before i'm so sorry if my post maybe duplicated, but i have another case in this problem, i wanna show an image that i capture from camera in ImageView and after that i save it or upload it into my json file, but after i take the picture, it's stopped in Log.i ("Error", "Maybe Here");
no error in my code but the image cant saved into thumbnail ImageView
Here is my code, i'm using Asyntask

I think your activity just got restarted you need to put below code in manifest where you declare. and save your uri on saveInstanceState and restore it on onrestoreinstancestate. it will be resolve your issue
android:configChanges="orientation|keyboardHidden|screenSize"

Use this lib,Provides support above API 14

How to prevent onCreate when application is resumed?

I've made a music player usim MediaPlayer. When I close the app the song keeps playing but when I resume, onCreate is called everything starts again and previous song also keeps playing. So if now I start new song, both the songs play even though there's only one MediaPlayer variable. Why is onCreate called when app is reopened. What is the way to prevent it?
EDIT: Note that xml file also gets reset. PLus I loose control over song playing before leaving the app.

As you know : onCreate(), onStart() and onResume() will be called when you start an Activity.So to avoid onCreate recall, you can use a boolean in your onCreate method for example isActivityReopened that is set to false, then set to true in the first use of onCreate. Here an example you can inspire from it :
#Override
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
// Other stuff
if (!isActivityReopened) {
// Run what do you want to do only once.
// To avoid onCreate() if it will be called a second time,
// so put the boolean to true
isActivityReopened = true;
}
}

In your code you are not checking whether the mediaplayer was playing or not every time you choose a new song.
if(mediaPlayer.isPlaying())
{mediaplyer.stop()}
you need to stop it and then reset it again.
try as well to set the launch mode in the Manifest file of the activitg tag to be singleTask.
<activity
android:name=".MainActivity"
android:launchMode="singleTask">
My advice for you if you want yourself to get out of all this is to use a bound service. It will help you managing the mediaplayer states and will keep running in the background. This great tutorial might help.

This is because in your getView() you do not consider the position. You always set the bitmap to image2 which is the most recent bitmap: holder.image.setImageBitmap(image2);
I think you misunderstood how get view works. The getView() method is called for each item in the list when you notifyDataSetChanged().
The solution is to keep reference to the different bitmaps in a list (or elsewhere.. i am just giving a possible solution),
List<Bitmap> images = new ArrayList<>();
When you get the image from the result, add it to the images list.
image2 = Bitmap.createScaledBitmap(thumbnail, imageWidth , imageHeight, true);
images.add(image2)
Finally, setImageBitmap based on the position of the item during getView()
holder.image.setImageBitmap(images.get(position));

save state of changed database in android application

I am working on an android app, in which the first page is a homepage. On clicking on any item on the homepage, the user can view details in that item. The details are taken from an sqlite database and can be accepted or rejected in the app by the user. On accept or reject by the user, the detail gets deleted from the list of details. But, on clicking back button from the details page, when the user reaches the homepage again, there occurs this problem that when the user clicks on the same item again, it shows all the details without saving state.
E.g. if my item1 has 10 details within it..i view all the 10 details in the details page..then accept 2..so total remain 8..but when i click back and reach the homepage and again click on item1, it shows all 10 again...and does not record the change which occured when 2 were accepted.
How can this be solved?

Hard to find database calls in your code. Some general guidelines:
First you need to encapsulate all calls to the Database in separate threads.
Always close your cursors and DB connection after you're finished.
Best would be to use AsyncTask. Check out some tutorials for using SQLite with AsyncTask - it will handle the separate Thread automatically for you.
Second - read about the Activity Stack, so that what #Peter tells you makes sense.

multiple attachments but only selected ones

I have my main view with images and checkboxes associated with them and a send email button. When I click on the checkboxes and select send email button I should be redirected to the email page where the selected images must be attached. Here is my code.
please help me out

Check with your xml & this attribute to the list android:choiceMode="multipleChoice" and see.
