hi, all
by further debuging, I found this problem was cased by calling
sqlite3_open_v2(path8, &handle, sqliteFlags, NULL) function in dbopen
of frameworks\base\core\jni\android_database_SQLiteDatabase.cpp file,
it not crash directly in the sqlite3_open_v2 function, but died some
where
after calling sqlite3_open_v2, if I replaced the sqlite3_open_v2
function with the following code:
for(int i=0;i<10000000;i++)
LOGI("useless code");
process will not die in the for loop at least, so I think the
sqlite3_open_v2 function is the evil, but I do not know what to do
next!
BTW, the linux kernel is 64bit and android filesystem is 32bit, did it
affect?
