我最近更新了我的一个(开源)Android应用程序,我的用户正在获得一个我无法复制的例外.关键部分是:

android.database.sqlite.SQLiteDatabaseLockedException: database is locked (code 5)

然后

Caused by: android.database.sqlite.SQLiteException: Failed to change locale for db '/data/data/com.airlocksoftware.hackernews/databases/hacker_news_cache.db' to 'en_US'.

这种情况发生在使用Android 2.3 - 4.2.1的设备上,并且在我尝试连接数据库的应用程序中的多个位置.我使用它后关闭数据库.

我找不到有关"未能更改db语言环境"异常的更多信息.当我查看SQLiteConnection的源代码(第386行)时,它似乎是'android_metadata'表或'使用新的语言环境更新索引'的问题.

这是导致异常的代码(在Github上).

我认为IntelliJ在生成R.java文件时存在一些问题,导致AndroidAnnotations出现问题,因为它无法解析布局的资源ID.

这是我的活动:

package com.airlocksoftware.canvastest;

import android.app.Activity;
import android.os.Bundle;
import com.googlecode.androidannotations.annotations.EActivity;

@EActivity(R.layout.main)
public class MyActivity extends Activity {
    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

奇怪的是,即使我注释掉注释,并且确实如此setContentView(R.layout.main),即使从未导入R.java,它也能正常工作.

顺便说一句,布局只是一个简单的"Hello World".没有什么奇怪的事情发生在那里.

无论我做什么,我都无法生成AndroidAnnotations CanvasActivity_.java.我的pom.xml看起来像这样:
