No Activity found to handle Intent - Error

Hey guys I have already made few apps and doing exactly the same this time though I am getting errors. Please check my logcat below
Code:
05-04 07:35:41.888: E/AndroidRuntime(1066): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.droidacid.count.COUNT }
This is my java code of main class
Code:
package com.droidacid.count;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class mainMenu extends Activity {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_menu);
Button count = (Button) findViewById(R.id.count);
try{
bapticalc.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent("com.droidacid.count.COUNT"));
}
});
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
this is my count class code
Code:
package com.droidacid.count;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class system extends Activity{
Button system;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.apticalc);
system = (Button) findViewById(R.id.system);
system.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent("com.droidacid.count.SYSTEM"));
}
});
}
}
And atlast this is my android manifest code
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.droidacid.count"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".mainMenu"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".count"
android:label="@string/app_name"
>
<intent-filter>
<action android:name="com.example.sweet_memories.COUNT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
I am really sorry for such a long question guys but really wanted to state everything happening with me...Also I would really appreciate if someone would help me on how to check logcat properly for errors?

So, from your mainMenu you are sending an intent to start the "count", is that the activity that you have named system?
Code:
public class system extends Activity
and in the "system" activity you are trying to start itself? And you also have a button named system?
I think you should rename the class "system" to "count", eclipse will offer you to change the compilation unit to count automatically. And I shouldn't name a button system, maybe mBtnSystem or something like that.

2.3.3 to 4.2.2 Http Get - Help me conquer learning curve

Hey all!
New to Android but not developing. App runs great with emulator running Android 2.3.3. When I install the app to my phone (Samsung Galaxy 4S Active) runnnig Android 4.2.2, the Http Get execute command on the client does not seem to happen. I get no data back reported to my TextView.

[Tutorial]Android CollapsingToolBarLayout with ViewPager

Final Output would look like this(gif) : http://imgur.com/mVcQv1l
(Or have a look in the attachments)
A Simple Tutorial on using CollapsingToolbarLayout with ViewPager.I'll try to keep it in brief.
So,first of all add the following to your dependencies in build.gradle(Module: app)
compile 'com.android.support:design:23.4.0'
Click to expand...
Click to collapse
Open your activity_main.xml and write this:-
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/maincontent"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
>
<android.support.design.widget.AppBarLayout
android:id="@+id/htab_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/htab_collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginStart="48dp"
app:expandedTitleMarginEnd="64dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
>
<ImageView
android:id="@+id/header"
android:layout_width="match_parent"
android:layout_height="250dp"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.7"
/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="top"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
/>
</android.support.design.widget.CollapsingToolbarLayout>
/></android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
/>
</android.support.design.widget.CoordinatorLayout>
Click to expand...
Click to collapse
Note:-
●You can change the color of scrim by changing "app:contentScrim" in the above xml or dynamically in the MainActivity.java by,
Code:
collapsingToolbar.setContentScrimColor(getResources().getColor(R.color.COLORYOUWANT));
●To change the position of CollapsingToolbarLayout,you can change the following attributes:
Code:
app:expandedTitleMarginStart="SIZEYOUWANTdp"
app:expandedTitleMarginEnd="SIZEYOUWANTdp"
Now create new xml files,that'll be the pages of your ViewPager
For Example,create page1.xml and page2.xml
Keep the contents of the pages in NestedScrollView otherwise CollapsingToolbarLayout will not be collapsing when using ViewPager (You can use RecyclerView also.)
page1.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android: orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:fillViewport="true"
android:fitsSystemWindows="true"
android:layout_gravity="fill_vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="PAGE 1"
android:textAlignment="center"
android:textSize="40sp"
android:textStyle="bold"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginTop="210dp" />
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
</RelativeLayout>
Click to expand...
Click to collapse
*Assuming you know the basics about ViewPager*
Now create Adapter and Model for your ViewPager.
Create a new class,named customadapter.
customadapter.java
Code:
import android.content.Context;
import android.os.Parcelable;
import android.support.v4.view.PagerAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
/**
* Created by theprakhar on 04-06-2017.
*/
public class customadaptar extends PagerAdapter
{
private Context mContext;
public customadaptar(Context context) {
mContext = context;
}
@Override
public Object instantiateItem(ViewGroup collection, int position) {
custommodel modelObject = custommodel.values()[position];
LayoutInflater inflater = LayoutInflater.from(mContext);
ViewGroup layout = (ViewGroup) inflater.inflate(modelObject.getLayoutResId(), collection, false);
collection.addView(layout);
return layout;
}
@Override
public void destroyItem(ViewGroup collection, int position, Object view) {
collection.removeView((View) view);
}
@Override
public int getCount() {
return custommodel.values().length;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public CharSequence getPageTitle(int position) {
custommodel customPagerEnum = custommodel.values()[position];
return mContext.getString(customPagerEnum.getTitleResId());}
public Parcelable saveState() {
// Do Nothing
return null;
}
}
Now create an enum,name it custommodel.That'll be the model for the viewpager where we'll link the layouts of the different pages.
custommodel.java
Code:
public enum custommodel {
PAGEONE(R.string.pageone, R.layout.page1),
PAGETWO(R.string.pagetwo, R.layout.page2);
private int mTitleResId;
private int mLayoutResId;
custommodel(int titleResId, int layoutResId) {
mTitleResId = titleResId;
mLayoutResId = layoutResId;
}
public int getTitleResId() {
return mTitleResId;
}
public int getLayoutResId() {
return mLayoutResId;
}
}
Now place the header image in the drawable folder,and now we'll dynamically set image in ImageView in MainActivity (Though you can directly do in that xml)
*If you do not want an image in your Collapsing Toolbar,simply remove the ImageView inside CollapsingToolbarLayout.*
**TIP:-Try to keep the size of the image below 100KB for smooth scroll**
Now head on to MainActivity.java and set up ViewPager and CollapsingToolbar.
MainActivity.java
Code:
import android.support.design.widget.CollapsingToolbarLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
private ViewPager viewPager;
CollapsingToolbarLayout collapsingToolbar;
ImageView image;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager=(ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(new customadaptar(this));
image = (ImageView)findViewById(R.id.header);
image.setImageResource(R.drawable.header);
collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.htab_collapse_toolbar);
collapsingToolbar.setTitle("Collapsing Toolbar Example");
}
}
Go run and test your code.You did it,bruh.

if (messageEvent.getPath().equals(MESSAGE_PATH)) {
Log.d(TAG, "good message");
} else {

my MainActivity with this onCreate:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
startService(new Intent(MainActivity.this, ListenerService.class));
}
When I start the App on my phone I got in the Logcat:
Code:

When I send with the wearapp some data to my phone, my ListenerService didn't fire the onMessageReceived method..
Here is my AndroidManifest from the wearapp:
Code:
<?xml version="1.0" encoding="utf-8"?>

When I the message got send, i got this in the logcat from the wearapp:
Code:
sh.evolutio.carwear D/MainActivity: isConnected: true
sh.evolutio.carwear D/MainActivity: connected to: 778d0d53
sh.evolutio.carwear V/MainActivity: Message: { forward } sent to: HUAWEI Mate 10 Pro
sh.evolutio.carwear D/MainActivity: onSuccess: 17282
so the message was sent to my Mate 10 Pro. But why my Mate 10 Pro App can't receive the Message?
