android - 无法从画廊提供结果

我有一个处理从图库中选择的图片的应用程序。但是使用这样的堆栈跟踪会导致 ICS 崩溃:

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, Intent { dat=content://com.google.android.gallery3d.provider/picasa/item/5629933319233370946 }} to activity {com.myexample/com.myexample.activities.UserProfileActivity}: java.lang.NullPointerException

我已经找到了一些关于此类错误的信息，但是我可以避免这种情况吗？如何避免？

编辑:
我的代码:

private void getImageFromGallery() {
        Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
        startActivityForResult(galleryIntent, GALLERY_PIC_REQUEST);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == CAMERA_PIC_REQUEST) {
            try {
                captureFile = new File(getCaptureFilePath());
                captureUri = Uri.fromFile(captureFile);

                Bitmap scaledBitmap = decodeFileAndResize(captureFile);
                saveResizedAndCompressedBitmap(scaledBitmap);

                Bitmap rotatedBitmap = convertToRotatedBitmap(scaledBitmap);
                driverPhoto.setImageBitmap(rotatedBitmap);

                if (rotatedBitmap != scaledBitmap) {
                    scaledBitmap.recycle();
                    scaledBitmap = null;
                    System.gc();
                }
            } catch (IOException e) {
                BugSenseHandler.log(TAG, e);
            }
        } else if (requestCode == GALLERY_PIC_REQUEST) {
            try {
                captureFile = new File(getCaptureFilePath());
                captureUri = Uri.fromFile(captureFile);

                Uri chosenUri = data.getData();

                String[] filePathColumn = {MediaStore.Images.Media.DATA};

                Cursor cursor = getContentResolver().query(chosenUri, filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String filePath = cursor.getString(columnIndex);
                cursor.close();

                File chosenFile = new File(filePath);

                Bitmap selectedImageBitmap = decodeFileAndResize(chosenFile);
                saveResizedAndCompressedBitmap(selectedImageBitmap);
                driverPhoto.setImageBitmap(selectedImageBitmap);
            } catch (IOException ie) {
                BugSenseHandler.log(TAG, ie);
            }
        }
    }
}

最佳答案

这可能有助于阻止它列出不在 SD 卡上的项目:

galleryIntent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
