Android SDK Requirements

Minimum SDK Version - Glide requires a minimum SDK version of 14 (Ice Cream Sandwich) or higher.

Compile SDK Version - Glide must be compiled against SDK version 27 (Oreo MR1) or higher.

Support Library Version - Glide uses support library version 27.

If you need or would prefer to use a different version of the support library you should exclude "com.android.support" from your Glide dependency in your build.gradle file. For example, if you’d like to use v26 of the support library:

dependencies {
  implementation ("com.github.bumptech.glide:glide:4.8.0") {
    exclude group: "com.android.support"
  }
  implementation "com.android.support:support-fragment:26.1.0"
}

Using a different support library version than the one Glide depends on can cause RuntimeExceptions like:

java.lang.NoSuchMethodError: No static method getFont(Landroid/content/Context;ILandroid/util/TypedValue;ILandroid/widget/TextView;)Landroid/graphics/Typeface; in class Landroid/support/v4/content/res/ResourcesCompat; or its super classes (declaration of 'android.support.v4.content.res.ResourcesCompat' 
at android.support.v7.widget.TintTypedArray.getFont(TintTypedArray.java:119)

It can also lead to failures in Glide’s API generator that prevent the GlideApp class from being generated.

See #2730 for more details.

Download

Glide’s public releases are accessible in a number of ways.

Jar

You can download the latest jar from GitHub directly. Note that you will also need to include a jar for Android’s v4 support library.

Gradle

If you use Gradle you can add a dependency on Glide using either Maven Central or JCenter. You will also need to include a dependency on the support library.

repositories {
  mavenCentral()
  maven { url 'https://maven.google.com' }
}

dependencies {
    compile 'com.github.bumptech.glide:glide:4.8.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
}

Note: Avoid using @aar in your dependencies whenever possible. If you must do so, add transitive = true to ensure that all necessary classes are included in your APK:

dependencies {
    implementation ("com.github.bumptech.glide:glide:4.8.0@aar") {
        transitive = true
    }
}

@aar is Gradle’s “Artifact only” notation that excludes dependencies by default.

Excluding Glide’s dependencies by using @aar without transitive = true will result in runtime exceptions like:

java.lang.NoClassDefFoundError: com.bumptech.glide.load.resource.gif.GifBitmapProvider
    at com.bumptech.glide.load.resource.gif.ByteBufferGifDecoder.<init>(ByteBufferGifDecoder.java:68)
    at com.bumptech.glide.load.resource.gif.ByteBufferGifDecoder.<init>(ByteBufferGifDecoder.java:54)
    at com.bumptech.glide.Glide.<init>(Glide.java:327)
    at com.bumptech.glide.GlideBuilder.build(GlideBuilder.java:445)
    at com.bumptech.glide.Glide.initializeGlide(Glide.java:257)
    at com.bumptech.glide.Glide.initializeGlide(Glide.java:212)
    at com.bumptech.glide.Glide.checkAndInitializeGlide(Glide.java:176)
    at com.bumptech.glide.Glide.get(Glide.java:160)
    at com.bumptech.glide.Glide.getRetriever(Glide.java:612)
    at com.bumptech.glide.Glide.with(Glide.java:684)

Maven

If you use Maven you can add a dependency on Glide as well. Again, you will also need to include a dependency on the support library.

<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId>glide</artifactId>
  <version>4.8.0</version>
  <type>aar</type>
</dependency>
<dependency>
  <groupId>com.google.android</groupId>
  <artifactId>support-v4</artifactId>
  <version>r7</version>
</dependency>
<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId>compiler</artifactId>
  <version>4.8.0</version>
  <optional>true</optional>
</dependency>

Setup

Depending on your build configuration you may also need to do some additional setup.

Permissions

Glide does not require any permissions out of the box assuming all of the data you’re accessing is stored in your application. That said, most applications either load images on the device (in DCIM, Pictures or elsewhere on the SD card) or load images from the internet. As a result, you’ll want to include one or more of the permissions listed below, depending on your use cases.

Internet

However if you’re planning on loading images from urls or over a network connection, you should add the INTERNET and ACCESS_NETWORK_STATE permissions to your AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package.name"

    <uses-permission android:name="android.permission.INTERNET"/>
    <!--
    Allows Glide to monitor connectivity status and restart failed requests if users go from a
    a disconnected to a connected network state.
    -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

    <application>
      ...
    </application>
</manifest>

ACCESS_NETWORK_STATE isn’t technically required to allow Glide to load urls, but it helps Glide handle flaky network connections and airplane mode. See the Connectivity Monitoring section below for more details

Connectivity Monitoring

If you’re loading images from urls, Glide can automatically help you deal with flaky network connections by monitoring users’ connectivity status and restarting failed requests when users are reconnected. If Glide detects that your application has the ACCESS_NETWORK_STATE, Glide will automatically monitor connectivity status and no further changes are needed.

You can verify that Glide is monitoring network status by checking the ConnectivityMonitor log tag:

adb shell setprop log.tag.ConnectivityMonitor DEBUG

After doing so, if you’ve successfully added the ACCESS_NETWORK_STATE permission, you will see logs in logcat like:

11-18 18:51:23.673 D/ConnectivityMonitor(16236): ACCESS_NETWORK_STATE permission granted, registering connectivity monitor
11-18 18:48:55.135 V/ConnectivityMonitor(15773): connectivity changed: false
11-18 18:49:00.701 V/ConnectivityMonitor(15773): connectivity changed: true

If the permission is missing, you’ll see an error instead:

11-18 18:51:23.673 D/ConnectivityMonitor(16236): ACCESS_NETWORK_STATE permission missing, cannot register connectivity monitor

Local Storage

To load images from local folders like DCIM or Pictures, you’ll need to add the READ_EXTERNAL_STORAGE permission:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package.name"

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    <application>
      ...
    </application>
</manifest>

To use ExternalPreferredCacheDiskCacheFactory to store Glide’s cache on the public sdcard, you’ll need to use the WRITE_EXTERNAL_STORAGE permission instead:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package.name"

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application>
      ...
    </application>
</manifest>

Proguard

If you use proguard, you may need to add the following lines to your proguard.cfg:

-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep public enum com.bumptech.glide.load.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

If you're targeting any API level less than Android API 27, also include:
```pro
-dontwarn com.bumptech.glide.load.resource.bitmap.VideoDecoder

VideoDecoder uses API 27 APIs which may cause proguard warnings even though the newer APIs won’t be called on devices with older versions of Android.

If you use DexGuard you may also want to include:

# for DexGuard only
-keepresourcexmlelements manifest/application/meta-data@value=GlideModule

Jack

Glide’s build configuration requires features that Jack does not currently support. Jack was recently deprecated and it’s unlikely that the features Glide requires will ever be added. If you’d like to compile with Java 8, see below.

Java 8

Starting with Android Studio 3.0 and version 3.0 of the Android Gradle plugin, you can compile your project and Glide with Java 8. For details, see the Use Java 8 Language Features on the Android Developers website.

Glide itself does not use or require you to use Java 8 to compile or use Glide in your project. Glide will eventually require Java 8 to compile, but we will do our best to allow time for developers to update their applications first, so it’s likely that Java 8 won’t be a requirement for months or years (as of 11/2017).

Kotlin

If you use Glide’s annotations on classes implemented in Kotlin, you need to include a kapt dependency on Glide’s annotation processor instead of a annotationProcessor dependency:

dependencies {
  kapt 'com.github.bumptech.glide:compiler:4.8.0'
}

Note that you must also include the kotlin-kapt plugin in your build.gradle file:

apply plugin: 'kotlin-kapt'

See the generated API page for details.
