Question

I'm doing my college project which was Parental Control app. In that I'm creating a Custom Receiver. I'm tested that app in jelly bean,kitkat,lollipop, marshmallow, naughat ,oreo. But it only works in jelly bean and kitkat. I'm tried reading all solutions in stackoverflow. Please give solution for me!

@amitava I have tried it also. And also I have tried many ways but no solution found. — MnkDude, Feb 18 '19 at 19:35
I work with Nougat and Oreo(Go), and I used BroadcastReceiver. My code is little different. Can I post that as answer? — amitava, Feb 18 '19 at 19:41
@amitava Thank you for your interest. Please post that answer. — MnkDude, Feb 19 '19 at 15:54
Just before doing that let me confirm one more thing. Would you also remove android:permission="" and check. Finally what I want is — amitava, Feb 19 '19 at 18:03

I found this; it might be part of the issue. Are you getting any errors?

I have removed GET_TASKS and run the app but same problem exists. – MnkDude Feb 16 '19 at 19:09
Error not occured in API level 16. But in later API levels I can see too many Red lines in Logcat but I can't understand it. – MnkDude Feb 16 '19 at 19:11
Can you put that Logcat messages in the code in your question? – amitava Feb 16 '19 at 19:41
@amitava Kk I will include logcat. – MnkDude Feb 17 '19 at 13:01

Please try with this.

<receiver
        android:name=".MyReceiver"
        android:enabled="true"
        android:exported="false"
        >
        <intent-filter>
            <action android:name="StartupReceiver_Manual_Start"/>
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>
    </receiver>

and let me know.

After spending a week in this issue I have found solution for this. What I put before (which is not working)...

getApplicationContext.sendBroadcast(new Intent("StartupReceiver_Manual_Start"))

Now I just changed.

MyReceiver mr=new MyReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("StarctupReceiver_Manual_Start");
registerReceiver(mr,intentFilter);
getBaseContext().getApplicationContext().sendBroadcast(new Intent("StarctupReceiver_Manual_Start"));

I don't know why it is working but it works.If anyone know the reason please comment. Thanks for all who tried to solve this issue.
