Android studio用模拟机拍照可以显示图片，在真机模拟却不行

takePhoto.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                File outputImage = new File(getExternalCacheDir(), "output_image.jpg");
                try{
                    if (outputImage.exists()){
                        outputImage.delete();
                    }
                    outputImage.createNewFile();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                if (Build.VERSION.SDK_INT >= 24){
                    imageUri = FileProvider.getUriForFile(sign.this,
                            "com.example.nyiji.signin.fileprovider", outputImage);
                }else {
                    imageUri = Uri.fromFile(outputImage);
                }
                Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                startActivityForResult(intent, TAKE_PHOTO);
            }
        });
    }

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    switch (requestCode){
        case TAKE_PHOTO:
            if(resultCode == RESULT_OK){
                try {
                    Bitmap bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(imageUri));
                    picture.setImageBitmap(bitmap);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
            }
            break;
        default:
            break;
    }
}

有崩溃吗,手机型号?有做权限申请?我记得github有个photoview开源项目,可以试着用下

我也遇到了，不知道是不是版本号不一样的问题，可能是真机是android10的原因，要裂开了
