当从图库中选择照片进行上传时，应用程序崩溃

Question

在我的应用程序中，用户可以将图像上传到服务器，但在某些设备上，如版本为（4.4.4.5.1和5.1.1）的手机，甚至对于从“图库”中选择图像时所有设备的应用程序崩溃。但是当我选择“照片”选项并选择照片并上传时，它可以正常工作，那么如何解决这个问题，并且可以从图库或任何专辑中选择照片而不会崩溃，也可以毫无问题地上传照片？

下面给出的是上传图片的全码：

public class send extends AppCompatActivity { 
private Button buttonChoose;

我觉得你失踪问permission.Can你检查，这是对你有用吗？

profile_img.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      if (Build.VERSION.SDK_INT >= 23) { 
       // Marshmallow+ 
       if (!checkAccessFineLocationPermission() || !checkAccessCoarseLocationPermission() || !checkWriteExternalStoragePermission()) { 
        requestPermission(); 
       } else { 
        selectImage(); 
       } 
      }else{ 
       selectImage(); 
      } 

     } 
    });
