related to this [answer][1] By default, all 32-bit applications run without a glitch on 64-bit processors, but might run slower than applications tuned to run on 64-bit processors.

and according with this [article][2]

&gt; With Google’s recent release of its x86 64-bit Android 5.0 emulator
&gt; image, developers can create 64-bit apps for Intel Atom
&gt; processor-based devices.

**Android 32-bit vs 64-bit**

&gt; Many 64-bit platforms today, including Solaris, AIX*, HP-UX*, Linux*,
&gt; OS X*, BSD, and IBM z/OS*, use an LP64 model. Since Android is based
&gt; on the Linux kernel, Android 64-bit platforms also use the LP64 model.
&gt; 
&gt; 
&gt; Intel 64-bit CPUs have a 32-bit compatibility mode. While 32-bit
&gt; applications will run on 64-bit processors, **compiling with a 64-bit
&gt; optimizing compiler allows them to take advantage of the architectural
&gt; benefits of a 64-bit environment**.

Android with 64-bit technologies for Intel Atom processor-based platforms can help developers to **optimize their applications** now. Building Android applications for 64-bit is just as easy as building traditional 32-bit Android applications. You can now use the official Android 64-bit emulator to run and debug 64-bit apps.

Maybe this articles can help you to understand the difference between this system images.


**Update**

Google now encourage to use x86 emulator like you can see in this image

[![enter image description here][3]][3]

The difference is that when using x86 images, it now uses fast, hardware-accelerated virtualization under the right conditions ([HAXM][4]) so it doesn&#39;t feel like there&#39;s a fat middle layer anymore.

I have some code in Java that I want to exclude from code coverage. How would I do this? I want to be able to add an annotation. Is there a way to configure or extend jacoco (as used in gradle) to use this?

Example:

    public class Something
    {
        @ExcludeFromCodeCoverage
        public void someMethod() {}
    }

How would I add an annotation to exclude a method from a jacoco code coverage report?

I&#39;m totally new to Android programming. I have Android Studio 3.0.1 running on Kubuntu Xenial 64-bit on a desktop with a Haswell processor.

I am configuring virtual devices. I am thinking of doing that corresponding to the physical Android devices I own. However, I notice that x86 images are placed in the &quot;Recommended&quot; pane:

[![enter image description here][1]][1]

compared to the x86_64 images of identical API version and target:

[![enter image description here][2]][2]

\#4 of https://developer.android.com/studio/run/managing-avds.html#createavd seems to indicate that x86 images are recommended because they &quot;run the fastest in the emulator.&quot;

A few of my old devices are x86 but the newer ones are x86_64. Should I choose x86_64 accordingly though it is not in the &quot;Recommended&quot; pane?

Does this make a difference when I am going to distribute APKs on Google Play Store in the future?

I have View and one CircleShape , which should show toast in this View. And I use it in main Activity.
This is my interface 

    interface OnClickListenerInterface {
      fun onClick()
    }


It is CircleShape( it is View in my xml) and listener in my View. I want to implement OnClick in my Activity. 

     var listener: OnClickListenerInterface? = null
    
     mCircleShape.setOnClickListener(View.OnClickListener {
          if (listener == null) return@OnClickListener
          listener!!.onClick()
        })

I know , that in Kotlin getters and setters generic automatics, but how I can set listener if it private. It is code from my Activity, but It doesn&#39;t work

  

    CircleShape.listener  = object :OnClickListenerInterface{
          override fun onClick() {
            ToastUtils.showSuccessMessage(getContext(),&quot;pressed&quot;)
          }
        }

The documentation does not have any examples on how to add a subcollection to a document. I know how to add document to a collection and how to add data to a document, but how do I add a collection (subcollection) to a document?

Shouldn&#39;t there be some method like this:

    dbRef.document(&quot;example&quot;).addCollection(&quot;subCollection&quot;)

How to add subcollection to a document in Firebase Cloud Firestore

I have a separate class in which I handle data fetching (specifically Firebase) and I usually return LiveData objects from it and update them asynchronously. Now I want to have the returned data stored in a ViewModel, but the problem is that in order to get said value, I need to observe the LiveData object returned from my data fetching class. The observe method required a LifecycleOwner object as the first parameter, but I obviously don&#39;t have that inside of my ViewModel and I know I am not supposed to keep a reference to the Activity/Fragment inside of the ViewModel. What should I do?

Observing LiveData from ViewModel

After upgrading my phone to 8.1 Developer Preview my background service no longer starts up properly.

In my long-running service I&#39;ve implemented a `startForeground` method to start the ongoing notification which is called in on create.

    @TargetApi(Build.VERSION_CODES.O)
    private fun startForeground() {
        // Safe call, handled by compat lib.
        val notificationBuilder = NotificationCompat.Builder(this, DEFAULT_CHANNEL_ID)

        val notification = notificationBuilder.setOngoing(true)
                .setSmallIcon(R.drawable.ic_launcher_foreground)
                .build()
        startForeground(101, notification)
    }

`invalid channel for service notification`, apparently my old channel the `DEFAULT_CHANNEL_ID` is no longer appropriate for API 27 I assume. What would be the proper channel? I&#39;ve tried to look through the documentation

Unable to resolve dependency for &#39;:app@debug/compileClasspath&#39;: Could not resolve

I&#39;m using **Android Studio 3.2 Beta5** to migrate my project to **AndroidX**. When I rebuild my app I got these errors:

&gt; ERROR: [TAG] Failed to resolve variable &#39;${animal.sniffer.version}&#39;
&gt;
&gt; ERROR: [TAG] Failed to resolve variable &#39;${junit.version}&#39;

Full clean &amp; rebuild did not work! Anyone know how to fix this?
