Common mistakes when working with AndroidManifest

When working with the AndroidManifest.xml file, developers often encounter common mistakes that can lead to application errors or unexpected behavior. Understanding these pitfalls can save time and improve app functionality.

Common Mistakes

  • Missing Permissions: Forgetting to declare necessary permissions can result in functionality issues.
  • Wrong Activity Declaration: Not properly specifying the main activity can prevent the app from launching.
  • Incorrect Package Name: The package name must match the application's actual package; otherwise, the app may fail to install.
  • Misconfigured Intent Filters: Not properly setting up intent filters can lead to user navigation issues.
  • Debug vs Release Configurations: Neglecting to adjust configurations for different build variants might expose sensitive parts of an app.

Example of a Correct AndroidManifest Configuration

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myapp"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
