StartActivityForResult between 2 apps doesn't return any value to the first App

Let's say I have App A and App B.
In app A, I launch an intent to start App B in this way.
Intent intent = new Intent("com.example.myAppBAction");
Bundle bundle = new Bundle();
bundle.putString("anId", id);
intent.putExtras(bundle);
startActivityForResult(intent, myRequestCode);
Then in App B, I receive all my data and after doing some work I return a result this way.
#Override
public void onBackPressed() {
super.onBackPressed();
Intent i = new Intent();
int codeWorkDone;//this is valued between 2 or 3
i.putExtra("FirstResult", anInteger);
i.putExtra("SecondResult", anotherInteger);
setResult(codeWorkDone, i);
finish();
}
Eventually in my onActivityResult I need to print all the extras put in App B, as it follows:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case myRequestCode:
StringBuilder result = new StringBuilder();
result.append(resultCode + "\n");
if (data != null){
Bundle b = data.getExtras();
if (b != null) {
for (String key : b.keySet()) {
result.append(key + " : " + (b.get(key) != null ? b.get(key) : "NULL"));
}
}
}
Log.d("esito", result.toString());
break;
}
}
The problem here is that the requestCode is correct, but I received back a resultCode which is 0 (remember that from app B is set between 2 or 3) and my data is null.
Any hint on this one?

Error While Sending Large Sentence As SMS using Array in java using default SMS service over SIM

I am having trouble on sending SMS from APP. I the App is working Fine on some Devices like Samsung, Nokia etc. But Not working on devices like OPPO, VIVO devices. All the devices I tested was SDK29 (ANDROID 10).
ps: I am newbie here
Below is my code Sombodey please Help me.
sendSms() method is Supposed to send the sms.
private void sendSms() {
String names = name_text.getText().toString();
String s1=phone_text.getText().toString();
String s2=("Hi "+names+", You have Successfully recharged ₹ " +d1 +" to your account on "+timeStamp+". Your current balance is ₹ "+amount+" . Kindly clear your balance on time without any due. \n - Thank you! ");
try {
if (!TextUtils.isEmpty(s1) && !TextUtils.isEmpty(s2)) {
if (checkPermission(Manifest.permission.SEND_SMS)) {
SmsManager smsManager = SmsManager.getDefault();
ArrayList<String> part = smsManager.divideMessage(s2); //this is line 629//
smsManager.sendMultipartTextMessage(s1, null, part, null, null);
} else {
Toast.makeText(UserDetailsActivity.this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(UserDetailsActivity.this, "Permission denied", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Log.wtf("userDetailsActivity","Error ", e);
e.printStackTrace();
}
}
nothing happens when this method is called on the device OPPO/VIVO
but works fine on samsung
What showing on the Run is

I think the problem is with the way you declared the string.
Try without using the divide message function. Pass the arraylist directly to the sendMultipartTextMessage function

Android BroadcastReceiver not detecting SMS

I don't know what has gone wrong, but I'm having a difficult time with this one. The program is supposed to show a toast once a message is received. I have tried adding the priority in the manifest file, but it doesn't work.
The manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</application>
Broadcast Receiver
public void onReceive(Context context, Intent intent) {
Log.d("RECEIVE", "Receiving SMS");
Bundle intentExtras = intent.getExtras();
if(intentExtras != null){
Object[] sms = (Object[]) intentExtras.get("pdus");
String msgStr = "";
for(int i = 0; i < sms.length; ++i){
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);
String smsBoddeh = smsMessage.getMessageBody().toString();
String addr = smsMessage.getOriginatingAddress();
msgStr += "SMS From " + addr + "\n";
msgStr += smsBoddeh + "\n";
}
Toast.makeText(context.getApplicationContext(), msgStr, Toast.LENGTH_SHORT).show();
Log.d("RECEIVE", msgStr);
}
}

Try enabling the same..
<receiver
android:name="com.smsforwarder.smsforwarder.SMSReceiver"
**android:enabled="true">**
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>

In fact, no toast will appear, and nothing appears in the log, I think the myreceiver is not initialized ...

Move your receiver XML in your manifest to within the application tags.
<application
android:allowBackup="true"
android:icon="#mipmap/locate"
android:label="#string/app_nameprincipal"
android:supportsRtl="true"
android:theme="#style/AppTheme">

Android - Starting service by booting and wifi on

I am sorry for my bad english, I am from germany.
I try to explain my problem.
I'll start a service, if the smartphone booted and is internet connection enabled. I hope you can understand me.
This is my Autostart
public class Autostart extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {
try {
context.startService(new Intent(context, SpyService.class));
} catch (Exception ex) {
}
}
}
}
and this is my manifest

If i restart my phone and open the wlan, the service is not started. Why?

use this code in your broadcast.
public class Autostart extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
ConnectivityManager connectivityManager = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE );
NetworkInfo activeNetInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
boolean isConnected = activeNetInfo != null && activeNetInfo.isConnectedOrConnecting();
if (isConnected)
// start your service
}
}
