+# ARM compilation. TODO
+Create standalone: https://developer.android.com/ndk/guides/standalone_toolchain
+Then change variables for you in setenv-android.sh and preparedepencies.sh ($ST and $NDK_PATH will be for standalone) but ANDROID_NDK_ROOT for real NDK-bundle.
+then run preparedepencies.sh
+then go to ../src/ and run compile_android.sh
+Or change variables in gostcoin-qt-android.pro and compile for Qt...

+You can to try change -lc to LMODE2 in makefile.android but then you will to get segmentation fault. TODO: fix it...
