java在Dropbox API上创建新数据存储错误消息：com。投递箱。同步。安卓DbxRuntimeException$缓存：
我正在开发一个应用程序来制作购物清单。这些列表的内容存储在数据库的表中。我的目标是在多个设备之间共享其中一些表。通过这种方式，我选择在Dropbox数据存储上发送这些表
在第一步中，我尝试按照本教程here创建一个新的Dropbox数据存储。但在我的真实设备（Android 4.2.2）上运行我的应用程序后，我被一条错误消息卡住了。下面我将显示错误消息、代码活动和清单
错误消息：

通过使用Eclipse的调试模式运行我的应用程序，我知道问题的关键是：
try {
// This line makes my app to stop.
DbxDatastore datastore = mDatastoreManager.openOrCreateDatastore("articles");
} catch (DbxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
活动代码（ListingArticlesDropb.java）：
public class ListingArticlesDropb extends Activity implements PersonneAdapterListener{
static final int REQUEST_LINK_TO_DBX = 0; // This value is up to you
private Button mLinkButton;
private Button mUnlinkButton;
private DbxAccountManager mAccountManager;
private DbxDatastoreManager mDatastoreManager;
private DbxAccount account ;
final private String APP_KEY = **** APP_KEY **** ;
final private String APP_SECRET = **** APP_SECRET **** ;
DbxDatastore datastore;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_articles);
/**
* Get objects from the precedent activity
*/
Bundle bundle = getIntent().getExtras();
final String extras = bundle.getString("Title");
/**
* Connection to the datastore Dropbox
*/
// Set up the account manager
mAccountManager = DbxAccountManager.getInstance(getApplicationContext(), APP_KEY, APP_SECRET);
mAccountManager.startLink((Activity)ListingArticlesDropb.this, REQUEST_LINK_TO_DBX);
// Set up the datastore manager
if (mAccountManager.hasLinkedAccount()) {
try {
// Use Dropbox datastores
mDatastoreManager = DbxDatastoreManager.forAccount(mAccountManager.getLinkedAccount());
Toast.makeText(this, "Connection Dropbox", Toast.LENGTH_LONG).show();
} catch (DbxException.Unauthorized e) {
System.out.println("Account was unlinked remotely");
}
}
if (mDatastoreManager == null) {
// Account isn't linked yet, use local datastores
mDatastoreManager = DbxDatastoreManager.localManager(mAccountManager);
Toast.makeText(this, "Connection Locale", Toast.LENGTH_LONG).show();
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_LINK_TO_DBX) {
if (resultCode == Activity.RESULT_OK) {
account = mAccountManager.getLinkedAccount();
Toast.makeText(this, "onActivityResult", Toast.LENGTH_LONG).show();
try {
// Migrate any local datastores to the linked account
mDatastoreManager.migrateToAccount(account);
// Now use Dropbox datastores
mDatastoreManager = DbxDatastoreManager.forAccount(account);
} catch (DbxException e) {
e.printStackTrace();
}
} else {
// Link failed or was cancelled by the user
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
// ---------- The problem comes here ------------- //
try {
// This line makes my app to stop.
DbxDatastore datastore = mDatastoreManager.openOrCreateDatastore("articles");
} catch (DbxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
