我正在尝试让 Salesforce REST API 与 Android 和新的 android 编程一起使用，按照示例代码连接 SFDC http://wiki.developerforce.com/page/Getting_Started_with_the_Mobile_SDK_for_Android#Authentication
我正在尝试从 SFDC 获取一些记录并将它们显示在 android 应用程序中，看起来像在“client.sendAsync(sfRequest, new AsyncRequestCallback()”处进行异步调用时 - 抛出 NullPointerException。
我确实在网上看到了一些类似的问题，但没有帮助我。希望有人能指出我正确的方向来解决这个问题。非常感谢。
public class GetAccountsActivity extends Activity {
private PasscodeManager passcodeManager;
private String soql;
private String apiVersion;
private RestClient client;
private TextView resultText;
private RestRequest sfRequest;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get Api Version
apiVersion = getString(R.string.api_version);
//Create Query
soql = "select id, name from Account limit 10";
// Setup view
setContentView(R.layout.get_accounts_activity);
((TextView) findViewById(R.id.Acc_Title)).setText(apiVersion);
// Passcode manager
passcodeManager = ForceApp.APP.getPasscodeManager();
}
@Override
public void onResume() {
super.onResume();
//Get SFClient
// Login options
String accountType = ForceApp.APP.getAccountType();
LoginOptions loginOptions = new LoginOptions(
null, // login host is chosen by user through the server picker
ForceApp.APP.getPasscodeHash(),
getString(R.string.oauth_callback_url),
getString(R.string.oauth_client_id),
new String[] {"api"});
new ClientManager(this, accountType, loginOptions).getRestClient(this, new RestClientCallback() {
@Override
public void authenticatedRestClient(RestClient client) {
if (client == null) {
ForceApp.APP.logout(GetAccountsActivity.this);
return;
}
GetAccountsActivity.this.client = client;
}
});
//Get Rest Object to query
try {
sfRequest = RestRequest.getRequestForQuery(apiVersion, soql);
//Use SF Rest Client to send the request
client.sendAsync(sfRequest, new AsyncRequestCallback(){
@Override
public void onSuccess(RestRequest request, RestResponse response){
//Check responses and display results
// EventsObservable.get().notifyEvent(EventType.RenditionComplete);
}//end onSuccess
@Override
public void onError(Exception exception) {
//printException(exception);
EventsObservable.get().notifyEvent(EventType.RenditionComplete);
}//End Exception for Async Method
});
}catch (UnsupportedEncodingException e) {
//printHeader("Could Send Query request");
//printException(e);
return;
}
}
}
