[Question] Successful boot, no home or back buttons

[kaushal98]

Hi android-rpi team -

I was successfully able to build and boot RPi4 8 GB from this repo. However, when the system boots there are no system buttons and all the UI has is just 2 apps -System Tracing and Settings.

Can someone please advice if this is expected? Or somehow my build or boot is not right?

Here's a screenshot after the system has booted.

Thanks.

Hi
Your screen is normal.. It just RpLauncher app.
If you expacted other screen, you can install other Launcher app.

The default build is a TV device plus a custom launcher. To have the navbar + statusbar, first make it a tablet then remove the RPLaucnher and use the default launcher. As in here:
https://github.com/hkoosha/device_arpi_rpi4

To use that repo, you need to have https://gitlab.com/openrpi/rpidroid/vendor/openrpi/taskbar and https://gitlab.com/openrpi/rpidroid/vendor/openrpi/calculator in your AOSP source tree.

Thanks everyone. I didn't realize from the ReadMe that this repo builds Android TV. Even though the patch does mention TvSettings, I didn't think it was actually TV.

Hi @hkoosha since there is no readme in that repo, are the build instructions same as in this one? Sorry newbie here :)

They are mostly the same, but you need to run lunch erpi4-eng instead of lunch rpi4-eng

Hi @hkoosha and everyone
Since I applied your new guide of a tablet and default launcher "https://github.com/hkoosha/device_arpi_rpi4",
my android isn't booted printing the gatekeeper abort() log and restarting init process.

I followed your README guide on this repo, and then I just modified the default.xml for applying new endorphin repo, like below,

<default.xml>
< remote name="arpi" fetch="https://github.com/android-rpi"/>
< remote name="hkoosha" fetch="https://github.com/hkoosha"/>

< remove-project name="platform/external/mesa3d"/>
< project path="external/mesa3d" name="external_mesa3d" revision="v3d-20.1" remote="arpi"/>
< project path="external/drm_gralloc" name="external_drm_gralloc" revision="v3d-20.1" remote="arpi"/>

< project path="kernel/arpi" name="kernel_arpi" revision="arpi-5.4.y" remote="arpi"/>

< project path="device/endorphin/erpi4" name="device_arpi_rpi4" revision="arpi-10" remote="hkoosha"/>

Is there anything that I missed?
I would really appreciate it if you help me, Thanks
