在启用了HA的情况下返回前台时，Android视图变得混乱

// 使用Handler确保在主线程更新UI
new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
        // 更新UI的代码
    }
});

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    // 保存关键状态
    outState.putString("key", "value");
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    // 恢复关键状态
    String value = savedInstanceState.getString("key");
}

private final Object lock = new Object();

public void updateData() {
    synchronized (lock) {
        // 更新数据的代码
    }
}

// 使用try-with-resources确保资源被正确关闭
try (InputStream is = new FileInputStream("file.txt")) {
    // 使用资源的代码
} catch (IOException e) {
    e.printStackTrace();
}
