Develop Reference

Record call even after my app is closed and cleared from recents

I am developing an Android application, where I have asked to implement the call record ,I have gone through SO and found One Solution which is working fine when my app is opened. If I close my app or clear it from recent apps, Call record is not working. Tried searching in the Google and SO but no luck. I am posting my code here, Can some one help me in getting the solution.

any help would be grateful!!!
Thanks in advance!!

use START_STICKY as return param of onStartCommand() so when you kill you app it will restart the service
for reference you can check android developer guide

You are getting the exception because in class ObdGatewayService your class member mChatservice is not the same as mChatservice in class LiveFragment
They are just different member variables
mChatservice gets assigned like this in your Fragment
mChatService = new BluetoothChatService(getActivity(), mHandler);
You need to pass this reference to ObdGatewayService 's startService() like this where ever you are instantiating/invoking it:-
ObdGatewayService ogs;
....
ogs.startservice(mChatservice); // This is fragment's member reference
And in ObdGatewayService you have to assign it accordingly:-
public void startService(BluetoothChatService _mChatservice) throws IOException {
Log.d(TAG, "Starting service..");
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
mChatservice = _mChatservice //Assignment YOU ARE MISSING THIS
.......
.......

I am new to android.I have seen many examples.but all doesn't help me.I want example or tutorial for How to Record incoming and outgoing calls in android.can anyone refer good tutorial for this?

Ok, for this first of all you need to use Device Policy Manager, and need to make your device Admin device. After that you have to create one BroadCaast receiver and one service. I am posting code here and its working fine.
MainActivity:
public class MainActivity extends Activity {
private static final int REQUEST_CODE = 0;
private DevicePolicyManager mDPM;
private ComponentName mAdminName;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Initiate DevicePolicyManager.
mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
mAdminName = new ComponentName(this, DeviceAdminDemo.class);
if (!mDPM.isAdminActive(mAdminName)) {
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Click on Activate button to secure your application.");
startActivityForResult(intent, REQUEST_CODE);
} else {
// mDPM.lockNow();
// Intent intent = new Intent(MainActivity.this,

// startService(intent);
}
} catch (Exception e) {
e.printStackTrace();
}
}

well you could use an android app called Call Recorder from Google Play
Call Recorder
i've never tried it before but it was the first link in go*gle
good luck with that.

Application not responding error

I have a tracking app that does tracking based on gps and cell id at every 2 minutes. I have started a service from MainActivity using setRepeting() of AlarmManager. Then inside that service I have written an asynctask.In onPreExecute() I fetch latitude and longitude using gps or cellid. And in doInBackground() i am fetching data from sqlite db and send to server. Even after writing all network related code in asynctask app sometimes says application not responding. and on pressing ok it restart. What can I do to avoid this.

You should be fetching the lat and long in the doInBackground() method, and not in preExecute().
Fetching the location might take some time, and should be done in the background. That is why you have this problem.

How to record phone calls in android?

I want to make an app which records the incoming and outgoing calls and it run automatically when user get or make any call.

Ok, for this first of all you need to use Device Policy Manager, and need to make your device Admin device. After that you have to create one BroadCast receiver and one service. I am posting code here and its working fine.
MainActivity:
public class MainActivity extends Activity {
private static final int REQUEST_CODE = 0;
private DevicePolicyManager mDPM;
private ComponentName mAdminName;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Initiate DevicePolicyManager.
mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
mAdminName = new ComponentName(this, DeviceAdminDemo.class);
if (!mDPM.isAdminActive(mAdminName)) {
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Click on Activate button to secure your application.");
startActivityForResult(intent, REQUEST_CODE);
} else {
// mDPM.lockNow();
// Intent intent = new Intent(MainActivity.this,
// TrackDeviceService.class);
// startService(intent);
}
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (REQUEST_CODE == requestCode) {
Intent intent = new Intent(MainActivity.this, TService.class);
startService(intent);
}
}
}
//DeviceAdminDemo class
public class DeviceAdminDemo extends DeviceAdminReceiver {
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);

So, basically, I want to combine 2 answers, one from this post and one from another post that I read, don't know the author of it so please sorry for using your methods.
So, here are my classes for achieving desired result:

}
inside TService class you will find CallReceiever class that is going to handle everything you need from the call. You can add parameters as per your will, but, the main point is important.
From your MainActvitiy call Service that will start your Receiever. If you want to record media from receiever directly, you will get errors, so, you need to register Receiever from service. After that, you can call start recording and end recording wherever you like.
Calling return super.onStartCommand(intent, flags, startId); will have that Service lasting for more than one call, so keep that in mind.
Finally, AndroidManifest.xml file:
<manifest

So, this is it, it's working perfectly with my Samsung Galaxy s6 Edge+, Ive tested it on Galaxy Note 4 and on Samsung J5, a big thank you to the authors of this post and the post about receiving phone calls.

The accepted answer is perfect, except it does not record outgoing calls. Note that for outgoing calls it is not possible (as near as I can tell from scouring many posts) to detect when the call is actually answered (if anybody can find a way other than scouring notifications or logs please let me know). The easiest solution is to just start recording straight away when the outgoing call is placed and stop recording when IDLE is detected. Just adding the same class as above with outgoing recording in this manner for completeness:
private void startRecord(String seed) {
String out = new SimpleDateFormat("dd-MM-yyyy hh-mm-ss").format(new Date());
File sampleDir = new File(Environment.getExternalStorageDirectory(), "/TestRecordingDasa1");
if (!sampleDir.exists()) {
sampleDir.mkdirs();
}
String file_name = "Record" + seed;
try {
audiofile = File.createTempFile(file_name, ".amr", sampleDir);
} catch (IOException e) {
e.printStackTrace();
}
String path = Environment.getExternalStorageDirectory().getAbsolutePath();
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION);
recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(audiofile.getAbsolutePath());
try {
recorder.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
recorder.start();
recordstarted = true;
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_IN)) {
if ((bundle = intent.getExtras()) != null) {
state = bundle.getString(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
inCall = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
wasRinging = true;
Toast.makeText(context, "IN : " + inCall, Toast.LENGTH_LONG).show();
} else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
if (wasRinging == true) {
Toast.makeText(context, "ANSWERED", Toast.LENGTH_LONG).show();
startRecord("incoming");
}
} else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
wasRinging = false;
Toast.makeText(context, "REJECT || DISCO", Toast.LENGTH_LONG).show();
if (recordstarted) {
recorder.stop();
recordstarted = false;
}
}
}
} else if (intent.getAction().equals(ACTION_OUT)) {
if ((bundle = intent.getExtras()) != null) {
outCall = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Toast.makeText(context, "OUT : " + outCall, Toast.LENGTH_LONG).show();
startRecord("outgoing");
if ((bundle = intent.getExtras()) != null) {
state = bundle.getString(TelephonyManager.EXTRA_STATE);
if (state != null) {
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {

The answer of pratt is bit uncomplete, because when you restart your device your app will working stop, recording stop, its become useless.
i m adding some line that copy in your project for complete working of Pratt answer.
<receiver
android:name=".DeviceAdminDemo"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data
android:name="android.app.admin"
android:resource="#xml/device_admin" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
<action android:name="android.app.action.DEVICE_ADMIN_DISABLED" />
<action android:name="android.app.action.DEVICE_ADMIN_DISABLE_REQUESTED" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
put this code in onReceive of DeviceAdminDemo
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
context.stopService(new Intent(context, TService.class));
Intent myIntent = new Intent(context, TService.class);
context.startService(myIntent);
}

There is a simple solution to this problem using this library. I store an instance of the CallRecord class in MyService.class. When the service is first initialized, the following code is executed:
public class MyService extends Service {
public static CallRecord callRecord;
#Override
public void onCreate() {
super.onCreate();
callRecord = new CallRecord.Builder(this)
.setRecordFileName("test")
.setRecordDirName("Download")
.setRecordDirPath(Environment.getExternalStorageDirectory().getPath()) // optional & default value
.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB) // optional & default value
.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB) // optional & default value
.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION) // optional & default value
.setShowSeed(false) // optional, default=true ->Ex: RecordFileName_incoming.amr || RecordFileName_outgoing.amr
.build();
callRecord.enableSaveFile();
callRecord.startCallReceiver();
}
#Override
public void onDestroy() {
super.onDestroy();
callRecord.stopCallReceiver();

Next, do not forget to specify permissions in the manifest. (I may have some extras here, but keep in mind that some of them are necessary only for newer versions of Android)
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Also it is crucial to request some permissions at the first start of the application. A guide is provided here.
