Quote but if I add  in uses
SynCommons    ,mORMot  ,mORMotSQLite3, SynSQLite3Static
app crash at startup.
You can try copy these units to "/jni"  project folder....

QuoteAlso AppmORMotDemo1 crash....
yes, this is just the skeleton of an application.... you need complete
the project with  all
mORMot stuff. You read this hint here
"....\demos\GUI\AppmORMotDemo1\mORMot"
"--putmORMotSourceHere--"

@schumi
With mORMot there are different units for different operating systems.
The unit SynCommons will work with Windows operating system, for
example.
For Android you need to use the SynCrossPlatform* units.

Look within the manual "17. Cross-Platform clients" and '17.1.1.
Delphi FMX / FreePascal FCL cross-platform support'.
The manual is Synopse    'Software Architecture Design'.

On Android it is not advisable to pull in any Windows mORMot units.

standard mORMot units (Syn*.pas & mORMot*.pas) works fine for Android
+ LAMW. Try to use older mORMot (October/December 2018), I have some
troubles with latest mORMot on Android but not time yet to
investigate.

What is your Android version?
What is your mORMot version (exactly version - for version goto
SynopseCommit.inc file in mORMot directory)?
What is your FPC revision/version?

also static linking for SQLite3 with Android + mORMot will not work
(even SynSQLite3Static.pas has no meaning here - the dynamic so file
will be loaded). You need to manually add right version of SQLite3 to
your apk. Here you have precompiled binaries:
https://www.sqlite.org/download.html (Precompiled Binaries for
Android). Change *.aar extension to *.zip and get proper *.so file
from archive (probably jni\armeabi-v7a\libsqliteX.so is right choice -
but you need to change libsqliteX.so name to libsqlite.so).

Otherwise standard SQLite3 from Android will be loaded.

Hi, schumi @schumi

mORMot for Android ,please use this:

mORMot for Windows ,please use this:

I have in production mORMot v1.18.4912 . Your Android seems fine.
Required API should be >= 20 because mORMot uses "getpagesize" from
libc which was introduced in Android 4.4W (not all KitKat versions).
