[Amazfit] fazy33:
I agree but from the log cat i have the following error

E/AndroidRuntime( 1569):	Caused by: java.io.IOException: Failed to open oat file from /system/app/WeeklySports/mips/WeeklySports.odex (error ) (no dalvik_cache availible) and relocation failed.

but it exists your are right.

So Android try to read the classes.dex in apk but it has been removed when apk has been optimize...

I guess i should be located in /data/dalvik-cache/mips/ but it miss on my watch.

If some one got it i could copy here to test

root@watch:/# ll /data/dalvik-cache/mips/system@app@*
