How to update activity after image upload in Android

How to update activity after image upload in Android - android

I have an activity where the user can update some data related to his profile (for example, his name) and he can also upload a new profile image.
After the update operation, the user is redirected to a new activity.
The problem is that when the user comes back to his profile activity, the showed image is still the old one and not the new one while the name updated correctly.
In order to see the new profile image, the user needs to close the app and open is again.
How can I solve this problem?
I use a function updateInfo(), but it seems to not work as I would like.
Can you help me, please?

When you turn back to your profile activity your application's task stack is bringing back your profile activity which is already in memory. So you should inform your profile activity that it was updated. In the onStart callback of your profile activity check if it is updated. If so load the new image. In short put your upDateInfo() method inside onStart().

After you update the information, in callback method onResponse you need to call updateInfo() to make an update on your UI after update of information is successfully finished. Make sure you provide new values from server especially to static variables because they will keep values as long as app is live. If you don't update them with new values they will keep old ones.
Currently on that way you are trying to update informations only in onCreate() which is called when Activity needs to be created. In this scenario it is when you exit and enter app again only by pressing Back button while on Home button it will not work as well until app is destroyed by OS.
You could also use onResume method which is called after Activity is returned from pause and that will happen when you create a new Activity upon already exiting one.

how to set wallpaper as lockscreen or both(home and lock)?

I have done implementing "set wallpaper as home screen".but im not getting how can I set wallpaper as lock screen and both(home and lock).in following code "if" part is for setting as homescreen..rest is for "lock" and "both(home and lock)"..what will the logic for it to set wallpaper as lock and both(home and lock).?

You wanna just set Flags for various Wallpaper Options.
Flags like...
WallpaperManager.FLAG_LOCK | WallpaperManager.FLAG_SYSTEM : for both Screen
WallpaperManager.FLAG_SYSTEM : for Home Screen
WallpaperManager.FLAG_LOCK :for Lock Screen
Thanks :)

How to avoid the restarting the values on startActivity from a activity?

I am working on a filter activity in which there are 3 images at the bottom. By default, image 3 will be selected as it is the last one that will be clicked.
This same activity contains Latitude and Longitude which will be sent to next activity to fetch nearby locations.
The problem that I am facing is that among those 3 images when I select a filter for Image 1 and select the image 2, the activity gets restarted and because of this, the lat and long values are reset to 0.0 and 0.0 respectively.
Code -
public class MainActivity extends AppCompatActivity implements FiltersListFragment.FiltersListFragmentListener, EditImageFragment.EditImageFragmentListener {

}
May I know how to either stop restarting the activity and select the image to get its preview to apply filters or how to save the lat and long values so that it won't get reset when the activity restarts?

If the value should be held across activity restarts you should be using an activity or shared preference.
Basically in your onCreate, load the values and assign them to your Textview (or other component). When they change just update the preference value.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Load the lat/lng
SharedPreferences preferences = getPreferences(MODE_PRIVATE);
double lat = preferences.getDouble("latitude", 0);
double lon = preferences.getDouble("longitude", 0);
}
Then where you have your application update that value simply update the preference value.
private void updatePreference(double lat, double lng) {
SharedPreferences preferences = getPreference(MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putInt("latitude", lat);
editor.putInt("longitude", lon);
editor.commit();
}
That will hold your values and allow you to update/interface with them across activity restarts.

Finally found a solution, the problem was with the android:launchMode in the manifest.

Android cannot bind to service (In App-Billing)

I'm trying to implement in app-billing in my application, but I have a little problem with it. I'm using the example from android developer's site and everytime I start the activity which will connect to the billing service it's showing me a dialog that I cannot connect to server and when I press learn more it's going to a web page which is explaining me to update my android market app, but it's already the latest one. And the other thing, before implementing the code on my application I create a test application where I can connect with the same code and I don't get problems. But in my application I can't do that. Is there any connection with the developer api key, which you can use only in one application or something like that. Because I'm using the same for test and real app.
And here is my code if you can see something which is not really like it should be :

And here is how I'm declaring the service in manifest file :
<service android:name="BillingService" />
<receiver android:name="BillingReceiver">
<intent-filter>
<action android:name="com.android.vending.billing.IN_APP_NOTIFY" />
<action android:name="com.android.vending.billing.RESPONSE_CODE" />
<action android:name="com.android.vending.billing.PURCHASE_STATE_CHANGED" />
</intent-filter>
</receiver>
Any suggestions how to connect to the market?

I had the same issue and probably your mistake is the same as mine. I was using a TabHost in my activities and I find out that TabSpec cannot bind to services. So check this :
Using getApplicationContext().bindService instead of just bindService
on your activity solves the problem as it is using the higher level
application context.

Can't you debug through that code? Probably, mBillingService.checkBillingSupported() returns false, caused by failing BillingService.bindToMarketBillingService().

i was facing problem like that on my sony ericssion w8 2.1 android device
what i did are the following :
1) getApplicationContext().bindService (as android-droid said)
2) reset my mobile and downloaded apk for market 2.3.4 version and installed it
3) then open the market app on mobile and clicked accepted and when the app i quitted
4) rerunned the app it was working fine
note: before doing this i tested my app on other device using market version 3.x and it was working so i did all these things ...
