Android 应用程序无法在模拟器中运行

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:应用程序 Pico TTS(进程 com.svox..pico ) 意外停止。请重试

这是我的 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 self 的 logcat 的消息:

这是我的 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);
 }});

}

那么你认为问题出在哪里呢？!

Answer 1

看起来您正在创建将当前 Activity 作为上下文传递的 TTS 对象。

然后您立即开始一个新 Activity (我假设不要在您的 OnPause 中关闭 TTS 对象)

这会使系统提示，因为您有一个 Activity 的服务与现在不活动的 Activity 相关联。

你应该使用 Activity Lifecycle设置和拆除任何依赖于 Activity 的服务的回调。

例如在 OnResume() 中设置您的 TTS 对象并在 OnPause() 中关闭它
