后按后意图相机崩溃

Question

我正在尝试使用意图相机在我的应用程序中捕获视频，当我拍摄视频并被重定向到主要活动时，它一切正常，但是在我在意图相机模式下按下后退按钮后它崩溃了

我猜你的相机视频意图代码是否 = RESULT_CODE_COMPRESS_VIDEO。然后将如下代码替换为

首先将resCode == RESULT_CODE_COMPRESS_VIDEO.更改为reqCOde 并使用以下代码

if (reqCode == RESULT_CODE_COMPRESS_VIDEO) {
                   if(resCode == RESULT_OK) {
                   if (uri != null) {
                       compress();
                   }
                   }
                   else if(resCode == RESULT_CANCELED && data!=null){
                       Toast.makeText(MainActivity.this,"No Video Recorded",Toast.LENGTH_SHORT).show();
                   }

               }

这不会使您的应用程序在从 Intent 摄像头被背压时崩溃。

希望这会有所帮助！

if (reqCode == RESULT_CODE_COMPRESS_VIDEO) {
                       if(resCode == RESULT_OK) {
                       if (uri != null) {
                           compress();
                       }
                       }
                       else if(resCode == RESULT_CANCELED && data!=null){
                           Toast.makeText(MainActivity.this,"Error !",Toast.LENGTH_LONG).show();
    else return true;                   
    }

                   }

if (requestCode == 1) {

            if(data !=null){
            Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
            //String path = saveImage(thumbnail);
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            byte[] byteArray = stream.toByteArray();

            Glide.with(eventPreview.getContext()).load(byteArray).into(eventPreview);

            int width = eventPreview.getMeasuredWidth();
            eventPreview.getLayoutParams().height = width/2;
            eventPreview.setScaleType(ImageView.ScaleType.FIT_XY);

            postData = byteArray;

            PreviewTXT.setVisibility(View.GONE);}
        }
