Manifest merger failed : uses-sdk:minSdkVersion 14

Since downloading the latest SDK and installing Android Studio, my project fails to build. I get the following message:

Error:Gradle: Execution failed for task ':SampleProject:processProdDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version L declared in library com.android.support:support-v4:21.0.0-rc1

Solution 1:

Note: This has been updated to reflect the release of API 21, Lollipop. Be sure to download the latest SDK.

In one of my modules I had the following in build.gradle:

dependencies {
    compile 'com.android.support:support-v4:+'
}

Changing this to

dependencies {
    // do not use dynamic updating.
    compile 'com.android.support:support-v4:21.0.0' 
}

fixed the issue.

Make sure you're not doing a general inclusion of com.android.support:support-v4:+ or any other support libraries (v7, v13, appcompat, etc), anywhere in your project.

I'd assume the problem is v4:+ picks up the release candidate (21.0.0-rc1) latest L release which obviously requires the L SDK.

Edit:

If you need to use the new views (CardView, RecyclerView, and Palette), the following should work:

compile "com.android.support:cardview-v7:21.0.0"
compile "com.android.support:recyclerview-v7:21.0.0"
compile "com.android.support:palette-v7:21.0.0"

Another Edit

Be sure to see @murtuza's answer below regarding appcompat-v7 and upvote if it helps!

Solution 2:

Also, in case you are importing the appcompat-v7 library make sure you tag a version number at the end of it like so:

compile 'com.android.support:support-v4:19.+'
compile 'com.android.support:appcompat-v7:19.+'

After only changing the support-v4 version, I still received the error:

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version L declared in library com.android.support:support-v4:21.0.0-rc1

It was a bit confusing because it looks like v4 is still the problem, but, in fact, restricting the appcompat v7 version fixed the problem.

Solution 3:

Solution 1:

Change uses-sdk to <uses-sdk tools:node="replace" /> and add xmlns:tools="http://schemas.android.com/tools" in AndroidManifest.xml

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.demo.android"
    android:versionCode="16"
    android:versionName="3.3.1">
    .
    .
    <uses-sdk tools:node="replace" />
    .
    .
</manifest>

Make sure you use gradle 0.11 and above to use Manifest merger.

Solution 2:

• Change compile 'com.android.support:support-v4:+' to compile 'com.android.support:support-v4:20.+' in build.gradle. This will prevent gradle from using v4:21.0.0 that requires version L.

• However, if your any of your external dependencies uses the same. You will probably have to wait for them to update the same.

Solution 3:

• Remove/Comment <version>21.0.0-rc1</version> in your file <android-sdk>/extras/android/m2repository/com/android/support-v4/maven-metadata.xml

• Repeat the same for support-v7

Solution 4:

<uses-sdk tools:node="replace" />

No longer works.

change uses-sdk to

<uses-sdk tools:overrideLibrary="com.packagename.of.libary.with.conflict" />

and add
xmlns:tools="http://schemas.android.com/tools" in the AndroidManifest.xml file
