OnActivityResult get null as the intent passed even though I sent an intent

I have two activities. The second activity is called from the first using startActivityForResult(intent,request_code).
In the second activity I have this code:
Intent i = getIntent();
i.putExtra("data" , some data);
setResult(Activity.RESULT_OK,i);
finish();
Then, to get the data in the first activity I use this code:
#Override
protected void onActivityResult(int requestCode,int resultCode,Intent intent)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode==this.uploadRequestCode && resultCode == Activity.RESULT_OK)
{
data = intent.get("data")
}
I start the activity this way:
Intent uploadIntent = new Intent(this,uploadActivity.class)
startActivityForResult(uploadIntent,this.uploadRequestCode)
The problem is that the result code I get is RESULT_CANCELLED even though I set RESULT_OK.
NOTE
I am not talking about a situation when back button is pressed.
UPDATE
I found out that the intent I get in onActivityResult() is null even though I sent an intent, that's why the result code was RESULT_CANCELLED.
Anyone knows why the intent is null?

Maybe this can help you out, something from a project that I have
This how I do start my activity
Intent intent = new Intent(FirstActivity.this, ActivityThatReturnInfo.class);
startActivityForResult(intent, 1);
This is from the activity that I want to return some value
Intent returnIntent = new Intent();
returnIntent.putExtra("VAR",someInfo);
setResult(Activity.RESULT_OK,returnIntent);
finish();
This is on the activity that as started the one that is waiting for the information
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
switch (requestCode)
{
case 1:
if(resultCode == Activity.RESULT_OK)
{
String result = data.getStringExtra("VAR");
// Code to do
}
break;
default:
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null)
{
if(result.getContents() != null)
{
// Code to do
}
}
break;
}
}

Starting SecondActivity from FirstActivity
Intent i = new Intent(this, SecondActivity.class);
startActivityForResult(i, 100);
Sending data to FirstActivity from SecondActivity
Intent intent= new Intent();
intent.putExtra("result",result);
setResult(RESULT_OK,intent);
finish();
getting result in FirstActivity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == 100 && resultCode == Activity.RESULT_OK){
String result=data.getStringExtra("result");
Log.e("Result",result);
}
}
Edit:
Change your code to below and try once.
While sending intent from SecondActivity to FirstActivity Intent i = getIntent(); to Intent intent= new Intent();

onActivityResult Intent is null when passing Intent from Adapter

I am facing a strange issue while returning to an Activity with a Result, I am passing an Intent for startActivityForResult from an Adapter like this :
Intent i = new Intent(activity, EditInfoActivity.class);
i.putExtra("id", list.get(position).getID());
activity.startActivityForResult(i, 100);
and in second Activity i.e. in EditInfoActivity in my case on a Button click I am setting Result for first activity like this:
Intent i = getIntent();
i.putExtra("isDataChange", isDataChange);
setResult(100, i);
finish();
In Activity's onActivityResult method I am able to get result code but getting Intent null.
Why? anybody have any idea on this please share.
in Activity:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 100) {
//Here data is null and app crash
if (data.getExtras() != null && data.getBooleanExtra("isDataChange", false)) {
recreate();
}
}
}

First, you need to start the Activity with a REQUEST_CODE:
// Here we set a constant for the code.
private final int REQUEST_CODE = 100;
Intent i = new Intent(activity, EditInfoActivity.class);
i.putExtra("id", list.get(position).getID());
activity.startActivityForResult(i, REQUEST_CODE);
Then you need to send RESULT_OK when finishing EditInfoActivity:
Intent i = getIntent();
i.putExtra("isDataChange", isDataChange);
setResult(RESULT_OK, i);
finish();
Then handle the result on your first activity with this:
Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// REQUEST_CODE is defined as 100
if (resultCode == RESULT_OK && requestCode == 100) {
// do process
}
}

setResult TAKES RESULT_CODE instead of REQUEST_CODE.
Replace your code with this, May be it will solve your problem.
setResult(RESULT_OK, i);
And in yout onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
//Here data is null and app crash
if (data != null && data.getBooleanExtra("isDataChange", false)) {
recreate();
}
}
}

Two mistakes. You are passing the intent that was used to launch the activity you are finishing. Use new Intent() instead.
When setting activity result you should use result codes, not a request code setResult(RESULT_OK) alternatively RESULT_CANCELED and handle the response accordingly.

how to receive data in previous activity in Android

I want to receive data in previous Activity from next activity like (1 <--- 2 ). I tried but data is not received from second to first activity .
This is First Cativity
Intent i = new Intent(CustomActionActivity.this, Edit_Post.class);
i.putExtra("ActivityId", getItemActivity);
i.putExtra("Vessel", strVesselName);
i.putExtra("HashTag", strHashTag);
i.putExtra("RemarkTitle", strRemark);
i.putExtra("ShortRGN", strShortTypeRGN);
i.putExtra("VessId", strvesselid);
startActivity(i);
This is second Activity
Intent intent = getIntent();
strActivityId = intent.getStringExtra("ActivityId");
strVesselName = intent.getStringExtra("Vessel");
strHashTag = intent.getStringExtra("HashTag");
strRemark = intent.getStringExtra("RemarkTitle");
strShortRGN = intent.getStringExtra("ShortRGN");
strVessId = intent.getStringExtra("VessId");
img_AddPostAudio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(Edit_Post.this, EditRecord.class);
i.putExtra("EditVesselId", strVessId);
i.putExtra("EditActivityId" , strActivityId);
startActivity(i);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CODE)
{
String audioString=data.getStringExtra("AUDIO_STRING");
Log.e(" audioString "," = "+audioString);
}
}
This is Third Activity
Intent intent = getIntent();
vesselId = intent.getStringExtra("EditVesselId");
strActivityId = intent.getStringExtra("EditActivityId");
Intent intent=new Intent(EditRecord.this, Edit_Post.class);
intent.putExtra("AUDIO_STRING",newAudioFile);
setResult(REQUEST_CODE, intent);
finish();

do this when you are calling the second activity
Intent i = new Intent(CustomActionActivity.this, Edit_Post.class);
i.putExtra("HashTag", strHashTag);
startActivityForResult(i, REQUEST_CODE);
Now you need to set the result what you want on CustomActionActivity
e.g.
Intent intent=new Intent();
intent.putExtra("MESSAGE",message);
setResult(REQUEST_CODE,intent);
finish();
Now you will get this data to the your first activity
e.g.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CODE)
{
String message=data.getStringExtra("MESSAGE");
textView1.setText(message);
}
}
let me know in case of any issue

Use SharedPreferences
Store the data in a SharedPreference and access it in from the SharedPreference in the other activity.
Add the data to the SharedPreference in the onStop for the 2nd Activity and access it in the onCreate of the other Activity
#Override
public void onStop(){//Where you wish to insert data
SharedPreferences data=getSharedPreferences(PREFS_FILE,0);
SharedPreferences.Editor editor= count.edit();
editor.put("data","DATA");
editor.apply();
super.onStop();
}
in onCreate() of the other Activity:
SharedPreferences data = getApplicationContext().getSharedPreferences(PREFS_FILE, 0);
String dataString=data.get("Data",0);
Hope this helps. Cheers.

I am doing this way its works for me:
Activity 2:
public void onBackPressed() {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.putExtra("MESSAGE", strtext + "");
setResult(2, intent);
if (isclose) {
finish();
} else {
super.onBackPressed();
}
}
}
Activity1:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String sSuName = data.getStringExtra("MESSAGE");
//txtfavouratecount.setText(sSuName);
}
in Your onclick listener
Intent itemintent = new Intent(context,your target Activity.class);
Bundle b = new Bundle();
b.putStringArray("iarray", Qtag);
b.putInt("mflag", 0);
itemintent.putExtra("android.intent.extra.INTENT", b);
startActivityForResult(itemintent,2);

I would do something like this:
In Activity A:
private static final int REQUEST_CODE = 9001;
Intent intent = new Intent(this, ActivityB.class);
startActivityForResult(intent, REQUEST_CODE);
In Activity B:
Intent data = new Intent();
data.putExtra("key", parameter);
setResult(CommonStatusCodes.SUCCESS, data);
finish();
And finally, in the Activity A, receive result:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE) {
if (resultCode == CommonStatusCodes.SUCCESS) {
if (data != null) {
String result = data.getStringExtra("key");
}
} else {
//Error to receive data
}
}
else {
super.onActivityResult(requestCode, resultCode, data);
}
}
Good luck!

How to return string from activity started for result

I have started Activity for result, but how to return string like parameter from that activity ?

just use following code block:
Intent intent=new Intent();
intent.putExtra("RESULT_STRING", string);
setResult(RESULT_OK, intent);
finish();
get value from this intent in onActivtyResult method in calling activity:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CREATE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
//Use Data to get string
String string = data.getStringExtra("RESULT_STRING");
}
}
}

You just need to putExtra in the intent and the call setResult(),
Intent data = new Intent();
data.putExtra("myobj", value);
setResult(Activity.RESULT_OK, data);

The documentation says it all. You set the result by calling setResult and you read it in the onActivityResult method.

startActivityForResult and Intents Extras, it seems extras are not pushed back

I have this code:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
intent.setData(ContactsContract.Contacts.CONTENT_URI);
intent.putExtra(EXTRA_ONLINE_ID, (String) v.getTag());
startActivityForResult(intent, PICK_CONTACT);
Then on response:
public void onActivityResult(int reqCode, int resultCode, Intent data) {
switch (reqCode) {
case (PICK_CONTACT):
if (resultCode == Activity.RESULT_OK) {
try {
Uri contactData = data.getData();
String onlineid = data.getStringExtra(EXTRA_ONLINE_ID);
} catch (Exception e) {
e.printStackTrace();
}
}
break;
}
super.onActivityResult(reqCode, resultCode, data);
}
the onlineid variable is null. How can I pass a value and then to receive it back?
EDIT
I even tried,
Bundle extras = data.getExtras(); // returns null

This is done by design; system activities will not send back the extras with which they're called, so you have to manage the data elsewhere.
Luckily, the resultCode parameter is fully controlled by yourself, which means that you can use it to index your data.
private final int PICK_CONTACT = 0;
private Bundle[] myDataTransfer = { null };
...
Bundle myData = new Bundle();
myData.putString(EXTRA_ONLINE_ID, (String) v.getTag());
myDataTransfer[PICK_CONTACT] = myData;
// create intent and all
startActivityForResult(intent, PICK_CONTACT);
...
public void onActivityResult(int reqCode, int resultCode, Intent data) {
if (resultCode == PICK_CONTACT) {
Bundle myData = myDataTransfer[resultCode];
String onlineid = myData.getString(EXTRA_ONLINE_ID);
}
}
I'm not a Java programmer, there must be a nicer way to implement a map of Bundles, but this works :)

ok Check if your Activity android:launchMode is configured as SingleTask or SingleInstance! that must be the problem :)

The EXTRA_ONLINE_ID field will have to be set in the activity that you launched using setResult. If it's not setting that value in the returned Intent (which is different from what you sent) then you will get a null value.

I was running into some problems with this as well.
Instead of this line
intent.putExtra(EXTRA_ONLINE_ID, (String) v.getTag());
Try
intent.putExtra(EXTRA_ONLINE_ID, "" + v.getTag());
