Question

I need my android app to be in background mode after a phone restart/power on.

Currently I am using the following code, so that my app successfully gets launched after a phone restart/power on.

AndroidManifest.xml:

<receiver android:enabled="true" android:name="my_package.BootUpReceiver" 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>

BootUpReceiver.java:

public class BootUpReceiver extends BroadcastReceiver
{
    private static SharedPreferences aSharedSettings;

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        aSharedSettings = context.getSharedPreferences("MyPreferences", Context.MODE_PRIVATE);
        boolean isUserLoggedIn = aSharedSettings.getBoolean(Key.AUTHENTICATED, false); 
        if(isUserLoggedIn) 
        {
            Intent aServiceIntent = new Intent(context, MyHomeView.class);
                    aServiceIntent.addCategory(Intent.CATEGORY_HOME);
            aServiceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(aServiceIntent); 
        }
    }
}

As I said above, my app successfully gets launched after a phone restart/power on.

However, after the phone restart/power on, my app was in foreground mode. But I need my app to be in background mode.

Can anyone please say, how to make an app to be in background mode after a phone restart or power on.

I even tried by changing the intent category to

<category android:name="android.intent.category.HOME" />

But no use in it. Can anyone please help me?

Thanks.

Answer 1

The suggestion which Leonidos replied is correct.

However, Just a workaround for this:

In my BootUpReceiver, I had a seperate boolean flag for this! (Its a bad way. but just a workaround)

SharedPreferences.Editor aPrefEditor = aSharedSettings.edit();
aPrefEditor.putBoolean(Key.IS_DEVICE_RESTARTED, true);
aPrefEditor.commit();

In Oncreate method of MyHomeView:

boolean isDeviceRestarted = aSharedSettings.getBoolean(Key.IS_DEVICE_RESTARTED, false);
if(isDeviceRestarted)
{
    SharedPreferences.Editor aPrefEditor = aSharedSettings.edit();
    aPrefEditor.putBoolean(MamaBearKey.IS_DEVICE_RESTARTED, false);
    aPrefEditor.commit();
    moveTaskToBack(true);
}

Thanks
