数据库处理在 Android 2.2.1 (Desire HD 1.72.405.3) 上停止工作 [英] Database handling stopped working on Android 2.2.1 (Desire HD 1.72.405.3)

问题描述

出于某种原因，这篇文章 无法在 HTC Desire HD 上使用 OTA 更新到 2.2.1 (1.72.405.3) 后.它在更新之前在 Desire HD 上运行，但我未能在运行 2.1、2.2 的实际设备以及运行所有版本的模拟器上重现该错误.

For some reason the database handling solution described in this article doesn't work on the HTC Desire HD after it got the OTA update to 2.2.1 (1.72.405.3). It worked on Desire HD before the update and I've failed to reproduce the error on actual devices running 2.1, 2.2 as well as in emulator running all versions.

不幸的是，您无法为运行 Android 2.2.1 的模拟器创建 AVD，我尝试过基于 2.2.1 的 ROM(我有一个普通的 HTC Desire)，但我的应用程序在它上面也没有问题.所以问题是，如果它以某种方式使用 Android SDK，它不应该突然导致问题吗?

Unfortunately you can't created a AVD for emulator running Android 2.2.1 and I've tried a ROM based on 2.2.1 (I have a rooted ordinary HTC Desire) but my application works without problem on it as well. So the question is if it's using the Android SDK in some way it shouldn't that all of a sudden cause the problem?

我知道这是一个非常具体的问题，但由于报告问题的开发人员比我多，而且您无法创建 AVD，我希望这个问题被接受，我希望有人知道可能导致问题.

I know this is a very specific issue but since more developers than me reporting the problem as well as the fact that you can't create an AVD I hope the question is accepted and I hope someone have a clue what might causing the problem.

推荐答案

我的应用似乎终于可以在 Desire HD 上的 Android 2.2.1 上运行了.我还没有机会亲自调试它以尝试确切地导致问题的原因.

I finally seem to have got my app to work on Android 2.2.1 on Desire HD. I haven’t had the chance to debug on it personally to try out exactly what’s causing the problem.

弹出的一个想法是数据库文件所在位置的硬编码路径.DB_PATH = /data/data/YOUR_PACKAGE/databases/";

One thought that popped up is the hard coded path to where the database file is located. DB_PATH = "/data/data/YOUR_PACKAGE/databases/";

我想这个路径可能在 Android 2.2.1 for Desire HD 上无效.我交换了这条路径:Environment.getDataDirectory() + /data/YOUR_PACKAGE/databases/" + DB_NAME;

I guess it is possible that this path isn’t valid on Android 2.2.1 for Desire HD. I exchanged this path with: Environment.getDataDirectory() + "/data/YOUR_PACKAGE/databases/" + DB_NAME;

当我有机会亲自在实际手机上进行测试时，我会尝试找出问题所在.如果有人测试此解决方案，请告诉我它是否解决了问题.

I’ll try to pin point the issue when I had the chance to test on the actual phone myself. If anyone test this solution, please let me know if it solves it.
