Where MMS and files are stored in Android. Where are SMS on Android? Where mms messages are stored in android

There are many applications that easily create messages backup or import saved copies back to the phone. But in SMS notifications there may be important personal information that I would not like to trust programs from third-party developer. Therefore, try to pull out files manually. To do this, you need to know where the SMS is stored on Android.

Access to SMS.

Directory that contains a file with MMS and SMS:

/data/data/com.android.providers.telephony/ databases / mmssms.db

The problem is that this file Stored in the secure memory of the Android OS. Alas, but without availability root right Or ADB Shell, you will not fall into this directory.

Export and Import SMS manually

Having superuser rights, you can save SMS to a memory card using special UNIX commands. To execute the command data, the Android terminal emulator and the BusyBox application will be required. From the BUSYBOX submitted commands, use the copy command.

Export:

$ cp /data/data/com.android.providers.telephony/ databases / mmssms.db / sdcard /

Import:

$ cp /ssdcard/mmssms.db /data/data/com.android.providers.telephony/ databases / mmssms.db

$ Chown Radio: Radio /Data/Data/com.android.providers.telephony/ Databases / MMSSMS.db

$ chmod 660 /data/data/com.android.providers.telephony/ databases / mmssms.db

Space Before databases /not needed.

The user in the terminology of specifications) is software On the side of the subscriber, which allows you to receive, send, view and handle multimedia content on the mobile terminal.

For communication exchange environments (it is difficult to choose the Russian analogue of the British terminology of Exchange), a user of services that sends and generates multimedia content, called the source (Originator), while the user of services that receives sent content - recipient (recipient).

In order to be able to send a message to the Subscriber, it is necessary to know its current location (for example, serving), so the MMSC is also connected to.

MMSC is also responsible for temporary storage (Cache Mode) or permanent posting messages (providing MMBOX for subscribers).

Consider in more detail, that part, and specifically the MMSC (see Figure below), which is associated with the storage of messages.

In order to determine the storage options for multimedia messages on the MMSC side, you need to look at the existing delivery mechanisms in more detail.

According to the specification, there is a so-called. Immediate (Immediate) and Deferred (Deferred) Sending MMS messages, which is defined on the recipient side. Immediate sending message is similar to the message delivery mechanism to the recipient, i.e. Messages are delivered immediately after it is sent, but in the case of its content can reach significant sizes and the recipient may not be able to process it (it does not have enough memory for storing the message). In addition, this mechanism opens wide opportunities For spammers, to deliver obsessive content to the recipient. To avoid such situations in the specification, the possibility of differentiated or delayed shipment was made, the mechanism of which consists of two stages:

1. MMSC temporarily saves (starting from the MMS version 1.0) message for the recipient in the temporary storage - Temporary Message Store and creates a kind of notification for the recipient, in which the characteristics of the message (size, type, etc.) specifies.
2. MMSC reports to the recipient that a certain message has come for him with the help of the created notice, and the recipient already "decides" whether he should take the specified content immediately or a little later, based on its capabilities.

In the case of these two methods, the recipient has the right to use the following mechanisms with respect to the transmitted message:

1. Rejection of the Message - Reject message reception.
2. Forward of the Message - redirect the message to the remote mailboxor to the address of another recipient.

Starting with version 1.2, the user is given the opportunity to store communication in the so-called. Multimedia Message Boxes ( MMBOX.) - in the network storage (Permanent Message Store) on the MMSC side. Using MMBOX, a user can:

• store sent / accepted multimedia messages;
• request messages from the repository;
• save messages that were redirected to other recipients;
• download / delete / view already saved messages;
• redirect messages from the repository, to other users;

Actually, with the help of such mechanisms, my multimedia messages can be stored, which I transmit or get to my mobile device.

Another pretty interesting opportunity to send messages, in my opinion, is so-called. Answer payment that allows the sender to pay all the answers to its sent message from the recipient (-th), specifying several conditions that must be executed by the recipient (-lm) \u200b\u200bto pay for the response message. These conditions can be:

1. the deadline for the response - the sender of the message may indicate that the response message will not be paid in the event that the answer will be sent later than the specified deadline.
2. response size - message sender can set maximum size response message if the answer is more specified sizeHe can be delivered to the sender of the message, but will not be paid for them.

But this is a completely different story ...
