我正在按照这个 Dropbox 教程来启动和设置我的“Hello Dropbox 同步应用程序”。
尽管我将按照教程中给出的步骤进行操作，但我会遇到错误。
权限、应用程序密钥、应用程序秘密等都在他们的位置上，但仍然没有得到我要去的地方。请帮助我摆脱困境。提前致谢
这是我的 Manifest.xml ：

爪哇代码：
public class MyDropboxDemoActivity extends Activity implements OnClickListener
{
Button btnLinkToDropbox;
DbxAccountManager dropBoxAcMngr;
static final int REQUEST_LINK_TO_DROPBOX = 444;
static final String APP_KEY = "MY_APP_KEY";
static final String APP_SECRET = "MY_APP_SECRET";
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_dropbox_demo);
dropBoxAcMngr = DbxAccountManager.getInstance(this, APP_KEY , APP_SECRET);
btnLinkToDropbox = (Button) findViewById(R.id.btnLinkDropboxAC);
btnLinkToDropbox.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
dropBoxAcMngr.startLink(getParent(), REQUEST_LINK_TO_DROPBOX);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if(requestCode == REQUEST_LINK_TO_DROPBOX)

if(resultCode == Activity.RESULT_OK)
{
btnLinkToDropbox.setText("Successfully Linked To Your Dropbox Account");
btnLinkToDropbox.setEnabled(false);
Toast.makeText(this, "Account Linked", Toast.LENGTH_LONG).show();
}
else
{
btnLinkToDropbox.setText("Failed to Link Your Dropbox Account\nTry Again?");
Toast.makeText(getApplicationContext(), "Account Linking failed", Toast.LENGTH_LONG).show();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
}
