Why Does My App Force Close When Putting Extra HTML Content in an Intent?

Maximum Length of Intent putExtra Method: Force Close

Question:

Facing force close while attempting to switch activities after using putExtra to pass HTML content obtained from a webView. Suspecting the HTML string size to be the cause.

Answer:

The issue arises from the limitation of the putExtra method in an Intent. According to documentation, you can parcel up to 1MB of data in a Bundle for IPC. However, this limit can be lower in scenarios with high transaction volumes.

Solution:

To address this issue, consider using an alternative method to transfer the HTML content:

• Save Content to a Temporary File: Store the HTML content in a temporary file and pass the path or URI of the file to the second activity. The second activity can then read the content from the file.
• Use Shared Preferences: Incorporate SharedPreferences to store the HTML content. This option is more straightforward, but may not be suitable for large datasets.

Additionally, the following steps may help with debugging:

• Try Using Parcelable Object: Convert the HTML content to a Parcelable object and pass it as an extra instead of a string.
• Check for Exceptions: Review the force close message (if available) or use a debugging tool to identify the specific line of code causing the issue.
