Trouble Installing Autodroid 1.2 on Nexus 7

So I've been attempting to install Autodroid 1.2 on my Nexus 7 Grouper, but I can't seem to get the bugger going. The tablet originally had Lollipop (5.0) installed.

So here is what I did:

1) Installed the stock 4.4.4 ROM (Build Number KTU84P)

2) Installed Bootloader 4.23

3) Installed TWRP 2.7.1.1

4) Installed SuperSU (rooted the tablet).

5) Performed a normal wipe.

6) Installed Autdroid 1.2 for Grouper

After doing the above, and going to the "about tablet" setting, it displays the following:

Kernel version: 3.1.10-kangaroo

Build Number: KTU84P

So it looks as though the kernel installed fine, but the ROM itself doesn't look the part.

A few more things to note, OTG seems to be kind of funky. I can insert a USB drive and mount it using Stickmount, but the drive doesn't show up under Settings->Storage.

Oddly enough, charging with OTG works.

Any help would be very much appreciated.

You need to enable root access to power event manager. Find the instructions on the first post of the autodroid mod.

---------- Post added at 12:51 PM ---------- Previous post was at 12:08 PM ----------

As far as I understand the settings for firm sleep only apply when a OTG cable with a power supply is connected. You also need to enable Fixed install mode and for this you need to allow root access to Power Event Manager app..

Finaly someone replied :) ok, so I can't use autodroid rom without otg cable :/ damn :( I must modifie my dash to put otg cable in it :/ thats the problem ;/ any other ideas??
[Nexus 7 Q&A, Help & Troubleshooting] SimplifiedBacon:
If you just want the screen to come on, then I guess you could enable wake up on charge in the display menu of the options. Then to prevent the screen to go to sleep while your charger is connected, you need to enable developer options (find the instructions on slimKat webpage) and select "Stay awake" (screen will never sleep while charging).

Does this solve your problem?
[Nexus 7 Q&A, Help & Troubleshooting] TomCat_s:
Unfotunately its not working :( maybe im doing something wrong O.o ill describe everything from the begining:

Charger is unplug, tasker is disabled so im pressing power icon on power event manager and nexus goes to sleep with powerdown animation without any problems screen goes off. Than i plug charger and nothing so i press button on the side, screen goes on but its not charging, unplug and plug again while screen is on and its charging. Another question is how set up power event manager to put nexus to sleep automaticly when charger is unplug?
[Nexus 7 Q&A, Help & Troubleshooting] michiil:
Okay so first off all the powereventmanager fixed installation mode only workes with otg. So your tablet wont be put to sleep when only using a chager. In this case i suggest disabling the fixed installation mode and contol it via the tasker plugin.

Now your other problem sounds really weard..

You could try cleaning data from powereventmangr and than clearing the root permisson from the built in superuser. The start start powereventmanager and grant it root..
[Nexus 7 Q&A, Help & Troubleshooting] SimplifiedBacon:
I think I might have an even weirder problem.

I've installed the rom and everything worked okay for a few days including charging via OTG, fixed install mode and behringer UCA202 DAC playback. Then one day it just stopped working.

First I've assumed it was an USB otg cable that I made so I replaced that with a store bought one today. It still didn't work so I tried flashing the ROM again. Now the USB light on the UCA202 turns on, when I'm booting the nexus, but as soon as I unlock the screen it turns off and the DAC stops working and music is playing back through the built in speaker.

After some testing it appears that if the fixed install mode is enabled, the USB DAC doesn't work and also USB host mode as tested by the USB Host diagnostics (results code 505210) shows limited 3rd party app support.

If I disable fixed install mode, the DAC starts working again (results code 505216). Although keep in mind that this is without the Y cable and plugged in charger, I have to test what happens when I put it in my car still.

EDIT: It seems it is now working. I had to connect everything in the car with the ignition ON, enable fixed install mode and then reboot the tablet with the ignition still ON. Then the DAC came to life and playback is working as intended. I do hope it keeps up the good work though.

Is there any extra precautions to take when removing the tablet from the car (I have a removable setup in a top glove compartment of an old mazda 6)?

Issue Reporting : Changing Icons in navbar

Hello,

The navigation bar settings have a great option to change the icons in the bar however to change the icon one has to chose from 1 of the 3 available options in the menu

1. Default

2. System Icons

3. Gallery

As you would imagine the 1st two options are not of much use and the third option doesn't let you change the icon with the message that the app did not provide the right outcome or it doesn't support cropping. Please use a different app - when there isn't an option to use any other image editor.

Audio playback jittery after waking from deep sleep

Hello, does anybody have any experience with this?

I'm using poweramp to play music over Behringer UCA202 DAC. The sound and everyting else is very nice, and the powerevent manager is now working correctly. It even resumes playback when I turn ignition back on. However playback gets really jittery after waking from deep sleep. If I then manually exit poweramp and let it sit on the home screen for a while and start it back up again, the audio playback is again great. I've tried increasing buffer length and audio thread priority in poweramp, but it's still doing this.

Now this is obviously not a critial issue, but would be nice to solve it anyway.

Thanks in advance for any insights.

Strange Sound Output

Dear All,

I have a very interesting issue with this ROM.

I realized that when the Tablet is fully charged, the sound that comes out of the Audio Jack connector has something like a little "electical" interference...

Do you remember when a 56k modem connected to the internet? That's pretty much what you can slightly hear in the background... so there's a noise and the music coming out of the audio jack is not very clear. :(

However if the tablet is really charging (because it was not at 100% anymore) then this "distortion" is not happening. The sound is clear.

Does anybody know why this happens? When I used Timur's USB ROM I didn't get this issue.

Could it be related to the PowerEventManager?

Thanks a lot for helping me guys!

Take care and have a very good day!!
[Nexus 7 Q&A, Help & Troubleshooting] michiil:
I never heard of this problem and this is properly because nobody here uses the audio jack. The sound quality of the nexus 7 is really bad so thats wa we use an usb dac.
[Nexus 7 Q&A, Help & Troubleshooting] The DON84:
Dear michiil,

Thanks a lot for your quick answer!

OK I understand. It seems that I can improve my setup in that case!! :D :D

Now pardon my question.

How can I do that?

I'm using a Griffin iMic at the moment.

But unforunately this doesn't seem to be recognized as a "USB DAC" device. Do I need to setup something special in your ROM to achieve this or is it simply the device that is not supported as USB DAC?

What I want: All the sound output (app indipendent) must go systemwide through the USB DAC device.

In case that my iMic device is not supported, which device do you reccomend?

Thanks a lot for your help and patience!

All the best,

Don

It seems most people use one of the following:

Behringer UCA 202 or

HIFIMEDIY SABRE USB DAC ES9023 96KHZ/24BIT

Behringer is cheaper, but Sabre allows a higher sampling rate (96 kHz vs 46 kHz for the Behringer).

Problem with the volume

Hi there guys, im new to all this but over the last 2 days ive managed to finally get this ROM working on my nexus 7, ive now however got another problem and i just cant seem to figure it out .. basically im using the autodroid 1.2 ROM for a car install and everything is working apart from one thing, when the power (OTG cable) is disconnected the tablet shuts down in to sleep mode like i want but when i reconnect the OTG cable it comes back on fine but my sound is turned off so everytime i turn my ignition on i have to increase the volume from the minimum to be able to hear my music .. i dont understand why its doing this, surely it should just pause the music then play it again once the tablets powered back on? however in my case as soon as the OTG cable is disconnected the volume goes to 0 then the tablet shuts down then when it fires back up again the volume remains at 0 .. any ideas people?

Many Thanks, Jack

Media buttons not working with a certain app running

Hi all. I'm facing a strange problem, which is critical for me:

When I'm running a Sygic satnav app (both in fore and background, both full and normal screen), the special AutoDroid media buttons (play/pause, next track, previous track) put in the navigation bar don't work. Just a touch sound is played but nothing more. Log displays appropriate information - after touching the buttons, no actions is fired.

With any other app, including another satnavs, they work as expected.

installation problems

For those of you having problems with power event manager, just flash kangaroo kernel (only kernel without rom) and everything should work. I had lots of problems installing this rom but i follow this steps.

Flash stock firmware 4.4.4 (i was on lollipop)

then flash slimkat rom for nexus 7 (you can find the rom on official slimkat website)

then flash autodroid 1.2 rom

Finally if you are having problems with powerevent manager or OTG conections just flash kangaroo kernel

And thats it, everything should work perfect.

battery drain rate and self powered hub

Hi, Autodroid has served me really well for the most part, but I always had to fight and worry about battery drain. The tablet would either charge slowly (+200mAh ish) with screen set to auto sleep and just music playing, BT/wifi/GPS turned off and no other apps running in the background.

For one thing, I am seeing at minimum 20ish mAh drain when left to firm sleep mode. I have every single wakelock blocked, and the power event manager seems to be working fine. What is considered a decent rate for most other people using it?

I have cleaned the USB ribbon cable thingy with vinegar + baking soda to remove oxidation, but did not get a chance to cover it with anything - could be a factor with the power drain. To combat this, I used thicker 16AWG wire to hack the OTG-y cable for direct power injection; that didn't seem to do much either, which brings us to my next question: I am using a self-powered hub, and assumed it needs to be fed with 5V power so hooked it up to another DC-DC converter. Seeing how that wasn't working, I have unplugged the 5V power to the hub. Some of the replies here though suggests I should be using a 12V power to the hub. What is the norm for self-powered hubs as far as input voltage goes? Thanks!

Now I know what you mean by erratic OTG behavior, the USB DAC I was using was getting disconnected everytime the tablet is awaken from sleep. That, and music would stutter during playback out of the blue for no good reason. Worst of all, not only fast charge wasn't working but power drain was actually worse than what I had with the included kangaroo 1.2 kernel.

No worries, had kangaroo kernel ready as a backup plan. Flashed it, rebooted, and got stuck on the google logo. Tried wiping cache/data and still the same thing. After repeated attempts, I ended up reloading the autodroid rom from the scratch - took me a good bit of time to download all the apps and get the settings the way I had it before.

The good news is, power drain/charging appears to be marginally better with ART (had to ditch xposed to switch) than what I had with Dalvik. The replacement USB ribbon cable is still somewhere in transit, let's hope that does the trick!
