Android 未捕获且无白屏

Question

我想避免应用程序崩溃，然后我开发了 uncaughtException 方法来调用另一个 Activity ；效果很好。如果应用程序崩溃了任何 Activity ，则会调用 uncaughtException，然后显示我的 ErrorActivity。问题是当我尝试在崩溃后关闭应用程序时。当我按下后退按钮时，ErrorActivity 将关闭，但随后会显示带有操作栏的白屏，几秒钟后，ErrorActivity 会再次被调用。因此，除非在任务管理器中完成应用程序，否则无法关闭应用程序。

@Override
public void onCreate() {
    super.onCreate();

    Thread.setDefaultUncaughtExceptionHandler (new Thread.UncaughtExceptionHandler()
    {
        @Override
        public void uncaughtException (Thread thread, Throwable e)
        {
            handleUncaughtException (thread, e);
        }
    });

}

public void handleUncaughtException (Thread thread, Throwable exception)
{

    StringWriter _stackTrace = new StringWriter();
    exception.printStackTrace(new PrintWriter(_stackTrace));

    Intent _intent = new Intent();
    _intent.setAction ("com.mypackage.ERROR_ACTIVITY");
    _intent.setFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
    _intent.putExtra("error", _stackTrace.toString());
    startActivity(_intent);

    System.exit(0);

}

试试这个:

public void handleUncaughtException (Thread thread, Throwable exception)
{

    StringWriter _stackTrace = new StringWriter();
    exception.printStackTrace(new PrintWriter(_stackTrace));

    Intent _intent = new Intent();
    _intent.setAction ("com.mypackage.ERROR_ACTIVITY");
    _intent.setFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
    _intent.putExtra("error", _stackTrace.toString());
    startActivity(_intent);

    try {
        runOnUiThread(new Runnable() {

        @Override
        public void run() {
            finish();
        }
        });
            Thread.sleep(300);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }    
}
