Question

我正在创建一个插件，以使用虚幻插件语言将UE4应用程序连接到android语言。我创建了两个函数：

public void AndroidThunkJava_AndroidAPI_ShowToast(final String toast) {
    runOnUiThread(new Runnable() {
        public void run() {
            CharSequence cs = toast;
            Toast.makeText(getApplicationContext(), cs, Toast.LENGTH_LONG).show();
        }
    });
}
public void AndroidThunkJava_AndroidAPI_CheckRecording() {
    if(!isListening){
        startRecording();
        if(mRecorder.getMaxAmplitude() > 1000){
            stopRecording();
            runOnUiThread(new Runnable() {
                public void run() {
                    startSpeechRecognition();
                    speechRecognizer.startListening(speechRecognizerIntent);
                }
            });                 
        }
    }
}

绑定有效，我可以从C ++调用这两个函数。问题是，当我调用第二个函数时，代码出现在这一部分：speechRecognizer.startListening(speechRecognizerIntent);，该应用程序刚刚停止，并且在以下线程上，AndroidStudio：SIGABRT (signal SIGABRT)上出现了以下错误：

当我从OnCreate调用时，startSpeechRecognition和speechRecognizer.startListening(speechRecognizerIntent);可以这样工作：

<gameActivityOnCreateAdditions>
    <insert>
        <![CDATA[   
            startSpeechRecognition();
            speechRecognizer.startListening(speechRecognizerIntent);
        ]]>
    </insert>
</gameActivityOnCreateAdditions>

如何使SIGABRT（信号SIGABRT）停止发生
