Research direction
The issue requests adding FLAG SECURE to the DexterActivity class to prevent screenshots and screen recording. This involves modifying the onResume or onCreate method in DexterActivity.java (located in the library source) to call getWindow().setFlags(WindowManager.LayoutParams.FLAG SECURE, WindowManager.LayoutParams.FLAG SECURE). The change is localized and does not require understanding of the entire library, but familiarity with Android window flags is needed. Check the current implementation of DexterActivity to ensure the flag does not interfere with the permission request flow. The issue was opened in 2019 and has no subsequent activity, so it's a good candidate for a first time contribution if maintainers are still active.
