In android JUnit test, we may need to know if the target app is debug version or release version.
Context mContext = InstrumentationRegistry.getTargetContext();ApplicationInfo mApplicationInfo = mContext.getPackageManager().getPackageInfo(PACKAGE_NAME, 0).applicationInfo;boolean isDebuggable = (0 != (mApplicationInfo.flags & ApplicationInfo.FLAG_DEBUGGABLE));
And we can check other flags using this, FLAG_ALLOW_CLEAR_USER_DATA
etc.
As for &
in inta & intb
:
int a = Integer.parseInt("1010", 2);int b = Integer.parseInt("0111", 2);System.out.println(a & b);System.out.println(Integer.toBinaryString(a & b));
prints:
210
