Question

我想使用默认相机拍摄图像并将其保存在内部存储中。我希望在sdcard / camera_app /中保存图像，并将文件名保存为sdcard / camera_app中的cam_image.jpg，并在imageview页面中显示捕获图像。此代码适用于Android M，但它不适用于API级别24（牛轧糖）或以上。

给我一个错误消息 file：///sdcard/camera_app/cam_image.jpg通过ClipData.Item.getUri（）

在app之外暴露

关于这个的任何想法？谢谢你的意见

这是代码

btnCapturePicture.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            try
            {
                Intent camera_intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File file=getFile();
                camera_intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
                startActivityForResult(camera_intent,CAM_REQUEST);
                Log.d("MainActivity"," saved");
                Toast.makeText(getApplicationContext()," saved ",Toast.LENGTH_SHORT).show();
            }
            catch (Exception e)
            {
                Log.d("MainActivity"," error = "+e.getMessage().toString());
                Toast.makeText(getApplicationContext()," error = "+e.getMessage().toString(),Toast.LENGTH_SHORT).show();
            }
            //captureImage();
        }
    });

private File getFile()
{
    File folder=new File("sdcard/camera_app");

    if(!folder.exists())
    {
        folder.mkdir();
    }

    File image_file=new File(folder,"cam_image.jpg");
    return  image_file;
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    String path="sdcard/camera_app/cam_image.jpg";
    imgPreview.setImageDrawable(Drawable.createFromPath(path));
}

这是我的登录，我打印异常
