Question

我正在开发一个Android应用程序，在我点击运行后，我解锁AVD并单击菜单加载我的应用程序，我立即收到此消息：The application Pico TTS (process com.svox..pico) has stopped unexpectedly. Please try again

我的AndroidManifest.xml：

    <application android:icon="@drawable/icon" android:label="@string/app_name" android:allowBackup="true">
        <activity android:name=".MPActivity"
                  android:label="@string/app_name"
                  >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
</manifest>

这些是来自我的logcat的消息：

我的onCreate：

 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
     Button buttonLoadImage = (Button)findViewById(R.id.loadimage);

 textView    = (TextView) findViewById(R.id.textView);
 textViewCol = (TextView) findViewById(R.id.textViewColor);
 targetImage = (ImageView) findViewById(R.id.targetimage);
 textViewVal = (TextView) findViewById(R.id.textViewValue);

  mTts = new TextToSpeech(this, new OnInitListener() {      
    @Override
    public void onInit(int status) {
    TTSInitialized = true;
    }
  });

  Intent installIntent = new Intent();
  installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
  startActivity(installIntent);

 buttonLoadImage.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
  startActivityForResult(intent, 0);
 }});

}

那么您认为问题在哪里？！

Answer 1

看起来您正在创建将当前活动作为上下文传递的TTS对象。

然后你立即开始一个新的活动（我假设不要关闭OnPause中的TTS对象）

这会让系统抱怨，因为您有一个与现在非活动活动相关联的活动服务。

您应该使用Activity Lifecycle回调来设置和拆除依赖于活动的所有服务。

例如在OnResume（）中设置TTS对象并在OnPause（）中将其关闭

Answer 2

听起来好像你有一个加载一次的广播监听器然后没有按预期发布。如果是这种情况，那么您需要分析覆盖该广播接收器的应用程序的生命周期，并确保它在之前启动的活动时关闭。如果需要，您甚至可以在创建广播时将其包围在try catch中并且不执行任何操作。因为Android将为您处理冲突，并在其他所有方法都失败时默默地失败;显然找到合适的关闭是理想的。

这就是我能从所提供的内容中推断出的一切。

Android应用程序在模拟器中不起作用
