Unable to start activity ComponentInfo

[Rudloff]

Hello,

2.0 crashes when I launch it on my Android 4.2.1 tablet:

Fairphone Launcher was shipped for Lollipop with the Fairphone 2. It should probably be compatible only from Android 5 onwards.

We could bump its minSdkVersion to a Lollipop one or (painfully) debug Android 4 compatiblity.

[Rudloff]

I also thought it didn't work because of 4.2 but it works correctly on another one of my devices that runs Android 4.2.4.

[Roboe]

Android, :man_shrugging:, hahaha, :joy:

[ildar]

@Roboe , may I ask not bumping minSdkVersion because:

1. @Rudloff reports that FPL runs good on some JB Androids
2. The choice of launchers running on JB and KK is shrinking while people still using their 5 years old tablets. FPL may be very handy in the situation. Please?

[Roboe]

Hey, @ildar, that was an earlier workaround before I jumped back into maintaining these apps. Thank you for caring and giving real-world context on this issue, :grinning:.

@Rudloff, could you test if this issue is still valid on your tablet with the current master build? We updated support libraries and build tools. I'll debug the code in the meanwhile.

[Rudloff]

Unfortunately, it still crashes.

FP2-Launcher 2.1 doesn't crash on my Fairphone 1 running Kitkat 4.4.2.

[ildar]

That's good. Yet not good enough to run it on JB :((
