I'm trying to develop android app for that can record phone calls. So, in the initial step, I've to see if BroadcastReceiver is getting fired or not.
I've added permissions, receiver tag in AndroidManifest file. I'm testing on OnePlus X. Activity is gets started but BroadcastReceiver doesn't get fired when I get call. What's going wrong here?
<?xml version="1.0" encoding="utf-8"?>

package com.example.myapp;

public class PhoneStateReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
try {
System.out.println("Receiver start");
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
Toast.makeText(context,"Incoming Call State",Toast.LENGTH_SHORT).show();
Toast.makeText(context,"Ringing State Number is -"+incomingNumber,Toast.LENGTH_SHORT).show();
}
if ((state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))){
Toast.makeText(context,"Call Received State",Toast.LENGTH_SHORT).show();
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
Toast.makeText(context,"Call Idle State",Toast.LENGTH_SHORT).show();
}
}
catch (Exception e){
e.printStackTrace();
}
}
}
The permission READ_PHONE_STATE is a dangerous permission, if you are on a marshmallow device you must request runtime permission else your broadcast receiver will not work neither it will throw an error.
That is the most likely the cause of issue from your code because you have correctly registered in the Intent filter other than that there is nothing wrong as it is just a broadcast receiver and should work, i.e get called by the Android system.

I've created a custom deep link dispatcher in Java within a react native project.
The issue I'm having is that I can't get MainActivity to start from my dispatcher, and I can't quite figure out why.
I have AndroidManifest set up so that the deep link is captured in LinkDispatcherActivity effectively, but the startActivity(dispatchedIntent) never reaches MainActivity, which is where I assume it needs to go. Ordinarily in AndroidManifest.xml, deep links would be sent to MainActivity).
It does open the app, but I assume it's because LinkDispatcherActivity is part of the app? Not sure, if I say something dumb it's because this is only my 3rd day in a row writing Java 😰
Below is my code.
package com.example.app;
//Inspired by https://github.com/justeat/Android.Samples.Deeplinks, Licensed under Apache 2.0
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import net.openid.appauth.RedirectUriReceiverActivity;
public class LinkDispatcherActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
dispatchIntent(getIntent());
} catch (IllegalArgumentException iae) {
// Malformed URL
if (BuildConfig.DEBUG) {
Log.e("Deep links", "Invalid URI", iae);
}
} finally {
// Always finish the activity so that it doesn't stay in our history
finish();
}
}
public void dispatchIntent(Intent intent) {
final Uri uri = intent.getData();
final String host = uri.getHost().toLowerCase();
if (uri == null) throw new IllegalArgumentException("Uri cannot be null");
// Default intent
Intent dispatchedIntent = new Intent(LinkDispatcherActivity.this, MainActivity.class);
dispatchedIntent.setData(uri);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
Log.d(dispatchedIntent.getDataString(), "dispatchIntent: intent string");
// Auth intent only, this is why I need the dispatcher
if ("login".equals(host)) {
dispatchedIntent = new Intent(this, RedirectUriReceiverActivity.class);
dispatchedIntent.putExtra("requestCode", 0);
Log.d("Login", "mapAppLink: ");
startActivityForResult(dispatchedIntent, 0);
return;
}
Log.d("Default", "mapAppLink: ");
startActivity(dispatchedIntent);
}
}

Edit: for the intent, I've tried:
new Intent(getApplicationContext(), MainActivity.class)
new Intent(reactContext, MainActivity.class) (extending ReactActivity instead of Activity)
new Intent(this, MainActivity.class)
new Intent("MainActivity")
Try adding RedirectUriReceiverActivity to the manifest - I couldn't see it in there.
<activity android:name="com.facebook.react.devsupport.RedirectUriReceiverActivity" />
This is what I ended up with for the LinkDispatcherActivity. To summarize, what I did was dispatch the intents that the deep activities were eventually supposed to invoke directly, instead of trying to forward the intent. In other words, if you're trying to pass an intent from one activity to another, maybe don't and consider dispatching the activity/function/intent that you want to run afterwards. I still think forwarding the intent should have worked, but this is what ended up working.
In order to accomplish the above, I:
Called a function within the AppAuth package that generates an intent, and dispatch it
Used ReactContext to emit the url listener event that React Native uses to respond to deep links.

I have a service that I want to use for remotely managing my device. When it starts up it's supposed to connect to a server and then receive commands from there. When I start my App normally I have the MainActivity fire up my service using
startService(new Intent(this, service.class));
This works perfectly fine. However, when the autostart.class fire up the service it's reporting that it can't resolve the host. So I simply had it retry every second until it is connected but it is never able to connect even though the network connection is up and working perfectly. When I click on the App icon then, it kills the old service, starts a new one, connects and everything works great, but not with the automatic startup. It's like the service doesn't have any permissions when it's started up, but I'm not sure about that.
autostart.class
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class autostart extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent pushIntent = new Intent(context, service.class);
pushIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startService(pushIntent);
Log.i("Boot Receiver", "Service started");
}
}

In general I check the connectivity with this (although getAllNetworkInfo is deprecated)
public boolean areWeConnected(){
/**

* Always call this before attempting to perform data transactions.
*/
boolean haveConnectedWifi = false;
boolean haveConnectedMobile = false;
ConnectivityManager cm = (ConnectivityManager) getSystemService(getApplicationContext().CONNECTIVITY_SERVICE);
NetworkInfo[] netInfo = cm.getAllNetworkInfo();
for (NetworkInfo ni : netInfo) {
if (ni.getTypeName().equalsIgnoreCase("WIFI"))
if (ni.isConnected()){
haveConnectedWifi = true;
break;
}
if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
if (ni.isConnected()){
haveConnectedMobile = true;
break;
}
}
return haveConnectedWifi || haveConnectedMobile;
}
I'm trying to start my background service when the device boots, but nothing is happening. This is my code:

Log.e("it.Test", "***** SERVICE STARTED *****");
/*

*/
}
}
When my phone boots I don't see any toast (I don't see either the "My AppService Started" nor the "My AppService Stopped" toast) and nothing gets logged by the application...
Anyone knows what I am doing wrong??
Thanks!
EDIT: Solution to the problem
After seeing the post Trying to start a service on boot on Android linked in an answer and after many debugging I found the solution to my problem :) Thank to everyone!
Modification to AndroidManifest.xml
Added inside <application>:
<receiver android:name="it.test.Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service
android:name="it.test.AppService"
android:enabled="true" />
Added also:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
[...]
android:installLocation="internalOnly">
Modifications to AppService.java
To make the service work, I had to override in the AppService class onStartCommand instead of onStart, so I completely removed the method onStart from my class.
New onStartCommand:
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "My AppService Started", Toast.LENGTH_LONG).show();
Log.e("it.Test", "***** SERVICE STARTED ***** from onStartCommand");
MainActivity.calc(this);
MainActivity.save();
return Service.START_REDELIVER_INTENT;//todo I'm not sure about what I have to return
}
Your broadcast receiver is not registered at AndroidManifest.xml
You need to register the broadcast receiver:
<receiver android:name=".<RECEIVER_NAME>">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
If your app is installed to external storage it won't receive BOOT_COMPLETE broadcast message. To prevent this you can install your application in internal storage. you can do this just adding this line in AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:installLocation="internalOnly"
... >
Source: https://stackoverflow.com/a/32938071/1549700
You have you register your broadcast receiver and service under the <application> tag
<!-- [START service_listener] -->
<service
android:name=".it.test.AppService"
android:enabled="true" />
<!-- [END service_listener] -->
<!-- [START broadcast_receiver] -->
<receiver android:name=".it.test.Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<!-- [END broadcast_receiver] -->
You need to register the broadcast receiver:
<receiver android:name=".Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
You need this in your manifest file:
<receiver android:name=".it.test.Autostart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
Have you register broadcast receiver in manifest file and also also give boot completed permission in your broadcast receiver, if any problem then ask in comment, your code is perfect.
I have tried this on a few android phones with no luck (i did start the app once).
This was mostly generated from android studio 1.3.2 and from some questions like this and that and the other.
Perhaps someone can point out what i am doing wrong.
Thanks
edit: moved receiver inside app, but no joy.
edit2: added missing permissions for receiver. now seems to work on a nexus 4. but not on the kindle fire or the at&t tablets. although it seems to come right away if i press the circle icon on the azpen.
edit3: seems to work sometimes on the fires now.

Every Component must be declared inside application tag into manifest. Here you declared receiver outside of application tag. Read Structure of the Manifest File.
Correct manifest wil be
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="acme.startup" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<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>
<receiver
android:name=".BootReceiver"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
You have to add permission to manifest file. Add this before your <application> tag :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
I want to block incoming SMS message as long as my application is running . I could achieve that but the problem is after I close the app or even restart or even uninstall it the user will not be able to receive SMS message anymore . So How can I make the application to block incoming SMS only when it's running and when it gets closed or uninstalled etc.. to stop blocking SMS. Here's my code :
BroadCastReceiver.Java
package com.example.sms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
public class BroadCastReceiver extends BroadcastReceiver
{
public void onReceive(Context context, Intent intent)
{
abortBroadcast();
}
}
MainActivity.java
package com.example.sms;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Manifiest :
<?xml version="1.0" encoding="utf-8"?>

Check if your app is running then only abort broadcast receiver else not
//define this variable above onReceive() with default value as false;
boolean appRunningInBack=false;
ActivityManager am = (ActivityManager) mContext.getSystemService(Activity.ACTIVITY_SERVICE);
String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();
if(packageName.equalIgnoreCase("your app package name") || appRunningInBack)
{
