StartActivityForResult between 2 apps doesn't return any value to the first App

Let's say I have App A and App B.
In app A, I launch an intent to start App B in this way.
Intent intent = new Intent("com.example.myAppBAction");
Bundle bundle = new Bundle();
bundle.putString("anId", id);
intent.putExtras(bundle);
startActivityForResult(intent, myRequestCode);
Then in App B, I receive all my data and after doing some work I return a result this way.
#Override
public void onBackPressed() {
super.onBackPressed();
Intent i = new Intent();
int codeWorkDone;//this is valued between 2 or 3
i.putExtra("FirstResult", anInteger);
i.putExtra("SecondResult", anotherInteger);
setResult(codeWorkDone, i);
finish();
}
Eventually in my onActivityResult I need to print all the extras put in App B, as it follows:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case myRequestCode:
StringBuilder result = new StringBuilder();
result.append(resultCode + "\n");
if (data != null){
Bundle b = data.getExtras();
if (b != null) {
for (String key : b.keySet()) {
result.append(key + " : " + (b.get(key) != null ? b.get(key) : "NULL"));
}
}
}
Log.d("esito", result.toString());
break;
}
}
The problem here is that the requestCode is correct, but I received back a resultCode which is 0 (remember that from app B is set between 2 or 3) and my data is null.
Any hint on this one?

What forces android activity to be destroyed when launching another activity

I'm trying to add in-app purchases and when I call OpenIabHelper::launchPurchaseFlow function:
I see Google Play purchase window
onStop and onDestroy are executed in my main activity without calls to onActivityResult
So in the end I left with GooglePlay window and my dead app
I tried to start another activity via startActivityForResult and it worked fine
(nothing was destroyed and onActivityResult was called), so it seems that problem is with OpenIAB library
Therefore there's my question:
What can possibly force my activity to be destroyed after calling OpenIabHelper::launchPurchaseFlow ?
It doesn't seem to be system because it has enough memory and as I said startActivityForResult works fine.
Also there's no exceptions being trown so I'm puzzled
Any help would be appreciated
MyActivity.java
public class MyActivity extends AppCompatActivity {
private OpenIabHelper m_helper;
private Boolean m_bOpenIabInitialized = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OpenIabHelper.Options.Builder builder = new OpenIabHelper.Options.Builder()
.addAvailableStores(new GooglePlay(this,null))
.addPreferredStoreName(OpenIabHelper.NAME_GOOGLE)
.setStoreSearchStrategy(OpenIabHelper.Options.SEARCH_STRATEGY_INSTALLER_THEN_BEST_FIT)
.setVerifyMode(OpenIabHelper.Options.VERIFY_SKIP)
.setCheckInventory(false);
m_helper = new OpenIabHelper(this, builder.build());
m_helper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
m_bOpenIabInitialized = result.isSuccess();
}
});
}
public void onListViewItemClicked(String sku, String payload) {
if (m_bOpenIabInitialized == null || !m_bOpenIabInitialized) return;
m_helper.launchPurchaseFlow(this, sku, 10001, null, payload);
}

Have you tried changing the activity's launchMode? Maybe the singleTop launch mode will preserve your activity:
<activity
android:name=".MyActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar"
android:configChanges="orientation|screenSize|keyboardHidden|screenLayout"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
You can find more about launch modes here:

Move your receiver XML in your manifest to within the application tags.
<application

Android referral tracking not working with Google play

I am trying to implement referral tracking on downloads from the Google play.
Before uploading to Google Play, when I tried testing the app using below script, its working fine and i am getting referral string.
adb shell
am broadcast -a com.android.vending.INSTALL_REFERRER -n <my.myPackage>/.<path.up.until.my.CustomBroadcastReceiver> --es "referrer" "utm_source%3Dentity%26utm_medium%3Dsocial%26utm_campaign%3Dwo_referrer%26referrerId%3D173%26entity%3Dfacebook%26email%3Dmideeshp%40email.com"
After running this code, I am decoding the referral string and my server getting updated according to the referral string. But when I deployed this app to Google play, I am not getting any referral string from Google play. I am using Google Analytics V2 for both analytic tracking and referral tracking.
Below one is my custom BroadcastReceiver.
public class InstallReferrerReceiver extends BroadcastReceiver {
private static final String TAG = "InstallReferrerReceiver";
#Override
public void onReceive(Context context, Intent intent) {
HashMap<String, String> values = new HashMap<String, String>();
try {
if (intent.hasExtra("referrer")) {
Toast.makeText(context, "Inside app refferal", 5000).show();
String url = intent.getStringExtra("referrer");
final String referrer = URLDecoder.decode(url, "UTF-8");
String referrers[] = referrer.split("&");
int i = 0;
for (String referrerValue : referrers) {
String keyValue[] = referrerValue.split("=");
values.put(URLDecoder.decode(keyValue[0], "UTF-8"),
URLDecoder.decode(keyValue[1], "UTF-8"));
Log.i("" + i, keyValue[0] + "=" + keyValue[1]);
}
new AsyncTask<String, String, JSONObject>() {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected JSONObject doInBackground(String... params) {
// TODO Auto-generated method stub
String referrerUrl = "MyserverUrl?action=storerefer&" + referrer;
Log.i("purl address", referrerUrl);
JSONObject json = RestJsonClient.connect(referrerUrl);
return json;
}
#Override
protected void onPostExecute(JSONObject result) {
// TODO Auto-generated method stub
try {
if (result == null) {
Log.i("json null", "12");
} else {
String status, error;
status = result.getString("status");
error = result.getString("error");
if (status.equals("success")) {
Log.i("referrer", "referrer status success");
}
if (status.equals("failure")) {
Log.i("referrer", "referrer status failure");
}
}
} catch (JSONException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
super.onPostExecute(result);
}
}.execute();
}
} catch (Exception e) {
}
}

What should I do to get referral string from Google Play ?

you can write this simple reciever:
public class DetectInstall extends BroadcastReceiver{
private String referrerId;
#Override
public void onReceive(Context context, Intent intent) {
if ((null != intent)
&& (intent.getAction().equals("com.android.vending.INSTALL_REFERRER"))) {
Log.e("Message", "App is getting installed first time..");
referrerId = intent.getStringExtra("referrer");
}
}
}
then in manifest add the receiver tag inside the application like this :
<application
android:hardwareAccelerated="true"
android:icon="#drawable/ic_bmg"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/AppTheme" >
<receiver
android:name=".DetectInstall"
android:exported="true" >
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
then you will need to send the referrer parameter to the google playstore URL Like this :
https://play.google.com/store/apps/details?id=you.package.name&hl=en&referrer=you will get this first time when you install app
referrer field is required, whatever string u pass in referrer field you will get it in the broadcast reciever

GCM no receive messages in 2.3.6 but it's ok in 4.1.2

The problem is only with android 2.3.6 .
With 4.x, there isn't any problem, the receiver it's ok.
I have received the registration ID with 2.3.6 but the messages are never received.

} else {

}
return false;
}
return true;
}

Check the Google play services version number and there is a pretty defined method to check Google play services a availability

Latest release of gcm using google play is very easy to implement and can be used for longer time.
See this tutorial. Hope it might help.
