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!
