【我的Android进阶之旅】解决sqlcipher库：java.lang.IllegalStateException: get field slot from row 0 col 0 failed.
一、背景
最近维护公司的大数据SDK，在大数据SDK里面加入了ANR的监控功能，并将ANR的相关信息通过大数据埋点的方式记录到了数据库中，然后大数据上报的时候上报到大数据平台，这样就可以实现ANR性能的监控功能。
但是，最近看友盟的大数据平台错误上， 有一个是调用大数据SDK上报时，查询数据库出现的异常，异常错误信息如下所示：
java.lang.IllegalStateException: get field slot from row 0 col 0 failed
at net.sqlcipher.CursorWindow.getString_native(Native Method)

这个异常一下子就出现了 348次，影响了6个用户，有一款机型出现了316次， 里面将整个app的整体奔溃率拉高了。简直要命啊！
二、分析问题
猜测一、大数据SDK版本没更新
开始我以为是大数据SDK更新删除字段，增加字段后，没有升级大数据的数据库版本。但是之前发布的APP引用的大数据SDK的数据库版本为3，而刚刚发布的APP的大数据SDK的数据库版本为4，整体上数据库升级了，应该是没有问题的。
猜测二 、数据库查询的单条记录超过1MB
一开始，完全找不到原因，只能靠各种猜测，各种google，百度答案。查询到的有参考一样的链接如下所示：
- https://stackoverflow.com/questions/5406429/cursor-size-limit-in-android-sqlitedatabase
- https://github.com/sqlcipher/android-database-sqlcipher/issues/341#issuecomment-310289295
其中有一段话，说的是
There’s a limit of 1MB on internal assets due to dynamic decompression; the 1MB limit also seems to apply to Cursor blobs but this doesn’t seem to be documented anywhere.
Generally you should avoid blobs in SQLite as they perform poorly; instead save the blob data as a file and store the location of the file in your DB.
1、分析抓取的日志
通过抓取到的日志信息来看，因为这个异常是发生在捕获到ANRException之后，触发了大数据SDK上报的操作而导致异常的。所以初步怀疑是ANR的堆栈信息太多导致查询数据库时候奔溃了。
2、一次性查询出来的多条信息超过1Mb是否会奔溃？
一开始我和另外一个同事进行压测，将拉取到的日志ANR异常日志的stackInfo循环500次插入数据库然后每200条取出来一次查询。这样一次性查询出来的多条信息查过了1Mb，但是完全没有奔溃一切正常。因此排除了一次性查询出来的多条信息超过1Mb是否会奔溃这个点。
3、一次性查询出来的单条信息超过1Mb是否会奔溃？
后来我又去测了一下，如果一条数据量超过1Mb会怎么样？测试结果是这个异常果断出现了。
测试方法如下：
点击某个按钮，执行下面的startTest() 方法，手动埋上一个ANRException,单挑的堆栈信息很大，测试代码是临时测试的。
private void startTest() {
new Thread() {
@Override
public void run() {
StringBuffer stack = new StringBuffer("[W][2018-01-30 +8.0 10:24:58.596][14396, 274][:][com.xtc.bigdata.monitor.anr.ANRMonitor, dumpBlockInfo, 48][stackTraceInfo:01-30 10:23:12.153\n" +

}
try {
Thread.sleep(300000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}.start();
}
然后果断的出现了异常，异常如下所示：
通过上面的测试，发现了这个crash的根本原因就是，单挑数据库的记录过大，导致查询的时候出现奔溃。
三、处理方法
3.1 将大数据SDK的ANR监控暂时屏蔽掉
,现有的ANR监控的堆栈信息太多，容易出问题。而且在我们进行压测的过程中，发现及时单条记录不超过1mb，但是多条记录过大的时候，http上报大数据的时候，http的请求的body过大也会导致请求失败，因此暂时将ANR监控的功能屏蔽掉。
3.2 对调用OrmLiteDao封装类的相关代码处加上 try/catch 处理
因为OrmLiteDao封装类里面，只捕获了SQL相关的异常，没有捕获其他类型的异常，所以出现的时候就会奔溃。
因为OrmLiteDao的封装类，我们在封装的时候只catch了sql操作习惯的异常，因此暂时在调用数据库操作的时候，在调用的地方加上 try/catch 捕获住刚才的IllegalStateException异常。
3.3 对 android-database-sqlcipher 进行升级
在 android-database-sqlcipher 这个项目中，
有人提了相同的Issue，链接如下所示：
https://github.com/sqlcipher/android-database-sqlcipher/issues/341#issuecomment-310289295 ，
通过查看Issue的描述，发现和我们的这个crash类似。
然后我们将 net.zetetic:android-database-sqlcipher 库进行了升级。
一开始我们项目引用的版本为： net.zetetic:android-database-sqlcipher:3.5.4
单条数据太大的时候，就会奔溃
升级为 net.zetetic:android-database-sqlcipher:3.5.9
升级完成之后，重新编译APP，然后重新进行压测，发现这个crash不存在了。
四、总结
- 不要在数据库中的单条数据插入太多的数据。
- 通过升级net.zetetic:android-database-sqlcipher版本到3.5.9可以修复这个1MB的限制。
五、参考链接
