我使用这个函数来检查数据库是否存在，它应该抛出错误，但它会抛出异常并导致我的应用程序崩溃，为什么会这样？
private boolean checkDataBase() {
SQLiteDatabase checkDB = null;
try {
checkDB = SQLiteDatabase.openDatabase(
"/data/data/com.pickante.app/databases/pickante", null,
SQLiteDatabase.OPEN_READONLY);
checkDB.close();
} catch (SQLiteException e) {
// database doesn't exist yet.
}
return checkDB != null ? true : false;
}
