Android java.lang.OutOfMemoryError处理来自摄像头的14个数据时出错

我正在制作一个审计应用程序，我必须从单选按钮和14个检查点的图像中收集是/否

该应用程序在我的设备上运行良好，该设备有Android 10设备，但在以任意方式收集4-6幅图像并在各自的Imageview和collect Byte[]字符串变量中显示后，在一些设备上（如牛轧糖设备）进行测试时，该应用程序崩溃，日志中也没有错误（现在通过调试器发现，请参见下文）。请看一下摄像机的编码。应用程序在返回活动时单击照片后崩溃

 public void ClickImageFromCamera(String code) {


        Intent CamIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

        File destination = new File(Environment.getExternalStorageDirectory(),
                System.currentTimeMillis() + ".jpg");
        String img_Decodable_Str = String.valueOf(destination);
        Log.e("img fromCam", String.valueOf(destination));

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            uri = FileProvider.getUriForFile(getActivity(), getActivity().getApplicationContext().getPackageName() + ".provider", destination);
            CamIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, uri);
        } else {
            uri = Uri.fromFile(destination);
            CamIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, uri);
        }
        CamIntent.putExtra("return-data", true);
        startActivityForResult(CamIntent, Integer.parseInt(code));






    }

在调试器中发现错误

好的，我解决了

            int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
            Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
            scaled.compress(Bitmap.CompressFormat.JPEG, 80, byteArrayOutputStream);
            byte[] imageBytes = byteArrayOutputStream.toByteArray();

         
            Log.e("Original   dimensions", bitmap.getWidth() + " " + bitmap.getHeight());
            Log.e("Compressed dimensions", scaled.getWidth() + " " + scaled.getHeight());
              Log.e("bytes", String.valueOf(bytes));

          bitmap =null;

...So on

“应用程序崩溃，日志中也没有错误。”你确定吗？“应用程序在返回活动时单击照片后崩溃。”然后您可以调试

onActivityResult（）

方法一步一步地查看崩溃的确切原因以及变量值，例如，是什么

null

。Ok在调试器java.lang.OutOfMemoryError中发现错误：未能分配14745612字节分配，4194304个空闲字节和8MB，直到OOM听起来像编辑大位图时的问题。Android文档可能会提供一些相关提示。

相机意图在某些设备中崩溃

如果是意图，那么您应该只发布该代码。但似乎只有在onActivityResult被调用并执行所有类型的代码之后。请用真实问题更新你的主题。你在onActivityResult中有太多的可能性。一个就够了。请删除所有其他。为什么previewCapturedImage是previewCapturedImage2？只发布导致问题的一个。举一个简单的例子。

 public void previewCapturedImage1(int code) {

        try {
            //encode base64 string to image
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

            // bimatp factory
            BitmapFactory.Options options = new BitmapFactory.Options();

            // downsizing image as it throws OutOfMemory Exception for larger
            options.inSampleSize = 8;

            bitmap = BitmapFactory.decodeFile(uri.getPath(),
                    options);

            bitmap.compress(Bitmap.CompressFormat.JPEG, 50, byteArrayOutputStream);
            byte[] imageBytes = byteArrayOutputStream.toByteArray();
            // byte[] imageBytes = byteArrayOutputStream.toByteArray();
