Learning broadcast messages. The book DN Kolisnichenko - "Programming for Android" is an example of where the camera at the touch of a button starts the service. But I have it che does not work. What is the problem? Or I do not know what is the camera button (physical or on the display), or do not understand what is wrong. Here is the code of the example:
MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.content.Intent;
import android.content.IntentFilter;
public class MainActivity extends AppCompatActivity {
MyReceiver iReceiver = new MyReceiver();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter iFilter = new IntentFilter(Intent.ACTION_CAMERA_BUTTON);
iFilter.addAction(Intent.ACTION_CAMERA_BUTTON);
registerReceiver(iReceiver, iFilter);
}
#Override
protected void onDestroy() {
unregisterReceiver(iReceiver);
super.onDestroy();
}
}
MyReceiver.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context rcvContext, Intent rcvIntent) {
String action = rcvIntent.getAction();
if (action.equals(Intent.ACTION_CAMERA_BUTTON)) {
rcvContext.startService(new Intent(rcvContext,
MyService.class));
}
}
}
MyService.java
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class MyService extends Service {
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
Toast.makeText(this,"Service started...",
Toast.LENGTH_LONG).show();
}
#Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service destroyed...",
Toast.LENGTH_LONG).show();
}
}

I've tried:
This which doesn't work on my phone:
Trying to start a service on boot on Android
This which also fails to work properly:
http://www.compiletimeerror.com/2014/12/android-autostart-app-after-boot-with.html#.VpL6sxWLTIU
And a few others which I couldn't find again. Could someone please post a working example of code which will start a MainActivity with the default HelloWorld xml layout?
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"

</manifest>
package com.example;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, MyService.class);
context.startService(startServiceIntent);
}
}
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MyService extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_service);
}
}
First：create a BroadcastReceiver, onReceive(Context context, Intent intent)，start the app you want to startup in this method
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
xxx.class is the app you want to start
Intent service = new Intent(context,XXXclass);
context.startService(service);
Log.v("TAG", "you want to startup this app.....");
Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
context.startActivity(intent );
} }
Secondly:configure receiver and intent-filter
<receiver android:name="BootBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
THirdly,add permission
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
I have an application in android and phonegap and I'm using Parse to send pushs.
Everything works fine when I install it: I can send and receive notifications.
After 5 hours, it starts to delay the pushs and after one day, it stops and I cant receive it anymore.
I see the notifications in dashboard but not in device.
Can someone give me a sugestion ?

Just to let you know I solved it.
In my Manifest,inside <application>, I'm using the GCM Parse support and my notifications are working now:
<receiver android:name="com.parse.GcmBroadcastReceiver"

<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />

<category android:name="com.example.meeto1" />
</intent-filter>
I am testing the following app on HTC with Android 2.3.5. For some reason app is not launching on restarting or booting the phone.
I need to know where am I wrong exactly?
BootReciever.java
import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;

public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "App started", Toast.LENGTH_LONG).show();
/*
Intent startActivityIntent = new Intent(context, MainActivity.class);
startActivityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startActivityIntent);
*/
// context.startActivity(new Intent(context, MainActivity.class));
}
}

import android.content.Intent;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Android Manifest File:

The code is working on restart but not on turning on the phone after shutting it down. Here are the messages that I receive in my logcat:
You extended BootupReceiver with Activity?
It should be extended with Broadcast Receiver.
public class BootupReceiver extends BroadcastReceiver{
}
Your Receiver:
public class AutoStartBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent receivedIntent) {
context.startActivity(new Intent(context, YourActivity.class));
}
}
Your Manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name="com.example.receiver.AutoStartBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Good luck!
You need to write following permission,
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
If your application is stored on External storage then you should provide following intent filter,
<receiver android:name=".BootupReceiver">
<intent-filter>
<action android:name="android.intent.action.ACTION_EXTERNAL_APPLICATIONS_AVAILABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
See App Install Location.
I am trying to test Broadcast receiver for outgoing calls. Please help.
Here is my CallCounter class:
package com.callout;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class CallCounter extends PhoneStateListener {
public void onCallStateChanged(int state, String incomingNumber) {
switch(state) {
case TelephonyManager.CALL_STATE_IDLE:
Log.d("Tony+++++++++++","Outgoing Call finished");
// Call Finished -> stop counter and store it.
// callStop=new Date().getTime();
Context c = getApplicationContext();
c.stopService(new Intent(c,ListenerContainer.class));
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("++++++++++++++++Tony","Outgoing Call Starting");
// Call Started -> start counter.
// This is not precise, because it starts when calling,
// we can correct it later reading from call log
// callStart=new Date().getTime();
break;
}
}
private Context getApplicationContext() {
// TODO Auto-generated method stub
return this.getApplicationContext();
}
}
Here is myReceiver
package com.callout;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class myReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
Log.d("T+++++++++++++++++ony","In mYRecieverrr");
context.startService(new Intent(context,ListenerContainer.class));
}
}
}
Here is myService:
package com.callout;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class ListenerContainer extends Service {
public class LocalBinder extends Binder {
ListenerContainer getService() {
Log.d("Tony","OKKK HEREEEEEEEEEEEEEeEEEEE");
return ListenerContainer.this;
}
}
#Override
public void onStart(Intent intent, int startId) {
TelephonyManager tManager =(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
CallCounter callCounter=new CallCounter();
tManager.listen(callCounter,PhoneStateListener.LISTEN_CALL_STATE);
Log.d("To++++++++++++++ny","Call COUNTER Registered");
}
#Override
public IBinder onBind(Intent intent) {
return mBinder;
}
private final IBinder mBinder = new LocalBinder();
}
And this is the manifest file if i m missing some permission:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.callout"
android:versionCode="1"
android:versionName="1.0">

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".CallCounter"
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=".myReceiver"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:enabled="true" android:name=".ListenerContainer" />
<receiver android:name=".myReceiver">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
</application>
</manifest>
Please point out my mistake.
You must add the following permission to your manifest since your are registering a phonestatelistener.
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
It looks like your receiver is missing an attribute in the manifest file :
http://developer.android.com/guide/topics/manifest/receiver-element.html
Look at the exported attribute, it should be set tot true to receive broadcast from other apps.

Program doesn't enter into the onReceive Mathod of MyBroadCastReceiver class.
First, i suggest you to format your code here. So that people here will be glad to read your problem code.
Your code list above does NOT register any BroadcastReceiver to the system. You'd better to check out ApiDemo for more details.
