Screen flickering on Android when entering inputs in an Ionic framework application can be caused by various factors. Here are a few potential solutions to address this issue:

  1. Use the Cordova Keyboard Plugin: Install the cordova-plugin-ionic-keyboard plugin, which provides better handling of the keyboard events and can help prevent flickering. Run the following command to install the plugin:

    cordova plugin add cordova-plugin-ionic-keyboard

    This plugin should be automatically installed when creating a new Ionic application, but it's worth verifying if it's present in your project.

  2. Adjust the android:windowSoftInputMode attribute: In the AndroidManifest.xml file, locate the activity where the flickering occurs and add or modify the android:windowSoftInputMode attribute to adjust the window behavior when the soft keyboard is displayed. For example, you can set it to adjustPan to prevent resizing the window and potentially eliminate the flickering:

    <activity android:name=".MainActivity" android:windowSoftInputMode="adjustPan">
  3. Use the @ionic-native/keyboard Plugin: Install and use the @ionic-native/keyboard plugin, which provides a higher level of control over keyboard events. You can listen to keyboard events and adjust the layout accordingly to avoid flickering. Refer to the official Ionic documentation for details on how to install and use this plugin.

  4. Optimize CSS and Layout: Review your CSS styles and layout structure to ensure that they are optimized for performance. Avoid unnecessary animations, transitions, or heavy computations that could contribute to the flickering issue.

  5. Test on Real Devices: Sometimes, the flickering issue is specific to certain Android devices or versions. Test your application on different real devices to identify if the flickering is consistent across all devices or if it's limited to specific ones.

  6. Update Ionic and Cordova Versions: Ensure that you are using the latest versions of Ionic and Cordova. Newer versions often include bug fixes and improvements that may address the flickering issue.

If the issue persists after trying these solutions, it may be helpful to provide more specific details about your Ionic version, the code related to the input fields, and any related error messages for further assistance.
