android - 从图库中选择要上传的照片时，应用程序崩溃

Question

在我的应用中，用户可以将图像上传到服务器，但是在某些设备(例如版本为4.4.4。5.0.1和5.1.1的手机)中，甚至对于从“图库”中选择图像的所有设备，应用程序崩溃。但是，当我选择“照片”选项并选择照片并将其上传时，它可以正常工作，那么如何解决此问题并可以从图库或任何相册中选择照片而又不会崩溃也可以将其上传而没有任何问题？

以下是上传图像的完整代码:

public class send extends AppCompatActivity {
private Button buttonChoose;
private Button buttonUpload;

private ImageView imageView;

private EditText editTextName;
private EditText editTextPhone;
private EditText editTextText;
private Bitmap bitmap;

private int PICK_IMAGE_REQUEST = 1;
private static String host=PathConfig.hostName;
private String UPLOAD_URL ="http://"+host+"/upload.php";

private String KEY_IMAGE = "image";
private String KEY_NAME = "name";
private String KEY_PHONE = "phone";
private String KEY_TEXT = "text";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_send);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_send);

    setSupportActionBar(toolbar);
    getSupportActionBar().setHomeAsUpIndicator(R.drawable.arrowb);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); // setting the back arrow in the toolbar
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    setTitle("إرسال شكوى أو إقتراح");

    buttonChoose = (Button) findViewById(R.id.chooseButton);
    buttonUpload = (Button) findViewById(R.id.sendButton);

    editTextName = (EditText) findViewById(R.id.name);
    editTextPhone= (EditText) findViewById(R.id.phone);
    editTextText= (EditText) findViewById(R.id.text);
    imageView  = (ImageView) findViewById(R.id.imageView4);


    buttonChoose.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showFileChooser();
        }
    });
    buttonUpload.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            uploadImage();
        }
    });

}
public String getStringImage(Bitmap bmp){
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    if(bmp!=null){
        bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    }
    byte[] imageBytes = baos.toByteArray();
    String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
    return encodedImage;

我认为您缺少寻求许可的权限。您能检查一下对您有用吗？

   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();
            }

        }
