How to build Android SDK for iMX8MQ EVK?

[trongthinh]

I am trying to build an SDK for iMX8MQ EVK. Below are my step:

1. source build/envsetup.sh

2. lunch evk_8mq-userdebug

3. make -j 8 (This step build android image => success)

4. make -j 8 sdk (This step build SDK => Failed)

I got these error

Can someone have any solution or hint? Many thanks for replying me.

Hi Thinh Nguyen,

I think I have this working now, it appears to generate an sdk, although I have not tried it yet.

I think the full steps are:

1. Do the standard build

lunch sabresd_6dq-eng

make

2. Build the missing tools

make dmtracedump
make etc1tool
make split-select
make bcc_compat
make apksigner
make dx

make libaapt2_jni

make layoutlib-legacy

3. a) Edit the file development/build/sdk.atree to comment out the reference to userdata.img

##############################################################################
# System image Component
##############################################################################

# System images + Kernel
system.img                                 system-images/${PLATFORM_NAME}/${TARGET_CPU_ABI}/system.img
ramdisk.img                                system-images/${PLATFORM_NAME}/${TARGET_CPU_ABI}/ramdisk.img
#userdata.img                               system-images/${PLATFORM_NAME}/${TARGET_CPU_ABI}/userdata.img
system/build.prop                          system-images/${PLATFORM_NAME}/${TARGET_CPU_ABI}/build.prop

# Note: the kernel image is handled by sdk-android-<abi>.atree now.

3. b) Alternatively, it appears that you can enable the creation of userdata.img (I have not tried this): https://community.nxp.com/docs/DOC-105198

4. Edit the file development/build/sdk.atree (again) to comment out the reference to EmulatorSmokeTests.apk

##############################################################################
# Tests Component
##############################################################################
#system/app/EmulatorSmokeTests/EmulatorSmokeTests.apk tests/emulator-test-apps/EmulatorSmokeTests.apk

5. Build the sdk

make sdk

Hi Brian Lee,

That sounds cool, thank for update status.

Hi,

You can refer to the Android_User's_Guide.pdf in NXP website. And the thread https://community.nxp.com/docs/DOC-340804 maybe do help for you.

Have a nice day

Rita

Hi Rita Wang,

Thank you for answer although it does not solved my issues. For Embedded System, we some time modifies Android framework that why we need to build SDK. I hope in the future NXP will help.

Hi Thinh Nguyen,

Did you solve this issue?

I am seeing the same thing when trying to create the SDK for the i.MX 6 Sabre board (MCIMX6Q-SDB).

Hi Brian Lee,

I am sorry I cannot solve this issue. I am learning SDK from Raspberry PI 3. I hope I can port to iMX6.

Hi Thinh Nguyen,

I have made some progress on this.

The issue seems to be that there are some missing dependencies. If I run the following commands, I can get further in the build process:

make dmtracedump
make etc1tool
make split-select
make bcc_compat
make apksigner
make dx

I now get the following error that I am debugging:

lunch sabresd_6dq-eng

make -j2 sdk

A little more progress:

If you do:

make libaapt2_jni

make layoutlib-legacy

It resolves two of the missing source file errors above. Now to solve the userdata.img problem...
