You are using a Manifest-declared receiver. This receiver would get invoked outside from other app or with some system events.
The receiver then becomes a separate entry point into your app which means that the system can start the app and deliver the broadcast if the app is not currently running.
If you want to trigger this receiver within the app you should register this receiver. In your case inside the MainActivity within onCreate or onResume as follows
broadcastReceiver = new MyReceiver ()
Intent filter = new IntentFilter("com.myapplication.BOOT")
registerReceiver(broadcastReceiver, filter)
Also you need to unregister it within onDestroy or onPause
unregisterReceiver(broadcastReceiver)
I guess you should use Context-registered receiver for your use case where you want to send a broadcast within the app. Its almost the same except that you don't need to define it inside the manifest.

im learning Android, and im triying to make and app that changes the image in the imageView when I rotate the phone, I´ve tried to get the broadcast receiver value, I would like some advice in how to do it, here's the code, sorry if its to much code, but i dont know where i am missing

I am trying to make broadcast receiver which will show a toast message when user click on button from my another app activity.
But receiver not showing result.
My code is below
My Receiver App
MyReceiver:
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 context, Intent intent) {
Toast.makeText(context, "Broadcast has been received!", Toast.LENGTH_LONG).show();
}
}
Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.xyz.receivebroadcast">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.example.xyz.broadcasts"></action>
</intent-filter>
</receiver>
</application>
My sender app
My MainActivity which sends the broadcasts is here.
MainActivity:
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void SendOutBroadcast(View view){
Intent i = new Intent();
i.setAction("com.example.xyz.broadcasts");
i.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
sendBroadcast(i);
}
}
activity_main.xml:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.xyz.broadcasts.MainActivity">
<Button
android:id="#+id/sendButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="SendOutBroadcast"
android:text="Send Broadcast"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
In your case your activity Intent should be like this:
Intent intent = new Intent();
intent.setAction("com.example.xyz.broadcasts");
intent.putExtra("KeyName","code1id");
intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
intent.setComponent(
new ComponentName("com.pkg.AppB","com.pkg.AppB.MainActivity"));
sendBroadcast(intent);
Try this may help you or visit for more information.
NOTE - This may be not going to work in Android O because in Android O implicit broadcast are ban as mentioned Here. (Also credits to you #Muhammad Arslan Maqsood)
i found the issue: issue is not with code, actually Android O disabled the feature "Implicit broasdcast". see this
I have a broadcast receiver I am using to display some notification. I can call it and have it be correctly triggered using ADB. But calling it from within another app does nothing.
The receiver does live in/on a Android Wear app/device.
Receiver
<receiver android:name=".NotificationReceiver" android:exported="true">
<intent-filter>
<action android:name="site.com.app.SHOW_NOTIFICATION" />
</intent-filter>
</receiver>
Call from ADB
./adb -s SERIAL shell am broadcast -a site.com.app.SHOW_NOTIFICATION
Call from App
Intent i = new Intent();
i.setAction("site.com.app.SHOW_NOTIFICATION");
i.putExtra("contentText", "Some Text");
sendBroadcast(i);
I'm not sure why it would work from ADB but not from another App, any ideas?
I don't know exact your code but you can try below code which I have made for you.

I made a splash layout, that last for a time and then other activity should be loaded,alone it works perfectly, but when it's connected to other activity, it shows blank screen.

You should use timer on splash screen instead of for(int i = 0;i< 100000000;i++); which will wait for some time suppose 5 sec and than load another Activity.
package andy.propaganda;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
/**
* Created by Andrew on 2/4/2016.
*/
public class Splash extends Activity {
//welcome animation
ImageView loading_img;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
loading_img = (ImageView)findViewById(R.id.loading_view);
final Animation animatable = AnimationUtils.loadAnimation(this, R.anim.welcome_screen_anim);
loading_img.setAnimation(animatable);
new Timer().schedule(new TimerTask() {
#Override
public void run() {
// your task
Intent intent = new Intent(this, shit.class);
intent.putExtra("jhjh", 8);
startActivity(intent);
}
}, 5000);
}
}
RxJava solution:
Observable.empty().subscribeOn(AndroidSchadelurs.mainThread()).delay(500, TimeUtils.MILISECONDS).subscribe(this::startActivity(this, new Intent));
First of All dont use for Loop for waiting time instead of That use Handler with something like this :
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
startActivity(new Intent(Splash.this, shit.class));
finish();
}
}, 500);
Then remove this line from your manifest.xml :
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Rest of your code seems ok :)
Also take look at this link which well-explained about Splash Screen.
I searched a lot for this question and tried everything mentioned on the internet but still couldn't find a solution. My widget gets installed but does not update on clicking. I have not created a default activity for it.
My problem is that my action on clicking the button is not changing.
Here is my code:
//Android manifest

Starting Android 3.1, your app must have at least one Activity that the user can launch before it will receive any broadcasts etc.
Since you don't have an Activity, your widget's broadcast probably isn't received because the system thinks your app is in a stopped state. Try adding an Activity.
