OutOfMemory在解码和编码Base64字符串为位图时出错

base64 image android java bitmap

2022-09-01 05:16:09

我正在尝试和图像。在某些设备上，它可以完美运行，而在另一些设备上则不然。我正在上传到服务器并从服务器获取。我已经找到了各种解决方案，但仍然无法解决我的问题。这是我的代码：decodeencodeBitmapBase64 StringBase64 String

编码：

button1.setOnClickListener(new OnClickListener() {    
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                getActivity().startActivityForResult(i, RESULT_LOAD_IMAGE);
            }
});



//Image loading from Gallery
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
                && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

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

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

            imageView1.setImageBitmap(BitmapFactory.decodeFile(picturePath));

            if (picturePath != null && !TextUtils.isEmpty(picturePath)) {
                BitmapFactory.Options options = new BitmapFactory.Options();
                options.inPreferredConfig = Bitmap.Config.ARGB_8888;
                Bitmap bitmap = BitmapFactory.decodeFile(picturePath, options);
                base64ImageSend = ImageBase64.encodeTobase64(bitmap);
                Log.i("Base 64 Image", base64ImageSend);
            } else {
                base64ImageSend = "";
            }

        }
}

我已经尝试过的解决方案是：

答案 1

当从文件显示时，首先在它的帮助下对其进行解码将返回压缩，以便在对此位图进行编码时，您可以处理高分辨率图像以及高达100 MB文件的大尺寸图像。BitmapImageViewBitmapHelper.decodeFile(picturePath, 200, 200, true)Bitmap

解码文件后将其设置为您的，并使用类获得压缩图像上方的字符串形式;从您的（即已经压缩）中获取，并使用这将再次压缩文件并使句柄异常，而.ImageViewBase64BitmapHelperBitmapImageViewImageBase64.encodeTobase64(bitmap)OutOfMemoryEncodingBitmap

首先将文件写入设备内存中。然后以块的形式读取并解码，这样您就可以在内存中拥有位图。在此使用方法缩小此位图之后，您将从decodingBase64StringBytesByteArraydecodeFile()BitmapBase64String

我搜索了各种博客和帖子，从中我采用了最合适的代码，并将它们组合成一个，以使其更加可靠。尝试下面的代码，使和更快的记忆管理。encodingdecoding

解码Base64String

Bitmap bitmap = ImageBase64.decodeBase64(base64ImageStr,MainActivity.this);
imageView.setImageBitmap(bitmap);
bitmap = null;
System.gc();

要进行编码，请尝试以下操作：Bitmap

imageView.setImageBitmap(BitmapHelper.decodeFile(picturePath, 200, 200, true));

Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();              
base64ImageStr = ImageBase64.encodeTobase64(bitmap);

我建议你：

如果使用基于 xml 的协议从服务器接收数据，请使用 SAX 解析器而不是 DOM。
不要将整个 base64 字符串加载到内存中。用于将部分数据加载到数组中，从数组解码 Base64，并通过将结果追加到缓存文件中。InputStreambyte[]FileOutputStream
使用 options.inJustDecodeBounds 选项可防止将全尺寸位图文件加载到内存中。例如，您可以评估所需的内存总量，并决定将其缩小。UPD。我注意到你已经在使用它了。
请记住，您正在持有并通过方法流传递的对象引用。强引用可防止 GC 回收内存。

遵循您的代码：方法在堆栈中保存参数，引用并在最后返回。同时将所有这些对象保存在内存中意味着对GC和内存分配的巨大压力。作为最简单的解决方案，您可以在使用相应的对象（字符串和字节数组）后立即引用，因此GC将能够释放它们。decodeBase64String inputbyte[] decodedByteBitmapFactory.decodeStream(new FileInputStream(f), null, o2)null
