java - Android 应用程序在四个特定 Activity 中崩溃

Question

我在四个特定 Activity 的 Intent 上遇到了一些麻烦。它随机崩溃，我不明白为什么会这样。它发生在四个 Activity 中，我认为这与 Activity 没有正确接收 Intent 有关。我使用了差异检查器来验证此代码与不会崩溃的 Activity 之间没有任何不同，并且没有发现任何差异。更有趣的是，它似乎重新启动了崩溃之前的 Activity ，并正常继续经过该 Activity 而没有崩溃，但随后在这四个 Activity 中的另一个 Activity 上崩溃。

这是我的 Logcat:

如果我需要发布更多代码/logcat 读数，请告诉我。我是这方面的新手，所以请尽可能彻底地解释你的答案。

谢谢。

@Override

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.hdmi, menu);
    return true;
}

@Override

    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.

    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);

看起来你在主线程上做了太多的事情并加载了一个非常大的图像(在主线程上不好)。该镜像导致您的虚拟机耗尽堆内存:
08-15 20:08:05.380 1547-1547/tk.emposoft.wirewizard E/dalvikvm-heap: 106990144 字节分配内存不足。


您需要在读入图像时对其进行缩放，并在后台线程上进行加载。
