Handling incoming call in android - android

In my app i want to detect incoming call and i want to hide default incoming call layout with my custom layout,far now i have managed to get the state of incoming call but i'm not able to hide the default incoming call screen...below is my code and my android manifest file...any help will be appreciated..
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.i("DEBUG", "on recive called");
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
if (TelephonyManager.EXTRA_STATE_RINGING.equals(state))
{
abortBroadcast();
Log.d("MPR", "Its Ringing [" + number + "]");
//start activity
Intent i = new Intent();
i.setClassName("com.ezest.callerid", "com.ezest.callerid.CustomCallActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
if (TelephonyManager.EXTRA_STATE_IDLE.equals(state))
{
Log.d("MPR", "Its Idle");
}
if (TelephonyManager.EXTRA_STATE_OFFHOOK.equals(state))
{
Log.d("MPR", "Its OffHook");
}
}
Manifest
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name="MYPhoneStateListener">
<intent-filter android:priority="999999">
<action android:name="android.intent.action.PHONE_STATE"></action>
</intent-filter>
</receiver>
<activity
android:label="#string/app_name"
android:name=".CallerIDActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="CustomCallActivity">
</activity>
</application>

when defined action is happened android operating system send broadcast to all defined broadcastreceiver for this action. it does this job according to priority order. I can see you have done it. copy that code where you want to cancel broadcast.
abortBroadcast()
Android operating system will stop broadcasting to other broadcastreceivers

Boot Complete Broadcast not Working

I am trying to start an activity when am restart my phone then its open app or show me toast when booting is complete
class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)) {
Intent serviceIntent = new Intent(context, MyIntentService.class);
context.startService(serviceIntent);
}
}
}
this is my Broadcaste receiver Code
class MyIntentService extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
// do something when the service is created
}
}
This is my service Code.
Manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>

am trying lots of diffrent code but no one work for me so can anyone help me to correct this code
Your BroadcastReceiver will never get called because you have this in the manifest entry for it:
android:exported="false"
Remove that.
NOTE: You also need to make sure that your app is started at least once manually after installing it on the phone. Otherwise your BroadcastReceiver will NOT get the BOOT_COMPLETE Intent.
NOTE: Also, using Toast as a debugging aid isn't a very good idea. You should write messages to the logcat and use that to determine if your Service is getting started, etc. Toast is not reliable as a debugging tool.
Add this in BroadcastReceiver class
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent pushIntent = new Intent(context, SyncData.class);
context.startService(pushIntent);
Log.e("BroadCast Received", "ON BOOT COMPLETE");
}
}
and remove this two lines android:enabled="true"
android:exported="false"

Two times power button clicking from the home screen after clearing the cache not working

I am building a app which will activated after two times clicking the power button. The things are going fine when I am doing that after opening the app. But when from the home screen trying to do so. Toast is activated but the activity which should also be opened did not opened. And also when the recent apps cleared then actually nothing worked.
Here are the broadcastreceiver file.
public class CloseSystemDialogsIntentReceiver extends BroadcastReceiver {
public static boolean wasScreenOn = true;
static long prevTime=0;
static long currTime=0;
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
// do whatever you need to do here
prevTime = System.currentTimeMillis();
Log.d("CHECK IN RECIVER WHEN ON","CHECK IN RECIVER WHEN ON");
wasScreenOn = false;
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
// and do whatever you need to do here
Log.d("CHECK IN RECIVER WHEN ON","CHECK IN RECIVER WHEN OFF");
currTime = System.currentTimeMillis();
wasScreenOn = true;
}
if ((currTime - prevTime) < 1000 && (currTime - prevTime)>-1000 ) {
if ((currTime - prevTime) < 1000 ) {
Toast.makeText(context, "double Clicked power button",
Toast.LENGTH_LONG).show();
Intent main=new Intent();
main.setClassName("com.example.speechto", "com.example.speechto.MainActivity");
main.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(main);
Log.e("eciver ", "double Clicked power button");
currTime = 0;
prevTime = 0;
}
}
}
}
and the manifest file contains
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.projpb1.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>
<activity
android:name="com.example.projpb1"
android:label="#string/title_activity_new" >
</activity>
<receiver android:name="com.example.projpb1.CloseSystemDialogsIntentReceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_OFF"></action>
<action android:name="android.intent.action.SCREEN_ON"></action>
<action android:name="android.intent.action.ACTION_POWER_CONNECTED"></action>
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED">
</action>
<action android:name="android.intent.action.ACTION_SHUTDOWN"></action>
</intent-filter>
</receiver>
</application>
</manifest>
You cannot register SCREEN_OFF or SCREEN_ON intents for a receiver in the manifest; you must register them dynamically, by creating an intent filter and registering a receiver in your activity or service at runtime.
// Add this to your Activity or Service
// Register a receiver for the screen state change
if (screenReceiver == null){
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
screenReceiver = new CloseSystemDialogsIntentReceiver();
registerReceiver(screenReceiver, filter);
}

How to make BroadcastReceiver work after reboot?

I have a written a program which intercepts incoming call using BroadcastReceiver. When I start my app, it starts working. Now the problem is when I restart my android phone, this BroadcastReceiver doesn't work. So I am assuming that I need to make a service for this. But I don't know when to start service and where to start BroadcastReceiver.
BroadcastReceiver code -
public class CallInterceptor extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Service started", Toast.LENGTH_LONG).show();
Bundle extras = intent.getExtras();
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Toast.makeText(context, "Phone is " + state, Toast.LENGTH_LONG).show();
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
String phoneNumber = extras
.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast.makeText(context, "Call from " + phoneNumber, Toast.LENGTH_LONG).show();
//sendSMS(phoneNumber);
//toggle ringer mode
AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
toggleMode(am);
}
}
}
AndroidManifest file -
<receiver android:name="com.nagarro.service.CallInterceptor" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" >
<action android:name="android.intent.action.BOOT_COMPLETED" />
</action>
</intent-filter>
</receiver>
I don't think <action android:name="android.intent.action.BOOT_COMPLETED" /> is working.
Also, is it possible to do this without service? Please suggest approach which will help me to intercept call evertime (even after reboot).
You've improperly closed your first action tag. Your receiver section should look like:
<receiver android:name="com.nagarro.service.CallInterceptor" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Also, you are not using a Service. You're using a Broadcast Receiver.
See this page for the basics Application Fundamentals.

To block the out going call from my android app.

I want to make an application in which once the application starts, it will show two button(start and stop button) and once the user clicks the start button the call function will be blocked for the time period till the user again start the application and click the stop button to stop this function. any help please its urgent
in short I Will tell I want to block the outgoing call from my phone by using this activity only
please is there any way to do so???
You can block the outgoing call using the setResultData(null) function in the onReceive method of the Broaadcast receiver.
public class BlockOutgoing extends BroadcastReceiver
{
String number;
#Override
public void onReceive(Context context, Intent intent)
{
Log.d("12280", "asdasNumber is-->> " + number);
number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
setResultData(null);
Toast.makeText(context, "Outgoing Call Blocked" , 5000).show();
}
}
In the manifest file, you need to register the receiver like this,
<receiver
android:name=".BlockOutgoing"
android:label="#string/app_name" >
<intent-filter android:priority="1">
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
Also define the permission to intercept the outgoing call,
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
Edit-
To unregister a broadcast receiver, follow this link
public class BlockOutgoing extends BroadcastReceiver {
String number;
#SuppressLint("WrongConstant")
#Override
public void onReceive(Context context, Intent intent)
{
// Log.d("12280", "asdasNumber is-->> " + number);
number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
setResultData(null);
Toast.makeText(context, "Outgoing Call Blocked" , 5000).show();
}
}
<receiver
android:name=".BlockOutgoing"
android:label="#string/app_name" >
<intent-filter android:priority="1">
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>

BroadCast Receiver calling intent not working for second time

In my i have a receiver to predict incoming calls,Once i have the call i need bring my app to front of screen(Over call accept and reject scree), the code for receiver is shown below,
public class IncomingCallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
Log.i("IncomingCallReceiver",bundle.toString());
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
Log.i("IncomingCallReceiver","State: "+ state);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
{
String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.i("IncomingCallReceiver","Incomng Number: " + phonenumber);
String info = "Detect Calls sample application\nIncoming number: " + phonenumber;
Intent intent2open = new Intent(context, com.varma.samples.detectcalls.ui.MainActivity.class);
intent2open.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent2open.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
String name = "KEY";
String value = "String you want to pass";
intent2open.putExtra(name, value);
context.startActivity(intent2open);
Toast.makeText(context, info, Toast.LENGTH_LONG).show();
}
}
}
in my manifest i added following parameters,
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name="com.varma.samples.detectcalls.ui.MainActivity"
android:label="#string/app_name" android:launchMode="singleTop" android:taskAffinity="#android:string/no">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="com.varma.samples.detectcalls.receivers.OutgoingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
</intent-filter>
</receiver>
<receiver android:name="com.varma.samples.detectcalls.receivers.IncomingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>
</application>
<uses-sdk android:minSdkVersion="3" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
But when i launch the activity the receiver is started to listen incoming calls,then i close all instance of app in Settings, when call is coming for first time, my app is bring front over answer & reject screen.
Then i push back button to reject my call. Then when i make a call again the activity was not bring in front of my dialing screen. I don`t know where is the problem.
