context context, Intent intent) {


        Toast.makeText(context,"sms recived",Toast.LENGTH_LONG).show();

        tts = new TextToSpeech(context,this);
        tts.speak(msg,TextToSpeech.QUEUE_FLUSH,null);


    }

    @Override
    public void onInit(int i) {

        tts.setLanguage(Locale.ENGLISH);
    }

}

由于这个问题似乎仍然存在，我将添加一些行。首先，我认为您应该有一个服务，并从BroadcastReceiver调用此服务。这可能是一种可能的实现。

广播接收器：

public class ReadMessageBroadcastReceiver extends BroadcastReceiver {

public final static String TAG = "ReadMessageBroadcastReceiver";

public ReadMessageBroadcastReceiver() {
}

@Override
public void onReceive(Context context, Intent intent) {
    if(intent.getAction().equals(Actions.ACTION_TTS_READ_MESSAGE)) {
        Log.v(TAG, "Read messages on tts received trough notification");
        String[] unreadMessages = intent.getStringArrayExtra(Constants.EXTRA_UNREAD_MESSAGES);
        if (unreadMessages != null) {
            Log.v(TAG, "Read messages on tts trough notification received " + unreadMessages.length
                    + " total messages");
            String messageNumber = context.getString(R.string.notification_message_number);

            ArrayList<String> allMessagesToRead = new ArrayList<>(unreadMessages.length);
            for (int i = 0; i < unreadMessages.length; i++) {
                StringBuilder stringBuilder = new StringBuilder();
                stringBuilder.append(messageNumber);
                stringBuilder.append(" ");
                stringBuilder.append(i + 1);
                stringBuilder.append(" ");
                stringBuilder.append(unreadMessages[i]);
                stringBuilder.append(" ");
                allMessagesToRead.add(stringBuilder.toString());
            }

            Log.d(TAG, "Texts to read loud: " + allMessagesToRead);
            Intent speechIntent = new Intent(context, TextToSpeechService.class);
            speechIntent.putStringArrayListExtra(TextToSpeechService.TEXT_TO_READ, allMessagesToRead);
            context.startService(speechIntent);

        }
    }
  }
}

通过单击系统栏通知调用此广播接收器。接收器需要通过特定操作在AndroidManifest.xml上声明。

 <application>(all your stuff)
  <receiver
        android:name=".broadcastreceivers.ReadMessageBroadcastReceiver"
        android:enabled="true">
        <intent-filter>
            <action android:name="com.example.action.ACTION_TTS_READ_MESSAGE" />
        </intent-filter>
    </receiver>
 </application>

您还需要在应用程序中的某个位置声明此操作

public static final String ACTION_TTS_READ_MESSAGE = "com.example.action.ACTION_TTS_READ_MESSAGE";

最后，您需要实现TTS服务本身。我在这里使用了部分代码

public class TextToSpeechService extends Service implements TextToSpeech.OnInitListener {
public final static String TAG = "TextToSpeechService";

public static final String TEXT_TO_READ = "text";
private final String UTTERANCE_ID = "FINISHED_PLAYING";
private final int MULTI_LINE = 2;

private TextToSpeech tts;
private ArrayList<String> texts;
private boolean isInit;

private UtteranceProgressListener utteranceProgressListener = new UtteranceProgressListener() {
    @Override
    public void onStart(String utteranceId) {

    }

    @Override
    public void onDone(String utteranceId) {
        if (utteranceId.equals(UTTERANCE_ID)) {
            stopSelf();
        }
    }

    @Override
    public void onError(String utteranceId) {
        stopSelf();
    }
};

@Override
public void onCreate() {
    super.onCreate();
    tts = new TextToSpeech(getApplicationContext(), this);
    tts.setOnUtteranceProgressListener(utteranceProgressListener);
    Log.d(TAG, "onCreate");

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d(TAG, "onStartCommand");
    texts = intent.getStringArrayListExtra(TTSService.TEXT_TO_READ);

    if (isInit) {
        speak();
    }

    return TextToSpeechService.START_NOT_STICKY;
}

@Override
public void onDestroy() {
    if (tts != null) {
        tts.stop();
        tts.shutdown();
    }
    Log.d(TAG, "onDestroy");
    super.onDestroy();
}

@Override
public void onInit(int status) {
    Log.d(TAG, "onInit");
    if (status == TextToSpeech.SUCCESS) {
        int result = tts.setLanguage(Locale.getDefault());
        if (result != TextToSpeech.LANG_MISSING_DATA
                && result != TextToSpeech.LANG_NOT_SUPPORTED) {
            speak();
            isInit = true;
        }
    }
}

private void speak() {
    if (tts != null) {

        // Speak with 3 parameters deprecated but necessary on pre 21 version codes
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            // This is a single message
            String utteranceId = null;
            if (texts.size() < MULTI_LINE) {
                // If is a single message this needs to be the last one
                utteranceId = UTTERANCE_ID;
            }
            tts.speak(texts.get(0), TextToSpeech.QUEUE_FLUSH, null, utteranceId);
            if (texts.size() >= MULTI_LINE) {
                for (int i = 1; i < texts.size(); i++) {
                    if (texts.size() - 1 == i) {
                        // If is the last message add the id
                        utteranceId = UTTERANCE_ID;
                    }
                    tts.speak(texts.get(i), TextToSpeech.QUEUE_ADD, null, utteranceId);
                }
            }
        } else {
            HashMap<String, String> myHashAlarm = null;
            if (texts.size() < MULTI_LINE) {
                myHashAlarm = new HashMap<>();
                myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, UTTERANCE_ID);
            }
            tts.speak(texts.get(0), TextToSpeech.QUEUE_FLUSH, myHashAlarm);
            if (texts.size() >= MULTI_LINE) {
                for (int i = 1; i < texts.size(); i++) {
                    if (texts.size() - 1 == i) {
                        // If is the last message add the id
                        myHashAlarm = new HashMap<>();
                        myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,
                                UTTERANCE_ID);
                    }
                    tts.speak(texts.get(i), TextToSpeech.QUEUE_ADD, myHashAlarm);
                }
            }
        }
    }
}

@Override
public IBinder onBind(Intent arg0) {
    return null;
}

}

最后，不要忘记在AndroidManifest上注册您的服务。xml文件

<service
    android:name=".services.TextToSpeechService"
    android:exported="false"/>

不利的一面是，我会说启动需要太多时间（根据手机在1秒或2秒之间）。好的一面是，您不会让tts在启动和按需停止时一直运行。实现了一些逻辑来确定是否是系列中的最后一条消息，因为在Intent上传递给服务的参数是ArrayList
