标签: illegalstateexception

这让我疯狂了好几天了.我有一个非常复杂的Android应用程序.它使用多个线程从服务器提取数据并填充SQLite数据库.我正在使用单例来引用我的SQLiteOpenHelper扩展.我在每个活动中打开和关闭数据库.

该错误仅发生在我4次活动深度然后尝试退出的情况下.我已经尝试了各种方法来打开和关闭数据库,包括将关闭从onDestroy()移动到onPause()方法,还添加另一个打开到onResume().

另外值得注意的是,我的活动大量使用了ListViews和ExpandableListViews,据我所知,这可能会导致数据库关闭,基于这篇文章:http: //darutk-oboegaki.blogspot.com/2011/03/sqlitedatabase-is-closed- automatically.html

我已经完成了代码并确保我要么关闭所有游标,要么将它们分配给适配器,调用startManagingCursor().

有没有人知道发生了什么？

更新: 我已经修复了问题,但不确定为什么要修复它.所以,也许有人知道或可以解释.

当我处于活动堆栈的第4个活动时,我试图通过db.close()关闭数据库.无论我把它放在哪里,在我得到我需要的数据之后的onCreate中,或者在onStop或onDestroy中,它都会产生这个错误.如果我不关闭数据库,我没有问题.因此,导致数据库自动关闭的原因.奇怪的是,虽然我在最后的活动中使用了expandableListView,但我没有使用cursorAdapter.有人有什么想法？很想明白这一点.

我正在尝试将带有Android的UDP数据包发送到我的计算机上用C#编写的服务器.当我在手机上运行应用程序时,我会收到非法状态异常.我认为这可能与在主要活动上执行网络操作有关,但我不知道如何解决这个问题.这是我的客户:

public class MainActivity extends Activity {

WifiManager wifi;
InetAddress dev_ip;
final int serverPort = 31337;
Thread drawThread = new Thread(new drawer());

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //set up wifi and connection
    wifi = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
    WifiInfo info = wifi.getConnectionInfo();
    int ip = info.getIpAddress();        
    String ipaddr = (ip & 0xff) + "." + (ip >> 8 & 0xff) + "." + (ip >> 16 & 0xff) + "." + (ip >> 24 & 0xff);

    try {
        dev_ip …

每当我加载片段的主要活动并且用户启动新活动,切换设备的方向并返回主活动时,我就会收到此错误.

@Override
public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.home_layout);
    super.onCreate(savedInstanceState);
    fragmentManager = getSupportFragmentManager();
    fragment = fragmentManager.findFragmentById(R.id.layFragment);

    initialize();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    setContentView(R.layout.home_layout);
    initialize();
    super.onConfigurationChanged(newConfig);
}

private void initialize() {
    layStatus = (LinearLayout) findViewById(R.id.layStatus);
    txtStatus = (TextView) findViewById(R.id.txtStatus);
    ....
    handleFragments(lastFragmentId);
}

public void handleFragments(int fragmentId) {
        if (fragment == null) {
            FragmentTransaction ft = fragmentManager.beginTransaction();
            if (fragmentId==someFragmentId){
                ft.replace(R.id.layFragment, new FragmentSomeFragment());
            }
            else
            ....

            ft.commit();
        }
}

在我的android清单中,活动被声明为:

 <activity
        android:name=".HomeActivity"
        android:configChanges="keyboardHidden|orientation" />
<activity

在另一个关于SO的问题中,我发现这可能是由支持库中的一个错误造成的,我添加没有任何运气:

// needed as a workaround for …

我刚刚遇到了JavaFX和Swing的奇怪之处.

处理已添加到JFrame或JPanel的JavaFX Panel时,重新添加新的JFXPanel将抛出IllegalStateException:"已调用Platform.exit".

在我的情况下,这是在我用JFXPanels删除了一些JPanels然后尝试重新添加它们之后发生的.

我在此活动中收到IllegalStateException但不太确定发生了什么.这是QuickContactActivity中的ViewPagerAdapter类.

private class ViewPagerAdapter extends FragmentPagerAdapter {
    public ViewPagerAdapter(FragmentManager fragmentManager) {
        super(fragmentManager);
    }

    @Override
    public Fragment getItem(int position) {
        QuickContactListFragment fragment = new QuickContactListFragment();
        final String mimeType = mSortedActionMimeTypes.get(position);
        final List<Action> actions = mActions.get(mimeType);
        fragment.setActions(actions);
        return fragment;
    }

    @Override
    public int getCount() {
        return mSortedActionMimeTypes.size();
    }
}

这是崩溃日志:

我正在开发一个启动器应用程序,当用户验证自身时会显示对话框碎片.大部分时间这都运行良好,但有时我有这个错误日志:

我可以看到在多个设备上引发了异常，但使用该异常的字符串从Google的测试类中找不到任何异常。您有什么暗示为什么会这样吗？

I am using a FragmentActivity and sometimes on Crashlytics, I am able to see an exception Fatal Exception: java.lang.RuntimeException: Unable to pause activity

Below is the onPause of my FragmentActivity

@Override
protected void onPause() {
    super.onPause();
    if (EventBus.getDefault().isRegistered(this))
        EventBus.getDefault().unregister(this);
}

Here is the stack trace of this crash.

我正在尝试录制音频,但是类的start()方法会MediaRecorder抛出一个IllegalStateException.我使用以下代码:

MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile("/sdcard/");
try {
    recorder.prepare();
} catch (IllegalStateException e) {

// TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
Log.i("Try","Exception");
recorder.start();

我正在开发一个Android应用程序.在这个应用程序中,我在片段中显示MapView.如果我的设备旋转,我尝试使用以下方法之一移动相机:

mapa.animateCamera(cameraUpdate);

要么

mapa.moveCamera(cameraUpdate);
