The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to [this Google blogpost][1]:

&gt; It’s best practice to place your app icons in **mipmap-** folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the **mipmap-** folders ensure you are using the following reference:

    android:icon=&quot;@mipmap/ic_launcher&quot;

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

I have a condition in a silverlight application that compares 2 strings, for some reason when I use `==` it returns **false** while `.Equals()` returns **true**.

Here is the code:

    if (((ListBoxItem)lstBaseMenu.SelectedItem).Content.Equals(&quot;Energy Attack&quot;))
    {
        // Execute code
    }

    if (((ListBoxItem)lstBaseMenu.SelectedItem).Content == &quot;Energy Attack&quot;)
    {
        // Execute code
    }

Any reason as to why this is happening?

Does `time.time()` in the Python time module return the system&#39;s time or the time in UTC?

Does Python&#39;s time.time() return the local or UTC timestamp?

I&#39;m working with Android Studio 1.1 Preview 1. I noticed that when I create a new project I&#39;m getting the following hierarchy:

![Enter image description here][1]

Mipmap folders for different DPIs, no more different DPIs drawable folders.

Should I put all my resources in the mipmap folders, or just the app icon?

I have to switch between two layouts frequently. The error is happening in the layout posted below.

When my layout is called the first time, there doesn&#39;t occur any error and everything&#39;s fine. When I then call a different layout (a blank one) and afterwards call my layout a second time, it throws the following error:


    &gt; FATAL EXCEPTION: main
    &gt;     java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child&#39;s parent first.



My layout-code looks like this:

        tv = new TextView(getApplicationContext()); // are initialized somewhere else
        et = new EditText(getApplicationContext()); // in the code


    private void ConsoleWindow(){
            runOnUiThread(new Runnable(){
    
         @Override
         public void run(){
    
            // MY LAYOUT:
            setContentView(R.layout.activity_console);
            // LINEAR LAYOUT
            LinearLayout layout=new LinearLayout(getApplicationContext());
            layout.setOrientation(LinearLayout.VERTICAL);
            setContentView(layout);
    
            // TEXTVIEW
            layout.addView(tv); //  &lt;==========  ERROR IN THIS LINE DURING 2ND RUN
            // EDITTEXT
            et.setHint(&quot;Enter Command&quot;);
            layout.addView(et);
            }
        }
    }

I know this question has been asked before, but it didn&#39;t help in my case.

I&#39;m looking for a way to display the hamburger icon whitout using the Drawer/DrawerToggle and use the default icon included in Android
![enter image description here][1]

By setting `getSupportActionBar().setDisplayHomeAsUpEnabled(true);` it display the back arrow but not the hambuerger. Other post on Stackoverflow (like [this][2] or [this][3]) use the DrawerLayout or a custom drawable. I cannot find the vector or png for the hamburger icon on the Android source. 

**Do you know how can I find the original hamburger icon in android/support library?** (or how to displayed it)

*Note:  Vector and png can be found on google.com/design website :* http://www.google.com/design/spec/resources/sticker-sheets-icons.html#

I am using Android studio with Gradle builds. I test my app on a device and let Android Studio and Gradle build the app and install it on the device. How can I tell Gradle or Android Studio to uninstall the app from the device before installing a new version?

How to automatically uninstall android app from device before installing a new version

I am in the process of moving my current projects huge application into Android Studio and Gradle. I am currently stuck on the following issue:

    Error:(87, 9) Execution failed for task &#39;:App:processDebugManifest&#39;.
    &gt; Manifest merger failed : Attribute application@label value=(@string/app_label) from AndroidManifest.xml:87:9
    	is also present at ANDROID_APPLICATION:Library:unspecified:9:18 value=(@string/app_name)
    	Suggestion: add &#39;tools:replace=&quot;android:label&quot;&#39; to &lt;application&gt; element at AndroidManifest.xml:82:5 to override

I have tried adding the following attributes to the main `AndroidManifest.xml` file:

    tools:replace=&quot;android:label, *App Name*&quot;
    tools:replace=&quot;android:label, @string/app_label&quot;
    tools:replace=&quot;android:label&quot;

None of these attribute definitions works. What am I doing wrong?

In Android Studio, I can&#39;t figure out where to put images to be used inside the app. The drawable folder isn&#39;t broken down into drawable-hdpi, drawable-ldpi, etc. I saw another question asking this and the answer was to switch to Project view instead of Android view but drawable is only one folder there too. There is mipmap-hdpi, mipmap-ldpi, etc, but people are saying that&#39;s only for app icons. I&#39;m confused.

Android Studio drawable folders

With new android API 22 `getResources().getDrawable()` is now deprecated.
Now the best approach is to use only `getDrawable()`.

What changed?

I need to add an image to the `res/drawable` folder...

When I choose `new &gt; Image Asset`, it comes out a dialog to choose `Asset Type`...

How can I add an image to `res/drawable` folder?




How to add an image to the &quot;drawable&quot; folder in Android Studio?

Hi [as per android documentation][1] the drawable folder needs to have multiple sub-directories for images of different dpis. However in Android Studio creating any sub directory in the drawable folder causes it to fail to detect any images at all. On the other hand if an image is placed directly in the drawable folder it gets detected and becomes available for use view R.drawable.ImageName. In this case how do we use different dpi images for the same ImageName?

Android Studio: Drawable Folder: How to put Images for Multiple dpi?

In my application, I have to set a large icon for a notification.
LargeIcon must be a Bitmap, and my drawables are vector images (the new feature in Android, see [this link][1])
The problem is when I try to decode a resource that is a vector image, I get a null returned.

Here is the sample of code :

    if (BitmapFactory.decodeResource(arg0.getResources(), R.drawable.vector_menu_objectifs) == null)
			Log.d(&quot;ISNULL&quot;, &quot;NULL&quot;);
		else
			Log.d(&quot;ISNULL&quot;, &quot;NOT NULL&quot;);
In this sample, when I replace R.drawable.vector_menu_objectifs with a &quot;normal&quot; image, a png for exemple, the result is not null (I get the correct bitmap)
Is there something I&#39;m missing?
