我正在開發手指繪畫應用程序。我有以下代碼從圖庫加載圖片（以繪製它）。代碼在我的智能手機（Android 4.2.2 - API 17）中工作正常。但是當我在較低版本（2.3.3等）上運行它時，它只是顯示運行時錯誤並且應用程序已關閉。圖像庫中加載圖片時出現異常
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)
try {
// We need to recyle unused bitmaps
if (bitmap != null) {
bitmap.recycle();
}
InputStream stream = getContentResolver().openInputStream(
data.getData());
myBitmap = BitmapFactory.decodeStream(stream);
stream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
和調用這個
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(intent, REQUEST_CODE);
在我的理解，這個代碼應工作的所有的API。但是低版本存在一些問題。請幫我
