I am trying to get a record from a `posts` database table using its id. I&#39;ve been banging my head on the find() method for quite sometime now, confused as to why it wasn&#39;t working. Here is my query that looks correct to me but didn&#39;t work:

    $post = Post::find($id);
    $post-&gt;delete();

Reluctantly i did this:

    $post = Post::where(&#39;id&#39;, $id);
    $post-&gt;delete();

and surprisingly enough, it worked but I have no idea how. 

I also know that unlike `find()`,  `where()` is a query builder and so I could also use it like this:
`Post::where(&#39;id&#39;, $id)-&gt;first()`

Any ideas about the difference in the way the methods work?

Since today, Android Studio can&#39;t find the AppCompat themes in styles.xml, but for example AppCompatActivity in code does get recognized. My Android Studio version is 2.2.2, Build #AI-145.3360264

I already tried upgrading to the latest build tools, compile sdk (25) version etc. but it didn&#39;t fix the problem.

At the moment I have installed the following (from sdk manager):

 - android api: 19 and 23
 - sdk platform tools: 25.0.1
 - sdk tools: 25.2.3
 - build-tools: 23.0.2 and 25.0.1
 - support repository: 40
 - google repository: 39

and a few others, that shouldn&#39;t be necessary to list here.

build.gradle of app:

    apply plugin: &#39;com.android.application&#39;
    
    android {
        compileSdkVersion 23
        buildToolsVersion &#39;25.0.1&#39;
        defaultConfig {
            applicationId &quot;xxx.xxxxxxxx.xxxxxxxxx&quot; //not the real applicationId
            minSdkVersion 14
            targetSdkVersion 19
            versionCode 1
            versionName &quot;1.0&quot;
            testInstrumentationRunner &quot;android.support.test.runner.AndroidJUnitRunner&quot;
        }
        buildTypes {
            release {
                minifyEnabled true
                shrinkResources true
                proguardFiles getDefaultProguardFile(&#39;proguard-android.txt&#39;), &#39;proguard-rules.pro&#39;
            }
            debug {
    
            }
        }
    }
    
    dependencies {
        compile fileTree(include: [&#39;*.jar&#39;], dir: &#39;libs&#39;)
        compile files(&#39;libs/RootTools.jar&#39;)

Cannot resolve symbol &#39;Theme&#39; in styles.xml (Android Studio)

I&#39;m trying to verify that my source and target paths are properly setup when I execute a deploy command.

See the example below:&lt;br/&gt;
(copied from: http://eppz.eu/blog/unity-android-plugin-tutorial-2/)

```groovy
android.libraryVariants.all { variant -&gt;
	// Task names.
	String variantName = &quot;${variant.name.capitalize()}&quot;; // Like &#39;Debug&#39;
	String deployTaskGroup = &quot;plugin&quot;;
	String deployTaskName = &quot;deploy${variantName}PluginArchive&quot;; // Like &#39;deployDebugPluginArchive&#39;
	String dependencyTaskName = &quot;assemble${variantName}&quot;; // Like &#39;assembleDebug&#39;
	// Source.
	String sourceAARFolder = &quot;${buildDir.getPath()}/outputs/aar/&quot;;
	String sourceAARName = &quot;${project.name}-${variant.name}.aar&quot;;
	// Target.
	String targetAssetFolder = &quot;Assets/Plugins/My Plugin&quot;;
	String targetAARFolder = &quot;${rootDir.getPath()}/../../${targetAssetFolder}&quot;; // Navigate into &#39;Assets&#39;
	String targetAARName = &quot;My Plugin Android.aar&quot;; // The form you ship your plugin

    String targetProjDir = System.env.UNITY_PROJECT; // &lt;-- Need to confirm this line!
    //Log.i(targetProjDir); //??????????? something like this?

	// Create task.
	task(deployTaskName, dependsOn: dependencyTaskName, type: Copy) {
		from(sourceAARFolder)
		into(targetAARFolder)
		include(sourceAARName)
		rename(sourceAARName, targetAARName)
	}.group = deployTaskGroup;
}
```

Is there any way to display the above `targetProjDir` string variable to some sort of console, or the Event Log in Android Studio (assuming that is it&#39;s console&#39;s name)?


In Gradle, how to print out a message in the console / Event Log?

I need to update my code style. Reformatting the whole project files one by one takes too much effort with the [shortcuts][1] I know.
&gt; &lt;kbd&gt;Opt&lt;/kbd&gt; + &lt;kbd&gt;Command&lt;/kbd&gt; + &lt;kbd&gt;L&lt;/kbd&gt;

**My Question?**
================

Is there any other way to do it for the whole project?

Reformat Whole Project Files in Android Studio

Everyone!

I got so confused by android studio.
when I plug in my phone to debug apps, logcat can detect my phone, but I can not choose process. It said &quot;no debuggable processes&quot;,not common &quot;no debuggable applications&quot;.

My phone is samsung s5 (android 6.0),rooted.

Any ideas?

Thanks!

VScode notifies you when you open a config of an extension:

&gt; remember to Restart VScode

[![enter image description here][1]][1]

But it says nothing about how. They use capital letter for the `restart` word, so normally it should mean something if you emphasize an appellation. Is there some hidden restart button or a key shortcut?  
How do I restart the IDE?

In Visual Studio Professional, we have a shortcut key, &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;M&lt;/kbd&gt; &lt;kbd&gt;Ctrl&lt;/kbd&gt;  + &lt;kbd&gt;O&lt;/kbd&gt; to collapse all methods and properties in a class. How can I do a similar thing in Visual Studio Code?

I know there are shortcut keys like &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;[&lt;/kbd&gt;, but this does not meet the needs.

Is it possible to get the Visual Studio Professional-like behaviour in Visual Studio Code?

I have 4 lines like this in vscode:  

&gt; 1 line;   
&gt; 2 line;  
&gt; 3 line;

Does vscode have a shortcut that can quickly compact 4 lines to 1 line like this:

If I quick open a file using the quick open menu, is there a **keyboard shortcut** that will take the opened file outside of preview mode so that when I open a new file it won&#39;t replace the currently open one?

(I&#39;m looking for a keyboard shortcut as opposed to double-clicking the filename or tab in order to keep my workflow keyboard oriented)
