I am making and application that records calls. Here is my code to record a call and save the file in the SD card under songs folder. But the problem is that this code was working fine but later it is not working. I cannot find what is the problem. Can you please help me out?
My Broad cast receiver:
public class BrCallReceive extends BroadcastReceiver {
#Override
public void onReceive(Context c, Intent i) {
Bundle extras = i.getExtras();
Intent x = new Intent (c, EavesDropperActivity.class);
x.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("DEBUG", state);
if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
Log.w("DEBUG", "MATCHES");
Toast.makeText(c, "Launching record APP !", Toast.LENGTH_LONG).show();
c.startActivity(x);
}
}
}
}
My Recording activity:
public class EavesDropperActivity extends Activity {
/** Called when the activity is first created. */
MediaRecorder m_recorder = new MediaRecorder();
TelephonyManager t_manager ;
PhoneStateListener p_listener ;

Uri file;
#Override

t_manager = (TelephonyManager) getSystemService (Context.TELEPHONY_SERVICE);
p_listener = new PhoneStateListener() {
#Override
public void onCallStateChanged (int state, String incomingNumber) {
switch (state) {
case (TelephonyManager.CALL_STATE_IDLE) :
stop_recorder();
//t_manager.listen(p_listener, PhoneStateListener.LISTEN_NONE);
//finish();
break;
case (TelephonyManager.CALL_STATE_OFFHOOK) :
start_recorder();
break;
case (TelephonyManager.CALL_STATE_RINGING) :
break;
}
}
};
t_manager.listen(p_listener, PhoneStateListener.LISTEN_CALL_STATE);
return;
}
public void start_recorder () {
m_recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
m_recorder.setOutputFormat(OutputFormat.THREE_GPP);
m_recorder.setOutputFile(Environment.getExternalStorageDirectory()+"/songs/audionew.3gpp");
m_recorder.setAudioEncoder(AudioEncoder.AMR_NB);

I think the broadcast receiver is not getting activated wile i am calling my phone.
How do you know your broadcast receiver is not working? Place a Log message inside onReceive() right at the beginning. It might be that your extras == null
But how to make my receiver functional now?
Check out example #5 and just follow the same steps.
Bro i dont think activity will get launched.
Well, it does: You are starting it in your onReceive():
Intent x = new Intent (c, EavesDropperActivity.class);
c.startActivity(x);
However, you are not setting any content in your Activity i.e no UI screen is presented because you have this line commented in onCreate() of EavesDropperActivity Activity:
//setContentView(R.layout.main);
So, you need to think hard on what you are trying to achieve in EavesDropperActivity
HTH.
Put this
<android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
in mainfest file for broadcast receiver.
Add your package name to your receiver class as,
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testapp"
android:versionCode="1"
android:versionName="1.0" >

I am trying to do some work at incoming call times. I am trying like this
public class callDeductor extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
Toast.makeText(context, "Phone Is Ringing", Toast.LENGTH_LONG).show();
}
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))

Toast.makeText(context, "Call Recieved", Toast.LENGTH_LONG).show();
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
Toast.makeText(context, "Phone Is Idle", Toast.LENGTH_LONG).show();
}
}
}
This is my Manifeast:
<?xml version="1.0" encoding="utf-8"?>

Continuing my conversation with asker as an answer.I Just started a new Android application and worked out like i have said in the comments.. The manifest looks like this :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dj.randomtest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".CallDetector">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
The CallDetector class looks like this(ur code):
public class CallDetector extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
Toast.makeText(context, "Phone Is Ringing", Toast.LENGTH_LONG).show();
}
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
Toast.makeText(context, "Call Recieved", Toast.LENGTH_LONG).show();
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
Toast.makeText(context, "Phone Is Idle", Toast.LENGTH_LONG).show();
}
}
}

Really Appreciate the help. Thanks!!
you need to declare permission in your manifest
<permission
android:name="com.example.yamba.permission.REFRESH"
android:protectionLevel="signature"
/>
You need to declare this REFRESH Permission in the manifest as well.
here is an example code of how to declare a permission
<permission
android:name="A_PERMISSION"
android:description="#string/broadcast_permission_desc"
android:label="#string/broadcast_permission_label"
android:permissionGroup="#string/broadcast_permission_group"
android:protectionLevel="signature" />

I am Creating incoming call Receive activity by SipDemo . My activity has two button "accept call" and "reject call". When i got incoming call then my own activity is open such as
----> incoming call class ----> onReceive()----> go to my call pick activity.
here is this above two button such as accept and reject call. but when i hit on "accept call" . A Nullpointer Exception generate. it is on SipAudiocall incoming;
this is incoming class:-
static SipAudioCall incomingCall = null;
#Override
public void onReceive(final Context context, Intent intent) {
Intent startActivity = new Intent();
startActivity.setClass(context, Mycall.class);
startActivity.setAction(IncomingCallReceiver.class.getName());
startActivity.setFlags(
Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
context.startActivity(startActivity);
}
public static void acceptCall() {
incomingCall.sendDtmf(9);
try {
incomingCall.sendDtmf(9);
incomingCall.answerCall(200);
//wtActivity.gototimer("i");
} catch (SipException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// wtActivity.gototimer("i");
}
public void rejectCaLL() {
try {
incomingCall.endCall();
} catch (SipException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
This is my call pick activity class:-
public class Mycall extends Activity {
Button acct;
IncomingCallReceiver incomingCallReceiver;
#Override
public void onCreate(Bundle savedInstanceState) {
// Note that none of the preferences are actually defined here.
// They're all in the XML file res/xml/preferences.xml.
super.onCreate(savedInstanceState);
setContentView(R.layout.my);
acct = (Button) findViewById(R.id.button1);
acct.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
IncomingCallReceiver.acceptCall();
}
});
}
}

Please Expert Help me. I has involved this problem since 1 month.
I am wait for your response.
Thank you
Becouse your
IncomingCallReceiver incomingCallReceiver;
is null at time of calling it...
If you create a static class you must take care to initiate it maybe in creator-method.
create an abstract class:
public abstract class IncomingCallReceiver
and change your method to public static final
I have a BroadcastReceiver and I know how to reject calls. But I need help rejecting a call when I press the back button, because I have some sort of error in my code...

public Intent i;
#Override
public void onReceive(Context context, Intent intent) {

String state = extras.getString(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
phoneNumber = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast toast= Toast.makeText(context,phoneNumber, Toast.LENGTH_LONG);toast.show();
tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
try {
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");

as far as I know you cant use the backbutton onreceive event that u are using to decline call, but the back button press function i ok and it should work if you use it other than in the broadcast receive onReceive
I am trying to send an Intent from the onCreate in an Activity to start an IntentService. However the IntentService's onHandleIntent is never being received. I have tried changing around the Manifest with Intent-filters but nothing seems to be working. No exceptions are being thrown, but the IntentService is simply not called.
Here is the onCreate
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
db = new TwitterDB(this);
String[] columns = new String[1];
columns[0] = TwitterDB.TEXT;
tAdapter = new SimpleCursorAdapter(this, 0, null, columns, null, 0);
tweets = (ListView)findViewById(R.id.listtwitter);
tweets.setAdapter(tAdapter);
Intent intent = new Intent(this, SyncService.class);
intent.putExtra("action", SyncService.TWITTER_SYNC);
this.startService(intent);
}
Here is the creator and onHandleIntent of the IntentService class, I know it is not being called because logcat never shows "Retrieved intent". The constructor is not called either (There was a log call in there, but I removed it.
public SyncService(){
super("SyncService");
twitterURI = Uri.parse(TWITTER_URI);
Log.i("SyncService", "Constructed");
}
#Override
public void onHandleIntent(Intent i){
int action = i.getIntExtra("action", -1);
Log.i("SyncService", "Retrieved intent");
switch (action){
case TWITTER_SYNC:
try{
url = new URL(twitterString);
conn = (HttpURLConnection)url.openConnection();
syncTwitterDB();
conn.disconnect();
}catch(MalformedURLException e){
Log.w("SyncService", "Twitter URL is no longer valid.");
e.printStackTrace();
}catch(IOException e){
Log.w("SyncService", "Twitter connection could not be established.");
e.printStackTrace();
}
break;
default:;
// invalid request
}
}
And here is the Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<service android:name="SyncService"/>
</activity>
</application>
</manifest>
Move your service declaration outside of the scope of the TwitterTwoActivity in the XML file, as I have done here:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twitter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".TwitterTwoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="SyncService"/>
</application>
</manifest>
You need to define the path to the service in your manifest, simply putting the name is not sufficient.
Change
<service android:name="SyncService"/>
to
<service android:name=".SyncService"/>
if SyncService is in the root of your package, add respective folder before .SyncService if needed.
