我想在heruko上使用parse.com解析服务器开发一个新的Android应用程序。我按照所有正确的步骤将解析服务器部署到heruko，当我测试应用程序时它崩溃了，我得到一个零点异常这里是我的代码
package com.example.machimanapc.starterapplication;
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseACL;
import com.parse.ParseUser;
public class StarterApplication extends Application {
@Override
public void onCreate() {
// Enable Local Datastore.
Parse.enableLocalDatastore(this);
String app_id = getResources().getString(R.string.parse_app_id);
String client_key = getResources().getString(R.string.parse_client_key);
String server = getResources().getString(R.string.parse_server);
// Add your initialization code here
Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
.applicationId(app_id).clientKey(client_key).server(server).build());
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
// Optionally enable public read access.
// defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
}
}
Main Activity
package com.example.machimanapc.starterapplication;
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseACL;
import com.parse.ParseUser;
public class StarterApplication extends Application {
@Override
public void onCreate() {
// Enable Local Datastore.
Parse.enableLocalDatastore(this);
String app_id = getResources().getString(R.string.parse_app_id);
String client_key = getResources().getString(R.string.parse_client_key);
String server = getResources().getString(R.string.parse_server);
// Add your initialization code here
Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
.applicationId(app_id).clientKey(client_key).server(server).build());
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
// Optionally enable public read access.
// defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
}

super.onCreate();
OneSignal.startInit(this)
.inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
.init();
Parse.enableLocalDatastore(this);
Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
.applicationId("TYPE_IN_YOUR_APP_ID")
.clientKey("TYPE_IN_YOUR_CLIENT_KEY")
.server("https://MY_HEROKU_URL.com/parse/")
.build()
);

ParseACL defaultACL = new ParseACL();
// Optionally enable public read access.
// defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
