Encountering the “Manifest Merger failed with multiple errors” in Android Studio can be a daunting experience, especially for beginners. This error typically occurs when there are conflicts or issues within your AndroidManifest.xml file or between this file and other dependencies. This article will guide you through the most effective solutions to resolve this issue.
Understanding the Error
The “Manifest Merger failed with multiple errors” error suggests that there are conflicting attributes or entries in your AndroidManifest.xml file. This can be caused by:
- Duplicate activity declarations
- Conflicting permissions
- Inconsistent SDK versions
- Issues with external libraries
Steps to Resolve the Error
1. Use the Merged Manifest View
One of the most efficient ways to identify and resolve manifest merging issues is by using the Merged Manifest view in Android Studio. Follow these steps:
- Open your AndroidManifest.xml file.
- Click on the “Merged Manifest” tab at the bottom of the editor pane.
- Examine the right column for errors and warnings.
- Address the errors as indicated.
For instance, if you see an error related to the android:allowBackup attribute, you can instruct the compiler to ignore this attribute from external libraries by adding the following lines in your application tag:
<application
tools:replace="android:allowBackup"
xmlns:tools="http://schemas.android.com/tools">
</application>2. Remove Duplicate Activity Declarations
Ensure that each activity is declared only once in your manifest file. For example, if your manifest contains:
<activity android:name=".MainActivity" />And:
<activity
android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>Remove the first declaration to eliminate ambiguity.
3. Consistent SDK Versions
Ensure that the minSdkVersion and targetSdkVersion in your build.gradle file are consistent with those in your dependencies. For example:
defaultConfig {
minSdkVersion 23
targetSdkVersion 30
}4. Handle External Library Conflicts
If the error arises from an external library, you can add the tools:replace attribute to handle specific conflicts. For example:
<manifest xmlns:tools="http://schemas.android.com/tools">
<application
tools:replace="icon, label"
android:label="myApp"
android:icon="@drawable/ic_launcher">
</application>
</manifest>Conclusion
By following these steps, you should be able to resolve the “Manifest Merger failed with multiple errors” in Android Studio. Always ensure to check the Merged Manifest view for detailed error reports and make the necessary adjustments in your AndroidManifest.xml and build.gradle files.
