MyActivity 是从 SherlockFragmentActivity 扩展而来的。我正在使用proguard。我的 project-proguard.tx 确实包含

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class com.actionbarsherlock.** { *; }
-keep interface com.actionbarsherlock.** { *; }

这是堆栈跟踪。奇怪的是，这看起来不像我的代码的问题。它追溯到支持库。

=====================

下面是 onSavedInstanceState() 和 onRestoreInstanceState()，以及 onCreate() 的一部分，在 onCreate() 中有一些从 savedInstanceState 读取的内容，所以我将其包含在此处。

private int recognize = 0;
private ArrayList<ToFree> to_free = null;

@Override
public void onCreate(Bundle savedInstanceState) {
......

if(savedInstanceState!=null)
{
  language_type = savedInstanceState.getInt("language_type");
  save_binary = savedInstanceState.getBoolean("save_binary", false);

  line_content =
    savedInstanceState.getParcelableArrayList("line_content");
}

......

if(bitmap != null && savedInstanceState != null)
{
  final float[] m;
  final ArrayList<FloatPoint> flow;
  final ArrayList<FloatPoint2> filler;

  {
    m = savedInstanceState.getFloatArray("matrix");
    flow = savedInstanceState.getParcelableArrayList("reading_flow");
    filler = savedInstanceState.getParcelableArrayList("filler");
    show_flow = savedInstanceState.getBoolean("show_flow");
  }

 .....
}


protected void onSaveInstanceState(Bundle outState) {
outState.putInt("language_type", language_type);
if(save_binary)
  outState.putBoolean("save_binary", save_binary);
outState.putBoolean("show_flow", show_flow);
if(line_content != null)
  outState.putParcelableArrayList("line_content", line_content);

if(to_free != null && !to_free.isEmpty())
  outState.putParcelableArrayList("to_free", to_free);
if(recognize != 0)
{
  outState.putInt("recognize", recognize);
  recognize = 0;
}

if(data != null && data.page != 0)
{
  outState.putInt("page", data.page);

  outState.putBoolean("running", data.running);

  outState.putInt("ret", data.ret);
  outState.putBoolean("rgb_set", data.rgb_set);
  data.page_saved = data.page;
}

if(bitmap != null)
{
  float[] m = imageView.get_matrix();
  outState.putFloatArray("matrix", m);

  ArrayList<FloatPoint> flow = imageView.get_point_list();
  if(flow != null && flow.size()>0)
    outState.putParcelableArrayList("reading_flow", flow);

  ArrayList<FloatPoint2> filler = imageView.get_point_pair_edit_list();
  if(filler != null && filler.size()>0)
    outState.putParcelableArrayList("filler", filler);
}

super.onSaveInstanceState(outState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);

to_free = savedInstanceState.getParcelableArrayList("to_free");

recognize = savedInstanceState.getInt("recognize", 0);
int page = savedInstanceState.getInt("page", 0);
if(page != 0)
{
  data = new DataNative();
  data.rgb_set = false;
  data.running = savedInstanceState.getBoolean("running", false);
  data.ret = savedInstanceState.getInt("ret", 0);
  data.rgb_set = savedInstanceState.getBoolean("rgb_set", false);
}
