And I thought I'd need to install the launcher prior to installing koreader.

Install an android launcher, better if it is optimized for e-ink, like https://www.mobileread.com/forums/sh...d.php?t=320940

Install KOReader and launch it from your new launcher.

.

Probably you can install apks on user storage too, with

adb install pakage.apk

but new installed applications won't be shown on the original launcher.

If you get an error installing with adb install then you should push your apps to /system/app or /system/priv-app but I hope there is no need to do that.

Thank you very much for taking the time to help me,I really appreciate it.

What I forgot to mention is that I'm using nova launcher (2015 version by nightboy) and I see koreader icon after pushing the apk to /system/app/ but it fails to open saying it has stopped working or something else. Do you think changing the launcher is going to make a difference?
Btw I will try with adb install command but I highly doubt it'll work because as I said they have locked/limited the ability to install apps....

In that case you need to copy over the libraries, see https://github.com/koreader/android-...ment-520148127

If you place the app in /system/app libraries go in /system/lib or /vendor/lib
if you place the app in /system/priv-app/koreader libraries go in system/priv-app/koreader/lib/{arm,x86}

(I have no idea why Android doesn't just do that, but whatever…)

thanks,

but the link doesn't mention where to get them libraries

btw I tried

adb install

, no success as was expected.

What kind of error is thrown? Could you please paste it here?

It throws back this:

Performing Push Install
koreader.apk: 1 file pushed. 2.9 MB/s (32371441 bytes in 10.626s)
pkg: /data/local/tmp/koreader.apk
Failure [INSTALL_FAILED_INVALID_APK]

And I tried copying the libraries to /system/lib and /vendor/lib but no success either.

Btw my Android version is 4.2 and my device is a rk3026, 6 inch 220 dpi and 1ghz dual core cpu.
As I mentioned in my previous posts, it's Android is locked to prevent app installation by the vendor... So the only solution seems to be installing with the /system/app method since I want to keep the Original Rom....

Btw I Ran a logcat on KOReader and attached it below if you're kind enough to take a look.

thanks,

You could try resigning the .apk Not knowing what "they have locked/limited the ability to install apps" means it terms of how they actually implemented it. This would be an easy thing to try. I just use this one: EasyApkDisassembler.V1.3.2 to sign the .apk.

Please move the feedback to github to avoid duplication,

You brought up something very interesting, Thanks! But I didn't get most of it, how re-signing the apk could help us figure things out?

Congratulation to devlopers team.

Can you control the frontlight from Koreader on your Mimas? It's not working on mine

Thank you for your work on koreader.

I am testing the last release on my amoled android device and I wonder if it was possible to change the police color in night mode.

It would be great to have a greyscale choice instead of only white for the police when background is black.

I use to read in dark and it would more confortable with less brightness.

[NiLuJe]

If your device list is accurate, you can try OnePlus's "Reading" mode for KOReader (I assume it's going to be there on a 5T, I have it on a 6), it'll turn the app greyscale and sepia-ish, which I find works out pretty well in night mode.

Granted, this is a completely device-specific workaround, and has basically no relation to KOReader .

[Frenzie]

Also note the night mode toggle.
