Invalid register: v17. Must be between v0 and v15, inclusive.

I encountered an APK that is using .locals 17 under OnCreate function in com/ctugames/km2/TiredBirds.smali

invoke-static {p0}, Lcom/xxx/xxx/Main;->Start(Landroid/content/Context;)V

like

.method public final onCreate(Landroid/os/Bundle;)V
    .locals 17

    invoke-static {p0}, Lcom/xxx/xxx/Main;->Start(Landroid/content/Context;)V

But Apktool does not let me compile

I: Using Apktool 2.9.3
I: Checking whether sources has changed...
I: Smaling smali folder into classes.dex...
com.ctugames.km2\smali\com\ctugames\km2\TiredBirds.smali[1951,4] Invalid register: v17. Must be between v0 and v15, inclusive.
Could not smali file: com/ctugames/km2/TiredBirds.smali

I changed it to .locals 16 which is max register, but it crashes

I never had this problem adding a line below OnCreate until now. What should I do?

Well thats odd - if Apktool (smali) disassembled into an invalid state - either it was intentionally like that to thwart this type of effort or a bug in smali.

Nevermind, I replaced invoke-static {p0} with invoke-static/range {p0 .. p0} and it works now
