hi, all
I am porting android to loongson2f, when the System Server bring up the
Account Manager
Service, the System Service process was terminated by signal 11, by adding
log to the source code,
I found it died in the JNI C code, following is the calling stack:
> ServerThread:run
> PowerManagerService()
> validateAccounts()
> DatabaseHelper::getWritableDatabase()
> SQLiteOpenHelper::getWritableDatabase()
> ContextImpl::openOrCreateDatabase()
> SQLiteDatabase.openOrCreateDatabase()
> SQLiteDatabase.openDatabase()
> SQLiteDatabase() //Constructor
> dbopen() //JNI C code implemented
> in "frameworks\base\core\jni\android_database_SQLiteDatabase.cpp
>
I am sure the System Service died in the dbopen code as I called the Log.i
function millions time
before the dbopen, log are all printed correctly, and I also added the
following the code at the
end of dbopen function:
> for(int i=0; i<1000; i++)
> {
> fprintf(fp, "dbopen %d\n", i);
> fflush(fp);
> }
>
not all logs are recored, if I removes the for loop at the end of dbopen
function, the system will die some statement after the dbopen call, so, I
think the system died in this function, but I don't known how to fix it,
did it have to do with the JNI system?
any suggestion or tips will be appreciated!
thanks!
Best Regards
