启动相机需要大量内存。因此，在内存不足的设备上，android系统会关闭在后台运行的Activity，因此会调用onCreate()。由于此光路，您提供的光路变为空，因此您将无法获取已保存的图像。解决方法是在系统破坏您的活动时保存光路径，然后再次恢复它。@Override    public void onSaveInstanceState(Bundle outState) {        // TODO Auto-generated method stub            outState.putString("photopath", photopath);        super.onSaveInstanceState(outState);    }    @Override    protected void onRestoreInstanceState(Bundle savedInstanceState) {        // TODO Auto-generated method stub        if (savedInstanceState != null) {            if (savedInstanceState.containsKey("photopath")) {                photopath = savedInstanceState.getString("photopath");            }        }        super.onRestoreInstanceState(savedInstanceState);    }并且如果您正在Fragment上执行此操作。@Override    public void onSaveInstanceState(Bundle outState) {        // TODO Auto-generated method stub            outState.putString("photopath", photopath));        super.onSaveInstanceState(outState);    }    @Override    public void onViewStateRestored(Bundle savedInstanceState) {        // TODO Auto-generated method stub        if (savedInstanceState != null) {            if (savedInstanceState.containsKey("photopath")) {                photopath = savedInstanceState.getString("photopath");            }        }        super.onViewStateRestored(savedInstanceState);    }
