Avoid StrictMode warnings

[stefanosiano]

📜 Description

SentryAndroid.init now sets strictMode to Lax and reset it after it finishes
Removed few useless IO calls

💡 Motivation and Context

Closes #4261

💚 How did you test it?

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

I found we were filtering the files in the directory, but then looped over all the files anyway
Was it by design or by accident?
And is there any risk in changing this?
