Android: start activity on boot complete

Question

I have tried this on a few android phones with no luck (i did start the app once).

This was mostly generated from android studio 1.3.2 and from some questions like this and that and the other.

Perhaps someone can point out what i am doing wrong.

Thanks

edit: moved receiver inside app, but no joy.

edit2: added missing permissions for receiver. now seems to work on a nexus 4. but not on the kindle fire or the at&t tablets. although it seems to come right away if i press the circle icon on the azpen.

edit3: seems to work sometimes on the fires now.

package acme.startup;
import android.content.*;
public class BootReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            Intent activityIntent = new Intent(context, MainActivity.class);
            activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(activityIntent);
        }
    }
}

package acme.startup;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_main,menu);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id=item.getItemId();
        if(id==R.id.action_settings)
            return true;
        return super.onOptionsItemSelected(item);
    }
}

Answer 1

Every Component must be declared inside application tag into manifest. Here you declared receiver outside of application tag. Read Structure of the Manifest File.

Correct manifest wil be

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="acme.startup" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    <receiver
        android:name=".BootReceiver"
        android:label="BootReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
    </application>
</manifest>
