Android 拾取图片时BitmapFactory.decode文件出现问题

拾取图片时，BitmapFactory.decode文件返回空值。 以下是我的功能：

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Here we need to check if the activity that was triggers was the Image Gallery.
    // If it is the requestCode will match the LOAD_IMAGE_RESULTS value.
    // If the resultCode is RESULT_OK and there is some data we know that an image was picked.
    if (requestCode == SELECT_PHOTO && resultCode == RESULT_OK && data != null) {
        // Let's read picked image data - its URI
        Uri pickedImage = data.getData();
        // Let's read picked image path using content resolver
        String[] filePath = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);
        cursor.moveToFirst();
        String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));

        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap bitmap = BitmapFactory.decodeFile(imagePath,options);
        //imageView.setImageBitmap(bitmap);

        // Do something with the bitmap


        // At the end remember to close the cursor or you will end with the RuntimeException!
        cursor.close();
    }

}

有人能告诉我问题出在哪里吗？

stringimagepath=cursor.getString（cursor.getColumnIndex（filePath[0]）

在变量imagePath中是否有文件路径？或者imagePath值也为空？



更新


您的BitmapFactory.decodeFile（）返回null，原因可能是imageSize太大，并且引发了一些异常

检查日志，查看是否存在outOfMemory位图错误。让我知道
你能更具体地说明你想要实现的目标吗？我试着从图库中挑选一张图片，然后得到它的位图是的，我有一个imagePath，这是我获得的路径示例：/storage/emulated/0/WhatsApp/Media/WhatsApp Images/IMG-20170217-WA0001.jpgI获取此错误：/BitmapFactory:无法解码流：java.io.FileNotFoundException:/storage/emulated/0/WhatsApp/Media/WhatsApp Images/IMG-20170217-WA0001.jpg:打开失败：但我在清单：您是否正在尝试API级别>=23？是的，我使用的是API=23，您使用的设备高于棒棒糖，如果是，您是否提供了运行时权限？
