I am currently working on call announcer for android
My code works perfect on some devices but it do not work on some devices
Following is my code
public void onReceive(Context context, Intent intent) {
String state=intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
String number=intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast.makeText(context, "Incoming Number:"+number, Toast.LENGTH_SHORT).show();
}
}
the number is toasted on some devices but not all devices

I want to start a service after reboot. The problem I have is that this does not happen every time (at least the first 20 minnutes). I have study many questions into stackoverflow and try a number of the provided solutions however sometimes the service does not automaticaly start after reboot.
Also I have to add another parameter this of the foreground service for android versions O and above.
Could someone give me any advice?

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
ContextCompat.startForegroundService(context,serviceIntent);
} else {
context.startService(serviceIntent);
}
}
}
I also found in a comment here that reciever should be registered into an activity of the application and this is the code in Mainactivity. Do you agree?
#Override
protected void onCreate(Bundle savedInstanceState) {
...
final ComponentName onBootReceiver = new ComponentName(getApplication().getPackageName(), BootCompletedIntentReceiver.class.getName());
if(getPackageManager().getComponentEnabledSetting(onBootReceiver) != PackageManager.COMPONENT_ENABLED_STATE_ENABLED)
getPackageManager().setComponentEnabledSetting(onBootReceiver,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);
..
}
i have code in file manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

and in broadcastReceiver:
package com.ninhph.btvncallblock.receiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class CallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("call", "call coming: ");
}
}
But when i run and call in emulator, nothing happen, why? and how can i detect incoming call?
add <uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS"/> permission in AndroidManifest.xml also try set priority to intent filter like below code
<?xml version="1.0" encoding="utf-8"?>

String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast.makeText(context, "Hey! Calling Number : " + incomingNumber, Toast.LENGTH_LONG).show();
}
}
}
I'm wondering why this simple receiver for detecting connection change don't work for me, it is like with al other sample which i search on google
in this sample application i have only one activity and broadcast
BroadcastReceiver:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class ConnectivityReceiver extends BroadcastReceiver {
public ConnectivityReceiver() {
super();
}
#Override
public void onReceive(Context context, Intent arg1) {
Log.e("onReceive ", " , ");
}
}
manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sample.sampleapp">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<receiver
android:name=".ConnectivityReceiver"
android:enabled="true">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
</intent-filter>
</receiver>
</application>
</manifest>
after turning on/off i dont have any output on logcat
and its my activity:
public class MainActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
If your application is targeting Android N, then you must have to register your CONNECTIVITY_CHANGE broadcast dynamically Context.registerReceiver().

Android N Background Optimizations
I want my application to launch browser when boot my tablet but its crashing on boot time. If someone please let me know my mistake? I write nothing in my activity_main.xmle. Its showing me message "unfortunately the application crashed".

separate both classes and fix mainfest like below

write MainActiity
MainActivity {
...}
BootReceiver class
package com.example.BootReciever;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootReciever extends BroadcastReceiver {
#Override
public void onReceive(Context ctx, Intent arg1) {
Intent iMainActivity = new Intent(ctx, yourMainActivityClass);
iMainStartActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(iMainActivity);
}
}
At a guess, I'd say it's probably because your manifest specifies .BootReceiver as the receiver, but based on your code the BootReceiver class is nested inside MainActivity. So you either need to move BootReceiver to a top-level class, or change your manifest to specify .MainActivity.BootReceiver as the receiver.
If that doesn't resolve it, please post your logcat so we can see what error is causing the crash.
Use this in the Manifest as receiver section:
<receiver
android:name=".BootReciever"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
And take care of Broadcast Receiver class that should be not inner:
package com.example.BootReciever;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootReciever extends BroadcastReceiver {
#Override
public void onReceive(Context ctx, Intent arg1) {
Intent iMainActivity = new Intent(ctx, MainActivity.class);
iMainStartActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(iMainActivity);
}
}
Your app starts so quick and doesn't let other important apps to start first I think you should add some delay in your app to start up. like this:
public class BootUpReceiver extends BroadcastReceiver {
#Override
public void onReceive(final Context context, Intent intent) {
// We can't wait on the main thread as it would be blocked if we wait for too long
new Thread(new Runnable() {
#Override
public void run() {
try {
// Lets wait some time before starting the service to be fair to other processes on startup
Thread.sleep(5000);
} catch (InterruptedException e) {
}
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
}).start();
}
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;
import android.widget.Toast;
public class BootupReceiver extends BroadcastReceiver {
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));
}
}
MainActivity.java
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.content.BroadcastReceiver;
import android.widget.Toast;
import android.content.Intent;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

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>
