&gt; Error:Jack is required to support java 8 language features. Either
&gt; enable Jack or remove sourceCompatibility JavaVersion.VERSION_1_8.

The error say that you have to **enable Jack**.

To enable support for Java 8 in your Android project, you need to configure your `build.gradle` file like that

    android {
      ...


      compileSdkVersion 23
      buildToolsVersion &quot;24rc2&quot;
      defaultConfig {
      ...
        jackOptions {
          enabled true
        }
      }
     
      compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
      }
    }

I am trying to install flake8 package using pip3 and it seems that it refuses to install because is already installed in one local location. 

How can I force it to install globally (system level)?

    pip3 install flake8
    Requirement already satisfied (use --upgrade to upgrade): flake8 in ./.local/lib/python3.4/site-packages

Please note that I would prefer a generic solution (that should work on Debian, OS X maybe even Windows), one that should be used on any platform so I don&#39;t want to specify the destination myself.

For some weird reason it behaves like I already specified `--user` which in my case I didn&#39;t.

The only way I was able to install a package globally was to first remove it and install it again after this. Somehow it seems that pip (8.1.1) refuses to install a package globally if it exists locally.

Disclaimer: No virtual environments were used or harmed during the experiments.

How do I install a pip package globally instead of locally?

I have a collection of photos, and I&#39;m using a `RecyclerView` to display them. I want to have the first element in my `RecyclerView` span 2 columns AND 2 rows:
[![enter image description here][1]][1]

I know I can span 2 columns with `setSpanSizeLookup`:

    GridLayoutManager gridLayoutManager = new GridLayoutManager(this, 3);
    gridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
        @Override
        public int getSpanSize(int position) {
            if (position == 0) {
                return 2;
            } else {
                return 1;
            }
        }
    });

**but how can I also make the first item span 2 rows as well?**

I have tried setting the first item&#39;s height to be different by inflating a different layout with double the height of the others, but that resulted in every item on the same row as the first item also being stretched to that height:

    @Override
    public ProfilePicViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView;
        if (viewType == TYPE_MAIN_PHOTO) {
            itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view_main_profile_photo, parent, false);
        } else {
            itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view_profile_photo, parent, false);
        }
        return new ProfilePicViewHolder(itemView);
    }

I see that the Android Plugin for Gradle has a `minifyEnabled` property as well as a `useProguard` property, as follows:

    android {
        buildTypes {
            debug {
                minifyEnabled true
                useProguard false
            }
            release {
                minifyEnabled true
                useProguard true
            }
        }
    }

What&#39;s the difference between these two properties? Or, rather, what&#39;s the meaning of each?

I guess the problem probably can be in my android device(it is chinese Doogee X5). It does not have a given USB Vendor ID in developer docs so I decided to follow instructions with random vendor ID from HTC. 

I&#39;m sure there is a way to run application on any android device, but yet I didn&#39;t find an answer on how to do that.

How to add a Hint in spinner in XML

I just switched to Android Studio 2.1 and this error showed up when trying to compile an app the was previously working:

&gt;     Error:Error converting bytecode to dex:
&gt;     Cause: Dex cannot parse version 52 byte code.
&gt;     This is caused by library dependencies that have been compiled using Java 8 or above.
&gt;     If you are using the &#39;java&#39; gradle plugin in a library submodule add 
&gt;     targetCompatibility = &#39;1.7&#39;
&gt;     sourceCompatibility = &#39;1.7&#39;
&gt;     to that submodule&#39;s build.gradle file.

I had already updated the main project&#39;s gradle.build file to force Java 1.7 code generation:

    buildscript {
        repositories {
            jcenter()
        }
        dependencies {
            classpath &#39;com.android.tools.build:gradle:2.1.0&#39;
            apply plugin: &#39;java&#39;
            sourceCompatibility = 1.7
            targetCompatibility = 1.7
        }
    }
I had also updated the module gradle.build as follows to set the java version:

    android {
    compileSdkVersion 19
    buildToolsVersion &quot;23.0.2&quot;

    defaultConfig {
        applicationId &quot;com.abc.def&quot;
        minSdkVersion 19
        targetSdkVersion 19
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(&#39;proguard-android.txt&#39;), &#39;proguard-rules.txt&#39;
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    }


The submodule being built with Maven.  In the pom.xml file I have also tried to force 1.7 code generation.  
I understand that I am using an assembly artifact, which incorporates subordinate modules, but i have not changed any of the subordinate modules and the resulting .jar file for the module ran fine last time I compiled.

    	&lt;build&gt;
		&lt;plugins&gt;
			&lt;plugin&gt;
				&lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
				&lt;artifactId&gt;maven-assembly-plugin&lt;/artifactId&gt; &lt;!-- maven-compiler-plugin --&gt;
				&lt;version&gt;2.6&lt;/version&gt;
				&lt;configuration&gt;
					&lt;source&gt;1.7&lt;/source&gt;
					&lt;target&gt;1.7&lt;/target&gt; 
					&lt;descriptorRefs&gt;
						&lt;descriptorRef&gt;jar-with-dependencies&lt;/descriptorRef&gt;
					&lt;/descriptorRefs&gt;
				&lt;/configuration&gt;
				&lt;executions&gt;
					&lt;execution&gt;
						&lt;id&gt;make-assembly&lt;/id&gt; &lt;!-- this is used for inheritance merges --&gt;
						&lt;phase&gt;package&lt;/phase&gt; &lt;!-- bind to the packaging phase --&gt;
						&lt;goals&gt;
							&lt;goal&gt;single&lt;/goal&gt;
						&lt;/goals&gt;
					&lt;/execution&gt;
				&lt;/executions&gt;
			&lt;/plugin&gt;
		&lt;/plugins&gt;
	&lt;/build&gt;

My question: 
1) Is this an Android Studio 2.1 problem?  Have others seen it?
2) Assuming this is my error and since the error message gives no help in finding the bad module, are there any recommendations on finding the V52 code?  I can&#39;t just omit the libraries without breaking large amount of code.  Can one inspect a .jar file to find the code revision?
Thanks in advance.

Android: Dex cannot parse version 52 byte code

I have used the lint(**Analyze-&gt;Inspect** Code...) and find out unused methods and resources. All the unused resources removed by **Refractor-&gt;Remove unused Resources** but not found any option like this to remove java classes and methods. 
Is there any feature in the android studio or any Plugin which can remove all the java classes, the methods which are not used in code to save manual refracting?

Android Studio - Failed to apply plugin [id &#39;com.android.application&#39;]

I&#39;ve been trying to import a project to Android Studio and this is where I am stuck, there is a similar question on [Stack Overflow][1] but it did not provide a solution to my particular error. 

This is my error log:

    C:\&lt;some location&gt;\build.gradle

    Error:(24, 1) A problem occurred evaluating root project &#39;&lt;project name&gt;&#39;.

Could not find method android() for arguments

Since I updated to Android SDK Tools 25.1.6 and Android Support Repository 32.0.0 (this morning), I got the following error, I didn&#39;t change anything in my code and it is still working on my colleague computer (Android SDK Tools 25.1.1 + Android Support Repository 30.0.0). 

    java.lang.IncompatibleClassChangeError: The method 
         &#39;java.io.File android.support.v4.content.ContextCompat.getNoBackupFilesDir(android.content.Context)&#39; 
         was expected to be of type virtual but instead was found to be of type direct 
         (declaration of &#39;java.lang.reflect.ArtMethod&#39; appears in /system/framework/core-libart.jar)

         at android.os.Handler.dispatchMessage(Handler.java:102)
         at android.os.Looper.loop(Looper.java:145)
         at android.os.HandlerThread.run(HandlerThread.java:61)


Here is a the piece of code that crash:

    InstanceID instanceID = InstanceID.getInstance(this); // &lt;-- crash here
    String instanceIDToken = instanceID.getToken(getString(R.string.google_app_id),
    GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

It is when I try to get a token from Google Cloud Messaging.

I&#39;m importing GCM in Gradle with splited play-services :

     compile &#39;com.google.android.gms:play-services-analytics:9.0.0&#39; 
     compile &#39;com.google.android.gms:play-services-maps:9.0.0&#39;
     compile &#39;com.google.android.gms:play-services-location:9.0.0&#39; 
     compile &#39;com.google.android.gms:play-services-gcm:9.0.0&#39; 
     compile &#39;com.google.android.gms:play-services-base:9.0.0&#39;

**EDIT**
disabling GCM fixed the problem, so my guess is I should migrate to Firebase Cloud Message 

**EDIT2**
My device receive Google Play Services 9.0 (yesterday was 8.4.x). Now it doesn&#39;t crash anymore, but complain about module descriptor 

     Failed to load module descriptor class: Didn&#39;t find class &quot;com.google.android.gms.dynamite.descriptors.com.google.firebase.auth.ModuleDescriptor&quot;
     Firebase API initialization failure.

Does anyone has a similar error, and how to fix it ?

**FIXED**
special thanks to @stegranet.
`./gradlew -q app:dependencies --configuration compile` helps you to identify what dependencies include SDK 24.x

Main issue is some library import the latest support library using `+` sign instead of a version. This cause the issue, by including the latest available version.

So avoid `+` sign in dependencies ;)


IncompatibleClassChangeError after updating to Android Build Tools 25.1.6 GCM / FCM

Since I upgraded the project with the latest version of google services and libraries (9.0.0), I have this strange issue :

[![Error build] [1]][1]

Grade console :

    :app:processDebugGoogleServices
    Parsing json file: /Users/cyrilmorales/Documents/Projects/mobilemeans-punainenristi/app/google-services.json
    :app:processDebugGoogleServices FAILED
    Error:Execution failed for task &#39;:app:processDebugGoogleServices&#39;.
    &gt; Missing api_key/current_key object
    Information:BUILD FAILED

build.gradle (root) :

    dependencies {
        classpath &#39;com.android.tools.build:gradle:2.2.0-alpha1&#39;
        classpath &#39;com.google.gms:google-services:3.0.0&#39;
    }

build.gradle (app) :

    dependencies {
        ....
        compile &#39;com.google.android.gms:play-services-analytics:9.0.0&#39;
        compile &#39;com.google.android.gms:play-services-gcm:9.0.0&#39;
        compile &#39;com.google.android.gms:play-services-maps:9.0.0&#39;
        compile &#39;com.google.android.gms:play-services-location:9.0.0&#39;
        ...
    }
    apply plugin: &#39;com.google.gms.google-services&#39;

However, it works well with the play service libraries in 8.4.0 and google-services 2.1.0

Do you have any idea of the solution ?
