How can I launch an ACTION_VOICE_COMMAND Intent from a Service?

Question

I have the following code to launch an Intent in my service:

Intent voiceCommandIntent = new Intent(Intent.ACTION_VOICE_COMMAND);
            voiceCommandIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            appContext.startActivity(voiceCommandIntent);

I get the error

No Activity Found to Handle Intent

Here is the stacktrace:

I just want the Android Voice Command Prompt to appear. How can I do this?

Answer 1

You should simply broadcast the intent. then the system grabs it and starts the Voice command app. Intent broadcast = new Intent(); broadcast.setAction(Intent.ACTION_VOICE_COMMAND); sendBroadcast(broadcast);

Answer 2

It seems that noone in your "device" is able to handle that Intent with Action ACTION_VOICE_COMMAND.

The code you posted is ok. That's the right way of launching Intents from a Service.
