我最近不得不参加一个项目并修复崩溃。崩溃发生在doInBackground上，AsyncTask通过调用：
来触发 public static void getCurrentUser(final UserDBInterface listener) {
new GetCurrentUserAsyncTask(listener).execute();
}
调用AsyncTask。
public class GetCurrentUserAsyncTask extends AsyncTask<String, Void, User> {
private UserDBInterface listener;
public GetCurrentUserAsyncTask(final UserDBInterface listener) {
this.listener = listener;
}
protected User doInBackground(final String... strings) {
return DatabaseHelper.getCurrentUser();
}
protected void onPostExecute(final User result) {
listener.onCurrentUserReady(result);
}
}
GetCurrentUser方法：
public static User getCurrentUser() {
final TotemSharedPreferences totemSharedPreferences = new TotemSharedPreferences();
final List<User> users = Select.from(User.class).where(DatabaseHelper.REMOTE_ID_LABEL + " = " + totemSharedPreferences.getUserId()).list();
if (!users.isEmpty()) {
final User mUser = users.get(0);
mUser.setUserBadge(DatabaseHelper.getAllUserBadges(mUser.getUserId()));
mUser.setKudosReceived(DatabaseHelper.getAllUserReceivedKudos(mUser.getUserId()));
mUser.setTeam(DatabaseHelper.getTeam(mUser.getTeamId()));
mUser.setCompany(DatabaseHelper.getCompany());
mUser.setStartedOn(new DateTime(mUser.getStartedOnString()));
mUser.setUserTeams(getAllUserTeams(mUser.getUserId()));
for (final UserTeam mUserTeam : mUser.getUserTeams())
if (mUserTeam.getRemoteId() == mUser.getActiveUserTeamId())
mUser.setKudosFund(mUserTeam.getKudosFund());
return mUser;
} else
return totemSharedPreferences.getUser();
}
用户类：
public class User extends SugarRecord {
@Column(name = "username")

@SerializedName("username")

我实际上刚开始进行android开发 - 我是一名iOS开发人员而且不习惯AsyncTasks。有人知道问题的根本原因吗？这些是我拥有的唯一日志：

我知道我被投了很多，但基本上答案是Sugar DB会自动向Databse添加列并且文档错误。更改表时无需执行迁移。我从2.sql，3.sql等中删除了SQL，只是将它们留空了。如果你必须更改列的名称等，只在那里插入东西。
答案 1 :(得分：0)
这可能是因为＆＃34; onUpgrade＆＃34;调用倍数倍。所以你需要检查以下内容。
提供适当的数据库版本并传递给DatabaseHelper构造函数
public DatabaseHelper(Context aContext) {
super(aContext, databaseName, null, databaseVersion);
}
在onUpgrade中检查正确的代码。
public void onUpgrade(SQLiteDatabase db, int oldVersion , int newVersion) {
if (oldVersion != DATABASE_VERSION) {
updateTablesUSERTEAM(db);
}
}
转到设置 - ＆gt;应用 - ＆gt;找到你的申请 - ＆gt;明确数据
重新运行您的代码。
