问题 I'm working on an Android App that use SQLCipher , ORMLite for Android to handle to POJO storing with SQLite and Jackson for parsing.

How could I generalize using a generic class? Here

ORMLite - Parenthesis in join where clauses

由 百般思念 提交于 2019-12-07 18:52:15
问题 I would like to join three tables using QueryBuilder.join and QueryBuilder.joinor but I want parenthesis in the where clause something like this: WHERE first_table_where AND (second_table_where OR third_table_where) but it seems that is not possible. Perhaps I am missing something. Any help would be appreciated. 回答1: I guess that is a part of the doc you have been looking for... If you want to do complex queries linearly, you can even use Reverse Polish Notation (of all things). There is a

(Gradle and OrmLite config) How to add resource file after Java has been compiled but before .apk is generated?

由 ﹥＞﹥吖頭↗ 提交于 2019-12-07 09:56:56
问题 NOTE: I have already accepted an answer and awarded the bounty, BUT, have in the end decided that my approach to this issue was far from optimal. After further thought I have come to the conclusion that modifying the .apk during the build process is probably not the safest or most sustainable way to accomplish this and keep it working long term. I have added an alternative approach to the very bottom of this question, which accomplishes the same thing in the end. This approach I opted to use

Releasing ORMLite helper on @Singleton

由 大城市里の小女人 提交于 2019-12-07 07:23:51
问题 I have a @Singleton class where I've injected an instance of OrmLiteSqliteOpenHelper . Do I actually ever need to call the OpenHelperManager.releaseHelper() ? In case I do, where and how should it be done as the class doesn't extend any Android base class where I could get to the onDestroy ? 回答1: There is an ORMLite example Android project which demonstrates this called HelloAndroidNoBase. I'd check it out. The relevant code section from the main Activity is included below. You'll need to

由 纵饮孤独 提交于 2019-12-07 06:13:48
问题 I have a few models that I want to obfuscate in my code. I know that I could just ignore the whole model package but I don't want to do that. I tried a few proguard tweaks and checked all relevant posts to no avail. ORMlite keeps throwing java.lang.RuntimeException: Unable to create application ...App: java.lang.IllegalArgumentException: Foreign field class ....f.p does not have id field . I checked that the annotation is still there with dex2jar and jd, and it is still there. I have this

Ormlite Android bulk inserts

由 こ雲淡風輕ζ 提交于 2019-12-06 22:35:23
问题 can anyone explain why my inserts are taking so long in Ormlite? Doing 1,700 inserts in one sqlite transaction on the desktop takes less than a second. However, when using Ormlite for Android, it's taking about 70 seconds, and I can see each insert in the debugging messages. When I try and wrap the inserts into one transaction it goes at exactly the same speed. I understand that there is overhead both for Android and for Ormlite, however, I wouldn't expect it to be that great. My code is
