    bpo-26934 skipped some tests of test_faulthandler on Android API < 24 to fix the problem that python does not crash upon _sigsegv(). But the same problem occurs on API 24 except randomly, you need to run test_faulthandler many times before reproducing it, see below few results in that case.

    I propose to skip those tests whatever the value of the Android API level.
    In that case the test.support.requires_android_level decorator is not used anymore and should be removed.

    Works for me.
