I am trying to make a custom layout for incoming and outgoing calls, and while the call is in the progress a specific image will be shown which has to stay visible even when user covers proximity sensor. I tried with wakelock but no success, now I am using proximity sensor which will just hide buttons and leave image to be displayed. This is working on some phones and all of the emulators but there are few samsung and sony phones that simply turn off the screen when close to sensor. This is my code for proximity sensor:
#Override
protected void onPause() {
super.onPause();
}
#Override
protected void onResume() {
super.onResume();
Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
sensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_NORMAL);
}
#Override
public void onSensorChanged(SensorEvent event) {
float distance = event.values[0];
if(distance < 4){
buttonsLayout.setVisibility(View.INVISIBLE);
}
else {
buttonsLayout.setVisibility(View.VISIBLE);
}
}
Any help is appreciated.
Edit:
I am making calls with these:
android.telephony.PhoneStateListener
android.telephony.TelephonyManager
com.android.internal.telephony.ITelephony (using reflection)
This is how I accept calls:
private void acceptCall() {
timerLayout.setVisibility(View.VISIBLE);
answerButton.setVisibility(View.GONE);
startTime = SystemClock.uptimeMillis();
customHandler.postDelayed(updateTimerThread, 0);
try {
Runtime.getRuntime().exec("input keyevent " +
Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK));
} catch (IOException e) {
String enforcedPerm = "android.permission.CALL_PRIVILEGED";
Intent btnDown = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
Intent btnUp = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
sendOrderedBroadcast(btnDown, enforcedPerm);
sendOrderedBroadcast(btnUp, enforcedPerm);
}
}
My requirement is Accept and Disconnect a incoming call.
It is working fine If Call is Accepted and then wait for 3 seconds(handler.postDelayed) and then Disconnecting.
But I wanna disconnect the call immediately after accepting.(Dont wanna wait for 3 sconds)
Here is my code. Your help is appreciated.
public void acceptAndDissConnectCall(final Context activity) {
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (currentapiVersion >= android.os.Build.VERSION_CODES.LOLLIPOP){
Log.i(TAG, "It is LOLLIPOP or Greater====");
answerCall(activity);
} else{
// do something for phones running an SDK before lollipop
Log.i(TAG, "This device is prior to LOLLIPOP ====");
acceptCall(activity);
}
dissConnectCall(activity);
}
public boolean dissConnectCall(final Context activity) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
try {
Log.d(TAG, "Dissconnect call ===== ");
// Get the boring old TelephonyManager
TelephonyManager telephonyManager = (TelephonyManager) activity.getSystemService(Context.TELEPHONY_SERVICE);

Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("endCall");
// Invoke endCall()
methodEndCall.invoke(telephonyInterface);
} catch (Exception ex) { // Many things can go wrong with reflection calls

}
}, 4000);
return false;
}
public static void acceptCall(Context context){
Log.d(TAG, "accept the call ====");
Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);

}
}
}).start();
}
In your dissConnectCall method change value 4000 in run method to lowest.
handler.postDelayed(new Runnable() {
#Override
public void run() {
.......
}
}, 4000);//decrease this value to 100
I'm trying to put an activity in the background or simply kill it. I'm creating the activity inside a runnable, because I need to wait 2 seconds before it opens:
case TelephonyManager.CALL_STATE_RINGING:
long user_logged = AppSettings.getLoggedUserSQLiteID(context);
if (user_logged != 0) {
final Handler h = new Handler();
Runnable r1 = new Runnable() {
#Override
public void run() {
String phoneNr = inte.getStringExtra("incoming_number");
Intent phonecall = new Intent(ctx, PhoneCall.class);
phonecall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
phonecall.putExtra("phone_number", phoneNr);
ctx.startActivity(phonecall);
}
};
h.postDelayed(r1, 2000); // 1 second delay
}
break;
In the button I specify the method to run on click, like android:onClick="acceptCall":
public void acceptCall(View v) {
try {
Runtime.getRuntime().exec("input keyevent " + Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK));
} catch (IOException e) {
// Runtime.exec(String) had an I/O problem, try to fall back
String enforcedPerm = "android.permission.CALL_PRIVILEGED";
Intent btnDown = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_HEADSETHOOK));
Intent btnUp = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK));
this.sendOrderedBroadcast(btnDown, enforcedPerm);
this.sendOrderedBroadcast(btnUp, enforcedPerm);
super.finish();
}
}
To finish, or put it in the background, I tried these lines of code:
super.finish();
super.moveTaskToBack(true);
this.finish();
this.moveTaskToBack(true);
However, none of them seems to work for me. Can anyone help me understand why?
In default case to kill activity, we should use:
MyActivity is your activity.
MyActivity.this.finish();
//try to kill your activity after this line of your code:
ctx.startActivity(phonecall);
Is it possible to control playback of the Spotify app from within another Android app? I'm only looking for track skipping functionality (forward and backward).
I'm aware of the Spotify Android SDK, but it seems to only allow skipping of tracks played by the SDK:
com.spotify.sdk.android.playback.NativeSpotifyException: Failed SpPlaybackSkipToPrev with error code 14 (The operation is not supported if the device is not the active playback device)
To clarify, both the actual Spotify app, and my own app are running on the same device
Here's how to do it:
This will try to play/pause Spotify. If it's not running it will start it and make it start playing.
public void nextSong() {
int keyCode = KeyEvent.KEYCODE_MEDIA_NEXT;
if (!isSpotifyRunning()) {
startMusicPlayer();
}
Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
intent.setPackage("com.spotify.music");
synchronized (this) {
intent.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, keyCode));
getContext().sendOrderedBroadcast(intent, null);
intent.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, keyCode));
getContext().sendOrderedBroadcast(intent, null);
}
}
public void playPauseMusic() {
int keyCode = KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE;
if (!mAudioManager.isMusicActive() && !isSpotifyRunning()) {
startMusicPlayer();
}
Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
i.setPackage("com.spotify.music");
synchronized (this) {
i.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, keyCode));
getContext().sendOrderedBroadcast(i, null);
i.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, keyCode));
getContext().sendOrderedBroadcast(i, null);
}
}
private void startMusicPlayer() {
Intent startPlayer = new Intent(Intent.ACTION_MAIN);
startPlayer.setPackage("com.spotify.music");
startPlayer.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getContext().startActivity(startPlayer);
if (mMusicPlayerStartTimer != null) {
mMusicPlayerStartTimer.cancel();
}
mMusicPlayerStartTimer = new Timer("MusicPlayerStartTimer", true);
mMusicPlayerStartTimer.schedule(new MusicPlayerStartTimerTask(), DateUtils.SECOND_IN_MILLIS, DateUtils.SECOND_IN_MILLIS);
}
private boolean isSpotifyRunning() {
Process ps = null;
try {
String[] cmd = {
"sh",
"-c",
"ps | grep com.spotify.music"
};
ps = Runtime.getRuntime().exec(cmd);
ps.waitFor();
return ps.exitValue() == 0;
} catch (IOException e) {
Log.e(DEBUG_TAG, "Could not execute ps", e);
} catch (InterruptedException e) {
Log.e(DEBUG_TAG, "Could not execute ps", e);
} finally {
if (ps != null) {
ps.destroy();
}
}
return false;
}
private class MusicPlayerStartTimerTask extends TimerTask {
#Override
public void run() {
if (isSpotifyRunning()) {
playPauseMusic(null);
cancel();
}
}
}
EDIT: Added full example code
Yes, you can control playback using the RemoteController classes, or if using Lollipop, the MediaController classes, or if supporting L and earlier, then the MediaControllerCompat classes.
Then perform dispatchMediaButtonEvent() with KEYCODE_MEDIA_NEXT.
Quick answer - No, this isn't possible.
I am writing an android app in which I need to answer an incoming call, do some work and then end the call.
After all the Googling I could find two different ways to achieve this both of which do not work with recent versions of Android, specifically after 4.1, Jelly Bean.
I.) Access "com.android.internal.telephony.ITelephony" using Java Reflection in the Broadcast receiver for "android.intent.action.PHONE_STATE". Below sample code can be found in hundreds of related post:
public class PhoneCallReceiver extends BroadcastReceiver {
Context context = null;
private static final String TAG = "Phone call";
private ITelephony telephonyService;
#Override
public void onReceive(Context context, Intent intent) {
if (!intent.getAction().equals("android.intent.action.PHONE_STATE"))
return;
Log.v(TAG, "Receving....");
TelephonyManager telephony = (TelephonyManager)
context.getSystemService(Context.TELEPHONY_SERVICE);
try {
Log.v(TAG, "Get getTeleService...");
Class c = Class.forName(telephony.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
telephonyService = (ITelephony) m.invoke(telephony);
telephonyService.silenceRinger();
Log.v(TAG, "Answering Call now...");
telephonyService.answerRingingCall();
Log.v(TAG, "Call answered...");
//telephonyService.endCall();
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG,
"FATAL ERROR: could not connect to telephony subsystem");
Log.e(TAG, "Exception object: " + e);
}
}
}
The problem with this code is that
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
is required for this method to work, and this permission has been defined as "for system apps only" from android v 2.3. In short, normal user apps can not define this permission in the manifest file anymore.
II.) Another way is to simulate pushing of the Headset hook which makes Android answer the call. This is done by broadcasting the "Intent.ACTION_MEDIA_BUTTON" as shown in below code.
public class PhoneCallReceiver extends BroadcastReceiver {
Context context = null;
private static final String TAG = "Phone call";
#Override
public void onReceive(Context context, Intent intent) {
if (!intent.getAction().equals("android.intent.action.PHONE_STATE"))
return;
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Intent answer = new Intent(Intent.ACTION_MEDIA_BUTTON);
answer.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(answer, null);
Log.d(TAG, "Answered incoming call from: " + number);
}
return;
}
}
This method works till Android 4.1 after which android has restricted user apps from broadcasting "Intent.ACTION_MEDIA_BUTTON".
So my conclusion is that currently there is no way how we can achieve this in Android 4.1 or later.
Has anybody else found any other solution or workaround to this problem?
This works from Android 2.2 to 4.0 and now after adding the try catch to the last line it works for 4.1.2 and 4.2 Frankly speaking dont know how it works but it works for me.
Log.d(tag, "InSecond Method Ans Call");
// froyo and beyond trigger on buttonUp instead of buttonDown
Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");
Intent headSetUnPluggedintent = new Intent(Intent.ACTION_HEADSET_PLUG);
headSetUnPluggedintent.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY);
headSetUnPluggedintent.putExtra("state", 0);
headSetUnPluggedintent.putExtra("name", "Headset");
try {
sendOrderedBroadcast(headSetUnPluggedintent, null);
} catch (Exception e) {
e.printStackTrace();
}
This is working for me in Android 4.1.2 as well as i have tested on 4.2
This still gives an exception which is handled.
Edit for End Call
Hope this helps all the people looking for total solution for answer and end call.
/**
* Reject button click listener will reject the incoming call.

try {
// telephonyService.silenceRinger();
telephonyService.endCall();

Log.d(tag, "ignoreCall" + "Error: " + e.getMessage());
}
}
/**

}
My application has been using the following code to answer the phone for about 6 months:
Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
i.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(i, null);
I have tested this on Android Versions from 2.2 to 4.2.2. I have not seen a SecurityException broadcasting "Intent.ACTION_MEDIA_BUTTON" in my testing n a 4.2.2 device, nor have I seen crash reports from the Play Store indicating such exceptions are occurring.
I will say that this does not always work. It does not work on HTC devices due to the fact that HTC devices have a HeadsetObeserver that listen for the actually plugging in of a wired headset. Without this event, which it is currently a SecurityException for a third party app to broadcast, the HeadsetHook KeyEvent goes ignored.
The previous answers are misleading. The following code block does nothing:
Intent headSetUnPluggedintent = new Intent(Intent.ACTION_HEADSET_PLUG);
headSetUnPluggedintent.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY);
headSetUnPluggedintent.putExtra("state", 0);
headSetUnPluggedintent.putExtra("name", "Headset");
try {
sendOrderedBroadcast(headSetUnPluggedintent, null);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
except generate a SecurityException and catch it.
In the other answers where the code works, it is because of the KeyEvent.KEYCODE_HEADSETHOOK being broadcast.
Try this
Answer for end the call using pro grammatically. Its working fine for me.
try {
String serviceManagerName = "android.os.ServiceManager";
String serviceManagerNativeName = "android.os.ServiceManagerNative";
String telephonyName = "com.android.internal.telephony.ITelephony";
Class telephonyClass;
Class telephonyStubClass;
Class serviceManagerClass;
Class serviceManagerStubClass;
Class serviceManagerNativeClass;
Class serviceManagerNativeStubClass;
Method telephonyCall;
Method telephonyEndCall;
Method telephonyAnswerCall;
Method getDefault;
Method[] temps;
Constructor[] serviceManagerConstructor;
// Method getService;
Object telephonyObject;
Object serviceManagerObject;
telephonyClass = Class.forName(telephonyName);
telephonyStubClass = telephonyClass.getClasses()[0];
serviceManagerClass = Class.forName(serviceManagerName);
serviceManagerNativeClass = Class.forName(serviceManagerNativeName);
Method getService = // getDefaults[29];
serviceManagerClass.getMethod("getService", String.class);
Method tempInterfaceMethod = serviceManagerNativeClass.getMethod(
"asInterface", IBinder.class);
Binder tmpBinder = new Binder();
tmpBinder.attachInterface(null, "fake");
serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
telephonyObject = serviceMethod.invoke(null, retbinder);
//telephonyCall = telephonyClass.getMethod("call", String.class);
telephonyEndCall = telephonyClass.getMethod("endCall");
//telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");
telephonyEndCall.invoke(telephonyObject);
} catch (Exception e) {
e.printStackTrace();
Log.error(DialerActivity.this,
"FATAL ERROR: could not connect to telephony subsystem");
Log.error(DialerActivity.this, "Exception object: " + e);
}
As a conclusion to this thread, here is the code that works for me for Android 4.2.2.
--> Call is answered by simulating push of headset hook and keeping the broadcast in try-catch as mentioned by #PravinDodia in abouve thread. (Observe that an exception is thrown and handled in catch and the call is answered anyway. So I guess we can just ignore this exception and continue living life as if nothing happened! )
--> Call is disconnected using ITelephony.

At least the disconnect functionality works and we know how it works. So those who want to develop a Call Barring application can go ahead.
For those like me who want to answer a call, I guess we can use this for now and only hope that it does not stop working in the next version.
Try this :
Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");
// froyo and beyond trigger on buttonUp instead of buttonDown
Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");
Add permissions in AndroidManifest.xml file as
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
ITelephony method does not work on 4.4 and I find the headset/media button method still allows a fairly long ring before hangup.
This chaps blog post shows a new method that I have tested as working on 4.4.2 Galaxy s4 and HTC one mini that hangs up much more quickly and you don't get a missed call entry either.
http://aprogrammersday.blogspot.co.uk/2014/05/disconnect-block-drop-calls-android-4.html
The technique uses a runtime exec as below, apparently you may need to use a different number for some devices.
public class HangupPhoneCallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (TelephonyManager.EXTRA_STATE_RINGING.equals(intent.getStringExtra(TelephonyManager.EXTRA_STATE))) {
Executor eS = Executors.newSingleThreadExecutor();
eS.execute(new Runnable() {
#Override
public void run() {
Runtime runtime = Runtime.getRuntime();
try {
Log.d(TAG, "service call phone 5 \n");
runtime.exec("service call phone 5 \n");
} catch (Exception exc) {
Log.e(TAG, exc.getMessage());
}
}
});
return;
}
}
}
Call disconnecting using IT Telephony doesn't work on some devices like Samsung S Duos. But you can still make ringer silent :)
To end call in older version then 9.0
use this:
TelephonyManager tm = (TelephonyManager)context.getSystemService(TELEPHONY_SERVICE);
Method m1 = null;
try {
m1 = tm.getClass().getDeclaredMethod("getITelephony");
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
m1.setAccessible(true);
Object iTelephony = null;
try {
iTelephony = m1.invoke(tm);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
Method m3 = null;
try {
m3 = iTelephony.getClass().getDeclaredMethod("endCall");
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
try {
m3.invoke(iTelephony);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
