Android. Read NVItems from Java. System permissions. - GSM-Forum

Decker82 · 08-25-2014, 11:21

Hi, all! There is one question for android guru ... I have a one android device on Qualcomm and trying to write Android App to read some needed NVItems. I am newbie into Android, and this is my first expirience with Eclipse and Java

I have qcnvitems.jar from firmware of this device, and add it as an external jar in Project. Also i make import com.qualcomm.qcnvitems.QcNvItems and create QcNvItems object, and try to read NVItems as mqcNVItems.getNvItemData(...).

But there is one problem. Permissions. When i try to execute app in logcat i see:

Code:

08-25 02:03:05.644: E/AndroidRuntime(8890): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.deckertest/com.example.deckertest.MainActivity}: java.lang.SecurityException: Not allowed to bind to service Intent { cmp=com.qualcomm.qcrilmsgtunnel/.QcrilMsgTunnelService }

I understand this happens because i wrote user-level app, and to get needed permissions - app must be system.

How can i get this permissions? Any hints? May be exist a way to build update.zip with my app and sign it somehow to install in /system? (there is no CWM, only stock recovery, is any way to sign custom zip to use it with stock recovery?)

You wanna sign update.zip... sounds very funny.

I was patch <3e> stock recovery to remove signature checking and get root via my update.zip

But there is another question. I still can't use methods from library qcnvitems.jar in my app. I try to add android.permission.ACCESS_SUPERUSER to manifest, also i try to move my app to /system/app. But still get error above - "Not allowed to bind to service Intent".

Why system app haven't this privelegies? May be i miss something? Is anybody here, who use qcnvitems.jar in your own apps?

You need to check com.qualcomm.qcrilmsgtunnel/.QcrilMsgTunnelService and see why its not allowing. It maybe possible that you need other permissions or that you may need to run as phone user because system user doesn't have those permissions. Which phone model and android version are you trying on?
Also pull file /data/system/packages.xml and post it here.
