Android 5.1.1默认相机在捕获图像后在onActivityResult中返回空意图

Question

我有以下代码，它要求用户从照片应用程序中选择一个图像或通过相机应用程序捕捉一个图像：

    // Camera
    final List<Intent> cameraIntents = new ArrayList<Intent>();
    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    final PackageManager packageManager = fragment.getActivity().getPackageManager();
    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for(ResolveInfo res : listCam) {
        final String packageName = res.activityInfo.packageName;
        final Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(packageName);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        cameraIntents.add(intent);
    }

    // Filesystem.
    final Intent galleryIntent = new Intent();
    galleryIntent.setType("image/*");
    galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

    // Chooser of filesystem options.
    final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");

    // Add the camera options.
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));

    fragment.startActivityForResult(chooserIntent, UPLOAD_IMAGE_ACTIVITY_REQUEST_CODE);

和OnActivityResult的代码：

if(requestCode == UPLOAD_IMAGE_ACTIVITY_REQUEST_CODE)
{
    final boolean isCamera;
    if(data == null)
    {
        isCamera = true;
    }
    else
    {
        final String action = data.getAction(); // data is always empty here after capture image by default camera in 5.1.1!
        if(action == null)
        {
            isCamera = false;
        }
        else
        {
            isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        }
    }

    //do sth according to value of isCamera

}

我又增加了一个条件。在5.1.1和不同的API级别中，它似乎工作得很好，没有任何问题

if(data == null){
 isCamera = true;
}else if(data.getData() == null){
 isCamera = true;
}
else{
  //....
