I m developing an android app in which I want to display a toast during incoming call my app is running fine when screen is unlocked. But its not displaying anything when home screen is locked, can anyone help me.
Here is my whole code
package com.example.lenovo.call_toast;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.PowerManager;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity_service extends Activity {
private boolean detectEnabled;
private TextView textViewDetectState;
private Button buttonToggleDetect;
private Button buttonExit;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PowerManager mgr = (PowerManager)getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
wakeLock.acquire();
textViewDetectState = (TextView) findViewById(R.id.textViewDetectState);
buttonToggleDetect = (Button) findViewById(R.id.buttonDetectToggle);
buttonToggleDetect.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
setDetectEnabled(!detectEnabled);
}
});
buttonExit = (Button) findViewById(R.id.buttonExit);
buttonExit.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
setDetectEnabled(false);
MainActivity_service.this.finish();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
private void setDetectEnabled(boolean enable) {
detectEnabled = enable;
Intent intent = new Intent(this, CallDetectService.class);
if (enable) {
// start detect service
startService(intent);
buttonToggleDetect.setText("Turn off");
textViewDetectState.setText("Detecting");
}
else {
// stop detect service
stopService(intent);
buttonToggleDetect.setText("Turn on");
textViewDetectState.setText("Not detecting");
}
}
}
This is my service to detect call
package com.example.lenovo.call_toast;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
public class CallDetectService extends Service {
private CallHelper callHelper;
public CallDetectService() {
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
callHelper = new CallHelper(this);
int res = super.onStartCommand(intent, flags, startId);
callHelper.start();
return res;
}
@Override
public void onDestroy() {
super.onDestroy();
callHelper.stop();
}
@Override
public IBinder onBind(Intent intent) {
// not supporting binding
return null;
}
}
And this is another class
package com.example.lenovo.call_toast;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
public class CallHelper {
/**
* Listener to detect incoming calls.
*/
private class CallStateListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
// called when someone is ringing to this phone
Toast.makeText(ctx,
"Incoming: " +incomingNumber,
Toast.LENGTH_LONG).show();
break;
}
}
}
/**
* Broadcast receiver to detect the outgoing calls.
*/
public class OutgoingReceiver extends BroadcastReceiver {
public OutgoingReceiver() {
}
@Override
public void onReceive(Context context, Intent intent) {
String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.e( "onCallStateChanged: ",number );
Toast.makeText(ctx,"Outgoing: "+number,
Toast.LENGTH_LONG).show();
}
}
private Context ctx;
private TelephonyManager tm;
private CallStateListener callStateListener;
private OutgoingReceiver outgoingReceiver;
public CallHelper(Context ctx) {
this.ctx = ctx;
callStateListener = new CallStateListener();
outgoingReceiver = new OutgoingReceiver();
}
/**
* Start calls detection.
*/
public void start() {
tm = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
tm.listen(callStateListener, PhoneStateListener.LISTEN_CALL_STATE);
IntentFilter intentFilter = new IntentFilter(Intent.ACTION_NEW_OUTGOING_CALL);
ctx.registerReceiver(outgoingReceiver, intentFilter);
}
/**
* Stop calls detection.
*/
public void stop() {
tm.listen(callStateListener, PhoneStateListener.LISTEN_NONE);
ctx.unregisterReceiver(outgoingReceiver);
}
}
And here is the manifest file
