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

setOnItemClickListener crash in AutoCompleteTextView

I have an android application. In this app I used a AutoCompleteTextView with custom SimpleCursorAdapter. In AutoCompleteTextView addTextChangedListener's onTextChanged method,
I am using below Code
SearchFeedResultsAdaptorCustomer mSearchViewAdapter = new SearchFeedResultsAdaptorCustomer(this.getActivity(), R.layout.searchview_customer, null,
columns, null, -1000);
textView = (AutoCompleteTextView) mRoot.findViewById(R.id.search_box);
textView.setAdapter(mSearchViewAdapter);
textView.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
try {
loadData(s.toString());
} catch (JSONException e) {
e.printStackTrace();
}
textView.setAdapter(mSearchViewAdapter);
}
#Override
public void afterTextChanged(Editable s) {
}
});
And the loadData method is:
private void loadData(String searchText) throws JSONException {
ArrayList<JSONObject> filterCustomers = new ArrayList<>();
if (searchText == null || searchText == "") {
filterCustomers = prgmNameList;
} else {
int i = 0;
for (JSONObject customer : prgmNameList) {
if (customer.getString("fullName").toUpperCase().contains(searchText.toUpperCase())) {
filterCustomers.add(customer);
}
}
}
Log.e("searchhh", "load data" + filterCustomers.size());
MatrixCursor matrixCursor = convertToCursor(filterCustomers);
mSearchViewAdapter.changeCursor(matrixCursor);
}
private MatrixCursor convertToCursor(ArrayList<JSONObject> customerList) throws JSONException {
MatrixCursor cursor = new MatrixCursor(columns);
int i = 0;
for (JSONObject customer : customerList) {
String[] temp = new String[8];
i = i + 1;
temp[0] = "" + i;
temp[1] = String.valueOf(customer.getString("accountNumber"));
temp[2] = String.valueOf(customer.getString("address"));
temp[3] = String.valueOf(customer.getString("email"));
temp[4] = String.valueOf(customer.getString("fullName"));
temp[5] = String.valueOf(customer.getString("mobile"));
float point;
if (customer.getString("earn_point") == null) {
point = 0;
} else {
point = Float.parseFloat(customer.getString("earn_point").toString());
}
temp[6] = String.valueOf(point);
temp[7] = String.valueOf(customer.getString("uid"));
cursor.addRow(temp);
}
return cursor;
}
It shows data as list of drop down but when I clicked a list item, I got following error.
Here is my click item method:
textView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("Position", "pos:"+position);
Cursor cursor = (Cursor) parent.getItemAtPosition(position);
//or
//Cursor cursor = (Cursor) parent.getItem(position);
//MatrixCursor matrix = (MatrixCursor)parent.getItemAtPosition(position);
cursor.moveToPosition(position);
Log.e("Position", "pos:"+cursor.getCount());
String feedName = cursor.getString(1);
searchView.setQuery("", false);
searchView.clearFocus();
name.setText(cursor.getString(4));
mobile.setText(cursor.getString(5));
email.setText(cursor.getString(3));
point.setText(cursor.getString(6));
account.setText(cursor.getString(7));
usepontHidden.setText(String.valueOf(0));
}
});
Here is the error message:

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.

Get the item index of a listview and delete it on the listview and on my database

I'm now currently working on a project that lets the user view the list of a certain table and has the privilege of either editing or deleting it.

I hope anyone could help me on this. I really need a help right now. Thanks! :)

You can use this
sql_lite_db_obj.delete(tablename, whereClause, whereArgs)
For your convenience i edited my answer
public void clickHandler(View v) {
if (v.getId() == R.id.deleteOrder) {
int _id = 0;
try {
_id = (Integer) v.getTag(R.id.orderTitle);
} catch (Exception e) {
e.printStackTrace();
}
dh.delete(DatabaseHelpere.TableNAME, "_id=?",new String[] { String.valueOf(_id) });
}
}

Manually create your app directory in sd card and then save image in that directory.
You can try following snippet.
String root=Environment.getExternalStorageDirectory().toString();
File myDir = new File(root+"/demo_image");
if(!myDir.exists())
{
myDir.mkdir();
}
String fname = "Image"+String.valueOf(System.currentTimeMillis())+".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
photo.compress(Bitmap.CompressFormat.JPEG,100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
