| H A D | android-changes-for-ndk-developers.md | 233 ## Text Relocations (Enforced for API level >= 23)
236 relocations. Such an approach reduces load time and improves security. This was
237 only a change for 32-bit, because 64-bit never supported text relocations.
239 The usual reason for text relocations was non-position independent
254 the TEXTREL entry declares that the .so contains text relocations.) This
264 entry/flag but without any actual text relocations. This doesn't happen
266 you're not generating ELF files that claim to have text relocations,
269 *Potential problems*: Relocations enforce code pages being writable, and
271 linker issued warnings about text relocations from API level 19, but on API
272 level 23 and above refuses to load code with text relocations.
