Audiomanager has this method: Iswiredheadseton (); Returns true if the headset is inserted, otherwise false; Of course, to add a permission, or always return false. I started chasing after a long time source code. The process of detecting headphone inserts and unplugging was found in real time, but not very helpful to my needs. Real-time detection of headphone insertion and pull-out: Every time you insert and unplug headphones, the system sends intent

The example in this article describes the insert into data insertion usage of php+mysql. Share to everyone for your reference. Specifically as follows: The INSERT INTO statement is used to insert a new record into a database table. Inserting data into a database table The INSERT into statement is used to add a new record to a database table. Grammar: INSERT into table_name VALUES (value1, value2,....) You can also specify the column

Recording and playback in the development process there are a number of problems, the main problem is three: detect whether there is a sound input device when there are multiple sound output devices, the specified sound output device detects the insertion and pull-out of headphones First, for devices such as itouch and the ipad that do not have a microphone, you need to check to see if the headset is plugged in and it's relatively easy for the iphone

The day before yesterday finished the work at hand, the manager gave me a bug let me see, I took a look at the bug information, is never seen the exception, but according to the exception information prompts and very easy to determine the reason for the exception. Exception information: the incoming table format data stream (TDS) Remote Procedure Call (RPC) protocol stream is incorrect.

Statement or command mysqladmin flush-tables. 3). Use Myisamchk--keys-used=0-rq/path/to/db/tbl_name. This cancels the use of all indexes from the table. 4. Insert data into the table with the load data infile because no indexes are updated, so it is very quick. 5. If you only want to read the table at a later time, use Myisampack to compress it. See section 15.1.3.3, "Compress table attributes." 6) Re-create the index with Myisamchk-r-q/path/to/db/tbl_name. This creates an index tree in memory

inconvenient.5. The advantages of GUID: High efficiency, convenient data import and export, the disadvantage occupies a large space, difficult to read.6. The industry mainstream tends to use GUIDs.third, data insertion1. The INSERT statement can save the column name after the token name, but is not recommended.2. If the values of some fields in the inserted row are indeterminate, then insert does not specify those columns.(1)(2)3. You can set a default value for the field, which is automaticall
