android - 扩展另一个 Activity 的失败保存 Activity 状态

Question

我的问题如下。 我有 BasicPhotoTakingActivity extends SherlockFragmentActivity，它有所有拍照方法，如 takePhoto() loadFromGallery() 等。

现在我有另一个扩展 BasicPhotoTakingActivity 的 Activity 。

由于某些原因，应用程序在 SaveInstanceState 上崩溃，例如在旋转设备屏幕时。

代码如下:

ActivityWhichExtendsBasicPhotoTakingActivity onSaveInstanceState:

@Override
protected void onSaveInstanceState(Bundle outState) {

    outState.putInt("state", currentStage.ordinal());

    super.onSaveInstanceState(outState);
}

SaveInstanceState 上的基本拍照 Activity :

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putString("imageUri", mCurrentPhotoPath);
    if (bitmap != null) {
        Logger.d(TAG, "Bitmap != null. Saving: " + bitmap.toString());
        outState.putBoolean("bitmap", true);
    }
    super.onSaveInstanceState(outState);
}

崩溃日志:

Answer 1

试试这个，

@Override
protected void onSaveInstanceState(Bundle outState) {
    if (outState!= null && outState.size() > 0) {

}
