[Q] Developed app runs on tablet but not phones

So i wrote a quick small app, a media player, real basic. It scans the internal and external storage for mp3s and you can click on an artist, then click an album, then click a track and then it plays. I was able to run the app in two different emulators, and then i was able to install and run it on my Huawei s7 tablet. I then gave a copy to my two friends to load onto their phones, but they won't play on the phones. One has a motorola droid and the other has a nexus 1. They install my app using 'apk installer' (downloaded from the market), and it seems to install fine, but it has to force close when they try to run it. The option on the phones to install non market apps is enabled. I am at a lose as to why it won't run on the phones but it will run on my tablet and emulators. My app needs to permission to the wake lock, i don't know if that has anything to do with it. My tablet does have z4root on it, but i only do temporary root sometimes. I hoping that the phones don't need to be rooted to run my app.
Anyone have any ideas or things for me to investigate to figure this out? I would appreciate any clues.

SOS!! Upgraded my XT720 from 2.1 to 2.2 and Screwed UP

Hi everyone
I am in need of urgent Help
I upgraded my Motorola Milestone XT720 from 2.1 to 2.2 using Cincinatti Bell Manual.
I referred this
http://www.cincinnatibell.com/milestoneupgrade/#howtoupgrade
Now, After successful upgrade, I have some serious issues
1) My Camera's Flash isnt working. I cant enable it.
2) Performance is low
3) Lost MotoNav. How can I get it back?
4) Even if I keep Pattern lock, the slide lock do appears
5) Also, How I can merge duplicate contacts? like one contact has 3 numbers saved that are same..
Thankyou

1. im not sure. should work.
2. performance is low. you can overclock using milestone overclock if you are still rooted. however, if you are not the kind who maintains you phone everyday, i suggest you go back to 2.1 as its the most stable.
3. just google motonav apk
4. thats a flaw in the rom, cant be fixed. if you'd like to try out custom roms and maintain you phone like most of us do here, then go ahead. its very exciting lol
5. you can merge duplicate contacts by signing in to gmail on a computer, click contacts and just look around the buttons. its called "find and merge duplicate contacts" if im not wrong.
hope this helped

1) Tried all level best best to start flash... It didnt. Installed Sleekcamera apk.
2) Google find and merge always crashes and unable to do the action
3) Whats overclocking? Is it a self explanatory software??
4) Dont feel like going back to 2.1...Love App2SD
5) I also have some issues - cant play HD video and my internal video player isnt working to its full potential as I am unable o avi file. I feel, that there is codec problem, as Ringdriod isnt working too...

if you like to have apps on your sd, there's a more advanced way to have it. i think its better than android's own move apps to sd. many roms we have around here have app2ext automatically set if they detect any ext partitions on your sd card. it moves all user apps onto an ext partition on your sd card (you have to use a partition tool to make this ext partition).
overclocking is actually just controlling your cpu clock speeds. most of us overclock our phone because it sometimes get laggy if we use the stock speeds. theres an app that helps us overclock on the market called milestone overclock. please remember that you need to be rooted do these stuff.
for the camera, you might have hardware problems. i dont know. contacts you should try doing the find and merge duplicates again. i'll upload a pic to show you what it looks like.
i recommend mioze's cm6 rom if you ever want to play around with flashing stuff. the stablest i've tried so far. Cyanogenmod is very versatile lol. there are a lot of themes for this rom too, made by Sileshn our master themer. for the videos i dont think i can help. you could try mobo player from the market (i think?)

Thankyou - Sorry to buggin u again n again. One last help

No bro. It used work fine before upgrade.

This is baffling for me. I feel like M not too smart for smartphone
for the videos i dont think i can help. you could try mobo player from the market (i think?)
Yup, I have that. Unable to to pay HD vid. It shows a lag of sound and vid. Tried soft decoding. Didnt work.

Couple of things about this. Are you still Rooted? CBW gave root permissions and then I think later in the tutorial they tell you how to give it back. Don't give it back. For what you want to do, you need to keep Root permission of your device.
Next are you comfortable with flashing custom ROMs and doing realtive non-beginner stuff on your phone. We can help you and walk you through stuff but unfortunately, there isn't an "app for that". If so, then here we go.
If you successfully were able to upgrade your phone, then you can do this. There are many custom ROMS in our forums that you can use. CM6, Hellmonger's, Kahl's V4, Bravo (wip) and CM7 (wip). I suggest CM6 or Kahl's V4 as they are stable enough for beginners to learn on. The have 99% working everything and what doesn't work, is either being fixed or there are already work-arounds. (search the development forums for these)
CBW's ROM doesn't have app2ext. It only has the native Froyo app2sd where you can go to settings>apps>pick your app>move to sd. This is not the same as App2ext or Link2sd. In these you have to partition your SDcard with an ext partition. Do you know how to partition your SD card? All the above ROMs do have the native Froyo app2sd, so if you don't know how to partition your SD card, that is fine too.
Answer those and then you can decide to move forward or not. It isn't hard and you don't have to be super smart to do it, although the more you read around, there are some seriously intelligent people in here. It is just from reading your posts above, how comfortable are you? You will not brick your phone and make it a paperweight, we can bring it back from the brink, if need be. We've done it before.
**Milestone Overclock is an app in the market (requires Root) that is free to download. Just download it and set it at preset 1000/66 and you'll definately seem a boost in performance.
**Google contacts. If merge doesn't work for you, go into google on PC and look at your contact and you may have some duplicates in there. When i first got it, i had 3 of everyone too. Also, go into your phone and go to settings>account/sync and see what is sycnhing. Side note: if you have a Google+ account, unsych that as everyone in your circles will be put on your phone and vice-versa.
**Moboplayer. I use this all the time and have no problem seeing HD vids. Might want to take another look at the preferences. It even says it on the thunmbnails that it is HD.
**Camera. If you don't like the the camera function, there are a few on the market (mostly paid though) that work well. I use Vignette, but there is Camera360 and I think one for LG too. If your flash isn't working though, that might be a hardware issue.
Figure out what you want to do with your phone (flash custom ROM or not) and we can help. If you already flashed the CBW upgrade, then you are really half-way there.
Also sorry for the manifesto sized response.

Hi
Actually thankyou for detailed resonse. I find it very helpful. But, M disappointed to tell, that in afternoon,I installed Moto-optimizer after I couldnt work on Motorola Overclock and Started the process at 800...and then, its only M logo which is showing up.
Will give it to service centre tomorrow and get back to 2.1. I hope, they are not ale to detect this s/w fault..

See this before you do the below. Easy read but might work for you instead of flashing back to 2.1.
Here is a recent troubleshoot that we fixed.

No need to take back to service. We can get you back to stock pretty easily.
All you need is to download RSDlite on your computer, install it and run it.

A few questions from a new Xoom owner.

Whats solutions are there for HDMI use?.
Are there any apps for true photo editing such as Paintshop pro or photoshop?.
My website uses flash but doesn't work properly on the tab.
http://www.cmorephotos.co.uk
I've tried the stock & Dolphin HD browsers.
I have a micro SD card installed but device won't let me delete from it says it's read only.
I use Plume twitter client but text doesn't seem sharp, I assume this is as its scaled and not tablet designed.
One of the main reasons I bought the device was for putting my large collection of photos on it.
I would be interested in any tips on making the experience better, one thing I would really like to be able to do is have the ability to rename the image or at least put a comment on it. I have scanned alot of old photos and would like to have this ability if a family member can tell me about the image.
Thanks for your time.

for the HDMI question, you can use any HDMI Micro (Type D) to HDMI (Type A)

There are no true apps that will give you the same abilities as Photoshop on a PC/MAC, but you can download Photoshop Express from the market.
I viewed your site using both the stock browser and Opera Mobile and it renders fine in Opera.
As for being unable to delete files from the SD card I believe that is a problem with the stock ROM, though could be wrong because as soon as I got my Xoom I rooted and put on a custom ROM, so have little experience of the stock ROM. Not sure if it has been fixed in the 3.2 update. I am using a custom ROM and can delete files on the SD card.
The latest version of Plume is tablet designed and the text is sharp on my Xoom.
As for managing your photos, perhaps an app like Media Organizer may be some way towards what you are looking for.

Still no Photoshop but you can use aviary. www.aviary.com/online/image-editor

Thanks for that. Will get a cable.
I looked at the docks too and would I be right in saying the the speaker dock is the only one that has HDMI out, seems pricey.

The Adobe photoshop tool suite is coming out for android (they said in November) and they will cost $9.99 per app. Hold on...this will only be getting better with Ice Cream Sandwich. The specs look great...I think a few of the cludgy Honeycomb bits will be resolved, from what I've been reading. It's going to be a great time to have a Xoom.

Photo shop Express only allows edit of images taken on device.
When viewing my site the gallery should come out of the bar and list sub catagories, I can't get it to do this in any of the 3 browsers
Found out about SD card issue shortly after posting.
Oddly though I can delete images from within the gallery app. - since found out this too be untrue its just temporary until reboot then they reappear

Go into settings and untick "Show camera photos only in Phone view". It will then show any photo's/pictures in any other folder that does not have the .nomedia file

sadly when you change the setting it shows all images rather than folders.
Thanks anyway.

[Q] Does phone need to be rooted for this reason?

I like to tinker with wearables like Pebbles,Sony Smartwatches, Android Wear Watches, Meta Watch, etc. I have purchased about 8 of these and have managed write apps to talk to the Pebbles via WP8 and Windows 7.
I have a Nexus 7 Kit Kat 4.4 tablet and have been able to download the official companion apps for some of the devices. Google Play will not let me download some of the APKs because they require a phone and a tablet isn't supported even though it usually works.
So what I would like to do is purchase a low cost, contract free, Android phone that has at least Kit Kat 4.4 on it and download the wearable companion app on it. Then use the Air Droid app to pull the companions wearable APK off the phone to the Nexus tablet.
The question is would I have to root the Android phone to be able to use Air Droid to pull a copy of th APK?

Google has blocked write access to the external SD card on Android 4.4. If you want to move files to the external SD card on Kit Kat, the phone has to be rooted. If you just want to copy files from it, this is supported.

That's not really true. Applications are not blocked from writing to the external SD card, they are just restricted to their own folder on the SD card. That said, it really has nothing to do with this topic since the OP did not mention using an SD card at all.
To answer your question, there are many applications that can backup APKs without using root like Astro, ES File Explorer, etc... I believe Airdroid is capable of doing so, but even if it's not there are other options. You could also definitely use Airdroid to get the APK off the device and onto your tablet once it is extracted using another application. Now, I can't answer the question of "will you be able to use the applications once you transfer them to your tablet?"

Debloating The SM-G360T1, SM-G360T & Others: An Easy Guide

There's not a lot of information out there for the Galaxy Core Prime on how we might debloat and save more space, so I decided to make a short tutorial that might help people with some easy steps in cleaning up their device. This guide is meant to be pretty basic and to just help point people in the right direction so that it speaks to a broader scope of Galaxy Core Prime Models, but is based specifically on the SM-G360T1. The SM-G360T is essentially the exact same phone though, so all of these steps should apply directly to that device too. Other Galaxy Core Prime models will be able to use this as well, but just be sure to read the special "NOTE" part of each step. Also, I'm sure it goes without saying, but inevitably I'll get the question, so obviously, root is required for this!
Anyhow, here we go:
1) Do a full backup in recovery before deleting system stuff. This is always a good idea just in case you delete something you're not supposed to and android stops working, then you can just go into recovery(TWRP, CWM, etc.) and restore your backup and your back to square one. It's good to do a new backup too a few days after when you're sure your deleted apps aren't causing any problems so you can restore to that slimmer version later if need be. Also, you should probably save your backup files to the external sd as you will likely have more free space there.
2) Install a debloated rom in recovery. SlimPickins is a great one for the SM-G360T1. It's basically the stock firmware for the MetroPCS Core Prime, but thanks to @Koognod we can now run Android without all the extra junk using his rom. It comes already debloated, deodexed and deknoxed, so you can just install it and not have to deal with finding all the junk to delete for yourself. It's already gone! It's also great for speeding up your bogged down phone or creating more space for your apps and media. Here is the link.
http://forum.xda-developers.com/gal...rom-slimpickins-stock-rooted-bloated-t3250883
NOTE: YOU CAN NOT INSTALL THIS ROM IF YOU DO NOT HAVE THE SM-G360T1. It should work fine on the SM-G360T too, but for anyone else just try googling or searching XDA for your "model #" and "debloat rom".
3) I recommend deleting the "PreloadInstaller" folder from "/system/app/" with a Play Store root browser. You should do this before deleting any system apps in my opinion, as this folder contains an apk that is programmed to put back a lot of the system stuff you delete(either immediately or after reboot). If you don't feel comfortable deleting this folder just yet though, then you can just move it to your external sd card for now with your browser to save space in case you ever want to move it back or just skip this step. Your choice!
NOTE: If you don't have the SM-G360T1 or SM-G360T, then your "PreloadInstaller" folder may be called something slightly different or you may not even have it at all. Just look for something similar in there. Be careful not to delete the package installer though as that's the program that allows you to install apps yourself.
4) You need an app that uninstalls system apps. I use "System App Remover(ROOT)" from the Play Store personally because all your deleted system apps actually go into a recycle bin first where they can be restored later if needed. It also tells you if the app in question is a "Key Module"(ie. proceed with serious caution).
5) Google search the internet for system stuff that's ok to delete for your device. It helps to search your model usually, but I don't think there's much info out there for the Galaxy Core Prime unfortunately, so just searching something like "Debloat Samsung Safe" can be a great resource as many Samsung phones have the same system junk.
6) Delete all the obvious stuff you don't want. This would be things like any of the MetroPCS stuff(or whatever carrier you have) or even the Galaxy app store if you don't want it. A lot of Google apps can be deleted too, though you want to be a little more careful with those as Android is pretty much based on the Google Services Framework and many Google apps are tied into the system. Generally, apps like Chrome, Docs, Drive, Hangouts, Maps(if you prefer another map application like Waze or whatever), etc. are good to go if you want. I wouldn't delete any of the core Google apps though that may handle major processes on your phone, like Calendar, possibly even Gmail or any of the ones that you don't know what they do. Deleting the stock camera, gallery, video or music player may sometimes give you problems down the line too, so I would probably keep those. You can also back all your apps up before deleting with Titanium Backup from the Play Store too in case you delete something that you need to put back later.
*NOTE: Some apps, like the Google ones for instance, may cause popup errors after you delete them. This is normal. Your phone's just looking for all those files that were just secretly running a few moments ago. All you have to do is reboot to get rid of those messages. If they still persist, then just reinstall the app.
7) Download an app to clean up that leftover mess. When you delete an app, especially with system stuff, it often leaves a bunch of folders and junk behind. Go to the Play Store and download an app that allows you to clean all that up. There's lots of good ones. I like to use one called "SD Maid" myself. It's good at cleaning up those leftover files and has a feature called "CorpseFinder" in fact that does just that. It also cleans up a lot of other things on your phone.
Anyhow, if you're a heavy power user like myself or you store a lot of music or other media on your phone in addition to 20 million apps or so and you need more space, then I hope this helps you out. Take care guys. Thanks!

Out of curiosity, how does this affect the "phone unlock" feature? In case I want to change providers?

It won't affect it at all as long as you don't delete the "Device Unlock" app. More info on unlocking your device here:

Also, you can just install SlimPickins if you want an already debloated rom.
