Question

我正在尝试通过从手机的图片库中选择图片来上传图片。但是，选择它后根本不执行任何操作，甚至不上传它。

我尝试清理构建并重新构建仍然没有帮助。

它会自动断开：

V / FA：已在尝试连接D / FA：已连接到远程服务V / FA：处理排队的服务任务：2 V / FA：不活动，与服务断开连接

public class MainActivity extends AppCompatActivity {

    Button uploadButton;
    ImageView downloadedImage;
    private static final int CAMERA_REQUEST_CODE=1;
    private StorageReference storageReference;
    //private ProgressDialog progressDialog;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        uploadButton = findViewById(R.id.button);
        downloadedImage = findViewById(R.id.imageView);
        storageReference = FirebaseStorage.getInstance().getReference();

        //progressDialog = new ProgressDialog(this);

        uploadButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                Intent intent =  new Intent(Intent.ACTION_PICK);
                intent.setType("image/*");
                startActivityForResult(intent,CAMERA_REQUEST_CODE);
                Log.i("Done","Till here");
            }
        });

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == CAMERA_REQUEST_CODE && requestCode == RESULT_OK)
        {

            Log.i("Not Done","This log is not visible");

            Uri uri = data.getData();
            StorageReference filepath = storageReference.child("Photo").child(uri.getLastPathSegment());
            filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    //progressDialog.dismiss();
                    Toast.makeText(MainActivity.this,"Uploaded...",Toast.LENGTH_LONG).show();
                }
            });


        }
    }
}

我得到的错误是：

I / art：拒绝对先前失败的类进行重新初始化 java.lang.Class： java.lang.NoClassDefFoundError：无法解决以下问题： Landroid / view / View $ OnUnhandledKeyEventListener;

Answer 1

在&&之后将requestCode更改为resultCode，它将起作用。

if(requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK)
{
}

由于拒绝先前失败的类java.lang.Class错误
