After researching a lot, I found it out that there is not any way to achieve this funtionality without using reflection.
First you need to put headset jack in and then call the method setWiredDeviceConnectionState() with suitable parameters then it behave like the headphone are disconnected but click works still.
So it is a hack but as per my requirement, it's not a foolproof solution but working for now.
Here is my code to do this,
private void sendIntent(Intent i) {
Method m;
Log.i(TAG, "Device sdk = " + Build.VERSION.SDK_INT);
try {
if (Build.VERSION.SDK_INT < 16) {
Class<?> clazz = Class.forName("android.app.ActivityManagerNative");
m = clazz.getMethod("broadcastStickyIntent", Intent.class, String.class);
m.setAccessible(true);
m.invoke(clazz, i, null);
return;
} else if (Build.VERSION.SDK_INT < 23) {
//int type, int state, String address, String name
m = am.getClass().getMethod("setWiredDeviceConnectionState", Integer.TYPE, Integer.TYPE, String.class);
m.setAccessible(true);
Object[] objArr = new Object[3];
objArr[0] = (i.getIntExtra("microphone", 0) == 0) ? 8 : 4;
objArr[1] = i.getIntExtra("state", 0);
objArr[2] = i.getStringExtra("name");
m.invoke(am, objArr);
} else {
//int type, int state, String address, String name
m = am.getClass().getMethod("setWiredDeviceConnectionState", Integer.TYPE, Integer.TYPE, String.class, String.class);
m.setAccessible(true);
Object[] objArr = new Object[4];
objArr[0] = (i.getIntExtra("microphone", 0) == 0) ? 8 : 4;
objArr[1] = i.getIntExtra("state", 0);
objArr[2] = i.getStringExtra("address");
objArr[3] = i.getStringExtra("name");
m.invoke(am, objArr);
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
the intent to send :
@TargetApi(Build.VERSION_CODES.M)
public class HeadSetJackReciever extends AudioDeviceCallback {
public static boolean isAudioChecked;
public void onAudioDevicesAdded(AudioDeviceInfo[] addedDevices) {
if (addedDevices.length != 0) {
for (int i = 0; i < addedDevices.length; i++) {
if (addedDevices[i].getType() == AudioDeviceInfo.TYPE_WIRED_HEADSET) {
AudioDeviceInfo audioDeviceInfo = addedDevices[i];
int microphone = audioDeviceInfo.getType();
String headsetName = "DCS";
String headsetAddress = "";
try {
Method method = audioDeviceInfo.getClass().getMethod("getAddress");
method.setAccessible(true);
headsetAddress = (String) method.invoke(audioDeviceInfo);
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
Log.e("TEST", "microphone:"+microphone);
Log.e("TEST", "headsetName:"+headsetName);
Log.e("TEST", "headsetAddress:"+headsetAddress );
Intent intent = new Intent(ForegroundService.context, SelectAudioOutput.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("microphone",microphone);
intent.putExtra("headsetName",headsetName);
intent.putExtra("headsetAddress",headsetAddress);
ForegroundService.context.startActivity(intent);
}
}
}
}
public void onAudioDevicesRemoved(AudioDeviceInfo[] removedDevices) {
if (removedDevices.length != 0) {
Log.e("TEST", "Audio deinserted");
if (SplashScreen.preferences.getBoolean("isKey", false)) {
Intent startIntent = new Intent(ForegroundService.context, ForegroundService.class);
startIntent.setAction(Constants.ACTION.STARTNOTIFICATION_ACTION);
ForegroundService.context.startService(startIntent);
} else {
Intent startIntent = new Intent(ForegroundService.context, ForegroundService.class);
startIntent.setAction(Constants.ACTION.STOPNOTIFICATION_ACTION);
ForegroundService.context.startService(startIntent);
}
ForegroundService.audioManager.setMode(AudioManager.MODE_IN_CALL);
ForegroundService.audioManager.setSpeakerphoneOn(false);
}
}
}
for Lollipop and lower versions :
if (intent.getAction().equals(Intent.ACTION_HEADSET_PLUG)) {
headsetName = intent.getStringExtra("name");
microphone = intent.getIntExtra("microphone", 0);
int state = intent.getIntExtra("state", -1);
switch (state) {
case 0:
Log.d("onReceive", "Headset unplugged");
Log.e("TEST", "Audio deinserted");
if (SplashScreen.preferences.getBoolean("isKey", false)) {
Intent startIntent = new Intent(ForegroundService.context, ForegroundService.class);
startIntent.setAction(Constants.ACTION.STARTNOTIFICATION_ACTION);
context.startService(startIntent);
} else {
Intent startIntent = new Intent(ForegroundService.context, ForegroundService.class);
startIntent.setAction(Constants.ACTION.STOPNOTIFICATION_ACTION);
context.startService(startIntent);
}
ForegroundService.audioManager.setMode(AudioManager.MODE_IN_CALL);
ForegroundService.audioManager.setSpeakerphoneOn(false);
break;
case 1:
Log.d("onReceive", "Headset plugged");
Log.e("TEST", "microphone:"+microphone);
Log.e("TEST", "headsetName:"+headsetName);
Log.e("TEST", "headsetAddress:"+headsetAddress );
Intent intentone = new Intent(ForegroundService.context, SelectAudioOutput.class);
intentone.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intentone.putExtra("microphone",microphone);
intentone.putExtra("headsetName",headsetName);
intentone.putExtra("headsetAddress",headsetAddress);
context.startActivity(intentone);
break;
}
}
Let me know if I miss something.
Thanks.
