Android&Quickblox (api 3.2): Subscribing to push notifications

I'm not able to subscribe to push notifications. I did:
1) I created a firebase application, with the same package name as my MainActivity package name;
2) I downloaded the google-service.json file and stored it in my /app/ next to the gradle file;
3) I added the C2D and WAKE-LOCK permissions as the google guide showed;
4) I added the API-KEY in the pushnotification's setting tab in quickblox admin panel;
5) I modified the manifest as showed by the quickblox guide;
6) I added a push-notification listener and a local broadcast receiver as shown by the same guide as above.
That's how my manifest looks like:
<?xml version="1.0" encoding="utf-8"?>

</application>
Since I'm using 3.2 sdk version, the app should automatically subscribe the user to push-notifications, but this not happen. Actually the listener code prints nothing:
//This is in AppraiaApplication extends Application
#Override
public void onCreate() {
super.onCreate();
QBSettings.getInstance().init(getApplicationContext(), APP_ID, AUTH_KEY, AUTH_SECRET);
QBSettings.getInstance().setAccountKey(ACCOUNT_KEY);
QBPushManager.getInstance().addListener(new QBPushManager.QBSubscribeListener() {
#Override
public void onSubscriptionCreated() {
System.out.println("onSubscriptionCreated");
}
#Override
public void onSubscriptionError(final Exception e, int resultCode) {
System.out.println("onSubscriptionError" + e);
if (resultCode >= 0) {
System.out.println("Google play service exception");
}
System.out.println("onSubscriptionError " + e.getMessage());
}
});
QBSettings.getInstance().setEnablePushNotification(true);
LocalBroadcastManager.getInstance(this).registerReceiver(pushBroadcastReceiver,
new IntentFilter("new-push-event"));
System.out.println("Application creation ended");
}
What am I doing wrong?

Looks like you don't make signIn with user, and subscription is not performed. Also have a look in logs, there is can be info something like D/QBASDK: SubscribeService: SubscribeService created. So, you can figure out whether the subscription is executed at all.

AdMob still not working

I got a problem regarding Google AdMob:
I try to display a Interstitial, for this I have added the AdActivity, permissions and meta-tags to manifest.

In MainActivity:
mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId("xxx/xxx");
AdRequest adRequest = new AdRequest.Builder().build();
mInterstitialAd.loadAd(adRequest);
if (mInterstitialAd != null && mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
}
Logcat:

Besides there is also a compilation error:
Conversion of dalvik format failed with error code 1
I tried about 20 answers, still not working.
I also dont know whether the problem is the unit id, I can change
mInterstitialAd.setAdUnitId("xxx/xxx");
to:
mInterstitialAd.setAdUnitId("xxx");
and I got the same errors.
I use the following external libraries:
android support v4&v7, picasso, ftpclient(commons, httpmime),FAB
Does somebody have a advice?
Greetings

Solution found!
Seems like some features in CyanogenMod blocks AdMob.
Flashed a new version WITHOUT Adaware and blocking Tools.
WORKING NOW :D

I haveSecurityException: Permission Denial error

I am getting the following error:
ActivityManager: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.optionpricing/.optionListNew } from null (pid=1160, uid=2000) requires null
I am new to programming in Android and I could not make sense of the other postings related to my problem. I wonder if there is an issue with the optionListNew class? Can someone lend a hand so I can move on to completing my app. Also, the app runs in my virtual device, and I only get this error when I try to test it on my actual phone.
Any ideas are appreciated. Below is the manifest file.
<?xml version="1.0" encoding="UTF-8"?>
<manifest android:versionCode="1" android:versionName="1.0"
package="com.optionpricing" xmlns:android="http://schemas.android.com/apk/res/android">

<activity android:name=".barrierSingleUpInActivity"/>
<activity android:name=".testActivity"/>
<activity android:name=".barrierlistview"/>
<activity android:name=".barrierSingleDownInActivity"/>
</application>
</manifest>

You added "optionListNew" activity twice in the manifest file.. remove below activity by deleting this line
<activity android:name=".optionListNew"/>
Your Manifest.xml code will become
<?xml version="1.0" encoding="UTF-8"?>
<manifest android:versionCode="1" android:versionName="1.0"
package="com.optionpricing" xmlns:android="http://schemas.android.com/apk/res/android">
<uses-sdk android:minSdkVersion="8"/>
<application android:icon="#drawable/icon"
android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".optionListNew">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name=".OptionPricing"/>
<activity android:name=".futureOptionActivity"/>
<activity android:name=".currencyOptionActivity"/>
<activity android:name=".gapOptionActivity"/>
<activity android:name=".gapOptionList01"/>
<activity android:name=".barrierSingleUpInActivity"/>
<activity android:name=".testActivity"/>
<activity android:name=".barrierlistview"/>
<activity android:name=".barrierSingleDownInActivity"/>
</application>
</manifest>

optionListNew is present twice in the manifest. Remove the second.

Google Maps NoClassDefFoundError

I'm working on an android project in which one of the activities includes a Maps view. I'm only after doing the code for displaying a simple Google Map but I bumped into this NoClassDefFoundError. I have checked some similar questions and tried the suggested solutions but still won't work. I have activated the Internet permision in the manifest file and the user library for the application. Does anyone have any suggestions on what might be the problem? Here's the activity code:
package com.mad.mylit;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
public class LocationsActivity extends MapActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.location);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
And here's my manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mad.mylit"
android:versionCode="1"
android:versionName="1.0" android:installLocation="auto">

All of the activities are in the same package.

Try to get new maps API key with your personal keystore.

Have you recently updated your ADT plugin?
Here and here are some talks about same prblem..

changing launching activity

i want to change my launching activity.for the moment my manifest is this:
<application android:icon="#drawable/iconbj" android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".Main" android:label="#string/app_name" android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:label="DemoPlayActivity" android:name="DemoPlayActivity" android:screenOrientation="landscape"></activity>
</application>
now I have created another activity which is a splash screen and i want to launch this instead of Main so I tried this way:
<application android:icon="#drawable/iconbj" android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".Splash" android:label="#string/app_name"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="Main" android:label="Main"
android:screenOrientation="landscape">
</activity>
<activity android:label="DemoPlayActivity" android:name="DemoPlayActivity"
android:screenOrientation="landscape"></activity>
</application>
but i get thisproblem with permission:
[2011-03-31 16:32:44 - BlackJackNuovo]
ActivityManager:
java.lang.SecurityException:
Permission Denial: starting Intent {
act=android.intent.action.MAIN
cat=[android.intent.category.LAUNCHER]
flg=0x10000000
cmp=com.phinet.android.blackjack/.Main
} from null (pid=-1, uid=-1) requires
null.
please help me :)
Update
NO WAY. I did this way:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.phinet.android.blackjack" android:versionCode="1"
android:versionName="1.0">

<uses-permission android:name="android.permission.VIBRATE" />
<application android:icon="#drawable/iconbj" android:label="#string/app_name"
android:debuggable="true">
<activity android:name="com.phinet.android.blackjack.Splash" android:label="Splash"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.phinet.android.blackjack.Main" android:label="Main"
android:screenOrientation="landscape">
</activity>
<activity android:label="com.phinet.android.blackjack.DemoPlayActivity" android:name="DemoPlayActivity"
android:screenOrientation="landscape"></activity>
</application>
</manifest>
but it seems to lunch always the Main activity,this is the concole log:
[2011-04-01 10:57:10 - BlackJackNuovo] Uploading BlackJackNuovo.apk onto device '9000d365e767'

WHY?

<activity android:name="Main" android:label="Main"
android:screenOrientation="landscape">
</activity>
<activity android:label="DemoPlayActivity" android:name="DemoPlayActivity"
android:screenOrientation="landscape"></activity>
Should still have the leading .
<activity android:name=".Main" android:label="Main" android:screenOrientation="landscape">
</activity>
<activity android:label=".DemoPlayActivity" android:name="DemoPlayActivity"android:screenOrientation="landscape">
</activity>
This is stating it has a relative path to your Classes. You could make absolute references if you wished, i.e. "com.your.app.Main"
